Patients with locally advanced rectal cancer (T3-4/N+) were randomly assigned to experimental group A or control group B according to the ratio of 1:1,who will receive preoperative neoadjuvant therapy, and the Primary endpoint of the study is Pathological complete response rate(PCR ) assessed by the blind independent review committee (BIRC), defined as the absence of viable tumour cells in the resected primary tumour specimen and all sampled regional lymph nodes (ypT0N0)
The study is a multicenter, open-label, randomized controlled clinical study, and the purpose of the study is to compare the pathological complete response rate (PCR) of patients with locally advanced rectal cancer treated with short-term radiotherapy, sequential Camrelizumab and CAPOX (group A) to long-term concurrent chemoradiotherapy, sequential CAPOX (group B) in patients with LARC. A total of 230 patients were included in this study.
