摘要 目的探讨Survivin和rac1蛋白在正常胃和胃癌组织中的表达及其与胃癌生物学行为的关系。方法应用链酶亲和素-生物素过氧化物酶复合物(SABC)免疫组化法检测65例胃癌及癌旁6cm处正常胃黏膜组织中Survivin和rac1蛋白的表达,并分析其与胃癌临床、病理参数之间的关系。结果 (1)Survivin蛋白在癌旁正常胃黏膜组织中染色均为阴性,在胃癌组织中52.3%染色阳性(P<0.01);rac1蛋白染色阳性率在胃癌组织中(75.4%)显著高于癌旁正常胃黏膜组织(21.5%)(P<0.01);(2)随胃癌组织分化程度的降低、浸润深度的增加、TNM分期的升高及淋巴结和远处转移的发生,Survivin和rac1蛋白的染色阳性率明显升高(P<0.05);(3)Survivin阳性胃癌组织中的rac1蛋白表达水平显著高于Survivin阴性者(P<0.01)。结论 Survivin和rac1的表达与胃癌的生物学行为密切相关,对胃癌组织中Survivin和rac1的联合检测有助于预测胃癌患者的预后。
