1990年11月～1991年7月治疗100例食管癌病人,随机分为两组即超分割组和常规分割组。每组50例,每天照射量和总量两组相似。总肿瘤量65Gy～70Gy/34～36天。超分割组每天照射2次,间隔6～8小时。结果超分割组病灶消失,饮食改善及胸痛缓解的时间均优于常规组。且放疗反应轻,生存质量好。局部复发及锁上转移率两组相似。我们认为超分割放疗食管癌是可取的。
From November 1990 to July 1991, 100 patients with esophageal cancer were randomly divided into two groups: hyperfractionation group and conventional segmentation group. In each group of 50 patients, the daily dose and total dose were similar in both groups. The total tumor volume was 65 Gy to 70 Gy/34 to 36 days. The hyperfractionated group was irradiated twice a day for 6 to 8 hours. Results In the hyperfractionated group, lesions disappeared, and the time for improvement of diet and relief of chest pain was better than that of the routine group. And radiotherapy response is light, the quality of life is good. The local recurrence and metastasis transfer rates were similar in both groups. We believe that hyperfractionated esophageal cancer is advisable.
