Welcome back to the Oncology Brothers podcast! In this episode, we continue the CME series on HER2-positive GEJ and gastric cancer, shifting focus to the essential topic of treatment toxicity management. We're joined by two leading experts: Dr. Geoffrey Ku from Memorial Sloan Kettering and Dr. Shruti Patel from Stanford University.

Building on their previous discussion of upper GI treatment algorithm with Dr. Rutika Mehta, this episode delves into the practical realities of managing patients on complex regimens. Drs. Ku & Patel break down the side effect profiles across the treatment continuum—from frontline trastuzumab-based combinations to emerging therapies like zanidatamab—and provide actionable strategies for community oncologists.

Episode Highlights: • Practical management of frontline side effects with FOLFOX/XELOX chemotherapy plus trastuzumab and pembrolizumab • Reality check on trastuzumab cardiotoxicity: incidence rates and monitoring protocols in gastric vs. breast cancer • Immune-related adverse events with checkpoint inhibitors: what's common vs. rare in GI cancers • Critical insights on zanidatamab's synergistic diarrhea toxicity and mandatory prophylaxis strategies • TDXd (Enhertu) in second-line: moving beyond ILD fears to address frequent cytopenias and marrow management • Expert consensus on infusion reaction management for novel biologics • The importance of managing baseline symptoms in patients with dysphagia and nausea

This episode bridges the gap between trial data and clinical practice, offering real-world wisdom on keeping patients on effective therapies through proactive toxicity management.
