摘要
目的探讨尿激酶型纤溶酶原激活剂(uPA)和基质金属蛋白酶(MMP-9)在乳腺癌及肿瘤周围组织中的表达与乳腺癌侵袭、转移的关系。方法应用免疫组化Envision法检测50例乳腺癌及20例癌旁组织中uPA和MMP-9蛋白的表达情况,并分析其相关性及与临床病理特征进行比较。结果乳腺癌组织中uPA的阳性表达率为60%(30/50),MMP-9的阳性表达率为66%(33/50),显著高于癌旁组织(P<0.01),在乳腺癌组织中uPA、MMP-9蛋白表达之间存在显著正相关(r=0.630,P<0.01)。uPA、MMP-9表达与淋巴结转移、临床分期显著相关(P<0.05),与患者的年龄、肿瘤大小无明显相关性(P<0.05)。结论乳腺癌组织中存在uPA、MMP-9的高表达;uPA蛋白可通过诱导MMP-9蛋白的表达上调,促进乳腺癌侵袭、转移。
