摘要 目的检测ERα和ERβ在乳腺癌及癌旁组织内的表达,探讨其与乳腺癌发生、发展的关系。方法选取原发性可手术乳腺癌97例和癌旁组织61例,采用免疫组化S-P法测定ERα、ERβ的表达。结果ERα、ERβ均在细胞核内表达。癌旁组织内ERβ阳性表达率高于ERα(分别为91.8%和42.6%,P<0.01),两者差异无显著性(P>0.05)。ERβ在癌旁组织、腋窝淋巴结阴性(阳性率为81.6%)和阳性(阳性率为50.8%),三组中表达差异具有显著性(P<0.01),且ERβ在腋窝淋巴结阴性和阳性癌组织中表达的差异亦具有显著性(P<0.01)。ERα在三组内表达的差异无显著性(P>0.05)。结论ERβ、ERα均为细胞核受体。ERβ在癌旁和癌组织内广泛表达,且在癌旁组织内阳性表达率高于ERα。ERβ表达降低与乳腺癌腋窝淋巴结转移有因果关系;而ERα的表达与乳腺癌发生及腋窝淋巴结转移无关。
