摘要
目的 观察雌激素受体β(ER-β)在膀胱癌中的表达及其与临床病理特征的关系,探讨其临床意义.方法 采用免疫组织化学SP法检测ER-β蛋白在146例膀胱尿路上皮癌和25例正常膀胱黏膜中的表达.结果 ER-β蛋白在膀胱癌组织中阳性表达率为44.5%,在正常膀胱黏膜组织阳性表达率为20.0%,差异有统计学意义(P<0.05).ER-β的表达率随着膀胱癌病理分级和临床分期的升高而增高(P<0.05),而且与患者性别明显相关,女性阳性率显著高于男性患者(P<0.05).结论 ER-β在膀胱癌组织中表达有明显的性别差异,且与膀胱癌的分化和浸润性进展密切相关,提示ER-β蛋白可能在膀胱癌的发生发展中起重要作用.
Objective To investigate the expression of estrogen receptor beta (ER-β) in bladder urothelial carcinoma and to explore its clinical significance.Methods Immunohistochemical SP method was employed to detected the expression of ER-β in bladder cancer tissue ( 146 cases) and the normal controls (25 cases).In addition,clinicopathological data of them were analyzed.Results The positive expression rate of ER-β in bladder cancer tissue was 44.5%,but low positive expression rate (20.0% )was found in normal bladder tissue.The expression of ER-β was markedly associated with tumor pathological grade and clinical stage ( P〈0.05).Moreover,the expression of ER-β was observed more frequently in female (59.6%) than male (37.4%) (P〈0.05 ).Conclusion The sex difference in expression of ER-β is associated with differentiation and invasion in bladder urothelial carcinoma,it implies that ER-β might play important roles in the development and progression of bladder cancer.
