摘要 目的观察窖蛋白(Caveolin-1,Cav-1)在正常乳腺组织、良性增生性乳腺病及乳腺癌中的表达及其与乳腺癌临床病理特征的关系。方法采用免疫组化SP法检测10例正常乳腺组织、15例良性增生性乳腺病和48例乳腺癌组织中Cav-1的表达,分析Cav-1在不同乳腺病变中表达的差异。结果 Cav-1在正常乳腺组织、良性增生性乳腺病及乳腺癌中的阳性率分别为40%、46%和100%,平均表达强度积分(x珋±s)分别为0.90±0.83、0.93±1.16和6.24±2.18。其在正常乳腺组织与良性增生性乳腺病之间表达差异无统计学意义(P>0.05);在正常乳腺组织、良性增生性乳腺病与乳腺癌之间表达差异具有显著性(P<0.01);在乳腺癌不同组织学类型、病理分级、临床分期、细胞增殖指数(MIB-1/Ki-67)和有无淋巴结转移中阳性率和表达强度差异均无显著性(P>0.05)。结论 Cav-1在正常乳腺组织及良性增生性乳腺病中呈低表达,在乳腺癌中呈高表达,表明Cav-1与乳腺癌的发生密切相关,但与乳腺癌的组织学类型、病理分级、临床分期、有无淋巴结转移和细胞增殖指数(MIB-1/Ki-67)无明显相关性。
