G.I. E25: Rectal Organ Preservation: Watch-and-Wait and dMMR Immunotherapy.

Episode 25: Rectal Organ Preservation: Watch-and-Wait and dMMR Immunotherapy. Rectal organ preservation depends on more than a reassuring scan. In this episode, we examine clinical response assessment, watch-and-wait surveillance, regrowth and salvage, and the OPRA sequence, then consider the separate dMMR immunotherapy pathway with attention to biomarker confirmation, follow-up, and the maturity of the evidence.
