Abstract

Twenty six patients with adenocarcinoma of the rectum were entered in a program of adjuvant "sandwich irradiation" at Pramongkutklao hospital. All patients were given a single dose of preoperative radiation 500 cGy one day before surgery. After surgical staging, the patients who had diseases beyond stage B1 (modified Astler-Coller staging) would receive postoperative radiation 4500-5400 cGy. Twenty one patients received full course of this treatment regimen, but only 16 patients could be followed up after completion of treatment. The mean follow up time was 35 months. The 2-year and 4-year Kaplan-Meier actuarial survival were 74% and 44% respectively. No severere treatment-related complication has been observed.
