| 摘 要： | 目的通过检测S-100A4和基质金属蛋白酶2(MMP-2)在胃癌组织中的表达,探讨其在胃癌侵袭和转移中的作用。方法采用SP法检测S-100A4和MMP-2在91例胃癌组织以及91例配对切缘正常黏膜和72例转移淋巴结组织中的表达,分析其与胃癌临床病理特征的关系。结果 S-100A4在切缘正常黏膜、原发癌和淋巴结转移灶中的表达率分别为12.1%、29.7%和29.2%;MMP-2在相应组织中的表达率为20.8%、58.2%和59.7%。S-100A4和MMP-2在胃癌组织中表达均明显高于正常黏膜组织(P<0.05),而且其表达与肿瘤的浸润程度密切相关。S-100A4与MMP-2在胃癌组织中的表达呈正相关(r=0.27,P<0.05)。结论 S-100A4和MMP-2的表达与胃癌的侵袭密切相关,联合检测S-100A4和MMP-2表达有助于判定胃癌临床病理特征及预后。
