Active Comparator
Short-course radiotherapy sequential Tislelizumab combined with CapeOX (group A)
Short-course radiotherapy sequential CapeOX (group B)
Standard SCRT: A total radiation dose of 25 Gy was delivered in 5 fractions (from day 1 to 5) Sequential treatment period: After resting for 3-7 days following completion of SCRT, patients were treated with 4 cycles of CapeOX (Oxaliplatin 130 mg/m2 intravenously, day 1; Capecitabine 1000 mg/m2, Bid,days 1-14) and an additional intravenous infusion of 200mg Tislelizumab on the first day of each cycle of CapeOX. Surgery: After 3 weeks of the completion of neoadjuvant therapy, the TME surgery was performed. Postoperative adjuvant chemotherapy: Whether postoperative chemotherapy was implemented mainly depended on the patient's wishes, and 2 cycles of CapeOX with or without Tislelizumab will be undergone to these willing cases.
