ABSTRACT
Objective To investigate the expression of Bmi-1,Mdm2 and Ki-67 in extrahepatic biliary duct carcinoma and to evaluate their clinical significance. Methods The expression of Bmi-1.Mdm2 and Ki-67 was detected in 10 normal extrahepatic biliary duct tissue and 30 cases of extrahepatic billary duct carcinoma with immunohistochemic0al staining and the their clinical significance were analyzed. Results No POsitlVe Bmi-1 expression was found in 10 normal extrahepatie biliary duct cages, while 18 of 30 extrahepatic biliary duct carcinoma cases showed positive Bim-1 expression.The expression of Bmi-I in extrahepatic biliary duct carcinoma(60.0%)was statistically higher than that in normal extrahepatie biliary duct(P<0.05).The positive expression rate of Mdm2 in extrahepatic biliary duct carcinoma was significantly higher than that in normal extrahepatic biliary duct (56.7%vs 20.0%,P<0.05).The cases of extrahepatic biliary duct carcinoma with Ki-67 proliferation index higher than 5%reached 60.0%,while the Ki-67 index was all lower than 1%in 10 normal extrahepatic biliary duct tissue, suggesting the higher proliferating activity of extrahepatic biliary duct carcinoma.No differences were found in the expressions of Bmi-1,Mdm2 and Ki-67 among extrahepatic biliary duct carcinoma cases with different clinical pathological features. Conclusion The results indicate that the expression of Bmi-1 and Mdm2 up-regulation may play an important role in carcinogenesis of extrahepatic biliary duct caroinoma. No clinical significances of the expressions of Bmi-1,Mdm2 and Ki-67 are found in extrahepatic biliary duct carcinomas.
