[Analysis of 5-year survivors of esophageal cancer treated with radiation and chemotherapy].

From 1967 to 1980, 240 cases of esophageal cancer, consisting of 153 curative and 87 palliative cases, were treated with a combination of radiation and chemotherapy. The five-year survival rate in 124 curative cases given a dose of more than 50 Gy was 12.9%, and 17 cases survived more than 5 years. In the 5-year survivors, T1 in the advancement of tumors, less than 7 cm in length, and cancer of both the serrated and tumorous types were characteristic factors, indicating a good prognosis. These cases were irradiated with a dose of 60-70 Gy and the tumors showed a high response to irradiation.
