Abstract： 目的探讨中下段直肠癌盆腔侧方淋巴结转移(简称侧方转移)的规律和预后.方法对 1990～ 2001年经根治性切除证实侧方转移的 20例中下段直肠癌患者的临床资料进行回顾性分析.结果 85.0%( 17/20)的患者为直肠系膜和 /或根部淋巴转移加侧方转移, 15.0%( 3/20)的患者为单纯侧方转移.侧方转移率依次为闭孔动脉 45.0%( 9/20)、髂内动脉 40.0%( 8/20)、髂总动脉 20.0%( 4/20)、髂外动脉 15.0%( 3/20)和腹主动脉分叉淋巴结 5.0%( 1/20). 75.0%的患者发生术后远处转移或远处转移合并盆腔局部复发,其中 83.3%发生于术后 2年内.患者平均生存期 21.6个月, 术后 3年、 5年生存率分别为 16.7%和 0.结论中下段直肠癌侧方转移不仅是盆腔局部病变,还可能是属于全身病变的一部分,提示直肠癌远处转移发生的可能性.
