摘要 摘 要:目的 研究p53和Survivin基因蛋白在胃癌中的表达,了解其临床意义.方法 用免疫组织化学SP法检测106例胃癌组织的p53和Survivin基因蛋白的表达水平,并选择同一时间段30例胃黏膜异型增生病例和30例正常胃黏膜病例进行对照研究,对患者随访5年.结果 p53蛋白的阳性率,胃癌中为86.8%,胃黏膜异型增生为30.0%,正常胃黏膜呈阴性表达 p53蛋白表达与组织类型无关.Survivin阳性率,胃癌中82.1%,胃黏膜异型增生为26.7%,呈弱表达 正常胃黏膜为1.3%,呈弱表达,Survivin蛋白表达与组织类型无关.淋巴结转移组的p53蛋白及Survivin蛋白均相应高于无淋巴结转移组 随访结果提示,随着p53蛋白和Survivin蛋白阳性率的增高,胃癌患者的生存期缩短.结论 p53和Survivin基因蛋白在胃癌中高表达,此两种蛋白高表达,癌细胞易转移,患者预后差,生存期短.
