| 摘 要： | 目的:观察后程加速与常规放疗治疗食管癌结果和毒副反应。方法:食管癌患者80例分为两组:(1)常规分割组:采用常规放疗42例,常规分割2Gy/次,1次/天,5次/周,DT:44Gy/22次/4.5周完成;根据CT片再在模拟机下定位,设两背后斜野或前后对穿斜野,完全避开脊髓,追加剂量DT:20～26Gy/10～13次/2～3周完成;(2)适形放疗组:采用三维适形放疗38例,以真空体模固定,仰卧体位,先常规放疗,方法同常规组,DT:440Gy/22次/4.5周完成,然后采用三维适形放疗,CT定位,3Gy/次,1次/天,5次/周,追加剂量DT:27～33Gy/9～11次/2～3周完成。结果:随访率97.5%,常规组和三维适形组1、2年局部控制率分别为42.8%、35.7%和73.6%、55.3%,其中1年局部控制率两组差异有统计学意义(P<0.01),1、2年生存率分别为52.3%、35.7%和68.4%、52.6%,常规组:急性放射性食管炎0级15例(35.7%),1～2级18例(42.3%),3级9例(22.0%),无4级损伤。放射性肺炎0级19例(45.2%)、1～2级16例(38.0%),有3级以上的8例(1...

| Abstract: | Objective:To compare the efficacy and complications of late course accelerated three-dimensional conformal radiotherapy (3DCRT) with those of conventional radiotherapy (CR) for esophageal carcinoma. Methods:Eighty patients with esophageal carcinoma were randomized into 2 groups:conventional fractionated radiation therapy group (group CR-42 patients )and late course accelerated three-dimensional conformal radiotherapy group (group 3DCRT-38 patients ) ,In group CR,42 patients received a dose of 66-70 Gy at 2 ... |
