[MUSIC PLAYING]   BRITTANY HARVEY: Hello and welcome to the ASCO Guidelines Podcast Series brought to you by the ASCO Podcast Network, a collection of nine programs covering a range of educational and scientific content and offering enriching insight into the world of cancer care. You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey. And today, we're continuing our series on the management of immune-related adverse events. I am joined by Dr. Yinghong Wang from the University of Texas MD Anderson Cancer Center in Houston, Texas, author on Management of Immune-Related Adverse Events in Patients Treated With Immune Checkpoint Inhibitor Therapy: ASCO Guideline Update and Management of Immune-Related Adverse Events in Patients Treated with Chimeric Antigen Receptor T-Cell Therapy: ASCO Guideline. And today, we're focusing on gastrointestinal toxicities in patients treated with immune checkpoint inhibitor therapy. Thank you for being here, Dr. Wang. YINGHONG WANG: Thank you, Brittany. It's my great pleasure to be invited to participate in this education event. I'm happy to share my experience and the knowledge that I learned over all the research studies in this field and share with the readers or the community providers on this specific topic. BRITTANY HARVEY: Great. Thank you. Then, first, before we get into the content, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The full conflict of interest information for this guideline panel is available online with the publication of the guidelines in the Journal of Clinical Oncology. Dr. Wang, do you have any relevant disclosures that are directly related to these guidelines? YINGHONG WANG: I do have consulting services to two pharmaceuticals, but they're not related to the current guidelines that are published from the ASCO. They're Tillotts Pharma and Athenex Pharma. BRITTANY HARVEY: OK. Thank you. Then, let's talk about these gastrointestinal toxicities. So first, what are the immune-related gastrointestinal toxicities addressed in this guideline? YINGHONG WANG: So these particular guidelines have provided very detailed description on the incidence and clinical presentations and also recommendations on the evaluation and treatment for the upper and the lower gastrointestinal adverse events and the liver and even other organ toxicity, including the exocrine pancreas toxicities that are being categorized as GI field related to checkpoint inhibitor treatments. BRITTANY HARVEY: OK. And then what are the key recommendations for the identification, evaluation, and management of colitis? YINGHONG WANG: So colitis is definitely one of the most common organ to be involved in this category of toxicity-related checkpoint inhibitors. And that's why a lot more studies have been studied because the patient volume can allow enough power to run a lot of analysis. I think the summary that I would say-- the recommendations from the current ASCO Guidelines inc
