Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Evaluation indexes: (1) the primary evaluation index: disease-free survival (disease free survival, DFS); (2) the secondary evaluation indexes: pathological complete remission rate (pCR), the 3 year overall survival (overall survival, OS); R0 dissection rate; distant metastasis free survival (DMFS); local recurrence free survival rate (LRRFS); tumor regression grade (TRG, tumor regression grade) and the adverse reaction rate during the chemotherapy, the operation safety index; quality of life; psychological and cognitive effects, assessment of nutritional status.
Safety evaluation indexes: including all adverse events observed during the experiment.
Number of patients: 458 cases Study design: patients will be randomly assigned into the total neoadjuvant treatment group (experimental group, TNT) and neoadjuvant concurrent chemotherapy group (control group, CRT) in the ratio of 1: 1. The patients of experimental group will be given 1 cycle of induction CAPOX (Oxaliplatin 130mg/m2 d1, Capecitabine 1000mg/m2, bid, d1-14) prior to radiotherapy. Then pelvic IMRT/VMAT (50-50.4Gy/25-28f) and two cycles of concurrent chemotherapy (Oxaliplatin 130mg/m2, d1, d 22, Capecitabine 825mg/m2, bid, 5d/w, 25-28d) are performed. And three cycles of consolidation chemotherapy (CAPOX) are delivered after concurrent chemoradiotherapy. Total mesorectal excision (TME) is performed after completion of the whole neoadjuvant treatment. The patients of control group will receive standard concurrent neoadjuvant chemoradiotherapy with capecitabine (825mg/m2, bid, 5d/w) followed by TME 6-8 weeks after the end of concurrent chemoradiotherapy. Then, patients are treated with another 6 cycles of CAPOX.
Schedule: Investigators plan to finish the study in 4 years and write the related work within 2 years after the completion of this study.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Total neoadjuvant treatment
The interventions of experimental group include 1 cycle of CAPOX before radiotherapy; and then start concurrent chemoradiotherapy with CAPOX regimen (capecitabine: 825mg/m2, bid, 5d/w; oxaliplatin, 130mg/m2, D1, q3w) for 2 cycles followed by 3 cycles of CAPOX 2-3 weeks after the completion of radiotherapy. Intensity modulated radiotherapy (IMRT/VMAT) was used for radiotherapy, and the dose was 50-50.4Gy/25-28f, 1.8-2.0Gy/d, 5f/w. The TME operation will be given 3-4 weeks after the end of the total neoadjuvant treatment.

TME
The TME operation will be given after the end of the neoadjuvant treatment.
concurrent chemoradiotherapy group
The interventions of control group is standard preoperative concurrent chemoradiotherapy. The radiotherapy target areas and dosage are the same as group TNT. During radiotherapy, only oral capecitabine will be delivered and capecitabine dose was 825mg/m2, bid, 5d/w. The TME surgery will be performed 6-8 weeks after the end of concurrent chemoradiotherapy. Then, patients will receive another 6 cycles of CAPOX.
