膀胱癌组织中乳腺癌扩增基因1的表达及其意义

Expression of AIB1 in bladder cancer and its significance

目的 探讨膀胱癌组织中乳腺癌扩增基因1（AIB1）基因的表达及其临床意义.方法 收集30例因膀胱癌行全膀胱切除术或经尿道膀胱癌电切术的标本,术前病理检查均为尿路上皮癌,采用免疫组织化学方法检测膀胱癌组织和癌旁组织中AIB1的表达情况.结果 膀胱癌组织AIB1的阳性表达率高于癌旁组织[43.3％（13/30）比3.3％（1/30）,x2=4.316,p＜0.05],高分期膀胱癌组织AIB1的阳性表达率高于低分期膀胱癌组织[T1、T2、L期分别为25.0％（2/8）、42.9％（6/14）、62.5％（5/8）,x2=4.623,P＜0.05].AIB1的表达与患者性别、年龄、肿瘤数目和病理分级无明显相关性（均P＞0.05）.结论 AIB1与膀胱癌关系密切,有可能成为判断膀胱癌预后的重要指标.

Objective To investigate the expression of AIB1 protein in bladder cancer and its significance.Methods 30 cases of bladder cancer and 30 adjacent normal tissues were collected from 30 patients underwent radical or TURBt.The level of AIB1 protein expressed in these tissues were detected by immunohitochemical method.Results The positive rate of AIB1 protein in bladder carcinoma was higher than that in the normal tissues [43.3 ％ （13/30） vs 3.3 ％ （1/30）,x2 =4.316,P ＜ 0.05].The positive rate of AIB1 in T3 stage was higher than that in T1 or T2 stage [62.5 ％ （5/8） vs 25.0 ％ （2/8）,42.9 ％ （6/14）,x2 =4.623,P ＜ 0.05].No correlation was found between the expression of AIB1 protein and the sex,age,multiplicity or pathological grade （P ＞ 0.05）.Conclusions There is a close relationship between AIB1 and bladder cancer.AIB1 might have great value on the prognosis of patients with bladder cancer.
