RESUMEN
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.
