目的:探讨miR-200c在胃癌组织中的表达水平与胃癌患者临床病理特征及无病生存期(diease free survial,DFS)的关系。方法:收集河北医科大学第四医院普外科2012年5月至2013年1月64例胃癌手术切除的标本及相关临床资料,采用实时荧光定量PC...目的:探讨miR-200c在胃癌组织中的表达水平与胃癌患者临床病理特征及无病生存期(diease free survial,DFS)的关系。方法:收集河北医科大学第四医院普外科2012年5月至2013年1月64例胃癌手术切除的标本及相关临床资料,采用实时荧光定量PCR技术检测miR-200c在胃癌组织和配对癌旁非癌组织中的表达。回顾性分析miR-200c表达水平与胃癌患者的临床病理特征及DFS相关性。结果:胃癌组织中miR-200c的表达水平显著低于癌旁非癌组织(3.29 vs 5.91,P<0.01)。miR-200c的表达水平与肿瘤TNM分期、浸润深度、转移和脉管瘤栓呈显著负相关(均P<0.01)。miR-200c高表达组患者中位DFS明显长于低表达组患者(22.0 vs 13.5个月,P<0.01),其表达水平与患者DFS呈正相关(P<0.01)。结论:miR-200c在胃癌组织中低表达,其表达水平与肿瘤TNM分期、肿瘤浸润深度和脉管瘤栓呈负相关,与DFS呈正相关,在胃癌的发生发展及预后中具有重要作用。展开更多
