摘要
目的 研究胃癌组织中survivin基因的mRNA和蛋白表达情况及其与临床病理参数的关系。方法 应用原位杂交方法和免疫组化SP法检测 5 4例胃癌 ,34例胃良性病变 ,2 0例胃正常组织标本中survivin基因mRNA及蛋白的表达。并对其与临床病理因素和二者的关系进行分析。结果 Survivin蛋白表达阳性率在胃癌、良性疾病组织和正常组织分别为 87 0 % (47/ 5 4 )、 2 3 5 % (8/ 34)和 15 % (3/ 2 0 ) ;SurvivinmRNA阳性率为 79 6 % (43/ 5 4 )、 2 3 5 % (8/ 34)和2 0 % (4/ 2 0 )。胃癌组远大于正常胃组织和良性疾病组 ,而正常胃组织与胃良性疾病组之间差异无显著性。SurvivinmRNA与蛋白在胃癌中的表达呈正相关 (rs=0 6 79,P <0 0 5 )。且其阳性率高低与性别、年龄、组织学类型无关 ;而与淋巴结转移、TNM分期、组织学分级有关。结论 SurvivinmRNA与蛋白在胃癌中表达较高 ,且与淋巴结转移、TNM分期、组织学分级有关 ,它可作为评估胃癌生物学行为和判断预后的生物学指标。
