摘要
1987年6月至1988年12月，我院对食管癌患者74例予以单纯放疗，60Cor线与8MV—X线各治疗37例。病人情况、治疗方法及剂量两组相似，结果加速器照射组在减轻症状，改善进食、加速肿瘤消退、提高近期疗效方面均优于钴组，而3年5年生存率无显著性差异。作者认为凡经济情况允许者宜选择加速器照射。为实施合理放疗、提高疗效，治疗前应予以胸部CT扫描，并适当增大照射野宽度及长度，配合内照射放疗或／及化疗。
From Jun.1987 to Dec. 1988,74 patients with esophageal carcinoma were given radiation teletherapy alone. Each half of them were treated with cither 60Co unit or 8MV linear accelerator. The patients' conditions,treatment schedules, and doses given were similar in both groups.The treatment results were superior in linear accelerator group on abating symptoms, increasing appetite, reducing tumor volume and improving short-term survival rate, but there were no obvious differences in 3- and 5-year survival rates. The authors suggested that in order to improve treatment results, it is necessary to have a chest CT Scanning before radiotherapy, to treat with a linear accclerator if there is financially permitted, to irrad iate on larger fields and to treat accompanied with intralumenal radiation therapy and/or chemotherapy.
