What this Trial Is About

This study is a multicenter, single arm, prospective study aimed at evaluating the efficacy and safety of adebelimab combined with short course radiotherapy (5 \* 5Gy) and chemotherapy as preoperative neoadjuvant therapy for locally advanced rectal cancer patients. In the study, all subjects who met the inclusion criteria will receive a combination of adebelimab, short course radiotherapy (5 \* 5Gy), and CAPOX chemotherapy as neoadjuvant therapy according to the study plan. TME surgery will be performed 2-3 weeks after the last dose of neoadjuvant therapy. If the surgery cannot be performed within the time window specified in the protocol (such as delayed adverse reactions, etc.), the researcher will consider the actual clinical situation of the subjects comprehensively.
