摘要
目的:观察Her-2基因在胃癌组织中的表达,探究Her-2与胃癌发生的关系。方法:采用组织芯片技术、免疫组织化学(IHC)技术及荧光原位杂交(FISH)技术检测60例患者胃癌组织中Her-2蛋白的表达情况,分析Her-2基因扩增与肿瘤的侵袭、转移及预后的相关性。结果:Her-2蛋白在不同分化程度的胃癌组织中的表达量不同,43例(71.67%)阳性表达Her-2蛋白,其中12例弱阳性(+)表达,17例中等阳性(++)表达,14例强阳性(+++)表达。运用FISH技术检测7例胃癌组织中的Her-2基因扩增情况,其中3例为IHC检测强阳性(+++)表达,3例为中-弱阳性(+~++)表达,1例阴性(-)。结论:Her-2蛋白在不同分化程度的胃癌组织中表达不同,虽然尚未证明其确切的相关性规律,但以此为出发点研究胃癌的发生发展及恶性进展具有重大的意义。
