HOUSTON, Jan. 16 (UPI) -- Infection with hepatitis C increases a person's risk for cancer of the biliary tree, the bile pathway from the liver and pancreas, U.S. researchers said.

To better understand the associations between hepatitis C and cancer, study leader Hashem El-Serag of Baylor College of Medicine conducted a retrospective cohort study of more than 718,000 U.S. veterans who were treated at Veterans Affairs medical facilities from Oct. 1, 1988, to Sept. 30, 2004.

Among the veterans, 146,394 were infected with hepatitis C and 572,293 were not. Uninfected subjects were matched to infected ones by sex, age and type and date of visit.

The researchers tracked the subjects for an average of 2.3 years to determine the incidence these cancers.

The study, published in the Hepatology, found that "risk for biliary tree cancer in the hepatitis C-infected cohort, although low -- 4 per 100,000 person-years -- was more than double that in the hepatitis C-uninfected cohort."
