An interview with Dr. Milan Anadkat from Washington University & Dr. Aung Naing from MD Anderson Cancer Center, authors on “Management of Immune-Related Adverse Events in Patients Treated With Immune Checkpoint Inhibitor Therapy: ASCO Guideline Update.” They discuss recommendations for cutaneous toxicities in patients receiving ICPis, including rash, bullous dermatoses & SCAR in Part 3 of this 13-part series.

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. Milan Anadkat from Washington University in St. Louis, Missouri. And Dr. Aung Naing from the University of Texas M.D. Anderson Cancer Center in Houston, Texas, authors 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 cutaneous toxicities in patients treated with immune checkpoint inhibitor therapy. Thank you for being here Dr. Anadkat and Dr. Naing. AUNG NAING: Thank you for having us. MILAN ANADKAT: Thank you. BRITTANY HARVEY: 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. Anadkat, do you have any relevant disclosures that are directly related to these guidelines? MILAN ANADKAT: As listed in the document, I don't have any direct disclosures. I do have a number of indirect disclosures, as I've consulted on similar topics in the past. BRITTANY HARVEY: Thank you. Then Dr. Naing, do you have any relevant disclosures that are related to these guidelines? AUNG NAING: I do not have. BRITTANY HARVEY: Great, then let's get into the content of this guideline and the cutaneous toxicities that we're here today to talk about. So Dr. Naing, what are the immune-related cutaneous toxicities addressed in this guideline? AUNG NAING: Well, with the advancement of immunotherapy, we've seen better response in our cancer patients. However, together with such positive outcomes, we are also seeing side effects caused by the immunotherapy. Disruption of the homeostatic mechanisms include a unique spectrum of side effects or immune related adverse events, commonly called IRAEs. The most common immune related adverse events in patients receiving checkpoint inhibitors are dermatitis, enterocolitis, transmitis, and endocrinopathies. However, if you look at the most commonly reported IRAE of any grade, it is dermatologic toxicity. So here in this guideline, we addressed how to take care of the patients when they are having these side effects, particularly with the cutaneous toxicities. So when you look at that time to median onset of skin toxicities, it ranges from two to five weeks. And using CTCAE criteria for grading is a challenge for skin toxicity, as it may not reflect
