The Combination of Immunotherapy and Neoadjuvant Chemoradiotherapy in MSS Locally Advanced Rectal Cancer

June 1, 2020 updated by: Zhen Zhang, Fudan University

A Phase II Trial of Immunotherapy Combined With Neoadjuvant Chemoradiotherapy in Microsatellite Stable Locally Advanced Rectal Cancer

The study evaluates the addition of immunotherapy of PD-1 antibody in neoadjuvant chemoradiotherapy in microsatellite stable (MSS) locally advanced rectal cancer (LARC). A total of 50 MSS LARC patients will receive 2 cycles of PD-1 antibody, followed by capecitabine plus irinotecan radiosensitized neoadjuvant chemoradiotherapy, and another 3 cycles of PD-1 antibody, finally received the total mesorectal excision (TME) and 6 cycles of adjuvant chemotherapy of XELOX. The tumor response grade, adverse effects and long-term prognosis will be analyzed.
