ABSTRACT
Objective To investigate the expression and significance of bin 1,C-myc in bladder urothelial carcinoma.Methods SP method was used to detect the expression of bin 1,C-myc protein in paraffin specimens from bladder urothelial carcinoma of 84 cases and mucosa of 11 cases,and its relationship with clinical pathological charac-teristics was analyzed.Results The positive expression rate of bin1 in normal bladder tissues was 81.81%,that in bladder urothelial carcinoma was 46.43%,the difference was not significant (χ2 =4.873,P=0.051).No expression of C-myc was observed in normal bladder tissue ,the positive expression rate of C-myc in bladder urothelial carcinoma was 52.38%,the difference was statistically significant (χ2 =10.733,P=0.001).The expression of bin1 in invasive bladder urothelial carcinoma was significantly lower than the non-infiltrating type(χ2 =7.685,P =0.007),with increased histological grade and UICC stage ,the positive rate of bin1 expression decreased (χ2 =15.817,P=0.000;χ2 =11.104,P=0.010).The expression of C-myc had no relationship with the histological classification ,histological grade and UICC stage .Correlation analysis showed that the expression of bin 1 was negatively correlated with histologi-cal classification,histological grade and UICC stage (r=-0.302,P=0.005;r=-0.411,P=0.000;r=-0.302, P=0.005).With the increased expression of bin1,C-myc expression decreased,but the difference was not statistical-ly significant.Conclusion Low expression of bin1 or loss of bin1expression were associated with the progression of bladder urothelial carcinoma , the expression of C-myc was related with bladder urothelial carcinoma lesions .The results suggest that bin1 may be predictive factor for prognosis of urinary bladder urothelial carcinomas ;bin1,C-myc may be viewed as molecular targets for tumor chemotherapy .
