Objective: To explore the palliative treatment effect of radiation therapy on locally advanced or postoperative recurring rectal cancer and its influence on the quality of life of patients. METHODS: Twenty-nine patients with locally advanced or recurrent rectal cancer were treated with 60 Co pelvic anteroposterior irradiation or two anterior posterior fields, DT 4 0-60 Gy. Results: The remission rate of all symptoms after radiotherapy was 100%. The complete remission rate of pain was 44.8%, the analgesic efficiency was 100%, and the median control time was 5 months. After the end of radiotherapy for all patients, the average Karnofsky score of 68 months was 9 months, and the average score before radiotherapy was 479. With a median survival time of 11 months, 8 patients had good pelvic symptoms at the time of death. Conclusion : Radiotherapy plays a role in alleviating symptoms, controlling pain, and improving quality of life in palliative treatment of rectal cancer patients with locally advanced pelvic or recurrence
