ASCO 2026
Sara A. Hurvitz, MD, FACP, of Fred Hutchinson Cancer Center, provides an update focusing on progression-free survival after next line of treatment and subsequent therapies among patients enrolled in the ASCENT-03 trial.

Samuel J. Klempner, MD, FASCO, of Mass General Brigham Cancer Institute, discusses a single-arm phase II study—which is currently open and enrolling (ClinicalTrials.gov identifier NCT07070466)—evaluating ivonescimab in combination with FOLFOX as front-line therapy in locally advanced, unresectable, or metastatic HER2-negative gastroesophageal adenocarcinoma (Abstract TPS4246).
Laura Alder, MD, of Duke University Medical Center, highlights emerging data discussed in the meeting’s oral abstract session on small cell lung cancer, including increased toxicity without efficacy benefit from concurrent chemoradiation and immunotherapy, the intracranial activity of tarlatamab-dlle, and early data for a SEZ6-targeting antibody-drug conjugate.
Walter Weber, MD, of University Hospital Basel, presents data from the international randomized phase III PREPEC trial (OPBC-02), which found prepectoral implant-based breast reconstruction (IBBR) significantly and relevantly improved long-term quality of life—at the cost of a higher risk of loss or replacement of expander or implant—compared to subpectoral IBBR (Abstract 504).
