Role of Gut Microbiota in Neoadjuvant Radioimmunotherapy for MSS, Locally Advanced Rectal Cancer
NCT06898359 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 29
Last updated 2025-03-27
Summary
This research investigates the role of the gut microbe in patients receiving radioimmunotherapy with locally advanced microsatellite-stable (MSS) rectal cancer. Given the limitations of current treatment strategies in achieving optimal clinical outcomes, this prospective, single-center, phase II clinical trial aims to improve pathological complete response (pCR) rates. The primary endpoint is pCR, with secondary endpoints including disease-free survival (DFS) and the incidence of treatment-related adverse events. This study seeks to provide insights into a novel treatment paradigm for MSS locally advanced rectal cancer, potentially offering improved therapeutic options for this patient population.
