摘要 目的:探讨基质金属蛋白酶-9(MMP-9)在人乳腺癌及癌旁组织中的表达和临床意义及孕激素受体(PR)对MMP-9的调节作用。方法:应用免疫组化SP法,检测MMP-9在乳腺癌组织、癌旁非典型增生腺体及普通型增生腺体中的表达和PR在癌组织中的表达。结果:MMP-9在乳腺癌、癌旁非典型增生腺体及普通型增生腺体中阳性表达率分别为92%、72%和58%;强阳性率分别为44%、4%和0;在PR阳性病例的癌组织中,MMP-9的阳性表达率(>3分者)为60%,而在PR阴性病例中,其阳性率为92%。结论:MMP-9对乳腺癌的发生、发展、浸润和转移过程可能起着促进及加强作用;且MMP-9在癌组织中的表达可能受到孕激素及其受体的负相关调节作用。
