  • Mid-low rectal cancer, with the lower edge of the tumor located within 12 cm from the anal verge;
  • Magnetic resonance imaging (MRI) suggests locally advanced rectal cancer (T3 or T4 and M0), accompanied by at least one of the following risk factors: cT4, N2, lymphovascular invasion, involvement of the mesorectal fascia, or enlarged lateral lymph nodes (short-axis diameter \> 8 mm); patients with potentially resectable disease;
  • Polymerase chain reaction (PCR) testing indicates microsatellite stability (MSS) type;
  • No prior antitumor therapy, such as chemotherapy, radiotherapy, immunotherapy, or targeted therapy;
  • Age between 18 and 75 years;
  • ECOG Performance Status (PS) score of 0-1;
  • Laboratory test results: WBC ≥ 3.5 × 10\^9/L, Hb ≥ 100 g/L, PLT ≥ 100 × 10\^9/L; normal liver and kidney function;
  • Absence of severe comorbidities, and ability to tolerate surgical treatment;
  • The patient or their immediate family member voluntarily agrees to participate in this study and provides written informed consent.

You may not qualify if:
