Symptomatic recurrences of carcinoma of the rectum and sigmoid. The influence of radiotherapy on the quality of life.
One hundred forty-three patients irradiated for locoregional recurrences after curative surgery for cancer of the rectum and sigmoid were studied retrospectively. An analysis was made of the symptomatic response and survival in the total series and in three subgroups treated with different dose levels (40 Gy or lower, between 40 and 50 Gy, 50 Gy or higher). The symptom-free period was calculated as percent of the overall survival. Symptomatic control was obtained in 80.4 percent of the cases, and the crude patient survival rate was 17.5 percent at two years. No significant difference was found in the three subgroups treated with different dose levels. The cumulative time/patient asymptomatic periods in the total series and in the three subgroups were 31.5, 30.2, 31.8, and 31.9 percent respectively, of the survival period.
