摘要 目的探讨胃癌组织中环氧化酶-2(COX-2)、CD44v6和MMP-9蛋白表达在胃癌发生、发展过程中的作用。方法采用免疫组化Envision法检测104例胃癌患者癌组织中COX-2、CD44v6和MMP-9蛋白表达,并与28份健康胃黏膜组织比较。结果胃癌组织中COX-2、CD44v6、MMP-9蛋白阳性表达率分别为57.7%(60/104)、59.6%(62/104)和63.5%(66/104),正常胃组织中均呈低表达或不表达,两者有显著性差异(P<0.001);三者表达均与肿瘤浸润深度、临床分期及淋巴结转移呈明显正相关(P<0.05),而与患者性别、年龄及肿瘤分化程度无明显相关性;COX-2表达与CD44v6和MMP-9表达呈明显正相关。结论COX-2、CD44v6和MMP-9的过表达可促进胃癌的浸润、转移,三者具有正协同作用;COX-2、CD44v6和MMP-9联合检测可用于判断胃癌生物学行为。
