Results of radiotherapy for inoperable locally advanced esophageal cancer
Abstract
Three hundred and eleven patients with locally advanced esophageal cancer were treated by radiation therapy from 1968 to 1983 at Tokyo Women's Medical College. Of these, 288 patients with previously untreated, histologically confirmed squamous cell carcinoma but previously treated with curative intent, were eligible for analysis. The cumulative 5-year survival rate of 288 patients given radical radiotherapy was 9.0%. Sex, tumor length, and Stage (AJC) had a great influence on prognosis. The five-year survival rate in males was 5.4% and in females was 22.4%. The five-year survival rate in cases with a tumor length of 5 cm or less was 17.7% in 5-10 cm was 10.0%, and in 10 cm or above was 2.8% and they were 20.2% for Stage I, 9.9% for Stage II, and 2.6% for Stage III. There were no significant differences of survival rate among age, tumor site, and tumor type on X ray film. This data suggests that comparatively early, small-volume tumors share a significant potential for cure by radiotherapy, but potent combined therapy is necessary for the treatment of advanced cancers.
