摘要: 目的 探讨后期加速超分割术前放疗经腹会阴手术治疗局部晚期直肠癌的疗效。方法 4 6例局部晚期直肠癌随机分为加速后期超分割术前放疗经腹会阴手术组 2 2例, 单纯腹会阴手术组 2 4例。术前放疗组先行盆腔前后野常规照射 36Gy/ 4周, 后行盆腔两侧野超分割照射, 2 4～ 2 6Gy/ 2周, 总DT为 6 0～6 2Gy, 休息 4～ 5周后手术。单独手术组术前不放疗。 结果 术前放疗组淋巴结转移率、局部复发率显著低于单纯手术组。手术切除率、3年、5年生存率显著高于单纯手术组。结论 后期超分割术前放疗对可手术的局部晚期直肠癌是有意义的Abstract: Objective To discuss the long term curative effect resulting from the treatment of local late-stage carcinoma of the abdominal perineum.
