From 198 8 - 0 6 to 1 994- 0 6 , 316 patients with esophageal cancer were treated in radiotherapy department, of which 222 were males and 104 were females. All patients were irradiated with 60 Co, and the tumor volume was 60-70 Gy/6-8 weeks. The patients were followed up for more than 5 years. The follow-up rate was 91.1%. The one-, three-, and five-year survival rates were 536%, 237%, and 134%, respectively. The effect of radiotherapy is closely related to the age of the patient, the location of the lesion, the length of the lesion, the degree of obstruction, the metastasis, the degree of improvement of the lesion after radiotherapy, and the radiotherapy absorption. The main reasons for the failure of radiotherapy are uncontrolled local tumors and tumor recurrence and metastasis
