Short-course Radiotherapy Based TNT Combined With PD-1 Inhibitor for Locally Advanced Rectal Cancer

Summary

TORCH is a prospective, multicentre, randomized phase II trial. 130 LARC (T3-4/N+M0, distance from anal verge ≤12cm) patients will be treated with total neoadjuvant therapy (TNT) and assigned to Group A and Group B. Group A receives SCRT (25Gy/5Fx) followed by 6 cycles of Toripalimab combined with CAPOX (ToriCAPOX). Group B receives 2 cycles of ToriCAPOX followed by SCRT and 4 cycles of ToriCAPOX. TME surgery is scheduled after TNT while a watch and wait (W\&W) option can be applied to patients achieving clinical complete response (cCR). The primary endpoint is complete response (CR, pathological complete response \[pCR\] plus cCR) rate. The secondary endpoints include the grade 3-4 acute adverse effects (AE) rate, 3-year DFS rate, etc.
