Dr. Wang, thanks for coming on the podcast today.

Dr. David Wang: Well, thank you. It's a pleasure to be here.

Dr. Shaalan Beg: GI25 featured major therapeutic advances across the spectrum of GI malignancies, and it was exciting to hear about innovations and novel approaches that are shaping the future of our field. Before we start talking about specific abstracts, could you share some of your key highlights from the meeting?

Dr. David Wang: Sure. Our theme this year was “Breaking Boundaries to Enhance Patient Centered Care.” Past years’ themes have focused more on precision oncology, but we wanted to broaden our focus on patients and to be more holistic, which kind of led us into some of the Intersection [sessions] that we had. Each day started with a different Intersection. The first one was “Emerging Therapies in GI Cancers”, where invited speakers talked about bispecific antibody drug conjugates, theranostics, CAR T and other cell-based therapies. The second day was on “Personalized Risk Assessment for GI Cancers,” and this included looking at polygenic risk scores for colorectal cancer, microRNAs and liquid biopsies such as exosomes and pancreatic cancer and non-endoscopic screening modalities in esophageal cancer. And on our final day, we wanted to talk about “
