Dr. Rachna Shroff, chair-elect of the 2023 ASCO GI Cancers Symposium, and guest host Dr. Shaalan Beg discuss new research presented at GI23, including new data from SWOG 1815 in biliary tract cancers, advances in biomarker studies in mCRC such as the PARADIGM trial, and promising updates in ctDNA technology. She also highlights the exciting potential of AI in oncology. 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 highlights from the 2023 ASCO Gastrointestinal Cancer Symposium, which celebrated 20 years of transformative care in GI cancers. I'm delighted to welcome Dr. Rachna Shroff, the chair-elect of this milestone meeting. Dr. Shroff is the interim division chief of Hematology Oncology at the University of Arizona Cancer Center. She also serves as the associate dean for Clinical and Translational Research and is the chief of GI Medical Oncology. Our full disclosures are available in the transcript of this episode, and disclosures related to all episodes of the podcast are available on our transcripts at ASCO.org/podcasts. Dr. Shroff, it's great to have you back on the ASCO Daily News podcast. Dr. Rachna Shroff: Thank you so much for having me. I'm so excited to be here. Dr. Shaalan Beg: The ASCO GI Cancers Symposium has been heralded as one of the biggest conferences in the GI cancer space and has occupied this space for the past two decades. Some would say that this year's conference was probably the best GI Cancers Symposium to date. Can you comment on the 20th anniversary milestone and the impact of the symposium on GI cancers? Dr. Rachna Shroff: Absolutely, and that's so great to hear that that's the feedback that you've heard. I have to say GI ASCO is absolutely my favorite meeting of the year, so that is my full disclosure. But I think that this was a tremendous meeting, and I think it was so beautiful that it was also coinciding with the 20th anniversary. It meant so much to us to have Dr. Margaret Tempero open the meeting because she really was the impetus for creating a GI cancer-focused meeting that really brought together multidisciplinary expertise. And so to us, that is what this 20th anniversary represented—20 years of multiple different specialties coming together to discuss how to improve cancer care for patients with gastrointestinal malignancies. And it has been a transformative meeting to see the impact of research presented at this meeting and how it has been implemented over the course of 20 years. And I completely agree that this year in and of itself had some incredible pivotal data that there is no doubt will be practice-changing, and that is absolutely the purpose. I also think that the beauty of this meeting is the networking opportunities for all of us to come out of our individual silos, come together, and discuss cross-cutting care across the spectrum of GI malignancies. And I think that this meeting really did that quite well. Dr. Shaalan Beg: There were many practice-changing studies that made headlines this year, and for me, one of the most anticipated studies was a trial that you led for cholangiocarcinoma and much-anticipated results. The study finished enrollment at a record pace. Can you share your key findings of cholangiocarcinoma? And I'd really like to hear your perspective on cholangiocarcinoma studies. Dr. Rachna Shroff: Yes, it was actually a really big year in the hepatobiliary space, and I was proud to present SWOG 1815, LBA 490, which was the pivotal randomized phase 3 trial looking at gemcitabine, cisplatin, and nab-paclitaxel versus gemcitabine and cisplatin. This was a study that was opened across the entire NCTN and based on a single-arm phase 2 trial that had shown some promising early efficacy of
