Summary

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.

Detailed description

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)

Conditions

• Rectal Cancer
