Primary Outcome Measures :
  1. Pathological response rate [ Time Frame: two weeks after surgery ]
    Tumor Regression Grade 0-1


Secondary Outcome Measures :
  1. Pathological complete response rate [ Time Frame: two weeks after surgery ]
    Refers to the pathological examination of primary tumors and lymph node surgical specimens without residual infiltrating tumor cells (ypT0N0, TRG 0)

  2. 2-year local control rate [ Time Frame: 2 years after enrollment ]
    Refers to the probability of not finding local recurrence of tumor within 2 years，including anastomotic recurrence confirmed by pathological biopsy, pelvic tumor recurrence confirmed by imaging examination, or suspected pelvic recurrence with CEA exceeding the normal upper limit.

  3. 2-year metastasis-free rate 2-year distant metastasis free rate [ Time Frame: 2 years after enrollment ]
    Refers to the probability of no distant metastasis within 2 years

  4. Overall survival [ Time Frame: 2 years after enrollment ]
    Refers to the time from the start of treatment to death due to any cause.

  5. disease-free survival [ Time Frame: 2 years after enrollment ]
    Refers to the time from the start of treatment to recurrence.
