On the inaugural episode of ASCO Education: By the Book, Dr. Nathan Pennell and Dr. Don Dizon share reflections on the evolution of the ASCO Educational Book, its global reach, and the role of its new companion podcast to further shine a spotlight on the issues shaping the future of modern oncology. TRANSCRIPT Dr. Nathan Pennell: Hello, I'm Dr. Nate Pennell, welcoming you to the first episode of our new podcast, ASCO Education: By the Book. The podcast will feature engaging discussions between editors and authors from the ASCO Educational Book. Each month, you'll hear nuanced views on key topics in oncology featured in Education Sessions at ASCO meetings, as well as some deep dives on the advances shaping modern oncology. Although I am honored to serve as the editor-in-chief (EIC) of the ASCO Educational Book, in my day job, I am the co-director of the Cleveland Clinic Lung Cancer Program and vice chair for clinical research for the Taussig Cancer Center here in Cleveland. I'm delighted to kick off our new podcast with a discussion featuring the Ed Book's previous editor-in-chief. Dr. Don Dizon is a professor of medicine and surgery at Brown University and works as a medical oncologist specializing in breast and pelvic malignancies at Lifespan Cancer Institute in Rhode Island. Dr. Dizon also serves as the vice chair for membership and accrual at the SWOG Cancer Research Network. Don, it's great to have you here for our first episode of ASCO Education: By the Book. Dr. Don Dizon: Really nice to be here and to see you again, my friend. Dr. Nathan Pennell: This was the first thing I thought of when we were kicking off a podcast that I thought we would set the stage for our hopefully many, many listeners to learn a little bit about what the Ed Book used to be like, how it has evolved over the last 14 years or so since we both started here and where it's going. You started as editor-in-chief in 2012, is that right? Dr. Don Dizon: Oh, boy. I believe that is correct, yes. I did two 5-year stints as EIC of the Educational Book, so that sounds about right. Although you're aging me very clearly on this podcast. Dr. Nathan Pennell: I had to go back in my emails to see if I could figure out when we started on this because we've been working on it for some time. Start out a little bit by telling me what do you remember about the Ed Book from back in the day when you were applying to be editor-in-chief and thinking about the Ed Book. What was it like at that time? Dr. Don Dizon: You know, it's so interesting to think about it.  Ten years ago, we were both in a very different place in our careers, and I remember when the Ed Book position came up, I had been writing a column for ASCO. I had done some editorial activities with other journals for sure, but what always struck me was it was very unclear how one was chosen to be a part of the education program at ASCO. And then it was very unclear how those faculty were then selected to write a paper for the Educational Book. And it was back in the day when the Educational Book was completely printed. So, there was this book that was cherished among American fellows in oncology. And it was one that, when I was newly attending, and certainly two or three years before the editor's position came up, it was one that I referenced all the time. So, it was a known commodity for many of us. And there was a certain sense of selectivity about who was invited to write in it. And it wasn't terribly transparent either. So, when the opportunity to apply for editor-in-chief of the Educational Book came up, I had already been doing so much work for ASCO. I had been on the planning committees and served in many roles across the organization, and editing was something I found I enjoyed in other work. So, I decided to put my name in the ring with the intention of sort of bringing the book forward, getting it indexed, for example, so that there was this credit that was more than just societal credit at ASCO. This ended up being something that was referenced and acknowledged as an important paper through PubMed indexing. And then also to provide it as a space where we could be more transparent about who was being invited and broadening the tent as to who could participate as an author in the Ed Book. Dr. Nathan Pennell: It's going to be surprising to many of our younger listeners to learn that the Educational Book used to be just this giant, almost like a brick. I mean, it was this huge tome of articles from the Education Sessions that you got when you got your meeting abstracts book at the annual meeting. And you can always see people on the plane on the way out of Chicago with their giant books. Dr. Don Dizon: Yes. Dr. Nathan Pennell: That added lots of additional weight to the plane, I'm sure, on the way out. Dr. Don Dizon: And it was not uncommon for us to be sitting at an airport, and people would be reading those books with highlighters. Dr. Nathan Pennell: I fondly remember being a fellow and coming up and the Ed Book was always really important to me, so I was excited. We'll also let the listeners in on that. I also applied to be the original editor-in-chief of the Ed Book back in 2012, although I was very junior and did not have any real editorial experience. I think I may have been section editor for The Oncologist at that point. And I had spoken to Dr. Ramaswamy Govindan at WashU who had been the previous editor-in-chief about applying and he was like, “Oh yeah. You should absolutely try that out.” And then when Dr. Dizon was chosen, I was like, “Oh, well. I guess I didn't get it.” And then out of the blue I got a call asking me to join as the associate editor, which I was really always very thankful for that opportunity. Dr. Don Dizon: Well, it was a highly fruitful collaboration, I think, between you and I when we first started. I do remember taking on the reins and sort of saying, “You know, this is our vision of what we want to do.” But then just working with the authors, which we did, about how to construct their papers and what we were looking for, all of that is something I look back really fondly on. Dr. Nathan Pennell: I think it was interesting too because neither one of us had really a lot of transparency into how things worked when we started. We kind of made it up a little bit as we went along. We wanted to get all of the faculty, or at least as many of them as possible contributing to these. And we would go to the ASCO Education Committee meeting and kind of talk about the Ed Book, and we were thinking about, you know, how could we get people to submit. So, at the time it wasn't PubMed indexed. Most people, I think, submitted individual manuscripts just from their talk, which could be anywhere from full length review articles to very brief manuscripts. Dr. Don Dizon: Sometimes it was their slides with like a couple of comments on it. Dr. Nathan Pennell: And some of them were almost like a summary of the talk. Yeah, exactly. And so sort of making that a little more uniform. There was originally an honorarium attached, which went away, but I think PubMed indexing was probably the biggest incentive for people to join. I remember that was one of the first things you really wanted to get. Dr. Don Dizon Yeah. And, you know, it was fortuitous. I'd like to take all the credit for it, but ASCO was very forward thinking with Dr. Ramaswamy and the conversations about going to PubMed with this had preceded my coming in. We knew what we needed to do to get this acknowledged, which was really strengthening the peer review so that these papers could meet the bar to get on PubMed. But you know, within the first, what, two or three years, Nate, of us doing this, we were able to get this accepted. And now it is. If you look at what PubMed did for us, it not only increased the potential of who was going to access it, but for, I think the oncology community, it allowed people access to papers by key opinion leaders that was not blocked by a paywall. And I thought that was just super important at the time. Social media was something, but it wasn't what it is now. But anybody could access these manuscripts and it's still the case today. Dr. Nathan Pennell: I think it's hard to overstate how important that was. People don't realize this, but the Ed Book is really widely accessed, especially outside the US as well. And a lot of people who can't attend the meeting to get the print, well, the once print, book could actually get access to essentially the education session from the annual meeting without having to fly all the way to the US to attend. Now, you know, we have much better virtual meeting offerings now and whatnot. But at the time it was pretty revolutionary to be able to do that. Dr. Don Dizon: Yeah, and you know, it's so interesting when I think back to, you know, this sort of evolution to a fully online publication of the Ed Book. It was really some requests from international participants of the annual meeting who really wanted to continue to see this in print. At that time, it was important to recognize that access to information was not uniform across the world. And people really wanted that print edition, maybe not for themselves, but so that access in more rural areas or where access in the broadband networks were not established that they still could access the book. I think things have changed now. We were able, I think, in your tenure, to see it fully go online. But even I just remember that being a concern as we went forward. Dr. Nathan Pennell: Yeah, we continued with the print book that was available if people asked for it, but apparently few enough people asked for it that it moved fully online. One of the major advantages of being fully online now is of course, it does allow us to publish kind of in real time as the manuscripts come out in the months leading up to the meeting, which has been, I think, a huge boon because it can build momentum for the Education Sessions coming in. People, you know, really look forward to it. Dr. Don Dizon: Yeah, that was actually a concern, you know, when we were phasing out Ed Book and going to this continuous publication model where authors actually had the ability to sort of revise their manuscript and that would be automatically uploaded. You had a static manuscript that was fully printed, and it was no longer an accurate one. And we did have the ability to fix it. And it just goes to show exactly what you're saying. This idea that these are living papers was really an important thing that ASCO embraced quite early, I think. Dr. Nathan Pennell: And with the onset of PubMed indexing, the participation from faculty skyrocketed and almost within a couple of years was up to the vast majority of sessions and faculty participating. Now I think people really understand that this is part of the whole process. But at the time I remember writing out on my slides in all caps, “THIS IS AN EXPECTATION.” And that's about the best word I could give because I asked if we could make people do it, and they were like, no, you can't make people do it. Dr. Don Dizon: So right.  Actually, I don't think people are aware of the work on the back end every year when I was on as EIC, Nate and myself, and then subsequently Dr. Hope Rugo would have these informational sessions with the education faculty and we would tout the Ed Book, tout the expectation, tout it was PubMed indexed and tout multidisciplinary participation. So, we were not seeing four manuscripts reflecting one session. You know, this encouragement to really embrace multidisciplinary care was something that very early on we introduced and really encouraged people not to submit perspective manuscripts, but to really get them in and then harmonize the paper so that it felt like it was, you know, one voice. Dr. Nathan Pennell: I consider that after PubMed indexing, the next major change to the Ed Book, that really made it a better product and that was moving from, you know, just these short individual single author manuscripts to single session combined manuscript that had multiple perspectives and topics, really much more comprehensive review articles. And I don't even remember what the impetus was for that, but it was really a success. Dr. Don Dizon: Yeah, I mean, I think in the beginning it was more of a challenge, I think, because people were really not given guidance on what these papers were supposed to look like. So, we were seeing individual manuscripts come forward. Looking back, it really foreshadowed the importance of multidisciplinary management. But at the time, it was really more about ensuring that people were leaving the session with a singular message of what to do when you're in clinic again. And the goal was to have the manuscripts reflect that sort of consensus view of a topic that was coming in. There were certain things that people still argued would not fit in a multidisciplinary manuscript. You know, if you have someone who's writing and whose entire talk was on the pathology of thyroid cancer. Another topic was on survivorship after thyroid cancer. It was hard to sort of get those two to interact and cover what was being covered. So, we were still getting that. But you're right, at the end of my tenure and into yours, there were far fewer of those individual manuscripts. Dr. Nathan Pennell: And I think it's even made it easier to write because now, you know, you just have to write a section of a manuscript and not put together an entire review. So, it has helped with getting people on board. Dr. Don Dizon: Well, the other thing I thought was really interesting about the process is when you're invited to do an Education Session at ASCO, you're either invited as a faculty speaker or as the chair of the session. And the responsibility of the chair is to ensure that it flows well and that the talks are succinct based on what the agenda or the objectives were as defined by the education committee for that specific group. But that was it. So really being named “Chair” was sort of an honor, an honorific. It really didn't come with responsibility. So, we use the Ed Book as a way to say, “As chair of the session, it is your responsibility to ensure A, a manuscript comes to me, but B, that the content of that paper harmonizes and is accurate.” And it was very rare, but Nate, I think we got dragged into a couple of times where the accuracy of the manuscript was really called into question by the chair. And those were always very, very tricky discussions because everyone that gets invited to ASCO is a recognized leader in their field. Some of us, especially, I would probably say, dating back 10 years from today, the data behind Standards of Care were not necessarily evidence-based. So, there were a lot of opinion-based therapies. You know, maybe not so much in the medical side, but certainly some of it. But when you went to, you know, surgical treatments and maybe even radiotherapy treatments, it was really based on, “My experience at my center is this and this is why I do what I do.” But those kinds of things ended up being some of the more challenging things to handle as an editor. Dr. Nathan Pennell: And those are the– I'll use “fun” in a broad sense. You know, every once in a while, you get an article where it really does take a lot of hands-on work from the editor to work with the author to try to revise it and make it a suitable academic manuscript. But you know what? I can't think, at least in recent years, of any manuscripts that we turned down. They just sometimes needed a little TLC. Dr. Don Dizon: Yeah. And I think the other important thing it reminds me of is how great it was that I wasn't doing this by myself. Because it was so great to be able to reach out to you and say, “Can you give me your take on this paper?” Or, “Can you help me just join a conference call with the authors to make sure that we're on the same page?” And then on the rare example where we were going to reject a paper, it was really important that we, as the editorial team, and I include our ASCO shepherder, through the whole process. We had to all agree that this was not salvageable. Fortunately, it happened very rarely. But I've got to say, not doing this job alone was one of the more important facets of being the EIC of ASCO's Educational Book. Dr. Nathan Pennell: Well, it's nice to hear you say that. I definitely felt that this was a partnership, you know, it was a labor of love. So, I want to go to what I consider sort of the third major pillar of the changes to the Ed Book during your tenure, and that was the introduction of a whole new kind of manuscript. So up to, I don't know, maybe seven or eight years ago, all the articles were authored just by people who were presenting at the Annual Meeting. And then you had an idea to introduce invited manuscripts. So take me through that. Dr. Don Dizon: Yeah, well, you know, again, it went to this sort of, what can people who are being asked to sort of lead ASCO for that year, what can they demonstrate as sort of a more tangible contribution to the Society and to oncology in general? And I think that was the impetus to use the Ed Book for everyone who was in a leadership position to make their mark. That said, I was here, and I was either president of the society or I was Education Program Chair or Scientific Program Chair, and they got to select an article type that was not being covered in the annual meeting and suggest the authors and work with those authors to construct a manuscript. Never did any one of those folks suggest themselves, which I thought was fascinating. They didn't say, “I want to be the one to write this piece,” because this was never meant to be a presidential speech or a commemorative speech or opportunity for them as leaders. But we wanted to ensure that whatever passion they had within oncology was represented in the book. And again, it was this sort of sense of, I want everyone to look at the Ed Book and see themselves in it and see what they contributed. And that was really important for those who were really shepherding each Annual Meeting each year for ASCO that they had the opportunity to do that. And I was really pleased that leadership really took to that idea and were very excited about bringing ideas and also author groups into the Educational Book who would not have had the opportunity otherwise. I thought that was just really nice. It was about inclusiveness and just making sure that people had the opportunity to say, “If you want to participate, we want you to participate.” Dr. Nathan Pennell: Yeah, I agree. I think the ASCO leadership jumped on this and continues to still really appreciate the opportunity to be able to kind of invite someone on a topic that's meaningful to them. I think we've tried to work in things that incorporate the presidential theme each year in our invited manuscript, so it really allows them to put kind of a stamp on the flavor of each edition. And the numbers reflect that these tend to be among our more highly read articles as well. Dr. Don Dizon: You know, looking back on what we did together, that was something I'm really, really quite proud of, that we were able to sort of help the Educational Book evolve that way. Dr. Nathan Pennell: I agree. You brought up briefly a few minutes ago about social media and its role over time. I think when we started in 2012, I had just joined Twitter now X in 2011, and I think we were both sort of early adopters in the social media. Do you feel like social media has had a role in the growth of the Ed Book or is this something that you think we can develop further? Dr. Don Dizon: When we were doing Ed Book together, professional social media was actually a quite identified space. You know, we were all on the same platform. We analyzed what the outcomes were on that platform and our communities gathered on that platform. So, it was a really good place to highlight what we were publishing, especially as we went to continuous publishing.  I don't remember if it was you or me, but we even started asking our authors for a tweet and those tweets needed work. It was you. It was you or I would actually lay in these tweets to say, “Yeah, we need to just, you know, work on this.” But I think it's harder today. There's no one preferred platform. Alternate platforms are still evolving. So, I think there are opportunities there. The question is: Is that opportunity meaningful enough for the Ed Book to demonstrate its return on an investment, for example? What I always thought about social media, and it's still true today, is that it will get eyes on whatever you're looking at far beyond who you intended to see it. So, you know, your tweets regarding a phase 3 clinical trial in lung cancer, which were so informative, were reaching me, who was not a lung oncologist who doesn't even see lung cancer and getting me more interested in finding that article and more and more pointing to the Educational Book content that speaks to that piece, you know. And I think coupling an impression of the data, associating that with something that is freely accessed is, I think, a golden opportunity not only for our colleagues, but also for anyone who's interested in a topic. Whether you are diagnosed with that cancer or you are taking care of someone with that cancer, or you heard about that cancer, there are people who would like to see information that is relevant and embedded and delivered by people who know what they're talking about. And I think our voices on social media are important because of it. And I think that's where the contribution is. So, if we had to see what the metric was for any social media efforts, it has to be more of the click rates, not just by ASCO members, but the click rates across societies and across countries. Dr. Nathan Pennell: Yeah, social media is, I mean, obviously evolving quite a bit in the last couple of years. But I do know that in terms the alt metrics for the track access through social media and online, the ones that are shared online by the authors, by the Ed Book team, do seem to get more attention. I think a lot of people don't like to just sit with a print journal anymore or an email table of contents for specific journals. People find these articles that are meaningful to them through their network and oftentimes that is online on social media. Dr. Don Dizon: Yes, 100%. And you know what I think we should encourage people to do is look at the source. And if the Ed Book becomes a source of information, I think that will be a plus to the conversations in our world. We're still dealing with a place where, depending on who sponsored the trial, whether it was an industry-sponsored trial, whether it was NCI sponsored or sponsored by the National Institutes of Health, for example, access to the primary data sets may or may not be available across the world, but the Ed Book is. And if the Ed Book can summarize that data and use terms and words that are accessible no matter what your grade level of education is. If we can explain the graphs and the figures in a way that people can actually easily more understand it. If there's a way that we structure our conversations in the Ed Book so that the plethora of inclusion/exclusion criteria are summarized and simplified, then I think we can achieve a place where good information becomes more accessible, and we can point to a summary of the source data in places where the source is not available. Dr. Nathan Pennell: One of the other things that I continue to be surprised at how popular these podcasts are. And that gives you an opportunity pretty much the opposite. Instead of sort of a nugget that directs you to the source material, you've got a more in-depth discussion of the manuscript. And so, I'm delighted that we have our own podcast. For many years, the Ed Book would sort of do a sort of a “Weird Al takeover” of the ASCO Daily News Podcast for a couple of episodes around the Annual Meeting, and I think those were always really popular enough that we were able to argue that we deserved our own podcast. And I'm really looking forward to having these in-depth discussions with authors. Dr. Don Dizon: It's an amazing evolution of where the Ed Book has gone, right? We took it from print only, societally only, to something that is now accessed worldwide via PubMed. We took it from book to fully online print. And now I think making the content live is a natural next step. So, I applaud you for doing the podcast and giving people an opportunity actually to discuss what their article discusses. And if there's a controversial point, giving them the freedom and the opportunity to sort of give more nuanced views on what may not be something that there's 100% consensus over. Dr. Nathan Pennell: Yes. Well, I hope other people enjoy these as well. Just want to highlight a few of the things that have happened just in the couple years since you stepped down as editor-in-chief. One of them, and I don't know if you noticed, but last year we started adding manuscripts from the ASCO thematic meetings, so ASCO GI and ASCO GU, something we had certainly talked about in the past, but had lacked bandwidth to really do. And they seem to be pretty widely accessed. Dr. Don Dizon: That's fantastic. Yes, I do remember talking about the coverage of the thematic meetings and you're right, this takes a long time to sort of concentrate on the Annual Meeting. It may seem like everything happens in the span of like eight weeks. Dr. Nathan Pennell: It does feel like that sometimes. Dr. Don Dizon: Right? But this is actually something that starts a year before, once the education program is set. We're in the room when they set it. But then it's really chasing down manuscripts and then making sure that they're peer reviewed because the peer review is still really important, and then making sure that any revisions are made before it's finalized and goes to press. That is a many months process. So, when we're trying to introduce, “Oh, we should also do ASCO GU or-,” the question was, how do you want to do that given this very, very involved process going forward? So, I'm glad you were able to figure it out. Dr. Nathan Pennell: Well, it's challenging. I don't think people realize quite the compressed timeline for these. You know, the Education Session and authors and invited faculty are picked in the fall, and then basically you have to start turning in your manuscripts in February, March of the following year. And so, it's a really tight turnaround for this. When we talk about the ASCO thematic meetings, it's an even tighter window. Dr. Don Dizon: Right, exactly. Dr. Nathan Pennell: And so, it's challenging to get that moving, but I was really, really proud that we were able to pull that off. Dr. Don Dizon: Well, congratulations again. And I think that is a necessary step, because so much of what's going on in the various disease management sites is only covered cursorily through the Annual Meeting itself. I mean, there's just so much science breaking at any one time that I think if we want to comprehensively catalog the Year in Review in oncology, it kind of behooves us to do that. Dr. Nathan Pennell: Some other things that are coming up because we now have manuscripts that are going to be coming in year-round, and just to kind of make it easier on the editorial staff, we're going to be forming an editorial board. And in addition to our pool of reviewers who get ASCO points, please feel free to go online to the ASCO volunteer portal and sign up if you are interested in participating. So, moving forward, I'm really excited to see where things are going to go. Dr. Don Dizon: Well, that's great. That's great. And I do remember talking about whether or not we needed to have an editorial board. At least when I was there, having this carried by three people was always better than having it carried by one person. And I think as you expand the potential for submissions, it will be very helpful to have that input for sure. And then it gives another opportunity for more members to get involved in ASCO as well. Dr. Nathan Pennell: Absolutely. People want involvement, and so happy to provide that. Dr. Don Dizon: Yes. Dr. Nathan Pennell: Is there anything we didn't cover that you would like to mention before we wrap up? Dr. Don Dizon: Well, I will say this, that ASCO and through its publications not only has had this real emphasis on multidisciplinary management of cancers, especially where it was relevant, but it also always had a stand to ensure representation was front and center and who wrote for us. And I think every president, every chair that I've worked with naturally embraced that idea of representation. And I think it has been a distinct honor to say that during my tenure as EIC, we have always had a plethora of voices, of authors from different countries, of genders, that have participated in the construction of those books. And it stands as a testament that we are a global community and we will always be one. Dr. Nathan Pennell: Well, thank you for that. And I'm happy to continue that as we move forward. Well, Don, thank you. It's been great speaking with you. You played such a pivotal role in the Ed Book's evolution and I'm so glad you were able to join me for our inaugural episode. Dr. Don Dizon: Well, I'm just tickled that you asked me to be your first guest. Thank you so much, Nate. Dr. Nathan Pennell: And I also want to thank our listeners for joining us today. We hope you'll join us again for more insightful views on topics you'll be hearing at the Education Sessions from ASCO meetings throughout the year, as well as our periodic deep dives on advances that are shaping modern oncology.

Send us a textWelcome to The Oncology Journal Club Podcast Series 3! Proudly produced by The Oncology NetworkThree respected oncologists dive deep into the most significant research presented at ASCO GI 2025, bringing you practice-changing insights amidst a backdrop of political uncertainty affecting medical research.Professor Chris Karapetis joins hosts Professor Craig Underhill and Professor Christopher Jackson to unpack ground-breaking colorectal cancer studies that are reshaping treatment paradigms. The conversation explores how targeted therapies are dramatically improving survival rates, with the DEEPER study demonstrating cetuximab's superiority over bevacizumab for left-sided RAS wild-type disease, achieving an impressive 50-month median survival when combined with chemotherapy.The experts dissect the BREAKWATER trial, which shows promising benefits of combining encorafenib and cetuximab with chemotherapy for notoriously aggressive BRAF-mutant colorectal cancer. This combination achieved a 61% response rate versus 40% with standard care, with responses lasting significantly longer – representing a potential new standard of care for this difficult-to-treat subgroup.Perhaps most surprisingly, our panel discusses how an inexpensive, familiar medication – aspirin – could reduce colorectal cancer recurrence by 40% in patients with PIK3CA mutations according to the ALASCCA study. This finding highlights how molecular profiling is becoming essential across treatment stages, not just for expensive targeted therapies but also for optimising use of accessible interventions.The discussion extends to exciting developments in pancreatic cancer with a novel pan-RAS inhibitor showing meaningful activity, and advancements in immunotherapy for MSI-high colorectal cancer, confirming combination therapy's superiority. For gastrointestinal oncologists navigating an increasingly complex treatment landscape, this episode offers crucial insights to optimise patient outcomes through precise, personalised approaches.Subscribe to The Oncology Newsletter for regular updates on the latest cancer research and join our community at oncologynetwork.com.au.The Oncology Podcast - An Australian Oncology Perspective

After the 2024 Gastrointestinal Cancers Symposium, Jun Gong, MD, and Daneng Li, MD, sat down to discuss the most relevant trial data to have come from the conference. They convened for a live X Space hosted by CancerNetwork®. During the discussion, they covered different trials across the gastrointestinal space, which included those evaluating different disease states from hepatocellular carcinoma (HCC) to colorectal cancer (CRC), and those assessing circulating tumor DNA (ctDNA) dynamics. Gong, a hematologic oncologist focusing on gastrointestinal and genitourinary cancers at Cedars-Sinai Medical Center, and Li, an associate professor in the Department of Medical Oncology and Therapeutics Research at City of Hope, each gave their perspective on the clinical trial data and discussed if they had implemented any of these study treatments into clinical practice.  The studies they covered included:  1.        Phase 3 NETTER-2 Trial (NCT03972488)1: - Investigated lutetium Lu 177 dotatate (Lutathera) plus octreotide vs octreotide alone for advanced gastroenteropancreatic neuroendocrine tumors (GEP-NETs). - Lutetium Lu 177 significantly improved progression-free survival (PFS) and overall response rate (ORR) compared with octreotide alone. - The agent may be considered for patients with high-grade GEP-NETs who desire significant tumor shrinkage. 2.        Phase 3 EMERALD-1 Trial (NCT03778957)2: - Studied transarterial chemoembolization (TACE) plus durvalumab (Imfinzi) with or without bevacizumab (Avastin) for unresectable HCC. - Durvalumab/bevacizumab plus TACE improved PFS compared with placebo plus TACE. - TACE may be preferred over transarterial radioembolization (TARE) due to faster patient recovery. 3.        Phase 3 CheckMate-8HW Trial3: - Evaluated nivolumab (Opdivo) plus ipilimumab (Yervoy) vs chemotherapy for first-line treatment of microsatellite instability-high/mismatch repair deficient metastatic CRC. - Nivolumab/ipilimumab demonstrated superior PFS compared with chemotherapy. - Chemotherapy may no longer be the standard first-line treatment for this patient population. 4.        BESPOKE Study (NCT04264702)4: - Assessed the impact of minimal residual disease (MRD) detected by ctDNA on disease recurrence in patients with stage II and III CRC receiving adjuvant chemotherapy. - MRD positivity was associated with worse disease-free survival (DFS). - ctDNA clearance at 12 weeks indicated improved DFS.  5.        GALAXY Trial5: - ctDNA is a promising biomarker that can be used to predict recurrence in patients with CRC. - Patients with ctDNA-positive disease had a worse DFS than patients with ctDNA-negative disease. - This suggests that ctDNA may be useful for making treatment decisions, but more research is needed before it can be used in clinical practice. 6.        Phase 3 FRESCO-2 Trial (NCT04322539)6: - Fruquintinib (Fruzaqla) improved the quality of life in patients with metastatic CRC when combined with best supportive care and significantly improved quality-adjusted time without symptoms of disease or toxicity compared with placebo and best supportive care. - The study showed positive effects on PFS, response rate, disease control, and duration of response with the fruquintinib combination. - The findings from this trial supported the FDA approval of fruquintinib for metastatic CRC in November 2023.7 References 1.        Singh S, Halperin D, Myrehaug S, et al.

In this podcast, we will discuss key insights from the 2024 ASCO Gastrointestinal (GI) Cancers Symposium held in San Francisco,... The post Esophageal and gastric cancer highlights from ASCO GI 2024 appeared first on VJOncology.

Drs. Shaalan Beg and Rachna Shroff discuss key abstracts on GI cancers that were featured at the 2024 ASCO Gastrointestinal Cancers Symposium, including SKYSCRAPER-08, EMERALD-1, and NEST-1 in esophageal squamous cell carcinoma, hepatocellular carcinoma, and colorectal cancer, respectively. TRANSCRIPT Dr. Shaalan Beg: Hello, and welcome to the ASCO Daily News Podcast. I'm Dr. Shaalan Beg, your guest host of the podcast today. I'm an adjunct associate professor at UT Southwestern's Simmons Comprehensive Cancer Center and vice president of oncology at Science 37. Today, we'll be discussing key abstracts and other exciting highlights from the 2024 ASCO Gastrointestinal Cancers Symposium. Joining me to discuss some key takeaways from the meeting is the chair of this year's Symposium, Dr. Rachna Shroff. Dr. Shroff is the division chief of Hematology Oncology and chief of GI Medical Oncology at the University of Arizona Cancer Center. She also serves as the associate dean for clinical and translational research at the University of Arizona College of Medicine – Tucson. Our full disclosures are available in the transcript of this episode, and disclosures related to all episodes of the podcast are available at asco.org/DNpod.  Dr. Shroff, welcome back to the ASCO Daily News Podcast, and congratulations on a great Symposium. The scientific advances and innovative, multidisciplinary approaches that were featured throughout the meeting were really inspiring and reflect the incredible strides we're making in GI cancer research. Dr. Rachna Shroff: Thank you so much for having me back. I am delighted to be here.  Dr. Shaalan Beg: Dr. Shroff, the theme of this year's symposium was "Taking Personalized Care to the Next Level." I'd love to hear your reflections on the sessions that you found most exciting and really resonated with the attendees.  Dr. Rachna Shroff: Yes, thank you. We were really excited about this theme because we really felt that “Taking Personalized Care to the Next Level” translated to thinking through personalized approaches to patient care, not just in the traditional ways that we think of with precision oncology and genomics driving our care, but also how we can think through multidisciplinary approaches and an individualized care plan. Thinking through how artificial intelligence and novel clinical trial designs can and should be implemented to meet the needs of our individual patients. And so we really highlighted that in what was a somewhat new reboot of a session called “Intersections,” which were every day and were really more cross-tumor; they were tumor agnostic but were thematic focused. As I mentioned, those themes were really based on feedback that we had from prior attendees, as well as from the program committee's feeling on what are really the questions that we are dealing with and that are burning in the clinic today and that includes the emerging role of artificial intelligence and machine learning and how we integrate that into our clinical care, approaches to oligometastatic disease, and it's not really just something that we think of in colorectal cancer but haven't fully used that paradigm to really apply it to other GI malignancies. And then the art and science of clinical trial design where, again, traditional randomized phase 3 trials might not be the best and most innovative and most expedient way of bringing novel therapeutics to our patients. And so, I thought that all of those sessions were really highlighting different important topics that we deal with day to day. Additionally, we had a really fantastic keynote lecture from Dr. Kimmie Ng of the Dana-Farber Cancer Institute. She is a world-renowned expert in the early-onset colorectal cancer space, and the timing of her keynote was perfect with the new cancer statistics that came out literally days before GI ASCO that demonstrated this just dramatic rise in early onset GI malignancies as a whole, not just colorectal. And she spoke really in a comprehensive manner not just on clinical approaches, screening approaches, and how to find these patients at an earlier stage, but also kind of gave us a call to action, if you will, in terms of public health initiatives, as well as like I said, clinical care and really thinking outside of the box for how to reach these patients.  And then, of course, we always have what I think is one of my favorite aspects of the meeting, which are the networking opportunities that include the Trainee and Early Career Networking Luncheon, the Women's Networking Reception, and the Meet the Experts Luncheon where, especially as junior career investigators, you have an opportunity to meet what we think of as the “big names” in GI cancer. Dr. Shaalan Beg: Absolutely, I remember my first couple of GI ASCO meetings and those were probably the most memorable sessions that I attended as junior faculty as well.   So let's take a deeper dive into some key abstracts from the meeting. I'd like to begin with Abstract 245. This is the SKYSCRAPER-08 study. It's first-line tiragolumab and atezolizumab with chemotherapy in an Asian patient population with esophageal squamous cell carcinoma. What are your key takeaways from this study?  Dr. Rachna Shroff: Yeah. This was an exciting study in my opinion in the sense that thinking through how we can build on immunotherapy backbones is obviously a pressing question across the GI cancer space. So this was a phase 3 randomized, double-blinded, placebo-controlled trial that looked specifically at patients with esophageal squamous cell carcinomas. And the study was enrolled fully with an Asian population. It looked at taking the traditional chemotherapy backbone and adding to it an anti-PD-L1 with atezolizumab and an anti-TIGIT with tiragolumab. Again, that proof of principle of using anti-TIGIT and PD-L1 has been looked at across a lot of different GI cancer spaces and we know that the esophageal squamous cell cancers tend to be very immunotherapy responsive. So this was a really important question.  This involved a number of patients, a little over 460 patients, who were randomized one-to-one to receive the tiragolumab with atezolizumab with the standard paclitaxel and cisplatin, that's used for esophageal squamous versus chemotherapy alone with placebo. And the primary endpoint was independent review of progression-free survival, and overall survival. And so, out of the 461 patients randomized, there was at the primary analysis, a median improvement in progression free survival, from 5.4 months in the control arm to 6.2 months with a tira-paclitaxel plus chemo arm with a hazard ratio of 0.56, highly statistically significant. Similarly the median overall survival was also improved from 11.1 months to 15.7 months again with a hazard ratio of 0.7 and some of the other key efficacy endpoints were also improved with the addition of the anti-TIGIT PD-L1 approach. And importantly, there was not really safety signals that jumped out at us.  And so, to me, what this means is that, in our patients with esophageal squamous cell carcinoma, we really should be thinking about chemotherapy with immunotherapy as a backbone and how we can build on it. And, you know, I would imagine that it's hard to argue with both the PFS and OS endpoint that adding anti-TIGIT won't necessarily be kind of the new approach to these patients. And importantly, I'll point out that it seems to be a benefit across the subgroups, including PD-1 status, which is always our big question here. I think the only thing to keep in mind is this was an all-Asian population and whether or not that kind of immune profile of the immune responsiveness is different in those patients, but regardless, a positive phase 3 trial. Dr. Shaalan Beg: It's really exciting to see immune checkpoint inhibitors or immunotherapy beyond PD-1 targeted, CTLA-4 targeted treatments making their way into GI Cancers.  Dr. Rachna Shroff: Absolutely. Dr. Shaalan Beg: Sticking with the immunotherapy theme, let's focus on hepatocellular carcinoma. So LBA432, the EMERALD-1 study of transarterial chemoembolization combined with durva with or without bevacizumab looked at people with unresectable hepatocellular carcinoma eligible for embolization. So really a highly anticipated study, I'm wondering what your thoughts are and whether it'll be practice-changing for this field.  Dr. Rachna Shroff: I was excited to see the press release when it showed that the study was positive, and I think it's because now that we're using immunotherapy in the advanced HCC space, our obvious question is, can we integrate it into multimodality approaches? There are a lot of smaller studies looking at neoadjuvant IO approaches, and in this intermediate stage, unresectable hepatocellular carcinoma patients. We wanted to know if there was a utility to liver directed therapy with immunotherapy.  So, this was a large study. It was a global study looking at unresectable HCC with preserved Child-Pugh function. But it was Child-Pugh A and up to B7, importantly. And there were 616 patients randomized in a 1:1:1 fashion, with the control arm being just TACE alone. But then, there was also an opportunity for durvalumab with TACE, as well as durvalumab plus bevacizumab with TACE. The patients would receive durvalumab during their TACE treatments and could receive up to four TACE treatments and then subsequently were either continued on durvalumab alone, durvalumab plus bevacizumab, or the placebo. The primary endpoint was progression-free survival, powered specifically to look at TACE versus durvalumab plus TACE. In this study, the primary endpoint was met with a significant improvement in PFS. Median PFS was 15 months versus 8.2 months, with a hazard ratio of 0.77. Most prespecified subgroups demonstrated this benefit.  Importantly, there was a secondary endpoint looking at durvalumab plus TACE versus TACE alone, and that actually did not show a statistically significant improvement in median PFS from 8.2 months in the control arm to 10.0 months. The overall response rates were slightly higher with the durvalumab plus bevacizumab approach at 43.6%. And importantly in these patients, who oftentimes have a higher burden of disease in the liver, median time to progression is a really important and clinically meaningful endpoint. That was 22 months with the durvalumab plus bevacizumab and TACE versus 10 months for TACE alone. I would just point out that the overall concern we always have with bevacizumab is the increased risk of bleeding and the treatment-related adverse event profile. Overall, there were no safety signals that emerged from this, with nothing that really, especially in that bleeding risk category, jumped out at us. Of course, we haven't seen the overall survival data yet because we have not seen enough follow-up to really see that number.  I do think that this is potentially practice-changing, and I think it just demonstrates that there's probably some synergy between anti-VEGF with anti-PD-1, and then the liver-directed treatments. The obvious question for us in the United States is that the vast majority of people are moving away from TACE and towards more radioembolization and what can we extrapolate from this? Does this really tell us much if people are using more of a Y90-based approach? I think those are a lot of the burning questions that most of us have.  Dr. Shaalan Beg: Yeah, and it's a very interesting direction that the HCC space is taking because we heard in previous meetings, the role of PD-1 inhibition as adjuvant therapy after resection. Now, we have data for local-regionally advanced disease over local-regional treatments. And of course, you already mentioned the data for more advanced disease. So it sounds like immunotherapy may be impacting the management of anyone diagnosed with hepatocellular carcinoma.  Let's talk about the MONET trial, Abstract 249, which compared thoracoscopic esophagectomy and open esophagectomy for thoracic esophageal cancer. Do you think this is a study which may influence the treatment of patients with thoracic esophageal cancer? Dr. Rachna Shroff: So, this was, again, I think, a really important question. It was a randomized, controlled phase 3 trial comparing a more minimally invasive approach with TE — thoracoscopic esophagectomy — versus an open approach. This had patients with clinical stage 1-3, excluding T4 thoracic esophageal squamous cell carcinomas. They were randomized 1:1 to the open versus the TE approach, with a primary endpoint of overall survival and an important secondary endpoint of relapse-free survival. 300 patients were randomized, and at the second planned interim analysis, the median follow-up was a little over two and a half years. The 3-year overall survival was 82% in the TE group versus 70.9% in the open group. The DSMC of this trial actually recommended early termination based on the non-inferiority, which is what they were specifically looking at. There was a very statistically significant one-sided p-value for non-inferiority.  Importantly, the 3-year recurrence-free survival was also markedly better in the TE group versus the open group, with no real notable differences in R0 resection, or a large percentage of patients who needed to be converted from a TE to an open approach, and really not any significant difference in overall postoperative morbidity. I think this just supports the concept that minimally invasive approaches for our patients with GI malignancies can and should be considered. Again, esophageal squamous because they tend to be seen a lot more in Asia, this study was conducted in Japan, but I think that being said, a lot of our surgeons in Europe and in the U.S. are also very amenable to minimally invasive approaches. And I think this just supports the fact that an open approach is not necessary. So, I would think again, that this is something that is implementable and I think will affect the field.  Dr. Shaalan Beg: Moving on to metastatic cholangiocarcinoma, there have been many FGFR inhibitors that have shown activity and promise and are approved for the management of cholangiocarcinoma with FGFR alteration. But at this ASCO GI, we heard the results of the safety and efficacy of an FGFR1, 2, and 3 inhibitor, tinengotinib, as monotherapy for advanced metastatic cholangiocarcinoma (Abstract 434). How do you see this fitting into the broad picture? Dr. Rachna Shroff: Yeah, so this was highly anticipated data, primarily because at this point, the FGFR space in cholangiocarcinoma is quite crowded. And so a lot of us were getting sick of the "me-too" drugs. What is really unique about tinengotinib is that, not only is it a selective multikinase inhibitor, but it also, in preclinical models as well as in early phase one trials, demonstrated potent inhibition of patients with FGFR2 fusions and rearrangements who had acquired resistance mutations. So, as we better understand the first generation of FGFR inhibitors and note the resistance mechanisms, these drugs are now being developed to try to circumvent or overcome those.  This study looked at 4 different cohorts: 1 cohort with FGFR2 fusion patients who had primary progression who never responded to FGFR inhibitors, a second cohort with FGFR2 fusion patients who had progression after primary response, so those with acquired resistance, and then there was non-fusion FGFR alterations because we do know that a number of cholangiocarcinoma patients have other FGFR alterations that are not fusions, and then those with FGFR wild-type. The primary endpoint was objective response rate, with a total of 48 patients enrolled across the four cohorts. And so the 40 patients who were evaluable in the group that had primary resistance, which was the first cohort, there was a response rate was 9.1% and that was partial response, and 31% had tumor reduction with tinengotinib. And similarly in those with acquired resistance, 37.5%, 3 out of 8 patients had a partial response and tumor reductions were noted with an overall disease control rate between those patients with FGFR2 fusions of 94.7%, between those with primary and secondary resistance.  In the patients who had FGFR alterations, there was 3 out of 9 patients with a partial response and again, tumor reductions were notable across the board and the disease control rate was 88.9%. The FGFR wild-type group, not surprisingly, did not see any partial responses, but interestingly, 75% of these patients had at least disease control, and the median progression-free survival was 5.26 months, again, kind of most notably impressive in the 2 cohorts that included FGFR2 fusions. The toxicity profiles are what we come to expect for FGFR inhibitors and we've gotten better at managing those and mitigating some of those so there was really nothing to jump out there. So there is now an ongoing randomized phase III trial specifically looking at tinengotinib versus physician's choice in patients with FGFR2-altered cholangiocarcinoma after having received prior FGFR inhibitors. So that's where I think it's in is for those of us who know that there are multiple drugs in the space, our big question is can we sequence through that? Can we offer multiple FGFR inhibitors in these patients? And I think we are all eagerly anticipating this data as well as the subsequent data to really justify the use of these novel second generation FGFR inhibitors.  Dr. Shaalan Beg: It's been fantastic to see the evolution of these compounds in precision medicine, or precision oncology at its finest, in terms of understanding mechanisms of resistance and treating refractory disease.   Let's focus on colorectal cancer. I'll tell you, there has been a lot of discussion, Dr. Shroff, on social media, on insurance companies sometimes rejecting one biologic or the other based on tumor sidedness. We have talked about tumor sidedness predicting response on this podcast based on data from previous studies. But this year in GI ASCO, Abstract 207 explored the role of tumor genomics and tumor sidedness and they said that it's tumor genomics, that tumor genomics better explains the differences on outcomes, and it explains it better than sidedness. What does this mean to the field? Because a lot of professional organizations have guidelines that are asking people to now incorporate sidedness. So how does that change based on these results? Dr. Rachna Shroff: I really commend these authors on leveraging real-world data, and I think we're getting better and better at recognizing that real world data actually informs our clinical decision making, possibly better than sometimes some of these studies that lead to the guidelines and algorithms that we develop. So this is a perfect example of a little bit cart before horse in trying to understand the way that sidedness and genomics may interplay.   So this was a study that basically leveraged both the Foundation Medicine and Flatiron Health clinical genomic database and looked at patients with microsatellite stable metastatic colorectal cancer. There were a total of 3,845 patients included in a kind of two-thirds one-third split between left sided and right-sided colorectal cancer. And they found the typical genomic alterations that historically have been thought of more with left-sided colorectal cancer like APC and then more of the RAS BRAF alterations in the right-sided patients. But I think what they really thought and what I think was remarkable is they really looked at the patients and how they received chemotherapy with anti-EGFR or bevacizumab therapies, and they did a multivariate analysis to really see what is driving outcomes. And like you mentioned, what they found was patients in the RAS pathway, those classified as having alterations in the RAS pathway, had less favorable outcomes, while those with APC altered group had more favorable outcomes. And that was regardless of treatment received and sidedness.  And so when they did an analysis of what was called a “likelihood ratio test,” they found that when genomics was added to the sidedness evaluation, there was an improvement in outcome prediction, but not when sidedness was added to genomics. Like you said, it kind of demonstrates, at least in this mining of real-world data from Flatiron that tumor genomics is probably a better driver and a more important driver in determining outcomes than sidedness.  I totally agree with you. I would push for us to really kind of bring a little bit of noise to this and to make insurance companies and other companies that are looking at this to think through this a little bit more and make sure that we're putting all of the data together in a comprehensive passion before making the treatment plans and determinations. Dr. Shaalan Beg: The last abstract I'd like to ask you about is Abstract 117, the NEST-1 trial. This study looked at neoadjuvant botensilimab and balstilimab for resectable mismatch repair proficient and deficient colorectal cancer, both MSS and MSI. What are your key takeaways from this study?  Dr. Rachna Shroff: This is another study that is demonstrating that there may potentially be a role for immunotherapy in microsatellite stable patients. I will make the caveat that this was a single-arm study that really was looking at feasibility safety, with efficacy as a secondary endpoint. The combination of bot-bal in the neoadjuvant space for colorectal cancer patients, they received one dose of boten and two fixed doses of bal two weeks apart and then were taken to surgery. They limited the number of patients and out of the 12 patients that were enrolled, they limited the number of mismatch repair deficient patients. So to your point, they allowed both, but they wanted to make sure it was not just MSI-high patients. What they basically found is that it was safe and did not delay surgery or increase risks of adverse events. But importantly, there was significant regression of tumor noted. And some interesting spatial biology analyses demonstrated potentially novel mechanisms of action, especially in the MSS population, and that ctDNA reductions correlated with pathologic response. There were a lot of different things that they were looking at, basically suggesting that bot-bal is safe and can be used in both mismatch repair–deficient and proficient patients with colorectal cancer. And now importantly, they've added some additional cohorts and expanding the study. As I mentioned, this is right now just 12 patients, but does definitely have a provocative result.  Dr. Shaalan Beg: Thanks so much, Dr. Shroff.  Finally, the role of cell-free DNA (cfDNA) in GI cancers has been an exciting and important development in our field. There's tremendous data that emerged at the GI meeting, and we have decided to do a separate ASCO Daily News Podcast dedicated to ctDNA. So listeners, please look out for our coverage of key studies on ctDNA in GI cancers very soon here on the ASCO Daily News Podcast.  Many thanks, Dr. Shroff, for sharing your insights with us today and for your great work in building a robust GI meeting this year. Thank you very much. Dr. Rachna Shroff: Thank you so much. Dr. Shaalan Beg: And thank you to all our listeners for your time today.

Dr. Mohamed Salem, Dr. Myriam Chalabi, and Dr. Andrea Cercek discuss pivotal neoadjuvant immunotherapy clinical trials for patients with MSI-H/dMMR colorectal cancer, focusing on the development of active therapies in the neoadjuvant setting—where patients are treated without surgery, radiation, or chemotherapy—and the importance of patient selection in finding the right target and treatment to improve outcomes. TRANSCRIPT Dr. Mohamed Salem: Hello, and welcome to the ASCO Daily News Podcast. I'm your guest host today, Dr. Mohamed Salem. I'm a GI oncologist at the Levine Cancer Institute at Atrium Health. Today, we will be discussing very promising advancements in the neoadjuvant immunotherapy for patients with MSI-H/dMMR colorectal cancer. And I'm very delighted to welcome two world-renowned oncologists whose research has tremendously helped shape the treatment landscape of colorectal cancer. Dr. Myriam Chalabi is a GI medical oncologist at the Netherlands Cancer Institute, and Dr. Andrea Cercek is a medical oncologist at Memorial Sloan Kettering in the United States.  Our full disclosures are available in the transcript of this episode, and disclosures relating to all episodes of the podcast are available on our transcripts at asco.org/DNpod.  Dr. Chalabi and Dr. Cercek, welcome to the ASCO Daily News Podcast. Dr. Myriam Chalabi: Thank you for having me. Dr. Andrea Cercek: Thank you very much for having me. Dr. Mohamed Salem: It's a pleasure to have two world-renowned stars like you. Thank you for taking the time.  So, before we start going deep into the topic, obviously, now we are seeing emerging data in CRC using immunotherapy as the neoadjuvant approach, which actually can reduce or even eliminate some of the other treatment modalities and potentially save patients from toxicities. Both of you led what I think are landmark studies in this field. I wanted to give you the chance to tell our audience about your studies and why you think they're important. Dr. Cercek? Dr. Andrea Cercek: Sure. Thank you so much. So, our study was a neoadjuvant study in early-stage, locally advanced rectal cancer with tumors that were mismatch repair-deficient or MSI-H. And rectal cancer normally is treated with chemotherapy, chemoradiation, and surgery. And the goal of the trial was to utilize PD-1 blockade alone in this subpopulation and evaluate the response.  Patients received six months of dostarlimab, which is a PD-1 blocking agent, and then were evaluated for response. If there was no residual disease, they were able to avoid radiation and surgery. And what we've seen thus far in the presentation at GI ASCO in 2022 was that all patients who received six months of dostarlimab had a clinical complete response, so no residual tumor, and were able to avoid chemotherapy, radiation, and surgery and are on observation. And the study is ongoing and actively accruing patients. Dr. Mohamed Salem: All of us were very excited seeing that presentation at ASCO. And when we came back to the clinic everyone was talking about it, including patients, obviously. Thank you for this, Dr. Cercek. Dr. Chalabi, you also led a similar study that was actually presented in ESMO in 2022. Can you please give us, like, a brief description of that trial? Dr. Myriam Chalabi: Yeah, sure. So, this is the NICHE trial, and actually the NICHE trial has been ongoing for quite some time now. We recently presented a larger NICHE-2 study, but basically– so what we started out by doing in NICHE is giving patients what we considered back then a window of opportunity study. We treated patients with MMR-deficient tumors, which I'll be focusing on for now, with two cycles of nivolumab and one single cycle of low-dose ipilimumab. And patients all undergo surgery within six weeks of registration within the study. And back in 2020, we published the first data of NICHE-1 showing 100% pathologic responses with 60% pathologic complete responses and decided that this should definitely be a treatment that we need to explore in a larger group of patients. And that's where NICHE-2 was born, which we presented at ESMO last year, where we treated over 100 patients with this neoadjuvant approach of two cycles nivolumab, one single cycle ipilimumab, showing 99% pathologic responses, including 95% major pathologic responses and 67% pathologic complete responses. And this was all within five and a half weeks of the first treatment with immunotherapy, so a very short treatment duration with dual checkpoint blockade. Dr. Mohamed Salem: Amazing results, too. And I know you had a standing ovation when you presented the outcome of the study. And again, congratulations to you, your investigator, and also all the patients participated. Dr. Myriam Chalabi: Thank you so much.  Dr. Mohamed Salem: I guess the first question that comes to my mind - we have two trials, obviously, now we're moving from one size fits all to precision therapy, like getting actually the right treatment for the right patient. But in the NICHE study, it was a checkpoint inhibitor, and the rectal study was a single agent. I want to start with you, Dr. Chalabi. In your opinion, when should we use single agent or double blockade immunotherapy? Dr. Myriam Chalabi: That is a great question. I'm going to start off by saying that I don't know the exact answer. I don't think we know that answer. And Dr. Cercek is going to share also her thoughts on this because we're seeing, of course, fantastic responses with monotherapy as well in Dr. Cercek's study. And we've also seen that in a study by Dr. Overman with monotherapy. So that may suffice in some patients, although what we're seeing is that you need to treat patients longer, probably to achieve that response, at least clinically. And I think that is the difference with dual checkpoint blockade, that we're giving in NICHE where we're seeing these very deep responses in just under six weeks' time.  So, I think it may be more of a question of how long we want to treat patients for to achieve the endpoint that we're aiming for. And, of course, there may be, at some point, patients that need dual checkpoint blockade, but so far, we're seeing great responses in both of our studies. So I think we need more patients, more data to see whether we're going to see non-responders. And hopefully, the studies that are ongoing in the metastatic disease setting will give us at least a little bit of insight into what the differences are in response to mono and dual checkpoint blockade and whether we can tell which patients might benefit more from the combination. But I think there's still a lot of work to be done in that field. Dr. Mohamed Salem: I totally agree. Dr. Cercek, same question to you. What do you think?  Dr. Andrea Cercek: Dr. Chalabi answered beautifully and very comprehensively. I agree completely with what she said. It's hard to argue with the responses that we're seeing with PD-1 blockade alone. But then again, dual checkpoint inhibitors in the NICHE study with just one month of therapy had phenomenal responses as well. So I think it's a question of duration of therapy and, really importantly, what we're trying to achieve. If our goal is organ preservation, then perhaps longer duration is better. The question then becomes, can we do, should we do longer duration with dual checkpoint inhibitors versus single agent? So I think, as she concluded, I couldn't agree more that we just need more information, we need more work to do, basically to answer this question for our patients. Dr. Mohamed Salem: More to come and more studies, which is fascinating.  So, Dr. Chalabi, you created actually a new term on Twitter called ‘Chalabi Plot'. It was amazing to see such a response. But we're curious, among those patients who achieved complete response so far, did you see any relapse? Dr. Myriam Chalabi: Short answer, no.  we're waiting, of course on the disease-free survival data, the three-year DFS data for NICHE-2, and we hope to have that by the end of this year, beginning of next year. But as of now, we showed that data, and so far, we haven't seen any recurrences in, actually, any of the patients treated in NICHE-2. Dr. Mohamed Salem: Fantastic. Dr. Cercek. So I think your slide -- I remember clearly from the ASCO presentation -- was all complete response, every single patient.  Same question, did you see any relapse so far? Dr. Andrea Cercek: So far, no, we have not. Dr. Mohamed Salem: Amazing. So, Dr. Cercek, as you know, and obviously, this is metastatic disease, but in KEYNOTE-177, as you know, about 30% of patients with MSI-high tumors did not respond to checkpoint inhibitors. So that makes some of us feel nervous about using checkpoint inhibitors alone in colorectal cancer, even with MSI-high status. I was curious if you can comment on this and if there is a way we can perhaps sort out who actually is likely to respond and who is likely not going to respond. Dr. Andrea Cercek: I think that's a really important question and an excellent point. And we believe that the difference lies in the fact that in KEYNOTE-177, the patients had metastatic disease, whereas in our neoadjuvant studies that we're discussing, they have early-stage disease. And whether that has to do with the tumor differences, young tumors versus older tumors once they become metastatic, or the microenvironment, remains to be determined. But certainly, there is this pattern of incredible responses with checkpoint inhibitors in early-stage dMMR tumors. And in KEYNOTE-177, as you mentioned, about 30% of patients progressed. And I think we don't know why that is. We are seeing this, about a third of progressors repeatedly in the metastatic setting with checkpoint inhibitors. And so perhaps there is a population. But whether this is driven by genomics or something else, we don't know. Dr. Mohamed Salem: Great. So, along the same lines, especially rectal cancer, obviously, because surgical resection is a key component in the treatment paradigm, do you feel patients who achieve pathological complete response should still go under surgical resection or should go under the ‘watch and wait' approach? Dr. Andrea Cercek: In general, I'm a fan of organ preservation. I think in rectal cancer, the reasons are obvious. It's a challenging surgery. It's very toxic to the patients. It changes their lives forever. In survivorship, 30% of them require a permanent colostomy because of the location of the tumor. So there, the field of rectal cancer, in general, is moving towards non-operative management, even in the MSI-proficient patients, by trying to optimize therapy to increase clinical complete responses and therefore omit surgery. So that's the difference with rectal cancer. In colon cancer, it's a different discussion. I think for many patients, surgery is very straightforward. It's a hemicolectomy. It doesn't alter lifestyle in survivorship, so it's not as morbid as it is in rectal cancer. Of course, I think if a patient is older with MSI-deficient tumor perhaps can undergo surgery, then clinical complete responses become critical because then we can monitor them after just checkpoint blockade, and they don't need surgery.  The challenge there, and I would love to hear Dr. Chalabi's comments on this, too, is just that imaging is challenging. We have a hard time in colon cancer determining whether someone has a clinical complete response or not. It seems to be very different than in rectal cancer, where with endoscopy and with the rectal MRI, we really can't tell whether the tumor is still present or not. This remains a challenge in colon cancer. Dr. Mohamed Salem: Dr. Chalabi, I would like to hear your thoughts and also how you practice in Europe. I don't know if it's the same like here in US or different. Dr. Myriam Chalabi: I completely agree with Dr. Cercek. Well, if we look at the rectal cancer patients, I think this is fantastic. That even though this is a small population achieving this high clinical complete response rate, not having to operate or even give any chemotherapy or radiation therapy to these patients, it is extremely important both in the short term but also in terms of long-term complications and morbidity. When it comes to the colon cancer responses that we're seeing in NICHE, those are all pathologic responses, of course. And we have been evaluating also preoperatively using scans to see whether we can assess these complete responses based on imaging. That doesn't seem to be the case. We do see responses in all patients, so we see these are all very large bulky tumors that we're treating in NICHE-2. And we do see responses in almost all of these patients, but it's not close to complete responses, definitely not in all of the complete responders that we're seeing. So that makes it difficult.  And the question is, what if we would be waiting or treating longer because these bulky tumors need more time to disappear or to be cleared before you're going to see it on the imaging? So that is a question that I don't have an answer to just yet. We may be getting some more data on that with the currently ongoing trials. And as Dr. Cercek pointed out, the endoscopies when you have a right-sided colon tumor are different than doing just a sigmoidoscopy for a rectal tumor. So, we actually do have one patient who hasn't undergone surgery, and that is actually a patient with an MMR-proficient tumor within the NICHE trial who had a complete response. And that patient has a sigmoidal tumor, and he actually had toxicities which prevented him from undergoing timely surgery and now has a complete response after two years, both endoscopically and on imaging. So, he hasn't undergone surgery, and that is a great example of how we may be doing this in the future. It's an interesting case within the trial to follow and see how we can do it in the future. Dr. Mohamed Salem: That's fascinating news. So, was it MMR-proficient? Dr. Myriam Chalabi: Yes, this is an MMR-proficient tumor.  Dr. Mohamed Salem Wow. Any particular biomarkers that you think he or she had to predict that? Dr. Myriam Chalabi: We have treated more patients with MMR-proficient tumors. We have 31 patients, and we have seen actually responses in 9 out of 31 patients in the MMR-proficient tumors with the same combination of two doses of nivolumab and one of ipilimumab. We previously published on half of the cohort approximately on what the possible predictive biomarkers of response could be, and that was a costimulation for CD8 and PD-1. So PD-1 positive CD8 T cells. And we're currently doing the same work for the rest of the cohort. So hopefully, we'll be able to show that soon and see whether this still stands for the completed MMR-proficient cohort. But definitely also very exciting data for the MMR-proficient. Dr. Mohamed Salem: So, this is actually a very good segue to my next question because I know all of us are looking for this. Like, obviously, we're seeing a fascinating response in those patients with MSI-high tumors, but majority of colorectal cancer, as you know, they actually have MSS-proficient tumors. Any thoughts about how we can overcome the primary resistance for this tumor to checkpoint inhibitors? So let me start with you, Dr. Cercek.  Dr. Andrea Cercek: I'm very much looking forward to Dr. Chalabi's data on this because, honestly, we have not seen such amazing responses to immunotherapy in MSS tumors. The initial studies were complete flatline, no responses at all. And here, she just described a patient that had a complete response to just a month of checkpoint inhibitors. So that's phenomenal, and hopefully, we'll learn from the responders.  We believe that there is a subpopulation of MSS colorectal cancer that is more immune sensitive, immune hot, whichever term you like to use. And it's just a matter of appropriately identifying those patients. And personally, I think the answer lies in the neoadjuvant setting in early tumors where they're treatment-naive, not exposed to chemo, not exposed to radiation, younger, have their innate microenvironment. And so, I think it's likely a combination of the above. But obviously, the ultimate goal is to find out who those patients are and then potentially treat them just like this with immunotherapy. And that would be another nice chunk of the pie where we could utilize immunotherapy for our patients. Dr. Mohamed Salem: Very true. Dr. Chalabi, especially with your experience and just showing there is a chance for those people to respond, what are your thoughts about how we can overcome this primary resistance? Dr. Myriam Chalabi: It's great to be here with Dr. Cercek because, obviously, we have very similar interests but it's also good to see that we think the same way because I completely agree with what she just said in terms of neoadjuvant. I think that was one of the most important things that we did here, giving this neoadjuvant treatment in non-metastatic tumors. It's probably a very important driver in the responses that we're seeing. So, we've been seeing data now a bit more in the metastatic disease setting where MSS tumors seem to be responding to new generations of checkpoint blockade. And the question is how those would do in the neoadjuvant setting that would be even different than what we're seeing now. But there's definitely some proof of MSS tumors that can respond to immunotherapy. The question on how to overcome the primary resistance, I think that question is for us: Who are the patients with primary resistant tumors and why are they primarily resistant? And then we can think about how to change that and how to change them into the tumors that are responding. I think these types of data will be key to understand more and know; hopefully, even you said, in the metastatic disease setting, to make these tumors more pliable in response to immunotherapy. Dr. Mohamed Salem: I agree. So, both of you are leading us toward how to choose the right patient with the right target for the right treatment. That's an amazing journey you're taking all of us on.  So, Dr. Cercek, I have to admit that with your data, it created some problems for us in the clinic because all patients the following day came in asking for immunotherapy. We had a hard time trying to explain that maybe this is not the right treatment for them or, like, not the right platform. But I wanted to ask you, if we'll have a patient tomorrow in the clinic with localized rectal cancer and happen to have an MSI-high tumor, what would be your recommendation in terms of how to approach that patient? Dr. Andrea Cercek: I think, ideally, you would discuss clinical trials with the patient. We have opened the study now to not just rectal cancer but colon cancer and, in fact, all solid tumors that are mismatch repair-deficient. So I think at this time, the patients really should be treated on a clinical trial. As we learn more, in particular, until we are more comfortable assessing for a clinical complete response and follow-up. I think the surveillance piece will be critically important. In rectal cancer, it's well established, but it's not in the other tumor types. So my recommendation would be to enroll the patient on a trial. Dr. Mohamed Salem: Just to add to that too, obviously, as you know, there is now the cooperative group trial that's looking at that option and we obviously encourage all centers to participate and open that study to have this option for our patients. Dr. Chalabi, so what do you guys do in Europe for these patients? Dr. Myriam Chalabi: In Europe, it's a very different situation. I would have answered this question differently by saying, well, we don't have that option of treating patients outside of clinical trials. So basically, we have to make sure that we have clinical trials for these patients. And that's something that we've had for colon cancer patients. That is still the case. And we're getting rectal cancer trials also for patients with MMR deficient tumors and have those also for MMR proficient tumors. For us and I agree completely that we should be treating patients within clinical trials, we don't have another option. But still, even if we did, I think it's important to create data within clinical trials to be able to ultimately also show why this should be standard of care and how we can make it standard of care. Because if you're not accumulating that data, then it's going to become very difficult if accrual is lacking. Now, we treat patients either with standard-of-care treatments, but usually, we try to find something within clinical trials.  Dr. Mohamed Salem: I totally agree. And as we always say, the standard of care should be a clinical trial participation. So, I must say, both of you, Dr. Cercek and Dr. Chalabi, you made 2022 a very exciting year for us in GI cancers. You really changed the way we look at how to treat these patients and give them a huge chance of, I would say, actually cure and obviously organ preservation. So, I'm very curious to know what you are both are working on now and what we should expect in 2023 and 2024.  Dr. Andrea Cercek: So, for me, the study is ongoing, as I mentioned, and we've expanded to all mismatch repair-deficient solid tumors with the same approach of six months of dostarlimab and then the option of nonoperative management. And I think that it'll be important for us to learn in terms of responses on the luminal versus some of the other tumor types, like, for example, pancreas cancer, where we don't see these robust responses in the metastatic setting, that will be important to do. We're doing some correlative analysis, as Dr. Chalabi described as well in our patients.  And then, I'm interested in optimizing neoadjuvant approaches to minimize therapy in rectal cancer specifically. So, we have a study now for HER-2 amplified RAS wild-type patients with locally advanced rectal cancer with a similar approach of utilizing HER-2 targeted therapy first and then in combination with chemotherapy. In our case, it's a combination of trastuzumab and tucatinib and then chemotherapy with CAPOX and assessing for response and potential omission of radiation and surgery depending on responders. So, I'm very excited that study is open and actively accruing, and hopefully, we can get similar responses that we did in the MSI population with PD-1 blockade. Dr. Mohamed Salem: Is that only available at MSK? Dr. Andrea Cercek: It is at this time. However, we will likely be expanding, so if there's any interest, let me know. Dr. Mohamed Salem: Great. I'm sure many centers will be. Great. What about you, Dr. Chalabi? Any sneak peek in the future? Dr. Myriam Chalabi: So many sneak peeks, where to begin? I think it's very exciting to be working in this space at this time, and we're very lucky to be in it. So, for NICHE, we're actually accruing now in new cohorts for both MMR-deficient and MMR-proficient tumors. For the patients with MMR-deficient tumors, we're actually testing a new combination of nivolumab plus relatlimab, so anti-LAG-3 plus anti-PD1. And we're testing the same co-formulation in patients with pMMR tumors. In addition to another cohort for the pMMR tumors with nivolumab, all within this window of opportunity, as we did previously in NICHE, and to see if we're going to see more responses if these are going to be different tumors than the ones responding to nivolumab and ipilimumab. And for the MMR deficient tumors, we're treating longer with this combination now. So, we're operating after eight weeks instead of six weeks. We're giving two cycles, four weekly cycles, to see whether we can even improve the PCR rates, even though this is, of course, a different combination treatment. So, very exciting times for NICHE, and we'll have the readout for the DFS at the end of this year, so that's also very exciting. And then, well, it's similar to Dr. Cercek. So again, we're on the same page when it comes to these neoadjuvant treatments. We have actually an ongoing trial for neoadjuvant treatment of patients with MMR proficient rectal cancers, and that is using a combination of radiation therapy followed by a combination of atezolizumab or anti-PDL1 with Bevacizumab with the aim of organ sparing approach in these patients. And we actually presented stage 1 of this trial as a poster at ASCO GI, showing that we achieved 56% complete or near complete responses clinically at 12 weeks. And after at least a year of follow-up for all patients, we have 50% organ preservation. So those are very exciting data as well. Also, in the MMR proficient tumors, I'm very excited to hear about the HER-2-positive tumors and Dr. Cercek's study. So there's definitely a lot going on that we hope to share as soon as the data are available. Dr. Mohamed Salem: We'll be looking forward to your next presentation and seeing that. So again, most of your work showed us that we really have to choose the right patient with the right target for the right treatment to achieve the best possible outcome. So we're getting short on time here. But before we conclude, ASCO Daily News Podcast has a huge audience of oncologists, I wanted to give you the chance to share anything you'd like to share with our audience today before we finish. Dr. Cercek? Dr. Andrea Cercek: I believe this is an incredibly exciting time in colorectal cancer. I think it's finally our turn, which feels really nice, and obviously, we have a lot more work that needs to be done. But my personal belief is to keep trying to chip away at the pie and identify responders and keep working to have better-targeted drugs and better treatment options that will improve responses and improve outcomes for our patients. But I certainly believe that we are well on our way there, and it's very exciting. Dr. Mohamed Salem: I totally agree. Dr. Chalabi, any thoughts? Dr. Myriam Chalabi: I think after 2022 and the data that we've been showing, I think it's important to– and I think by now, maybe it's not even necessary anymore to say it– but I think it's important to really look at the tumors and look at these MMR proteins or MSI, and to make sure that you're treating the patient in the right way, and to consider that. Before, it wasn't as important in the neoadjuvant setting or these localized tumors, but now it's becoming essential.  And I think if you would have looked five years ago and you would say, yeah, these MSI tumors are important to find, it's a very small proportion of patients, in rectal cancer even lower than in colon cancer. But still, it has such a huge impact on what you're doing in these patients and your chances of cure. So I think that would be my most important giveaway to test for MMR deficiency before deciding on a treatment for your patients. And we're working on trials with neoadjuvant immunotherapy. Also in other tumor types, Dr. Cercek is also doing the same. I think those will be very important also outside of the GI field to see whether this approach works for a much larger patient population, despite the low incidence.  Dr. Andrea Cercek: Dr. Chalabi just made a critical point that that is most important is to remember that we do have biomarkers in colorectal cancer that, in the neoadjuvant setting and in the metastatic setting, especially MSI, that we need to test for. And then, just to add from a clinical perspective, in rectal cancer, the large majority of patients that have mismatch-repair deficient or MSI tumors actually have Lynch syndrome. So really, if you identify a patient that's mismatch-repair deficient or MSI-high anywhere, but especially in the rectum, they absolutely should get germline testing. Dr. Mohamed Salem: I echo that and second that. And Dr. Cercek, thank you, and I know you did a lot of work in colorectal cancer in the younger adult population, too, so I think you've had a huge impact on that area too. I would like to thank both of you again for being here today, but more for the great work you and your teams are doing to advance the field. It's really a very exciting time in GI cancers now, and thank you so much for your work and for sharing your insights with us today on the ASCO Daily News Podcast.

Join Mahim, Samy, & Aman on exciting updates following the ASCO Gastrointestinal Cancers Symposium data readouts as we start 2023 with some exciting updates. In this episode, we share the latest news following recent approvals, 3-year data readouts, and developments in Gastrointestinal, Pancreatic, Colorectal, Hepatocellular Carcinoma, and Biliary Tract Cancer.

Both interviews in this episode are with presenters at the 2023 ASCO Gastrointestinal Cancers symposium. Dr. Myriam Chalabi (Netherlands Cancer Institute) discusses the TARZAN trial, which found that, in patients with rectal cancer, neoadjuvant radiotherapy followed by atezolizumab and bevacizumab resulted in an encouraging complete response rate. The findings of this phase 1 study demonstrate that total mesorectal excision may be prevented in a significant proportion of patients, increasing the chance for organ preservation and reducing the risk for long-term morbidity related to surgery. It is a small but very exciting study!But first, Dr. Laura Dawson (Princess Margaret Cancer Centre, Toronto, Canada) reviews her phase 3 study of single-dose radiotherapy to manage pain from hepatocellular carcinoma and liver metastases. The results of this trial delivered encouragingly good results, beyond even the palliative endpoint.  Enjoy listening!Additional reading:1.    Dawson LA, et al.

Gastrointestinal cancer experts Dr. Aparna Parikh and Dr. Kristin Ciombor discuss the treatment implications of the phase 3 PARADIGM trial and other advances in colorectal cancer with guest host and ASCO Daily News Associate Editor, Dr. Shaalan Beg.   TRANSCRIPT Dr. Shaalan Beg: Hello, and welcome to the ASCO Daily News Podcast. I'm Dr. Shaalan Beg, your guest host of the ASCO Daily News Podcast today. I'm an adjunct associate professor at UT Southwestern's Simmons Comprehensive Center and vice president of Oncology at Science 37. I'm delighted to welcome Dr. Aparna Parikh, and Dr. Kristen Ciombor to the podcast today. Dr. Parikh is an assistant professor of Medicine at Harvard University and a GI medical oncologist at the Mass General Hospital Cancer Center. Dr. Ciombor is an associate professor of Medicine and GI medical oncologist at the Vanderbilt University Medical Center. Today, we'll be discussing exciting new approaches using EGFR inhibitors as frontline therapy in colorectal cancer, and promising advances with immune therapy in the treatment of rectal cancer. Our full disclosures are available in the show notes, and disclosures of all guests on the podcast can be found in our transcripts at: asco.org/podcasts. Dr. Parikh, and Dr. Ciombor, it's great to have you on the podcast today. Dr. Aparna Parikh: Thanks so much. Dr. Kristen Ciombor: Thanks so much for having us. Dr. Shaalan Beg: We've seen some exciting advances in GI oncology this year. Let's start with colorectal cancer. Dr. Parikh, there have been many trials looking to compare EGFR and VEGF inhibitors in colorectal cancer. We've heard about the IDEA studies, the FIRE trials, and CALGB 80405. At the 2022 ASCO Annual Meeting, we heard the results of the PARADIGM trial. Have we finally answered the question of when to use EGFR inhibitors as frontline therapy for colorectal cancer? Dr. Aparna Parikh: Thanks so much, Dr. Beg, for this great question. It has been a really exciting year for colorectal cancer across the board. So, the anti-EGFR story is really interesting and has evolved. And maybe just for a little bit of background, we know that colorectal cancer originating from both the right and left side of the colon differ. So, they differ embryologically, and epidemiologically; there are different genetic and molecular aspects to right and left sides of colon cancers. And we have learned over time that in the era of targeted therapy, the primary tumor location has been found to play a very important role, not only in the prognosis of patients but to predict treatment response. We know that patients that have left-sided colon cancers-- and when we think about left-sided colon cancers, we think about cancers that originate from the splenic flexure and descending colon, sigmoid colon, rectosigmoid junction, and sometimes include the rectum in this as well. The rectals have slightly different molecular features than distal colons. And we know that these left-sided patients, overall, have better survival benefits than patients that have right-sided CRC. And that includes again, cecum, ascending colon, hepatic flexure, and transverse colon. So, we know that that had prognostic implications, but what about the predictive implications? And with ASCO, we saw some really exciting data with the PARADIGM study, as Dr. Beg highlighted. We have seen many examples in the past showing the predictive power of anti-EGFR therapy, and anti-EGFR therapy showing a detriment for patients on the right side of the colon. But all these results historically have been obtained by retrospective analysis. So, retrospective analysis of the pivotal CALGB 80405 study, which is the first-line biologic trial. FIRE-3, which is a similar study, but done out of Europe, and KRYSTAL. So all these studies show the same finding but were all obtained basically by retrospective analysis. And what we saw with PARADIGM this year, which is exciting to see, is that this was the first prospective trial to test the superiority of an anti-EGFR inhibitor panitumumab versus bevacizumab in combination with standard doublet first-line chemotherapy for patients that were RAS-wild type. I guess I forgot to mention that again, anti-EGFR therapies are only eligible for patients that are RAS-wild type. We know that RAS-mutant patients and RAS, KRAS HRAS patients don't respond to anti-EGFR therapy. So, the study was looking at RAS-wild type patients, and again, asking the question “was panitumumab better than bevacizumab in combination with chemotherapy for these RAS-wild type patients and for left-sided tumors?” It was a multicenter trial done in Japan-- and I always commend the Japanese on their work and their designs and ability to do these studies that ask really important questions. And, overall survival was the primary endpoint of the study in patients with left-sided tumors, but they also did a full set analysis including patients that didn't have left-sided tumors. They had 823 randomized patients. Many patients, a handful did not receive per-protocol treatment, and some were excluded for other reasons relating to inclusion criteria. And they had 400 patients that ultimately received panitumumab and 402 patients that received bevacizumab in the full set analysis. And of those patients, there were 312 and 292 respectively had left-sided tumors. And although the PFS was comparable between the treatment group, we saw that panitumumab in the left-sided patients actually did improve the OS in both patient populations. But when you looked at the left-sided tumors, the difference was 37.9 versus 34.3 months meeting statistical significance. So, this was an exciting study because it confirmed prospectively what we have seen time and time again, and really behooves us to do early biomarker testing and know RAS status early for these patients with right-sided tumors, as they do derive benefit from anti-EGFR. Maybe I'll just pause there and open it up for more questions or comments from Dr. Ciombor as well. Dr. Kristen Ciombor: Yeah, Dr. Parikh, I thought these data were encouraging. And as you mentioned, the first prospective data that we have in this setting now that we know this primary tumor sidedness matters. Just on a practical note, what do you do in practice? Do you give a lot of anti-EGFR in the first-line? I find that the toxicity can be challenging sometimes and patients may not want to do that. So, it leaves us in a quandary sometimes. Dr. Aparna Parikh: Yeah. So, what's interesting and I don't think we have this data clearly answered yet is, I had, especially for kind of a fit patient-- with the previous data that we've seen with TRIBE and others showing a survival benefit with triplet chemotherapy for first-line therapy, my inclination had actually been to prefer triplet-- and we know that triplet and anti-EGFR toxicity-wise is really, really tough to manage, and really no benefit there that we've seen with OS or PFS, even though you maybe do get a little bit of a better response rate with that. And so where I have sort of struggled is triplet versus just doing first-line doublet plus anti-EGFR. You know, we are not having a discussion about triplet today, but we also saw some data at ASCO showing that perhaps the benefit of the triplet, with the triplet study, is not as much as we had hoped it would've been too. So, it's a good question. I do tend to prefer triplet, I guess, overall, for the healthy, good performance status patient. And then, if not, then doublet. And we, unfortunately, don't have kind of rapid EGFR testing, we're pushing for that. In practice, I think having RAS/RAF status up front would be entirely helpful. It's lumped into our pan-tumor profiling, comprehensive genomic panels. We get microsatellite instability (MSI) status, which I know we'll talk about here next right away. But I think another reason that oftentimes we don't add it right away, is because we don't have the RAS status right away. So, you just start with a doublet and you may end up sneaking it on later. And then, I'd love to, maybe in another podcast, where we can discuss second-line anti-EGFR therapies and what people do in practice for those right-sided patients should they never get anti-EGFR and later-lines of therapy too. And I would argue, perhaps not, because we do see some patients that do benefit, but it can be challenging sometimes with a fresh new patient to make these decisions. But at least, feel encouraged that we're doing the right thing by adding anti-EGFR therapy if they can tolerate it for the left-sided RAS-wild type patient. How about you? What do you do? Dr. Kristen Ciombor: Yeah. Largely, it's a great question. And I don't love giving anti-EGFR therapy. We have an additional issue where I am geographically in that we don't ever give cetuximab because of the high rates of an infusion reaction. So, we pretty much stick to panitumumab and are glad to have that option. But I have started to talk to patients about toxicity and I'm really upfront with the survival data. And it's interesting how people choose differently in terms of what's important to them. And whereas a few extra months in the overall survival may be overshadowed by the toxicity that they have to go through to accomplish that. So, it's good to have many options though, and that's the important thing, and I think the takeaway, as well. Dr. Shaalan Beg: So, kind of brings it back to the fundamentals of practicing medicine, right? Bringing our patients and giving them the options that are most available to them. But I'm going to ask both of you one by one: So, if we have our patient with left-sided colorectal cancer, known as KRAS RAS-wild type, do you recommend EGFR therapy and VEGF therapy and allow the patients to decide, or do you feel that we decide if their profile is such that we should continue with VEGF therapy instead? Dr. Ciombor, do you want to go first? Dr. Kristen Ciombor: Yeah, I think both are good options. I don't only do bevacizumab in the first-line by any means because we do have that survival data. It mostly comes down to a discussion with the patient in terms of toxicities and survival and how well those balance out. Dr. Aparna Parikh: Yeah, very similar. I think we have also gotten a little bit more adept at managing toxicity. I'm pretty aggressive about prophylaxis with even doxy and topicals for managing the rash. And so, for some of my younger patients who are wanting to be "aggressive" and want the exposure to anti-EGFR early but are still very mindful of how it's impacting their day-to-day semblance of self, especially for the younger patients, try to be very proactive about side effect management. And then, of course, we have the patients that have the electrolyte wasting and things too that sometimes if it's bad, we are stuck with infusions frequently and you may end up dropping for those patients. But I think the rash at least I feel like for most patients we can manage if you're aggressive about it too. And I think we have gotten better at that than we were many years ago. Dr. Kristen Ciombor: Never thought we'd be dermatologists, did we? In training, that was definitely not a path I was good at. Dr. Shaalan Beg: Dermato-Oncology, rapidly growing field. So, Dr. Ciombor, the rectal cancer space has evolved very rapidly in recent years, especially when we hear about total neoadjuvant therapy, short-course radiation, watch-and-wait, for those with complete clinical responses. So at ASCO this year, we heard results on immune therapy and rectal cancer. Can you summarize where we are with immune therapy and rectal cancer? Dr. Kristen Ciombor: So, yes. We heard a lot this year at ASCO; both at ASCO GI and ASCO, from the Memorial group and Dr. Cercek's group. And this has been a really exciting advance that we're starting to see and potentially paradigm-shifting data. So, we know-- as you mentioned, that our treatment of rectal cancer, specifically, locally advanced rectal cancer has changed a lot in the last few years with a shift to more Total Neoadjuvant Therapy. And what the Memorial data showed was that for the patients who have microsatellite instability or mismatch repair deficiency, which admittedly, is a small group, but certainly ones that we see in clinic, those patients, on their trial were treated with six months of dostarlimab as neoadjuvant therapy prior to any other treatment; before radiation, surgery, et cetera, and no chemotherapy. And what they found was that actually, six months of dostarlimab in the first 14 evaluable patients actually induced a 100% clinical complete response rate. So, it's really unheard of in most of our trials to see 100%. And I think that caught everyone's attention for sure. I think we have to keep in mind who these patients were and are because they are currently being followed. So, for instance, these were patients that had pretty bulky node-positive disease, almost all these patients did. These were not really early-stage tumors. We did see that 100% were BRAF-wild type, so it does tell us maybe this is not completely the population that we're all seeing when we do see microsatellite instability since we see a lot of sporadic tumors with BRAF mutations. But on the whole, I mean, these were all MSI-high patients and treated with dostarlimab; the six months, that was the total amount of treatment that they received, though a few patients achieved that clinical complete response earlier at about three months, at the three-month reassessment. And what the clinical complete response rate was, was looking both radiographically, as well as endoscopically, and not seeing any sign of residual tumor. I think the important thing here is that median follow-up is still pretty short. There are a few patients who are approaching now two years past that dostarlimab therapy and have not had tumor recurrence, but overall, the median follow-up is still quite short. So, I think we do need to continue to follow these patients. We don't have overall survival data yet either. I think we still have a lot to learn, but this is a very encouraging start and certainly, something that could be really treatment-changing for these patients, which again, as Dr. Parikh was saying, we need this molecular profiling early to make treatment decisions right off the bat, not even only for metastatic now, but even for these locally-advanced rectal cancer patients. Because if you think about it, we've all taken care of patients who have to go through chemoradiation, and chemo, and surgery, and have a lot of morbidity from those treatments so that even if you cure them, they're left with a lot of toxicity. So, if we could avoid some of that, even potentially, surgery, that would be wonderful. But I do caution that this is not the standard of care yet. This is only based on 14 patients with short follow-ups at the current time. But the trial is ongoing, and there are other trials open in this space for patients who don't live in New York or can't get to New York. And for instance, ECOG-ACRIN study 2201 is treating these same patients with nivo and ipi, as opposed to dostarlimab. And that trial is open in about 80 sites now across the US. So hopefully, geographically near all of these patients. Dr. Shaalan Beg: I think a lot of us and a lot of our listeners, that Monday after the results were announced on ASCO had our phone lines and our patient secure messaging lines blowing up. Dr. Kristen Ciombor: We should have warned our nurses and our treatment teams that they would be fielding these questions, yes. On one hand, it's wonderful that our data and the science is getting out to patients. But I think we also have to be really careful as to what is reaching them because many of them didn't realize it was for this subset of patient populations. But great that they're asking those questions and wondering-- being advocates for themselves too. Dr. Shaalan Beg: You use the term clinical complete response. Can you talk about how we determine someone has a complete clinical response and what their follow-up looks like? Dr. Kristen Ciombor: Yeah. In the context of this study, it was actually, as I mentioned, it was both radiographic complete response, as well as endoscopic. So that's one thing that is a little bit tricky when you think about surveillance of these patients. So, it requires a lot, both in frequent surveillance, MRIs, FLEX SIGs often, digital rectal exams, sometimes doing PET scans or CTs, and patients who-- not only on this kind of study but also in non-operative management; watch-and-wait - really have to commit to very close, very frequent follow-up because if the cancer recurs, we don't want to miss that and lose our chance to cure them. So I think that's a little bit different everywhere, how that watch-and-wait approach really manifests, but I think we're learning how to do that, and working in a multidisciplinary group to make sure that patients get the surveillance that they need. Dr. Aparna Parikh: Yeah. I totally agree. If we offer, for the MSI-high patients, if we ultimately end up offering neoadjuvant immunotherapy-- and actually, I'm looking forward to your study, Dr. Ciombor, too, I think the monotherapy versus doublet, too, is going to come up for these patients. But I had a patient just a week or two ago that was starting on this approach with neoadjuvant immunotherapy, but for now, as a group, if we're proceeding down that and they do get a clinical complete response, we're deciding to forego even the radiation and surgery. We're following what they did in the OPRA study, which was pretty aggressive surveillance on the backend, both with direct visualization and MRIs, and you're seeing these patients every three months or so. Dr. Shaalan Beg: Well, thank you Dr. Ciombor and Dr. Parikh for sharing some valuable insights with us on the podcast today. Dr. Aparna Parikh: Thanks so much for having us. It was a lot of fun.

Daniel G. Haller, MD, of the University of Pennsylvania, Philadelphia, joins Blood & Cancer host David H. Henry, MD, also of the University of Pennsylvania, to review the top research presented at ASCO GI 2019. Plus, in Clinical Correlation, Ilana Yurkiewicz, MD, of Stanford (Calif.) University shares the story of a patient who had no questions about the details of his treatment but needed answers about the “big picture.”   Show Notes By Emily Bryer, DO, resident in the department of internal medicine, University of Pennsylvania, Philadelphia   Phase 2 trial of pembrolizumab (Keytruda), chemotherapy, and trastuzumab (Herceptin) in gastric cancer: Patients had previously untreated HER2 IHC+ or FISH+ tumors. Patients received pembrolizumab, trastuzumab/CAPOX (capecitabine and oxaliplatin) or FOLFOX (folinic acid, fluorouracil, and oxaliplatin). Patients all had a 100% response rate, prompting an ongoing phase 3 trial (KEYNOTE-811).   Third-line therapy for gastric cancer – TAGS, a phase 3 trial: supportive care vs. trifluridine plus tipiracil (Lonsurf): Gastrectomy did not affect outcome, safety, or pharmacokinetics. Neutropenia, a major toxicity, is manageable. Trifluridine and tipiracil are now a National Comprehensive Cancer Network Level 1 guideline for third-line therapy in patients with gastric cancer.   Neoadjuvant chemotherapy in pancreatic cancer: Compared neoadjuvant gemcitabine and S1 (NAC-GS) with upfront surgery for patients with pancreatic ductal adenocarcinoma and planned resection. Saw a significant survival benefit (37 months) of NAC-GS over upfront surgery (26 months).   Circulating tumor cells (CTC) in colorectal cancer: Studied patients with planned colonoscopies for colorectal screening. Took blood at the time of the procedure. Identified an absolute correlation with CTC and an increased disease burden in patients with colon cancer.   Additional reading:   Lancet Oncol. 2018 Nov;19(11):1437-48.  Oncotarget. 2018 May 11;9(36):24561-71.

Objectives: Bevacizumab is a monoclonal antibody that directly inhibits vascular endothelial growth factor, a key regulator of angiogenesis. Bevacizumab significantly improves progression-free and/or overall survival in metastatic colorectal cancer in combination with standard chemotherapy. This review describes the evolution of irinotecan-based regimens for metastatic colorectal cancer and evaluates the addition of bevacizumab to these regimens. Methods: Literature searches from large publication databases (PubMed, ASCO, ASCO GI, ESMO) were performed to capture key data relevant to bevacizumab, irinotecan, and the treatment of colorectal cancer. Results: Data from numerous large, multinational studies support the addition of bevacizumab to irinotecan-containing chemotherapy regimens for further improvement in patient outcomes. In a randomized, placebo-controlled trial, addition of bevacizumab to irinotecan significantly improved progression-free survival, overall survival and response rate in patients with metastatic colorectal cancer, and these results are supported by a number of other clinical trials and observational studies. Furthermore, the addition of bevacizumab to irinotecan improves outcomes regardless of K-ras mutational status. Bevacizumab has a well-established safety profile and the toxicities associated with its use are usually mild in severity and easily manageable. Conclusions: Addition of bevacizumab to irinotecan-containing regimens is an effective therapy option for the treatment of metastatic colorectal cancer. Copyright (C) 2010 S. Karger AG, Basel
