摘要 目的观察胃癌组织中基质金属蛋白酶-9(MMP-9)和人表皮生长因子受体-2(HER-2)的表达,探讨其与患者预后的关系。方法选择63例胃癌患者,取胃癌组织和癌旁正常组织,应用免疫组化法检测MMP-9和HER-2表达,对随访资料进行生存分析。结果 MMP-9、HER-2在胃癌组织中的阳性率均高于癌旁正常组织(P均<0.05)。胃癌组织中MMP-9表达与肿瘤浸润深度、TNM分期、淋巴结转移和Ki-67增殖指数有关(P均<0.05),HER-2表达与淋巴结转移有关(P<0.05);MMP-9与HER-2的表达呈正相关(r=0.271,P=0.032)。MMP-9阳性与阴性表达者的中位生存时间分别为34、47个月(P<0.05);HER-2阳性与阴性表达者的中位生存时间分别为18、40个月(P<0.05)。结论 MMP-9和HER-2参与了胃癌的发生发展,二者联合检测有助于判断胃癌患者的预后。
