摘要
目的:探讨p27和ILK在胃癌及癌前病变中的表达及其与胃癌病理参数之间的关系。方法:用免疫组化技术(SP法)对正常胃黏膜(normal gastric mucosa,NGM)、慢性浅表性胃炎(chronic superficial gastritis,CSG)、慢性萎缩性胃炎(chronic atrophia gastritis,CAG)伴肠上皮化生、慢性萎缩性胃炎伴非典型增生各20例和胃癌(gastric carcinoma,GC)60例标本进行免疫组织化学染色,分析p27和ILK的表达与胃癌临床和病理的关系。结果:p27和ILK表达阳性率分别为:NGM组100%和5%,CSG组85%和10%,CAG伴肠化组70%和20%,CAG伴非典型增生组45%和30%,胃癌组38.3%和40%。胃癌组和CAG伴非典型增生组p27阳性率显著低于其他组(P<0.05),ILK阳性率则显著高于其他组(P<0.05)。p27和ILK在胃癌中的表达与肿瘤分化程度、浸润深度及肿瘤临床分期相关,p27蛋白的表达还与有无淋巴结转移相关。p27和ILK在胃癌中的表达呈显著负相关(r=-0.768,P<0.05)。结论:检测胃癌组织中p27和ILK的表达有助于判断肿瘤的进展程度,两者联合检测有助于判断肿瘤预后。
