At ASCO GU 2026, the group discussed results from KEYNOTE-B15, a phase III trial evaluating perioperative enfortumab vedotin plus pembrolizumab versus standard gemcitabine-cisplatin in muscle-invasive bladder cancer. The EV-pembrolizumab regimen significantly improved event-free survival, overall survival, and pathologic complete response rates, highlighting its potential to redefine perioperative treatment. They also emphasized the importance and limitations of pathologic complete response as a surrogate endpoint, particularly as the field continues to explore bladder preservation strategies.
