Due to the universal application of endoscopy, Japan has found that superficial esophageal cancer has increased. From 1979 to 1982, it accounted for 8.5% of esophageal cancers treated, compared with 16% in 1986. Therefore, patients with radiotherapy also increased. This article assessed the results of radical radiotherapy for 105 cases of superficial esophageal cancer in 15 hospitals from 1981 to 1990. Superficial cancer refers to the area where the tumor is limited to the epithelium to the submucosa. Male 89 cases, female 16 cases, aged 50 to 88 years, mean 70 years old, histology are squamous cell carcinoma. Tumor length 1 ~ 10cm, an average of 2.8cm. Two patients had recurrence after laser treatment and three patients received chemotherapy before radiotherapy. Depth of tumor invasion with endoscope
