Pre-operative radiotherapy as adjuvant treatment in rectal cancer.
From January, 1975 to December, 1987, 241 patients with rectal cancer underwent pre-operative irradiation and surgical resection. The radiation was delivered with 25 MeV photons, 5 days per week by 2.4 grays fractions up to a total dose of 36 grays. Surgery was curative in 195 patients; 57% had abdomino-perineal resection. Irradiation had to be discontinued in 3 patients and 4 patients subsequently developed severe acute ileitis. Postoperative mortality rate was 2.9%. The most frequent postoperative complications were delayed healing of abdominal wounds (18%) and perineal wounds (14%). Severe late complications occurred in 27 (13%) patients. The incidence of intestinal obstruction was 5%. Follow-up survivors ranged from 18 months to 13 years. Local failure occurred in 24 (12%) of the 195 patients. Local failure rates were 10% for Dukes' A tumors, 11.6% for Dukes' B, and 22.7% for Dukes' C tumors. Five and 10 year actuarial survival rates after curative surgery were 70% and 52%. The Dukes' classification was the only factor that influenced survival.
