Muscle-invasive bladder cancer (MIBC)

Authored by Open Medicine, published on 2026-04-09 23:26:03.0

This algorithm outlines a contemporary management approach for muscle-invasive bladder cancer, stratifying patients by cisplatin eligibility and surgical candidacy to guide the use of neoadjuvant chemotherapy, perioperative immunotherapy, or bladder-preserving chemoradiation. It incorporates emerging phase III data supporting perioperative checkpoint inhibitors and antibody–drug conjugates, along with established adjuvant immunotherapy for high-risk residual disease after cystectomy.
