摘要 目的探讨瘦素(leptin)、基质金属蛋白酶-2(MMP-2)在胃癌发展、浸润和转移中的作用及其相互关系。方法应用免疫组织化学SP法检测19例正常胃黏膜、19例慢性萎缩性胃炎伴肠化、17例不典型增生、15例早期胃癌、46例进展期胃癌组织中leptin、MMP-2表达情况。结果leptin随胃癌的发展阳性率逐渐增高(15.8%,36.8%,47.1%,53.3%,82.6%;P<0.01);leptin表达与组织学分级、浆膜浸润和淋巴结转移有关(P<0.05)。进展期胃癌组织中MMP-2阳性表达率80.4%显著高于正常胃黏膜、慢性萎缩性胃炎伴肠化、不典型增生、早期胃癌组(5.3%,26.3%,35.3%,53.3%;P均<0.05);MMP-2表达与组织学分级无关(P>0.05);与浆膜浸润、淋巴结转移有关(P<0.05)。leptin和MMP-2在胃癌组织中的表达存在显著正相关关系(rs=0.673,P<0.01)。结论leptin、MMP-2共同参与了胃癌的发展、浸润和转移。
