Foxp3在乳腺癌组织中的表达及其临床意义

目的:研究乳腺癌组织中Foxp3+细胞浸润和Foxp3蛋白的表达及其临床意义。方法:160例乳腺癌以及22例癌旁正常乳腺组织取自上海市黄浦区中心医院(2005年1-12月),免疫组化检测乳腺癌组织和癌旁组织中Foxp3+淋巴细胞浸润和Foxp3蛋白的表达,分析它们与乳腺癌患者病理特征以及ER、PR、P53、Bcl-2、HER-2表达间的关系。结果:乳腺癌间质Foxp3+细胞浸润和实质Foxp3蛋白表达阳性率均高于癌旁组织(50.6%vs 13.6%,P<0.05;38.1%vs 4.5%,P<0.05);乳腺癌Foxp3+细胞浸润和Foxp3蛋白表达间无相关性(P>0.05)。乳腺癌间质Foxp3+细胞浸润与乳腺癌淋巴结转移、组织学分级、P53过表达呈正相关(P<0.05);癌实质Foxp3蛋白表达与肿瘤淋巴结转移、组织学分级、pTNM和P53过表达呈正相关(P<0.05);但两者与ER、PR、HER-2、Bcl-2过表达均无关(P>0.05)。单因素分析提示,乳腺癌中Foxp3表达和Foxp3+细胞浸润都是影响5年生存率的因素;多因素分析结果表明,Foxp3的表达不是影响乳腺癌5年生存率的独立预后指标。结论:乳腺癌组织高表达Foxp3蛋白可作为一个潜在的乳腺癌生物标记物,但不是一个独立的预后指标。

Expression and clinical significance of Foxp3 in breast carcinoma tissues

Objective:To investigate the infiltration of Foxp3+ cells and expression of Foxp3 protein in breast carcinoma tissues and their clinical significance.Methods: One hundred and sixty breast carcinoma and 22 paracancerous tissues(who had been diagnosed in Shanghai Huangpu Center Hospital from Jan.2005 to Dec.2005) were included in present study.The infiltration of Foxp3+ cells and expression of Foxp3 protein in breast carcinoma and paracancerous tissues were detected by immunohistochemistry,and their relations...
