摘要 目的:探讨2种新辅助放化疗在中晚期直肠癌全直肠系膜切除术的作用。方法:将2002年7月至2006年12月入院的78例T3、T4期低位直肠癌随机分为A、B两组,每组39例。全部给予放疗,每次2Gy,总剂量45-50Gy,每周5次。A组同时辅以5-氟尿嘧啶(F-FU)、亚叶酸钙治疗(LV),B组同时辅以希罗达(Xeloda)治疗。放疗结束休息6周后进行手术。手术均按全直肠系膜切除术操作规范进行。结果:全部病人按计划完成新辅助放化疗,其中11例肿瘤完全消失,未行手术。67例施行了根治性切除术,65例为保肛手术。2例为腹会阴切除术。病理结果显示10例肿瘤消失(T0)。总的肿瘤消失为21例。T2N013例,T3N026例,T2-3N018例,无T4期。共52例(66.67%)达到降期(down staging)。全组随访6-42个月。无局部复发,4例肺转移,总复发率5.13%,无死亡,无瘤生存和无复发,生存率均为94.87%。结论:新辅助放化疗与全直肠系膜切除术操作规范相结合有效地达到肿瘤降期的目的,肿瘤缩小,切除率和保肛率均明显增加,降低了复发的风险。但选择合适的化疗药物可以降低副反应的发生率。
