摘要 目的:探讨在我院未行全直肠系膜切除术(total mesorectal excision,TME)后直肠癌局部复发的模式。方法:搜集我院2002年1月至2011年4月,93例直肠癌术后病人的资料(包括CT/MRI旧片),由两名有经验的放疗科医生对其影像所显示的局部复发部位重新独立审阅,并结合临床资料进行分析。结果:随访率为95.7%。1,2,3年总生存率分别为54.8%、23.7%、10.8%。单因素统计分析结果表明原发肿瘤位置、浸润深度、转移淋巴结数、初治术后分期、远处转移、复发时间与预后相关。其中远处转移及复发时间是影响未行TME术后局部复发直肠癌患者预后的独立因素。局部复发模式中,主要的复发盆腔亚区为:直肠系膜区(46例,49.4%),前盆腔区(30例,32.2%),后盆腔区(24例,25.8%),侧位盆腔区(15例,16.1%),低位盆腔区(11例,11.8%);主要的淋巴引流复发区域:髂内血管旁(15例,16.1%),髂外血管旁(6例,6.4%),髂总血管旁(6例,6.4%)。结论:直肠系膜区、前盆腔区、后盆腔区是未行TME术式后盆腔内主要的复发高危区域;而髂内血管旁则是常见的区域淋巴结复发部位。
