The goal of this clinical trial is to evaluating the efficacy and safety of radiotherapy combined with Tislelizumab, Liposomal Irinotecan, and Capecitabine in patients with locally advanced mid-lower rectal cancer with pMMR.. Patients would be included as:1. Aged between 18-75 years, with no gender restrictions; 2. Biopsy pathology confirmed as pMMR type locally advanced mid-lower rectal adenocarcinoma (tumor lower margin ≤ 10 cm from the anal verge); 3.With the following high-risk factors: T3N+/T4/N2/EMVI+/MRF+/lateral lymph node metastasis/inability to preserve anal function during surgery; 4.
