Betsy Post 0:00
Alrighty. So welcome. Welcome everyone. I’m Betsy post. I’m with COLONTOWN, and I’m helping facilitate this evening’s presentation with Dr Hernandez. And I also have, of course, our esteemed Mayor Lindsey and one of the folks on the cabinet with me, Julie, who are also running tech support, you know, kind of any assistance that you might need, you can definitely ping Julie Lindsey myself. I will try to help in any way. We’re not technical experts, but we’ll, we’ll do our best. But I’m going to introduce our esteemed speaker, Dr Hernandez, if you’re familiar with COLONTOWN liver lovers, Lane transplantation station, our various groups dedicated to liver Mets within the COLONTOWN community. I know that he is not someone that’s a stranger to anyone here, so we’re really honored and really thankful to have him with us this evening to talk to us about the new kid on the block, liver transplant for metastatic colorectal cancer and why that’s taking off. So just a little bit of background about Dr Hernandez and I have Julie go to the next slide. I’m not going to read to everyone, but this will be available in the recording as well. But he is the chief of the Division of transplantation at the University of Rochester Medical Center. Before that, he was in Canada. He has an amazing background and did extensive training and live liver donor transplantation in Japan. It’s really impressive. He has over 110 he probably knows the specific number peer review publications in liver transplantation and other hepatobiliary topics, and he’s on the editorial board of this esteemed Journal of surgery. So we’re super excited, again, flattered to have him here. There’s no one I think that knows more, I guess, arguably, in my opinion, about this topic of liver Mets for metastatic colorectal cancer than Doctor Hernandez, just a couple of housekeeping things, kind of in the in the middle, if you will. We do want to take your questions, so it’s really important that we keep this, you know, interactive. I would request that you please put the questions in chat. So we are going to monitor chat, and we are going to come back to it after the presentation and go back to those questions. We really want to try to answer every question that everyone has. So please put those in chat so that we can go through them. We’re again going to really monitor those, look at them, make sure that we do go back and ask all of those questions. So please put those in chat, and if you have any questions about how to do that, you can ping one of us will try to help you. So, Julie, you can go to the next slide. And so thank you guys so much for being here, and I’m going to turn it over to Dr Hernandez to start the presentation again. Please put the questions in chat. Say hello and chat. If there’s anything that you hear that you have questions about or you think is interesting, put it in chat. So we’re going to be monitoring that, and we’re all happy to have you here tonight, so take it away. Dr Hernandez,

thank you, Betsy. Thank you Lincy, thank you, Claire, for this invitation. It’s always a pleasure to be in this group and to be part of it, once in a while, to be able to participate and guide patients I have dedicated the last many years of my career, a lot into this field of liver metastases, and I’m very happy and glad that we have been able to make progress in science, in medicine and surgery, and always try to push a little bit more the envelope to help more patients. And I like the title that it was assigned, that the new kid on the block. And I tried to find, I remember when I was younger, the New Kids on the Block. So I find this picture of them when they are 2022 they look a little bit older. They’re not kids anymore. And I think that’s exactly what happened to liver transplantation for colorectal metastasis. Is not a new kid, really. It’s new for a lot of us, but it already exists there for many years. So with this, I’m going to start. And last time, I don’t know how long ago was that, but probably a year or something like that, that I was invited by COLONTOWN to give a presentation, and I expanded a lot about colorectal liver metastasis, and then I talked about liver transplantation. Today, I want to concentrate much more in liver transplantation, but to being able to show the importance or why liver transplantation might play, or play a very important role, I want to talk. Back again, a little bit about all the background of colorectal liver metastases. With this, I want to show the this first slide, showing that you all know that is the third most common cancer. Colon cancer is the third more common cancer in the world, after prostate and breast cancer. So it’s not uncommon to have people like you or your beloved that has colon cancer, unfortunately, and it’s so common. But the good thing is that we make a lot of advancements in treatment, especially in chemotherapy, I would say, in the last 20 years. But unfortunately, there hasn’t been anything that is huge over the last 15 years for colorectal liver metastasis. We’re starting to do some changes, and I’m looking forward to, hopefully, within five to 10 years to be able to to have much more and more. But this slide is showing you impressively how colon cancer is increasing in these young population did from 20s, 30s and 40s. Look at the green part is showing how it’s increasing being the number of cases on this population is going up. When I train as a surgeon, as a liver cancer surgeon. I never saw these cases on younger population having colon cancer. We always look at the late 50s, 60s, 70s. It continued happening on them. But look at this. This is happening. Why this is happening? I think it’s difficult for to prove why I have my theories, and I think this will require another conversation, which I’m not expert, but I think it’s about what we eat. It’s the diet, I think so that plays an important role, the sugars. I think sugars are terrible and at bad. But Well, as I mentioned, that’s another topic. So cancer is increasing in the population, in the young population, and unfortunately, when we diagnose younger patients, the disease is more advanced, because we know we don’t have screening colonoscopies for patients who are this age. We were able to move it to 45 years old. The screening colonoscopies just recently, but before it was 50. So this is a population that is really affected, and hopefully we can make change. And recently, I was invited by the group of five colon cancer to go to Washington, DC for in March of this year for call for Congress. And you know that I am. A lot of you know that I’m a transplant surgeon, and I’ve been in the Senate of Albany, the capital of New York, trying to push for organ donation, for trying to increase the, you know, the sensitivity of the people to be organ donors when someone has brain dead, but that has been my only experience as a physician, trying to get into government and trying to push people from government, our congress people for moving into this but this time going to to the capital, it was, it was really impressive. It was taught you, for me, understanding being with patients, being with family, and listening to some of the politicians that are really helpful for this, independently of their party being strong, they saw it was very important and and I hope I can make more work next year, and I’m devoted to be doing this. It took me like to be three days out of work, two and a half days out of work, but I think it’s worth it, and I really enjoy and I want to continue working with them. So this was very important for me, and emotional. I want to continue doing this for for all of you. So liver metastases from colon cancer, we know that the vast majority of the liver metastases, unfortunately, are unresectable. What does that mean? That we cannot remove it with surgery. We know that surgery is the most important thing. It’s the only, only, only, and I repeat it, the only thing surgery that, at this moment, has been proved to be curative, is the only thing that can be curative, not always, but a lot of times could be curative. There hasn’t been any other thing that we can prove that could be curative. But the problem is that resectable, only 20% of these metastases are going to be resectable of the patients, and many of them are not resectable because there are multiple metastases, or the location of the metastasis in the liver, occupying some areas of the big vessels, the veins and the arteries and the bowel dogs or or the or the metastases are not responding to chemotherapy. We know that if a patient. Is not responding to chemotherapy, and we do surgery and we remove it, the chances of having recurrence early is very short, is very is very high, and the patient most likely will have recurrence very shortly, or sometimes. And I put it here in the bottom part, not an experienced surgeon or center, and that’s true, and that’s why I always ask patients to go for second or third opinions. When they come with me, I give them options. Even if they say, No, I’m comfortable with you. They said, Go. You can go with one of my colleagues here, or go outside. And I recommend people, because I want the patient to be sure of what they’re deciding. And I and sometimes there’s some centers that I have experienced that they said, You’re unresectable. They send it, they come to us, they find us, and they turn to be resectable. What happened with the patients who are unresectable and we cannot operate on them? This is not what I’m saying. This is what the literature is saying. The survival is around five to 10% at five years. What does that mean that if a patient cannot go for surgery, if 100 patients cannot go for surgery because they are unresectable, only five of them, or 10 of them, in the best case of scenario, are going to be alive at five years. So we’re talking about 90 to 95% 90% of the patients will die within those five years, perhaps of the one year, two years, three years. This is what the literature shows. And this is pretty well established and in a very high impact factor Lance, one of the highest impact factor journals when we do surgery, as I mentioned, these data coming from in 2009 from Memorial Sloan Catherine Center, where they have very good registries. This is these 60 months are five years. So to compare to the previous one that we say 5% at five years, this is around 40% at five years. So there’s a huge difference. Yes, you will say, Well, I would like to be cured. Well, you have perhaps 40% chances of being cured at five years, or maybe at 10 years, you have 25% percent, 25% chances of being cured. So most likely the cancer will come back, yes, but the thing is that we’re going to be looking very close to the cancer, and we can do other type of treatments. And this is we’re talking about resections at this moment. I’m not talking about transplantation, okay, I don’t want to mix things. This is what happened to patients.

Speaker 1 12:39
Many of the times when this is unresectable, the reason is because the remnant liver is too small. So a lot of patients come and we see that they have a lot of metastasis, perhaps in the right side of the liver and the left side is too small, or it has a small metastases. And I can say, okay, I can go and remove the left side and that little spot, and then remove the entire right side, and the patient will free of cancer. Guess what? The left side portal of the liver? Maybe it’s less than 20% of the size. So if I do that, that patient will have liver failure, and most likely patient will die. So we that will be on respectable as well, and and we know that many of the times those things happen, and there are some techniques that we can we can use, so other times, when the patient is on respectable is because of the multiple number of liver metastases. And this is where liver transplantation can play an important role. So I want to dedicate the rest of this talk about what are the outcomes of liver transplantation? What do we know about it? What is happening in North America? We know that this is started in Norway, in in the Scandinavian countries, and it has expanding faster in Europe, but there is data that I want to show about what is happening in the US, which is first time that I’m going to be showing this. I haven’t shown this data in any medical conference yet, so I’m glad that I’m going to be showing here at COLONTOWN. I mentioned to you before about the two stages hepatectomies, options that we have to do surgeries when you know, for example, in this case here, before doing transplantation, this patient, for example, has this large tumor here. So normally they will say, Okay, let’s remove the right side of the liver, and then the patient will stay with the left side, but if the left side is a small we can do a portal vein embolization. And I’m sure a lot of patients here are familiarized with this, and we can do this, we embolize the portal vein in the right side. So we put some glue and some coils here through interventional radiology, we wait around six to eight weeks. And we expect the left side of the liver, because now all the flow will come here will grow, or in this case where there are multiple we can go do surgery in the first stage. We remove the tumors in the left side of the liver. We clear the left side of the liver, which is smaller, and instead of embolizing, we can ligate will be the same effect, and then the flow will go to the left side. Will be a very similar scenario. This This one you didn’t operate. But in this one you operated. But in both, you will wait six to eight, six to eight weeks, and then the left side of the liver will grow to around 30% or more, and then you can go and operate. And that is called two stages. He protects. But what happened in this study of five US Centers, and you can see here, people from MD Anderson, people from Memorial, people from Hopkins at that moment. Tim poll, he was not in Ohio. He was in Hopkins. And these are our big centers in us, and they they were doing a lot of the two stages, hepatectomies, 16 years of data. A lot of these patients have hepatic arts in Fusion because they have a lot of tumor loads. The more than half of those patients of this have portal veneer, modelization. What happened to them? The morbidity. Morbidity means complications after the second stage was 50% so a lot of these patients have complications, expected two operations, and this is what happened, overall survival, those patients who had the two stage hepatectomy, compared to those ones who only went for chemotherapy because they couldn’t operate on them, there was a significant difference in survival. So you can see that these ones, at five years only perhaps 15% were alive, compared to almost 50% of the patients who went for the two stage patheta, means were alive. Now in this data coming from Rene Adam, you probably you know Rene Adam from Paul Bruce, very famous certain there. And this is from MD Anderson. And this is a systematic review. That means that this Dr lamb, he went and looked at the data from the MD Anderson, from Paul Bruce and from other centers. And they put all these papers together, 459 patients. And they saw that this population of patients, they survived 20% at three years. They did, sorry, not survive the disease free survival. So 80% of the patient the cancer will come back by three years. I think it’s something that is expected. Why? Because these patients had a lot of disease in the liver, and probably they have micro metastases that, as a surgeon, we cannot see and we miss them, right? The alt procedure, I think I have talked here about that is a very similar situation, but it’s quicker. It’s faster. It came here from from Germany. The Germans push this for doing this normally. There are more innovation coming from Europe. And then we start developing things here, because we have more regulations. That is complex to do things here, but they go and remove the left side of tumors. And then I gave the right portal vein, similar to what I described before, but the difference is, in the first surgery, we divide the liver completely. We divide like we open it like a book, and then the left side of the liver is small, but the right side of the liver, which has the cancer, is receiving blood supply from the artery still, so it’s alive, that portion of liver. And we went just 10 days, and in 10 days, the liver of the left side almost duplicate its size, and we go back and remove it. And with this surgery, we are able to operate more than with the two stage. He protected me. However, it’s very aggressive to do two major surgeries in 10 days of difference. And this was a case, as you can see, this is a small size. You can see there’s perhaps the CT scan is not the best, but you can see a tumor here, little two tumors here, tumor here, in the right side and the right side. And so this patient needs a hepatectomy of the right side, but the remnant liver was too small, and this is when we did Imagine we did an Alps. Look at this with the partition. It’s divided here you can see how the right side of the liver shrinks, and it’s impressive. Look at this. This is the left side. It was this part here. This looks like this patient was born with almost known left side, and now it’s huge. This was the first one that I did in my life, and I really thought this was phenomenal. And I continue doing in a very selective cases. This is one of the papers that I published where we can see that the survival of these patients with high two. Tumors we do Alps is very similar of what we saw in the two stage hepatitomies. It doesn’t change too much. Perhaps it’s around 30% that three five years of the survival and the recurrence is pretty high. We are able to operate more than the two stage hepatitis. But I think it’s just selecting the patient, because, honestly, I would do only this in a patient who is very healthy and in good performance status. Now, what happened to those patients who initially, we call them, you know, you’re unresectable. We cannot respect. We cannot use an Alps. We cannot use a two stage hepatite, a portal vein embolization. You are unresectable, so the patient just received chemotherapy, but the patient responds very well, and the patient, we call it conversion. Now we say, Oh, you responded very well. The tumors are smaller now we can go and operate. What happened to them if we operate on them and we remove the cancer, do they do the same as those patients who were initially resectable? Unfortunately, not. And the survival at five years is around 30% and around 80 to 85% of the patient, the cancer will come back five, about five years, so a little bit worse, and it’s expected. Why? Because some of the tumors that disappear, perhaps they are still there. We cannot see it in the CT scans. We cannot see them in the PET scans. We cannot see them in the MRI, but they are still there. So this is what, for example, this is a case in our in Rochester where this patient had look at these multiple metastases here in the right side and then in the left side as well. So this case was called on resectable on resectable disease. But look at this. Now, the patient received chemotherapy, and look at the response. I want you. I’m going to go back so you can see this. Look, the tumors are in the right side, multiple this one here, here, here, here, here. So clearly we do a resection. This patient won’t have it.

Speaker 1 22:17
So even here in the back part of the liver. And then the patient received chemotherapy. And you cannot see a lot of the tumors that were there. You can see this large one here, probably this one here, and even in the one that was here in the back disappear. And then you say, Oh, wow, we should go and resect. You know, maybe 10 years ago I would say, I can go and do an APR here, I can go and do an Alps in this patient, and the patient do very well. We will continue. Don’t forget about that. We’ll come back about that patient. So that is what we will call it a conversion. So what happened with those patients who has been heavily treated with chemo? Or you call it hepatic Arthur in fusion, you call it systemic chemotherapy or both. Because I know hepatic Arthur in fusion, they give both. They are never giving it alone anymore, because it was proof that it doesn’t work when you give it a loan. So in this paper, in this these are two papers, this is one and this is other one. In this paper, patients who have major treatment with a lot of chemotherapy for eight months, one year, year and a half, and then they go for a resection. 40% have major complications. When we say major complications that the patient require an intervention, a re operation for bleeding or a bile duct complication and a 10% mortality. One out of 10 of those patients die, and at five years, 13% were possible in cure. So we’re talking about that almost 90% of the patient the cancer came back in this other study of 47 patients who received more than 12 cycles. That is just six months of treatment. You know better than me about this with chemotherapy and when they went for surgery, 50% of the patient had major complications, and 20% mortality. Two out of 10 patients died. And at three years in this study, all the patients have recurrency. Cancer came back. I think they are. They did better than the patients who only received chemotherapy, definitely. But what I’m showing here is that we have to be very cautious in patients who have to have been heavily treated with chemo when we do liver receptions. And I witness of this as a search, I think some of you know I don’t do trans. Only I do a lot of reverse sections, a little bit that I want to talk about the paddy car three in fusion, because I have seen a lot of a few of these patients, I wouldn’t say like hundreds of these patients, but several of these patients will go for the particle in fusion. So in this paper, that it was probably a little bit off, because this is coming from 2007 but it was known that the hepatic artery in Fusion treatment alone, without systemic chemotherapy, is was not working. It shouldn’t be used. And they call it this the end of Panera, which is not because it’s coming back and they’re pushing and MSK is doing it, and nothing against them. I have very good relationship with them, and there were colleagues, and we have friendship communication with them, but I think we need to be cautious about this. In this study, where they did a trial of efficacy, that means how they compare hepatic artery fusion with systemic chemo. And if you can see here is these are patients. We’re not talking about surgery, we’re just talking about which one did better. Patients will receive a Patric Arthur in fusion with systemic or those ones who did systemic chemotherapy, and they were very similar in number of tumors and age of the patient, so there was no significant difference in those factors, and the only difference in survival of these patients, the patients who received only systemic chemotherapy and no surgery, they survived an average of 20 months because they were unresectable, and the patients will receive the fatty car in Fusion just four months more. Yes, there wasn’t a benefit of those ones who received hepatic art in fusion, not very impressive to see four months, and there were no survivors at five years in any of the two groups. So with that, I want to start mentioning about what’s new for unresectable liver metastas, and we call it the new kid on the block today, alright? And this, some of you are aware of this, and this is started, as I mentioned at the beginning. This is not new liver transplantation started in 2013 and and where is my friend here? PAL Dad, here it is. He’s the guy. He is the main guy. Pal dad, that his first name, his last name is like pal dad is the main surgeon. What is interesting about Norway? There’s only one center in that entire country, only one center that is doing liver transplantation in the United States. How many centers we have doing liver transplantation? Perhaps arrow, 180 maybe. Centers doing liver transplantation. It’s not socialized medicine here, over there is socialized medicine. So there’s no competition. Here is competition, right? So it’s very different. Every patient who needs a liver transplant will go to only one center in Oslo. So the the regulations and the main the way of managing things is much easier here. It’s if I want to do something different, I have 200 centers going against it’s very difficult to make progress with sometimes when we want to do something different. So they were able, and also, they have a short waiting list in their patients who have cirrhosis. They don’t have that many patients, and people donate a lot. So he said, Well, why don’t we start transplanting patients with unresectable metastasis? Because we can use this organ. So these patients, because the French surgeons in the 1990s they use those livers in patients with colorectal metastases, but the outcome was very good, but this was 30 years later, when they started using it now in Norway, and in 30 years, we have much better chemotherapy. We have much better immunotherapy for for patients who get transplant, because patients will receive transplantation require immuno suppression to medication for life to avoid rejection of the organ and and better techniques. So he started doing this, and this is what they saw. If you look at this graph, this is quite impressive. The red line is demonstrating the survival of the patients here in the bottom part is the years. So 60% of the patients who were transplanted with unresectable liver metastases were alive at five years. Wow. Even better that the patient who were resected with resectable disease since the beginning. Never seen that before. What was the problem? The problem this is recurrence. So at around two years, majority of the patient, the cancer came back, but they were alive. A lot of majority of them. So we’re going to go through that. What was happening, what was different? We. The recurrence compared when we deliver resection. I will answer that in, I think, in a couple of slides, probably. So then the Norway group, they start saying, Okay, let’s try to analyze these ones who did better. What were the main factors that created that they were doing better? And they found this as the new score. And they call it the Oslo score, if the two, if the largest metastasis is less than 5.5 centimeters, if the CEA a transplant at the moment of transplant is below 80, if the patient is not progressing on chemotherapy, and if the time from the diagnosis to the transplant is around two years. And if you have each one of these is four points and four points, the transplant will do very bad. If it’s three points, do better, two points or better, and zero to one points, all of the patients were alive. We need to be cautious as well. This is not like, Wow. Yes, this, this is impressive, but look at the number of patients. We’re talking about six patients, five patients, five patients. So we’re talking about small population of patients. So my I reviewed this paper many years ago, and when I saw that, I was really impressed. I was saying why we cannot do this in the US. Well, I was in Canada, sorry. Why? We cannot do this in Canada. It’s impressive, but, but I said, Well, we have to be cautious, because this is a small population, but this has been growing, and now the numbers are more higher and proving the same. Now this is a new thing that is happening, and here in Rochester, we’re taking consideration of this. We’re measuring this. This is the PET scans. We like to do a PET scan before transplant. And this data is showing, with a formula, we can calculate the amount of ability, abilities that the tumor takes this kind of contrast, which is

Speaker 1 32:02
the PET scan. You know, for example, here you see the the it’s highlighting here in yellow, and that’s the ability, if it’s not Avid, that means that it goes like reddish color normal. But we can quantify how much is highlighting and with this formula, if it’s below 70 centimeter cubics, it’s a good factor. If it’s above 70 it’s not a good factor, because those ones who have less than 70 centimeters cubics, they do much better. At five years, this patient has also around 80% survival. So this is a new data showing us that we can use it to verify which patients are going to do better. But it’s not always perfect. Okay. Now I mentioned to you about recurrence. What was the difference in transplant compared to liver resection, and this is so important, majority of the recurrence after transplantation, which is common, around 70% of the patient will have recurrence, but majority of them are in the lungs. But those ones who have in the lungs, they do much, much better and up in this data coming from Norway as well. At five years, all the patients were alive, they still have cancer, a lot of them, not all of them, because some of them, they were able to resect them. Those ones who have metastasis in the liver, their survival was short, but only around 5% of the patients will have recurrent in the liver. When we compare these to patients who have resection or recurrence, it’s pretty high. And I know that Dr Suarez, just a few weeks ago, presented, and he showed the data about the high recurrence after liver resection in this in patients who goes for liver section. Now this is pal that I asked permission for him to show these three lines of data, because his manuscript is under review that I think is going to be published very soon, the first study where they have the first in 2013 when they published, they continue following these patients and the five year survival, five years overall survival of 75% and 10 year, 10 year survival, 50% so we can, he can call that, if we are going to cure patients with Liver transplantation. He said that between 25 to 30% of the patients, if they are were selected, we can be curing these patients. That is pretty impressive. And to survive 75% at five years, this is something that we haven’t seen before. And as I mentioned, long recurrence. It’s very common in transplant. However, is. Is treated with curative intent. It can be resected, of course, if there’s multiple then perhaps chemotherapy will be the best option. This is data coming from the United States. This is your country, the first transplant for liver metastases in the new era, because there were old all transplants. So this is not the first one ever. Okay, no, there were other transplant that happened. Actually, Dr star saw the first Surgeon in the world that did the first liver transplant almost 50 years ago. He did colorectal metastasis liver transplant. So we’re not counting those ones. So those are the first patients who were transplanted for colorectal metastasis. This is the new era that we can call it. In this new era, the first case happened in 2017 and our programs are functioning around here, but you can see 17, 1819, how it’s increasing the interest in the in the United States. This is projection here, just with the way that is growing, and this is what’s until April here. But if we continue with the same projection, probably we will be in 30 just this year in the United States, very soon, probably one more year, we’re going to pass the numbers of Norway. But what is happening? I think what is happening. My point here is, in the United States is a lot of groups wants to do it, but they don’t have the it’s not about the surgical skills. It’s about the selection of patients and the follow up and the experience about being involved with colorectal liver metastases, because the unfortunately, here in the US, the surgical oncologist and the transplant surgeons are very separate. Where I was trained in Canada, I would do both. And I came here and I said, I only will move to Rochester if I’m able and continue doing both things. And I do liver transplant and liver sections, and we collaborate with our surgical oncologist as well, but I continue doing both things, and I think this is open opportunities for being able to to expand innovation in a lot of these spaces. If I wouldn’t be involved in both things, I wouldn’t be doing this. And why living donor? Initially, there were some centers that were using disease donor. Disease donors. I shouldn’t say this word, but I you know, because in transplant, they said that we should avoid saying cadaveric donation. But you know, when patients have brain dead, that’s the most common way of donating in the United States, the 90% of the transplants that I do are from deceased donors, someone who has brain dead our team flies go and retrieve the organ, bring it here, and we operate our patients who has cirrhosis and it’s very sick in the ICU, and hopefully we can save that patient. And we do living daughter in patients who are in the middle of the list that they don’t have too much access. For these patients, the fact that we’re doing liver transplant for those patients give us the skills for being able to deliver living donor liver transplantation in patients who have colorectal liver metastasis, because these are patients that they are not sick from the liver. They have cancer, but they are not sick to be able to be in the top of the list of liver metastases, of liver transplantation, to attract an organ, Cath, a coordinate. So that’s why the number of living donors is increasing for colorectal metastases. And last year, 80% of them of the transplants that took place in the US for colorectal metastases were done by living orders. I can tell you if I predict, well, 90% or more than 90% next year we’re going to see this line going probably around 90 or above. Now, this is the activity that I know so far, and I might be missing some centers. And this was, I think, for around three months ago. These are some of the centers that I know. They have done at least one liver transfer for colorectal metastasis. I put these hospitals bigger ones because they have been doing more. This is Houston, in Methodist. They did, I think four, but they are not doing more. Why? Because they don’t have a living donor liver transplant search, and at that moment, they were able to use some disease organs, because a lot of people around the area of fusion were not using some organs. They were saying, No, I don’t want to use this organ for my patient, because that organ is not very good. But this surgeon said it’s not that bad, and he used it, and he had probably good outcomes in those four patients and or in other patients. And. Okay, but now the allocation system in transplantation in the country change, and a lot of those organs now are going, I don’t know, to the north, so now he’s not having access. So now the only way that he can deliver transplant for these patients is with the living donor. So this is not going to grow unless here is, help me. This is San Luis, right, yes. And this Missouri, you wash you doing few of them that they have been using some calabari organ donation. Here is Cleveland, here is Rochester, here not here is Rochester. Here’s Cleveland, and here’s Pittsburgh. Those are the three other centers that has been doing a little bit more.

Speaker 1 40:44
In our experience, we have done 10 cases, which to my understanding, where the center could have been doing more. And we published with the group from Cleveland and Toronto, this paper that perhaps some of you are away. Are aware, and this is confirming the data outside Norway. It’s a short follow up, because not all of all our patients from that we we have four patients from Rochester, four patients from Cleveland, and two patients from Toronto. Not all of them has five years arrested follow up or more than three years. So we look at three years survival, but looking at this survival, looking at almost 80% of the patients were alive at three years in this patient, and 60% recurrence free survival, that means 40% of patients have recurrence. So that as a pretty similar scenario on Norway, perhaps even a little bit better. But I don’t want to be feel like so excited, because we have to wait to see a little bit more. I will show more data there, specific from Rochester. In Rochester, as I mentioned, after 2000 it was 2018 passing that we started our protocol, and this is our protocol, and I’m gonna go for HD Cal, we go for an Oslo score below two. But to be honest, this is what we have in our protocol. But when we analyze to because we’re writing a paper right now, all our patients has been one or zero, and probably that is one of the reasons that we’re having an acceptable outcomes in our patients. And this, you know, this is the ultra score that I mentioned. But to me and to our group, there are two important things here in this ultra score. I don’t think it’s necessarily to be below 80. I think it’s more important the trend, yes, below 80. Perhaps it’s a marker that the group from Norway found. But imagine if a patient goes from 80 to 40 to 20 to 10, but then it goes from 10 to 30 to 50 to 60 to 70? Is it below 80? Yes, but that’s not good. It’s going up continuously, and closer to 80. That’s something that is not going good there, and probably that trend plays a more important role than the fact that it’s below 80. And the other point is progression of disease. Progression of disease is a bad marker that we know for liver resection, if a patient received chemotherapy and is not responding and progress those patients, we know that they have very high recurrence in transplantation, probably it’s happening. Would happen the same if we translate the data from resection to transplantation, so doing a salvage transplant, probably no, no, it wouldn’t be the ideal. And there’s sometimes that is a little bit difficult to take a decision, because you cannot prove that is progression, and it might not be progression because of the when you measure the the size of the tumor, some of them could be bigger, some of them could be smaller. And then it’s difficult to call it if it’s progression or not. But in other than that, when it’s clear that a patient is progressing, I think transplantation should be avoided. So far in our institution, we have more than one quality 140 referrals. We have a dedicated navigator that is a key member of our team, and Kayla do phenomenal job trying to be in contact with all our patients, responding as soon as possible and reporting to our nurse practitioner and to our coordinators that play a very important role, and to me and we look after there’s a lot of work that we do, bringing all the images and looking at details of patients we have to review sometimes 4050, images in our tumor board. And our radiologists are tired. They say, Well, this image. Is coming from others. CD for mother center, but we review in detail all of these things. Of those, 140 patients, only 10 has rich liver transplant. Wait a moment. There are several, at least eight or more that are still in the process of potential candidates that I think they could be candidates on 24, probably. So that’s huge number, huge number. Hopefully, the eight reached that. But to be honest, probably of those eight, maybe six or five, were reached despite that, that’s still a very big number for the next six months, majority of the patients who were who didn’t reach transplant was because there was evidence of extra particle disease, disease outside the liver. Many patients were potential candidates, but developed progression during the follow up treatment. Because we follow the patients from distance, we look at the imaging device, which sometimes we have to do biopsies to prove either a positive lymph node or lung metastases. Few, probably a handful of the patients who were sent to us for transplantation turned to be resectable. And I was, Wow, really, this is resectable. So we talked to the patient said, you know you’re resectable. You want to come to register? I can do the resection, but probably I can call one of the surgeons close to you, and maybe will be easier for you to go there. If they want to come with us, they’re welcome to come and we do the resection here. But it has happened that sometimes we find that they are resectable. If you went for third or fourth opinions, which is completely okay, because the most important thing is the patient needs to feel confident that where that patient is going is going to be the right place. I think we have all the opportunities to go and say, Okay, we I can. I want to go and see four or five centers, or four or five surgeons, and then I will decide. But when you decide stick to that, that that would be the best thing, because that creates a much better management that’s my advice. This is the data of our 10 patients. This is not the paper that we published, because remember, the paper was Toronto, Cleveland and Rochester, here is only Rochester, and this is what we’re finding out. The shorter recurrence, around 70% survival at three years. So this is pretty impressive, that it was going to change most likely because our there’s new patient that has a very short follow up, only one of our patients, of our out of the tent, has died after having some recurrence. All our nine patients, the rest of the nine patients are alive. Another patient had recurrence, unfortunately, and is getting treatment with chemotherapy. Now here, this is what we’re doing. We have a trial that we’re going through that known as the patients. Doesn’t have to go through the through, through the trial, but we registry these things here because it may cause a more creates more credibility when when you publish things for this, what we found, this is what we’re working this is my research fellow, Mariana Chavez, where these are 14 cases, 10 cases from Rochester and four cases from Cleveland. I’m not showing which one is which one. And this is so interesting. These are each patient, each patient. This is a cartoon of the when they were diagnosed. The number of metastases in the first column. In the second column is the number of tumors prior to liver transplantation. This is after the patient receive a lot of treatments, RFA, so ablation, y 90, Paddy car three, in fusion, chemotherapy, surgeries, etc, etc, right? And then this is what we found when we remove the liver in pathology. And what is impressive is that 60% of these patients, 60% in in where the pets can set. There’s no cancer here. There was cancer. So the disappearing liver metastases that I’m mentioning, they were still there. I think this is the first time, because this is the first time in the history that we have the entire specimen of the liver out. Normally, when we do live resection, we live, you know, part of the liver for the patient to survive. But this is the first time that we remove entire and we can analyze entire liver, and this is what is happening. We’re finding, clearly, with all the evidence that there was still cancer, there are 60% of time even that it’s disappear. It does not

Speaker 1 50:02
some tips and tricks that we have learned. And this is when I go to give a talk. I think I spend a lot of time with the surgeons talking about this, because they want to learn more about this, the timing from colon resection, because a lot of the patients come okay, I still have the primary side. Can I go for a transplant? Well, yes, you can go for transplant, but we have to remove the primary at some moment, or the patient goes, Hey, my colon cancer is gone. They cannot see it. What is the evidence if we go and do a liver transplant and we don’t touch the colon? I haven’t done that, but I wouldn’t, I. Am sure if we give immuno suppression, there might be some cancer cells in the colon, you will come back. So we have pushed for removing it. There’s one patient that I know that we could transplant that we remove a portion of the column for it was tattoo the cancer, and there was no cancer. But there were other two that apparently disappeared, and when we removed the portion of colon, there was still cancer, so it’s better to remove it, and we don’t want to do experimentation here in large lymph nodes. That’s a big question. What should we do? So we use endoscopic ultrasound, sometimes through the stomach, to be able to biopsy the lymph node to be sure if that’s a positively if not. If it’s a positive lymph node, it’s not a good prognosis. And we use Final aspiration, or sometimes the interventional radiologists use percutaneous biopsy. Or few times we do a laparotomy. We have to Okay. If everything looks good, but we have high suspicious we open the abdomen of the patient before or the day of the patient is coming from outside, let’s say if the patient is coming from far away from, I don’t know, Kansas City and the patient and the donor here, but we have suspicion of that. We start the operation with a recipient. Normally, we start with the donor. Normally, that’s when there’s a donor, a living donor. We start with the donor, and then we bring the recipient to the operating room. But in these situations, we don’t want to put the risk of the donor if we are not sure if we can transplant the patient, so we start with the recipient. We open, we take a biopsy of the lymph nodes there. If it’s negative, then we do, we do the transplant. If not, we have to stop the transplant. Long nodules. We have to review the two more board these what they are very dedicated, and that I’m proud of my team, that they review every single thing, and our coordinators take notes about this so and this is on top of their normal work with all the cirrhotic patients, because I’ve been able to have, in my case, a lot of resources from the department of surgery and the institution to be able to set up a team dedicated for this. But a lot of the other coordinators who are not fully involved with these, are very supportive of all of these. We talk about immuno suppression. We try to bring it down as soon as possible. We have learned more about immuno suppression because we have been trying to change some patients that probably they don’t tolerate it very well when we try to switch them. And we’re learning a lot of those things. And this, I think, a new area that I call it HEPA oncology. We have hepatologies. We follow that follows liver transplant patients, and we have oncologists that follow the patients with cancer. This is putting both things together. Our hepatologist with oncology, and I personally call it our hepato oncologist, and this is what we’re trying to develop here. I think, what time is it? Okay? I’m Hurry up. Betsy. I’m sorry for the same criteria for recipients with the Paducah pump. Just 111, more. Note about the Patriot pump. We have the same criteria for as you can see, the patient is a candidate for transplant after the pump. However, it’s very clear to tell the patient there’s a way higher risk in the transplant. Why the pad three pump creates, unfortunately, damage in the paddy Carter. You cannot use it for transplant. And without the paddy car three, deliver one work. So we need to bring the artery of the spleen, or put a conduit from the aorta from a cabaret daughter. We call it graft or conduit, the portal vein, a lot of the times, is very inflamed because of the pump, and also because of the chemotherapy of the pump in that area, and, you know, a lot of the patients capillary damage. So the risk of transplantation is way higher. We do it, but it’s way higher. The only thing that I see for me is, I think there’s a place for the palm a place for transplant. I don’t think it’s a five more, but what I would say more is, if a patient is responding to systemic chemotherapy, why changing the game? If the patient could be a transparent candidate, continue for one year, complete the year, and probably the patient will be a transplant candidate, if the patient is progressing on systemic chemotherapy, okay, the patient is not going. To be a transplant candidate. Let’s give the pump, right? And if it comes back to conversion and respondents, they doing well and well, then find surgeons who want to play hard ball and do this transplant. But if not, I wouldn’t change them the positions here, I think I will stop here. These are the areas where I think the patients are probably four areas that I call it transplant, transplant categories, those patients who we see these since the beginning were unresectable, and they still have the primary inside you, patients who have multiple metastases, but they have multiple treatments, surgeries, ablation, pump, etc, etc. And I call it more burnout, cancer burnout, liver patients who are unresectable because they have recurrence, and probably this is an area where it’s going to be extending those ones who were unresectable and converted to resectable. Perhaps transplantation will benefit this patient. And to finalize, I told you about this patient, right? Look at these metastases, this patient, and then this patient responded. And some surgeons say I can resect that, the patient decided, and we did a liver transplant because we were sure there were more metastasis. Sorry to show you this, but this is the liver. And look at the metastasis. This is the left side of the liver. Should, sorry to show you these, but 12345, here. This is the left side which I’m showing it here. 123, and this is proven that there’s cancer here. So we would do a right hepatectomy for that patient that here, they said, Let’s do a right hepatectomy only to remove this part. We will be removing this part. We will live in all these cancer. So I think we did the correct thing. This is another patient. Look at this amount of disease. Of course, this is unresectable, and this is the amazing the same patient, I promise you. It’s impressive. The response that the patient had. Look at this amazing patient came here for transplantation. This is their lovely donor. We remove the right side of the liver, a beautiful left side of a liver, enough for the donor. And this is the right side of a liver where we use it for reconstructing it. And you can see here, once the blood came into the new liver of the of the recipient, and it looks pink and beautiful. I know probably you don’t feel that this is beautiful, but it is, and this is what we find in the explant. The pathologist look at these spots of cancer. It’s suppose that here it almost disappeared minimal disease. But when we go and see in the pathology multiple spots of cancer, they’re still there. That’s what I want to show you. Another case. Look at lost those liver metastases. Patient responded so well, you can see these calcifications. And, you know, I, I’m part of these. So if, if you would bring me this patient when I was in Canada, when I didn’t have an idea that we were I was going to be doing liver transplantation, I will take this patient to the operating room and try to do resection or Alps, or two stage protections or something. We did a liver transplant, and there were multiple metastases still in the liver, as you can see here, 234567, here in the back of the liver, we’re taking a lot of this tissue as well, with the consent of our patients, that we consent them into my lab, and because we’re trying to analyze more of the biopsies to understand more about the immune system that is playing a role in this cancer, to hopefully, in the future, being able to find markers and decide which patients are going to respond better. And in conclusions, surgery is the goal in metastatic colorectal cancer and surgery, I include transplantation. There are favorable results with chemotherapy, and we have gone far away, and that’s what is helping us for being able to do liver resections more aggressively. Patients should have the opinion of different treatments modalities to explore second and third opinions. I think the field of liver transplantation is evolving quickly, and we need to be cautious about this. I don’t I hope not a lot of surgeons taking us the new thing, the new toy, and not selecting the patients correctly, the multidisciplinary team, the experience, is very important, and we should keep fighting and moving forward. These are frequently asked questions, but probably the people I would like really that people ask questions and feel comfortable to open your your camera, your screen, ask questions. There are no dumb questions. There are important questions, and I’m here for you, and thank you for this invitation. Again. You.

Betsy Post 0:00
Alrighty. So welcome. Welcome everyone. I’m Betsy post. I’m with COLONTOWN, and I’m helping facilitate this evening’s presentation with Dr Hernandez. And I also have, of course, our esteemed Mayor Lindsey and one of the folks on the cabinet with me, Julie, who are also running tech support, you know, kind of any assistance that you might need, you can definitely ping Julie Lindsey myself. I will try to help in any way. We’re not technical experts, but we’ll, we’ll do our best. But I’m going to introduce our esteemed speaker, Dr Hernandez, if you’re familiar with COLONTOWN liver lovers, Lane transplantation station, our various groups dedicated to liver Mets within the COLONTOWN community. I know that he is not someone that’s a stranger to anyone here, so we’re really honored and really thankful to have him with us this evening to talk to us about the new kid on the block, liver transplant for metastatic colorectal cancer and why that’s taking off. So just a little bit of background about Dr Hernandez and I have Julie go to the next slide. I’m not going to read to everyone, but this will be available in the recording as well. But he is the chief of the Division of transplantation at the University of Rochester Medical Center. Before that, he was in Canada. He has an amazing background and did extensive training and live liver donor transplantation in Japan. It’s really impressive. He has over 110 he probably knows the specific number peer review publications in liver transplantation and other hepatobiliary topics, and he’s on the editorial board of this esteemed Journal of surgery. So we’re super excited, again, flattered to have him here. There’s no one I think that knows more, I guess, arguably, in my opinion, about this topic of liver Mets for metastatic colorectal cancer than Doctor Hernandez, just a couple of housekeeping things, kind of in the in the middle, if you will. We do want to take your questions, so it’s really important that we keep this, you know, interactive. I would request that you please put the questions in chat. So we are going to monitor chat, and we are going to come back to it after the presentation and go back to those questions. We really want to try to answer every question that everyone has. So please put those in chat so that we can go through them. We’re again going to really monitor those, look at them, make sure that we do go back and ask all of those questions. So please put those in chat, and if you have any questions about how to do that, you can ping one of us will try to help you. So, Julie, you can go to the next slide. And so thank you guys so much for being here, and I’m going to turn it over to Dr Hernandez to start the presentation again. Please put the questions in chat. Say hello and chat. If there’s anything that you hear that you have questions about or you think is interesting, put it in chat. So we’re going to be monitoring that, and we’re all happy to have you here tonight, so take it away. Dr Hernandez,

Speaker 1 3:17
thank you, Betsy. Thank you Lincy, thank you, Claire, for this invitation. It’s always a pleasure to be in this group and to be part of it, once in a while, to be able to participate and guide patients I have dedicated the last many years of my career, a lot into this field of liver metastases, and I’m very happy and glad that we have been able to make progress in science, in medicine and surgery, and always try to push a little bit more the envelope to help more patients. And I like the title that it was assigned, that the new kid on the block. And I tried to find, I remember when I was younger, the New Kids on the Block. So I find this picture of them when they are 2022 they look a little bit older. They’re not kids anymore. And I think that’s exactly what happened to liver transplantation for colorectal metastasis. Is not a new kid, really. It’s new for a lot of us, but it already exists there for many years. So with this, I’m going to start. And last time, I don’t know how long ago was that, but probably a year or something like that, that I was invited by COLONTOWN to give a presentation, and I expanded a lot about colorectal liver metastasis, and then I talked about liver transplantation. Today, I want to concentrate much more in liver transplantation, but to being able to show the importance or why liver transplantation might play, or play a very important role, I want to talk. Back again, a little bit about all the background of colorectal liver metastases. With this, I want to show the this first slide, showing that you all know that is the third most common cancer. Colon cancer is the third more common cancer in the world, after prostate and breast cancer. So it’s not uncommon to have people like you or your beloved that has colon cancer, unfortunately, and it’s so common. But the good thing is that we make a lot of advancements in treatment, especially in chemotherapy, I would say, in the last 20 years. But unfortunately, there hasn’t been anything that is huge over the last 15 years for colorectal liver metastasis. We’re starting to do some changes, and I’m looking forward to, hopefully, within five to 10 years to be able to to have much more and more. But this slide is showing you impressively how colon cancer is increasing in these young population did from 20s, 30s and 40s. Look at the green part is showing how it’s increasing being the number of cases on this population is going up. When I train as a surgeon, as a liver cancer surgeon. I never saw these cases on younger population having colon cancer. We always look at the late 50s, 60s, 70s. It continued happening on them. But look at this. This is happening. Why this is happening? I think it’s difficult for to prove why I have my theories, and I think this will require another conversation, which I’m not expert, but I think it’s about what we eat. It’s the diet, I think so that plays an important role, the sugars. I think sugars are terrible and at bad. But Well, as I mentioned, that’s another topic. So cancer is increasing in the population, in the young population, and unfortunately, when we diagnose younger patients, the disease is more advanced, because we know we don’t have screening colonoscopies for patients who are this age. We were able to move it to 45 years old. The screening colonoscopies just recently, but before it was 50. So this is a population that is really affected, and hopefully we can make change. And recently, I was invited by the group of five colon cancer to go to Washington, DC for in March of this year for call for Congress. And you know that I am. A lot of you know that I’m a transplant surgeon, and I’ve been in the Senate of Albany, the capital of New York, trying to push for organ donation, for trying to increase the, you know, the sensitivity of the people to be organ donors when someone has brain dead, but that has been my only experience as a physician, trying to get into government and trying to push people from government, our congress people for moving into this but this time going to to the capital, it was, it was really impressive. It was taught you, for me, understanding being with patients, being with family, and listening to some of the politicians that are really helpful for this, independently of their party being strong, they saw it was very important and and I hope I can make more work next year, and I’m devoted to be doing this. It took me like to be three days out of work, two and a half days out of work, but I think it’s worth it, and I really enjoy and I want to continue working with them. So this was very important for me, and emotional. I want to continue doing this for for all of you. So liver metastases from colon cancer, we know that the vast majority of the liver metastases, unfortunately, are unresectable. What does that mean? That we cannot remove it with surgery. We know that surgery is the most important thing. It’s the only, only, only, and I repeat it, the only thing surgery that, at this moment, has been proved to be curative, is the only thing that can be curative, not always, but a lot of times could be curative. There hasn’t been any other thing that we can prove that could be curative. But the problem is that resectable, only 20% of these metastases are going to be resectable of the patients, and many of them are not resectable because there are multiple metastases, or the location of the metastasis in the liver, occupying some areas of the big vessels, the veins and the arteries and the bowel dogs or or the or the metastases are not responding to chemotherapy. We know that if a patient. Is not responding to chemotherapy, and we do surgery and we remove it, the chances of having recurrence early is very short, is very is very high, and the patient most likely will have recurrence very shortly, or sometimes. And I put it here in the bottom part, not an experienced surgeon or center, and that’s true, and that’s why I always ask patients to go for second or third opinions. When they come with me, I give them options. Even if they say, No, I’m comfortable with you. They said, Go. You can go with one of my colleagues here, or go outside. And I recommend people, because I want the patient to be sure of what they’re deciding. And I and sometimes there’s some centers that I have experienced that they said, You’re unresectable. They send it, they come to us, they find us, and they turn to be resectable. What happened with the patients who are unresectable and we cannot operate on them? This is not what I’m saying. This is what the literature is saying. The survival is around five to 10% at five years. What does that mean that if a patient cannot go for surgery, if 100 patients cannot go for surgery because they are unresectable, only five of them, or 10 of them, in the best case of scenario, are going to be alive at five years. So we’re talking about 90 to 95% 90% of the patients will die within those five years, perhaps of the one year, two years, three years. This is what the literature shows. And this is pretty well established and in a very high impact factor Lance, one of the highest impact factor journals when we do surgery, as I mentioned, these data coming from in 2009 from Memorial Sloan Catherine Center, where they have very good registries. This is these 60 months are five years. So to compare to the previous one that we say 5% at five years, this is around 40% at five years. So there’s a huge difference. Yes, you will say, Well, I would like to be cured. Well, you have perhaps 40% chances of being cured at five years, or maybe at 10 years, you have 25% percent, 25% chances of being cured. So most likely the cancer will come back, yes, but the thing is that we’re going to be looking very close to the cancer, and we can do other type of treatments. And this is we’re talking about resections at this moment. I’m not talking about transplantation, okay, I don’t want to mix things. This is what happened to patients.

Speaker 1 12:39
Many of the times when this is unresectable, the reason is because the remnant liver is too small. So a lot of patients come and we see that they have a lot of metastasis, perhaps in the right side of the liver and the left side is too small, or it has a small metastases. And I can say, okay, I can go and remove the left side and that little spot, and then remove the entire right side, and the patient will free of cancer. Guess what? The left side portal of the liver? Maybe it’s less than 20% of the size. So if I do that, that patient will have liver failure, and most likely patient will die. So we that will be on respectable as well, and and we know that many of the times those things happen, and there are some techniques that we can we can use, so other times, when the patient is on respectable is because of the multiple number of liver metastases. And this is where liver transplantation can play an important role. So I want to dedicate the rest of this talk about what are the outcomes of liver transplantation? What do we know about it? What is happening in North America? We know that this is started in Norway, in in the Scandinavian countries, and it has expanding faster in Europe, but there is data that I want to show about what is happening in the US, which is first time that I’m going to be showing this. I haven’t shown this data in any medical conference yet, so I’m glad that I’m going to be showing here at COLONTOWN. I mentioned to you before about the two stages hepatectomies, options that we have to do surgeries when you know, for example, in this case here, before doing transplantation, this patient, for example, has this large tumor here. So normally they will say, Okay, let’s remove the right side of the liver, and then the patient will stay with the left side, but if the left side is a small we can do a portal vein embolization. And I’m sure a lot of patients here are familiarized with this, and we can do this, we embolize the portal vein in the right side. So we put some glue and some coils here through interventional radiology, we wait around six to eight weeks. And we expect the left side of the liver, because now all the flow will come here will grow, or in this case where there are multiple we can go do surgery in the first stage. We remove the tumors in the left side of the liver. We clear the left side of the liver, which is smaller, and instead of embolizing, we can ligate will be the same effect, and then the flow will go to the left side. Will be a very similar scenario. This This one you didn’t operate. But in this one you operated. But in both, you will wait six to eight, six to eight weeks, and then the left side of the liver will grow to around 30% or more, and then you can go and operate. And that is called two stages. He protects. But what happened in this study of five US Centers, and you can see here, people from MD Anderson, people from Memorial, people from Hopkins at that moment. Tim poll, he was not in Ohio. He was in Hopkins. And these are our big centers in us, and they they were doing a lot of the two stages, hepatectomies, 16 years of data. A lot of these patients have hepatic arts in Fusion because they have a lot of tumor loads. The more than half of those patients of this have portal veneer, modelization. What happened to them? The morbidity. Morbidity means complications after the second stage was 50% so a lot of these patients have complications, expected two operations, and this is what happened, overall survival, those patients who had the two stage hepatectomy, compared to those ones who only went for chemotherapy because they couldn’t operate on them, there was a significant difference in survival. So you can see that these ones, at five years only perhaps 15% were alive, compared to almost 50% of the patients who went for the two stage patheta, means were alive. Now in this data coming from Rene Adam, you probably you know Rene Adam from Paul Bruce, very famous certain there. And this is from MD Anderson. And this is a systematic review. That means that this Dr lamb, he went and looked at the data from the MD Anderson, from Paul Bruce and from other centers. And they put all these papers together, 459 patients. And they saw that this population of patients, they survived 20% at three years. They did, sorry, not survive the disease free survival. So 80% of the patient the cancer will come back by three years. I think it’s something that is expected. Why? Because these patients had a lot of disease in the liver, and probably they have micro metastases that, as a surgeon, we cannot see and we miss them, right? The alt procedure, I think I have talked here about that is a very similar situation, but it’s quicker. It’s faster. It came here from from Germany. The Germans push this for doing this normally. There are more innovation coming from Europe. And then we start developing things here, because we have more regulations. That is complex to do things here, but they go and remove the left side of tumors. And then I gave the right portal vein, similar to what I described before, but the difference is, in the first surgery, we divide the liver completely. We divide like we open it like a book, and then the left side of the liver is small, but the right side of the liver, which has the cancer, is receiving blood supply from the artery still, so it’s alive, that portion of liver. And we went just 10 days, and in 10 days, the liver of the left side almost duplicate its size, and we go back and remove it. And with this surgery, we are able to operate more than with the two stage. He protected me. However, it’s very aggressive to do two major surgeries in 10 days of difference. And this was a case, as you can see, this is a small size. You can see there’s perhaps the CT scan is not the best, but you can see a tumor here, little two tumors here, tumor here, in the right side and the right side. And so this patient needs a hepatectomy of the right side, but the remnant liver was too small, and this is when we did Imagine we did an Alps. Look at this with the partition. It’s divided here you can see how the right side of the liver shrinks, and it’s impressive. Look at this. This is the left side. It was this part here. This looks like this patient was born with almost known left side, and now it’s huge. This was the first one that I did in my life, and I really thought this was phenomenal. And I continue doing in a very selective cases. This is one of the papers that I published where we can see that the survival of these patients with high two. Tumors we do Alps is very similar of what we saw in the two stage hepatitomies. It doesn’t change too much. Perhaps it’s around 30% that three five years of the survival and the recurrence is pretty high. We are able to operate more than the two stage hepatitis. But I think it’s just selecting the patient, because, honestly, I would do only this in a patient who is very healthy and in good performance status. Now, what happened to those patients who initially, we call them, you know, you’re unresectable. We cannot respect. We cannot use an Alps. We cannot use a two stage hepatite, a portal vein embolization. You are unresectable, so the patient just received chemotherapy, but the patient responds very well, and the patient, we call it conversion. Now we say, Oh, you responded very well. The tumors are smaller now we can go and operate. What happened to them if we operate on them and we remove the cancer, do they do the same as those patients who were initially resectable? Unfortunately, not. And the survival at five years is around 30% and around 80 to 85% of the patient, the cancer will come back five, about five years, so a little bit worse, and it’s expected. Why? Because some of the tumors that disappear, perhaps they are still there. We cannot see it in the CT scans. We cannot see them in the PET scans. We cannot see them in the MRI, but they are still there. So this is what, for example, this is a case in our in Rochester where this patient had look at these multiple metastases here in the right side and then in the left side as well. So this case was called on resectable on resectable disease. But look at this. Now, the patient received chemotherapy, and look at the response. I want you. I’m going to go back so you can see this. Look, the tumors are in the right side, multiple this one here, here, here, here, here. So clearly we do a resection. This patient won’t have it.

Speaker 1 22:17
So even here in the back part of the liver. And then the patient received chemotherapy. And you cannot see a lot of the tumors that were there. You can see this large one here, probably this one here, and even in the one that was here in the back disappear. And then you say, Oh, wow, we should go and resect. You know, maybe 10 years ago I would say, I can go and do an APR here, I can go and do an Alps in this patient, and the patient do very well. We will continue. Don’t forget about that. We’ll come back about that patient. So that is what we will call it a conversion. So what happened with those patients who has been heavily treated with chemo? Or you call it hepatic Arthur in fusion, you call it systemic chemotherapy or both. Because I know hepatic Arthur in fusion, they give both. They are never giving it alone anymore, because it was proof that it doesn’t work when you give it a loan. So in this paper, in this these are two papers, this is one and this is other one. In this paper, patients who have major treatment with a lot of chemotherapy for eight months, one year, year and a half, and then they go for a resection. 40% have major complications. When we say major complications that the patient require an intervention, a re operation for bleeding or a bile duct complication and a 10% mortality. One out of 10 of those patients die, and at five years, 13% were possible in cure. So we’re talking about that almost 90% of the patient the cancer came back in this other study of 47 patients who received more than 12 cycles. That is just six months of treatment. You know better than me about this with chemotherapy and when they went for surgery, 50% of the patient had major complications, and 20% mortality. Two out of 10 patients died. And at three years in this study, all the patients have recurrency. Cancer came back. I think they are. They did better than the patients who only received chemotherapy, definitely. But what I’m showing here is that we have to be very cautious in patients who have to have been heavily treated with chemo when we do liver receptions. And I witness of this as a search, I think some of you know I don’t do trans. Only I do a lot of reverse sections, a little bit that I want to talk about the paddy car three in fusion, because I have seen a lot of a few of these patients, I wouldn’t say like hundreds of these patients, but several of these patients will go for the particle in fusion. So in this paper, that it was probably a little bit off, because this is coming from 2007 but it was known that the hepatic artery in Fusion treatment alone, without systemic chemotherapy, is was not working. It shouldn’t be used. And they call it this the end of Panera, which is not because it’s coming back and they’re pushing and MSK is doing it, and nothing against them. I have very good relationship with them, and there were colleagues, and we have friendship communication with them, but I think we need to be cautious about this. In this study, where they did a trial of efficacy, that means how they compare hepatic artery fusion with systemic chemo. And if you can see here is these are patients. We’re not talking about surgery, we’re just talking about which one did better. Patients will receive a Patric Arthur in fusion with systemic or those ones who did systemic chemotherapy, and they were very similar in number of tumors and age of the patient, so there was no significant difference in those factors, and the only difference in survival of these patients, the patients who received only systemic chemotherapy and no surgery, they survived an average of 20 months because they were unresectable, and the patients will receive the fatty car in Fusion just four months more. Yes, there wasn’t a benefit of those ones who received hepatic art in fusion, not very impressive to see four months, and there were no survivors at five years in any of the two groups. So with that, I want to start mentioning about what’s new for unresectable liver metastas, and we call it the new kid on the block today, alright? And this, some of you are aware of this, and this is started, as I mentioned at the beginning. This is not new liver transplantation started in 2013 and and where is my friend here? PAL Dad, here it is. He’s the guy. He is the main guy. Pal dad, that his first name, his last name is like pal dad is the main surgeon. What is interesting about Norway? There’s only one center in that entire country, only one center that is doing liver transplantation in the United States. How many centers we have doing liver transplantation? Perhaps arrow, 180 maybe. Centers doing liver transplantation. It’s not socialized medicine here, over there is socialized medicine. So there’s no competition. Here is competition, right? So it’s very different. Every patient who needs a liver transplant will go to only one center in Oslo. So the the regulations and the main the way of managing things is much easier here. It’s if I want to do something different, I have 200 centers going against it’s very difficult to make progress with sometimes when we want to do something different. So they were able, and also, they have a short waiting list in their patients who have cirrhosis. They don’t have that many patients, and people donate a lot. So he said, Well, why don’t we start transplanting patients with unresectable metastasis? Because we can use this organ. So these patients, because the French surgeons in the 1990s they use those livers in patients with colorectal metastases, but the outcome was very good, but this was 30 years later, when they started using it now in Norway, and in 30 years, we have much better chemotherapy. We have much better immunotherapy for for patients who get transplant, because patients will receive transplantation require immuno suppression to medication for life to avoid rejection of the organ and and better techniques. So he started doing this, and this is what they saw. If you look at this graph, this is quite impressive. The red line is demonstrating the survival of the patients here in the bottom part is the years. So 60% of the patients who were transplanted with unresectable liver metastases were alive at five years. Wow. Even better that the patient who were resected with resectable disease since the beginning. Never seen that before. What was the problem? The problem this is recurrence. So at around two years, majority of the patient, the cancer came back, but they were alive. A lot of majority of them. So we’re going to go through that. What was happening, what was different? We. The recurrence compared when we deliver resection. I will answer that in, I think, in a couple of slides, probably. So then the Norway group, they start saying, Okay, let’s try to analyze these ones who did better. What were the main factors that created that they were doing better? And they found this as the new score. And they call it the Oslo score, if the two, if the largest metastasis is less than 5.5 centimeters, if the CEA a transplant at the moment of transplant is below 80, if the patient is not progressing on chemotherapy, and if the time from the diagnosis to the transplant is around two years. And if you have each one of these is four points and four points, the transplant will do very bad. If it’s three points, do better, two points or better, and zero to one points, all of the patients were alive. We need to be cautious as well. This is not like, Wow. Yes, this, this is impressive, but look at the number of patients. We’re talking about six patients, five patients, five patients. So we’re talking about small population of patients. So my I reviewed this paper many years ago, and when I saw that, I was really impressed. I was saying why we cannot do this in the US. Well, I was in Canada, sorry. Why? We cannot do this in Canada. It’s impressive, but, but I said, Well, we have to be cautious, because this is a small population, but this has been growing, and now the numbers are more higher and proving the same. Now this is a new thing that is happening, and here in Rochester, we’re taking consideration of this. We’re measuring this. This is the PET scans. We like to do a PET scan before transplant. And this data is showing, with a formula, we can calculate the amount of ability, abilities that the tumor takes this kind of contrast, which is

Speaker 1 32:02
the PET scan. You know, for example, here you see the the it’s highlighting here in yellow, and that’s the ability, if it’s not Avid, that means that it goes like reddish color normal. But we can quantify how much is highlighting and with this formula, if it’s below 70 centimeter cubics, it’s a good factor. If it’s above 70 it’s not a good factor, because those ones who have less than 70 centimeters cubics, they do much better. At five years, this patient has also around 80% survival. So this is a new data showing us that we can use it to verify which patients are going to do better. But it’s not always perfect. Okay. Now I mentioned to you about recurrence. What was the difference in transplant compared to liver resection, and this is so important, majority of the recurrence after transplantation, which is common, around 70% of the patient will have recurrence, but majority of them are in the lungs. But those ones who have in the lungs, they do much, much better and up in this data coming from Norway as well. At five years, all the patients were alive, they still have cancer, a lot of them, not all of them, because some of them, they were able to resect them. Those ones who have metastasis in the liver, their survival was short, but only around 5% of the patients will have recurrent in the liver. When we compare these to patients who have resection or recurrence, it’s pretty high. And I know that Dr Suarez, just a few weeks ago, presented, and he showed the data about the high recurrence after liver resection in this in patients who goes for liver section. Now this is pal that I asked permission for him to show these three lines of data, because his manuscript is under review that I think is going to be published very soon, the first study where they have the first in 2013 when they published, they continue following these patients and the five year survival, five years overall survival of 75% and 10 year, 10 year survival, 50% so we can, he can call that, if we are going to cure patients with Liver transplantation. He said that between 25 to 30% of the patients, if they are were selected, we can be curing these patients. That is pretty impressive. And to survive 75% at five years, this is something that we haven’t seen before. And as I mentioned, long recurrence. It’s very common in transplant. However, is. Is treated with curative intent. It can be resected, of course, if there’s multiple then perhaps chemotherapy will be the best option. This is data coming from the United States. This is your country, the first transplant for liver metastases in the new era, because there were old all transplants. So this is not the first one ever. Okay, no, there were other transplant that happened. Actually, Dr star saw the first Surgeon in the world that did the first liver transplant almost 50 years ago. He did colorectal metastasis liver transplant. So we’re not counting those ones. So those are the first patients who were transplanted for colorectal metastasis. This is the new era that we can call it. In this new era, the first case happened in 2017 and our programs are functioning around here, but you can see 17, 1819, how it’s increasing the interest in the in the United States. This is projection here, just with the way that is growing, and this is what’s until April here. But if we continue with the same projection, probably we will be in 30 just this year in the United States, very soon, probably one more year, we’re going to pass the numbers of Norway. But what is happening? I think what is happening. My point here is, in the United States is a lot of groups wants to do it, but they don’t have the it’s not about the surgical skills. It’s about the selection of patients and the follow up and the experience about being involved with colorectal liver metastases, because the unfortunately, here in the US, the surgical oncologist and the transplant surgeons are very separate. Where I was trained in Canada, I would do both. And I came here and I said, I only will move to Rochester if I’m able and continue doing both things. And I do liver transplant and liver sections, and we collaborate with our surgical oncologist as well, but I continue doing both things, and I think this is open opportunities for being able to to expand innovation in a lot of these spaces. If I wouldn’t be involved in both things, I wouldn’t be doing this. And why living donor? Initially, there were some centers that were using disease donor. Disease donors. I shouldn’t say this word, but I you know, because in transplant, they said that we should avoid saying cadaveric donation. But you know, when patients have brain dead, that’s the most common way of donating in the United States, the 90% of the transplants that I do are from deceased donors, someone who has brain dead our team flies go and retrieve the organ, bring it here, and we operate our patients who has cirrhosis and it’s very sick in the ICU, and hopefully we can save that patient. And we do living daughter in patients who are in the middle of the list that they don’t have too much access. For these patients, the fact that we’re doing liver transplant for those patients give us the skills for being able to deliver living donor liver transplantation in patients who have colorectal liver metastasis, because these are patients that they are not sick from the liver. They have cancer, but they are not sick to be able to be in the top of the list of liver metastases, of liver transplantation, to attract an organ, Cath, a coordinate. So that’s why the number of living donors is increasing for colorectal metastases. And last year, 80% of them of the transplants that took place in the US for colorectal metastases were done by living orders. I can tell you if I predict, well, 90% or more than 90% next year we’re going to see this line going probably around 90 or above. Now, this is the activity that I know so far, and I might be missing some centers. And this was, I think, for around three months ago. These are some of the centers that I know. They have done at least one liver transfer for colorectal metastasis. I put these hospitals bigger ones because they have been doing more. This is Houston, in Methodist. They did, I think four, but they are not doing more. Why? Because they don’t have a living donor liver transplant search, and at that moment, they were able to use some disease organs, because a lot of people around the area of fusion were not using some organs. They were saying, No, I don’t want to use this organ for my patient, because that organ is not very good. But this surgeon said it’s not that bad, and he used it, and he had probably good outcomes in those four patients and or in other patients. And. Okay, but now the allocation system in transplantation in the country change, and a lot of those organs now are going, I don’t know, to the north, so now he’s not having access. So now the only way that he can deliver transplant for these patients is with the living donor. So this is not going to grow unless here is, help me. This is San Luis, right, yes. And this Missouri, you wash you doing few of them that they have been using some calabari organ donation. Here is Cleveland, here is Rochester, here not here is Rochester. Here’s Cleveland, and here’s Pittsburgh. Those are the three other centers that has been doing a little bit more.

Speaker 1 40:44
In our experience, we have done 10 cases, which to my understanding, where the center could have been doing more. And we published with the group from Cleveland and Toronto, this paper that perhaps some of you are away. Are aware, and this is confirming the data outside Norway. It’s a short follow up, because not all of all our patients from that we we have four patients from Rochester, four patients from Cleveland, and two patients from Toronto. Not all of them has five years arrested follow up or more than three years. So we look at three years survival, but looking at this survival, looking at almost 80% of the patients were alive at three years in this patient, and 60% recurrence free survival, that means 40% of patients have recurrence. So that as a pretty similar scenario on Norway, perhaps even a little bit better. But I don’t want to be feel like so excited, because we have to wait to see a little bit more. I will show more data there, specific from Rochester. In Rochester, as I mentioned, after 2000 it was 2018 passing that we started our protocol, and this is our protocol, and I’m gonna go for HD Cal, we go for an Oslo score below two. But to be honest, this is what we have in our protocol. But when we analyze to because we’re writing a paper right now, all our patients has been one or zero, and probably that is one of the reasons that we’re having an acceptable outcomes in our patients. And this, you know, this is the ultra score that I mentioned. But to me and to our group, there are two important things here in this ultra score. I don’t think it’s necessarily to be below 80. I think it’s more important the trend, yes, below 80. Perhaps it’s a marker that the group from Norway found. But imagine if a patient goes from 80 to 40 to 20 to 10, but then it goes from 10 to 30 to 50 to 60 to 70? Is it below 80? Yes, but that’s not good. It’s going up continuously, and closer to 80. That’s something that is not going good there, and probably that trend plays a more important role than the fact that it’s below 80. And the other point is progression of disease. Progression of disease is a bad marker that we know for liver resection, if a patient received chemotherapy and is not responding and progress those patients, we know that they have very high recurrence in transplantation, probably it’s happening. Would happen the same if we translate the data from resection to transplantation, so doing a salvage transplant, probably no, no, it wouldn’t be the ideal. And there’s sometimes that is a little bit difficult to take a decision, because you cannot prove that is progression, and it might not be progression because of the when you measure the the size of the tumor, some of them could be bigger, some of them could be smaller. And then it’s difficult to call it if it’s progression or not. But in other than that, when it’s clear that a patient is progressing, I think transplantation should be avoided. So far in our institution, we have more than one quality 140 referrals. We have a dedicated navigator that is a key member of our team, and Kayla do phenomenal job trying to be in contact with all our patients, responding as soon as possible and reporting to our nurse practitioner and to our coordinators that play a very important role, and to me and we look after there’s a lot of work that we do, bringing all the images and looking at details of patients we have to review sometimes 4050, images in our tumor board. And our radiologists are tired. They say, Well, this image. Is coming from others. CD for mother center, but we review in detail all of these things. Of those, 140 patients, only 10 has rich liver transplant. Wait a moment. There are several, at least eight or more that are still in the process of potential candidates that I think they could be candidates on 24, probably. So that’s huge number, huge number. Hopefully, the eight reached that. But to be honest, probably of those eight, maybe six or five, were reached despite that, that’s still a very big number for the next six months, majority of the patients who were who didn’t reach transplant was because there was evidence of extra particle disease, disease outside the liver. Many patients were potential candidates, but developed progression during the follow up treatment. Because we follow the patients from distance, we look at the imaging device, which sometimes we have to do biopsies to prove either a positive lymph node or lung metastases. Few, probably a handful of the patients who were sent to us for transplantation turned to be resectable. And I was, Wow, really, this is resectable. So we talked to the patient said, you know you’re resectable. You want to come to register? I can do the resection, but probably I can call one of the surgeons close to you, and maybe will be easier for you to go there. If they want to come with us, they’re welcome to come and we do the resection here. But it has happened that sometimes we find that they are resectable. If you went for third or fourth opinions, which is completely okay, because the most important thing is the patient needs to feel confident that where that patient is going is going to be the right place. I think we have all the opportunities to go and say, Okay, we I can. I want to go and see four or five centers, or four or five surgeons, and then I will decide. But when you decide stick to that, that that would be the best thing, because that creates a much better management that’s my advice. This is the data of our 10 patients. This is not the paper that we published, because remember, the paper was Toronto, Cleveland and Rochester, here is only Rochester, and this is what we’re finding out. The shorter recurrence, around 70% survival at three years. So this is pretty impressive, that it was going to change most likely because our there’s new patient that has a very short follow up, only one of our patients, of our out of the tent, has died after having some recurrence. All our nine patients, the rest of the nine patients are alive. Another patient had recurrence, unfortunately, and is getting treatment with chemotherapy. Now here, this is what we’re doing. We have a trial that we’re going through that known as the patients. Doesn’t have to go through the through, through the trial, but we registry these things here because it may cause a more creates more credibility when when you publish things for this, what we found, this is what we’re working this is my research fellow, Mariana Chavez, where these are 14 cases, 10 cases from Rochester and four cases from Cleveland. I’m not showing which one is which one. And this is so interesting. These are each patient, each patient. This is a cartoon of the when they were diagnosed. The number of metastases in the first column. In the second column is the number of tumors prior to liver transplantation. This is after the patient receive a lot of treatments, RFA, so ablation, y 90, Paddy car three, in fusion, chemotherapy, surgeries, etc, etc, right? And then this is what we found when we remove the liver in pathology. And what is impressive is that 60% of these patients, 60% in in where the pets can set. There’s no cancer here. There was cancer. So the disappearing liver metastases that I’m mentioning, they were still there. I think this is the first time, because this is the first time in the history that we have the entire specimen of the liver out. Normally, when we do live resection, we live, you know, part of the liver for the patient to survive. But this is the first time that we remove entire and we can analyze entire liver, and this is what is happening. We’re finding, clearly, with all the evidence that there was still cancer, there are 60% of time even that it’s disappear. It does not

Speaker 1 50:02
some tips and tricks that we have learned. And this is when I go to give a talk. I think I spend a lot of time with the surgeons talking about this, because they want to learn more about this, the timing from colon resection, because a lot of the patients come okay, I still have the primary side. Can I go for a transplant? Well, yes, you can go for transplant, but we have to remove the primary at some moment, or the patient goes, Hey, my colon cancer is gone. They cannot see it. What is the evidence if we go and do a liver transplant and we don’t touch the colon? I haven’t done that, but I wouldn’t, I. Am sure if we give immuno suppression, there might be some cancer cells in the colon, you will come back. So we have pushed for removing it. There’s one patient that I know that we could transplant that we remove a portion of the column for it was tattoo the cancer, and there was no cancer. But there were other two that apparently disappeared, and when we removed the portion of colon, there was still cancer, so it’s better to remove it, and we don’t want to do experimentation here in large lymph nodes. That’s a big question. What should we do? So we use endoscopic ultrasound, sometimes through the stomach, to be able to biopsy the lymph node to be sure if that’s a positively if not. If it’s a positive lymph node, it’s not a good prognosis. And we use Final aspiration, or sometimes the interventional radiologists use percutaneous biopsy. Or few times we do a laparotomy. We have to Okay. If everything looks good, but we have high suspicious we open the abdomen of the patient before or the day of the patient is coming from outside, let’s say if the patient is coming from far away from, I don’t know, Kansas City and the patient and the donor here, but we have suspicion of that. We start the operation with a recipient. Normally, we start with the donor. Normally, that’s when there’s a donor, a living donor. We start with the donor, and then we bring the recipient to the operating room. But in these situations, we don’t want to put the risk of the donor if we are not sure if we can transplant the patient, so we start with the recipient. We open, we take a biopsy of the lymph nodes there. If it’s negative, then we do, we do the transplant. If not, we have to stop the transplant. Long nodules. We have to review the two more board these what they are very dedicated, and that I’m proud of my team, that they review every single thing, and our coordinators take notes about this so and this is on top of their normal work with all the cirrhotic patients, because I’ve been able to have, in my case, a lot of resources from the department of surgery and the institution to be able to set up a team dedicated for this. But a lot of the other coordinators who are not fully involved with these, are very supportive of all of these. We talk about immuno suppression. We try to bring it down as soon as possible. We have learned more about immuno suppression because we have been trying to change some patients that probably they don’t tolerate it very well when we try to switch them. And we’re learning a lot of those things. And this, I think, a new area that I call it HEPA oncology. We have hepatologies. We follow that follows liver transplant patients, and we have oncologists that follow the patients with cancer. This is putting both things together. Our hepatologist with oncology, and I personally call it our hepato oncologist, and this is what we’re trying to develop here. I think, what time is it? Okay? I’m Hurry up. Betsy. I’m sorry for the same criteria for recipients with the Paducah pump. Just 111, more. Note about the Patriot pump. We have the same criteria for as you can see, the patient is a candidate for transplant after the pump. However, it’s very clear to tell the patient there’s a way higher risk in the transplant. Why the pad three pump creates, unfortunately, damage in the paddy Carter. You cannot use it for transplant. And without the paddy car three, deliver one work. So we need to bring the artery of the spleen, or put a conduit from the aorta from a cabaret daughter. We call it graft or conduit, the portal vein, a lot of the times, is very inflamed because of the pump, and also because of the chemotherapy of the pump in that area, and, you know, a lot of the patients capillary damage. So the risk of transplantation is way higher. We do it, but it’s way higher. The only thing that I see for me is, I think there’s a place for the palm a place for transplant. I don’t think it’s a five more, but what I would say more is, if a patient is responding to systemic chemotherapy, why changing the game? If the patient could be a transparent candidate, continue for one year, complete the year, and probably the patient will be a transplant candidate, if the patient is progressing on systemic chemotherapy, okay, the patient is not going. To be a transplant candidate. Let’s give the pump, right? And if it comes back to conversion and respondents, they doing well and well, then find surgeons who want to play hard ball and do this transplant. But if not, I wouldn’t change them the positions here, I think I will stop here. These are the areas where I think the patients are probably four areas that I call it transplant, transplant categories, those patients who we see these since the beginning were unresectable, and they still have the primary inside you, patients who have multiple metastases, but they have multiple treatments, surgeries, ablation, pump, etc, etc. And I call it more burnout, cancer burnout, liver patients who are unresectable because they have recurrence, and probably this is an area where it’s going to be extending those ones who were unresectable and converted to resectable. Perhaps transplantation will benefit this patient. And to finalize, I told you about this patient, right? Look at these metastases, this patient, and then this patient responded. And some surgeons say I can resect that, the patient decided, and we did a liver transplant because we were sure there were more metastasis. Sorry to show you this, but this is the liver. And look at the metastasis. This is the left side of the liver. Should, sorry to show you these, but 12345, here. This is the left side which I’m showing it here. 123, and this is proven that there’s cancer here. So we would do a right hepatectomy for that patient that here, they said, Let’s do a right hepatectomy only to remove this part. We will be removing this part. We will live in all these cancer. So I think we did the correct thing. This is another patient. Look at this amount of disease. Of course, this is unresectable, and this is the amazing the same patient, I promise you. It’s impressive. The response that the patient had. Look at this amazing patient came here for transplantation. This is their lovely donor. We remove the right side of the liver, a beautiful left side of a liver, enough for the donor. And this is the right side of a liver where we use it for reconstructing it. And you can see here, once the blood came into the new liver of the of the recipient, and it looks pink and beautiful. I know probably you don’t feel that this is beautiful, but it is, and this is what we find in the explant. The pathologist look at these spots of cancer. It’s suppose that here it almost disappeared minimal disease. But when we go and see in the pathology multiple spots of cancer, they’re still there. That’s what I want to show you. Another case. Look at lost those liver metastases. Patient responded so well, you can see these calcifications. And, you know, I, I’m part of these. So if, if you would bring me this patient when I was in Canada, when I didn’t have an idea that we were I was going to be doing liver transplantation, I will take this patient to the operating room and try to do resection or Alps, or two stage protections or something. We did a liver transplant, and there were multiple metastases still in the liver, as you can see here, 234567, here in the back of the liver, we’re taking a lot of this tissue as well, with the consent of our patients, that we consent them into my lab, and because we’re trying to analyze more of the biopsies to understand more about the immune system that is playing a role in this cancer, to hopefully, in the future, being able to find markers and decide which patients are going to respond better. And in conclusions, surgery is the goal in metastatic colorectal cancer and surgery, I include transplantation. There are favorable results with chemotherapy, and we have gone far away, and that’s what is helping us for being able to do liver resections more aggressively. Patients should have the opinion of different treatments modalities to explore second and third opinions. I think the field of liver transplantation is evolving quickly, and we need to be cautious about this. I don’t I hope not a lot of surgeons taking us the new thing, the new toy, and not selecting the patients correctly, the multidisciplinary team, the experience, is very important, and we should keep fighting and moving forward. These are frequently asked questions, but probably the people I would like really that people ask questions and feel comfortable to open your your camera, your screen, ask questions. There are no dumb questions. There are important questions, and I’m here for you, and thank you for this invitation. Again. You.

In this DocTalk, the four lead investigators of the HAI PUMP Trial (EA2222) —  Dr. Andrea Cercek (MSK), Dr. Michael D’Angelica (MSK), Dr. Michael Lidsky (Duke), and Dr. Shishir Maithel (Emory) — joined us to introduce the soon-to-open trial for the HAI Pump for unresectable CRC liver metasteses, review the trial design, inclusion criteria, and answer questions. Recorded in August, 2023.

Betsy Post 00:01
Welcome, everyone. Thank you so much for joining us this evening for our latest DocTalk. I’m so pleased tonight to be with us here for our COLONTOWN DocTalk. Dr. Louise Connell from Memorial Sloan Kettering Cancer Center. Dr. Connell, I think is very well known in COLONTOWN. So if you’ve been around for a while, you definitely know her name. If you are familiar with liver Mets, and especially if you’re interested in the hepatic pump, I know that you definitely have seen her name. And our groups such as Liver Lovers Lane and HAI Pump People, I’m sure that we have some of her patients here tonight to support her as well. So we are so thankful for your time, Dr. Connell, especially for doing this after hours so that we could get maximum participation from our patients and our caregivers. So thank you, again, for agreeing to do this, we’re really excited to hear from you on how you treat patients specifically with the pump. I know that you have some things about the future about the pump, which is really exciting. I’m very excited to hear that. And then we did have patients and caregivers submit questions in advance. So we will get to those questions at the end of Dr. Connell’s presentation. So at the end of her talk, she will, we’re going to do some Q&A based on some questions that we received in advance. As she is presenting, we would ask that you please stay muted so that we can make sure we’re being respectful of her presentation her time, but do put your questions in the chat. So please do use the chat feature to submit your questions. And we will get to those live questions at the end of the presentation and the pre-submitted Q&A. So with that again, Dr. Connell, thank you so much for being here. The floor is yours.

Dr. Connell 01:55
Okay, thank you, Betsy. And first of all, I just want to say thank you very much for the invitation to speak here tonight to you all. COLONTOWN is is a resource that I hear so much about from my patients, and a platform that I think provides so many of you with information that you bring to the clinic, to advocate for yourselves and to, you know, advance your care. And I think, you know, it’s been such an important resource that, you know, if there’s any way that I can help provide additional information, particularly about the liver pump. This is an honor to be asked to do this. So tonight, my slides section is small on purpose, because I really wanted to give you all an opportunity to ask questions. And I would encourage you to submit any questions that you have for me. I did just want to provide some background on you know where we are today, today in terms of metastatic colorectal cancer treatments, and in particular, the role for HAI therapy. I think many of you already know much of this information. But in particular, for patients and caregivers who perhaps are new to this or maybe considering a pump, I did want to provide just some background slides on the pump treatment.

Dr. Connell 03:15
I’m going to just advance my slides here. So first of all, I just wanted to put up this disclaimer to acknowledge some of my consulting work. But truly the presentation today is purely for informational and educational purposes. And it’s really based on my clinical experience with patients and my knowledge in terms of pump management.

Dr. Connell 04:16
And at diagnosis, we see approximately 20% up to a third of patients will have liver Mets at diagnosis whereas the majority of patients will go on to develop liver metastatic disease during their follow-up. The question is what are our treatment options nowadays for metastatic colorectal cancer and, I’ll just briefly run through this on this slide on the next slide. But essentially we have or our cornerstone standard of care chemotherapy treatments, and we combine these drugs with biologics. I think increasingly we’re hearing about biomarker-driven approaches and I’ve highlighted here are the four key targets that we look for in patients who are newly diagnosed being microsatellite status. Their RAS status, BRAF status and HER2 status. 

Dr. Connell 05:00
And, of course, you know what I think I’ve always in patients because of the work that I do is the role for local regional approaches and particularly in patients who have liver only disease or liver dominant disease and looking to intermix this and combine it with my chemotherapy drugs and with biomarker-driven approaches to get the best outcomes for patients. So in terms of patients with liver dominant or liver only disease, you know, I consider resection, ablation, of course, hai therapy and also y 90 as well as I should mention radiation treatments to the liver. And also, I think local regional approaches have a role to play in patients who have lung metastases or illegal metastatic disease which is out where you may have an isolated tumor or a small tumor. And you know, maybe you can be more localized with your treatment approach and for the lung that would include ablation resection and also stereotactic radiation. D=So the progress that has been made in the last you know, 50 years is phenomenal. Unfortunately, a long time ago, when patients were diagnosed with metastatic colorectal cancer, and there were no drug options, the recommendation was for best supportive care and, then over time, really, it was single agent 5FU. And this slide shows where we are today in terms of drug treatments. On the left hand column, you really see our cornerstone drugs, which is the Fluorouracil, Capecetibine have been being the oral version Irinotecan and oxaliplatin, and this is what we all know, as, you know, fall Folfox, Folfirir, the combinations of these drugs, looking at VEGF inhibitors such as Bevacizumab, EGFR inhibitor, centuximab, or, or panitumumab in patients who are RAS Wildtype and then on the right column, we see the newer drugs that are out there, right. 

Dr. Connell 07:01
So with patients who have BRAF mutated colorectal cancer, the combination of NRAS and Centuximab, HER2 is now you know, very to the fore in terms of drug therapy, which a centuximab and trust panitunamab. And then there’s been a lot of focus recently in terms of MSI, high disease and Immunotherapy options. And what I always say to my patients in clinic is that this is very important to determine for patients, but it’s such a small group of patients that we see.

Dr. Connell 07:21
And then the third line drugs you know what I would say briefly about these drugs Regorafenib Taz 102, which I typically combined with Bevacizumab, or for Fruzaqla is that these are drugs that, you know, have limited clinical benefit, and they have a high side effect profile. And I’m very selective in terms of which patients I decide to use these drugs for. More commonly, I would personally use TAZ102 with Bevacizumab and but that differs from patient to patient. And what I’ve highlighted on the far right is what I consider the star of the show which is liver directed treatment. And I think it’s so important to think about it in our patients and the core drug that we have is fluoxetine, and then we use Mitomycin you know, further and, you know, down the line for patients or if they’ve, you know, beginning to develop progression on fluoxetine, and I can talk about that a little bit more in the question and answer section.

Dr. Connell 08:52
So what is a Hepatic artery infusion treatment so traditional chemotherapy is delivered through through a vein. You know, in colorectal cancer, we typically have a meta port in place because of the fight through fluorouracil being given in an infusional form. The drug travels through the body’s bloodstream to reach the liver, and only a small portion of the drug will ultimately reach tumors in the liver. And as many of us who are patients and on treatment know, and it comes with side effects and typically, you know, issues such as diarrhea, mouth sores, you know, low blood counts such as neutropenia has. The benefit of hepatic artery infusion therapy is that it’s delivered through a pump first of all, which is implanted just below the skin in the abdomen. The drug is administered through the hepatic artery, directly to tumors in the liver, and it delivers up to 400 times a higher drug concentration to tumors in the liver. So we’re really getting to directly to the problem. And this is just a graphic showing. You know how that works with the pump.

Dr. Connell 10:13
Basically that the liver is a unique organ in that it has a dual blood supply. And we manipulate this information through the use of hepatic artery and fusion treatment. So there’s essentially two vessels which supply the liver, the hepatic artery and the portal vein. And liver metastases are perfused by the Patek artery, whereas what we call normal parenchyma, or normal liver tissue is perfused, primarily by the portal vein. So with hai therapy, we’re delivering the fluorouracil, which is a prodrug of 5FU or so into the hepatic artery, and we get very high concentration of the drug to the liver. And as I mentioned in the previous slide, it’s almost 400 times higher than those achieved by intravenous administration. And, and the important thing here is that essentially, the drug is entirely soaked up by the liver around 97% of the drug, it has a very short half life. So there’s minimal systemic exposure for patients and toxicity from the drug.

Dr. Connell 11:42
So I have two very brief slides just looking at some of the clinical evidence. And on this slide, we see the clinical evidence for HAI therapy in patients who have unresectable colorectal liver metastases. So the first study highlighted here was published in 2017. And basically, this was a case control study, which looked at the use of HAI with modern systemic chemotherapy combinations compared to systemic chemotherapy alone. And you can see even from the bar charts, there’s a there’s a difference there that’s quite visible between the purple bar, which is essentially the combination treatment and the orange colored, which is systemic treatment alone. And what was seen in this case control study is that median overall survival was doubled in patients, when they received combination treatment at around 32.8 months compared to our modern systemic chemotherapy options, which was 15.3 months. And this was even when conversion to resection was not achieved in patients. And this was statistically significant.

Dr. Connell 12:43
On the on the right side, then we see another paper and this was published in 2018. And this looked at like long term results from a prospective trial, and which again, looked at the response to hai therapy, and with systemic treatment, and basically, the overall tumor response rate to the combination of HAI with systemic chemotherapy was 73%. And there was a very high response rates in patients who were chemo naive. So when it was given in the first line, it was 86%, whereas in patients who were previously treated, it’s still very high, it’s 67%. And what we saw here is that 52% of patients were converted to resection with the combination treatment, despite the fact that the majority of these patients had what we would consider a high disease burden within the liver, and many of them had had previous chemotherapy.

Dr. Connell 15:19
I just briefly put up here, and this is really to January questions, you know, what’s the future for HAI therapy? Or how can we further advance what we know? And I think there’s two very important points to bring up here. And I know, these are questions that come up for me in the clinic is, you know, can we combine hai therapy with other systemic treatment options? One that’s very topical, you know, is kind of get it with Immunotherapy. And another would be, you know, some of these other newer drugs that are out there, you know, in particular for a patient to perhaps is her2 positive, BRAF mutated patients. So, you know, can we give them and right now, the honest answer is we don’t have the safety data to combine these drugs together. But it’s something that we do need to consider going forward in terms of trials. And, and also, I would like to highlight the HAI Consortium, and I think that’s a very important group. And it’s essentially a group of centers within the United States and also outside the United States, where we’ve come together, and we’re trying to generate trials. And there is a trial, which has been activated, which I know has been previously discussed here. And I think this is going to be a group that’s going to help propel forward future trials on hai therapy and and help all of you as well as patients in the future going forward. And it’s a very important collaboration to be able to replicate. I think what we’ve seen achieved at Memorial Sloan Kettering in particular with HAI treatment, and can we, you know, replicate that throughout the United States and more globally for patients.

Dr. Connell 17:01
So, what does it mean for a patient then to live with the palms, so just to get to some practicalities, so it does require a surgery to place the pump. And that’s important to say to patients and the majority of patients it’s placed at the time of an open surgery. In some patients where, for example, the colon primary, or the rectal primary has already been removed, and there is going to be no liver resection. There are some newer techniques such as robotic, placement and minimally invasive which are done by some of our surgeons. In terms of recovery. The honest answer is you can you can travel. And you can also continue to do most of the activities that you’ve enjoyed doing before. And during active treatment, the pump has refills every two weeks, you do not get drug every time it alternates between fluoxetine with heparin saline. And it is important to be mindful of the travel schedule. And I do say that to my own patients, because there is a residual within the pump, but you do not want the pump to run dry. So it’s very important to you know, mention any travel to your your treating physician and to try to accommodate that for patients as well. And otherwise, what I also want to highlight, and I mentioned this a little bit with the consortium, but there’s been a huge increase in terms of the number of centers since 2019, that are able to put in a level upon number one, and also for local refill centers. And this is something that is continuing to gain momentum. I think this is something that I learned, I’ll be honest with you during the COVID pandemic was so important for patients because there was huge difficulty in in people being able to commit to coming here every two weeks to New York at for pump refills and, and there’s a lot more physicians out there, and who who can now help assist with local refills. And that can be huge for patients, even if they’re not able to get the flux your dean locally, for example. But coming to coming to New York once a month is much better than having to commit to traveling every two weeks for example. And, and you know, it is important to also to mention that and we are trying to help train local oncologists also who maybe don’t have experience with the pump, but to be able to help some of some of you and some new patients who really want to commit to this to have refills locally. And then just to briefly mention, you know, some of the safety elements with fluoxetine. So, the anterior pump is indicated for the use of fluoxetine and it is contraindicated to the use of this and patients who have extensive extrahepatic disease or if you have limited liver function. And then always important to mention, you know some of the adverse events that can occur with the pump which are rare but serious and we can discuss them a little bit further in the q&a section.

Dr. Connell 19:59
So with that, I’m going to hand it over to Betsy, and we’ll go through the questions. So I’ll stop sharing here.

Betsy Post 20:08
Great, thank you so much. And then please, as we go along, if you do have questions, actually, I have one, two for the end, please do put those in the chat and we will get to those shortly. So the first question we have Dr. Connell is Why is HAI therapy generally done at the same time as systemic chemotherapy?

Dr. Connell 20:31
Yeah, so, you know, this question comes up a lot. And I think the important thing here is the there is a synergy between fluoxetine through the pump and giving it with systemic treatment in particular arena Tekin, and our EGFR inhibitors, but also importantly, we have to protect against the risk of extra hepatic disease, right. So if I have a patient and they’re on track to try to get to a liver resection, what is absolutely devastating for a patient is to get to a surgery. And the procedure is aborted because extra hepatic diseases detected and or for something to develop on a scan prior to surgery. So it’s really to help protect outside the liver, to allow us to focus on the treatment of the liver metastases with the flexibility and treatment.

Betsy Post 21:23
Thank you. How do you determine which systemic regimen that you’re going to use with the metastatic colorectal cancer liver met patients? And how does having a pump alter that?

Dr. Connell 21:35
Yeah, and so the first thing to say is that, while we typically and in the majority of patients give systemic chemotherapy with the HAI therapy, the dosing is automatically lower than it would be if a patient was receiving systemic chemotherapy alone. Because we have to balance the toxicities from using the two in combination. And so there is a different standard dosing of this systemic FOLFOX, for example, as opposed to somebody who’s on FOLFOX own in terms of what to use for patients. So there’s a few things to look at. I think the first thing is, in a patient who is previously untreated, the standard would be to use Folfox.

Dr. Connell 22:19
With the liver pump, and in somebody who possibly comes and they’ve had both treatments, what I take into consideration is I look and see, you know, what response, did the patient get to each individual systemic treatments previously, right? Did their cancer previously progress on Folfox? Do they maybe have stable disease on full theory, but they didn’t get enough of a response, and also the side effects that patients have had from previous treatment. So if somebody comes into me in clinic, and they have very severe neuropathy from previous oxaliplatin, I’m not going to jump to using that drug. So I think what’s important to consider is how the patient’s cancer has responded to previous drugs before the time interval that they’ve had from a particular regimen to perhaps another recurrence or something else developing and also the side effects for the patients from previous treatment.

Betsy Post 23:13
Thank you. The next question is, are there any situations where the HAI therapy might be done without systemic chemotherapy at the same time,

Dr. Connell 23:27
Um, very, very rarely, I have one patient since I began practicing here that I’ve done it in so I very, very select patients. In general, the preference is to give with systemic chemotherapy. Again, you know, in, in the scenario where I decided not to do it, it was a very detailed discussion with the patient about why we were not doing it and the risks of of not doing it together. But in general, it’s given. It’s given with some form of systemic chemo. And, you know, what I prefer for my patients is at least we give a single agent even if a doublet such as you know, 5FU with oxaliplatin or 5FU with Ironotecan is too much. And but as I said, it’s very rare that I do it. I’ve only done it once since I’ve been practicing here and had very real reasons for not doing systemic side effects may be possible in the liver area during HAI therapy.

Dr. Connell 24:28
Yeah, so the side effect profile is very different to systemic chemo. The two main things that I say to patients is we learned early on and many of the studies that were done with the liver pump the the risk of ulceration in the gut in the GI tract, so all patients are put on a medication to help prevent reflux. So pantoprazole protonix, and in patients who say to me that they’re having increasing reflux symptoms, for example, or they’re having some pain or discomfort, you know, just under the chest, and I’d have a very low threat To get an endoscopy to look for an ulcer, so that’s the first thing. But it’s much less common nowadays because we’re routinely giving protonix with it. I think what the big thing is, you’ve got to watch the delivery of blood work very closely. And in the majority of patients, you don’t come to clinic with any symptoms, right? You feel fine, you feel well, in general, patients feel better than they felt on previous systemic chemotherapy because okay, I’m still giving it but I’m giving a little bit less than you would have had previously. And what I always say to people, actually, when they come to me is it can be a little bit frustrating, right? If you fly to me from San Francisco, or you come from Canada, and you feel great, and then I see the liver enzymes, and I say, sorry, I can’t give the drug today or you know, we’ve had to give a few weeks holding off on the drugs. So the honest answer is we’ve learned from experience that we do have to be very mindful of the liver bloodwork, and then the majority of patients picked up on the bloodwork and the patient doesn’t have any symptoms themselves. However, in some patients, if you begin to develop any symptoms, such as jaundice, you know, anything like that, then a very low threshold to get your liver enzymes checked. And even if you’re local, to check them to see because that’s the biggest thing that we have to watch for is liver toxicity.

Betsy Post 26:16
How long does active treatment last? And what is the average number of treatments? And does this change? Does this change if the HAI therapy is being done before or after liver resection?

Dr. Connell 26:30
Yeah, yes. So the answer to the final question is yes. So if somebody has had a liver resection, and we’re using this as an adjuvant treatment, it’s six months of treatment. And then we stop. And in the majority of patients, we’ll get four doses in of the fluoxetine of the liver drug in the six month period, when we look at, you know, liver enzyme alterations, but we stop automatically at six months, and however many doses the patient has managed to successfully get that’s it. And in a in a person who is not resected, or I’m trying to convert to resections, when unresectable disease or in the conversion setting, there really isn’t a limit in terms of the number of doses that a patient can get. And the it really depends on how their liver is tolerating the drug, you know, what kind of response that we’re getting, you will have to make a change to the to the drug dosing. And what I’ve seen in practice is that typically, that happens around two to three months into treatment. It’s not uncommon, that it could happen even after the first dose, but there will be some dose modification. And patients can still respond on low doses. And that’s also important to say, because again, I also acknowledge that, you know, really, you’re committing to come in here for these treatments or to hai center. And it’s very disappointing, if you hear you’re getting a quite a significant dose reduction. And but you still respond to this. And it’s different to what we know about the dose reductions that are done with systemic chemo.

Betsy Post 28:04
Thank you. Is it possible to do treatment again, with the pump later on, if needed? 

Dr. Connell 28:14
Yes, exactly. Yes, you can. And this is why, you know, our, our preference is for patients to keep the pump, right, because particularly, what I would say to patients is, if you are using it as adjuvant therapy after liver resection, or you’ve been converted to resection from the pump, at the time of surgery, the recommendation, so your NED at that point, right is at least two years. Ideally, we prefer patients to keep the pump in longer. But the highest risk period for recurrence is the first two years and the rationale behind that is because the pump is not something that can be put back in right a little bit like a metal porch, right? So we want to keep that option open. Particularly if, if it’s helped you get to your surgery, number one, and you know, so that we can use it again. So absolutely, yes, you can use the drug again.

Betsy Post 29:11
Thank you already answered the next one, which was does the pump stay in when active treatment is done? And for how long?

Dr. Connell 29:18
Yes. Yeah. Yeah. And so yeah, and this question comes up and the honest answer is as well what I would say is i i Never tell someone to take a pump out I wait for them to tell me that they’re ready for it to come out because I think it’s a very personal decision. I think it’s something that for many patients has been you know, revolutionary, I guess and and I think, you know, we can educate and guys and that but it has to feel right to you as a patient to know when is the right time to remove it. If somebody really wants it out within six months. I’m like, please keep it for two years but beyond that, I really leave it up to the patient’s decide

Betsy Post 29:59
Are there other drugs ever used in the pump like oxaliplatin?

Dr. Connell 30:05
Yeah, so, oxaliplatin has a very low extraction rate into the liver. It is used in Europe because they have a slightly different device there. We don’t routinely use it here. But we do use Mitomycin and that’s something I referred to briefly during my talk. And I have seen patients who perhaps are beginning to develop some resistance to Flox your deen or maybe are beginning to run into more issues with their liver enzymes. And I’ve used Mitomycin in those patients and seen you know, some very good responses with the middle myosin what I would just say about that is you can give it in combination with fluoxetine. So you can give both drugs at the same time if your liver enzymes are good. So if the liver bloodwork is good, if the liver enzymes are high, tickling the outsource or perhaps the bilirubin, and that it’s safer to give Mitomycin on its own, but that’s typically our second drug that we use. We don’t give oxaliplatin.

Betsy Post 31:09
What are the causes for the mitomycin following HAI therapy with the traditional treatment?

Dr. Connell 31:19
Why would we give it right?

Betsy Post 31:21
I think you already spoke to that. 

Dr. Connell 31:24
So yeah, yeah. So I think if you’re getting a slowing down in response, possibly to flux, your routine, maybe you are getting some response, but you’re beginning to run into some of these liver toxicity issues. And so they would really be the main reasons that we do it. And really, I would use it in a situation where it’s liver only progression, of course, like I wouldn’t use it if there was signs of anything happening

Betsy Post 31:47
Um, and then since I’m not an oncologist, I might mess up these names. But what are the views on the use of Bev, which I know is Avastin. So we’ll take that one first. The new third line or a drug that was just FDA approved for colorectal cancer, liver Mets, or the EGFR inhibitors. So what are the views on those three and maybe address them separately? Because I know it could be different after the HAI therapy when the pump is running glycerin.

Dr. Connell 32:18
Okay, so I’ll start with EGFR inhibitors first, because that’s probably the easiest ones you can give EGFR inhibitor is at the same time that you give fluorouracil safe to do works very well with the liver pump.

Dr. Connell 32:32
And you can also give it after liver treatments. So there’s no limitation at all with EGFR inhibitors and actually works very well with with FUDR, or Avastin is something that we’d urge early on, that should not be used the same time that we’re giving fluoxetine. So it’s it’s a combination, so it should not they should not be used together. And but a patient can have Avastin or Bevacizumab later on, if you’re simply just getting glycerol through your pump. And so, if for example, I have somebody who the liver is still no evidence of disease, there’s, you know, issues arising outside the liver in the lung, perhaps or lymphnodes. Have I given Avastin? Absolutely I have, I generally prefer to try to delay the use of Avastin further out from using the liver drug because I have seen in some patients some delayed issues with billary complications if I’ve tried to use the Bevacizumab a little bit too quickly after stopping the liver pump treatment. And but yes, you can use them separately but not together and then forget never the honest answer is we don’t know yet. Because it’s such a new drug definitely would not use them together. And I think you know, you would think along the same lines as you know, what we do with Stivarga, etc. You know, they can be given but not together. And the honest answer is and I kind of led to this during my sliders, I really reserved the use of any of these drugs too much, much later on for patients. I think if you can do something like long ablations or radiate, I think you’re helping the patient more than jumping to any of these newer, third fourth line drugs that are approved.

Betsy Post 34:17
Thank you. And these are questions that we see in Colin town all the time, and these were the most frequent questions that I received for you. So these have to do with Y90 So if a patient has had Y90 How does this affect their ability to receive HAI therapy after?

Dr. Connell 34:38
Yeah, okay. So this comes up quite a lot. The honest answer is if I see a patient before a Y90 Maybe they come with a second opinion we usually prefer to give the pump before Y90 that’s the honest answer. So usually what I say to patients is, you know, pump first and any of these proceed procedures like Y90 or radiation I would reserve for later on. And have I had patients who’ve had y90 And I’ve given pump treatment to absolutely, I think we have to look at those cases individually. And it’s something that we would show at our tumor board. And we would really look at the extent of the Y90, for example, how the blood vessels in the liver look after the Y90.

Dr. Connell 35:24
Often you need to dose reduce the flux your routine a little bit faster in those patients so I can get the drug in for the patient, but I can’t get as much drug in. And but I’ve had people respond after y 90 I think our preference is to do pump first.

Betsy Post 35:45
If a patient has HAI therapy, and then does Y90? Would the patient be able to use the HAI pump again, if it is still functional?

Dr. Connell 35:56
Yeah, and so this is an interesting one. I haven’t personally ever done that myself. I think from a technical point of view, it would come back to what I said previously, is that you’d have to really look structurally at the liver and see, you know, there’s there’s newer Y-90 techniques out there. And I know whether our interventional radiologists here they do more selective Y90 So if perhaps, you know, there was a regional Y90 And then you’re trying to treat the rest of the liver. Technically, you could. I think just with with my own practice, and the way that I view it, because I keep Y90 for Later on, it just hasn’t worked out that way with the patients that I’ve seen. But again, I think this is something that you would have to have the right imaging, it would have to be viewed as a multidisciplinary team, whether that’s the right thing for the patient, you know, including an interventional radiologist, including a radiation oncologist right, is radiation safer than Y90 A surgeon and a medical oncologist to decide what’s the right thing for that particular person.

Betsy Post 36:56
Some additional questions have to do with transplants. This is something that we’re hearing more and more about, especially for unresectable disease, obviously, and we have patients a lot of times that are making a decision, sometimes between the pump or transplant, but something that we’re hearing now is the question first, could the pump be used as a bridge to liver transplant?

Dr. Connell 37:18
Yeah, so this is very typical? I think without intentionally setting out that way. And I’ve had some patients who’ve done very well with transplantation after pump treatment, I think the tricky thing about the transplant process is that it’s a long process for patients. Right. So my own experience with my patients has been is that sometimes they’re waiting like 12 to 18 months. And I’m trying to control everything with the pump at the same time. So I have used it but not intentionally. I’m on discussions with transplant centers. And speaking with surgeons here, this is something that I think we’re going to need to study. And we’re going to need to collaborate on to see if we can help more patients by combining the two techniques.

Betsy Post 38:37
Another question, how do you consider the option for liver transplant as part of your overall treatment plan or approach for patients?

Dr. Connell 38:47
Yeah, so. So when I see patients, you know, this can often come up. And I think with transplant, what I say to people is we got a real sense of how the pump is helping a patient in unresectable disease, like, you know, about six months in, you know, look, and you’re talking back and forth with the surgeons, you know, do we think that we’re going to be able to convert to resection here? Do we have any of these options like why nine tear or radiation? And I think it’s always appropriate to get an opinion from a transplant center, and particularly if it’s something that the patient themselves is questioning, right, because you want to hear directly. And there’s a little bit of bias right between different different specialties and obviously I’m very Hai and but I’ve certainly collaborated with transplant centers, and then you know, when somebody is listed for transplant in practice, what I do is I follow what they want me to do, so I don’t change any treatment, you know, they tell me what they want to do. The important things about transplant is a few things. So you cannot have any extra hepatic disease obviously so there can be no evidence of extra hepatic disease. And the second thing is that the primary tumor has to be removed.

Dr. Connell 40:03
So, you know, they would be the two things. But if you have liver only disease and and resection is not feasible, and you’ve heard that from the liver surgeon and you’ve heard that from your medical oncologist then then I do think transplant is something that needs to be considered. And they removed the pump at the time of transplant as well. 

Betsy Post 40:26
So is there data available to show how successful ATI therapy is? And I know that we did talk? You talked about that earlier, but I didn’t know if you wanted to elaborate on that a little bit more.

Dr. Connell 40:39
Yeah, so we do have data. And I’ve shown some of the data here, I think what’s important is that we need more randomized to data. And I think, you know, that’s what the consortium is going to help with and why we’re trying to collaborate with other institutions. And I think trying to address this question of, is the pump so successful? Because it’s given here in New York or you know, Kansas, can I get the same level of care? Or in Chicago, or, you know, Atlanta? And I think the honest answer is there’s so much more knowledge out there about the pump. And we do need to do more trials. And also, I also mentioned this as well, there’s so many newer drugs out there, right. And patients want to know can kind of get them together, is it safe to get them together? And this has to be done in a trial setting.

Betsy Post 41:27
So another question we get quite a bit. So now that Dr. Kemeny has retired, how was care being distributed for patients that are being seen at Memorial Sloan Kettering?

Dr. Connell 41:39
Yeah. And so what I would say about that is, honestly, all of us can can can do pump treatment, I think a huge part of Dr. Kennedy’s legacy. What’s visible to patients and caregivers is is what she did for you, right? Understandably, a huge part of her legacy for us at Memorial is the teaching and training that she gave to us. And, you know, she was a phenomenal mentor to me. And to many of my colleagues.

Dr. Connell 42:10
All of our practices differ a little bit. So some of us do more pump than others. But honestly, all of us can do pump in terms of her practice. And it’s been divided between Athol I think for for active patients, understandably, because I was mentored under her I have many of her patients. I think, what’s also important to say, though, is that, for any of you who have, you know, some complex decision making, there’s something to be to be, you know, figured out, you know, is it now the right time to think about y 90, you know, have I achieved what I can with the pump, that’s never a decision that’s made in isolation by an individual, whether that’s a medical oncologist, it’s our tumor board is a huge resource for people and, and that’s often what I what I see myself as like, You’re not coming here to memorial for me, you’re coming for the expertise from the whole group. And never think that a decision a very important decision like that, look, will I say to this patient that you should go and get a transplant opinion, you’re not going to hear that just for me, I’m going to speak with my surgeons I’m going to speak with with them, and we’re going to show your case at the tumor board. And I think that’s very important to know, is that there’s huge collaboration amongst us as medical oncologists, and also multidisciplinary team involvement in any major decisions for patients.

Betsy Post 43:31
I know that you spoke about the Consortium, and that all the pomp programs, especially since my team that have opened up, but How can patients across the country get good access to HAI therapy?

Dr. Connell 43:44
Yeah, so I think there are more centers, who are implanting the pumps, number one, and also so many more centers where, you know, they’re able to assist with with local fields, I think the consortium is really helping with that. I would also say that there’s a huge collaboration between us, you know, I definitely speak with medical oncologists at other institutions. You know, I relied on mentoring, when I started off with this, and I try to share what I’ve learned in the nuances, you know, with oncologist with other centers, I think, when you start off, you know, what I always say to people is, you have to be comfortable with the person that’s treating you, right. And whether that’s having a pump or not having a pump, I think, number one, you have to be comfortable. So, you know, and you also have to think from a practical point of view, you know, look, if financially and with my family or my work commitments, is it feasible for me to fly up and down to New York every two weeks? And for many patients, it is for others. It’s not. Do I have a local doctor who can do this? Did I did We did our personality match? You know, and but I think there is so much more knowledge out there nowadays and there’s also huge camaraderie between us and sharing of knowledge. And, I think the consortium and the trials and everything that’s going to come out of that is going to further reinforce that for patients.

Betsy Post 45:11
One more question, and then we’re going to take the live questions, we have quite a few. How does the start of that new pump trial impact the ability of new patients to receive HAI therapy?

Dr. Connell 45:23
Yeah, so it’s a very relevant question. And you know, what I would say about the pump trial, it’s a very, very select group of patients, right? It’s a very important study, right to help answer this question, in a randomized setting of, you know, conversion to resection for patients with HAI versus modern systemic chemotherapy. So it’s for patients who’ve had more than three months, but less than six months of systemic chemotherapy in the first line. So it’s a very small group of patients. And the honest answer is the reason that we’re doing that is because we don’t know the question, right, we are the answer, we wouldn’t be doing it if we already knew that one was better than the other. And that’s important to say about any trial. If you’re a patient who is untreated, you had no chemotherapy, you can have a pump off trial, if you’ve had more chemotherapy, like you’ve had a year of chemotherapy, you don’t, you don’t qualify for the trial. So it’s a very, very select group of patients. And that will be explained to you as well, in the in the in the clinic setting.

Betsy Post 46:30
So moving on to some of our live questions, we have one, is there a certain temperature that you have to keep your body under while you have a pump?

Dr. Connell 46:42
Yeah, so this question comes up quite a bit, you know, I think you have to be sensible, right? So he will speed up the rate of infusion of the drug. Hot tubs are a no, no, you can get in a swimming pool. And so body temperature can affect us, I don’t give anyone like a specific number. But I just say like, you have to be mindful of it. And I have a patient who said they have a hot tub with that, put it on regular temperature. So you know, swimming, and all of that is fine. But sitting in heat, you don’t want to put heat pads directly on the pump. If you have pain in your back for another reason, you can put heat out there, but you just want to do want to put it directly over the pump.

Betsy Post 47:25
Is it true that you can’t lift more than 10 pounds when the pump isn’t?

Dr. Connell 47:31
Yeah, so again, this comes up quite a bit. So usually I say around 15 pounds to patients. In the beginning, I think you have to be very mindful of that similar with any surgery to be honest with you. Over time, honestly, what happens is you have a very good sense of your pomp and also scar tissue forms. And so I tell patients that, you know, using a binder, you know, be sensible. But a lot of people say, Well, you know, my toddler is 30 pounds, you know, and I’m never gonna say to somebody, you can’t lift your child up, you know. So I think within reason, and I think if you’re, you know, the further out, you get the sense you have your palm, the binder, scar tissue, and, and, you know, for lifting children in the beginning, I usually say to people, you know, sit down and lift them up onto your knee, you know, things like that. So I try to be creative with how you do things. But I do think we have to be practical in that regard. And the concern about the weight lifting is the connection between the catheter and the pump, and also the risk of, you know, the pump flipping, and the more secure it is over time that the lower the risk of that

Betsy Post 48:39
Um, there’s a question about the drug and mutations. And I know specifically, we do have some BRAF patients here. So question, there’s a question about, is the HAI therapy equally effective for all mutations?

Dr. Connell 48:56
Yeah, so it’s a very good question. I think what I would say to you is, is that we do use the pump and in all patients, I certainly have myself patients who have BRAF mutations, and I’ve used the pump, and I’ve seen some very good results with it. So I wouldn’t discriminate based on that. And but I think it’s something that we’re going to need to study a little bit further to see how we best serve people going forward. But I definitely have patients who’ve done well. And you know, maybe later on I’ve used the combination I mentioned earlier, such as graphics to toxic map, and but if they have liver only disease, we still put pumps and we still get flux your routine and I’ve definitely seen good responses. I have a patient who was probably an outlier but from from early 2019, and still NED

Dr. Connell 49:47
and had, you know, resection, had liver pump to get your resection and as BRAF mutated, you know,

Betsy Post 49:55
right. I think you answered this, but I’ll ask it for those pursuing liver resection, is there a recommended number of fudr treatments from the pump before considering surgery?

Dr. Connell 50:10
And so the honest answer is there isn’t a set number per se, if somebody has unresectable disease. So what we do is we scan every two months because we want to keep a close eye on the response that we’re getting and how the liver is tolerating it, right? So you’re scanned every

Dr. Connell 50:29
which is a little bit different to the adjuvant in the adjuvant setting, you’re scanned every three. But what I usually say to people is that honestly, at two months, it’s it’s not very common that patients are ready for surgery, it’s typically around the four to six month mark, but there isn’t a set number is really depends on the location of tumors, the technicality if somebody has liver, you know, bi lobe disease, so both the right and the left side involves the surgeon will say to me, Look, we need to do these portal vein embolization, you know, certain procedures to help get to a second stage liver surgery. So the some of those factors to come in. But there’s no hard and fast rule with the number of doses that a patient has to have

Betsy Post 51:13
HAI pump decisions require very close coordination between the medical oncologists and surgical oncologist Are there any best practices from that cross specialty communication that you would highlight is beneficial to apply? Even beyond the HEI application?

Dr. Connell 51:31
Yeah, so, you know, what we’ve learned to serve patients best is that multidisciplinary involvement is so so important. Right? And, and I kind of, you know, said that earlier on, like, any major decision point you need to think about, you know, how am I helping the patient right now? And also, how is this going to affect what I want to do in the future for the patient? Right. So in my own practice, here, I do my clinics alongside the surgeons at for that reason. And you know, when I asked some of these questions, we also have very heavy input from our interventional radiologists. And I think that’s very important is to try to get the different options there. And sometimes there is there’s two options, right maybe let’s say for the liver, it could be resection or it could be ablation, and then we can see both and help make the decisions by getting the input from from both specialties for example.

Betsy Post 52:32
Are there restrictions on jogging and working out?

Dr. Connell 52:37
Okay, so what I would say about that is if you put 20 of us in a room, a mix of surgeons and medical oncologists, everybody would say something different and it’s very controversial. And I allow my patients to light jog and the the concern again is really the connection of the catheter to the pump. And again, what I say to people is exactly what I said weightlifting you know, if someone comes in to me and you know jogging is your is your your cam time, you know, your therapy so to speak. You know, it’s very hard to say to somebody, you know, don’t jog and but I say you know, try to be sensible about it, have a binder on Wait a while and I do allow patients to do like jogging. The surgeons do lap people jog and there’s other medical oncologists who say no, and we love stationary bike. We love the peloton. That’s, that’s probably the safest thing that you can do and the best thing and a good form of workout. But yes, I do say to patients, they can jog.

Betsy Post 53:41
So if there is a patient that has, for example, ovarian or peritoneal disease, but the patient was potentially able to have all of that removed. Could they still get pumped?

Dr. Connell 53:56
Um, so for over a yes. So if you have liver and ovary because we know that colorectal metastases to the ovary, are quite resistant to chemotherapy, so in general, the bias is to lean towards surgery in that situation anyway. So you would often do if you can do a liver and you would also remove the ovaries at the same time. So yes, with peritoneal disease, there’s a little bit of pause. I’ll be honest with you. The tricky thing about peritoneal disease is that you often can’t fully appreciate peritoneal disease on scans. And and it’s only at the time of surgery that you really have an understanding. And I’ve had some patients where perhaps there’s been like limited peritoneal disease, you know, a year ago it was removed and maybe they come looking for a pump. And and usually if there’s, you know, a period of time, typically a year, year and a half, not thing happening in the parish name again, then, you know in select cases we’ve put pumps in. And but I wouldn’t say to you upfront that I’ve put a pump in for a patient when they have active peritoneal disease at the same time.

Betsy Post 55:14
For every two to three months scans, do you do CT MRI, and I’m gonna throw in there you PET scan stew? Might as well add it in.

Dr. Connell 55:24
Yeah, and, okay. Um, so in that regard, what I would say to you is I started off using CT and patients. So I do routinely, CT chest, abdomen and pelvis. Over time. From looking at the CT scan, you understand with the individual patient, whether you’re seeing things clearly in the liver or not, if not, particularly in patients who maybe have, you know, a lot of chemotherapy prior to the pump being placed, because the chemotherapy changes the texture of the liver, what we call like fatty liver change, or sclerosis. So in those patients in MRI may give additional information. So the honest answer is, my starting off rule is CT only, I’ll involve an M or liver if I feel like I’m not seeing things clearly with a CT. And I really don’t routinely use a PET scan, unless I get to a point in a patient where a specific question has come up on a on a CT, for example, I do a patch, and I see that the patch is giving more information than the CT has. Similarly, if I do a patch on a patient, and I see that I’m not getting anything different from it, then I don’t routinely follow with Pat. And I think that would be the standard approach. For most patients. The tricky thing with PET scans is there can often be you know, false positive things on a PET scans and something lights up. And it’s it’s not anything related to the cancer and then it causes, you know, a lot of concern, understandably. Yeah, so that’s how I would view it. But I do have some patients where I know that only MRI shows that are only pet shows that and then once I learned that with the patient, then I continue to use that imaging modality. But I still always do my CT as well.

Betsy Post 57:12
We have one more question about I think exercise I see here. What about horseback riding? I’m a serious equestrian.

Dr. Connell 57:21
Yeah, so this came up for me recently. The issue with with horse riding is the bouncing activity. Right and the concern for the catheter? Again, I don’t think it’s a complete contraindication I think, and I know I’m repeating myself a lot but wearing the binder, a similar lead to what I’m seeing with light jogging. I mean, you can I don’t even know the word for isn’t trotting. for horse riding, you know, you have to be mindful of that. And but I wouldn’t, you know, I wouldn’t say you can’t do it again, if that’s something that a patient is passionate about, and it’s their form of relief, or escape from what’s going on, then I think that’s important to consider. So have a binder be mindful. That’s what I would say.

Betsy Post 58:07
We just have two or three more. So how would you know if there’s a problem with the connection from the pump? Perhaps from over lifting, etc?

Dr. Connell 58:19
Yeah, the honest answer with that is that most patients don’t know. And it’s picked up on scans. That’s the most common scenario. And that’s really where we see it. If somebody has, you knows, for example, they’ve had a trauma, you know, so So I had a patient a few years ago, and they were in there on a regular bicycle, and they flipped over the handlebars, and they were like, This doesn’t feel right, you know, so I scanned and you know, there you knew there was some incident proceeding, and you would check for it or they had pain afterwards. But the honest answer is in the majority of patients picked up on scans and you don’t feel any difference.

Betsy Post 59:03
Let’s see, I know I’m gonna mess this this word up.

Dr. Connell 59:08
So what are the thoughts around using the capecitabine with the pump while receiving radiation to treat the primary replacing traditional systemic treatment? Okay, yeah, so this comes up quite a bit. So when patients have a rectal tumor and you know, you can treat them with chemo radiation. So we do, you know, and you know, that’s in terms of a rectal tumor, the surgery is much more life altering. So if you can effectively get a complete clinical response or fully treat the rectal tumor than chemo radiation is recommended. What do I do in my patients? So the issue with Capacetibine Xeloda is that it causes more increase in liver enzymes, and it can affect the dosing of the fudr. So what I do for patients is if

Dr. Connell 1:00:00

We have a rectal primary and we’re doing chemo radiation. And we’ve just put a pump in for liver disease, you can give the fudr you can give the liver treatment during the chemo radiation. But instead of using the Xeloda and or capecitabine of being I use fluorouracil which is sort of the old way that they that they used to do chemo radiation. And because again, I want to try to maintain the higher doses in the pump and keeps it being tends to interfere with that more. So.

Betsy Post 1:00:36
I think I got to almost every question, one of my questions that I have, if I can just sneak one in I know it’s 802. But with all the centers opening up, I feel like we’re seeing some oncologists are using the Urso dial and some are not. And I don’t know if you feel comfortable speaking to that, and how you use it in your practice and how the decisions made to use that or not?

Dr. Connell 1:00:59
Yeah, it’s a very good question. I mean, I think what I would say to you as well is there’s even differences in the practice here at Memorial as well. I, I use it quite early on in patients, because I think, you know, the two ways we manage the liver inflammation are the steroids through the pump at the time of the flush as well as versatile. And, and in the long term for patients being on steroids continuously. You know, there’s this kind of late side effects with that there’s the weight gain that comes from steroids, there’s a few patients where versatile can be a little bit tricky. So sometimes patients can notice the very loose stool. So if I have a patient who’s struggling with, you know, diarrhea issues or anything like that, from arena Tekin, or even five floor yourself, I kind of hold off on the earth a dial, but I tell them why I’m not doing it, you know, but I do tend to use it early on. And I also tend to keep it on board longer, even after I’ve weaned down the steroids in the pump, and I have someone off treatment, because I think it helps with the liver inflammation, I typically start off on twice a day in some patients, you may have to go up to three times a day. But again, if you even select 10 oncologists here at Memorial, everyone would do something a little bit different. But I give the options to patients. And I also explain, as I said, when I don’t use it and what my concerns are for that particular person.

Betsy Post 1:02:31
Well, it’s 8:04. And I think we have gotten to most of the questions. There is one here that I’m not sure we may have to get back to because it’s you know, the top centers for ATI. And with so many new centers that have opened up since 2019. I think by volume, we’d have to kind of look into that to see who they are. I know Duke is one of them. I know they’re very, they’re a high volume center now. But with the opening of the consortium, I know we have a lot more centers throughout the US. So I can take that offline. And definitely I can talk to the folks at inteiro on that as well. Just about the volume at the other centers. But yeah, so I just wanted to say again, thank you so much for your time, I learned a lot. And it was so good to hear just from a medical oncologist. So in addition to Dr. Kemeny and hear how you’re using it, your practice, and I learned a lot of just about the trial and other things. And your take on that. And I really appreciate it. I know you were so generous with your time and answering all of these questions for the patients. And we really all appreciate it. So thank you so much. And I know we’ll be in touch if we have additional questions. So thanks for everybody that attended tonight and thanks for all your participation. We really appreciate it. So have a great evening. Thanks again. And we’ll see you soon.

In this DocTalk, Dr. Nancy Kemeny from Memorial Sloan Kettering discusses HAI pumps for treating liver metastases in colorectal cancer. Recorded in September, 2023.

Betsy Post 00:01
Welcome, everyone. Thank you so much for joining us this evening for our latest DocTalk. I’m so pleased tonight to be with us here for our COLONTOWN DocTalk. Dr. Louise Connell from Memorial Sloan Kettering Cancer Center. Dr. Connell, I think is very well known in COLONTOWN. So if you’ve been around for a while, you definitely know her name. If you are familiar with liver Mets, and especially if you’re interested in the hepatic pump, I know that you definitely have seen her name. And our groups such as Liver Lovers Lane and HAI Pump People, I’m sure that we have some of her patients here tonight to support her as well. So we are so thankful for your time, Dr. Connell, especially for doing this after hours so that we could get maximum participation from our patients and our caregivers. So thank you, again, for agreeing to do this, we’re really excited to hear from you on how you treat patients specifically with the pump. I know that you have some things about the future about the pump, which is really exciting. I’m very excited to hear that. And then we did have patients and caregivers submit questions in advance. So we will get to those questions at the end of Dr. Connell’s presentation. So at the end of her talk, she will, we’re going to do some Q&A based on some questions that we received in advance. As she is presenting, we would ask that you please stay muted so that we can make sure we’re being respectful of her presentation her time, but do put your questions in the chat. So please do use the chat feature to submit your questions. And we will get to those live questions at the end of the presentation and the pre-submitted Q&A. So with that again, Dr. Connell, thank you so much for being here. The floor is yours.

Dr. Connell 01:55
Okay, thank you, Betsy. And first of all, I just want to say thank you very much for the invitation to speak here tonight to you all. COLONTOWN is is a resource that I hear so much about from my patients, and a platform that I think provides so many of you with information that you bring to the clinic, to advocate for yourselves and to, you know, advance your care. And I think, you know, it’s been such an important resource that, you know, if there’s any way that I can help provide additional information, particularly about the liver pump. This is an honor to be asked to do this. So tonight, my slides section is small on purpose, because I really wanted to give you all an opportunity to ask questions. And I would encourage you to submit any questions that you have for me. I did just want to provide some background on you know where we are today, today in terms of metastatic colorectal cancer treatments, and in particular, the role for HAI therapy. I think many of you already know much of this information. But in particular, for patients and caregivers who perhaps are new to this or maybe considering a pump, I did want to provide just some background slides on the pump treatment.

Dr. Connell 03:15
I’m going to just advance my slides here. So first of all, I just wanted to put up this disclaimer to acknowledge some of my consulting work. But truly the presentation today is purely for informational and educational purposes. And it’s really based on my clinical experience with patients and my knowledge in terms of pump management.

Dr. Connell 04:16
And at diagnosis, we see approximately 20% up to a third of patients will have liver Mets at diagnosis whereas the majority of patients will go on to develop liver metastatic disease during their follow-up. The question is what are our treatment options nowadays for metastatic colorectal cancer and, I’ll just briefly run through this on this slide on the next slide. But essentially we have or our cornerstone standard of care chemotherapy treatments, and we combine these drugs with biologics. I think increasingly we’re hearing about biomarker-driven approaches and I’ve highlighted here are the four key targets that we look for in patients who are newly diagnosed being microsatellite status. Their RAS status, BRAF status and HER2 status. 

Dr. Connell 05:00
And, of course, you know what I think I’ve always in patients because of the work that I do is the role for local regional approaches and particularly in patients who have liver only disease or liver dominant disease and looking to intermix this and combine it with my chemotherapy drugs and with biomarker-driven approaches to get the best outcomes for patients. So in terms of patients with liver dominant or liver only disease, you know, I consider resection, ablation, of course, hai therapy and also y 90 as well as I should mention radiation treatments to the liver. And also, I think local regional approaches have a role to play in patients who have lung metastases or illegal metastatic disease which is out where you may have an isolated tumor or a small tumor. And you know, maybe you can be more localized with your treatment approach and for the lung that would include ablation resection and also stereotactic radiation. D=So the progress that has been made in the last you know, 50 years is phenomenal. Unfortunately, a long time ago, when patients were diagnosed with metastatic colorectal cancer, and there were no drug options, the recommendation was for best supportive care and, then over time, really, it was single agent 5FU. And this slide shows where we are today in terms of drug treatments. On the left hand column, you really see our cornerstone drugs, which is the Fluorouracil, Capecetibine have been being the oral version Irinotecan and oxaliplatin, and this is what we all know, as, you know, fall Folfox, Folfirir, the combinations of these drugs, looking at VEGF inhibitors such as Bevacizumab, EGFR inhibitor, centuximab, or, or panitumumab in patients who are RAS Wildtype and then on the right column, we see the newer drugs that are out there, right. 

Dr. Connell 07:01
So with patients who have BRAF mutated colorectal cancer, the combination of NRAS and Centuximab, HER2 is now you know, very to the fore in terms of drug therapy, which a centuximab and trust panitunamab. And then there’s been a lot of focus recently in terms of MSI, high disease and Immunotherapy options. And what I always say to my patients in clinic is that this is very important to determine for patients, but it’s such a small group of patients that we see.

Dr. Connell 07:21
And then the third line drugs you know what I would say briefly about these drugs Regorafenib Taz 102, which I typically combined with Bevacizumab, or for Fruzaqla is that these are drugs that, you know, have limited clinical benefit, and they have a high side effect profile. And I’m very selective in terms of which patients I decide to use these drugs for. More commonly, I would personally use TAZ102 with Bevacizumab and but that differs from patient to patient. And what I’ve highlighted on the far right is what I consider the star of the show which is liver directed treatment. And I think it’s so important to think about it in our patients and the core drug that we have is fluoxetine, and then we use Mitomycin you know, further and, you know, down the line for patients or if they’ve, you know, beginning to develop progression on fluoxetine, and I can talk about that a little bit more in the question and answer section.

Dr. Connell 08:52
So what is a Hepatic artery infusion treatment so traditional chemotherapy is delivered through through a vein. You know, in colorectal cancer, we typically have a meta port in place because of the fight through fluorouracil being given in an infusional form. The drug travels through the body’s bloodstream to reach the liver, and only a small portion of the drug will ultimately reach tumors in the liver. And as many of us who are patients and on treatment know, and it comes with side effects and typically, you know, issues such as diarrhea, mouth sores, you know, low blood counts such as neutropenia has. The benefit of hepatic artery infusion therapy is that it’s delivered through a pump first of all, which is implanted just below the skin in the abdomen. The drug is administered through the hepatic artery, directly to tumors in the liver, and it delivers up to 400 times a higher drug concentration to tumors in the liver. So we’re really getting to directly to the problem. And this is just a graphic showing. You know how that works with the pump.

Dr. Connell 10:13
Basically that the liver is a unique organ in that it has a dual blood supply. And we manipulate this information through the use of hepatic artery and fusion treatment. So there’s essentially two vessels which supply the liver, the hepatic artery and the portal vein. And liver metastases are perfused by the Patek artery, whereas what we call normal parenchyma, or normal liver tissue is perfused, primarily by the portal vein. So with hai therapy, we’re delivering the fluorouracil, which is a prodrug of 5FU or so into the hepatic artery, and we get very high concentration of the drug to the liver. And as I mentioned in the previous slide, it’s almost 400 times higher than those achieved by intravenous administration. And, and the important thing here is that essentially, the drug is entirely soaked up by the liver around 97% of the drug, it has a very short half life. So there’s minimal systemic exposure for patients and toxicity from the drug.

Dr. Connell 11:42
So I have two very brief slides just looking at some of the clinical evidence. And on this slide, we see the clinical evidence for HAI therapy in patients who have unresectable colorectal liver metastases. So the first study highlighted here was published in 2017. And basically, this was a case control study, which looked at the use of HAI with modern systemic chemotherapy combinations compared to systemic chemotherapy alone. And you can see even from the bar charts, there’s a there’s a difference there that’s quite visible between the purple bar, which is essentially the combination treatment and the orange colored, which is systemic treatment alone. And what was seen in this case control study is that median overall survival was doubled in patients, when they received combination treatment at around 32.8 months compared to our modern systemic chemotherapy options, which was 15.3 months. And this was even when conversion to resection was not achieved in patients. And this was statistically significant.

Dr. Connell 12:43
On the on the right side, then we see another paper and this was published in 2018. And this looked at like long term results from a prospective trial, and which again, looked at the response to hai therapy, and with systemic treatment, and basically, the overall tumor response rate to the combination of HAI with systemic chemotherapy was 73%. And there was a very high response rates in patients who were chemo naive. So when it was given in the first line, it was 86%, whereas in patients who were previously treated, it’s still very high, it’s 67%. And what we saw here is that 52% of patients were converted to resection with the combination treatment, despite the fact that the majority of these patients had what we would consider a high disease burden within the liver, and many of them had had previous chemotherapy.

Dr. Connell 15:19
I just briefly put up here, and this is really to January questions, you know, what’s the future for HAI therapy? Or how can we further advance what we know? And I think there’s two very important points to bring up here. And I know, these are questions that come up for me in the clinic is, you know, can we combine hai therapy with other systemic treatment options? One that’s very topical, you know, is kind of get it with Immunotherapy. And another would be, you know, some of these other newer drugs that are out there, you know, in particular for a patient to perhaps is her2 positive, BRAF mutated patients. So, you know, can we give them and right now, the honest answer is we don’t have the safety data to combine these drugs together. But it’s something that we do need to consider going forward in terms of trials. And, and also, I would like to highlight the HAI Consortium, and I think that’s a very important group. And it’s essentially a group of centers within the United States and also outside the United States, where we’ve come together, and we’re trying to generate trials. And there is a trial, which has been activated, which I know has been previously discussed here. And I think this is going to be a group that’s going to help propel forward future trials on hai therapy and and help all of you as well as patients in the future going forward. And it’s a very important collaboration to be able to replicate. I think what we’ve seen achieved at Memorial Sloan Kettering in particular with HAI treatment, and can we, you know, replicate that throughout the United States and more globally for patients.

Dr. Connell 17:01
So, what does it mean for a patient then to live with the palms, so just to get to some practicalities, so it does require a surgery to place the pump. And that’s important to say to patients and the majority of patients it’s placed at the time of an open surgery. In some patients where, for example, the colon primary, or the rectal primary has already been removed, and there is going to be no liver resection. There are some newer techniques such as robotic, placement and minimally invasive which are done by some of our surgeons. In terms of recovery. The honest answer is you can you can travel. And you can also continue to do most of the activities that you’ve enjoyed doing before. And during active treatment, the pump has refills every two weeks, you do not get drug every time it alternates between fluoxetine with heparin saline. And it is important to be mindful of the travel schedule. And I do say that to my own patients, because there is a residual within the pump, but you do not want the pump to run dry. So it’s very important to you know, mention any travel to your your treating physician and to try to accommodate that for patients as well. And otherwise, what I also want to highlight, and I mentioned this a little bit with the consortium, but there’s been a huge increase in terms of the number of centers since 2019, that are able to put in a level upon number one, and also for local refill centers. And this is something that is continuing to gain momentum. I think this is something that I learned, I’ll be honest with you during the COVID pandemic was so important for patients because there was huge difficulty in in people being able to commit to coming here every two weeks to New York at for pump refills and, and there’s a lot more physicians out there, and who who can now help assist with local refills. And that can be huge for patients, even if they’re not able to get the flux your dean locally, for example. But coming to coming to New York once a month is much better than having to commit to traveling every two weeks for example. And, and you know, it is important to also to mention that and we are trying to help train local oncologists also who maybe don’t have experience with the pump, but to be able to help some of some of you and some new patients who really want to commit to this to have refills locally. And then just to briefly mention, you know, some of the safety elements with fluoxetine. So, the anterior pump is indicated for the use of fluoxetine and it is contraindicated to the use of this and patients who have extensive extrahepatic disease or if you have limited liver function. And then always important to mention, you know some of the adverse events that can occur with the pump which are rare but serious and we can discuss them a little bit further in the q&a section.

Dr. Connell 19:59
So with that, I’m going to hand it over to Betsy, and we’ll go through the questions. So I’ll stop sharing here.

Betsy Post 20:08
Great, thank you so much. And then please, as we go along, if you do have questions, actually, I have one, two for the end, please do put those in the chat and we will get to those shortly. So the first question we have Dr. Connell is Why is HAI therapy generally done at the same time as systemic chemotherapy?

Dr. Connell 20:31
Yeah, so, you know, this question comes up a lot. And I think the important thing here is the there is a synergy between fluoxetine through the pump and giving it with systemic treatment in particular arena Tekin, and our EGFR inhibitors, but also importantly, we have to protect against the risk of extra hepatic disease, right. So if I have a patient and they’re on track to try to get to a liver resection, what is absolutely devastating for a patient is to get to a surgery. And the procedure is aborted because extra hepatic diseases detected and or for something to develop on a scan prior to surgery. So it’s really to help protect outside the liver, to allow us to focus on the treatment of the liver metastases with the flexibility and treatment.

Betsy Post 21:23
Thank you. How do you determine which systemic regimen that you’re going to use with the metastatic colorectal cancer liver met patients? And how does having a pump alter that?

Dr. Connell 21:35
Yeah, and so the first thing to say is that, while we typically and in the majority of patients give systemic chemotherapy with the HAI therapy, the dosing is automatically lower than it would be if a patient was receiving systemic chemotherapy alone. Because we have to balance the toxicities from using the two in combination. And so there is a different standard dosing of this systemic FOLFOX, for example, as opposed to somebody who’s on FOLFOX own in terms of what to use for patients. So there’s a few things to look at. I think the first thing is, in a patient who is previously untreated, the standard would be to use Folfox.

Dr. Connell 22:19
With the liver pump, and in somebody who possibly comes and they’ve had both treatments, what I take into consideration is I look and see, you know, what response, did the patient get to each individual systemic treatments previously, right? Did their cancer previously progress on Folfox? Do they maybe have stable disease on full theory, but they didn’t get enough of a response, and also the side effects that patients have had from previous treatment. So if somebody comes into me in clinic, and they have very severe neuropathy from previous oxaliplatin, I’m not going to jump to using that drug. So I think what’s important to consider is how the patient’s cancer has responded to previous drugs before the time interval that they’ve had from a particular regimen to perhaps another recurrence or something else developing and also the side effects for the patients from previous treatment.

Betsy Post 23:13
Thank you. The next question is, are there any situations where the HAI therapy might be done without systemic chemotherapy at the same time,

Dr. Connell 23:27
Um, very, very rarely, I have one patient since I began practicing here that I’ve done it in so I very, very select patients. In general, the preference is to give with systemic chemotherapy. Again, you know, in, in the scenario where I decided not to do it, it was a very detailed discussion with the patient about why we were not doing it and the risks of of not doing it together. But in general, it’s given. It’s given with some form of systemic chemo. And, you know, what I prefer for my patients is at least we give a single agent even if a doublet such as you know, 5FU with oxaliplatin or 5FU with Ironotecan is too much. And but as I said, it’s very rare that I do it. I’ve only done it once since I’ve been practicing here and had very real reasons for not doing systemic side effects may be possible in the liver area during HAI therapy.

Dr. Connell 24:28
Yeah, so the side effect profile is very different to systemic chemo. The two main things that I say to patients is we learned early on and many of the studies that were done with the liver pump the the risk of ulceration in the gut in the GI tract, so all patients are put on a medication to help prevent reflux. So pantoprazole protonix, and in patients who say to me that they’re having increasing reflux symptoms, for example, or they’re having some pain or discomfort, you know, just under the chest, and I’d have a very low threat To get an endoscopy to look for an ulcer, so that’s the first thing. But it’s much less common nowadays because we’re routinely giving protonix with it. I think what the big thing is, you’ve got to watch the delivery of blood work very closely. And in the majority of patients, you don’t come to clinic with any symptoms, right? You feel fine, you feel well, in general, patients feel better than they felt on previous systemic chemotherapy because okay, I’m still giving it but I’m giving a little bit less than you would have had previously. And what I always say to people, actually, when they come to me is it can be a little bit frustrating, right? If you fly to me from San Francisco, or you come from Canada, and you feel great, and then I see the liver enzymes, and I say, sorry, I can’t give the drug today or you know, we’ve had to give a few weeks holding off on the drugs. So the honest answer is we’ve learned from experience that we do have to be very mindful of the liver bloodwork, and then the majority of patients picked up on the bloodwork and the patient doesn’t have any symptoms themselves. However, in some patients, if you begin to develop any symptoms, such as jaundice, you know, anything like that, then a very low threshold to get your liver enzymes checked. And even if you’re local, to check them to see because that’s the biggest thing that we have to watch for is liver toxicity.

Betsy Post 26:16
How long does active treatment last? And what is the average number of treatments? And does this change? Does this change if the HAI therapy is being done before or after liver resection?

Dr. Connell 26:30
Yeah, yes. So the answer to the final question is yes. So if somebody has had a liver resection, and we’re using this as an adjuvant treatment, it’s six months of treatment. And then we stop. And in the majority of patients, we’ll get four doses in of the fluoxetine of the liver drug in the six month period, when we look at, you know, liver enzyme alterations, but we stop automatically at six months, and however many doses the patient has managed to successfully get that’s it. And in a in a person who is not resected, or I’m trying to convert to resections, when unresectable disease or in the conversion setting, there really isn’t a limit in terms of the number of doses that a patient can get. And the it really depends on how their liver is tolerating the drug, you know, what kind of response that we’re getting, you will have to make a change to the to the drug dosing. And what I’ve seen in practice is that typically, that happens around two to three months into treatment. It’s not uncommon, that it could happen even after the first dose, but there will be some dose modification. And patients can still respond on low doses. And that’s also important to say, because again, I also acknowledge that, you know, really, you’re committing to come in here for these treatments or to hai center. And it’s very disappointing, if you hear you’re getting a quite a significant dose reduction. And but you still respond to this. And it’s different to what we know about the dose reductions that are done with systemic chemo.

Betsy Post 28:04
Thank you. Is it possible to do treatment again, with the pump later on, if needed? 

Dr. Connell 28:14
Yes, exactly. Yes, you can. And this is why, you know, our, our preference is for patients to keep the pump, right, because particularly, what I would say to patients is, if you are using it as adjuvant therapy after liver resection, or you’ve been converted to resection from the pump, at the time of surgery, the recommendation, so your NED at that point, right is at least two years. Ideally, we prefer patients to keep the pump in longer. But the highest risk period for recurrence is the first two years and the rationale behind that is because the pump is not something that can be put back in right a little bit like a metal porch, right? So we want to keep that option open. Particularly if, if it’s helped you get to your surgery, number one, and you know, so that we can use it again. So absolutely, yes, you can use the drug again.

Betsy Post 29:11
Thank you already answered the next one, which was does the pump stay in when active treatment is done? And for how long?

Dr. Connell 29:18
Yes. Yeah. Yeah. And so yeah, and this question comes up and the honest answer is as well what I would say is i i Never tell someone to take a pump out I wait for them to tell me that they’re ready for it to come out because I think it’s a very personal decision. I think it’s something that for many patients has been you know, revolutionary, I guess and and I think, you know, we can educate and guys and that but it has to feel right to you as a patient to know when is the right time to remove it. If somebody really wants it out within six months. I’m like, please keep it for two years but beyond that, I really leave it up to the patient’s decide

Betsy Post 29:59
Are there other drugs ever used in the pump like oxaliplatin?

Dr. Connell 30:05
Yeah, so, oxaliplatin has a very low extraction rate into the liver. It is used in Europe because they have a slightly different device there. We don’t routinely use it here. But we do use Mitomycin and that’s something I referred to briefly during my talk. And I have seen patients who perhaps are beginning to develop some resistance to Flox your deen or maybe are beginning to run into more issues with their liver enzymes. And I’ve used Mitomycin in those patients and seen you know, some very good responses with the middle myosin what I would just say about that is you can give it in combination with fluoxetine. So you can give both drugs at the same time if your liver enzymes are good. So if the liver bloodwork is good, if the liver enzymes are high, tickling the outsource or perhaps the bilirubin, and that it’s safer to give Mitomycin on its own, but that’s typically our second drug that we use. We don’t give oxaliplatin.

Betsy Post 31:09
What are the causes for the mitomycin following HAI therapy with the traditional treatment?

Dr. Connell 31:19
Why would we give it right?

Betsy Post 31:21
I think you already spoke to that. 

Dr. Connell 31:24
So yeah, yeah. So I think if you’re getting a slowing down in response, possibly to flux, your routine, maybe you are getting some response, but you’re beginning to run into some of these liver toxicity issues. And so they would really be the main reasons that we do it. And really, I would use it in a situation where it’s liver only progression, of course, like I wouldn’t use it if there was signs of anything happening

Betsy Post 31:47
Um, and then since I’m not an oncologist, I might mess up these names. But what are the views on the use of Bev, which I know is Avastin. So we’ll take that one first. The new third line or a drug that was just FDA approved for colorectal cancer, liver Mets, or the EGFR inhibitors. So what are the views on those three and maybe address them separately? Because I know it could be different after the HAI therapy when the pump is running glycerin.

Dr. Connell 32:18
Okay, so I’ll start with EGFR inhibitors first, because that’s probably the easiest ones you can give EGFR inhibitor is at the same time that you give fluorouracil safe to do works very well with the liver pump.

Dr. Connell 32:32
And you can also give it after liver treatments. So there’s no limitation at all with EGFR inhibitors and actually works very well with with FUDR, or Avastin is something that we’d urge early on, that should not be used the same time that we’re giving fluoxetine. So it’s it’s a combination, so it should not they should not be used together. And but a patient can have Avastin or Bevacizumab later on, if you’re simply just getting glycerol through your pump. And so, if for example, I have somebody who the liver is still no evidence of disease, there’s, you know, issues arising outside the liver in the lung, perhaps or lymphnodes. Have I given Avastin? Absolutely I have, I generally prefer to try to delay the use of Avastin further out from using the liver drug because I have seen in some patients some delayed issues with billary complications if I’ve tried to use the Bevacizumab a little bit too quickly after stopping the liver pump treatment. And but yes, you can use them separately but not together and then forget never the honest answer is we don’t know yet. Because it’s such a new drug definitely would not use them together. And I think you know, you would think along the same lines as you know, what we do with Stivarga, etc. You know, they can be given but not together. And the honest answer is and I kind of led to this during my sliders, I really reserved the use of any of these drugs too much, much later on for patients. I think if you can do something like long ablations or radiate, I think you’re helping the patient more than jumping to any of these newer, third fourth line drugs that are approved.

Betsy Post 34:17
Thank you. And these are questions that we see in Colin town all the time, and these were the most frequent questions that I received for you. So these have to do with Y90 So if a patient has had Y90 How does this affect their ability to receive HAI therapy after?

Dr. Connell 34:38
Yeah, okay. So this comes up quite a lot. The honest answer is if I see a patient before a Y90 Maybe they come with a second opinion we usually prefer to give the pump before Y90 that’s the honest answer. So usually what I say to patients is, you know, pump first and any of these proceed procedures like Y90 or radiation I would reserve for later on. And have I had patients who’ve had y90 And I’ve given pump treatment to absolutely, I think we have to look at those cases individually. And it’s something that we would show at our tumor board. And we would really look at the extent of the Y90, for example, how the blood vessels in the liver look after the Y90.

Dr. Connell 35:24
Often you need to dose reduce the flux your routine a little bit faster in those patients so I can get the drug in for the patient, but I can’t get as much drug in. And but I’ve had people respond after y 90 I think our preference is to do pump first.

Betsy Post 35:45
If a patient has HAI therapy, and then does Y90? Would the patient be able to use the HAI pump again, if it is still functional?

Dr. Connell 35:56
Yeah, and so this is an interesting one. I haven’t personally ever done that myself. I think from a technical point of view, it would come back to what I said previously, is that you’d have to really look structurally at the liver and see, you know, there’s there’s newer Y-90 techniques out there. And I know whether our interventional radiologists here they do more selective Y90 So if perhaps, you know, there was a regional Y90 And then you’re trying to treat the rest of the liver. Technically, you could. I think just with with my own practice, and the way that I view it, because I keep Y90 for Later on, it just hasn’t worked out that way with the patients that I’ve seen. But again, I think this is something that you would have to have the right imaging, it would have to be viewed as a multidisciplinary team, whether that’s the right thing for the patient, you know, including an interventional radiologist, including a radiation oncologist right, is radiation safer than Y90 A surgeon and a medical oncologist to decide what’s the right thing for that particular person.

Betsy Post 36:56
Some additional questions have to do with transplants. This is something that we’re hearing more and more about, especially for unresectable disease, obviously, and we have patients a lot of times that are making a decision, sometimes between the pump or transplant, but something that we’re hearing now is the question first, could the pump be used as a bridge to liver transplant?

Dr. Connell 37:18
Yeah, so this is very typical? I think without intentionally setting out that way. And I’ve had some patients who’ve done very well with transplantation after pump treatment, I think the tricky thing about the transplant process is that it’s a long process for patients. Right. So my own experience with my patients has been is that sometimes they’re waiting like 12 to 18 months. And I’m trying to control everything with the pump at the same time. So I have used it but not intentionally. I’m on discussions with transplant centers. And speaking with surgeons here, this is something that I think we’re going to need to study. And we’re going to need to collaborate on to see if we can help more patients by combining the two techniques.

Betsy Post 38:37
Another question, how do you consider the option for liver transplant as part of your overall treatment plan or approach for patients?

Dr. Connell 38:47
Yeah, so. So when I see patients, you know, this can often come up. And I think with transplant, what I say to people is we got a real sense of how the pump is helping a patient in unresectable disease, like, you know, about six months in, you know, look, and you’re talking back and forth with the surgeons, you know, do we think that we’re going to be able to convert to resection here? Do we have any of these options like why nine tear or radiation? And I think it’s always appropriate to get an opinion from a transplant center, and particularly if it’s something that the patient themselves is questioning, right, because you want to hear directly. And there’s a little bit of bias right between different different specialties and obviously I’m very Hai and but I’ve certainly collaborated with transplant centers, and then you know, when somebody is listed for transplant in practice, what I do is I follow what they want me to do, so I don’t change any treatment, you know, they tell me what they want to do. The important things about transplant is a few things. So you cannot have any extra hepatic disease obviously so there can be no evidence of extra hepatic disease. And the second thing is that the primary tumor has to be removed.

Dr. Connell 40:03
So, you know, they would be the two things. But if you have liver only disease and and resection is not feasible, and you’ve heard that from the liver surgeon and you’ve heard that from your medical oncologist then then I do think transplant is something that needs to be considered. And they removed the pump at the time of transplant as well. 

Betsy Post 40:26
So is there data available to show how successful ATI therapy is? And I know that we did talk? You talked about that earlier, but I didn’t know if you wanted to elaborate on that a little bit more.

Dr. Connell 40:39
Yeah, so we do have data. And I’ve shown some of the data here, I think what’s important is that we need more randomized to data. And I think, you know, that’s what the consortium is going to help with and why we’re trying to collaborate with other institutions. And I think trying to address this question of, is the pump so successful? Because it’s given here in New York or you know, Kansas, can I get the same level of care? Or in Chicago, or, you know, Atlanta? And I think the honest answer is there’s so much more knowledge out there about the pump. And we do need to do more trials. And also, I also mentioned this as well, there’s so many newer drugs out there, right. And patients want to know can kind of get them together, is it safe to get them together? And this has to be done in a trial setting.

Betsy Post 41:27
So another question we get quite a bit. So now that Dr. Kemeny has retired, how was care being distributed for patients that are being seen at Memorial Sloan Kettering?

Dr. Connell 41:39
Yeah. And so what I would say about that is, honestly, all of us can can can do pump treatment, I think a huge part of Dr. Kennedy’s legacy. What’s visible to patients and caregivers is is what she did for you, right? Understandably, a huge part of her legacy for us at Memorial is the teaching and training that she gave to us. And, you know, she was a phenomenal mentor to me. And to many of my colleagues.

Dr. Connell 42:10
All of our practices differ a little bit. So some of us do more pump than others. But honestly, all of us can do pump in terms of her practice. And it’s been divided between Athol I think for for active patients, understandably, because I was mentored under her I have many of her patients. I think, what’s also important to say, though, is that, for any of you who have, you know, some complex decision making, there’s something to be to be, you know, figured out, you know, is it now the right time to think about y 90, you know, have I achieved what I can with the pump, that’s never a decision that’s made in isolation by an individual, whether that’s a medical oncologist, it’s our tumor board is a huge resource for people and, and that’s often what I what I see myself as like, You’re not coming here to memorial for me, you’re coming for the expertise from the whole group. And never think that a decision a very important decision like that, look, will I say to this patient that you should go and get a transplant opinion, you’re not going to hear that just for me, I’m going to speak with my surgeons I’m going to speak with with them, and we’re going to show your case at the tumor board. And I think that’s very important to know, is that there’s huge collaboration amongst us as medical oncologists, and also multidisciplinary team involvement in any major decisions for patients.

Betsy Post 43:31
I know that you spoke about the Consortium, and that all the pomp programs, especially since my team that have opened up, but How can patients across the country get good access to HAI therapy?

Dr. Connell 43:44
Yeah, so I think there are more centers, who are implanting the pumps, number one, and also so many more centers where, you know, they’re able to assist with with local fields, I think the consortium is really helping with that. I would also say that there’s a huge collaboration between us, you know, I definitely speak with medical oncologists at other institutions. You know, I relied on mentoring, when I started off with this, and I try to share what I’ve learned in the nuances, you know, with oncologist with other centers, I think, when you start off, you know, what I always say to people is, you have to be comfortable with the person that’s treating you, right. And whether that’s having a pump or not having a pump, I think, number one, you have to be comfortable. So, you know, and you also have to think from a practical point of view, you know, look, if financially and with my family or my work commitments, is it feasible for me to fly up and down to New York every two weeks? And for many patients, it is for others. It’s not. Do I have a local doctor who can do this? Did I did We did our personality match? You know, and but I think there is so much more knowledge out there nowadays and there’s also huge camaraderie between us and sharing of knowledge. And, I think the consortium and the trials and everything that’s going to come out of that is going to further reinforce that for patients.

Betsy Post 45:11
One more question, and then we’re going to take the live questions, we have quite a few. How does the start of that new pump trial impact the ability of new patients to receive HAI therapy?

Dr. Connell 45:23
Yeah, so it’s a very relevant question. And you know, what I would say about the pump trial, it’s a very, very select group of patients, right? It’s a very important study, right to help answer this question, in a randomized setting of, you know, conversion to resection for patients with HAI versus modern systemic chemotherapy. So it’s for patients who’ve had more than three months, but less than six months of systemic chemotherapy in the first line. So it’s a very small group of patients. And the honest answer is the reason that we’re doing that is because we don’t know the question, right, we are the answer, we wouldn’t be doing it if we already knew that one was better than the other. And that’s important to say about any trial. If you’re a patient who is untreated, you had no chemotherapy, you can have a pump off trial, if you’ve had more chemotherapy, like you’ve had a year of chemotherapy, you don’t, you don’t qualify for the trial. So it’s a very, very select group of patients. And that will be explained to you as well, in the in the in the clinic setting.

Betsy Post 46:30
So moving on to some of our live questions, we have one, is there a certain temperature that you have to keep your body under while you have a pump?

Dr. Connell 46:42
Yeah, so this question comes up quite a bit, you know, I think you have to be sensible, right? So he will speed up the rate of infusion of the drug. Hot tubs are a no, no, you can get in a swimming pool. And so body temperature can affect us, I don’t give anyone like a specific number. But I just say like, you have to be mindful of it. And I have a patient who said they have a hot tub with that, put it on regular temperature. So you know, swimming, and all of that is fine. But sitting in heat, you don’t want to put heat pads directly on the pump. If you have pain in your back for another reason, you can put heat out there, but you just want to do want to put it directly over the pump.

Betsy Post 47:25
Is it true that you can’t lift more than 10 pounds when the pump isn’t?

Dr. Connell 47:31
Yeah, so again, this comes up quite a bit. So usually I say around 15 pounds to patients. In the beginning, I think you have to be very mindful of that similar with any surgery to be honest with you. Over time, honestly, what happens is you have a very good sense of your pomp and also scar tissue forms. And so I tell patients that, you know, using a binder, you know, be sensible. But a lot of people say, Well, you know, my toddler is 30 pounds, you know, and I’m never gonna say to somebody, you can’t lift your child up, you know. So I think within reason, and I think if you’re, you know, the further out, you get the sense you have your palm, the binder, scar tissue, and, and, you know, for lifting children in the beginning, I usually say to people, you know, sit down and lift them up onto your knee, you know, things like that. So I try to be creative with how you do things. But I do think we have to be practical in that regard. And the concern about the weight lifting is the connection between the catheter and the pump, and also the risk of, you know, the pump flipping, and the more secure it is over time that the lower the risk of that

Betsy Post 48:39
Um, there’s a question about the drug and mutations. And I know specifically, we do have some BRAF patients here. So question, there’s a question about, is the HAI therapy equally effective for all mutations?

Dr. Connell 48:56
Yeah, so it’s a very good question. I think what I would say to you is, is that we do use the pump and in all patients, I certainly have myself patients who have BRAF mutations, and I’ve used the pump, and I’ve seen some very good results with it. So I wouldn’t discriminate based on that. And but I think it’s something that we’re going to need to study a little bit further to see how we best serve people going forward. But I definitely have patients who’ve done well. And you know, maybe later on I’ve used the combination I mentioned earlier, such as graphics to toxic map, and but if they have liver only disease, we still put pumps and we still get flux your routine and I’ve definitely seen good responses. I have a patient who was probably an outlier but from from early 2019, and still NED

Dr. Connell 49:47
and had, you know, resection, had liver pump to get your resection and as BRAF mutated, you know,

Betsy Post 49:55
right. I think you answered this, but I’ll ask it for those pursuing liver resection, is there a recommended number of fudr treatments from the pump before considering surgery?

Dr. Connell 50:10
And so the honest answer is there isn’t a set number per se, if somebody has unresectable disease. So what we do is we scan every two months because we want to keep a close eye on the response that we’re getting and how the liver is tolerating it, right? So you’re scanned every

Dr. Connell 50:29
which is a little bit different to the adjuvant in the adjuvant setting, you’re scanned every three. But what I usually say to people is that honestly, at two months, it’s it’s not very common that patients are ready for surgery, it’s typically around the four to six month mark, but there isn’t a set number is really depends on the location of tumors, the technicality if somebody has liver, you know, bi lobe disease, so both the right and the left side involves the surgeon will say to me, Look, we need to do these portal vein embolization, you know, certain procedures to help get to a second stage liver surgery. So the some of those factors to come in. But there’s no hard and fast rule with the number of doses that a patient has to have

Betsy Post 51:13
HAI pump decisions require very close coordination between the medical oncologists and surgical oncologist Are there any best practices from that cross specialty communication that you would highlight is beneficial to apply? Even beyond the HEI application?

Dr. Connell 51:31
Yeah, so, you know, what we’ve learned to serve patients best is that multidisciplinary involvement is so so important. Right? And, and I kind of, you know, said that earlier on, like, any major decision point you need to think about, you know, how am I helping the patient right now? And also, how is this going to affect what I want to do in the future for the patient? Right. So in my own practice, here, I do my clinics alongside the surgeons at for that reason. And you know, when I asked some of these questions, we also have very heavy input from our interventional radiologists. And I think that’s very important is to try to get the different options there. And sometimes there is there’s two options, right maybe let’s say for the liver, it could be resection or it could be ablation, and then we can see both and help make the decisions by getting the input from from both specialties for example.

Betsy Post 52:32
Are there restrictions on jogging and working out?

Dr. Connell 52:37
Okay, so what I would say about that is if you put 20 of us in a room, a mix of surgeons and medical oncologists, everybody would say something different and it’s very controversial. And I allow my patients to light jog and the the concern again is really the connection of the catheter to the pump. And again, what I say to people is exactly what I said weightlifting you know, if someone comes in to me and you know jogging is your is your your cam time, you know, your therapy so to speak. You know, it’s very hard to say to somebody, you know, don’t jog and but I say you know, try to be sensible about it, have a binder on Wait a while and I do allow patients to do like jogging. The surgeons do lap people jog and there’s other medical oncologists who say no, and we love stationary bike. We love the peloton. That’s, that’s probably the safest thing that you can do and the best thing and a good form of workout. But yes, I do say to patients, they can jog.

Betsy Post 53:41
So if there is a patient that has, for example, ovarian or peritoneal disease, but the patient was potentially able to have all of that removed. Could they still get pumped?

Dr. Connell 53:56
Um, so for over a yes. So if you have liver and ovary because we know that colorectal metastases to the ovary, are quite resistant to chemotherapy, so in general, the bias is to lean towards surgery in that situation anyway. So you would often do if you can do a liver and you would also remove the ovaries at the same time. So yes, with peritoneal disease, there’s a little bit of pause. I’ll be honest with you. The tricky thing about peritoneal disease is that you often can’t fully appreciate peritoneal disease on scans. And and it’s only at the time of surgery that you really have an understanding. And I’ve had some patients where perhaps there’s been like limited peritoneal disease, you know, a year ago it was removed and maybe they come looking for a pump. And and usually if there’s, you know, a period of time, typically a year, year and a half, not thing happening in the parish name again, then, you know in select cases we’ve put pumps in. And but I wouldn’t say to you upfront that I’ve put a pump in for a patient when they have active peritoneal disease at the same time.

Betsy Post 55:14
For every two to three months scans, do you do CT MRI, and I’m gonna throw in there you PET scan stew? Might as well add it in.

Dr. Connell 55:24
Yeah, and, okay. Um, so in that regard, what I would say to you is I started off using CT and patients. So I do routinely, CT chest, abdomen and pelvis. Over time. From looking at the CT scan, you understand with the individual patient, whether you’re seeing things clearly in the liver or not, if not, particularly in patients who maybe have, you know, a lot of chemotherapy prior to the pump being placed, because the chemotherapy changes the texture of the liver, what we call like fatty liver change, or sclerosis. So in those patients in MRI may give additional information. So the honest answer is, my starting off rule is CT only, I’ll involve an M or liver if I feel like I’m not seeing things clearly with a CT. And I really don’t routinely use a PET scan, unless I get to a point in a patient where a specific question has come up on a on a CT, for example, I do a patch, and I see that the patch is giving more information than the CT has. Similarly, if I do a patch on a patient, and I see that I’m not getting anything different from it, then I don’t routinely follow with Pat. And I think that would be the standard approach. For most patients. The tricky thing with PET scans is there can often be you know, false positive things on a PET scans and something lights up. And it’s it’s not anything related to the cancer and then it causes, you know, a lot of concern, understandably. Yeah, so that’s how I would view it. But I do have some patients where I know that only MRI shows that are only pet shows that and then once I learned that with the patient, then I continue to use that imaging modality. But I still always do my CT as well.

Betsy Post 57:12
We have one more question about I think exercise I see here. What about horseback riding? I’m a serious equestrian.

Dr. Connell 57:21
Yeah, so this came up for me recently. The issue with with horse riding is the bouncing activity. Right and the concern for the catheter? Again, I don’t think it’s a complete contraindication I think, and I know I’m repeating myself a lot but wearing the binder, a similar lead to what I’m seeing with light jogging. I mean, you can I don’t even know the word for isn’t trotting. for horse riding, you know, you have to be mindful of that. And but I wouldn’t, you know, I wouldn’t say you can’t do it again, if that’s something that a patient is passionate about, and it’s their form of relief, or escape from what’s going on, then I think that’s important to consider. So have a binder be mindful. That’s what I would say.

Betsy Post 58:07
We just have two or three more. So how would you know if there’s a problem with the connection from the pump? Perhaps from over lifting, etc?

Dr. Connell 58:19
Yeah, the honest answer with that is that most patients don’t know. And it’s picked up on scans. That’s the most common scenario. And that’s really where we see it. If somebody has, you knows, for example, they’ve had a trauma, you know, so So I had a patient a few years ago, and they were in there on a regular bicycle, and they flipped over the handlebars, and they were like, This doesn’t feel right, you know, so I scanned and you know, there you knew there was some incident proceeding, and you would check for it or they had pain afterwards. But the honest answer is in the majority of patients picked up on scans and you don’t feel any difference.

Betsy Post 59:03
Let’s see, I know I’m gonna mess this this word up.

Dr. Connell 59:08
So what are the thoughts around using the capecitabine with the pump while receiving radiation to treat the primary replacing traditional systemic treatment? Okay, yeah, so this comes up quite a bit. So when patients have a rectal tumor and you know, you can treat them with chemo radiation. So we do, you know, and you know, that’s in terms of a rectal tumor, the surgery is much more life altering. So if you can effectively get a complete clinical response or fully treat the rectal tumor than chemo radiation is recommended. What do I do in my patients? So the issue with Capacetibine Xeloda is that it causes more increase in liver enzymes, and it can affect the dosing of the fudr. So what I do for patients is if

Dr. Connell 1:00:00

We have a rectal primary and we’re doing chemo radiation. And we’ve just put a pump in for liver disease, you can give the fudr you can give the liver treatment during the chemo radiation. But instead of using the Xeloda and or capecitabine of being I use fluorouracil which is sort of the old way that they that they used to do chemo radiation. And because again, I want to try to maintain the higher doses in the pump and keeps it being tends to interfere with that more. So.

Betsy Post 1:00:36
I think I got to almost every question, one of my questions that I have, if I can just sneak one in I know it’s 802. But with all the centers opening up, I feel like we’re seeing some oncologists are using the Urso dial and some are not. And I don’t know if you feel comfortable speaking to that, and how you use it in your practice and how the decisions made to use that or not?

Dr. Connell 1:00:59
Yeah, it’s a very good question. I mean, I think what I would say to you as well is there’s even differences in the practice here at Memorial as well. I, I use it quite early on in patients, because I think, you know, the two ways we manage the liver inflammation are the steroids through the pump at the time of the flush as well as versatile. And, and in the long term for patients being on steroids continuously. You know, there’s this kind of late side effects with that there’s the weight gain that comes from steroids, there’s a few patients where versatile can be a little bit tricky. So sometimes patients can notice the very loose stool. So if I have a patient who’s struggling with, you know, diarrhea issues or anything like that, from arena Tekin, or even five floor yourself, I kind of hold off on the earth a dial, but I tell them why I’m not doing it, you know, but I do tend to use it early on. And I also tend to keep it on board longer, even after I’ve weaned down the steroids in the pump, and I have someone off treatment, because I think it helps with the liver inflammation, I typically start off on twice a day in some patients, you may have to go up to three times a day. But again, if you even select 10 oncologists here at Memorial, everyone would do something a little bit different. But I give the options to patients. And I also explain, as I said, when I don’t use it and what my concerns are for that particular person.

Betsy Post 1:02:31
Well, it’s 8:04. And I think we have gotten to most of the questions. There is one here that I’m not sure we may have to get back to because it’s you know, the top centers for ATI. And with so many new centers that have opened up since 2019. I think by volume, we’d have to kind of look into that to see who they are. I know Duke is one of them. I know they’re very, they’re a high volume center now. But with the opening of the consortium, I know we have a lot more centers throughout the US. So I can take that offline. And definitely I can talk to the folks at inteiro on that as well. Just about the volume at the other centers. But yeah, so I just wanted to say again, thank you so much for your time, I learned a lot. And it was so good to hear just from a medical oncologist. So in addition to Dr. Kemeny and hear how you’re using it, your practice, and I learned a lot of just about the trial and other things. And your take on that. And I really appreciate it. I know you were so generous with your time and answering all of these questions for the patients. And we really all appreciate it. So thank you so much. And I know we’ll be in touch if we have additional questions. So thanks for everybody that attended tonight and thanks for all your participation. We really appreciate it. So have a great evening. Thanks again. And we’ll see you soon.

Dr. Connell 1:03:46

In DocTalk, Dr. Louise Connell from Memorial Sloan Kettering discusses HAI for metastatic CRC with Betsy Post. Recorded in January, 2024.

Betsy Post 00:01
Welcome, everyone. Thank you so much for joining us this evening for our latest DocTalk. I’m so pleased tonight to be with us here for our COLONTOWN DocTalk. Dr. Louise Connell from Memorial Sloan Kettering Cancer Center. Dr. Connell, I think is very well known in COLONTOWN. So if you’ve been around for a while, you definitely know her name. If you are familiar with liver Mets, and especially if you’re interested in the hepatic pump, I know that you definitely have seen her name. And our groups such as Liver Lovers Lane and HAI Pump People, I’m sure that we have some of her patients here tonight to support her as well. So we are so thankful for your time, Dr. Connell, especially for doing this after hours so that we could get maximum participation from our patients and our caregivers. So thank you, again, for agreeing to do this, we’re really excited to hear from you on how you treat patients specifically with the pump. I know that you have some things about the future about the pump, which is really exciting. I’m very excited to hear that. And then we did have patients and caregivers submit questions in advance. So we will get to those questions at the end of Dr. Connell’s presentation. So at the end of her talk, she will, we’re going to do some Q&A based on some questions that we received in advance. As she is presenting, we would ask that you please stay muted so that we can make sure we’re being respectful of her presentation her time, but do put your questions in the chat. So please do use the chat feature to submit your questions. And we will get to those live questions at the end of the presentation and the pre-submitted Q&A. So with that again, Dr. Connell, thank you so much for being here. The floor is yours.

Dr. Connell 01:55
Okay, thank you, Betsy. And first of all, I just want to say thank you very much for the invitation to speak here tonight to you all. COLONTOWN is is a resource that I hear so much about from my patients, and a platform that I think provides so many of you with information that you bring to the clinic, to advocate for yourselves and to, you know, advance your care. And I think, you know, it’s been such an important resource that, you know, if there’s any way that I can help provide additional information, particularly about the liver pump. This is an honor to be asked to do this. So tonight, my slides section is small on purpose, because I really wanted to give you all an opportunity to ask questions. And I would encourage you to submit any questions that you have for me. I did just want to provide some background on you know where we are today, today in terms of metastatic colorectal cancer treatments, and in particular, the role for HAI therapy. I think many of you already know much of this information. But in particular, for patients and caregivers who perhaps are new to this or maybe considering a pump, I did want to provide just some background slides on the pump treatment.

Dr. Connell 03:15
I’m going to just advance my slides here. So first of all, I just wanted to put up this disclaimer to acknowledge some of my consulting work. But truly the presentation today is purely for informational and educational purposes. And it’s really based on my clinical experience with patients and my knowledge in terms of pump management.

Dr. Connell 04:16
And at diagnosis, we see approximately 20% up to a third of patients will have liver Mets at diagnosis whereas the majority of patients will go on to develop liver metastatic disease during their follow-up. The question is what are our treatment options nowadays for metastatic colorectal cancer and, I’ll just briefly run through this on this slide on the next slide. But essentially we have or our cornerstone standard of care chemotherapy treatments, and we combine these drugs with biologics. I think increasingly we’re hearing about biomarker-driven approaches and I’ve highlighted here are the four key targets that we look for in patients who are newly diagnosed being microsatellite status. Their RAS status, BRAF status and HER2 status. 

Dr. Connell 05:00
And, of course, you know what I think I’ve always in patients because of the work that I do is the role for local regional approaches and particularly in patients who have liver only disease or liver dominant disease and looking to intermix this and combine it with my chemotherapy drugs and with biomarker-driven approaches to get the best outcomes for patients. So in terms of patients with liver dominant or liver only disease, you know, I consider resection, ablation, of course, hai therapy and also y 90 as well as I should mention radiation treatments to the liver. And also, I think local regional approaches have a role to play in patients who have lung metastases or illegal metastatic disease which is out where you may have an isolated tumor or a small tumor. And you know, maybe you can be more localized with your treatment approach and for the lung that would include ablation resection and also stereotactic radiation. D=So the progress that has been made in the last you know, 50 years is phenomenal. Unfortunately, a long time ago, when patients were diagnosed with metastatic colorectal cancer, and there were no drug options, the recommendation was for best supportive care and, then over time, really, it was single agent 5FU. And this slide shows where we are today in terms of drug treatments. On the left hand column, you really see our cornerstone drugs, which is the Fluorouracil, Capecetibine have been being the oral version Irinotecan and oxaliplatin, and this is what we all know, as, you know, fall Folfox, Folfirir, the combinations of these drugs, looking at VEGF inhibitors such as Bevacizumab, EGFR inhibitor, centuximab, or, or panitumumab in patients who are RAS Wildtype and then on the right column, we see the newer drugs that are out there, right. 

Dr. Connell 07:01
So with patients who have BRAF mutated colorectal cancer, the combination of NRAS and Centuximab, HER2 is now you know, very to the fore in terms of drug therapy, which a centuximab and trust panitunamab. And then there’s been a lot of focus recently in terms of MSI, high disease and Immunotherapy options. And what I always say to my patients in clinic is that this is very important to determine for patients, but it’s such a small group of patients that we see.

Dr. Connell 07:21
And then the third line drugs you know what I would say briefly about these drugs Regorafenib Taz 102, which I typically combined with Bevacizumab, or for Fruzaqla is that these are drugs that, you know, have limited clinical benefit, and they have a high side effect profile. And I’m very selective in terms of which patients I decide to use these drugs for. More commonly, I would personally use TAZ102 with Bevacizumab and but that differs from patient to patient. And what I’ve highlighted on the far right is what I consider the star of the show which is liver directed treatment. And I think it’s so important to think about it in our patients and the core drug that we have is fluoxetine, and then we use Mitomycin you know, further and, you know, down the line for patients or if they’ve, you know, beginning to develop progression on fluoxetine, and I can talk about that a little bit more in the question and answer section.

Dr. Connell 08:52
So what is a Hepatic artery infusion treatment so traditional chemotherapy is delivered through through a vein. You know, in colorectal cancer, we typically have a meta port in place because of the fight through fluorouracil being given in an infusional form. The drug travels through the body’s bloodstream to reach the liver, and only a small portion of the drug will ultimately reach tumors in the liver. And as many of us who are patients and on treatment know, and it comes with side effects and typically, you know, issues such as diarrhea, mouth sores, you know, low blood counts such as neutropenia has. The benefit of hepatic artery infusion therapy is that it’s delivered through a pump first of all, which is implanted just below the skin in the abdomen. The drug is administered through the hepatic artery, directly to tumors in the liver, and it delivers up to 400 times a higher drug concentration to tumors in the liver. So we’re really getting to directly to the problem. And this is just a graphic showing. You know how that works with the pump.

Dr. Connell 10:13
Basically that the liver is a unique organ in that it has a dual blood supply. And we manipulate this information through the use of hepatic artery and fusion treatment. So there’s essentially two vessels which supply the liver, the hepatic artery and the portal vein. And liver metastases are perfused by the Patek artery, whereas what we call normal parenchyma, or normal liver tissue is perfused, primarily by the portal vein. So with hai therapy, we’re delivering the fluorouracil, which is a prodrug of 5FU or so into the hepatic artery, and we get very high concentration of the drug to the liver. And as I mentioned in the previous slide, it’s almost 400 times higher than those achieved by intravenous administration. And, and the important thing here is that essentially, the drug is entirely soaked up by the liver around 97% of the drug, it has a very short half life. So there’s minimal systemic exposure for patients and toxicity from the drug.

Dr. Connell 11:42
So I have two very brief slides just looking at some of the clinical evidence. And on this slide, we see the clinical evidence for HAI therapy in patients who have unresectable colorectal liver metastases. So the first study highlighted here was published in 2017. And basically, this was a case control study, which looked at the use of HAI with modern systemic chemotherapy combinations compared to systemic chemotherapy alone. And you can see even from the bar charts, there’s a there’s a difference there that’s quite visible between the purple bar, which is essentially the combination treatment and the orange colored, which is systemic treatment alone. And what was seen in this case control study is that median overall survival was doubled in patients, when they received combination treatment at around 32.8 months compared to our modern systemic chemotherapy options, which was 15.3 months. And this was even when conversion to resection was not achieved in patients. And this was statistically significant.

Dr. Connell 12:43
On the on the right side, then we see another paper and this was published in 2018. And this looked at like long term results from a prospective trial, and which again, looked at the response to hai therapy, and with systemic treatment, and basically, the overall tumor response rate to the combination of HAI with systemic chemotherapy was 73%. And there was a very high response rates in patients who were chemo naive. So when it was given in the first line, it was 86%, whereas in patients who were previously treated, it’s still very high, it’s 67%. And what we saw here is that 52% of patients were converted to resection with the combination treatment, despite the fact that the majority of these patients had what we would consider a high disease burden within the liver, and many of them had had previous chemotherapy.

Dr. Connell 15:19
I just briefly put up here, and this is really to January questions, you know, what’s the future for HAI therapy? Or how can we further advance what we know? And I think there’s two very important points to bring up here. And I know, these are questions that come up for me in the clinic is, you know, can we combine hai therapy with other systemic treatment options? One that’s very topical, you know, is kind of get it with Immunotherapy. And another would be, you know, some of these other newer drugs that are out there, you know, in particular for a patient to perhaps is her2 positive, BRAF mutated patients. So, you know, can we give them and right now, the honest answer is we don’t have the safety data to combine these drugs together. But it’s something that we do need to consider going forward in terms of trials. And, and also, I would like to highlight the HAI Consortium, and I think that’s a very important group. And it’s essentially a group of centers within the United States and also outside the United States, where we’ve come together, and we’re trying to generate trials. And there is a trial, which has been activated, which I know has been previously discussed here. And I think this is going to be a group that’s going to help propel forward future trials on hai therapy and and help all of you as well as patients in the future going forward. And it’s a very important collaboration to be able to replicate. I think what we’ve seen achieved at Memorial Sloan Kettering in particular with HAI treatment, and can we, you know, replicate that throughout the United States and more globally for patients.

Dr. Connell 17:01
So, what does it mean for a patient then to live with the palms, so just to get to some practicalities, so it does require a surgery to place the pump. And that’s important to say to patients and the majority of patients it’s placed at the time of an open surgery. In some patients where, for example, the colon primary, or the rectal primary has already been removed, and there is going to be no liver resection. There are some newer techniques such as robotic, placement and minimally invasive which are done by some of our surgeons. In terms of recovery. The honest answer is you can you can travel. And you can also continue to do most of the activities that you’ve enjoyed doing before. And during active treatment, the pump has refills every two weeks, you do not get drug every time it alternates between fluoxetine with heparin saline. And it is important to be mindful of the travel schedule. And I do say that to my own patients, because there is a residual within the pump, but you do not want the pump to run dry. So it’s very important to you know, mention any travel to your your treating physician and to try to accommodate that for patients as well. And otherwise, what I also want to highlight, and I mentioned this a little bit with the consortium, but there’s been a huge increase in terms of the number of centers since 2019, that are able to put in a level upon number one, and also for local refill centers. And this is something that is continuing to gain momentum. I think this is something that I learned, I’ll be honest with you during the COVID pandemic was so important for patients because there was huge difficulty in in people being able to commit to coming here every two weeks to New York at for pump refills and, and there’s a lot more physicians out there, and who who can now help assist with local refills. And that can be huge for patients, even if they’re not able to get the flux your dean locally, for example. But coming to coming to New York once a month is much better than having to commit to traveling every two weeks for example. And, and you know, it is important to also to mention that and we are trying to help train local oncologists also who maybe don’t have experience with the pump, but to be able to help some of some of you and some new patients who really want to commit to this to have refills locally. And then just to briefly mention, you know, some of the safety elements with fluoxetine. So, the anterior pump is indicated for the use of fluoxetine and it is contraindicated to the use of this and patients who have extensive extrahepatic disease or if you have limited liver function. And then always important to mention, you know some of the adverse events that can occur with the pump which are rare but serious and we can discuss them a little bit further in the q&a section.

Dr. Connell 19:59
So with that, I’m going to hand it over to Betsy, and we’ll go through the questions. So I’ll stop sharing here.

Betsy Post 20:08
Great, thank you so much. And then please, as we go along, if you do have questions, actually, I have one, two for the end, please do put those in the chat and we will get to those shortly. So the first question we have Dr. Connell is Why is HAI therapy generally done at the same time as systemic chemotherapy?

Dr. Connell 20:31
Yeah, so, you know, this question comes up a lot. And I think the important thing here is the there is a synergy between fluoxetine through the pump and giving it with systemic treatment in particular arena Tekin, and our EGFR inhibitors, but also importantly, we have to protect against the risk of extra hepatic disease, right. So if I have a patient and they’re on track to try to get to a liver resection, what is absolutely devastating for a patient is to get to a surgery. And the procedure is aborted because extra hepatic diseases detected and or for something to develop on a scan prior to surgery. So it’s really to help protect outside the liver, to allow us to focus on the treatment of the liver metastases with the flexibility and treatment.

Betsy Post 21:23
Thank you. How do you determine which systemic regimen that you’re going to use with the metastatic colorectal cancer liver met patients? And how does having a pump alter that?

Dr. Connell 21:35
Yeah, and so the first thing to say is that, while we typically and in the majority of patients give systemic chemotherapy with the HAI therapy, the dosing is automatically lower than it would be if a patient was receiving systemic chemotherapy alone. Because we have to balance the toxicities from using the two in combination. And so there is a different standard dosing of this systemic FOLFOX, for example, as opposed to somebody who’s on FOLFOX own in terms of what to use for patients. So there’s a few things to look at. I think the first thing is, in a patient who is previously untreated, the standard would be to use Folfox.

Dr. Connell 22:19
With the liver pump, and in somebody who possibly comes and they’ve had both treatments, what I take into consideration is I look and see, you know, what response, did the patient get to each individual systemic treatments previously, right? Did their cancer previously progress on Folfox? Do they maybe have stable disease on full theory, but they didn’t get enough of a response, and also the side effects that patients have had from previous treatment. So if somebody comes into me in clinic, and they have very severe neuropathy from previous oxaliplatin, I’m not going to jump to using that drug. So I think what’s important to consider is how the patient’s cancer has responded to previous drugs before the time interval that they’ve had from a particular regimen to perhaps another recurrence or something else developing and also the side effects for the patients from previous treatment.

Betsy Post 23:13
Thank you. The next question is, are there any situations where the HAI therapy might be done without systemic chemotherapy at the same time,

Dr. Connell 23:27
Um, very, very rarely, I have one patient since I began practicing here that I’ve done it in so I very, very select patients. In general, the preference is to give with systemic chemotherapy. Again, you know, in, in the scenario where I decided not to do it, it was a very detailed discussion with the patient about why we were not doing it and the risks of of not doing it together. But in general, it’s given. It’s given with some form of systemic chemo. And, you know, what I prefer for my patients is at least we give a single agent even if a doublet such as you know, 5FU with oxaliplatin or 5FU with Ironotecan is too much. And but as I said, it’s very rare that I do it. I’ve only done it once since I’ve been practicing here and had very real reasons for not doing systemic side effects may be possible in the liver area during HAI therapy.

Dr. Connell 24:28
Yeah, so the side effect profile is very different to systemic chemo. The two main things that I say to patients is we learned early on and many of the studies that were done with the liver pump the the risk of ulceration in the gut in the GI tract, so all patients are put on a medication to help prevent reflux. So pantoprazole protonix, and in patients who say to me that they’re having increasing reflux symptoms, for example, or they’re having some pain or discomfort, you know, just under the chest, and I’d have a very low threat To get an endoscopy to look for an ulcer, so that’s the first thing. But it’s much less common nowadays because we’re routinely giving protonix with it. I think what the big thing is, you’ve got to watch the delivery of blood work very closely. And in the majority of patients, you don’t come to clinic with any symptoms, right? You feel fine, you feel well, in general, patients feel better than they felt on previous systemic chemotherapy because okay, I’m still giving it but I’m giving a little bit less than you would have had previously. And what I always say to people, actually, when they come to me is it can be a little bit frustrating, right? If you fly to me from San Francisco, or you come from Canada, and you feel great, and then I see the liver enzymes, and I say, sorry, I can’t give the drug today or you know, we’ve had to give a few weeks holding off on the drugs. So the honest answer is we’ve learned from experience that we do have to be very mindful of the liver bloodwork, and then the majority of patients picked up on the bloodwork and the patient doesn’t have any symptoms themselves. However, in some patients, if you begin to develop any symptoms, such as jaundice, you know, anything like that, then a very low threshold to get your liver enzymes checked. And even if you’re local, to check them to see because that’s the biggest thing that we have to watch for is liver toxicity.

Betsy Post 26:16
How long does active treatment last? And what is the average number of treatments? And does this change? Does this change if the HAI therapy is being done before or after liver resection?

Dr. Connell 26:30
Yeah, yes. So the answer to the final question is yes. So if somebody has had a liver resection, and we’re using this as an adjuvant treatment, it’s six months of treatment. And then we stop. And in the majority of patients, we’ll get four doses in of the fluoxetine of the liver drug in the six month period, when we look at, you know, liver enzyme alterations, but we stop automatically at six months, and however many doses the patient has managed to successfully get that’s it. And in a in a person who is not resected, or I’m trying to convert to resections, when unresectable disease or in the conversion setting, there really isn’t a limit in terms of the number of doses that a patient can get. And the it really depends on how their liver is tolerating the drug, you know, what kind of response that we’re getting, you will have to make a change to the to the drug dosing. And what I’ve seen in practice is that typically, that happens around two to three months into treatment. It’s not uncommon, that it could happen even after the first dose, but there will be some dose modification. And patients can still respond on low doses. And that’s also important to say, because again, I also acknowledge that, you know, really, you’re committing to come in here for these treatments or to hai center. And it’s very disappointing, if you hear you’re getting a quite a significant dose reduction. And but you still respond to this. And it’s different to what we know about the dose reductions that are done with systemic chemo.

Betsy Post 28:04
Thank you. Is it possible to do treatment again, with the pump later on, if needed? 

Dr. Connell 28:14
Yes, exactly. Yes, you can. And this is why, you know, our, our preference is for patients to keep the pump, right, because particularly, what I would say to patients is, if you are using it as adjuvant therapy after liver resection, or you’ve been converted to resection from the pump, at the time of surgery, the recommendation, so your NED at that point, right is at least two years. Ideally, we prefer patients to keep the pump in longer. But the highest risk period for recurrence is the first two years and the rationale behind that is because the pump is not something that can be put back in right a little bit like a metal porch, right? So we want to keep that option open. Particularly if, if it’s helped you get to your surgery, number one, and you know, so that we can use it again. So absolutely, yes, you can use the drug again.

Betsy Post 29:11
Thank you already answered the next one, which was does the pump stay in when active treatment is done? And for how long?

Dr. Connell 29:18
Yes. Yeah. Yeah. And so yeah, and this question comes up and the honest answer is as well what I would say is i i Never tell someone to take a pump out I wait for them to tell me that they’re ready for it to come out because I think it’s a very personal decision. I think it’s something that for many patients has been you know, revolutionary, I guess and and I think, you know, we can educate and guys and that but it has to feel right to you as a patient to know when is the right time to remove it. If somebody really wants it out within six months. I’m like, please keep it for two years but beyond that, I really leave it up to the patient’s decide

Betsy Post 29:59
Are there other drugs ever used in the pump like oxaliplatin?

Dr. Connell 30:05
Yeah, so, oxaliplatin has a very low extraction rate into the liver. It is used in Europe because they have a slightly different device there. We don’t routinely use it here. But we do use Mitomycin and that’s something I referred to briefly during my talk. And I have seen patients who perhaps are beginning to develop some resistance to Flox your deen or maybe are beginning to run into more issues with their liver enzymes. And I’ve used Mitomycin in those patients and seen you know, some very good responses with the middle myosin what I would just say about that is you can give it in combination with fluoxetine. So you can give both drugs at the same time if your liver enzymes are good. So if the liver bloodwork is good, if the liver enzymes are high, tickling the outsource or perhaps the bilirubin, and that it’s safer to give Mitomycin on its own, but that’s typically our second drug that we use. We don’t give oxaliplatin.

Betsy Post 31:09
What are the causes for the mitomycin following HAI therapy with the traditional treatment?

Dr. Connell 31:19
Why would we give it right?

Betsy Post 31:21
I think you already spoke to that. 

Dr. Connell 31:24
So yeah, yeah. So I think if you’re getting a slowing down in response, possibly to flux, your routine, maybe you are getting some response, but you’re beginning to run into some of these liver toxicity issues. And so they would really be the main reasons that we do it. And really, I would use it in a situation where it’s liver only progression, of course, like I wouldn’t use it if there was signs of anything happening

Betsy Post 31:47
Um, and then since I’m not an oncologist, I might mess up these names. But what are the views on the use of Bev, which I know is Avastin. So we’ll take that one first. The new third line or a drug that was just FDA approved for colorectal cancer, liver Mets, or the EGFR inhibitors. So what are the views on those three and maybe address them separately? Because I know it could be different after the HAI therapy when the pump is running glycerin.

Dr. Connell 32:18
Okay, so I’ll start with EGFR inhibitors first, because that’s probably the easiest ones you can give EGFR inhibitor is at the same time that you give fluorouracil safe to do works very well with the liver pump.

Dr. Connell 32:32
And you can also give it after liver treatments. So there’s no limitation at all with EGFR inhibitors and actually works very well with with FUDR, or Avastin is something that we’d urge early on, that should not be used the same time that we’re giving fluoxetine. So it’s it’s a combination, so it should not they should not be used together. And but a patient can have Avastin or Bevacizumab later on, if you’re simply just getting glycerol through your pump. And so, if for example, I have somebody who the liver is still no evidence of disease, there’s, you know, issues arising outside the liver in the lung, perhaps or lymphnodes. Have I given Avastin? Absolutely I have, I generally prefer to try to delay the use of Avastin further out from using the liver drug because I have seen in some patients some delayed issues with billary complications if I’ve tried to use the Bevacizumab a little bit too quickly after stopping the liver pump treatment. And but yes, you can use them separately but not together and then forget never the honest answer is we don’t know yet. Because it’s such a new drug definitely would not use them together. And I think you know, you would think along the same lines as you know, what we do with Stivarga, etc. You know, they can be given but not together. And the honest answer is and I kind of led to this during my sliders, I really reserved the use of any of these drugs too much, much later on for patients. I think if you can do something like long ablations or radiate, I think you’re helping the patient more than jumping to any of these newer, third fourth line drugs that are approved.

Betsy Post 34:17
Thank you. And these are questions that we see in Colin town all the time, and these were the most frequent questions that I received for you. So these have to do with Y90 So if a patient has had Y90 How does this affect their ability to receive HAI therapy after?

Dr. Connell 34:38
Yeah, okay. So this comes up quite a lot. The honest answer is if I see a patient before a Y90 Maybe they come with a second opinion we usually prefer to give the pump before Y90 that’s the honest answer. So usually what I say to patients is, you know, pump first and any of these proceed procedures like Y90 or radiation I would reserve for later on. And have I had patients who’ve had y90 And I’ve given pump treatment to absolutely, I think we have to look at those cases individually. And it’s something that we would show at our tumor board. And we would really look at the extent of the Y90, for example, how the blood vessels in the liver look after the Y90.

Dr. Connell 35:24
Often you need to dose reduce the flux your routine a little bit faster in those patients so I can get the drug in for the patient, but I can’t get as much drug in. And but I’ve had people respond after y 90 I think our preference is to do pump first.

Betsy Post 35:45
If a patient has HAI therapy, and then does Y90? Would the patient be able to use the HAI pump again, if it is still functional?

Dr. Connell 35:56
Yeah, and so this is an interesting one. I haven’t personally ever done that myself. I think from a technical point of view, it would come back to what I said previously, is that you’d have to really look structurally at the liver and see, you know, there’s there’s newer Y-90 techniques out there. And I know whether our interventional radiologists here they do more selective Y90 So if perhaps, you know, there was a regional Y90 And then you’re trying to treat the rest of the liver. Technically, you could. I think just with with my own practice, and the way that I view it, because I keep Y90 for Later on, it just hasn’t worked out that way with the patients that I’ve seen. But again, I think this is something that you would have to have the right imaging, it would have to be viewed as a multidisciplinary team, whether that’s the right thing for the patient, you know, including an interventional radiologist, including a radiation oncologist right, is radiation safer than Y90 A surgeon and a medical oncologist to decide what’s the right thing for that particular person.

Betsy Post 36:56
Some additional questions have to do with transplants. This is something that we’re hearing more and more about, especially for unresectable disease, obviously, and we have patients a lot of times that are making a decision, sometimes between the pump or transplant, but something that we’re hearing now is the question first, could the pump be used as a bridge to liver transplant?

Dr. Connell 37:18
Yeah, so this is very typical? I think without intentionally setting out that way. And I’ve had some patients who’ve done very well with transplantation after pump treatment, I think the tricky thing about the transplant process is that it’s a long process for patients. Right. So my own experience with my patients has been is that sometimes they’re waiting like 12 to 18 months. And I’m trying to control everything with the pump at the same time. So I have used it but not intentionally. I’m on discussions with transplant centers. And speaking with surgeons here, this is something that I think we’re going to need to study. And we’re going to need to collaborate on to see if we can help more patients by combining the two techniques.

Betsy Post 38:37
Another question, how do you consider the option for liver transplant as part of your overall treatment plan or approach for patients?

Dr. Connell 38:47
Yeah, so. So when I see patients, you know, this can often come up. And I think with transplant, what I say to people is we got a real sense of how the pump is helping a patient in unresectable disease, like, you know, about six months in, you know, look, and you’re talking back and forth with the surgeons, you know, do we think that we’re going to be able to convert to resection here? Do we have any of these options like why nine tear or radiation? And I think it’s always appropriate to get an opinion from a transplant center, and particularly if it’s something that the patient themselves is questioning, right, because you want to hear directly. And there’s a little bit of bias right between different different specialties and obviously I’m very Hai and but I’ve certainly collaborated with transplant centers, and then you know, when somebody is listed for transplant in practice, what I do is I follow what they want me to do, so I don’t change any treatment, you know, they tell me what they want to do. The important things about transplant is a few things. So you cannot have any extra hepatic disease obviously so there can be no evidence of extra hepatic disease. And the second thing is that the primary tumor has to be removed.

Dr. Connell 40:03
So, you know, they would be the two things. But if you have liver only disease and and resection is not feasible, and you’ve heard that from the liver surgeon and you’ve heard that from your medical oncologist then then I do think transplant is something that needs to be considered. And they removed the pump at the time of transplant as well. 

Betsy Post 40:26
So is there data available to show how successful ATI therapy is? And I know that we did talk? You talked about that earlier, but I didn’t know if you wanted to elaborate on that a little bit more.

Dr. Connell 40:39
Yeah, so we do have data. And I’ve shown some of the data here, I think what’s important is that we need more randomized to data. And I think, you know, that’s what the consortium is going to help with and why we’re trying to collaborate with other institutions. And I think trying to address this question of, is the pump so successful? Because it’s given here in New York or you know, Kansas, can I get the same level of care? Or in Chicago, or, you know, Atlanta? And I think the honest answer is there’s so much more knowledge out there about the pump. And we do need to do more trials. And also, I also mentioned this as well, there’s so many newer drugs out there, right. And patients want to know can kind of get them together, is it safe to get them together? And this has to be done in a trial setting.

Betsy Post 41:27
So another question we get quite a bit. So now that Dr. Kemeny has retired, how was care being distributed for patients that are being seen at Memorial Sloan Kettering?

Dr. Connell 41:39
Yeah. And so what I would say about that is, honestly, all of us can can can do pump treatment, I think a huge part of Dr. Kennedy’s legacy. What’s visible to patients and caregivers is is what she did for you, right? Understandably, a huge part of her legacy for us at Memorial is the teaching and training that she gave to us. And, you know, she was a phenomenal mentor to me. And to many of my colleagues.

Dr. Connell 42:10
All of our practices differ a little bit. So some of us do more pump than others. But honestly, all of us can do pump in terms of her practice. And it’s been divided between Athol I think for for active patients, understandably, because I was mentored under her I have many of her patients. I think, what’s also important to say, though, is that, for any of you who have, you know, some complex decision making, there’s something to be to be, you know, figured out, you know, is it now the right time to think about y 90, you know, have I achieved what I can with the pump, that’s never a decision that’s made in isolation by an individual, whether that’s a medical oncologist, it’s our tumor board is a huge resource for people and, and that’s often what I what I see myself as like, You’re not coming here to memorial for me, you’re coming for the expertise from the whole group. And never think that a decision a very important decision like that, look, will I say to this patient that you should go and get a transplant opinion, you’re not going to hear that just for me, I’m going to speak with my surgeons I’m going to speak with with them, and we’re going to show your case at the tumor board. And I think that’s very important to know, is that there’s huge collaboration amongst us as medical oncologists, and also multidisciplinary team involvement in any major decisions for patients.

Betsy Post 43:31
I know that you spoke about the Consortium, and that all the pomp programs, especially since my team that have opened up, but How can patients across the country get good access to HAI therapy?

Dr. Connell 43:44
Yeah, so I think there are more centers, who are implanting the pumps, number one, and also so many more centers where, you know, they’re able to assist with with local fields, I think the consortium is really helping with that. I would also say that there’s a huge collaboration between us, you know, I definitely speak with medical oncologists at other institutions. You know, I relied on mentoring, when I started off with this, and I try to share what I’ve learned in the nuances, you know, with oncologist with other centers, I think, when you start off, you know, what I always say to people is, you have to be comfortable with the person that’s treating you, right. And whether that’s having a pump or not having a pump, I think, number one, you have to be comfortable. So, you know, and you also have to think from a practical point of view, you know, look, if financially and with my family or my work commitments, is it feasible for me to fly up and down to New York every two weeks? And for many patients, it is for others. It’s not. Do I have a local doctor who can do this? Did I did We did our personality match? You know, and but I think there is so much more knowledge out there nowadays and there’s also huge camaraderie between us and sharing of knowledge. And, I think the consortium and the trials and everything that’s going to come out of that is going to further reinforce that for patients.

Betsy Post 45:11
One more question, and then we’re going to take the live questions, we have quite a few. How does the start of that new pump trial impact the ability of new patients to receive HAI therapy?

Dr. Connell 45:23
Yeah, so it’s a very relevant question. And you know, what I would say about the pump trial, it’s a very, very select group of patients, right? It’s a very important study, right to help answer this question, in a randomized setting of, you know, conversion to resection for patients with HAI versus modern systemic chemotherapy. So it’s for patients who’ve had more than three months, but less than six months of systemic chemotherapy in the first line. So it’s a very small group of patients. And the honest answer is the reason that we’re doing that is because we don’t know the question, right, we are the answer, we wouldn’t be doing it if we already knew that one was better than the other. And that’s important to say about any trial. If you’re a patient who is untreated, you had no chemotherapy, you can have a pump off trial, if you’ve had more chemotherapy, like you’ve had a year of chemotherapy, you don’t, you don’t qualify for the trial. So it’s a very, very select group of patients. And that will be explained to you as well, in the in the in the clinic setting.

Betsy Post 46:30
So moving on to some of our live questions, we have one, is there a certain temperature that you have to keep your body under while you have a pump?

Dr. Connell 46:42
Yeah, so this question comes up quite a bit, you know, I think you have to be sensible, right? So he will speed up the rate of infusion of the drug. Hot tubs are a no, no, you can get in a swimming pool. And so body temperature can affect us, I don’t give anyone like a specific number. But I just say like, you have to be mindful of it. And I have a patient who said they have a hot tub with that, put it on regular temperature. So you know, swimming, and all of that is fine. But sitting in heat, you don’t want to put heat pads directly on the pump. If you have pain in your back for another reason, you can put heat out there, but you just want to do want to put it directly over the pump.

Betsy Post 47:25
Is it true that you can’t lift more than 10 pounds when the pump isn’t?

Dr. Connell 47:31
Yeah, so again, this comes up quite a bit. So usually I say around 15 pounds to patients. In the beginning, I think you have to be very mindful of that similar with any surgery to be honest with you. Over time, honestly, what happens is you have a very good sense of your pomp and also scar tissue forms. And so I tell patients that, you know, using a binder, you know, be sensible. But a lot of people say, Well, you know, my toddler is 30 pounds, you know, and I’m never gonna say to somebody, you can’t lift your child up, you know. So I think within reason, and I think if you’re, you know, the further out, you get the sense you have your palm, the binder, scar tissue, and, and, you know, for lifting children in the beginning, I usually say to people, you know, sit down and lift them up onto your knee, you know, things like that. So I try to be creative with how you do things. But I do think we have to be practical in that regard. And the concern about the weight lifting is the connection between the catheter and the pump, and also the risk of, you know, the pump flipping, and the more secure it is over time that the lower the risk of that

Betsy Post 48:39
Um, there’s a question about the drug and mutations. And I know specifically, we do have some BRAF patients here. So question, there’s a question about, is the HAI therapy equally effective for all mutations?

Dr. Connell 48:56
Yeah, so it’s a very good question. I think what I would say to you is, is that we do use the pump and in all patients, I certainly have myself patients who have BRAF mutations, and I’ve used the pump, and I’ve seen some very good results with it. So I wouldn’t discriminate based on that. And but I think it’s something that we’re going to need to study a little bit further to see how we best serve people going forward. But I definitely have patients who’ve done well. And you know, maybe later on I’ve used the combination I mentioned earlier, such as graphics to toxic map, and but if they have liver only disease, we still put pumps and we still get flux your routine and I’ve definitely seen good responses. I have a patient who was probably an outlier but from from early 2019, and still NED

Dr. Connell 49:47
and had, you know, resection, had liver pump to get your resection and as BRAF mutated, you know,

Betsy Post 49:55
right. I think you answered this, but I’ll ask it for those pursuing liver resection, is there a recommended number of fudr treatments from the pump before considering surgery?

Dr. Connell 50:10
And so the honest answer is there isn’t a set number per se, if somebody has unresectable disease. So what we do is we scan every two months because we want to keep a close eye on the response that we’re getting and how the liver is tolerating it, right? So you’re scanned every

Dr. Connell 50:29
which is a little bit different to the adjuvant in the adjuvant setting, you’re scanned every three. But what I usually say to people is that honestly, at two months, it’s it’s not very common that patients are ready for surgery, it’s typically around the four to six month mark, but there isn’t a set number is really depends on the location of tumors, the technicality if somebody has liver, you know, bi lobe disease, so both the right and the left side involves the surgeon will say to me, Look, we need to do these portal vein embolization, you know, certain procedures to help get to a second stage liver surgery. So the some of those factors to come in. But there’s no hard and fast rule with the number of doses that a patient has to have

Betsy Post 51:13
HAI pump decisions require very close coordination between the medical oncologists and surgical oncologist Are there any best practices from that cross specialty communication that you would highlight is beneficial to apply? Even beyond the HEI application?

Dr. Connell 51:31
Yeah, so, you know, what we’ve learned to serve patients best is that multidisciplinary involvement is so so important. Right? And, and I kind of, you know, said that earlier on, like, any major decision point you need to think about, you know, how am I helping the patient right now? And also, how is this going to affect what I want to do in the future for the patient? Right. So in my own practice, here, I do my clinics alongside the surgeons at for that reason. And you know, when I asked some of these questions, we also have very heavy input from our interventional radiologists. And I think that’s very important is to try to get the different options there. And sometimes there is there’s two options, right maybe let’s say for the liver, it could be resection or it could be ablation, and then we can see both and help make the decisions by getting the input from from both specialties for example.

Betsy Post 52:32
Are there restrictions on jogging and working out?

Dr. Connell 52:37
Okay, so what I would say about that is if you put 20 of us in a room, a mix of surgeons and medical oncologists, everybody would say something different and it’s very controversial. And I allow my patients to light jog and the the concern again is really the connection of the catheter to the pump. And again, what I say to people is exactly what I said weightlifting you know, if someone comes in to me and you know jogging is your is your your cam time, you know, your therapy so to speak. You know, it’s very hard to say to somebody, you know, don’t jog and but I say you know, try to be sensible about it, have a binder on Wait a while and I do allow patients to do like jogging. The surgeons do lap people jog and there’s other medical oncologists who say no, and we love stationary bike. We love the peloton. That’s, that’s probably the safest thing that you can do and the best thing and a good form of workout. But yes, I do say to patients, they can jog.

Betsy Post 53:41
So if there is a patient that has, for example, ovarian or peritoneal disease, but the patient was potentially able to have all of that removed. Could they still get pumped?

Dr. Connell 53:56
Um, so for over a yes. So if you have liver and ovary because we know that colorectal metastases to the ovary, are quite resistant to chemotherapy, so in general, the bias is to lean towards surgery in that situation anyway. So you would often do if you can do a liver and you would also remove the ovaries at the same time. So yes, with peritoneal disease, there’s a little bit of pause. I’ll be honest with you. The tricky thing about peritoneal disease is that you often can’t fully appreciate peritoneal disease on scans. And and it’s only at the time of surgery that you really have an understanding. And I’ve had some patients where perhaps there’s been like limited peritoneal disease, you know, a year ago it was removed and maybe they come looking for a pump. And and usually if there’s, you know, a period of time, typically a year, year and a half, not thing happening in the parish name again, then, you know in select cases we’ve put pumps in. And but I wouldn’t say to you upfront that I’ve put a pump in for a patient when they have active peritoneal disease at the same time.

Betsy Post 55:14
For every two to three months scans, do you do CT MRI, and I’m gonna throw in there you PET scan stew? Might as well add it in.

Dr. Connell 55:24
Yeah, and, okay. Um, so in that regard, what I would say to you is I started off using CT and patients. So I do routinely, CT chest, abdomen and pelvis. Over time. From looking at the CT scan, you understand with the individual patient, whether you’re seeing things clearly in the liver or not, if not, particularly in patients who maybe have, you know, a lot of chemotherapy prior to the pump being placed, because the chemotherapy changes the texture of the liver, what we call like fatty liver change, or sclerosis. So in those patients in MRI may give additional information. So the honest answer is, my starting off rule is CT only, I’ll involve an M or liver if I feel like I’m not seeing things clearly with a CT. And I really don’t routinely use a PET scan, unless I get to a point in a patient where a specific question has come up on a on a CT, for example, I do a patch, and I see that the patch is giving more information than the CT has. Similarly, if I do a patch on a patient, and I see that I’m not getting anything different from it, then I don’t routinely follow with Pat. And I think that would be the standard approach. For most patients. The tricky thing with PET scans is there can often be you know, false positive things on a PET scans and something lights up. And it’s it’s not anything related to the cancer and then it causes, you know, a lot of concern, understandably. Yeah, so that’s how I would view it. But I do have some patients where I know that only MRI shows that are only pet shows that and then once I learned that with the patient, then I continue to use that imaging modality. But I still always do my CT as well.

Betsy Post 57:12
We have one more question about I think exercise I see here. What about horseback riding? I’m a serious equestrian.

Dr. Connell 57:21
Yeah, so this came up for me recently. The issue with with horse riding is the bouncing activity. Right and the concern for the catheter? Again, I don’t think it’s a complete contraindication I think, and I know I’m repeating myself a lot but wearing the binder, a similar lead to what I’m seeing with light jogging. I mean, you can I don’t even know the word for isn’t trotting. for horse riding, you know, you have to be mindful of that. And but I wouldn’t, you know, I wouldn’t say you can’t do it again, if that’s something that a patient is passionate about, and it’s their form of relief, or escape from what’s going on, then I think that’s important to consider. So have a binder be mindful. That’s what I would say.

Betsy Post 58:07
We just have two or three more. So how would you know if there’s a problem with the connection from the pump? Perhaps from over lifting, etc?

Dr. Connell 58:19
Yeah, the honest answer with that is that most patients don’t know. And it’s picked up on scans. That’s the most common scenario. And that’s really where we see it. If somebody has, you knows, for example, they’ve had a trauma, you know, so So I had a patient a few years ago, and they were in there on a regular bicycle, and they flipped over the handlebars, and they were like, This doesn’t feel right, you know, so I scanned and you know, there you knew there was some incident proceeding, and you would check for it or they had pain afterwards. But the honest answer is in the majority of patients picked up on scans and you don’t feel any difference.

Betsy Post 59:03
Let’s see, I know I’m gonna mess this this word up.

Dr. Connell 59:08
So what are the thoughts around using the capecitabine with the pump while receiving radiation to treat the primary replacing traditional systemic treatment? Okay, yeah, so this comes up quite a bit. So when patients have a rectal tumor and you know, you can treat them with chemo radiation. So we do, you know, and you know, that’s in terms of a rectal tumor, the surgery is much more life altering. So if you can effectively get a complete clinical response or fully treat the rectal tumor than chemo radiation is recommended. What do I do in my patients? So the issue with Capacetibine Xeloda is that it causes more increase in liver enzymes, and it can affect the dosing of the fudr. So what I do for patients is if

Dr. Connell 1:00:00

We have a rectal primary and we’re doing chemo radiation. And we’ve just put a pump in for liver disease, you can give the fudr you can give the liver treatment during the chemo radiation. But instead of using the Xeloda and or capecitabine of being I use fluorouracil which is sort of the old way that they that they used to do chemo radiation. And because again, I want to try to maintain the higher doses in the pump and keeps it being tends to interfere with that more. So.

Betsy Post 1:00:36
I think I got to almost every question, one of my questions that I have, if I can just sneak one in I know it’s 802. But with all the centers opening up, I feel like we’re seeing some oncologists are using the Urso dial and some are not. And I don’t know if you feel comfortable speaking to that, and how you use it in your practice and how the decisions made to use that or not?

Dr. Connell 1:00:59
Yeah, it’s a very good question. I mean, I think what I would say to you as well is there’s even differences in the practice here at Memorial as well. I, I use it quite early on in patients, because I think, you know, the two ways we manage the liver inflammation are the steroids through the pump at the time of the flush as well as versatile. And, and in the long term for patients being on steroids continuously. You know, there’s this kind of late side effects with that there’s the weight gain that comes from steroids, there’s a few patients where versatile can be a little bit tricky. So sometimes patients can notice the very loose stool. So if I have a patient who’s struggling with, you know, diarrhea issues or anything like that, from arena Tekin, or even five floor yourself, I kind of hold off on the earth a dial, but I tell them why I’m not doing it, you know, but I do tend to use it early on. And I also tend to keep it on board longer, even after I’ve weaned down the steroids in the pump, and I have someone off treatment, because I think it helps with the liver inflammation, I typically start off on twice a day in some patients, you may have to go up to three times a day. But again, if you even select 10 oncologists here at Memorial, everyone would do something a little bit different. But I give the options to patients. And I also explain, as I said, when I don’t use it and what my concerns are for that particular person.

Betsy Post 1:02:31
Well, it’s 8:04. And I think we have gotten to most of the questions. There is one here that I’m not sure we may have to get back to because it’s you know, the top centers for ATI. And with so many new centers that have opened up since 2019. I think by volume, we’d have to kind of look into that to see who they are. I know Duke is one of them. I know they’re very, they’re a high volume center now. But with the opening of the consortium, I know we have a lot more centers throughout the US. So I can take that offline. And definitely I can talk to the folks at inteiro on that as well. Just about the volume at the other centers. But yeah, so I just wanted to say again, thank you so much for your time, I learned a lot. And it was so good to hear just from a medical oncologist. So in addition to Dr. Kemeny and hear how you’re using it, your practice, and I learned a lot of just about the trial and other things. And your take on that. And I really appreciate it. I know you were so generous with your time and answering all of these questions for the patients. And we really all appreciate it. So thank you so much. And I know we’ll be in touch if we have additional questions. So thanks for everybody that attended tonight and thanks for all your participation. We really appreciate it. So have a great evening. Thanks again. And we’ll see you soon.

Dr. Connell 1:03:46

In this DocTalk, Dr. Sekhar Padmanabhan from Vanderbilt University discusses optimal management of colorectal liver mets and HAI. Recorded in May, 2024.

Betsy Post 0:05
So welcome everyone to tonight’s DocTalk. Thank you so much for being here to watch this live, and then for those of you that will be watching the playback, thanks so much for your time. I am so excited to bring Dr. Padmanabhan here to talk to us about the optimal management of colorectal liver metastases, the perspectives from a liver surgeon. Dr P has many fans in COLONTOWN, in the hepatic pump group, as well as in the main liver group, really passionate fans of his work and the life saving techniques that he uses at Vanderbilt. So it’s such an honor and a privilege to have him with us tonight. Thank you so much for being here. I’m going to turn it over to you in just a second, but just as a reminder for anyone that’s joined us live, please know that there have been some questions that were submitted in advance. So if you did have some questions that made the cut off to be submitted in advance they were submitted, and then he is going to do his presentation. And then any questions that you have along the way, please put those in the chat. So there’s a chat feature. Please use that to put your questions in the chat, and then at the end, we will save some time to go over the questions that come up throughout the presentation. So you’re all muted. Please put the questions in the chat if you have tech issues, Megan is here. She’s under COLONTOWN cabinet, and then I’m here under my name, Betsy post. So please just ping one of us if you have an issue. I’m going to turn it over to Dr P again. Thank you so much for being here. The floor is yours.

Dr. Padmanabhan 1:41
Great. Good evening, everybody. Thank you Betsy, Thank you Megan and thank you COLONTOWN for the opportunity to speak to you all tonight and to any of my patients who are logged in. Thanks for being here. I am eternally humbled that all of you have put your trust in me to sort of play whatever small role I have in your treatment. It’s truly, truly. To say that I’m humbled is an understatement, and I really appreciate you, know, you guys trusting me. So for those of you that I don’t know a little bit about me, so I’m a I call myself a hepatobiliary surgical oncologist. I practice at the Cancer Center at vanderwald Medical Center. And you know, for those of you that sort of don’t know how you become an HPB surgical oncologist, the path is not a short one. So after four years of undergrad and four years of medical school. I did my general surgery training here at Vanderbilt, and then I went to Memorial Sloan Kettering Cancer Center in New York City for two years, where I trained both in surgical oncology and hepatobiliary surgery. So that’s why I sort of call myself hepatobiliary surgical oncologist. I was fortunate to get recruited back to Nashville, and my family and I have been back here, and I’ve been on faculty for coming up on three years now this summer. So some of you might be wondering what this portrait is. So it’s actually a portrait painted by Peter Paul Ruben, 1618, it’s, it’s on display in the Philadelphia Museum of Art, and it’s actually entitled Prometheus Bound. So for those of you, I was a, I was a classics minor in college, and about the only thing that I remember from my time then is, you know, so Prometheus was a Titan, and he actually steals fire from Zeus and the gods and gifts it to mankind. Zeus, you know, as petty as the Greek gods were, was sort of enraged by this, and he chains Prometheus to the side of a mountain top and sets his golden eagle to sort of feast on his liver during the daytime and during the night time the liver regenerates. And so this sort of happens day in and day out. And it’s just interesting to me that the ancient Greeks, even at their time, had this concept of liver regeneration, you know. And basically, my field is dependent on hypertrophy of the liver after, you know, we remove portions of it. And so I just find this painting fascinating and and so I always have it as my, sort of my first slide, you know. Fast forward 2500 years from the Greeks, you know. And in 1931 a lot of the groundwork for sort of liver hypertrophy after resection was sort of done in early animal studies. And so I just sort of find this concept very fascinating. Real quickly. I don’t have anything to disclose. I have no financial incentives or commercial interests, though, my partners joke that they’re going to start to. Pay me to stop talking about this topic, since it’s all I seem to ever do. I don’t really claim to be an expert in anything. I am very passionate about this. For those of you who know me, this is sort of what I have devoted my life to, in the in the in the in the rest of this talk, I will try to differentiate fact from opinion, because I think that’s very important sometimes in in cancer care, cancer medicine, cancer surgery, a lot of people have a lot of opinions, and usually when there’s a lot of opinions, there’s not a lot of sort of definitive evidence or facts to base the opinion on. So I think it’s important to differentiate that, and I’ll try to do my best to do so. And lastly, I am not, you know, some none of these thoughts are original. Let me put it that way. I stand on the shoulders of giants. You know, I got trained at one of the best cancer centers, I think, in on this side of the Atlantic Ocean. And the faculty there, you know, train me to be who I am today. And you know, the faculty here at Vanderbilt also did the same. So I stand on their shoulders truly. So you can’t know where you got to go without knowing where you came from. So we’ll sort of talk about, you know, colorectal liver metastases really quickly, where, where treatment sort of was, where we are now. And then I’ll sort of talk about some, some future directions, and how we how we sort of plan to hopefully shape the field moving forward. I don’t need to tell this group, so I’ll sort of blitz through this stuff. But you know, we know, we all know that colorectal, colorectal cancer, is the second most common cause of cancer related mortality in this country. And I also don’t need to tell this group you know that it’s highest. Rate of incidence increasing is in younger and younger patients. And the liver is the most common side of metastatic disease, and 50 to 60% of people will develop liver metastases at some point, right? So, and we know that the metastatic disease is what drives the mortality with this, with this disease. And it’s interesting, if you go back to, you know, Memorial Hospital in New York City was called Memorial Hospital back then, in 1948 they were writing about this concept of the inoperability of cancer. George T pack was one of the preeminent surgeons in New York City at that time. And you know, he wrote this in this paper. You know, perhaps the strongest indication for hepatic resection occurs when a very long latent period intervenes between the treatment of the original cancer and the discovery hepatic metastases. And in some sense, that’s still sort of true today, although we are much more aggressive because we have much better treatments to do that. But this is, you know, back in 1948 you know, they were thinking about this problem. And you know, fast forward to the 1990s you know, you look at patients who, sort of, were diagnosed with colorectal liver metastases, this study had 1200 patients in it, and you can see that the patients who were unresectable, or were resectable, but didn’t get resected, did not live very long, and the people who did get resected live much longer, and many of them actually were cured of their disease. So if you look at at the line here, you know it’s about 20% 10 year survival, and this is in 1990 right liver surgery in 1990 or even before 1990 is not what it is today. A lot of it involved moving massive chunks of liver, you know. And the chemotherapy agents that we have today were not even existent or in use at that time. And so that’s pretty, pretty amazing, that that’s, that’s sort of what, what they were able to accomplish. You know, obviously, things have gotten a lot better since 1990 and you know what was a very, very high risk operation of dying just from the operation now is not so high risk. You know, you look at major academic centers like Vanderbilt, you know, Duke Memorial, Sloan Kettering, etc, the mortality after liver surgery is so much lower these days, and that’s why we’re able to sort of do what we do. And a lot of that is because of, you know, we’re able to prevent liver failure, you know. And we use specialized techniques. We were just talking about Alps before, you know, letting the group on, you know. So there’s all sorts of techniques out there that allow us to sort of preserve liver function after liver resection, and it really allows us to be much more aggressive than some of our predecessors were able to be. And you know, we’re able to assess the liver remnant. So you know, for my patients on the call, every time I tell you, I need to make sure that I remove all the tumors, but leave you enough liver behind to survive, right? That’s assessing the liver remnant. What am I going to leave behind, and how? And how am I going to make sure that it’s healthy enough, so that you live? And then, if it’s not healthy enough or big enough, then how do we grow it? Right? And those are the things that we’ve gotten better at. The other thing that we’ve gotten better. That is, you know, we’re better at surgery. And when I say we’re better at surgery, you know, we’ve realized that that less surgery can accomplish the same goal with similar results. And so you can see here, this is published by Peter King and one of my mentors from Memorial Sloan Kettering, that many of you may have heard speak in this forum at others, you know, you look at decade by decade from the 1990s onward, and you know, you can see that the number of major liver resections has gone down each decade, so less than almost a third. Now, if patients get get major liver resections, and you look at the mortality, and it’s gone down from five to 1% and that’s because, you know, you can get the same cancer outcome with removing less liver. And this was a study published at out of MD Anderson. And you know, I don’t want to delve into the weeds of all of this, but if you look at these curves, they’re essentially superimposed. And the two curves, the blue represents, you know, not removing a ton of liver, and the red curve represents removing a ton of liver. And so you can get the same result without removing, you know, massive amounts of liver. And that’s sort of how we’ve especially, I, you know, have continued to practice and trying to remove as little normal liver as possible, which I think is very important, and this is translated into much better outcomes. And you look at this study, also published by my good friend, who was at Duke, you know, so they looked at over 1200 patients who underwent initial liver resection for colorectal liver metastases, 34% estimated 10 year disease specific survival, so meaning 34% of people diagnosed with liver metastases were alive at 10 years. And that’s a that’s a big deal compared to where we were even 10, 15 years ago. And not only that, but people are living longer and people are having improved quality of life. And I don’t think we stress that enough in our surgical and medical communities about quality of life, because yes, you know, we can all sit here and high five where people are living longer, but we need to make sure, and we need to stress that the quality of life is improved, and I think that that’s really important. So who should get an operation in 2024, if you walk into my door, or if you walk into a, you know, any hepatobiliary surgical oncologist store, you know, who gets, who gets an operation? Right? This is a person you know who this is, you know, these are generic CT scans, but, but, you know, this is somebody with one tumor. And I think everybody sort of thinks, Okay, one tumor for sure, they should get get a liver resection. This is another patient that I’ve seen and treated before. You know, these are, you know, several more, but still, you know, very distinct tumors. This, in my opinion, is still, you know, somebody who should get an operation, you know? And then I think the ultimate thing is, this is a, this is a patient that I took care of when I was a fellow in New York, you know. But even this patient got several operations, you know. And I think that we really shouldn’t be thinking about, you know, tumor number, tumor size, you know, some of the things that we historically have looked at. But rather, we need to think about, how is the cancer behaving? How are we testing it? And, you know, figuring out who is going to benefit from an operation. So I think, you know, there are degrees of respectability. You know, there’s people whose disease are is resectable up front, there’s people who need to have two stage liver sections, and there are people who are not resectable, you know, up front, but we try to get them to resection. And, you know, I think each of those require a very, very trained eye, by, you know, a trained eye of a liver surgeon who understands the disease process, who understands the disease biology, and ultimately does whatever they can to get these patients to a liver resection, because we know they do better. So what do we do in the modern era, right? What do we do in 2024 right? So chemotherapy, for sure, plays a role, you know, and so does surgery. And I think that one of the issues you know, that we see on my side of the things you know, especially here in Nashville, is a lot of times, you know, patients coming from from rural areas or areas that don’t have, you know, specialized liver surgeons sort of available, sort of get put into this chemotherapy only pathway. And, you know, I am by no what means saying that chemotherapy should not be done. I think that it has a very, very important role, but I think that it’s really. Important, and you’ll hear me say this a lot. You know, getting the opinion of a liver surgeon early in the disease process, early in the diagnosis, is really, really important, because it helps, basically provide a roadmap for how the treatment is going to progress, with the ultimate goal of getting to an operation, you know, and then chemotherapy has a big role in that, but it shouldn’t be the only thing, in my opinion, and that, you know, just, and I use the word opinion there, because, in my opinion, all patients should try to get to a resection if possible, when they’re talking about liver metastases from from colon cancer or rectal cancer. We know that chemotherapy can be toxic, right? So those are, that’s when you have your when you have your meetings with the medical oncologist, and they’re checking your blood work every couple weeks. They’re looking for toxicity. They’re talking to you about toxicity, and they make their decision to, you know, hold doses, dose, reduce, etc, based off of those toxicities, you know, and I’m not going to belabor this point, but these are some of the things that happen. But if you notice, you know, all of these things result, all of these drugs, which are sort of the mainstays of the chemotherapy that we use, are directly toxic to the liver. So we have to be really careful with how much chemotherapy we give before we do liver surgery, because if you give too much, it really increases the risk of liver failure, and it really increases the risk of having a bad outcome after liver surgery. And we know that, you know, it’s associated with not only liver failure after liver resection, but also complication after liver resection. So that’s why it’s really important to involve a liver surgeon early, so that we only give as much chemo as needed before we can get to an operation, you know. And this is sort of hitting those points again, you know, the more chemotherapy people get before liver surgery, the higher the risk of complication and liver failure is, you know. And I’m not going to belabor the points on this slide you guys can read, but, but, but, you know, the more chemo you get, the riskier the operation is. And so again, trying to minimize how much chemotherapy you get before a liver operation is extremely, extremely important. And I put these on not that I know what any of these things look like under the microscope. I rely on my pathology colleagues for that, but, but really, this is what I see, right? So on the left, that’s a completely normal liver. On the right, you know, we’ll see blue livers like this because of all the chemotherapy that’s been given. And in the middle is sort of a fatty liver from chemotherapy. And those things can be really, really challenging to deal with in the operating room. Not, not deal breakers, not, not, you know, we can’t do this at all, but it definitely just increases the risk of a complication, you know. And my ultimate goal is to get you through your liver operation with minimal risk of complication. So when somebody comes into my clinic, I break it down by, you know, is this something that I can remove up front in one setting? Is it something that can be removed but may need two settings, or is it something that can’t be removed and I need to get some response so that I can get to an operation, right? So initially resectable disease, meaning I can remove it up front. Okay? This is a really busy slide. All I want you to focus on is, is that when we tested whether chemotherapy should be given after removing liver tumors or liver metastases from colorectal cancer. None of the studies that we have shown have ever demonstrated sort of a five year overall survival benefit. Okay, it’s a mind blowing concept that often gets glossed over, but when you have tumors in the liver that can be removed. Giving chemotherapy after, systemic chemotherapy after removing the liver has never been shown to provide a survival benefit. It’s mind blowing, you know? And then you even go to chemotherapy before and after. So some people are like, okay, maybe it doesn’t work after, but maybe it will work if we give some before and some after. And again, this is for tumors that are removable up front, even then, you can see that the five year survival benefit is not there and it’s mind blowing. And we don’t truly understand in the cancer world why that is, but we have to be really, really selective of who gets chemo upfront, because it seems like it may not be helping, and so I usually reserve, you know, chemotherapy for detectable disease, for patients whose tumors are big, and if we can get a little bit of response. It’s we can do less liver surgery. Right? In my mind, I want to take out as little normal liver as possible. And if I can get a little bit of shrinkage here, getting the tumor to move away from this blood vessel here, or this bile duct there, and I think that if I get that couple millimeters, it will spare, you know, a bigger liver resection, and we can do a smaller liver resection, then I think it makes sense. But again, I have to in the back of my mind, I always have to think about the fact that, right, we’re not improving survival with this, and we are definitely increasing the risk of complication. So again, we try to do some chemotherapy if we have to. I love to do it without it if we don’t need it, but if we have to, trying to do just enough to get response without causing too much toxicity in the liver. I’m a big, I’m a big the office fan. And oftentimes when I think about, you know, chemotherapy and colorectal liver metastases and all the data out there, none of it ever seems to make any sense. You know, like, in your mind, it’s like, well, chemotherapy should work for this. I don’t understand why it doesn’t, and I think it I think it does work. I’m not saying it doesn’t work. I think it does work, but I think we have to be really, really selective in who we use it in for people that have disease that’s resectable up front, people like this, where you know the tumors are so widespread you can’t remove anything up front. I mean, obviously I think chemotherapy up first. Here is the right answer. Okay, we need to get these things under control. We need to get them to start responding. We need to get them to shrink. We need to make sure that, you know, the disease is not sort of growing gangbusters. And we lose, we lose control, you know. And so in the last decade, you know, 2014 to 2020, or so, we studied this to figure out what chemotherapy, you know, we should do, and we should use, you know, and so, you know, most of you are probably familiar with FOLOFOX Avastin FOLOXIRI plus Avastin, FOLFIRI plus Avastin, and that’s typically what we use based off of this, excuse me, this first study here, the tribe study, right? That’s pretty much first line for anybody who comes in, unresectable. Upfront, colorectal liver metastases. Now, there are unique scenarios where we may use, you know, full Fox plus panitumumab or an EGFR inhibitor. Those are very unique. Most people were talking about full Fox hearing Avastin, okay? And it’s a really, really good regimen, okay? And if you’re able to be healthy enough and strong enough and well enough to get all three full Fox hearing Avastin, the response rates are really, really high. They’re really good, but at the cost of complications, diarrhea, issues, with neuropathy, I’m sure anybody who’s gotten Oxaliplatin on this (inaudible). You don’t need me to tell you what the neuropathy is and how that, how that can affect your your day to day well being. And so I think, you know, we have to be really, really careful, because, again, we get really, really good response rates at the cost of complication, you know, and then in the unique scenarios where we can use panetumab, again, the response rates are unbelievably higher compared to not using it. But we have to be really careful, because in some studies, if you’re doing a liver resection and you get some of these drugs before liver resection, it can actually increase your risk of dying from the operation. So all of these things are going on in my head, in our heads, in terms of trying to find the right cocktail, trying to find the right treatment for you. It’s really personalized medicine at its finest, even though it does, you know, it’s the same 2-3-4, drugs that we’re using, trying to find the right ones, and for how long, is really, really important. And so, you know, again, we typically reserve FOLFOXIRI and Avastin if you are really, really healthy, really, really strong. Otherwise, we typically will do FOLFOX and Avastin, or FOLFIRI and Avastin at the expense of higher toxicity. And you know, the unfortunate thing, though, is that the systemic chemotherapy alone rarely allows for conversion to resection. Okay, and so again, I put, I put, I put this here because I just sort of want to summarize chemotherapy helps. We don’t really know who truly benefits. If you have upfront resectable disease, if you have upfront unresectable disease, it might help convert to resectable disease, but you know you have to be really, really careful about toxicity, and then you know the risk of developing complications after liver surgery and involving the liver surgeon early, if it’s one thing you take away from this, involving a liver surgeon early in this process. Process is extremely helpful, because it helps us plan which chemo to use, how much of it to use. What are the goals of chemotherapy? Right? What are we trying to shrink? What are we trying to sort of move away from major blood vessels? What operation are we trying to plan for and potentially avoid if we’re talking about a major liver resection. So I cannot stress that enough, get a liver surgeon to look at your case early. Is it’s extremely important. And again, it just, you know, I love this Michael Scott look, because every time I look at these studies and just it just baffles me that we can’t, we can’t, in a scientific way, show you know, who actually benefits from what. But obviously, you know, chemotherapy has a role here. I’m not trying to say that it doesn’t. Where do the liver surgeons fit in, right? So, so moving on to sort of what we do and what I do, right? So colorectal liver metastases, yes, they have spread beyond the colon to the liver, but it’s a regional problem, right? The liver can be treated regionally, if it’s just there, you know. And surgeons are really, really good at dealing with regional problems, you know. So in 1994 or so, Nancy Kemmeny and, you know, Humon Fong and Les Bloomgard and Bill Jernigan and all these people thought, you know, why not add regional chemotherapy to liver resection? And if you don’t know those names, those are the sort of the people who were at the very, very forefront of HAI chemotherapy at MSK in the late 90s and early 2000s you know. So my pump patients don’t need to, you know, have a reminder, but this is what it looks like. And if you’ve if you’ve not seen it, this is what we do, you know, we put the pump in and the abdominal wall and, you know, feed the catheter to the artery that goes to the liver, and it pumps the high dose chemotherapy into the liver, treating the liver tumors. You know, this is sort of what it looks like when we, when we do the operation. Now, I’m going to warn you, my next slide actually has intraoperative pictures, so if that stuff sort of grosses you out, maybe just look away for a little bit. But this is sort of what it looks like, you know, in the real world, where we, where we put the catheter into the artery and and, you know, you can see the blue dye. I don’t know if you can see my mouse here, but you can see the blue dye in the liver. That’s how we check to make sure that the liver sort of is getting what we wanted to get, you know. So why do we use this? Well, you know, the liver has a dual blood supply, you know, he has an artery and a vein. And we, you know, we know that the normal liver gets most of its blood supply from the venous system. And tumors, especially colorectal liver tumors, derive their blood supply from the hepatic artery, you know. And so we can give chemo directly into the hepatic artery. And this is, you know, from 1951 right? Not new. You give, you give stuff in the artery and it goes to tumors, you can sort of see the liver tumor here, and you see the dye going into the arteries, and the tumor lights up. So what do we use? We use a drug called fudr. You know, it’s a it’s a drug that is similar to five fu but, and it’s not new, but what it allows us to do, and my, you know, my patients on the call hear this all the time, it allows us to give a concentration of drug that’s 400 times strong to the liver. And the reason for that is, is that the liver metabolizes it all, and you know, so none of it gets out into your systemic circulation. And we’re able to sort of blast these tumors with really, really high doses of chemo, you know. And you go back to the original studies from the 1970s and you can see, when you give the chemo in the hepatic artery, the tumor gets much more drug than if you give it in the portal vein, you know. Again, it’s not new. This is sort of the original 1962 this is how they used to do it, you know, thankfully, it looks a lot better and cleaner. Now, you know, these are the, these are the these are the studies that they show. These are the X rays. This is, this is the, for those of you who’ve had the the pump study down in nuclear medicine and the big donut that you sit under, this is what they used to do in the 1960s so, obviously not new. But you know, when do we use it? So we use it after liver resection to treat micro metastatic disease in the liver, meaning disease that we can’t see, that may still be hiding in the liver, after liver surgery that we want to treat. And then we also use it to sort of in a neoadjuvant, or what we call conversion, where we want to convert somebody who may not be resectable yet to resection, because, again, I showed you those initial studies, right? If we can resect the tumors, you’re going to live longer, and increases your chance of cure. And so that’s sort of, those are the ones that we sort of put this in, you know, and we’ve referenced Nancy. And Humon Fong and Les Blumgard, you know, these are the people who who were on this initial study published in the New England Journal of Medicine, you know. And not to belabor the points here, but you know, we compared liver section with pump chemotherapy versus systemic chemotherapy after liver resection, you know. And again, this is sort of looking at, you know, we had a wide range of patients with a wide number of tumors in the study. So it’s a good, broad representation of, you know, who we treat in this in this fashion. And this is sort of just pointing out, you know, we did a lot of big liver surgery back then, right tri segment techniques and lobec, to me, those are big liver operations that we try to avoid at all possible costs these days, if possible. And you can see here that the patients who got the pump, they hai P, they did better, right? They had better two year overall survival. They had better median overall survival. Their recurrence in the liver was much improved with the pump versus not having the pump, you know, and their progression everywhere was better with the pump versus not having the pump. And this study, you know, published in 1999 in the New England Journal of MSS. I mean, this is the seminal study that Nancy Kemmeny published. And she just for those of you don’t know, she just recently retired, though she may be still giving talks on COLONTOWN, I’m not sure you know. And then long term follow up. I mean, you don’t need a magnifying glass to look at this and say, like the patients who got the pump did a lot better than the patients who didn’t get the pump right. This is sort of why we do this, because I think it really gives you all the best chance of having the best possible outcome after a liver operation, you know, these things were sort of shown in the long term, you know. And you can still see that your progression everywhere was better with the pump, the yellow line, and then the liver progression was, was, was much less with the pump compared to without the pump, right? So this is why we do this, and obviously there’s evidence for it, and I use this line in my clinic all the time. You know, it’s the only adjuvant chemotherapy, meaning chemotherapy after liver resection, that has been shown to demonstrate an overall survival benefit, a progression free survival benefit, and a hepatic progression free survival benefit. So really, you know, we should be doing this much more than you know most centers are doing, in my opinion. Okay, again, that’s an opinion, not a fact. Biggest argument that people have with the hepatic artery infusion pump is that, you know, those studies were 20, 30, years ago, and chemotherapy has come much further along since then. And that’s true. There’s no question that we’ve developed new chemotherapy agents, better chemotherapy agents, and we really have not, sort of tested it head to head in the modern era. You know, we’ve had some retrospective studies, meaning, you know, patients who we go back and look, but we’ve never tested it sort of in a prospective head to head setting, you know. And this study is out of the Netherlands and memorial sloane Kettering, you know. And again, the yellow line is pump patients, and the blue line is no without the pump. And you can see that patients with the pump did better. And you know, here, yellow line higher than the blue line means they did better, and they live longer, right? Almost 20 months longer. And you know, the issue with the study is, is, it’s the they use this fancy technique called propensity score matching, and it’s like this really advanced, complex statistical thing, you know, but you got to be really, really careful when you do this, because, you know, I can make anybody look the same, right, if I use these, if I use these characteristics, right, and try to find, you know, two people who would, who would potentially be the same to study and look at, and they’re wealthy and famous. I mean, you get two very, very different kinds of people, right? For those of you that don’t know Ozzy Osbourne on the right, and hopefully everybody knows the person on the left. So you have to be careful with these kind of studies and how you interpret them. And I bring that up, you know, for that reason, because, you know, sometimes you get a lot of people that say, Oh, well, you know, in this study, we compared pump patients with without, pump patients with moderate chemotherapy, and the pump patients did better, and that’s true, but I have to stress that it’s never really been tested head to head. You know, again, a lot of the studies this one was done in 2006 so that was a long time ago, but, you know, it was the only study that demonstrated better quality of life in patients who got pump chemo versus systemic chemotherapy. And as I said, that’s really, really, really important. We see you every two weeks. We pump you full of this stuff, you know. We do these operations, you know, but we need to make sure that your quality of life is good and not enough of the. Studies that we do these days take that into account. And I think, you know, we’re making a push to start including that in our studies these days. It’s really, really important, in my opinion, that we need to take that into effect, you know, and then, and then, you know, when we talk about conversion therapy, for for using the pump, you know, comparing it to modern chemo. Yes, patients who actually were converted to resection did better than than those that didn’t. Furthering, you know, trying to get to liver resection is key. But I think this is the slide that you know that I that struck me the most. And this is the one why I, you know, offer the pump. You know, as much as I do in these scenarios, right? People who got the pump, who had unresectable disease, 52% of people converted to resection. Okay, that’s over half that. That’s sort of unheard of when you’re talking about systemic chemotherapy. Nothing has ever been shown to be that high. Most of the systemic chemotherapy trials or studies that you’re looking at, we’re talking about converting to resection, 1520, 25% when you talk about the pump, 52% okay, and I’m not going to name them, but I know that there’s some patients on the call who we’ve we’ve used this to convert them to resection. And this is why, because it really gets them to where they need to be. And, you know, even, even if we can’t get you to resection, right, you know, you can still get really, really good responses with this, with this pump. And so I’m a big believer of it. Obviously, I, you know, I come from a long heritage of pump believers in New York City, but I truly believe that in the right patients in the right setting for the right reasons, it can really, really be helpful. You know, I showed you this scan, you know. So, these are patients that I took care of in fellowship. This was a 38 year old, a man who who presented after, you know, his son. He was playing soccer with his son. He got hit in the belly, and he had pain, you know. And he had really, really high CEA, you know, his liver was not happy. He got some systemic chemotherapy. He got really, really, you know, bad side effects from it, you know, but he did get some response. We, we, this is what happened after the systemic chemotherapy, you know. We put a pump in, we were able to get him to a liver resection, got his primary tumor out, and he was no evidence of disease for three years. At three years and that I left New York City, so I haven’t had a chance to follow up, but he made it to three years with no evidence that his disease, which is pretty amazing considering where, where he started. This is another patient that I saw when I rotated with Nancy Kemmenyat her clinic. And, you know, presented in 2008 37 year old, you know, had a lot of liver tumors, right? You can see all the liver tumors here. Got treated with pump and systemic chemotherapy for six months, got a portal vein embolization, got two stage right? Hepatectomy, and, you know, 2008 was when she was diagnosed, and she’s NED in 2019. Okay, so this really, really does happen. It’s not a myth, it’s not a it’s not a story, it’s not something that we’re feeding. It really, really does happen. The the biggest issue is, is that we just don’t know, you know, who these people, these remarkable stories, are going to be, right? But they they definitely are there. They definitely happen. And I think that, you know, it happens more frequently in patients who are treated with the pump. Okay, so what? What are my take home points here?

Dr. Padmanabhan 38:50
One size fits all strategy should not apply to anybody anymore. I think it’s really, really important to be really thoughtful about, how are we going to plan this treatment strategy with the ultimate goal of getting to a liver resection? Okay? And it’s really, really, really important to involve a liver surgical oncologist or compatibility or surgical oncologist, whatever you want to call it. really, really important to get that person involved early and then plan the roles of systemic chemotherapy and pump chemotherapy in that plan to get you to a liver section. Those are sort of how, what I think the important take take home points are here. I’d be remiss without you know, giving props to my team so many of you know these people. Dr Siagmore Dr Agarwal, were the two medical oncologists who started this program here at Vanderbilt with me. Sarah is our amazing pharmacist who helps us with the dosing, has helped us develop all the treatment plans and helped us sort of. Try to make this as seamless and as smooth as possible for our patients here, we’ve thankfully recruited several other medical oncologists here, Dr Humon, Dr Gibson, Dr Koloff, to help us with this. We have a lot of people in the infusion clinic help us, help train all the nurses, and we have a lot of people in the or as well who you know behind the scenes make this program, make this program grow. So I cannot This is not a one man show or one person show, and that’s really true anywhere at any of the institutions that do this, you know, yeah, the surgeon definitely plays a role, but, but we can’t do this alone. This is a team sport, and getting the right people on the team, I think, is really, really important. So with that, I’m gonna stop sharing my slides and because I can’t see you guys, unfortunately, if I share and I’m happy to answer questions those that have any.

Betsy Post 41:12
okay, so I’m going to go back to the beginning of the chat and ask some of the questions that are here. Or did you want me to try to take some of the ones that I did get that I sent you an email yesterday too.

Dr. Padmanabhan 41:30
Yeah, Betsy, you do it however you want, I’m happy to, I’m happy to answer any of these. I can stay on for as long as people want. But truly, I really don’t, really don’t mind at all.

Betsy Post 41:40
perfect. Well, one that is actually coming up quite a bit in the liver groups in COLONTOWN is, can we ask him about disappearing disappearing mets due to chemo, and what happens to those if they can’t be resected because they’re gone? So there, this has been coming up a lot lately, and patients have a lot of questions about that. Are they really gone or not gone?

Dr. Padmanabhan 42:06
It’s a it’s a really, really challenging question that we struggle to deal with. In fact, a lot of what I a lot of the research that I’m participating in now sort of focusing on, what do we do about that? How can we find them? How can we detect them? I think people approach it differently. My approach, you know, and the thing that I do, pretty much the night before every operation that I do, is I pull up the very, very first CT scan or MRI before that patient started any treatment. That is the most important. And I tell the residents and fellows that rotate with me the most important scan is the very first scan, because that tells me where all the tumors were, and if any of them disappear, I can still tell where they were based off of that initial skin and so what my approach is, is I try to look for them. And yes, oftentimes I don’t actually see the tumor, but I can sort of figure out where in the liver the tumor was, based off of its relation to other critical structures like blood vessels and bile ducts. So in the operating room, I will actually use an ultrasound and have the CT scan right up in front of me, and I will say, Okay, this tumor was this many centimeters away from this, this many centimeters away from that. Let me find it with the ultrasound. Okay, here’s that structure. Here’s this many centimeters away, here’s this many centimeters away. And I’ll look at that area, and oftentimes I’ll actually see something there. And if I do, I think this will probably answer some of the other questions. That’s where I really utilize ablation, because if it’s that small, ablation is an excellent technique that spares a lot of normal liver, but still treats these tumors extremely effectively. So I spend a lot of time looking for these tumors, looking for where they were, and then treating those areas with ablation and other ablative techniques. Now, some of my patients know that sometimes these tumors, I can’t ablate because they’re too close to critical structures. I think one of the one of the questions that that was asked was the role of irreversible electroporation or ire I think that is a really, really nice technology that allows you to ablate things that are near critical structures a little bit more safely than ablation. Unfortunately, not all centers, like my center doesn’t have ire so I can’t use that. So in that scenario, I tend to use sort of radiation techniques if need. It sort of external radiation. I think another, another question that was brought up was histo trip See, I’m sure all of you have heard about that at this point. I think that histo trip see, is it’s a very, very exciting technology. I think that it’s really, really new and in its infancy, and has not been rigorously or appropriately tested to bring it out into prime time yet. I know that there are a lot of centers out there that have them and are doing the appropriate studies that need to be done to make sure that it’s safe, to make sure that it works, to make sure it does what it claims to do. And I think that that’s great. There are some really big limitations with histo trip. See, mainly the right side of the liver, where it’s covered by the rib cage, you can’t treat as well with histo trip. See, I think in the future, my hope is, is that that company works on intraoperative way to do histo trip. See, that’s down in the road, but hopefully I knocked out some of the questions there. Bottom line, I don’t think those tumors ever truly disappear. I have seen them truly disappear with pump chemotherapy. I have not have them ever truly disappear with systemic chemotherapy. So I try to go looking for them if I can.

Betsy Post 46:20
Thank you. One other question was about diets. So on a scale of one to 10, separately or collectively, how important do you find dietary intake, even a radical diet change, like veganism to help combat cancer recurrence?

Dr. Padmanabhan 46:39
Yeah, that’s a question that I get a lot. Actually, I don’t have any great evidence to say one is better than the other, or one diet is better than another diet. I think this is where, sort of what works for you, right? Like you guys are going through a lot in this treatment process. Your body is going through a lot. It’s going through a lot of changes. And I think the important thing is to eat healthily, you know. And that’s just the standard, you know, don’t eat, you know, the stuff that your mom didn’t want you to eat when you were a kid because your teeth would fall out. Right? Don’t eat that in excess, everything in moderation, and I am not aware of any evidence that suggests that veganism, vegetarianism, or any other diet, is better than another diet. Now, one thing that I get asked a lot is is like, do I need to quit sugar? And the answer to that question is, is universally No, you don’t need to quit sugar. Cancer does use sugar to grow, but it is irrespective of your dietary sugar intake, right it? It hijacks your cells to use the sugar that’s already there. And so you eating sugar, or you not eating sugar is not going to change anything. So if you want that brownie, I love brownies, go ahead and eat that brownie.

Betsy Post 48:02
I’m going to quote you, “eat the brownie”. I love it. Do you see any advances or anything down the road, anything with the HAI pump method of fighting metastatic colorectal cancer, or any brand new technologies that aren’t really being talked about too much, that you see promise in Yeah,

Dr. Padmanabhan 48:27
that’s a great question. I think that the next big thing that we need to figure out is how to get our immune system to attack metastatic colon cancer once it’s metastasized to the liver. Colorectal Cancer once it metastasized to the liver, right? All the studies right now for microsatellite stable which is like 99% of the cancer that spreads to the liver, immunotherapy does not work, and I think it the way that we need to move forward as a medical field, as a surgical field, is figuring out how to get our immune system to sort of get primed in the liver to start, to start tackling these tumors. I think the pump has a unique ability to provide sort of direct access to the liver while bypassing the rest of the body to do that we are, you know, we and others are looking at ways to sort of supercharge the immune system, to sort of seek out and attack these tumors in the liver. We are nowhere near where we need to be, but I think that is where the field needs to go. Even there, even the early studies that have shown promise for tumors that have spread to everywhere else but the liver, where immunotherapy seems to help in those situations, for for reasons that we don’t truly understand, the tumors in the liver don’t respond as well. So we need to figure out how to make that happen. I think the pump could be used as a tool, because it’s a gateway to the liver and bypassing the rest of the body. But we’re not there yet, and we definitely need a lot more progress in that, in that, in that arena.

Betsy Post 50:12
Great. One more question before I go to some of the live questions, it’s interesting. You sort of talked about this, but I do want to ask it outright. So you as a liver surgeon, working with your medical oncologist, you have a patient that perhaps has just one or two mets. How do you make the decision on ablation, IRE, resection? How do you make a decision on those patients with very minimal disease?

Dr. Padmanabhan 50:39
I think that most people, myself included, if you can remove the tumors without having to sacrifice a lot of normal liver, that’s that’s usually the best way to go. I think that ablation techniques definitely have a role in the upfront setting, especially if you’re talking about maybe one or two really, really small tumors that are really, really deep. The problem you know that I have with with ablation up front is when you when we do it percutaneously or through the skin, the ablation zones end up being really, really right. In my mind, the purpose of ablation is to try to minimize damaged liver, right, or removing too much liver. And when you have these massive ablation zones, you’re really sort of, you know, killing normal liver cells that, you know, we want to try to preserve, right? Because we’re playing the long game here, right? We want to make sure that you have enough liver, you know, I would love for me to remove, remove tumors, and the liver tumors never come back, and everybody’s cured and everybody’s happy, right? But realistically, that’s not what happens in the majority of cases, right? We need to play the long game. We need to make sure that we leave enough liver behind so that if it were to come back, God forbid, we have options, right? That’s how I every time that I look at anybody, anybody’s scan, anybody’s story, anybody’s, you know, what they come in and present with, I’m trying to play the long game. And I worry that sometimes when we do these percutaneous ablation techniques, we end up damaging too much liver and and sort of hinder our ability down the down the road. So I try to, you know, if we can remove them and remove them with minimal liver resections, I think that’s the way to go. Ablation has a role, but I think we just have to be really, really careful as a field, not to ablate too big of a zone and really spare the normal liver, because the normal liver is key. Hopefully I answered the question.

Betsy Post 52:57
Yes. Thank you. Let’s see. Is there any data around mortality rates for individuals who were able to have early resection versus patients who have had several rounds of chemo in order to get to the point of resection?

Dr. Padmanabhan 53:17
Great question. We don’t have any, any when you say mortality rates, I’m assuming you mean sort of survival from the cancer long term, and not mortality from the operation itself. I think that that we don’t have a great we don’t have any great evidence to suggest one is better or worse than the other, if it’s a small number of cycles of chemotherapy. Now we do know that as the number of cycles of chemotherapy before liver surgery increases your risk of having complication or liver failure or even dying from the liver resection increases exponentially. So in that sense, your mortality is higher if you get too much chemo before your liver resection. But as I said, I think that you know, for if you have a small number of tumors in the liver, usually less than four is pretty reasonable cut off that most people use, and they are all upfront, removable. The best data that we have says that they should be removed and that you don’t need to have chemo upfront. And so that’s sort of where most, most liver surgeons sort of practice that way. There are unique scenarios, as I suggested, where if you can shrink a little bit and spare a bigger liver resection, then it makes sense. But there’s no data to suggest that you know mortality is or survival is worse in patients who get a few rounds of chemotherapy before their liver section.

Betsy Post 54:50
And I think you answered this one, but I just want to hit this point home, because it comes up quite a bit for new folks in the liver groups. So for some of. With just one or two liver mets, would going to a surgeon before any chemo be a good idea?

Dr. Padmanabhan 55:06
Yeah, yes, absolutely. Because, again, it’s, it’s, it’s all about planning the treatment. And oftentimes, if you have one or two liver mets, you may not need systemic chemo right away, right? And again, we’re trying to play the long game. Every time you get exposed to systemic chemotherapy, it’s giving the chance for the cancer cells to become resistant, right? And if you don’t need it, then why give the cancer cells the opportunity to get resistant to that therapy? Why not save that therapy for if and when you may need it down the road when you have more tumors or tumors elsewhere? That’s sort of my thought process for people who have a small number of liver metastases. And again, it’s never a bad idea to get evaluated by a liver surgeon early, and sometimes that means before seeing a medical oncologist. And that’s okay.

Betsy Post 56:09
Thank you. We have a patient who had a question. She had a solitary liver met five weeks after LAR surgery in 2021 it was ablated, had chemo. So far, all the CT scans have been clear. She did have some lung nodules, but she hasn’t had an MRI Since 2023, and since you know it’s there’s a lot of talk that MRI is the best imaging for the liver. Should she be getting regular liver MRIs in addition to the CT scans?

Dr. Padmanabhan 56:43
So, you know, that’s an interesting question. Yes, I think in general, MRI is more sensitive at picking up these liver tumors than CT scan, especially if you have pre existing fatty liver disease or chemotherapy associated fatty liver disease, I don’t think that getting regular MRIs is necessary. I think that especially if you were able to see the tumors in the first place on your CT scan. Now, there are some people where you just never see the tumors on the CT scan, and you only see them on an MRI. And so I think in those patients, it makes sense, but I don’t advocate getting surveillance MRIs of the liver, sort of just for everybody. I think there are unique situations where where that’s important. We have other ways of detecting, you know, cancer recurrence, in addition to CT scan, so tumor markers, and then, more recently, circulating tumor DNA, you know. So I think that it’s a, it’s a, it’s a combination approach of how we do these surveillance, imaging and and I don’t think that doing an MRI every time is going to be helpful, especially if you can see them in the first place.

Betsy Post 58:06
Thank you. Now, while you were doing your presentation, talking about the toxicity, a couple patients said, is the liver toxicity reversible after chemo is done?

Dr. Padmanabhan 58:17
sometimes and sometimes it is not. And I can tell you, it’s the worst feeling in the world as a liver surgeon, when somebody comes into my clinic and, you know, they got started on, you know, the three or four drug regimen, you know, because they’re they’re young and healthy, and they can tolerate it, you know, and then they develop irreversible liver injury, because then, especially when those tumors were removable, because it I can’t, I can’t safely do liver surgery. When the liver is is permanently damaged. It’s not common, you know, it’s not, it’s not like it happens all the time, I think the incidence is very is still it’s quite low where it’s irreversible, sometimes, most of the time, it is to some degree reversible. But again, I don’t know why you take that chance, especially if you have a small number of tumors that can be removed. I think that, again, getting the liver surgeon involved early can help prevent those scenarios. And, you know, and then, and then, and then making a plan, right? That liver surgeon should be working with the medical oncologist and having a plan right, and making sure that we do the right thing. First, very important.

Betsy Post 59:45
Thank you. So for a patient that has had lung mets in the past, and then liver mets, is there any evidence or studies on the benefit of chemo post liver resection? So for those patients that had had lung metastases in the past also.

Dr. Padmanabhan 1:00:03
I just want to make sure I get it so the lung metastases came first, and then the liver metastases. Is that the question?

Betsy Post 1:00:10
Are there studies on the benefit of chemo, post liver resection for patients who have also had lung mets?

Dr. Padmanabhan 1:00:16
I see, I see. So, yeah, I think that. I think that if you have existing disease outside of the liver, but we’re still going to go after the liver disease, there should be a plan to somehow manage the lung Mets. That plan can involve chemo, but usually, if we’re talking about doing liver surgery in the setting of lung metastases, we’re usually going to be treating the lung metastases with some form of local therapy as well, whether that’s microwave ablation, cryo ablation, radiation therapy, you know, we want to, we want to, we want to do the liver surgery, you know, with a plan to be able to treat the lung disease as well, at least that’s sort of our approach here at Vanderbilt. And so that may involve some chemotherapy to allow for sort of liver surgery, you know, healing time and planning for the lung stuff. But we don’t want to, we don’t want to do again. We don’t want to do too much chemotherapy for too long. And I think that if you have a small number of lung metastases, and we’re going to go after the liver first, doing the liver first, you know, maybe doing a little bit of chemotherapy between and then doing some form of local therapy to the lung would be how we sort of go about doing it here. And so, has that been sort of officially studied? No, it has not. It’s sort of, you know, think this is the best

Betsy Post 1:01:50
Have you seen any research on high fructose corn syrup and the liver?

Dr. Padmanabhan 1:01:56
Ooh, I have not. And admittedly, I have not gone looking for that. So I don’t think that I’m I can answer that any sort of knowledge.

Betsy Post 1:02:07
No problem. Um, when should one do a PET scan after colon and liver resection? What if the pet caught one lesion? Ultrasound caught us, caught seven lesions? Which one would be considered accurate?

Dr. Padmanabhan 1:02:22
Yeah. I don’t usually use PET scan after liver surgery. The reason for that is, is because PET scans pick up areas of cells that are using a lot of sugar. Okay, whenever you have an operation, your body is healing, and whenever you’re healing, those parts of your body that are healing are using a lot of sugar. So the PET scan will light up, and it’s only lighting up because you know you’re you’re healing, your body is in an inflammatory state, and it’s rapidly dividing and using a lot of sugar to heal your operation. And so I rarely will use a PET scan after a liver surgery or even a colon surgery, for that matter, for very, very, very unique scenarios. That’s sort of our approach here, my approach here. So I don’t, I don’t know. I think an ultrasound is sort of the best of those two modalities. The better, the better modality. But if there was any concern about a lesion in the liver, I mean, you’re going to be getting a CT or an MRI, okay, if you come to see me, because, without fail, those are better than ultrasound or pet every time.

Betsy Post 1:03:50
Thank you. This one is I’m very interested in as well. We have a lot of patients that seem to be on supplements. In your experience, do you see any effects of supplements on the liver? I’d just love to hear your opinion just generally on supplements, and what your take is on that for patients with liver meds. Yeah,

Dr. Padmanabhan 1:04:12
I am not an expert in supplements. I do think that some of them certainly have a role. I do think that some of them can cause significant liver injury, and so you have to be really careful. What I tell my patients is that if you want to take them, make sure you keep a list and you run each and every single one of them by your medical oncologist, because that medical oncologist will then run it by the pharmacists, and then the pharmacists go into all their databases and like they compare each one and see which one could interact with whatever chemotherapy that you’re getting. You don’t want to have any issues with liver toxicity, because the supplement is interacting with therapy agents. So if you want to do it, I think you need to be really, really smart about it. And. The list, be honest with that list, and run it by your medical oncologist, so that they can run it by the pharmacy people, because they’ll be able to find the ones with known interactions. They’ll be they’ll be able to tell you which ones those are. And I would recommend not doing that while you’re getting treatment, because the last thing that you want is to have an interaction that then prevents your liver from being able to get you know a therapy that we know is helpful.

Betsy Post 1:05:26
Thank you. So for a patient that is trying to get to resection who has used hai systemic chemo including Cetuximab, what if any recommendations would you make to minimize potential complications from surgery.

Dr. Padmanabhan 1:05:43
Yeah, there’s not going to be a lot that you as a patient are going to be able to do. I think again, the key is trying to get the fewest number of chemotherapy cycles before to get to where you need to get to. You know, there are some interesting stuff that’s coming out of some of the cancer centers in the Northeast about trying to reverse chemotherapy induced liver injury. Nothing has been has sort of been approved in the FDA yet to be able to get there. I think the important thing is exercise, eating a good, healthy diet, making sure you’re not losing a lot of weight while you’re getting all this treatment and staying physically active. You know, your doctor may sort of talk to you about fatty liver disease. Sometimes we will sort of change your diet before liver surgery to try to reduce the amount of fatty liver disease before we get you to the operation. But again, I think the most important things are staying physically fit and making sure that you’re eating a good, well balanced diet, so that you’re not losing a lot of weight. Those are the two things that are within a patient’s control to minimize post operative complications.

Betsy Post 1:07:01
Thank you. I’m really interested in this one too. It comes up a lot. How does a patient select a good liver surgeon? I have one in mind, but I’m not sure exactly what to look for.

Dr. Padmanabhan 1:07:13
Great question. I think you want to look at where they trained, and I think you want to ask them how much they do, how much liver surgery do they do? You really, and that goes for any surgery, right? Like, you don’t want to go get your colon or your rectal surgery from somebody that does one or two a year. You don’t you don’t want to go to a liver surgeon who does one or two a year. And you should ask, you know, I have people ask me, how many of these do you do? How many? How many, how many liver operations do you do? How many have you done? And then the other thing is, you know, I promise, I promise. Betsy didn’t pay me to say this, but, but I tell all my patients to get on COLONTOWN, because who knows better than you? You know, I always tell my patients, you know, this idiot can talk to you about all sorts of things, but I probably haven’t had all those things happen to me, but you all are sort of the community that I on and, you know, and get that information from and you know, you can ask all the patients that I that all my patients who are on here. I tell every single one of them you should get on COLONTOWN If you’re not on it, because it’s one thing for you to hear what I’m going to do from me, but it’s another thing to hear from somebody that’s actively undergoing it, or has undergone it, and I think that that opinion is actually more important. So.

Betsy Post 1:08:50
Gosh, I just love it, and I didn’t pay you to say,

Dr. Padmanabhan 1:08:55
No, you didn’t pay me.

Betsy Post 1:08:56
What would you suggest patient advocates and nonprofits like COLONTOWN, for example, do to help spread this important surgical point of view.

Dr. Padmanabhan 1:09:09
I think just continue to talk to each other, you know. And really, really, really, look, I think, you know, one of the things that we’re doing here is this really trying to figure out, how can we get, how can we get what we do out to the people who need it? Because there are a lot of people that aren’t on Facebook, that aren’t on Twitter, that aren’t on all these, you know, groups that we can’t get this message to. I think, I think really just continuing what you all are doing, you know, holding events, community, getting the word out there, I think, is really, really important, you know, I think what I’ve come to learn over the years is, is that, you know, doctors, doctors sort of get really entrenched in sort of the way they do things. You know, they’re in their. Small community and and, you know? And I’m calling other people out without calling me out, you know, we really rely on, on on, I think we really should rely on patients to sort of help us figure out where we need to improve. And I’ll give you an example I didn’t even know what histo trip, see, was, I hadn’t heard of it. I had not come across any of it, any of it in the in the journals and things that I read. And there was one clinic, like, in end of January or February, right? I think I had like, four people come in, and they asked me, Do you do I do histo trip? See, I’m like, I don’t even know what that is, but what did I do? And I go look it up. I, you know, read about it, I learn about it. And, you know, and I wouldn’t have done that if a patient didn’t ask me, you know. So, so I think, I think, you know, keep challenging us, keep forcing us to sort of, because you guys are all over it, right? Like you read all the stuff. You know, I’m, I’m standing in an operating room for 12 hours a day usually, right? I’m not, I’m not like out there looking at this stuff all the time, you know. So, so challenge us, you know, keep, keep forcing us to get better. I think that’s really important.

Betsy Post 1:11:12
Q2, people were asking, how much damage does the pump chemo do to the liver to complicate future resections. Yeah,

Dr. Padmanabhan 1:11:22
it’s not free, for sure. I think the biggest thing that we worry about with pump chemotherapy is not direct liver toxicity, but it’s bile duct toxicity. And any of my patients tell you that that’s what I’m that’s what I’m concerned about, right? So the pump chemotherapy does a really, really good job of treating the liver tumors, but it also does really, really good job if we’re not careful, to sort of injure the bile ducts. Now, thankfully, if the bile ducts get injured, we usually have ways to treat it and fix it, and that involves, you know, stents and, you know, endoscopies and things like that, but, but But you have to be really careful. And sometimes we’re really careful, and it still happens, you know, you sit there, you monitor the liver tests and the in the blood work every two weeks, and you put the steroids in the pump and all that stuff, and you do all the things that are right. And sometimes it happens anyway, right? But I think that’s the thing that we worry about, is the biliary toxicity, you know. And I think that’s where the experience comes into play, you know, really, really understanding the nuance of what the liver tests are doing, what the what the Alkaline phosphatase is doing, and understanding how to dose reduce, how to hold the doses at the right time. And I think that’s where the experience comes into play.

Betsy Post 1:12:41
And I think I’m down to the last two questions here, and they’re very similar. So one person’s asking if I’m no evidence of disease based on my latest MRI, but I’ve had to resect two, respectable two ablated tumors in the past. What do you think about getting hai as a preventative measure even though I’m Ned now, or should I wait until more tumors pop up?

Dr. Padmanabhan 1:13:04
I think you wait, because we don’t know if you will benefit, based off of the studies that that we have, in the studies where the pump showed benefit, the pump was started within two to four weeks after liver resection, so I don’t, I can’t, I can’t tell you if it would work or not for you, and therefore, if I don’t know, then I shouldn’t be experimenting at you, just sort of willy nilly, in my opinion. I think it’s an interesting question, and one that I’ve thought about a lot, but we don’t have a good answer from a rigorously, you know, performed study to be able to answer it.

Betsy Post 1:13:53
And I think that answers the other one, because the other one is basically when the the Mets are no longer visible, and scans and blood work, you know? I mean, I guess you’re saying I can’t treat what I can’t see,

Dr. Padmanabhan 1:14:05
you know. So I in those scenarios, I usually say, let’s wait, you know? And if something comes back, and it’s a liver, we can cross that bridge when we get there.

Betsy Post 1:14:16
There’s one more that I actually have, one too. What percentage of resection plus pump patients. Do you do robotically or laparoscopically? And how do you decide that versus open? Yeah,

Dr. Padmanabhan 1:14:28
laparoscopic zero. I don’t do any laparoscopic liver surgery. That’s there. There are few people, I would say in the world that do that and do it really well. I am not one of them. I do do, I do do robotic liver resections. We did our first robotic pump in at our program a few months back. I think that it’s sort of, it’s sort of robotic surgery takes longer, okay, especially with the liver, because you’re. Limited by angles that the robot can get to certain places in the liver. And so I think it becomes a law of sort of diminishing returns, right? Like if you’re in the operating room for 14, 16, 18, 20, hours to do it robotically, there are risks associated with being in the operating room and under general anesthesia for that long. And so I’m very selective in who I do robotic liver resections and robotic pumps in and I think a lot of it depends on whether or not you’ve had open surgery before. So is there going to be a lot of scar tissue that I’m going to have to sit there and cut through robotically that’s going to increase your operative time, increase your risk of having a general anesthesia associated complication? If you have a lot of tumors that we’re trying to remove that can increase operating room time, it can change, you know, and you can’t with the robot, you can’t really utilize ablation techniques as well, because it’s the technologies just don’t mesh yet. So if I have to do ablation, and a lot of ablation. Usually I’ll do that open if I’m just putting a pump in and nothing else. Often, I have switched my practice at this point to doing it robotically, so that’s sort of how I decide with that.

Betsy Post 1:16:17
So my question has to do with Dr Kemmeny was pretty specific about her protocol she had, and I may mispronounce it, so just I apologize in advance, but she did put her patients prophylactically on protonics and Ursodiol. That was just standard for her. And what I’m seeing with the new pump programs that are opening up. It’s not consistent. Do you have an opinion on that?

Dr. Padmanabhan 1:16:44
We definitely do. Protonics, the literature is pretty good. Ursodiol is a little bit of a wishy, washy thing. In my opinion, I usually will reserve it for when people have symptoms of biliary issues. I don’t, because people don’t. It’s not a great drug to take. It has just doesn’t. People don’t like it very much. But to my patients out there that are on it, I’m sorry that I’m doing that to you, but, but, but, but, yeah, I don’t, I don’t do it. We don’t do it routinely, the Ursodiol, we definitely do the PPI, the protonic. So the omeprazole, for sure. So, okay, there’s no, there’s no, I love Dr Kemmeny. I still have to call her Dr, Kemmeny. I love her. You know, she certainly has the most experience in the world. But the there’s no, there’s no real good evidence for the for the Ursodiol. So.

Betsy Post 1:17:41
it’s okay to have a different opinion. It’s okay. And one last one that I see, did you want to talk anything about? We’ve talked a lot about ablation. How do you make the decision between something like SBRT for a small met versus ablation?

Dr. Padmanabhan 1:17:59
Yeah. I mean, I think if I can get to it safely, I will try to ablate it, microwave, ablated. Here we, you know, SBRT. I typically will reserve for tumors, for for reasons, you know, whatever reason that I cannot get to to do an ablation, or if, you know, people have had a biliary issue and they had to have a stent or something like that. You can’t really ablate people after they get stented. Microwave ablate, I should say. And the reason for that is because you’re a very, very high risk of developing liver abscesses. And so in those scenarios, I will tend to use radiation if I need to sort of treat smaller tumors when they have, when they have had some sort of bile duct intervention, stent, ERCP, etc,

Betsy Post 1:18:52
Well, I know you have done such an amazing time this evening, and you have been so generous of your time away from your family, you know, resting, relaxing, eating some brownies. So hopefully you can see your patients up there. I don’t know if you can see them, but they’re waving at you. They sing your praise. In COLONTOWN, and we just really appreciate you being here tonight, being so generous with your time and your information, answering everyone’s questions and being so patient. So I just want to thank you on behalf of all of your patients and everyone in COLONTOWN that gets to benefit from this.

Dr. Padmanabhan 1:18:59
Thank you for the opportunity. I do want to end with one last thing so Mike Lidsky, who is sort of a few years senior to me, at Duke University, is opening, has opened a very, very important clinical trial involving the pump, and it is going to be the first trial that’s going to compare the pump to the modern systemic chemotherapy in patients who have unresectable liver metastases, okay, really, really important trial, and I think that this community would be really, really helpful in sort of getting patients with that disease to be evaluated for a pump on that trial. Really, really important, really, really important study that we need to do, and we need to accomplish as a group, and this is where I think we as doctors and surgeons can work with the community and the patients and and I think it’s really, really important that we we do that. So I wanted to mention that Linsky has put a lot of hard work. I know Betsy. Betsy knows Mike, and he’s put a lot of hard work into that, and we’re going to open that trial here. And I know a lot of other centers are as well. I think really, really important to do that.

(Video begins mid intro sentence) ….Histotripsy. But when I was speaking with him and preparing for the talk, he had mentioned that he really thinks it’s important for patients to understand not just histotripsy by itself, but all of the different liver directed treatments that are available, so patients can really make wise, informed decisions be part of their care. So I really want to thank him, on behalf of COLONTOWN for being here tonight, and I’m going to turn it over to him in just a second. I want to make sure everyone knows how it’s going to work. So Dr. Rocca is going to speak to us, present to us, give us his wisdom, and if you have questions for him at the end, there will be a time for questions. Please use the chat feature here in Zoom; You just click “chat” and add your question to the chat. The questions will be held to the end of the presentation, and then at the end, when we have time for Q and A, I will read the questions to him, and he will answer those questions. So without further ado, I’m going to turn it over to Dr. Rocca. Again, thank you for being here – we’re so excited to learn from you.

Dr. Juan Rocca 1:09
Thank you so much Betsy for inviting me to speak, and I hope that I can help you figure out different treatment options. I think that you know, here at Cornell, we are a division of surgeons that do liver surgery, liver transplantation, histotripsy. We work hand in hand with our oncologists and interventional radiologists with ablation, our radiation oncologists with radiation. And once a week, we have a meeting, which is called a multi disciplinary tumor board, where we bring our cases, and we have the input of absolutely every physician that is involved in the care of colorectal cancer. I think it’s an amazing meeting, because it really tries to bring the best treatment option for each individual patient. And this is the purpose of this talk today. I think that it’s important to try to clarify – I have no conflicts, – but I just wanted to clarify the purpose of the talk. I think that many of you may know about one or two options that were presented to you, but not all of the options. Maybe you feel you’re being boxed in, the care you’re getting, where you went to get your first consultation about the treatment of your situation. So the main purpose of this talk is to — you geta lot of different treatment options but then, many of you also may know about all the different options, and may be really confused about what is the best option for you, or if you want to know more about the benefits and the risk of each of the treatments or combination of treatments. And finally, I hope in the different situations I’m going to be presenting, I hope that you can relate to those situations, and you can decide what of these options may be working best for you.

Dr. Juan Rocca 3:38
The outline of the presentation has multiple components. First, we’re going to do a quick overview of the treatments that are available for colorectal liver metastasis. This is only metastasis to the liver, which is the main focus. Then we’re going to be discussing what is the gold standard in the treatment of colorectal liver metastasis, which today is a combination of systemic treatments, which is mainly chemotherapy and targeted therapies and surgery. That’s what weconsider the gold standard. From there, we have a lot of data about how that works, and from there, we can move on to other combinations of therapies when surgery is not a good option. For that, we need to discuss, what is resectable disease. That is disease that can be treated with surgery, versus unresectable disease. And then we are also going to be discussing the role of ablation. You’ve probably heard about ablation, different types of ablation, but ablation can be done with microwaves or radio frequency, and this can be used with surgery or can be used for resectable disease, but also can be used on unresectable disease. Then we’re going to go over the role of other local, regional therapies and the different combinations of them. We’re going to discuss the role of liver transplantation. It’s a very strict criteria for liver transplantation, but we’re going to go over that. And finally, we are going to discuss how histotripsy, can contribute to this multimodal management of colorectal liver metastases. It’s a new technology, it’s quite promising in many aspects, and everybody’s embracing it now. We don’t have too much data to really put it against the other treatments, and so it’s important to disclose that. It is promising, it is exciting, I do it quite often, it’s just that sometimes it’s hard to offer something that we don’t have complete proof that it works in the long term. So that’s why I left it for the end.

Dr. Juan Rocca 6:10
Okay, so let’s go with the treatments available for colorectal liver metastasis, starting with what we call the systemic therapies, which today is a mix of different regimes of chemotherapy. All of these sound familiar to you: Folfox, Folfoxiri, Folfiri, Capox; and different targeted therapies like Avastin, Cetuximab, Panitumumab, Pembro. And all these regimens can be combined depending on the different type of mutations that the tumors may have, like the MSI status, the RAS mutations, the BRAF mutations that are of worse prognosis. But now there are more trials and treatments for BRAF mutations, HER 2 mutations as well. The systemic therapies are the backbone of colorectal liver metastasis. In the past, we used to probably use it only in some situations. Now it’s pretty much in every situation. Now for locoregional therapies, I always include surgery as a locoregional therapy, because at the end of the day, when we do liver surgery, even liver transplantation, we are treating the disease in one spot in one region, so it’s a locoregional therapy. So it probably is better to divide it in those locoregional therapies that require an operation, require surgery like resectionwhich is surgery, with or without ablation. We do ablation at the time of an operation, an open operation, a robotic operation. We can do ablation on a laparoscopic operation. We can do ablation together with resection. We’re going to also touch on the role of the Hepatic Arterial Infusion pump and liver transplantation. All these require operations. And then some therapies that do not require an operation is also ablation, which can be done percutaneously with the interventional radiologist. Y-90 radioembolization, which is an injection of material with radioactive activity into the liver, radiation- external radiation and histotripsy.

Dr. Juan Rocca 8:36
So first, the management of colorectal liver metastasis in the last 20 years has improved significantly. The survival of patients who have colorectal liver metastasis improved for three reasons, mainly because we have much better chemotherapy and immunotherapies and different targeted therapies. We have been a lot more aggressive with the surgery that we perform for colorectal liver metastasis, and we also have better locoregional treatments that we’re going to go into in a little bit. But if you look at the last 20 years, the number of operations we’re doing for colorectal liver metastases has increased significantly, and when you divide those patients that made it to surgery versus those that could not have surgery, that’s a striking difference in the survival. So that’s why today, being able to say that we have resectable disease is really very important, because it impacts the prognosis, it impacts the survival and most of the survivors, we’re going to try to put it at the five year mark, which is what most of the papers are usually able to measure or compare survival of different combinations of techniques.

Dr. Juan Rocca 10:02
Let’s try to define resectable disease first. So, resectable disease is that, the tumor in the liver, or the tumors in the liver can be removed or treated with liver surgery. The goal of resectable disease is to get to a condition called NED, which is “”no evidence of disease”, because this is associated with the longest survival. If we can bring you to NED, even knowing that the tumor may come back later, each time we bring you to NED we are giving you the best chance of having the longest survival. Now, resectable disease may require systemic therapy before surgery more and more. In the past, we used to discuss that some situations were benefited, first with surgery and then chemotherapy. But now the data is moving more towards trying to do systemic therapy and then surgery in the liver, mostly when you have a higher number of tumors in the liver. Sometimes they require more than one operation. We call this staged hepatectomy, or staged operations, or a combination of an operation with a locoregional treatment afterwards, in order to get you to the NED status, and one of the conditions is that the patient has to be able to go through an invasive procedure and surgery.

Dr. Juan Rocca 11:31
Now, on the other hand, unresectable disease is the opposite of this. The tumors cannot be removed or treated with liver surgery, or we can, but by removing them, we are not going to be able to bring you to NED. We cannot get rid of all the disease, and this is usually conditioned by the number, the size and the location of the liver tumors. Sometimes you have small tumors that are in a poor location inside the liver that require a major operation of the liver. So that’s when other techniques may really be able to bring you closer to resectable. Sometimes due to the condition of the liver, the chemotherapy can be toxic, can give you fatty liver, can give you fibrosis, can give you some scarring on the liver, so the liver may not be able to tolerate a big operation. Sometimes, when we do systemic therapy, it’s a good test of time to understand the biology of that tumor, and if the tumor progresses while on chemotherapy it’s telling us that doing surgery on that liver tumor is probably not going to help too much, so that could be a reason for being unresectable. Technically, we can do the operation, but the biology of the tumor is telling us that it’s not going to help the operation. Sometimes you have disease outside the liver that dictates the survival more than the disease in the liver. And you can have disease outside the liver, for example, in the lungs. The disease in the lungs is quite indolent and easy to manage. The disease in the peritoneum, it’s difficult to make it respond to chemotherapy,…bone disease, etc. So there are different situations which require a multi disciplinary decision about what the best treatment option is. I want to highlight this, because again, in the past, and not long ago, we were discussing if pre-operative, systemic therapy before liver surgery was a good thing to do. And yeah, maybe for a single lesion that came years after removing the colon, and has a slow progression, maybe you can argue that you could do an upfront resection and then do chemotherapy later. But more and more data is coming out that the use of systemic therapy, mostly when you have a bigger number of lesions, is really important in making disease more controllable for surgery, and that improves the recurrence after the surgery.

Dr. Juan Rocca 14:50
So this is a nice study: It’s about 1000 patients that were matched between those that had only chemotherapy versus those that have had chemotherapy and surgery, but they were much based on the size of the tumors and the number of the tumors. And there are different scores that are standard, the CRS score, the TB score, the Game score. These are different scoring systems that we have to assess risk of liver metastasis and the risk of recurrence. And clearly, those that received chemo before the surgery did better in the overall survival, and did better if you look at the recurrence free survival for the first two, three years. The two groups were about the same, but then, after three years, they started spreading again. And those that didn’t receive chemo before surgery had less recurrence free survival than those that received chemo. So I think this is a one of the many studies that now are showing the benefit of having systemic treatment before surgery.

Dr. Juan Rocca 16:06
Now, a few other concepts of surgery in colorectal liver metastasis. First is, we want to resect the tumor with clear margins. That means that we want to cut the liver where there is no tumor, but we also want to leave enough liver volume. Clear margins for colorectal, liver metastasis can be as little as one millimeter. That’s enough, even when a tumor is sitting in a blood vessel near the liver, if we peel it off, that’s enough, too. So it’s not that we need to do a lot of surgery around the tumor. And this is important. The type of surgeries that we usually do, any liver surgery, we can have what we call the West Resection, where we take a little piece where the tumor is sitting. Or we can start taking segments of the liver. The liver has eight segments. And we can take, for example, this will be 25% of the liver. This will be almost a 35-40% of the liver, the left hepatectomy, the extent the left hepatectomy is almost 70% of the liver. We have different sections of the liver. So typically for colorectal liver metastasis, we try to avoid doing anatomical hepatectomies. We try to go around the lesion. The type of surgeries that we usually do for colorectal liver metastasis here in the first column, the Type A, is what we call the parenchyma sparing liver surgery. That means that, knowing that we need to have at least one millimeter of margin, we go around the lesion as many times as we can. Not always we can. Sometimes the lesions are too big, like you can see in the B column. And if the lesions are too big, either we are forced to cut the right side of the liver, for example, and remove maybe 60% of the liver. Or sometimes, if we feel that the rim on the liver is not enough, we might need to do some intermediate steps like what we call portal vein embolization, to deprive blood flow to the site of liver we’re going to remove and let the other side grow before doing the operation. Sometimes we do the two stage liver surgery when we have multiple lesions on both sides, we first do an operation on one side and we remove, for example, here, these two small lesions on the left side. We remove them, we wait for the liver to grow, and then maybe six weeks or eight weeks later, we can go back and remove the entire right side with all the lesions. But these are goals of surgeries with the goal of bringing the patient NED, without evidence of disease.

Dr. Juan Rocca 19:07
And this is the “ALPPS” procedure, which is another two stage procedure where we cut the liver halfway, we don’t cut it all, and we remove the tumors, and that will accelerate the growth of the liver. Instead of in six to eight weeks, we can go back in two weeks and remove the other side of the liver. Again, as you can see, the complexity of these operations increases when you have a bigger size of tumor, or a bigger number of tumors, or both sides of the liver. But these are all techniques that we use to be able to bring the disease to zero, at least with the method that we have today to see disease, which is CT scan and MRI or PET scan.

Dr. Juan Rocca 19:54
Now, why is it important to save as much liver as we can is because when you have multiple tumors, 70% end up coming back at some point. And if our goal is to prolong the survival as much as we can, we need to have enough liver to keep treating that liver. We sometimes do a second surgery in the long term, like two years later, or even a third operation to take care of new lesions that are coming back after a while.

Dr. Juan Rocca 20:37
But then also, it’s important to understand that ablation has a big role here because those patients that – when the tumor comes back, they could have a second operation or an ablation to treat the tumor, they have a better survival in the long term. Those are the ones that we manage to bring to the five year mark. I think it’s important to understand that sometimes patients that have resectable disease have the best prognosis for a five year survival, but many times may require more than one operation, more than one procedure, while still receiving systemic therapy. Okay, this is how we get you there.

Dr. Juan Rocca 21:14
This is just a study to show that the difference between doing a measures hepatectomy, like cutting half of the liver, versus doing a parenchymal sparing hepatectomy and ablation to take care of many lesions. And this is an important study that show that when you compare those strategies, they have the same survival, and the patients that have a parenchyma sparing hepatectomy and ablation have less complications than those who have a major hepatectomy, which is important. This is an important number here, back in 2014 only 31% of the cases were being done with parenchymal-sparing surgery and ablation. And that rose to almost 50% in 2022 which is is an important trend. We really use ablation a lot when it comes to colorectal liver metastasis. And this is a study that came out this week, actually another multicenter study that compares the role of ablation or surgery. When you are talking about tumors that are three centimeters or less in size, they have the same outcome. Okay, it’s not inferior to do ablation versus resection. Resection is a gold standard, but now ablation, up to tumors of three centimeters, is equivalent. And this is really important, because sometimes, if we do an operation, we clear your tumor, and in a year or two later, you have a new tumor coming back, you might be able to get away with ablation, without surgery.

Dr. Juan Rocca 23:01
Or if I do an operation and to treat three tumors, and I can safely remove two, but the third one is in a tough spot, or I may require to remove more liver, I can do an ablation of that tumor. That is equivalent, as long as the tumors are three centimeters or less, this is another important thing, as we have a higher number of tumors in the liver, we have less chance of surviving in the long, long term, or a higher size of tumors. This is the liver met survey registry. It’s the largest registry in colorectal liver metastasis. I wanted to show you that these are the things that we always consider for puttingsomeone in the category of being resectable or being unresectable. If sometimes, technically, we can remove all these lesions, but they tend to come back, resectability is not only a matter of a technical surgery, it’s also had to do with the tumor biology and the number, the size, but also how long it takes for that tumor to come back. Sometimes when we do operations and we have what we call the very early recurrence after we do an operation, we get the patient to NED, and then in about three months, we have a new new tumor that is telling us that the biology of the tumor is aggressive, and that usually is associated with the number of lesions that we have, or if there’s any extrahepatic disease, or if there’sany mutation, and it’s sometimes important to the surgery. The outcome after the surgery will tell us a bit more about the biology of that tumor, and that will guide our decisions about what to do next. So, in summary, liver surgery for resectable scenarios, I think it’s always important to understand that surgery always has risk. Liver surgery is always complex, even if we do it small, as small as we can. But you know, it offers really good long term outcomes. 50% can achieve long term survival after a successful resection, always, in my opinion, combined with systemic therapy, and it’s also important to understand that many of these tumors are going to come back in five years-60 to 70%, and that’s why we need to keep treating it as aggressive as we can.

Dr. Juan Rocca 25:44
Now, what happens for those that we consider that we cannot resect, that it’s beyond all these different scenarios that I just showed you where we can do an operation or an ablation? Well, first, I think if you do systemic therapy alone, chemotherapy and now with targeted therapies, the survival at five years is about 20%. But still, it’s important to understand that this is the backbone of the multimodal treatments. Over that backbone of systemic therapy, we can add the benefit of other locoregional therapies that can improve the survival. And those other locoregional treatments can be ablations that a non surgical ablation, percutaneous ablation, Y-90 radioembolization and external radiation. So a brief description of each of these. Ablations can be done with radio frequency or microwaves. We put a needle inside the tumor in the liver, and pretty much we burn the tissue. So that pretty much burns the tumor tissue and the liver tissue that is around with the margin. So the same thing we would do in surgery to make that tumor cells dead. That can increase, maybe 10% more the survival at five years if we combine it with systemic therapy. Now we don’t have a lot of data about Y-90 radioembolization at five years. But yes, we use it when we have tumors that are more than threecentimeters where ablation doesn’t really do a good job. And we inject the tumor inside with radioactive particles, and the tumor slowly gets radiated and becomes non-viable or dies. These injections can be done very focal at the level of the tumor or in different segments. Sometimes for liver transplantation, we use it in the whole liver to keep the tumor at bay until we get to a transplant. I think it’s really an important treatment, and it’s always important to consider.

Dr. Juan Rocca 28:13
And then we have the external radiation or SBRT, which, again, we don’t have long term data. We usually reserve for those patients that cannot receive other treatments. But yes, we do know that it’s able to achieve good local control of the tumor, at least in the first two years when we radiate a tumor in the liver. So I want to bring to the discussion also the role of the hepatic arterial infusion pump, which nowadays is not just that. It’s combined also with systemic therapy, but you’ve probably heard about this usually for unresectable disease, when you have tumors that are on both sides of the liver and multiple tumors. It’s a good method to downstage tumors to decrease the size and the number and sometimes convert them to resectable. So what it does is, because the chemotherapy is usually toxic to the entire system, we give only some specific chemotherapy into the liver, and that first passage into the liver will make the chemotherapy concentrate in the liver only and not give toxicity to the rest of the body. It does have survival benefits, because about 50% of those that receive a hepatic infusion pump may be able to be downstage to the point that they can be converted to surgery.

Dr. Juan Rocca 30:04
When you put it all together, the latest studies the overall five year survival for unresectable disease with the pump is about 50%. But then if you divide into those that responded to the pump and the systemic therapy and were able to have surgery, those had a survival of about 70% at five years. But then the other ones didn’t respond. It’s about 50/50. The other half that did not respond didn’t make it to the five years. But again, these are not only therapies that allow you to downstage treatment, but also to be able to understand the biology of the tumor. And those tumors that respond, they have a shot at having surgery or even transplantation, and those tumors that do not respond, at least we try very aggressive therapy, and if they do not respond, biology wasn’t clear.

Dr. Juan Rocca 31:09
All right, so now liver transplantation. Liver transplantation is the most radical treatment for liver disease from colorectal liver metastasis, and that’s why we call it the ultimate liver correctional treatment. Because what we do is, we take care of some cases of unresectable disease, liver transplant should not be offered to those that have resectable disease, because they have very good survival. But those who have unresectable disease, and they have a five year survival below 50%, below 30% some of them, they could benefit from having a complete removal of the liver, and by removing the entire liver, we’re not only removing the tumors, but also we’re removing the factors that are in that specific liver that allow the tumor to come back. Okay? So that’s the rationale behind it. But of course, for that, you need to be able to have a disease that is well controlled, right? So it’s kind of a long pathway to get to transplant, and many times all these different techniques that I told you beyond surgery, like ablation, like a radioembolization, or Y-90 radiation, or even the hepatic arterial infusion pump, are methods that we use to keep the disease at bay so we can make it to transplant. We use a lot of time, as a test of time, to tell us that the biology of that tumor is manageable to the point that we can do a liver transplant and not have an immediate recurrence, Okay?

Dr. Juan Rocca 33:08
So this is the latest study that we have in transplantation. We have some data from the United States. We have data from Norway, which were the pioneers on this more than 10 years ago, but this is the study that came out last year in 2024 and it’s a multicenter study in different countries of Europe. They show that if you tranplant patients with unresected liver metastases under central criteria of the stability of disease and the disease has to be restricted only to the liver. You cannot have peritoneal disease, you cannot have bone disease, you cannot have lung disease. So with that criteria, when they looked at the intention to treat, this is all the patients that were recruited to the trial. The five year survival was 56% for those that received a liver transplant, versus 12% for those that only received chemotherapy. Now, when you start tweaking a little bit the criteria to make it stricter, then the five year survival – that’s what they call the “per protocol” survival – the five year survival went up to 73% when you did liver transplant and chemotherapy, versus 9% for chemotherapy alone. So this is important, because this 73% is beyond what we consider the survival benefit of a liver transplant, which is about 60% at five years. Remember that liver transplant is a standard practice for many other diseases. It started with liver cirrhosis and many other diseases that are not related to cancer or some diseases that are related to liver cancer from primary liver tumors, and they have a high standard of survival. The survival of the liver transplant at five years nowadays is about 80% for most of the indications, and for some cancer indications about 70%. so it’s hard to really start doing liver transplants for colorectal liver metastases if you are going to be having a five year survival that is be below that benchmark of about 60%.

Dr. Juan Rocca 35:38
Now the other thing I wanted to show you about this data is that, as you can see, on the progression-free survival “per protocol”, those that received a liver transplant, with the red dotted line, they did have recurrence. They have a fair amount of recurrence, but by two years, 50% have some sort of recurrence, and we’re going to talk about that. Much of that recurrence could be treated. So if you can treat the recurrence after liver transplant, you have this concept that we have here, is the secondary progression-free survival. That is how you prolong the survival after treating the recurrence. So we’re going to go a little bit deeper into this and talk about the recurrence patterns after liver tranplant, and the difference with the liver surgery. If I do liver surgery for colorectal liver metasteses, the primary site of recurrence will typically be the liver because the liver that I did surgery on still has the conditions for a new tumor, and is harboring microscopic tumor or new tumor to be seeded and grow back and recur. Okay? When we do a liver transplant, not only are we removing the tumor, but we’re removing that liver with those factors, and we’re putting in a different liver that may not have those factors. So the recurrence pattern after liver transplant is not in the liver, it’s mostly in the lungs. And as I told you before, the lung metastases are indolent, usually they take a long time to progress, they are not as life threatening as a metastasis in the liver or the bones, or the brain. So it is important to consider this when we know that some patients have lung metastases after liver transplant, but they can be treated with surgery.

Dr. Juan Rocca 37:51
This is an example that I want to show you. This was done last year in Chicago. I trained in Northwestern Memorial, actually, many years ago, and a young patient that received a liver transplant for colorectal liver metastases was 8 years out from that liver transplant without problems, except for some lung metastases that had recurred and was stable, but they kept coming back after different treatments. So for the first time, it was decided to do a lung transplant for metastases in the lung, 8 years later after a liver transplant. So this is way far from what we consider standard of care, but at least it’s giving us a glimpse of what we could achieve by having a long term survival for unresectable, colorectal liver metastases.

Dr. Juan Rocca 38:52
Of course, we have to be very cautious with all this, and unfortunately, the patients that can be eligible for a liver transplant, the patients with colorectal metastasis, about 1 or 2% of all the patients that are there. So this is an important figure that can give you a sense of all the patients that have colorectal cancer, half of them have colorectal liver metastasis, about 30 to 50% of them have no evidence of extrahepatic disease, which means that we could consider liver transplantation. But you know, 70% of them are technically resectable, so we should resect them. And then there’s the 10% that, if we consider all the selection criteria, may be able to be considered for transplantation. But then, in the end, through the pathway of transplantation, which requires a wait time or requires treatments, requires them to go through a transplant evaluation and to receive an organ transplant from either a live donor, or a diseased donor, only 1 or 2% may be able to receive it. This is encouraging to be able to come with liver transplant, but still, it doesn’t have the scale to impact everyone. This is just to show you the protocol that we have at Weil Cornell for transplantation of colorectal liver metastases. We have a trial that is listed in the clinical trials.gov site. We did transplant five patients, but we did evaluate, (this is a bit old), more than 35 patients. The definition of unresectable is made at the tumor board. We look at the imaging, and we have surgeons, we have oncologist, we have interventional radiologists, and we come up with different strategies to decrease the tumor burden and see if there is a way to resect this patient and make them NED. If we don’t find a way, then that patient, if they only have disease limited to the liver, that patient may be able to go into liver transplantation. For that, we need to have different tests of the lungs, the liver, a PET CT, we usually do six months of chemotherapy, and we have to make sure that the disease remains stable or responds. And then sometimes we have to remove the primary tumor. If the colon tumor was still there, we had to remove it and wait and give another treatment session. And then closer to the transplant, we typically give lobar Y-90 which is this radioembolization to the both sides of the liver, because at some point we need to stop the immunotherapy before the liver transplant, and we need to wait about six to eight weeks for that immunotherapy to go away. We want to have some control in the tumor with with the Y-90. That’s why we usually give it. The product Y-90 is quite toxic to the liver, so we have a little window there to stop the immunotherapy with the effect of the Y-90, and then do the liver transplant.

Dr. Juan Rocca 42:13
This is a summary of the outcomes of different scenarios for colorectal liver metastases. So starting with the easier scenario, single liver metastasis, you can have a five year survival up to 60% with surgery and systemic chemotherapy. If you have multiple liver metastases that are resectable, you have a combination of different treatments and as I told you, you can have survival rates that go between 40 to 50% at five years. If you have multiple liver metastases that are unresectable, your five year survival can go from 10 to 20% if chemo only, up to 30% if you add ablation or chemoembolization or radiation to it. If you have a hepatic arterial infusion pump, your overall survival can stretch to 50% or more. It depends on if you respond to the arterial infusion pump. If you don’t respond, your five year survival won’t get to five years. It’s going to be hard, but you might be able to respond and become eligible to either having surgery or a transplant, for some cases, we do consider patients that are being downstaged with a hepatic infusion pump, we do consider for transplant in some situations, and then liver transplantation, if you make it to liver transplantation again, 1 to 2% only can make it there. You can get up to 75 to 80% of five year survival. It doesn’t have the scale, but yes, it’s very promising for those that can meet the criteria.

Dr. Juan Rocca 44:10
So now let’s put this into the right context. I think this is a great picture to tell us what the scale of all this is. Okay, so unresectable here at the bottom, if unresectable are in the 10,000, resectable is about 10% of that, in the 1000s. Okay, so the resectable disease as we define it, that we can do surgery, combined with chemotherapy, maybe with ablation, the tumor comes back, we do surgery again or ablation. That is in the proportion of the 1000 compared to the 10,000 of those that cannot have resection or cannot become NED. Then those that may be considered for liver transplantation are in this grey zone. Yes, they are not resectable, but the burden of disease is not too much, or the biology of the tumor is not too aggressive, like, for example BRAF mutations are not being accepted for liver transplantation because they are too aggressive, but some other RAS mutations are being accepted. And of course, there’s a test of time, etc. So, liver transplantation would be in the 10’s of transplants, okay. So this is just to give scale to, or to give a good context of the different treatment options.

Dr. Juan Rocca 45:45
Okay, now let’s talk about histotripsy now, and I gave you all the data about what the other options can accomplish in terms of survival. Histotripsy, because it’s a new method, and we’ve only been doing it for one year in the United States and in the world, we know we won’t have five year survival data. But how does it work? So first, it’s a non- invasive tumor treatment. It does not require surgery, it does not require a needle to be inserted into the liver. It’s just ultrasound, so in that regard, it’s very novel. It could be compared to external radiation therapy. But external radiation therapy is a lot more toxic. So, what it does is the ultrasound, the shock waves from the ultrasound, induces cavitation, that is, bubbles that expand and collapse so rapidly that it destroys the tissue and the cells, and makes them explode. It’s like an implosion. And that area that is being destroyed turns into what we call a lysate or a liquid, a liquid that only has proteins or different components of the cells, but has no viable cells. Now, the important thing is that these cells that are being mechanically disrupted are cells that are usually either cells like liver cells or tumor cells, but some cells that make blood vessels or bile ducts or scaffolding structures of the liver are not being destroyed because they have high collagen, so that allows the liver to regenerate back in that area. Once that lysate or that fluid is being reabsorbed by the lymphatic system of the liver, the liver will eventually regenerate in that area. This is a little video that you probably saw. But just to give you an idea, how the setup is for histotripsy: We do histotripsy in the intervention radiology suite. Some other centers to it in the operating room, some other centers are doing it in an intervention room that is not specific to anything, but we need to have the patient under general anesthesia. That’s important to understand. So you know patients that have severe heart disease or severe lung disease, some diseases that are not related to the cancer, but you know that they are unsafe for general anesthesia. Those patients cannot qualify for it. But we would put the patient under general anesthesia, and then we use a special water bath that has to be put over the the abdomen in the region of the liver to be able to transmit the ultrasound waves into into the liver. And we use a regular image in ultrasound that is coupled to it so we can see the lesions.

Dr. Juan Rocca 49:05
So this is how the device looks. This is pretty much how we set it up. And then this is a closer view of what happens inside the liver. If this is the tumor, these shock waves start creating these bubbles of implosion and expulsion, and with that, start destroying the cells and creates a bigger bubble. It’s like a chain reaction. And that bigger bubble starts going around. We usually have a very focal targeting of the beam, and we move it in around the the size of a golf ball, if you want, until we create that size. Here you can see what happens when you have this fluid or the lysate. The blood vessels are usually preserved and the lymphatics are usually preserved. So that would allow the liver to regenerate in the coming weeks after the destruction of the tissue.

Dr. Juan Rocca 50:23
This is a representation of once the lymphatic system absorbs the tissue-the lysate, the liver tissue, can grow back into the area. Let’s look at the difference between histotripsy and ablation, because they in some regards are comparable, because histotripsy can be used for lesions that are about three centimeters or less in order to treat the entire lesion. The difference between ablation and histotripsy is that, because ablation pretty much hits the area and cooks the tumor cells on the liver tissue, the regeneration of the liver is not as much. It takes a long time to reabsorb the tissue because it’s pretty much not liquid, it’s solid and it’s is like a burnt tissue instead. You can see the defect there. Here, that beginning is very similar to ablation. But then over time, the normal liver tissue starts growing already, until you have a minimal scar there. So this is one aspect of histotripsy. The other one is that there’re some areas that we can preserve blood vessels and bile ducts after doing histotripsy in areas of the liver.

Dr. Juan Rocca 51:50
The final one that maybe many of you have heard is what we call the abscopal effect, which is an effect that by treating one or two lesions, and by allowing the liver to reabsorb that lysate, with antigens of the tumor that unmasked for the immune system tumor antigens, and allows the immune system to be more active against other tumors that were not treated. That’s a very exciting, exciting effect. However, we don’t see it too often. We see it in about 20% of the cases. And we still don’t have a good way to take which cases are going to have that effect and which cases are not. It’s kind of a hit or miss. But I think it’s important to remark that this is another potential benefit, and I think with more data, we may be able to determine which type of tumors or which type of genetic mutations or what type of liver or location or size can really respond with this immunologic synergistic effect. This is another example of what we do prior to liver transplant for other disease, which is hepatocellular cancer, but hepatocellular cancer is a tumor from liverdisease that we transplant. But many times before transplant, we have to do different treatments of the tumor to keep it at bay. And these are very sick patients, and we are being able to do this treatment now, instead of doing invasive treatments like ablation. We can do histotripsy to reduce the tumors or even knock out that tumor until the patient gets into transplant.

Dr. Juan Rocca 53:41
I just wanted to remark the abscopal effect is a systemic immune response that is triggered by the tumor destruction, and it can expose the tumor antigens and that can potentially enhance the immune surveillance. Now this is observed not very frequently, but it’s something that is under investigation, and hopefully we can find a way to make it happen more often. We believe that keeping chemotherapy and immunotherapy while doing histotripsy, can really help synergize the effect of histotripsy. This is just to show you how in one year only, historipsy was embraced by many centers in early state, a total of 28 centers now have it, many here in New York. And this is the number of tumors that were treated in 2024. You can see that colorectal cancer is the majority of them, about 260 cases, neuroendocrine tumors, pancreatic cancer, cholangiocarcinoma. These are all metatsteses in the liver. Cholangiocarcinoma, HCC, which is a primary tumor of the liver, that we do transplants for and other types of tumors. The specialties that do this can be interventional radiology, in some centers radiation oncology does it as well, hepatology or surgery. There are different trials that led to the approval of this technology for treatment of liver tumors. Some initial trials a few years back. – But the trials that really led to the FDA approval was this Hope4Liver trial, which is a multicenter trial in the US and Europe that was able to demonstrate effective treatment once you target and you can go around the tumor and destroy the tumor and the tissue around it. That’s the effectiveness. It didn’t come back within 30 days, which is not long term, but at least within 30 days, and then that it is safe. That there were only a few adverse effects because it’s non- invasive. There were minimal cases of serious adverse events that we call, like infection, like liver failure or death. In those 44 there were a total of three cases only.

Dr. Juan Rocca 54:00
Now this is the important study, the BOOMBOX trial. The BOOMBOX trial is a prospective trial, where we enroll all the patients that are receiving histotripsy, and we follow them up for five years. This is why it’s so important, because we really need to get the five year data to be able to compare to all the existing tools that we have to treat liver tumors. We are participating in this study where we actually enrolled three patients already. And I think it’s it’s important that if you are the receiving histotripsy, you’re very likely going to be enrolled in the BOOMBOX trial, or you may be even enrolled in some other specific trials that are using historipsy in different contexts. For example, in the contexts of certain chemotherapy, certain immunotherapy, or associated to other treatments.

Dr. Juan Rocca 57:21
I have a clinical case that is a transplant case. Just wanted to highlight that there was a woman that had a diagnosis in 2020 and had surgery for the colon in 2021 January, and then had liver metastases and a year later had surgery in the liver in 2022 where they removed different lesions, they removed seven lesions. Okay, so there was resectable, but in the high risk end, and had ablations, then had chemo later, and then five months later, as soon as they stopped the chemo, there were some tumors that came back, they recurred. So she had another surgery in January of 2023 one year later, with resection of three lesions and ablation again, and then was followed by chemotherapy again. And so this is a colorectal cancer operated in 2021 liver surgery. In 2022 liver surgery in 2023, and every time that they stopped the chemotherapy, the tumors were coming back into the liver. The patient was sent to us to discuss different options of treatments. She had no mutations that were of concern for us. And then I just want to show you a little bit, at the top of presentation, the tumors that were active. There was one here, one here, one here, and another here, four liver tumors, and there was an area that was also non-viable of liver. So we did a first intake. We did a PET scan that showed us that the the metabolic volume of the tumors were not that big. A metabolic tumor of almost 90. Best survival is 70 or less, but 90 is quite acceptable. You can see here, 1-2-3-4- 4 tumors, and there was a question of a fifth tumor. In this case, we could say that there’s enough liver. And there are only four tumors, why don’t we go back and resect it again? Yes, but this is when the concept of biology and resectability can come together. Anytime you stop the chemotherapy after resection, the tumor came back, and it was the third recurrence. So, we were a bit skeptical about doing again a resection, and we presented this case at the tumor board. We looked everywhere, the chest, the the bones, and there was no evidence of disease anywhere else. So we presented this as different treatment options. One was to start the chemotherapy of course, to repeat resection and ablation. We could refer her to another center. -We don’t do the hepatic arterial infusion pump, but she could go to receive hepatic arterial push pump, then resection. The problem here was she already had multiple resections. We could include her on the transplant pathway. And so we reinitiated the chemotherapy. And then after three months later, after chemotherapy, she got stable disease, we decided to do a periportal lymphadenectomy to make sure that the lymph nodes around the liver were negative. These were negative, and then we continued again, chemotherapy for another three months, while we gave Y-90 to keep the tumors at bay,after stopping the chemotherapy. And we were able to restage again, we didn’t see any evidence of disease outside the liver. Disease in the liver was better. There was less tumor burden. Here you can see the lymphadenectomy. So after we did a final run of patient, and we find that it was controled liver disease with those four lesions that were smaller, the tumor volume on the PET scan went from 90 to 64, under 70, we considered that she was a good candidate for liver transplantation, and we were able to give a live donor liver transfer from her son. That was in May, and so far, at this point, she has no evidence of disease. So I think this can illustrate all the different therapies that we talk about, except for histotripsy for this case. But we would consider histotripsy in some cases that are going to transplantation, to show you that we always need to find a way to either make someone resectable, or someone that can have aggressive treatments like ablation, like a hepatic artery infusion pump, to see if they can respond and they can become resectable, or they can become transplantable and ultimately prolong the survival more than 50% at five years which is evolved. I’m going to open the floor for questions.

Betsy Post 1:03:16
Thank you so much. I’ve learned a lot. This was great. I think it really talks to all the different treatments and how they can be used together. And a great introduction on histotripsy. I know we appreciate it. So I’m gonna go through some of the questions, we have a question on transplant. Is it always best to have a transplant if one is a candidate for that and not resectable. So I think, sort of looking at that pathway.

Dr. Juan Rocca 1:03:45
I think it’s worth to have an early consultation if the diagnosis is unresectable and no evidence of disease outside the liver, I think it’s worth it to have a consultation. Remember, anytime you go to a transplant center to inquire about transplantation for this, they will put you on a protocol that will require at least one year of wait time from the time you get a diagnosis, and maybe six months after removing the colon and having chemo for about a year, at the very least, to show that you have stable disease. And then we do all this testing to make sure that there’s no disease outside the liver. Many centers do this surgery before the transplant to remove the lymph nodes to make sure that there’s no lymph nodes that are positive around the liver. So it really is a process. So if there is any question about eligibility for transplant, I think it’s important to go to a transplant center that has a protocol for that and inquire.

Betsy Post 1:04:56
We have a question about general anesthesia. So I think it’s obvious that a transplant liver resection are going to be done under general anesthesia. But I think as far as histotripsy, Y-90, the ablation, SBRT, some of those treatments, does a patient have to be under general anesthesia, or how would you handle that?

Dr. Juan Rocca 1:05:15
Yeah, that’s a great question. Any surgical procedure, of course, is under general anesthesia. Ablation – it depends on the center for percutaneous ablation. Some centers do it with sedation only, depending on the location. Some centers prefer to do it with anesthesia because they have a better control on the movements of the patient. With histotripsy it’s the same thing. Histotripsy requires anesthesia because when you target the lesion and you treat it, the respiratory movement has to be predictable. So with anesthesia, we can control the movement of the of lungs and how the liver moves, and we can decrease the amplitude of the movement to the minimum to try to stay in the area and not burn. For example, when we’re doing it, histotripsy or ablation, but mostly with histotripsy we don’t want that area to move too much, because maybe then the ultrasound beam can go into the colon or to the stomach or to the duodenum, to areas that are not liver, and can damage those areas. So that’s why it requires general anesthesia. Now, if we find a way to do a less invasive treatment, like with ventilation that doesn’t require general anthesthesia, that’s in discussion. But so far to my knowledge, none of the centers that do histotripsy are avoiding general anesthesia. Everyone is using general anesthesia so far. For radioembolization you might not need general anesthesia. That’s sedation only. For radiation, you don’t need anything.

Betsy Post 1:07:14
Is it logical to pursue partial histotripsy with the intent of down staging before other therapies such as SBRT or Y-90? In other words, is it logical to target one part of a tumor with histotripsy and then use another therapy to finish the areas that were not treated? For example, in cases where Y-90 or SBRT would not get all of the tumor alone or would be too risky?

Dr. Juan Rocca 1:07:42
Yes. So that’s a very important question, and this highlights the role of multimodal treatments, right? Yes, histotripsy can be done for what we call complete treatment or partial treatment. So if histotripsy can be done, let’s say, the liver has three tumors. The three tumors are under three centimeters, and they’re in spots that are safe to burn around the tumor or burn. Just do the histotripsy to lysate the tissues, so that will be a complete treatment. There were three lesions, the three lesions were completely treated with the histotripsy. That’s a complete treatment. Okay. Now, for most of the cases, we do histotripsy in situations that we have more tumor burden, multiple lesions, different sizes. And what we do is we try to do a stage histotripsy. We treat two or three tumors at a time. And sometimes, for example, if there’s a tumor that is five centimeters, we may treat three centimeters once, and then come back and treat the remainder two centimeters and to try to clear the entire tumor. Or sometimes we have multiple tumors. Some of them, we can target them with histotripsy, but some others may be in a difficult location for histotripsy, either because it’s close to the colon, close to the stomach, or high up, or surrounded by lung, and it’s hard to get the ultrasound beam to get there. So sometimes we use combined modalities of histotripsy with ablation or histotripsy with radiemobilization in order to treat all the tumors that are in the liver.

Betsy Post 1:09:39
Thank you. Could you provide your thoughts on getting a hepatic pump with replaced right hepatic artery abnormality?

Dr. Juan Rocca 1:09:50
Yeah, so the the arterial anatomy is an issue, and the eligibility of the hepatic infusion pump depends on different variations. But the problem would be, when you’re trying to inject, the catheter of the pump has to be in an artery that’s only to the liver and not anywhere else. So many times when you do this procedure, I don’t do this procedure, but Memorial Sloan is located across the street. They do it, and so they are very detailed about the different branches of the arteries where the catheter is to make sure that that chemotherapy goes only into the liver and doesn’t go into the stomach or into the pancreas, into the duodenum. Many times, when you have a right replaced hepatic artery it may be very difficult to control the flow, or can even reflux. And that could be a contraindication. That’s right. So if you were turned down because of having a right replaced hepatic artery, this could be a contraindication, yes.

Betsy Post 1:11:11
For tumors that are under three centimeters, is radiation equally as effective as ablation? I think you talked a little bit to that, but I did want to ask you that.

Dr. Juan Rocca 1:11:23
Yes. So this is the COLLISION study. The study that I showed was a multi center study in Europe. The research came out with the final results. Actually, the study was stopped earlier. So the study was designed as a non inferiority trial. This is the gold standard, was resection for tumors less than three centimeters. And they started comparing ablation for those same tumors, same size, and they couldn’t see any significant difference. They recruited 300 patients, 150 and 150, pretty much. And they stopped it early because there was no difference in the outcome. So this validates ablation as an equal treatment to resection for tumors under three centimeters. Of course, the devil is in the details, and that doesn’t mean that in your specific case, you should have an ablation, another resection. That depends on the location of the tumor. Sometimes the access with the ablation, sometimes we do it with surgery, but sometimes percutaneously, it’s not as easy to access every tumor in the liver than with a surgical ablation, or sometimes a resection makes more sense. No, that depends on the specifics of the case.

Betsy Post 1:12:49
Thank you. And this is from a patient that actually had the histotripsy procedure done to three lesions in the liver. The patients had two CT scans since the histotripsy, and is just wondering, other than comparing the size of tumors of those treated lesions on the CT scans, how would the patient know if histotripsy-induced abscopal effect has taken place?

Dr. Juan Rocca 1:13:17
Yeah, so far the way to tell is with imaging. This could be MRI or a CT scan that has contrast. And with that between two to four weeks after the procedure, you could see the abscopal effect is, if you got treated three tumors, but there are three tumors that were not treated. You should see a rim enhancement in the tumors that were not treated, like there’s some inflammatory activity around the tumors. If you do it early, maybe two weeks later, and if you do it later, like four weeks later, if that already happened, you should see a reduction in the size of the non-treated tumors. The only way to document abscopal effects nowadays is, like we did mention so far.

Betsy Post 1:14:13
Can you comment on the HAI pump for patients after resection to help prevent recurrence, so, when a patient would get a pump to help prevent recurrence. I think you did comment some on that, but I just wanted to ask that.

Dr. Juan Rocca 1:14:27
So the pump has benefits. It’s an aggressive therapy. It’s like two stage hepatectomy or even liver transplantation. These are aggressive therapies, and it has benefits, but also has some drawbacks or toxicities. The benefit is if you respond to the pump and you can downstage the tumors to make them resectable, which 50% can respond? Good news. You’re in a good spot if you respond and you can have resection. For example, the chances of recurrence is a lot less after using the hepatic arterial infusion pump. So not only it can reduce the burden of disease and make it resectable, but also it will prolong the amount of the recurrence-free survival. Okay, so that’s important. On the other hand, sustained treatment with the pump can lead to liver toxicity, and in some cases, can lead to some irreversible liver damage on the bile ducts. It is reported to be 1 to 3% but when it happens, it’s a real deal. So as part of an aggressive treatment that can be very effective, it’s always important to discuss the potential risks of having liver injury or having to interrupt the treatment because there’s liver toxicity. Not every patient can continue the treatment, and sometimes it has to be interrupted. The management of the pumps requires a multidisciplinary team that is not only the surgeon, but it’s very specific oncologists that know how to manage the dosing in order to manage the toxicity in the liver and to try to mitigate the potential injuries to the liver.

Betsy Post 1:16:36
In your opinion, how many times can you perform resection and targeted therapies on the liver before you would consider that transplant path would be the best path forward.

Dr. Juan Rocca 1:16:49
Yes, well, the clinical example I showed you was two times resected, and the third time that it recurred, we decided to do a liver transplant. It depends on the presentation. If someone presents with unresectable disease, but in that gray zone that is unresectable, but the size of the tumor is no more than five centimeters, there can be multiple tumors. The metabolic volume on the PET scan is not high. It’s not more than 90. Of course, that kind of patient has to be on chemotherapy. So if they are stable on chemotherapy, or responding on chemotherapy, and we see that there are more than six seven lesions, it could be considered for trouble, because we know that resecting six or seven lesions with surgery, the chances of recurrence is very high. And the long term survivors are showing one of the curves, of resection, chemotherapy, of seven or more lesions, the five year survival is about 25%. So some cases that present like they could be considered for transplant from the get-go based on how they present, in the number of lesions, the number and the type of mutations we would consider transplantation up front. But clearly resectable cases with low risk of recurrence, or a lower risk for recurrence, we would resect first.

Betsy Post 1:18:38
Does Weill Cornell have different criteria for transplant than Columbia?

Dr. Juan Rocca 1:18:45
Not too different. But Columbia just started doing this. I think that they just listed a patient so they’re trying to use the more recent criteria from the transplant trial. We have our own criteria. Our trial has been around since 2021, and we evaluated 35 patients. We transplanted five. So we actually work together. We are under New York Presbyterian we are two different universities, or two different types of faculty under the same hospital system. We work on two protocols together, and we are actually working on a common protocol based on our experience with transplantation and their experience.

Betsy Post 1:19:39
Does the liver regenerate in areas where you receive Y-90?

Dr. Juan Rocca 1:19:44
Not so much. No. The areas that were not affected by Y-90 will regenerate. But the liver areas that receive Y-90 will not. It depends on the doses of Y-90. They are very variable. It depends on some mapping studies to make sure there’s no — dosage chance into the lungs, depending the goal of the of the Y-90 if it is to destroy a specific area of the liver or to give lobar Y-90 like before transplant, to kind of keep the tumor at bay. But lobar Y-90 is very toxic too. So sometimes, if we give the lobar Y-90 too early before transplant, we may have some liver failure. So I think it’s important to understand, at the timing of the transplant, if you have a live donor, it’s a lot easier to really have a good timing and be able to to schedule the Y-90 3 months before transplant, knowing that at that time, if the liver has failure, it can be rescued with a transplant. When you go into the disease donor wait-list, and it’s more unpredictable when the transplant is going to happen so that we can run into liver decompensation or liver failure from the lobar Y-90 that was already beaten up by the chemotherapy too and prior resections, etc.

Betsy Post 1:21:15
Is histotripsy an option for patients with the BRAF mutation, and then, as well, a RAS mutation, such as NRAS or KRAS?

Dr. Juan Rocca 1:21:25
Yes, there’s no contraindication based on mutations for histotripsy. The limitations on histotripsy are certain size of tumors or certain locations where, we may not be able to clean the entire tumor from the liver. But if there’s no other therapy available,I think histotripsy is totally indicated, yeah.

Betsy Post 1:21:55
I just want to make sure.

Dr. Juan Rocca 1:21:56
We do histotripsy in patients that we would not be doing any other therapy because they have disease. We know that the liver disease is the one that really dictates survival. Many patients that present to us with liver metastases, but they have lung metastases, bone metastases, and they are generally doing well, and the liver disease is threatening their survival we do histotripsy on those patients.

Betsy Post 1:22:30
Is it possible if you have a tumor right next to the IVC?

Dr. Juan Rocca 1:22:35
With what technique?

Betsy Post 1:22:37
With histotripsy, sorry.

Dr. Juan Rocca 1:22:39
Yes, yes, the IVC is a big vessel, same as the hepatic veins. We usually anticoagulate for that, because even if the vessel is preserved, the skeleton of the vessel is preserved at the endothelium, which is the the cellular lining that is very delicate on the blood vessels. That one gets destroyed, but the structure remains. So the endothelial lining gets repopulated very quickly. But to prevent clotting, we give anticoagulation. So for the hepatic veins and the IVC, the venacava, it is safe to do it with anticoagulation. For the portal vein,t hough, it’s a bit trickier because the portal vein is a different type of flow. Sometimes despite anticoagulation, we can have clotting on the portal vein. And that’s something you have to be careful about. So lesions are very close to the center of the liver, where there’s a lot of portal branches, we try to avoid them.

Betsy Post 1:23:55
And I apologize if I missed this one. We just have a couple questions left. One is, what is the largest size that can be treated with histotripsy?

Dr. Juan Rocca 1:24:05
In different sessions, you can treat larger lesions. It all depends on the location. And sometimes large lesions, you may be able to access with the ultrasound being an area of the lesion, but the other area is too high, there’s too much lung that doesn’t let you deliver energy. But by six centimeter lesion, if there’s no other good option to treat it, I would try histotripsy. Now we should consider, usually, for lesions that size, we also consider Y-90 because Y-90 is very effective at reducing large size lesions if they are not resectable.

Betsy Post 1:24:47
Let’s see. I think all the liver-related questions are pretty good. I think we’ve got some people saying they’re going to make an appointment with you. I think you had your email on that prior slide, that last slide, so I just want to make sure that as part of the recording, everyone can see that. So if you do have questions specific to your case especially, and you want to seek a consult, this is the email with follow up questions, I feel like we got everything we could.

Dr. Juan Rocca 1:25:25
I’m not very reliable with emails. Some days I’m in the operating room all day, and I get many patients that send me emails. I think it’s probably better to leave an office number, because at least someone can be more accountable for replying, but yes, I can send the office number, and we have a free assistant that usually take all the calls.

Betsy Post 1:25:55
Perfect. If you send that to me, I’ll make sure that everyone gets it. And I appreciate that. I appreciate all of your time. You’ve spent an hour and a half with us tonight, late in the evening, and we are so appreciative. I learned a lot. This was great. I know that the patients and families here tonight got a lot out of this, and I just can’t thank you enough. So thank you so much, and there’s a lot of thank yous in the chat.

In this video, Dr. Ryan J. Ellis & Dr. Anita Turk delve into HAI Physician & Patient Panel. Recorded in March 2025.

Betsy Post 00:00
Welcome everyone, to tonight’s DocTalk. I am really excited about this one. I love all of our talks that we get to do, but this one, I think, is really special because we have a physician-patient panel. I think this is probably the first time I’ve done one of these. We get to hear from our expert physicians as well as our very experienced patients with their first-hand knowledge of HAI therapy for colorectal cancer liver mets. I’m going to have Keith help me to advance to the next slide. I’m going to do a few introductions and tell you how this is going to work, and then we will get started. This evening we’re very pleased and honored to have a medical oncologist from Indiana University, Dr. Anita Turk. She has a lot of experience with HAI from the medical oncology standpoint so she’s here to help us in that regard. And then we have one of her colleagues, Dr. Ryan Ellis, also from Indiana, and he is a surgical oncologist with of course, experience placing the pump, including in a robotic fashion, which I think is really interesting as well. And then, of course, for our patients, I’m going to go ahead and introduce our patients: we have one that I think hasn’t made it yet, but we’re going to go on without her, and hopefully she can join us. But we have Hope Brooks, and I think if you are a member of COLONTOWN, I think it’s okay for me to say that you probably know Hope. She received her HAI pump back in 2022 and we’re going to hear a lot from her tonight, about her experience with the pump. And then Michael Riehle, who received his HAI pump back in 2020. I think it’s really important to know that the pump helped him so much that he was actually able to have his pump removed in 2023, so he’s long-time disease free and had his pump removed. He can even speak to that from the very beginning to the end, truly. And then hopefully Megan will be able to hop on. She received her pump in 2022 and she is also a longer term NED patient as well, so hopefully she’ll be able to join us. Before we get to the next slide I wanted to tell you how this is going to work. This evening, we have a fireside chat-type of setup: I have a lot of questions for our panelists, I’m going to ask those questions, and then please put your questions in the chat or Q and A. You should see a button that will say either “Chat” or “Q and A”. Keith is here. He’s helping run the tech this evening. He can answer any questions that you have about that. You can send him a message and he’ll be happy to help. At the end, we will take those questions that you put in the chat or Q and A feature. So with that, I’m going to turn it over to Dr. Turk. She’s going to set us up with some slides and some knowledge of HAI and then we’re going to resume our Q and A.

Dr. Anita Turk 03:00
Thanks Betsy and hello everyone joining us today. Appreciate you all logging on, and those who may be joining us later, appreciate your time. So as Betsy said, I’m a medical oncologist. I specialize in taking care of patients, especially with advanced colorectal cancer, and we are a main site in the State of Indiana to provide hepatic arterial infusion pump therapy. So what does that exactly mean? Many patients have a port that allows them to get chemotherapy conveniently throughout the body; Patients have to wear 5-FU pumps over 48 hours – this is is very similar. How it’s different is that it’s placed in the abdomen instead of the chest, and instead of going into a vein, it’s actually going into an artery, specificly the hepatic artery, or the liver artery, which is one of the blood vessels that supplies blood to the tumors, as well as the liver. What’s unique about the liver is that you actually have two types of blood flow. You have ‘portal vein’ and you also have ‘hepatic artery’. Your normal liver actually requires mostly the portal vein for blood flow, whereas the hepatic artery will differentially supply the tumors inside the liver and that’s how we are able to take advantage of this therapy. When we deliver the drugs, specically Floxuridine-it’s a very, very potent form of 5-FU, and we’re able to do that directly in the liver for a couple of reasons. One, because of its unique anatomy, with two sources of blood flow. We’re able to try to target the cancer cells over the normal liver as much as possible. And number two, only a small amount of the drug is actually exposed to the rest of your body, so the fancy terminology for that is called, “first pass pharmacokinetics”. Essentially, what happens is that medication is taken up by the liver, is affecting the cancer cells, but the normal liver is then able to metabolize the chemotherapy into a benign substance that’s not harmful. So as it’s spreading through the rest of the body, you’re not getting effects like nausea, vomiting, diarrhea or low blood counts, and that’s why patients are largely able to tolerate this therapy pretty well. (Keith, you can do the next slide. …Oh yeah, we can play the sample. ) (Video begins to play on screen.) So I think what this video is essentially showing is that the chemotherapy goes directly into the hepatic artery, and because of that special blood flow I talked about, the chemotherapy is being exposed more to the cancer cells than it is to the regular liver. So the pump that’s currently approved right now is the Intera 3000 Hepatic Arterial Infusion Pump. It’s about the size of a hockey puck, fts in the size of your hand. And basically how it works is that there’s a chamber of gas that expands at body temperature, that pushes the chemotherapy into the body at a certain rate, usually about one or 1.4 CC’s per day so it’s kind of going through the liver continuously. You don’t need to worry about it. You can continue your regular activities. The pump does have to be filled every two weeks when it’s actively being used and the rate is very sensitive to altitude and heat changes. So if patients have a fever, or, if a patient steps in the sauna for too long, that is going to affect the rate. So we always like to counsel our patient about those things so we can take that into account when they’re doing their doses of chemotherapy. So generally, how this works is if a patient is considered a candidate, you usually start with meeting a hepatic arterial infusion pump team that’s going to involve both a medical oncologist and a surgical oncologist. We review the history/where did the cancer start/where has it spread/specific parts of the biology, often involveing DNA analysis/making sure there aren’t other, better options are available on the table/and what treatments the patient has already received/and probably the most important thing, what’s the baseline liver function of that patient. We then want updated scans, whether that’s a PET scan, CT or MRI, to ensure that we’re treating a patient where at least a majority, if not all of the disease that we’re concerned about is in the liver. As I mentioned, this drug is not going to spread throughout the rest of the body and isn’t going to kill cancer cells outside of the liver. Usually a couple of weeks before the pump is placed, chemotherapy’s stopped, so your body is recovered, your blood counts are up. You’re ready to go to the the OR, and then you head to the OR with someone like Dr. Ellis. And maybe I’ll turn things over to Dr. Ellis to briefly explain the procedure and anatomical considerations for patients.

Dr. Ryan Ellis 07:40
Sure. So thanks, and again, I’ll reiterate, I appreciate everyone’s time tonight. But for the operation itself, a lot of it is dictated by exactly what the operation entails. This can include a liver resection for some patients, meaning we do some liver surgery or remove some tumors, as well as placing the pump. Or it can be the pump by itself, and within that context, there can also be open and robotic approaches. So the range of the surgical experience can be pretty wide, but overall, I would say the vast majority of patients receive some sort of open operation with or without removing any tumors from the liver. Some patients may even still have a colon tumor that needs to be removed at the time of the pump placement and then when you wake up from surgery, you would have an incision from usually about your breast bone down to your belly button, if not a little bit longer, depending on the operation. And as Dr. Turk mentioned, the hockey puck is underneath the skin, usually on the left side of the belly. You recover from surgery, hopefully relatively quickly. And we can, maybe later in the talk, go through some of the real details of what can happen with this operation, both immediately after the operation and later down the line and during your hospital stay, we get a special scan that is among the most important studies in this entire pathway, where we verify that any medication that we put inside of the pump go to the liver, and only to the liver. The surgery involves essentially me, reconfiguring the arterial system to the liver so that any chemotherapy that goes in does not go to other places. Places like the stomach or the pancreas, because those parts of the body are not going to tolerate the level of chemotherapy that we’re delivering. So once we get that study done in the hospital and you’ve recovered and are eating and moving around and taking great care of yourself, then we send you out, and usually about two weeks later, or I should say, exactly two weeks after we put the pump, you come back to the office and see the team again and start talking with Dr. Turk about putting some medications in the pump.

Dr. Anita Turk 09:59
Thanks Dr. Ellis. Yeah, the two weeks after that pump was last filled, it is really important that the patient’s able to come back to be seen to have that pump filled. These pumps do need to be filled every two weeks. We don’t want them getting emptied and dry, because that puts the pump at risk for developing a blood clot and then making it difficult to use again in the future. Typically at that first visit, depending on how the patient’s doing and liver function tests are doing, if the patient’s doing very well, we can even start chemotherapy right away. But regardless of when you start, you’re coming in every two weeks for a pump fill, alternating between chemotherapy and then a two week break with heparin and so on and so forth. Most physicians recommend doing this course for about six months of treatment, so that’d be six rounds of floxuridine. Now, depending on the clinical scenario, that can be pretty variable: Patients are doing really well, the liver is doing fine,some patients may have a longer course. If they have a complication, some patients may have a shorter course. As we’ll get into this, there are some risks and complications from the chemotherapy itself with specific implications on the liver. Fortunately, things have gotten a little bit easier. Patients come from all over and may not be close to a tertiary cancer center where they have easy access to this pump therapy. Now there are nursing agencies that are able to do these pump fills at home, which makes it a lot easier for patients to get this type of treatment when they live hours and hours away where coming in every two weeks can be challenging, and we have increasing experience using these teams that come to your home at Indiana University. I know other institutions are doing it as well. Some patients may actually be on systemic chemotherapy at the same time, and again, depending on what the need is for that patient. Once the course of that hepatic arterial infusion pump is done, whether that’s six to eight months, again, depending on that clinical scenario, chemotherapy can be restarted if needed, kind of the routine, whether it was FOLFOX, FOLFIRI, a targeted agent, depending on, again, the biology or what’s going on with the patient. And then we follow the patient, whether that’s on or off chemotherapy, and monitor the liver closely. We have many patients that the liver will be in good shape, no active disease for a long period of time. In very rare scenarios, but it certainly does happen, you’re going to hear about today, there are people who have complete responses to the pump therapy where we can stop all the chemotherapy altogether, but this pump therapy can be repeated. So again, you’ll hear from one of our patients, even when we do one course, we do not remove that pump right away. We often keep it in for several years to ensure that the patient’s disease is stable or clear. And if the unfortunate situation does happen that the cancer does start growing again, we can always use that again. And again, knowing that important relationship that you’re going to have with your arterial infusion pump team is really important. So making sure you have good communication and contact with your tertiary care center is really important when you’re considering this type of therapy. So, how are we using it for patients with metastatic colorectal cancer? Specifically when we think about this in our patients, it’s when it cannot be surgically removed. The gold standard, if you are unfortunately, a patient that has metastatic colon cancer to the liver that can be surgically removed, that’s still the standard of care. But for patients where that’s not an option because disease is on both sides of the liver or for some other anatomic reason can’t be removed, this is an option we can certainly consider for patients. There is data that shows that this can potentially prolong survival, but it certainly improves outcomes within the liver for patients that don’t have resectable disease, that’s one area where we use it. We particularly use it, the data supports using it after patients have had some round of chemotherapy and that’s no longer working in what we call that second or even third-line space, where the current standard options aren’t working, the cancer is growing in the liver, and we need to be more aggressive. The other common indication for this is patients who are very high risk that did have a surgery and had the cancer removed from their liver, but we’re really worried about it coming back and we’re concerned there’s probably microscopic cancer cells left behind where we will use the pump after surgery to try to kill any cancer cells that may be in the liver that are left behind. There’s data showing that that helps, again, with liver outcomes and can potentially improve survival in addition to chemotherapy. Those are the two big areas where we use it right now. There is an ongoing clinical trial called EA2222, or The Pump Study, and we are one of those sites, and it is open at most hepatic arterial infusion consortium sites actually trying to answer the question, “Can we use this in the first line setting when a patient first walks in the door, gets chemotherapy, they’re doing okay, liver function’s good. Can we add the pump in and help improve outcomes?” And that will be a really important trial to see, is this pump going to be helpful for patients earlier in their course of treatment? So in terms of safety information the pump is only really authorized to be used for Floxuridine, Heparin, and then we even use Glycerin for it. Glycerin is just a really thick solution to slow down the pump. So in that period when a patient is not using their pump, where we’re in the monitoring zone, so they don’t have to come in every two weeks, then you can really can really space out their fills to every three, even four months. We don’t use this pump for anything else, at least at this time. The pump is not considered for patients who have a lot of disease outside of the liver. Again, when you have cancer, if unfortunately, a patient has bone involvement, lung involvement, that Floxuridine and chemotherapy is not going to get there, so those patients generally aren’t considered candidates. I will hand off side effects of the pump placement itself to Dr. Ellis.

Dr. Ryan Ellis 16:14
So the pump placement, I break the problems that we can have sort of in the perioperative period into two groups. There’s what’s called pump pocket complications, which if you think of a port, essentially its the same thing, a little bit bigger. And then there are intra-abdominal complications. The pump pocket complications are primarily related to fluidaccumulating within the pump. We have things called a seroma, which is a benign fluid, almost like water, that can accumulate on the inside. It can make it a little bit problematic to access the pump. You can imagine, if the pump is floating in a bubble of fluid, it’s hard to find with a needle after that, but that is not a particularly dangerous complication. In the same areas is hematomas– a little bit of bleeding around your pump immediately after surgery creates essentially a blood clot around it that can also cause some trouble. And then the third thing we worry about that happens is infections. It is hardware, it is not a natural substance to have under your skin. The rate of all that is, overall, quite low– infections, in the low, single digits. But all those things can happen. Regarding the issues that we canhave inside of the belly the most obvious one is some bleeding. This is essentially a vascular surgery operation that happens on the liver, so there is a small risk of bleeding around the pump insertion site within the arterial system, after surgery. And related to that are development of things called aneurysms, which usually occur at the site where the catheter enters the arterial system. Those are the bigger issues that we can have with the pump. Of course, if anybody has any more specific questions, we can talk about it later, but those are the ones to really consider when you’re when you’re thinking about having one of these placed.

Betsy Post 18:27
All right, so here we are at the Q and A. I’m going to turn my video back on, hopefully my internet’s going to cooperate. It did say that it was unstable, so if I go off camera, it’s just because of that. We’re going to kick off the Q and A and I’m going to start with a question for our doctors. Thank you for that awesome introduction. I think maybe we’ll just get a little bit more specific. On deciding to get HAI therapy, I know you talked a little bit about extra hepatic disease and maybe some of those limitations, but I’d love to know a little bit about who is generally a candidate for HAI. So, who might be a candidate, that’s the first question. And then it’s a two-prong question, because the other half of that is, what are some of the other factors that patients should consider when they’re considering a pump?

Dr. Anita Turk 19:20
Absolutely. With the data that we have, patients that seem to benefit from this therapy are patients that have liver-onlymetastases, meaning the cancer has only spread to the liver, and ideally, the original tumor is out. There are some small exceptions to that rule, as there is it to anything in medicine. I certainly myself, have patients where they have one little,tiny lung nodule, or two nodules where they may or may not be cancer, where we’ll certainly sometimes make some exceptions if a majority of the cancer is in the liver, knowing that that’s going to be the issue if the cancer grows, that liver failure is going to be the issue that will unfortunately take that person’s life. So those are generally the people that we think about. The data strongly supports it in that second and third line setting, meaning you kind of had your standard of care chemotherapy with some biologic agent, whether that’s Avastin or bevacizumab or Vectibix or panitumumab, and that patient’s now progressing in the liver. What are next steps? I often include a pump chemotherapy through the hepatic arterial infusion pump. There are some anatomic considerations as well in terms of blood flow to the liver. I’ll hand that off to Dr. Ellis – what he looks for on the CT scan.

Dr. Ryan Ellis 20:39
Right. So I vaguely alluded to this, essentially a vascular exclusion of the liver because most fundamentally, when we put this pump in that floxuridine can’t be traveling throughout the rest of the body. It can’t be going into the stomach or the pancreas or the small intestine. So for simplicity sake, the the majority of patients have the arteries going into the liver shaped like a “y”. Now that’s not a vast majority. It’s a little bit more than 50% of patients have what we call standard anatomy, and the other 40-some % have a combination of blood vessels that is usually accommodating of a hepatic artery infusion pump, and in rare cases, actually can make inserting the pump anatomically impossible. The classic example of that would be, if there’s only one blood vessel feeding the liver, I would not have a place to essentially tie that blood vessel off to insert the catheter without also cutting off all the blood flow to the liver. So I have to take advantage of what I would say is relatively normal anatomy. That’s an exception, but I will say periodically, we will review patients who are otherwise biological candidates that anatomically cannot accommodate having the pump placed.

Dr. Anita Turk 22:05
Now, getting to that second part of your question, — (speech interrupted with a brief interjection from Betsy Post)

Betsy Post 22:09
— I just wanted to say, (Didn’t realize that Dr. Turk had started speaking due to connection lag.) — go ahead. I’m sorry. We have, oh, sorry about that. I thought you were finished, and I do apologize. I did want to say for anyone that came late that we do have a Q and A, so I do see five questions already in the Q and A, and we will get to those. So I just want to make sure everybody knows we see them.

Dr. Anita Turk 22:25
I was just going to get to the second part of your question. You know, when you’re evaluating a patient, of course there’s a surgical component, the cancer biology component with the medical oncologist, there’s also the patient component. Part of this does have a dedication of time in that you’re coming in for a pump fill every two weeks, and we have to staypretty close to that as possible. There is some flexibility there, because we don’t want that pump to empty so I always emphasize with patients that you need to maintain a relationship with the institution that you’re going to, if that’s far away,that’s something you really need to take into account. Again, I did allude to the nursing agencies that will help take care of these pumps at home, but that doesn’t replace going and seeing the physician, making sure that pump is operating appropriately, that your liver numbers are doing okay, and that you’re getting appropriate dosing. So as much as I’d like to say, it’s a one time visit and we could do it all at home, it’s not that simple.

Betsy Post 23:26
Thank you. Have a question for one of our patients, or both. I think that I’ll start with Hope and then Hope when you’re finished, Michael, I’d love to hear from you as well. So how did your doctor decide that you were a candidate for HAI therapy? Well, I don’t think that we have Hope’s audio, at least I don’t. Can anyone hear her? No, okay, I don’t know if you can hear us Hope, but we don’t have your audio. Well, you work on that. Maybe I’ll go to you Michael, how about you? Can you answer that and Hope work on your audio?

Michael Riehle 24:27
Sure. I know Dr Turk has spoken a lot about it being like a second and third line treatment. Mine was like a second line treatment, but it wasn’t necessarily because I was progressing with my cancer or anything. MSK wanted to try to get ahead of the ball since I was doing so well on FOLFOX and Vectibix and that my liver tumors were responding so well and decreasing so much in size, they wanted to get in there and really just get the pump in to try to get them down the rest of the way to be able to get to a liver resection. So it’s more of, just to get ahead of the game, instead of a last ditch effort for me, which was really nice.

Dr. Anita Turk 25:16
Absolutely. It’ll still be exciting to see what that clinical trial shows but in many patients, where if we really throw everything we have at the tumor, and where there’s a place where we can get to resection, that’s another special circumstance where Dr. Ellis and I would certainly consider up-front pump placement to get that patient to the OR to surgically clear the disease.

Betsy Post 25:40
Yeah, not sure if Hope has audio, so I’m just gonna see, do you have audio? I don’t hear you. So sorry. Maybe she can join on the phone. We’ll try to figure that out. Oh, I’ll say, I’m gonna ask, …okay, Keith is gonna send you a message…. We’ll try to figure this out. Michael, I’m gonna go back to you for just one other question. I know that you did live somewhere where you had to travel. And I would just like to hear what a few of your considerations may have been when you did decide to make that commitment and get the pump.

Michael Riehle 26:26
Yeah, absolutely. I live in Buffalo, New York and obviously go to Sloan Kettering, New York City, so it’s a five plus-ish hour drive something like that, or fly, and like you said it’s an every two week commitment. There’s no ifs ands or buts. You have to go, you have to go. So knowing that the HAI pump is what was one of my only options that could help me get to NED, I basically just buckled down and said, “I gotta figure this out. I gotta make this work to be able to get this pump”. Luckily, I was able to utilize a non-profit charity here in Buffalo that actually flew me for free from Buffalo to New York City. And I know that there’s a lot of places all over the country that have these organizations that fly patients for treatment. So I definitely urge a lot of people to look into air charities, to try to get themselves to treatment for this, because it’s a big cost, it’s a big time dedication. It’s really all of those things above. So really that helped me be able to commit to it and know that it was something I was gonna be able to do.

Betsy Post 27:46
Thank you.

Hope Brooks 27:56
Is my audio working? Yes. I had to get out of the meeting and get back in the meeting. I’m so sorry.

Betsy Post 28:05
That’s okay. It’s no problem. That’s why Keith’s here to help me-help you. So that’s much appreciated. Let me go ahead and ask you, because I think it’s important, how did your doctor decide you were a candidate for HAI and then what considerations did you have when you were thinking about, “Do I want to do this or not? Do I want to make this commitment?”

Hope Brooks 28:28
At my first oncologist’s office, they didn’t offer me HAI, so I found it, and I moved to a different oncologist after doing some research, and I immediately was asking for it. And when I met Dr. Chung, he said I was a perfect candidate. I had already gone through FOLFIRINOX and had a remarkable response. So my tumor was roughly 10 by 8 centimeters on my liver, and it had gone down to about 7 centimeters to one tumor from that large amount just with FOLFIRINOX and I didn’t have other disease. So he gave me a list when I first met with Dr. Chung that said these are the things we can look at, and HAI was at the top of the list. A week and a half later, I met with the surgeon, and he said the same thing, if anatomically I could accept the pump, then we talked about what it would look like to get it and how my life would be afterwards. And I was already sold on it, I think before I actually had that meeting.

Betsy Post 29:32
Okay, so we wanted to talk a little bit about the surgery to implant the pump, and my question is about what patients can expect for that surgery. But we have a question in the chat that I want to tie into that, if that’s okay. We have a patient that was asking about recovery time. I just want to make sure Dr. Ellis, when you talk about that surgical aspect, maybe talk about that recovery time, maybe robotically versus open, with or without resection, I think is important. And then one of the other questions was, when you were talking earlier about some of those complications with the surgery, a patient was asking: How would I recognize, are there symptoms of an issue after that pump placement? What can patients look out for with regard to a surgical complication with pump placement? So hopefully Dr. Ellis, you can shed some light on it?

Dr. Ryan Ellis 30:34
Yeah, sure. So I’ll start out with surgical recovery. They I’ll start with an open operation, which, is in general, a vertical incision from the belly button to the breastbone. In some cases, if you have a complex liver resection, you may have what called a hockey stick incision, where it goes down and then around to the to the right underneath the rib cage. But the difference between those two doesn’t affect recovery all that much. For an open operation, you’re usually in the hospital around four or five days, depending on the overall recovery trajectory and having any small complications after the fact. The Pump Study, the special study I was talking about, is usually done on the third day after surgery. Everything’s gone well after your operation, you’re usually eating and drinking and moving around by the time you have a pump study, and then by the time you can tolerate a diet, move around, take care of yourself and your pain is controlled with oral medications you go home, again, around four or five days after surgery, for an open operation. The robotic operation is is a little bit faster. Again, in most patients, it’s a little bit of a struggle to get a pump in robotically. Those are primarily done at more experienced centers, or especially for patients who have not had a lot of surgery before. But if that is the case, when I put a pump in minimally invasive, I actually do the pump study often the day after surgery, and those patients can generally go home, sometimes even the day after surgery, but more often, I keep them one additional day, which will tie into the complication timeline we were talking about. After any type of operation the limitations are very similar. I say for the most part, common sense. Don’t lift anything heavy to risk tearing your incisions open. Don’t go in hot tubs or swimming pools or anything like that, and risk causing your skin to break down after the operation. But thinking a little bit about complications and what you would look out for, part of my job as a surgeon, and all the surgeons’ jobs, is to keep you in the hospital to watch for the earliest possible complications that is primarily bleeding, but the vast majority of bleeding happens in the first 24 to 48 hours after surgery. The other types of complications within the pump pocket that I talked about are generally not particularlydangerous, and the things you notice is new swelling, fullness, some people even notice a sensation that their pump is floating in that fluid. And then standard times of infection, redness, a little bit of drainage from the pump pocket and things like that. There are also some longer term complications that we haven’t really discussed, which is actually once you’ve recovered from the surgery and you’ve been getting floxuridine, a percentage of patients do have toxicity from the chemotherapy to the liver. Dr. Turk, when she initiated the conversation, talked about how the hepatic artery preferentially feeds blood to tumors, which is what we take advantage of to use this for treatment. But on the other end of that, the hepatic artery also supplies blood to what are called the bile ducts. So some patients will find andagain, this is fairly rare, months and months after their treatment, they start to get a yellow tinge to their skin, to their eyes, underneath their tongue, and that can be indicative of a longer term complication. That is something called biliary sclerosis that we can come back to if there’s more interest. But for the most part, we keep you in the hospital or the duration of the scariest complications, then after that, it’s mostly sort of common sense. It looks like the skin is infected, or maybe long term having some skin discoloration.

Betsy Post 34:40
Thank you. And for our patients, we can start with Hope and then move to Michael. I want to know, based on what Dr. Ellis said about surgery, what your experience was with that, and what he said about the hospital stay, the scar, the surgery, the recovery, how does what he said compare with your experience?

Hope Brooks 35:03
For me, it’s pretty spot on. We were going to do my surgery robotically. My body didn’t cooperate, so he did this open incision after we were already in the operating room. I went into the regular room after recovery. A few hours after surgery, an hour or so, I was up walking almost immediately, and for myself the pain meds put me to sleep, so I asked them to turn that off. They had done epidural. We turned the epidural off. We started managing pain the first night withmedication, oral versus intravenously. Removed the epidural the next morning. After surgery, I spent that day in the hospital managing pain. For me, a muscle relaxer actually worked a little bit better than some of the narcotics. I’d never had abdominal surgery. Those of you who know me, I work out every single day. You know I’m picking up 100 plus pounds of kettlebells off the floor on a regular basis. So it was kind of a joke that my abdomen freaked out a little bit, so the Robaxin helped me, and then I went home the next day. So I was in the hospital two nights, and I went home the next day. It was uncomfortable, because it is a large metal object. I think the attachment to the abdominal wall was more uncomfortable than the incision itself. Just having it there. It has to settle in a little bit. Every week that went by, it got a little bit better. Probably after about the third week I was like, I can tolerate this. By two months, we got to know each other, and we became friends.

Michael Riehle 36:43
Yeah, for me, my surgery was robotic to have the the pump placed, but it was also done at the time of my colon resection. So my recovery process was a little different, obviously, than just the pump itself. I was in the hospital for maybe five days. I think, like you said, I do remember the pump study being the day following the implant being placed. So that was surprising to me, just because it was my first surgery ever in my life, and I’m like, “Oh, they already want to poke me with stuff”, but no, it was a pretty straightforward recovery. I just had some typical nausea and the normal pains that would come with with incisions, and then my bowels, waking back up from the colon resection, but I was back at work within five weeks, lightly going at it a little bit at a time, not jumping right into it, and as Hope said, within a couple of months. For me personally, I learned to live with it, and it almost just became part of me. I could hardly ever feel it was there unless I was squeezing into a tight place and I bumped it by accident, or the only time, oddly enough, I would ever really feel it would be if I was sitting on the ground and I would bend over at a weird angle to tie my shoe. That’s the only time I would ever actually feel it inside my body, which is weird to say, but yeah, it was pretty straightforward, and the recovery was pretty much what I would have expected.

Hope Brooks 38:12
I want to add on to that. My pump study was done the week after. So, it was a: Wednesday surgery; home on Friday; pump study on Tuesday. So I had to go back for that. But the tying of the shoes is accurate. I started working out four weeks after surgery, modified lighter weights and things, but tying my shoes still is the thing that gets me.

Michael Riehle 38:41
Yeah, it doesn’t hurt, but it’s just that one time where you actually can feel it just wedge a little bit in your body. Yeah.

Hope Brooks 38:47
And my pump was installed, stand alone. I had no other surgery with it.

Betsy Post 38:54
Thank you. And Megan’s here.

Megan Stevens 38:56
I am so sorry.

Betsy Post 38:57
Megan, that’s okay. We are very happy to have you here. I’ll get you in on this next round.

Megan Stevens 39:26
I absolutely apologize. Absolutely.

Betsy Post 39:27
That’s okay. So in the next round of questions, I’m going to tap you in. The next question, we have on initiating the HAI therapy. I know Dr. Turk, you actually talked about this a little bit, but how soon does HAI therapy start following the surgery?

Dr. Anita Turk 39:48
I think it depends on the surgery the patient has. In the patients where they’re just going in to get their pump placed, we’re not removing any segments of the liver to try to clear disease, you can often start at that first follow up visit in two weeks, as long as liver functions look okay. For patients who are planning to do pump after a complex liver resection, and we were worried about their remnant liver being high risk for still having cancer, sometimes it’d be challenging to start right away, and those folks usually need four, five weeks-ish to recover before we could start putting in floxuridine mainly because we just want those liver numbers to start coming back down, make sure those bile ducts are healed up, before we start administering the agent. The main concern that Dr. Ellis alluded to the risk with this therapy is called biliary sclerosis. So for those who may be less familiar, you have the liver itself and then there are tubes running through the liver that help form bile and excrete that into your stool. And that biliary tree is supplied by the hepatic artery so those cells are also getting exposed to this really strong chemotherapy agent. And whether it happens while you’re on the chemo, and it can even happen several months afterwards, those bile ducts can scar down from all the inflammation, and then the bile just doesn’t have anywhere to go. It’s almost like, when you see patients with end stage liver disease from hepatitis or something like that, they can develop a cirrhosis-like picture, where there’s a lot of scarring, the bilirubin goes up, and then options can, unfortunately, become very limited. So we’re very, very diligent about that to make sure we minimize that risk as much as possible. Going in with good liver numbers and your medical oncologist being familiar with how to dose this medication is very important. Again why I say go to a place that does this regularly. You don’t want to be going to a small volume center, not only from the expertise of the surgeon, but the expertise of the medical oncologist,

Megan Stevens 41:47
You’re muted Betsy.

Betsy Post 41:51
Sorry, I always mute so no one can hear my dog… So, with the systemic chemotherapy that’s generally done at the same time, we’d love to hear about the management of that, and then the treatment regimen during active HAI therapy. And one thing I want to tag into that, one question we see quite a bit is folks asking about side effects. So I’d love for you to talk about side effects, just as it relates to the HAI versus the systemic.

Dr. Anita Turk 42:23
Yeah. So again, whether that’s paired with systemic or not, would be a risk/benefit discussion with your medical oncologist. And the big picture in patients where I’m worried there’s cancer also outside the liver, but the liver’s problem number one in that moment we’ll often combine systemic chemotherapy with the pump. Chemotherapy to emphasize treatment to that liver, but also address other sites of disease. Commonly, what’s paired with the pump is irinotecan sometimes also 5-FU with the 48 hour pump. The reason we don’t like to do oxaliplatin, is because oxaliplatin also can hurt the tubes in the liver, all the bile ducts, so we want to avoid overlapping those as much as possible. Often when I pair it with the FOLFIRI chemotherapy, I do reduce the dose. There is a phase one study showing that that is safer for the bile ducts and liver function in general. So normally we dose that pump at full dose. If you pay attention to your dosage, I know many patients do that, it’s 2400. We’ll often bring that down closer to 1500 and irinotecan down closer to 100 where normal is 180 to try to mitigate those risks of liver toxicity. Now in the pump, in and of itself, side effects. It’s not often I get to tell my patients pretty much nothing, most of the toxicity, so to speak, in terms of acute side effects, is related to the pump itself. So, tying your shoe and feeling it. I had a patient whose grandson kicked him right in the pump and it flipped over. Mechanical issues can certainly happen, but from the Floxuridine itself, if that’s the only thing you’re getting, and I’m sure Michael and Hope can comment on this, it’s incredibly well tolerated. I’ve actually really never had a patient with symptoms acutely from that medication, outside of that biliary sclerosis issue.

Betsy Post 44:13
I’m going to switch to a patient question, and I’m going to put Megan on the spot here. What was your experience with getting your pump refilled?

Megan Stevens 44:30
You blanked out a little bit, but I understand that the question was, what’s my experience with getting my pump refilled.

Betsy Post 44:35
…Megan is a patient at Duke.

Megan Stevens 44:37
Yeah, I’m at Duke. When I was in active treatment, I would get my pump refilled at Duke. And it, oddly, doesn’t hurt for the needle to go into your belly. It’s awkward and you feel nervous. But then when it actually happens, it’s a bit of pressure, it’s a little pin prick. Like that. It doesn’t really hurt, and they would fill my pump up, and my oncologist was really conservative. I would get it refilled every six weeks, and I still am getting it refilled every six weeks. I’ve been off active treatment for three years now. I am a three year colon cancer survivor, and I attribute the HAI pump to my survival. At this point, I have a group called “Pentec” that comes to my house, and they do it on my couch. And so when I first started getting it refilled, I would go to Duke and I’d get my blood drawn on one level, I’d talk to my oncologist, or get scans on the next level, they would figure out what my liver levels were and decide what kind of infusion I needed, and then go to the next level and get it infused. And it was amazing, because it was all in one building. It was all on one day. And so I would go deal with my cancer in one day, deal with the side effects of the treatment after the fact, of course, but it wasn’t spread out. So I really liked that about Duke. And once I left active treatment and went on surveillance, we need to keep the pump – I call it changing my oil… We got to keep changing my oil, and I was going down to Duke every six weeks just to get my oil changed. And now they come to my house, and instead of getting lifted up on a table and having the whole room hush and the bright lights come on, they say, “All right, get on the table and grab a pillow”. And she’s very professional. She’s become a friend, and they do it in my house. That’s great.

Betsy Post 46:55
A question that someone had in the chat, Dr. Turk, I’m going to point this to you, because it goes with this. And that’s, how many days can patients extend beyond two weeks due to vacations or other obligations?

Dr. Anita Turk 47:07
That’s a great question. When I counsel a patient, before we get started, I really emphasize the importance of the every two weeks. I don’t like to deviate more than a couple of days from that. Again, running that risk of it running empty. So with these Intera pumps, I can’t program the rate. I’m calculating that rate when I empty it, so I see how much comes out. And I think, “Okay, how many days ago did I refill it?” And I do the math and see how fast it’s running. Knowing the approximate rate of a patient, assuming their body temperature has recently been stable, I can do the math and see how safe it is to extend it, depending on that patient’s pump, but it’s usually not more than a couple of days. Anytime I have a patient with a trip coming up and things like that, we try to adjust their pump fills to make sure, whenever they’re going out of town or they can’t come in, I know their pump is safe and that it’s going to be full with, whether it’s Heparin, glycerin, chemotherapy, wherever they’re at in their round of treatment,

Betsy Post 48:12
Great. And one other question before we move on to the next topic: Can a patient get the pump after having Y90?

Dr. Anita Turk 48:23
Great question. I get a little bit hesitant. It depends. I guess first, let me say it depends on the type of Y90 they had. There’s several different ways Y90 can be administered. It really depends on, were they going after the whole lobe? Were they going after assignment of the lobe? It really depends on what was going on: if they had gotten what we call a bilobar, or Y-mining, means they targeted both the lobes, and they got a pretty high dose where they have some liver issues chronically afterwards. That’s the patient I’m going to be nervous about, that their bile ducts aren’t going to be handling this. But patients who either had an IR doctor that was mindful of their doses, and the liver functions are doing okay? Or it was what we call segmental Y90. Where only a segment of the liver got it, not the whole liver, those patients would still be considered candidates. Ryan, anything to add there?

Dr. Ryan Ellis 49:13
Yeah, I would say people who have undergone Y90 more recently, as our technologies advance, -we’ve been a little bit more selective – are more likely to be candidates. I have certainly put pumps in patients who have had Y90 before. I will add one thing, which is the anatomic considerations can be complicated by Y90 in a small number of people, because of some of the arteries that I have to tie off and the way that I have to reconfigure the system if an artery that I absolutely need for the pump also was the main artery that the Y90 was delivered, that can rule it out, but it’s a case by case basis.

Betsy Post 49:55
Thank you. There are some questions in the live chat as well as some things that I had prepared to ask the patients. And I know I’m trying to look at the clock and make sure we stay on a good pace here, but this is about living with the pump, your daily life, your activities and your quality of life while living with a pump. And I think that this is really important. So I definitely want to talk about that. Also in the live Q and A, there are questions about what kind of physical activity can folks do with the pump? There’s a patient that says, “If I get this pump, I have a 13 month old baby… will I be able to lift my baby, put him on my hip, things like that?”. I would love to hear, I think we’ll start off with Michael just about physical activity, day to day life with the pump, and then move to Hope, if that’s okay with you?

Michael Riehle 50:45
Sure. Yeah, so, day to day life for the pump with me was after the that kind of learning period of a couple months, was pretty normal. I worked full time. I have a pretty physical job where I was climbing all over my trucks and getting into tight spaces and everything like that. My wife and I like to travel a lot, go hiking, go camping. We have some four wheelers. We like to go play in the woods and everything else. There really wasn’t… — I had to stay away from my hot tub, which we had unfortunately just gotten a month before my diagnosis. So that was kind of ironic. But other than staying away from the hot tub and stuff, really, nothing changed in my in my day to day life. You get used to where the pump is and certain things that you can or cannot do. Not that there wasn’t much that I couldn’t do with it, but you just would do it a little differently. If your body would want to move one way, you just have to remember where it was and how to react to it. So yeah, for me personally, it was almost like it wasn’t even there once you get used to it.

Betsy Post 51:56
Thank you. Hope?

Hope Brooks 52:00
I was actually afraid of that. That was the only hesitation I had when I was discussing the pump and getting it implanted. But come to find out, I was testing all the waters. I started out with, I don’t know, 10, 20, pounds of weight, and then worked my way back up. I went back to yoga. I don’t practice quiet, sit down yoga. I’m very active style yoga, and so I’ve been able to do everything I did before the pump. And again, just like Michael said, there’s a few postures or movements that you do have to adjust, just like the shoe – putting it on, you find a new way to do it if it works for you. Certain things don’t work. The twisting to the left doesn’t work as well. I can’t go as far. Certain things I would do on that side I just avoid if it bothers me, but I do everything that I did before. There’s not one thing I can think of other than a hot tub that I don’t do. I also practice hot yoga. So that was a difficult step. My surgeon and I discussed it at length, and I did a few tests on temperature, and I keep track of all of my usage of the pump in a spreadsheet like Dr. Turk was talking about, to figure out what my daily consumption was, and it was average, whether I was in the room once a week or if I was there six times a week. It didn’t change my core body temperature. Didn’t affect the pump and how it operated. So for me, I really was able to do everything. I go swimming in the summer. I’m a big water person. Nothing I can think of that I’m really missing other than a hot tub. I do take a bath, though. At first I was afraid I couldn’t take a bath, but I do take a bath.

Betsy Post 53:45
Megan, if you want to answer quickly as well. There’s also a question for Megan in the chat, so I’m going to tack it on here to this for you, and that’s that you had talked about, you’re just doing surveillance now. Are you just getting glycerin now?

Megan Stevens 53:59
I am just getting glycerin and it’s going well. I don’t know when we’re going to talk about taking the pump out. I’m hoping we’ll start talking about it. I’m actually, two and three quarter years, but I think I’m starting to get ready to have it out if I can. I mean, it’s a luxury to be able to be seeing the light at the end of the tunnel on this, but it’s also pretty awesome to know that that is possible, and that’s a thing that’s out there, that it’s real, and science gets better every day. I personally have been very weary about my movements with the pump. I have an 11 year old, and he was seven,- six and a half, seven, – when this all began, and I’ve just been really careful about it. I think it just depends on — everybody’s always on board saying they’ll do anything, and that’s great, and it’s wonderful. I think it’s a psychological thing for me. I’ve been very, very conservative with my exercise, which is showing because I’ve gained some weight, and I need to figure out how to get it back in line. But I’m alive. …That’s what I did.

Betsy Post 55:26
There are a couple questions in the chat that I think we should definitely answer. And this is something that comes up inCOLONTOWN as well. You’re talking about the biliary sclerosis, some of those chemo toxicity issues that can happen. So I’m going to weave a couple of questions here into one. This is something that comes up all the time, the discussion of the role of Ursodiol following HAI placement. And are there any others with Ursodiol? We’d love to hear your thoughts on that, but also any recommended standard of care medications that you can take while on pump chemo to help prevent with any of those liver toxicities. Or are these things that maybe you just get if the liver numbers rise? And then also, what liver function numbers do you specifically watch out for?

Dr. Anita Turk 56:20
Great question. So yes, the rates of biliary sclerosis are probably around 20% so it’s not an insignificant number. I’ve unfortunately lost one patient to that complication. So we are very, very vigilant about it. There is no data, unfortunately, about preventative measures. Of course we will use ursodiol if we are seeing signs of that problem, and really work closely with hepatology to help manage the health of your biliary tract. But right now, I don’t have great data to support any medication to help it be preventative. I will say the healthier you’re walking into it the better. And of course, it’s not just dealing with the cancer itself, but your general body. So hearing patients like Megan, Hope and Mike going into this, following up on their appointments, being really active, eating a balanced diet, things to minimize having a liver that’s already ill at baseline in the background, I think probably does help. Patients who have underlying cirrhosis walking into this, or with fatty liver disease, are more likely to have outcomes related directly to the chemotherapy than those who don’t have those baseline problems. So I think general health is probably the best thing in our pocket going into something like this. Again, I cannot emphasize enough the importance of physical activity to help with all of that, and I apologize, what was the other question? Think it was not just the ursodiol, but if there are any other medications that you recommend or could take. But then also the other part was, at what point do those numbers become concerning, and is it a specific number you’re looking for, like the alkaline phosphatase? Right, yes. So the most important number–we look at all the liver numbers but the most important ones are the alkaline phosphatase, the bilirubin, we do also look at AST and ALT. I’m sure many people on this meeting today are familiar with looking at those numbers while they’re on chemotherapy, but they don’t have to be in the red to be a problem. So I have patients where I start this medication, and their alkaline phosphatase is in the 90’s, but they jump to the 120’s that’s still normal at our lab at IU. But that’s just the fact that it went up is a problem. So we take any rises very seriously. So the other medications that we use, in addition to ursodiol, would be for very severe cases, but where the patient’s doing fine, their liver numbers are still technically okay but have gone up from baseline, is adding steroid to those heparin days to help bring those numbers down and dose reducing that chemotherapy once those liver numbers have improved to make sure we don’t cause repeat injury. So again, I’ve said this again. I’m going to say it again. It is very important you’re going to a center that is familiar with how to dose floxuridine and manage these toxicities, because they can be very serious.

Betsy Post 59:22
This is for the patients: I would love to know what you would like to tell other patients that are considering the HAI pump, and then, along with what you’d tell them to consider, what might you want to tell them to ask their oncologist? Anyone want to go first? Hope maybe?

Hope Brooks 59:48
Oh, just one second, let me think. I guess my question would be, “Why am I a candidate for the HAI, if it is an opportunity for me?”, becausefrom what I understood when I met with Dr. Chung, because I had a good response to the FOLFIRINOX, it was assumed that I would likely have a very good response to the FUDR. So that’s a question for me is, how does that work? Had I known more than I know – the list of questions on the patient questionnaire that’s been recently published. Those are questions that a lot of them came from me, that I asked. Those are things I wish I had known outside of the single question. There’s several of them that I wish I had asked ahead of time, but I learned later. So hopefully that’s a guide to somebody.

Betsy Post 1:00:38
Great. Megan, anything you think patients should know?

Megan Stevens 1:00:55
It’s hard. So I had gone through several doctors before I made my way to Duke, and I’m driving three hours to get there every time, three hours back. And it was worthwhile, because I trusted them, and as soon as I knew I was in hands that I fully trusted, I just let go of all need to control, and I put my faith in them and let it be. But I think I would want to know if this was closing down any other opportunities for treatment. With the advancements of technology and medicine as it is, you want to always keep as many options open, and if something closes down options, to me, that’s a red flag, because the more options you have, the longer you will be able to fight this, and the closer you’ll get to having a solution and a resolution to it. So I guess that would be my question: “Does getting the HAI pump close down any options for me moving forward?” Because you’re always playing the long game, there’s not a short answer, there’s not a fast answer. You are in this for the long game, and you’ve got to have as many options as you can to get to the end. That’s what I would think.

Betsy Post 1:02:31
Thank you. Michael, anything to add?

Michael Riehle 1:02:34
I guess my biggest advice would be kind of similar to what Dr. Turk said about making sure you go to a reputable place for something like HAI therapy, instead of just going to maybe just your local center that they started picking them up last year or the year before, and they don’t have as much experience in it. Because the potential of risk is so high, you really want to have someone that knows what they’re doing and has the utmost experience with it. So if it’s something where you have to travel, try to find a way to make that work, to get to the best place, to give you the best care, as difficult as it may be. I mean, a lot of us are here because we got ourselves to these places to get these things done, through these top places. So that will be my biggest advice.

Betsy Post 1:03:25
Thank you. And it’s 8:04, so I’m going to wrap up a tiny bit, but there is a question in here I definitely think we should answer, and that’s if you have a recurrence with the pump. Can you still have resection or ablation, or is it more favorable to treat with chemo only? So I think that’s an important question for us to answer. Maybe Dr. Ellis, you could take that one.

Dr. Ryan Ellis 1:03:55
Sure. I apologize, my internet has been on the fritz, so if I fade away, that’s the issue. So yes, it is. It’s totally appropriate to have additional procedures on the liver after the hepatic artery pump has been placed. If I remember his story correctly, sounds like Michael actually started with a pump alone. There are multiple pathways, wherein when I see someone who we’re considering, Dr. Turk talked in general about the indications being unresectable disease, adjuvant disease, and in all cases, there’s chances that even after you’ve had all of your disease cleared either before or after the pump is placed initially, the disease can come back, and we do routinely do additional local therapies. Y90 is more or less off the table once a pump is in but the resections and ablations can absolutely happen if you have a local recurrence in the liver after the pump is placed.

Betsy Post 1:05:09
So I just want to leave it to the patients to wrap up. Is there anything Hope, Michael, Megan, that we haven’t talked about tonight, anything you think is important that you’d like to say to any of the patients that are watching tonight or in the future, but it’s okay if you don’t either. That’s okay. I don’t want to put you on the spot too much, but parting words from from our patients that have done this therapy and have had different types of results. You’re all from different centers and and your stories are all a little different.

Hope Brooks 1:05:47
I would like to say, because I’m not on active pump treatment right now. -We’re dealing with a few questionable lung mets, but otherwise, I’m clear of disease at this moment. I’ve two times used my pump for a recurrence, and it worked wonderfully. So I look at it like you have to know that you’re going to get married to this pump for three to five years and be ready for that long haul and be able to ask the questions. And there’s a lot of tools out there that weren’t even out there a year and a half ago or in December of ’22 when I got my pump. So ask for those materials. Ask to be educated on the pump. If you have hesitations, ask to speak with a patient. There’s a lot of oncologists and surgeons that will have patients of theirs that you can speak to, that might be local to you, or somebody in the groups in COLONTOWN that can help you as well. So one, don’t be afraid to ask the question. Two, don’t be afraid to travel and try to utilize the tools that are out there to see if this is the right fit for you. It changed my life. I don’t think I’d be here without it, I’m 99% sure of that.

Megan Stevens 1:06:51
Yeah, I think there’s one thing I’ve worked with, – I’ve been friends with, been close to other cancer patients, and a lot of times they were nervous that they would hurt the feelings of their doctor if they got a second opinion. They didn’t want to offend anybody by getting a second opinion. Doctors are not going to be offended by you getting a second opinion. You are in your absolute right to get as many opinions as you want from doctors all over the globe. And doctors are good people. They want to save your life. They want to give you an opinion. And you shouldn’t fear reaching out to other people.

Michael Riehle 1:07:45
I’ll echo what Megan hope said, just don’t be afraid to reach out to anyone, whether it’s another patient or other doctors, because they’re your lifelines. So don’t be afraid to reach out.

Betsy Post 1:07:59
Thank you, Dr. Turk, Dr. Ellis, thank you so much for being here on the panel this evening. I know I’ve learned some things too. And thank you so much to our patients. Hope, Michael, Megan, we really appreciate your time. And thanks to everyone that attended live and of course, all of those that will be watching the recording. And I just wanted to leave the final word to Dr. Turk, Dr. Ellis. Is there anything that you’d like to add, anything that we didn’t cover tonight that you think is important?

Dr. Anita Turk 1:08:32
No, I can’t think of anything. I think we’ve covered at least the basics of pump therapy. Again, a lot of it’s a case by case situation. And just get that second opinion. I promise you your oncologist is not going to be offended. We all just want to help.

Dr. Ryan Ellis 1:08:48
Likewise, great discussion. I thank the panelists for their time.

Betsy Post 1:08:55
Thank you all so much. Have a great evening. Thank you.
