Objective: To evaluate the effect of accelerated fractionation radiation therapy for esophagus carcinoma.
目的：评价加速超分割放射治疗食管癌的疗效。方法：食管鳞癌98例随机分为常规组和加速超分割组。
Continuous hyper& fractionation accelerated radiation therapy may worse the radiation esophagus injury. 70% will get level 2-3 sharp radiation esophagitis.
缩短总疗程的全程加速超分割放疗，可使放射性食管损伤增加，70%患有2&3级急性放射性食管炎，而加量野（小野）食管在放射野内的急性放射性食管炎的发病率为100%。
Conclusions Compared with conventional fractionation radiotherapy, 3DCRT was able to improve the local control rate of esophageal carcinoma, with tolerable acute and late radiation side effects.
结论3DCRT能明显改善食管癌的局部控制率和生存率，近期放射反应及远期放射损伤均可耐受。
Comparison between conventional fractionation, late-course accelerated hyperfractionation and external beam combined with intracavitary radiation in the treatment of locally moderate and advanced esophageal carcinoma
