摘要 目的探讨基质金属蛋白酶-3(MMP-3)及其抑制物组织基质金属蛋白酶抑制剂-3(TIMP-3)在胃癌中的表达情况及其临床意义。方法通过免疫组化的方法检测95例胃癌组织原发灶及其淋巴结转移灶中MMP-3和TIMP-3的表达情况,并分析其与胃癌患者临床病理特征的关系。结果 MMP-3在淋巴结转移灶中的阳性率(74.1%)显著高于原发灶中的阳性率(55.8%,<0.05),而TIMP-3在转移灶中的阳性率(37.7%)显著低于原发灶中的阳性率(66.3%,<0.05)。MMP-3的表达与临床分期呈正相关(=0.45,<0.05);TIMP-3的表达与临床分期呈负相关(=-0.39,<0.05)。结论 MMP-3和TIMP-3的表达与胃癌淋巴结转移密切相关,且转移灶癌细胞MMP-3的表达明显增强,TIMP-3的表达明显下降,可作为临床判断胃癌恶性程度、淋巴结转移的重要参考指标。
