ABSTRACT
Objective To assess hepatitis B virus(HBV)and hepatitis C virus(HCV)infections in different anatomic location of cholangiocarcinoma(CC)and relationship with abnormal p53 expression.Methods A total of 411 CC samples including intrahepatic cholangiocarcinoma(ICC 312 cases);perihilar cholangiocarcinoma(PHC,73 cases)and distal cholangiocarcinoma(DC,26 cases)underwent serologic test for HBsAg and anti-HCV using microparticle enzyme immunoassay.Abnormal p53 expression was detected in formalin-fixed.paraffin-embedded CC tissues by immunohistochemistry.Results Seropositivity for HBsAg and anti-HCV were found in 48.4%(151/312)and 2.9%(9/312)of ICC cases,and in 10.9%(8/73)and zero of PHC,and in 7.7%(2/26)and zero of DC,respectively.Abnormal p53 expression was detected in 30.1%(94/312)of ICC cases.23.3%(17/73)of PHC cases and 19.2%(5/26)of DC cases.There was no correlation between seropositivity of HBsAg and anti-HCV and p53 overexpression among three groups of CC. Conclusions HBV but not HCV infection may be associated with the development of ICC.p53 abnormality may not play a significant role in HBV-associated carcinogenesis of ICC.
