Richard Cathomas, MD, on MIBC: Perioperative Intravesical Recombinant BCG Combined With Chemoimmunotherapy
ASCO 2026
Richard Cathomas, MD, of Cantonal Hospital Graubünden, reviews results from the primary analysis of SAKK 06/19, an open-label single arm phase II trial, which found that the combination of intravesical recombinant bacillus Calmette-Guérin (BCG) with atezolizumab, cisplatin, and gemcitabine was feasible and safe without unexpected toxicities and demonstrates promising efficacy in patients with muscle-invasive bladder cancer (MIBC) (Abstract 4503).
Elizabeth Smyth, MD, of Oxford NIHR Biomedical Research Centre, Churchill Hospital, discusses three major studies presented at this year’s meeting: the antibody-drug conjugate izalontamab brengitecan in recurrent or metasatic esophageal squamous cell carcinoma (Abstract 4008); the ATTRACTION-6 study of chemoimmunotherapy in HER2-negative advanced gastric/gastroesophageal junction (GEJ) cancer (Abstract 4006); and an investigational EP4 antagonist in combination with chemoimmunotherapy as a first-line strategy for HER2-negative gastric/GEJ cancer (Abstract 4007).
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.
Gerneiva Parkinson, MD, of Stanford Cancer Institute, discusses time on treatment for systemic therapies among women with hormone receptor (HR)-positive breast cancer and a pathogenic variant in BRCA1, BRCA2, or PALB2 (Abstract 1096).

Christine Lovly, MD, PhD, FASCO, of City of Hope, offers her thoughs on the findings of the LIBRETTO-432 trial, which found improved event-free survival with adjuvant selpercatinib after definitive therapy for patients with early-stage RET fusion–positive non–small cell lung cancer (NSCLC) (Abstract LBA3).

Alicia K. Morgans, MD, FASCO, of Dana-Farber Cancer Institute, discusses data from the phase II ARACOG (AFT-47) randomized clinical trial, which compared the two androgen receptor pathway inhibitors’ effects on cognitive function in patients with advanced prostate cancer (Abstract 5005).
