Comparion of the postoperative radiotherapy of rectal carcinoma and with only operation

摘要: 目的　探讨直肠癌术后追加放疗是否降低局部复发率。方法　全部病例采用Mile's和Dixon术式, 并随机分为术后放疗组 5 8例和单纯手术组 4 5例 ;术后放疗组设盆腔后野和两侧野照射, 照射剂量为 4 5Gy/4 .5～ 5周, 缩野追加 10～ 15Gy。结果　术后放疗组 5 8例 1/ 2、1、2年的局部复发率为 1.72 %、5 .17%、12 .0 7% ;单纯手术组为 8.89%、17.78%、35 .5 6 %, 两组 1年、2年局部复发率有显著差异。结论　直肠癌手术后放疗组局部复发率显著低于单纯手术组
