The study evaluates the combination of immunotherapy of PD-1 antibody and neoadjuvant short-course radiotherapy in locally advanced rectal cancer (LARC). Patients are randomly assigned into two prospective cohorts: consolidation cohort and induction cohort. Consolidation cohort: A total of 65 patients will receive 55Gy short-course radiotherapy, followed by 6 cycles of capecitabine plus oxaliplatin (CAPOX) chemotherapy and PD-1 antibody, finally receive the total mesorectal excision (TME). Induction cohort: A total of 65 patients will firstly receive 2 cycles of CAPOX chemotherapy and PD-1 antibody, then receive 55Gy short-course radiotherapy, followed by 4 cycles of CAPOX chemotherapy and PD-1 antibody, finally receive the TME surgery. The rate of pathological complete response (pCR), long-term prognosis and adverse effects will be analyzed.
