摘要 目的探讨性激素结合球蛋白(sex hormone-bindingglobulin,SHBG)在乳腺癌中的表达及意义。方法采用免疫组化EnVision法检测SHBG、AR、ER在83乳腺癌中的表达,每例标本中均包括浸润性乳腺癌(invasive breast carcino-ma,IBC)和原位癌(carcinoma in situ,CIS)组织。结果 CIS及IBC中SHBG表达与AR、ER无相关性,CIS中SHBG阳性68例(81.9%),IBC中阳性53例(61.9%),两者差异有显著性(P=0.007),AR、ER阳性乳腺癌中表达SHBG者临床分期低,差异有显著性(P值分别为0.049和0.013),SHBG阳性的乳腺癌中AR、ER均阳性者组织学分级低,差异有显著性(P=0.000)。结论 AR、ER阳性乳腺癌中SHBG具有抑制肿瘤增殖的作用,其表达缺失可能参与了激素依赖性乳腺癌的进程。
