作者从1970年6月至1977年12月用放射线和博来霉素治疗食管癌74例,进行了治疗前后的X线片改变与预后关系的研究和分析。年龄从44岁至83岁,平均年龄男性69岁,女性72岁,男与女之比为7∶1。X线部位胸中段占66%,胸下段占24%。病变长度5-10厘米者占62%,5厘米以下者占16%,10厘米以上者占22%。其病型:溃疡型占57%。锯齿型为20%,肿瘤型为14%,漏斗型为8%,除1例为腺癌外,余均为鳞癌。放射治疗用6MeV的高能X线,设前后二野对穿照射,每次肿瘤量200拉德,每周五次;或250拉德
From June 1970 to December 1977, the authors treated 74 cases of esophageal cancer with radiation and bleomycin, and studied and analyzed the relationship between X-ray changes and prognosis before and after treatment. The age ranges from 44 to 83 years. The average age is 69 years for men and 72 years for women. The ratio of men to women is 7:1. The X-ray site accounted for 66% of the mid-chest and the lower chest was 24%. Lesions with a length of 5-10 cm accounted for 62%, those below 5 cm accounted for 16%, and those above 10 cm accounted for 22%. The disease type: ulcers accounted for 57%. The zigzag type was 20%, the tumor type was 14%, and the funnel type was 8%. Except for 1 case of adenocarcinoma, the rest were squamous cell carcinomas. 6MeV high-energy X-rays for radiotherapy, with front and back field radiation, 200 rads per tumor, five times per week; or 250 rads
