摘要 为探讨乳腺肿瘤组织中细胞外基质金属蛋白酶 -2 (MMP 2 )和组织基质金属蛋白酶抑制剂 -2 (TIMP 2 )的表达情况 ,研究及其与乳腺肿瘤发生、发展中的生物学意义并观察其与乳腺癌浸润及转移的相关性 ,作者采用免疫组化方法检测 5 8例乳腺浸润性导管癌及 2 0例乳腺纤维腺瘤的组织标本中MMP 2和TIMP 2的表达情况并进行对比观察。结果示 5 8例乳腺癌和 2 0例乳腺纤维腺瘤的组织中MMP 2的表达分别为 43 .1%(2 5 / 5 8)和 10 %(2 / 2 0 ) ;TIMP 2的表达分别为 5 5 .17%(3 2 / 5 8)和 90 %(18/ 2 0 )。MMP 2的高表达与肿瘤的病理分级、淋巴结转移呈正相关 ,TIMP 2阳性表达与肿瘤的病理分级、淋巴结转移呈负相关。提示MMP 2和TIMP 2的表达与乳腺癌的浸润和淋巴结转移密切相关 ,MMP 2阳性表达率上升和 /或TIMP 2阳性表达率下降 ,表示乳腺癌浸润及转移能力增强 ,联合检测两指标有助于乳腺癌浸润转移和预后的判断。
