Locally advanced disease assessed by pelvic MRI, classified as cT3-4aN0M0 or any T stage with node-positive (N+) disease, without distant metastasis (M0), according to the AJCC 8th edition staging system.\n5. The lower edge of the tumor is located within 10 cm from the anal verge (defined as low\u002Fmid rectal cancer).\n6. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.\n7.

Evidence of distant metastasis (M1 disease) on baseline imaging.\n2. Previous radiotherapy to the pelvis, or any prior systemic chemotherapy, targeted therapy, or immunotherapy for colorectal cancer.\n3. History of other active malignancies within the past 5 years, except for adequately treated carcinoma in situ of the cervix, basal cell carcinoma of the skin, or other localized tumors considered cured by local treatment.\n4. Any of the following uncontrolled conditions or comorbidities:\n\n1）Severe active infection requiring systemic therapy. 2）Unstable angina, myocardial infarction, or congestive heart failure (NYHA Class II-IV) within the last 6 months.\n\n3）Uncontrolled epilepsy, central nervous system disorders, or psychiatric disorders that would compromise the ability to provide informed consent or comply with study procedures.\n\n5\\. Known history of severe immunodeficiency or active autoimmune disease requiring systemic immunosuppressive therapy (e.g., corticosteroids at doses \\> 10mg\u002Fday prednisone equivalent) within the past 2 years.\n\n6\\. Known history of hypersensitivity to any component of the study drugs (Liposomal Irinotecan, Capecitabine, Camrelizumab) or history of severe hypersensitivity reactions to other monoclonal antibodies.\n\n7\\. Pregnant or lactating women, or subjects of childbearing potential who are unwilling to use highly effective contraception during the study period and for at least 6 months after the last dose of study treatment.\n\n8\\.

The purpose is to see if a new combination of treatments given before surgery (neoadjuvant therapy) can more effectively shrink the tumor and increase the chance of curing the cancer or avoiding surgical removal of the rectum.\n\nThe main things you will do in this study are:\n\n1. Receive a Short Course of Radiation Therapy (5 treatments over 1 week).\n2. After a 1-week break, receive a combination of three drugs:\n\n1）Nal-IRI (a special form of the chemotherapy drug Irinotecan, designed to have fewer side effects) 2）Capecitabine (a chemotherapy pill) 3）Camrelizumab (an immunotherapy drug) 3. This drug combination is given in 8 cycles, with each cycle lasting 3 weeks. 4. After finishing all cycles, the doctors will carefully check how the tumor responded.\n\nThe most important goal of this research is to see how many patients achieve a \"Complete Response,\" which means:\n\n1. No sign of cancer cells in the surgically removed tissue (Pathological Complete Response, pCR), or\n2. No sign of cancer can be found through clinical exams, scans, and scopes, allowing the patient to avoid immediate surgery under a \"Watch and Wait\" strategy (Clinical Complete Response, cCR).\n\nResearchers will also monitor:\n\n1. The safety of the treatment and its side effects.\n2. How well the cancer is controlled over time (e.g., 3-year survival without cancer recurrence).\n3. The rate of successful tumor removal and the rate of preserving the anus.",[80],"Rectal Cancer Patients",[82,83,84,85,86],"Locally advanced rectal cancer","pMMR\u002FMSS","Short-course radiotherapy","Liposomal irinotecan","Neoadjuvant immunochemoradiotherapy","NOT_YET_RECRUITING","2026-04-08",{"date":90,"type":91},"2026-04-13","ACTUAL",{"date":93,"type":74},"2026-05-20",{"date":95,"type":74},"2034-12-31",{"name":5,"class":6},1]
