Abstract:
Objective To investigate the correlation between the expression of Cyclin D1,Rb and clinicopathologic parameter in bile duct carcinoma(BDC), and evaluate the potential prognostic value. Methods The expression of Cyclin D1, Rb in BDC was detected by immunochemical staining(S-P method). Results Of 42 samples, 22 cases exhibited Cyclin D1 positive expression(52.38%), correlated with histological grade(P=0.044), hepatic invasion(P=0.0046), clinic stage(P=0.0001) and survival time(P=0.0011). The Rb positive rate was 57.14%(24/42), while the expression was related to histologic grade(P=0.0052), clinic stage(P=0.0042), and lymphatic metastasis(P=0.0068). Conclusions Ccylin D1 and Rb are correlated with some clinicopathologic parameter of BDC, and Cyclin D1 is a valuable prognostic marker of BDC.
