  • 摘要:   目的  探讨胃癌根治术后切缘阳性患者的临床病理特征及其对预后影响。  方法  回顾性分析河北医科大学第四医院2011年1月至2016年1月收治的胃癌根治术后切缘阳性患者的临床病理资料。按1∶2随机数法选取同期收治的切缘阴性患者,比较阳性和阴性切缘患者的一般临床病理学特征及预后情况。  结果  共纳入73例切缘阳性患者,与同期纳入的146例切缘阴性病例比较,阳性组的肿瘤直径更大、更多位于贲门或全胃,组织学类型更差、Lauren分型趋于弥漫型、Borrmann分型多为Ⅲ~Ⅳ型、肿瘤浸润深度以T4a~4b为主、pTNM分期更晚,脉管浸润率及淋巴结转移率也更高,同时术者经验、手术方式的差异也与阳性切缘发生有关(均P<0.05)。全组共有205例患者获得完整随访,两组患者5年总生存(overall survival,OS)率及无进展生存(progression-free survival,PFS)率均有显著性差异(23.19% vs. 58.82%,15.94% vs. 47.06%,均P<0.001)。Cox多因素分析显示,切缘状态(P=0.012)、pTNM分期(P=0.023)及术后综合治疗(化疗/化疗联合放疗)(P<0.001)是影响胃癌预后的独立因素。  结论  胃癌根治术后切缘状态与多种临床病理特征相关,切缘阳性患者预后较差。
