Both HBV and HCV are implicated as
causes of intrahepatic cholangiocarcinomas. Hepaitis B surface antigen
(HBsAg) alone fails to identify many cases of HBV infection. Core
antigen (HBcAg) and HBV DNA in tissue samples should also be tested.
And HCV DNA by reverse transcriptase PCR as well as antibodies to HCV.

cholangiocarcinoma and cholangiohepatocarcinoma]. WL Wang. Zhonghua
Zhong Liu Za Zhi 1993 Jul;15(4):252-255. 12 intrahepatic
cholangiocarcinomas, 8 cholangiohepatocarcinomas, and neighboring liver
tissues with chronic hepatitis or cirrhosis surrounding the tumor. By
IHC, "15 were positive for HBxAg (75%), 8 positive for pre-S1 and
pre-S2 (40%), respectively and 2 for HBsAg (10%). Sixteen of 19 liver
tissues surrounding the tumor were also positive for HBxAg (84.2%), 9
for pre-S1 and pre-S2 each (47.4%), 6 for HBsAg and HBcAg each (31.6%)."

primary intrahepatic cholangiocarcinoma and its surrounding tissue]. W
Wang, G Gu, M Hu. Zhonghua Zhong Liu Za Zhi 1996 Mar;18(2):127-130. By
ISH, "33 cases (82.5%) were positive for HBV DNA, while 31 (77.5%), 26
(65.0%), 24 (60.0%) and 27 (67.5%) cases were positive for X gene,
pre-S gene, S gene and C gene, respectively. The results of this study
suggest that there exists a close relationship between human primary
intrahepatic cholangiocarcinoma and HBV chronic persistent infection.
The expression of X gene might play an important role in the
pathogenesis of the primary intrahepatic cholangiocarcinoma."

Risk factors for intrahepatic cholangiocarcinoma: a possible role of
hepatitis B virus. M Tanaka, H Tanaka, H Tsukuma, A Ioka, A Oshima, T

154,814 blood donors in Japan during an average of 7.6 years. "Compared
with those who tested negative for both HBsAg and anti-HCV, those who
tested HBsAg-positive had a significantly higher risk for ICC (HR:
8.56; 95%CI: 1.33-55.20)." "The hazard ratio for anti-HCV positivity
was 2.63, although it was not significant." "The mechanism of
carcinogenesis by HBV in intrahepatic bile ducts has not yet been
elucidated, but HBV infection is an established risk factor for
hepatocellular carcinoma. Because both hepatocytes and cholangiocytes
differentiate from the same progenitor cells, HBV might induce
carcinogenesis in both cell types through the same mechanism. The HBV
gene has been detected in cholangiocarcinoma tissue in some studies,
and its presence has been associated with the potential of
carcinogenesis in human cholangiocytes. Alternatively,
hepatitis-associated ICC may arise from hepatic progenitor cells, as
suggested by Lee et al."
Intrahepatic cholangiocarcinoma: new insights in pathology. C
Sempoux, G Jibara, SC Ward, C Fan, L Qin, S Roayaie, MI Fiel, M
Schwartz, SN Thung. Semin Liver Dis 2011 Feb;31(1):49-60. 73 ICCs from
The Mount Sinai Medical Center in New York City. "Cholangiocarcinomas
are malignant tumors that derive from cholangiocytes of small
intrahepatic bile ducts or bile ductules (intrahepatic
cholangiocarcinoma; ICC), or of large hilar or extrahepatic bile ducts
(extrahepatic cholangiocarcinoma; ECC). ICC and ECC differ in
morphology, pathogenesis, risk factors, treatment, and prognosis...
Classical ICCs (54.8%) were characterized by a tubular, glandular, or
nested pattern of growth, were significantly associated with tumor size
of more than 5 cm and the absence of underlying liver disease and/or
advanced fibrosis. Nonclassical ICCs (45.2%) consisted of tumors with
trabecular architecture, tumors that exhibited features of extrahepatic
carcinomas, and carcinomas considered to be derived from hepatic
progenitor cells, i.e., combined hepatocellular/cholangiocarcinomas and
cholangiolocellular carcinomas (ductular type of ICC). They were
smaller and often arose in chronic liver disease, mostly HCV infection,
and/or with significant fibrosis."
