摘要: 目的:探讨基质金属蛋白酶(MMP-2、MMP-9)和金属蛋白酶组织抑制剂(TIMP-1)在胃癌中的表达及与临床病理特点和预后的关系。方法:应用免疫组织化学技术和形态定量分析方法。结果:MMP-2、MMP-9在胃癌基质中有表达,明显高于癌旁正常组织(P<0.01);TIMP-1分布于癌巢周边的基质中, MMP-2、MMP-9及TIMP-1在胃癌中的表达程度与患者的年龄、肿瘤大小、病理分级无关,而与患者的淋巴结转移情况相关(P<0.05)。结论:MMP-2、MMP-9和TIMP-1与胃癌的临床病理特点和转移预后密切相关,可作为判定胃癌生物学行为和预后的重要指标。

Abstract: Objective To study the relationships of expressions of MMP-2, MMP-9, TIMP-1 in gastric carcinoma and pathological characteristics in clinic metastasis and prognosis. Methods Immunohistochemistry and morphologic quantitative analysis were used. Results Expression levels of MMP-2 and MMP-9 in gastric carcinoma matrix were markedly higher than those of pericarcinoma normal tissues (P<0.01). TIMP-1 expressed in pericarcinoma matrix. There were no any rel ationships between the expression levels of MMP-2, MMP-9, TIMP-1 in gastric carcinoma and patients′ age, tumor size, pathological grading, but there was obvious relationship between expression levels of MMP-2, MP-9, TIMP-1 and lymphnode metastasis (P<0.05). Conclusion There are close relationships between the expressions of MMP-2, MMP-9, TIMP-1 in gastric carcinoma and pathological characteristics in clinic metastasis and prognosis. They may be used as important indexes to judge the biological behavior and prognosis of gastric carcinoma.
