Welcome to the Oncology Brothers podcast! In this episode, we were joined by Dr. Rutika Mehta, a GI medical oncologist from Weill Cornell. Together, we dived into the current treatment landscape for advanced metastatic gastroesophageal junction (GEJ) and gastrointestinal carcinoma, with a special focus on HER2-positive disease. Episode Highlights: • Overview of recent advancements in the treatment of resectable disease, including the approval of Durvalumab in perioperative settings. • Discussion on the importance of biomarker testing, including HER2, PD-L1, MMR, and Claudin 18.2, in determining treatment options. • Insights into frontline treatment strategies for HER2-positive patients, including the role of trastuzumab and the addition of pembrolizumab based on PD-L1 status. • The significance of retesting HER2 expression upon disease progression and the implications for treatment decisions. • Exploration of emerging therapies like TDXd and Zanidatamab, and their potential impact on the treatment landscape. • Considerations for managing side effects and the importance of treatment sequencing in palliative care. Join us for an informative discussion that aims to keep community oncologists up to date in this ever-evolving field of cancer treatment.
