ABSTRACT
Objective To evaluate the expressions of TBX2 and MDM2 protein in urothelial carcinoma of bladder.Methods The expressions of TBX2 and MDM2 protein were examined by immunohistochemistry EnvisionTM Plus method in 90 cases of urothelial carcinoma of bladder and 20 cases of normal bladder mucosa tissue.Results The positive rate of TBX2 and MDM2 protein was 0 in normal bladder mucosa tissues.The positive rate of TBX2 in urothelial carcinoma of bladder was 65.6% (59/90).With the increased of TBX2 expression degree,the carcinoma tissue was worse cell differentiation,later clinical stage,more prone to recurrence (P < 0.01).The positive rate of MDM2 in urothelial carcinoma of bladder was 31.1%(28/90).With the decreased of carcinoma tissue differentiation degree,the positive rate of MDM2 was increased (P < 0.01).The positive rate of MDM2 in recurrence patients was 57.5% (23/40),in non-recurrence patients was 10.0% (5/50),there was statistical difference (P < 0.01).The positive rate of MDM2 in pTNM stage Ta-T1 was 0,in pTNM stage T2-T3 was 73.7% (28/38),there was statistical difference (P <0.01).There was positive correlation between the expression of TBX2 and MDM2 in carcinoma tissue (r =0.487,P < 0.05).Conclusions The over expression of TBX2 and MDM2 protein may closely associated with aggressive biological behavior and recurrence in urothelial carcinoma of bladder.Combined analysis of TBX2 and MDM2 may provide a theoretical basis for prognostic information and treatment of patients with urothelial carcinoma of bladder.
