发布时间:2018-12-26 12:34
【摘要】:目的研究FK506结合蛋白51(FK506Binding Protein51, FKBP51)在膀胱尿路上皮癌组织中的表达情况,并分析其与膀胱尿路上皮癌临床资料及病理特征之间的关系,以探索FKBP51在膀胱尿路上皮癌发生发展中的作用。 方法随机选取中南大学湘雅二医院病理科存档的膀胱癌蜡块标本中2011年1月至2013年12月期间手术方式为根治性膀胱术且病理证实为尿路上皮癌的标本65例,所有患者术前均未行化疗或放疗。其中男性49例,女性16例,年龄范围46.0-80.0岁,平均年龄64.2±8.6岁,中位年龄为66岁,年龄60岁:39例,60岁:26例。根据肿瘤大小:直径≤3cm:23例,直径3cm:42例。按2004年WHO组织学分级:低分级(高分化)乳头状尿路上皮癌41例,高分级(低分化)乳头状尿路上皮癌24例。按国际抗癌联盟2009年第7版TNM分期对组织标本进行分期,其中非肌层浸润性膀胱尿路上皮癌(包括Tis、Ta及T1期)18例,肌层浸润性膀胱尿路上皮癌(包括T2及其以上)47例。按淋巴结是否转移划分,其中转移16例,未转移49例。同时收集15例正常膀胱组织,为对照组。应用免疫组化技术检测FKBP51蛋白在所研究标本组织中的表达情况,并通过统计学方法分析其表达水平与膀胱尿路上皮癌临床资料及病理特征的关系。 结果FKBP51蛋白在所有正常膀胱组织及癌组织中均表达,但膀胱路上皮癌组织中表达比正常组织中表达明显增高(p0.01),其表达水平与性别、年龄及肿瘤大小无关(p0.05),与肿瘤临床分期(p0.05)、病理分级(p0.05)及淋巴结转移(p0.05)相关。 结论1FKBP51蛋白在正常膀胱组织中低表达,在膀胱尿路上皮癌组织中呈高表达,这种差异性表达提示FKBP51可能与膀胱尿路上皮癌的发生相关。 2.FKBP51蛋白在膀胱尿路上皮癌组织中表达水平与其病理分级和临床分期相关,提示FKBP51蛋白可作为评估膀胱尿路上皮癌恶性程度的生物学标志物,但具体特异性及敏感性有待进一步研究。

To explore the role of FKBP51 in the occurrence and development of bladder urothelial carcinoma. Methods from January 2011 to December 2013, 65 cases of bladder cancer were randomly selected from the paraffin specimens of Department of Pathology of Xiangya second Hospital of Central South University as radical cystectomy and pathologically proved urothelial carcinoma. All patients were not treated with chemotherapy or radiotherapy before operation. There were 49 males and 16 females with an age range of 46.0-80.0 years, with an average age of 64.2 卤8.6 years. The median age was 66 years. The median age was 60 years old: 39 cases, 60 years old: 26 cases. According to tumor size: diameter 鈮,
