title: Hepatocellular carcinoma not related to hepatitis B virus infection among Alaska natives.
abstract: Chronic infection with hepatitis B or C viruses is a common underlying condition in patients with hepatocellular carcinoma worldwide. We studied serum and liver tissue from a cohort of Alaska natives with hepatocellular carcinoma (HCC) for evidence of hepatitis B, C and G viral infection using conventional serological tests as well as the sensitive polymerase chain reaction. Evidence of HBV infection was found in 25 and possible HCV infection in two cases. Among the remaining 11 patients, four had a history of recent or remote alcoholism while seven had no recognizable risk factors for HCC. Only one was seropositive for HGV RNA and that was an individual with a history of alcoholism. Non-tumorous liver tissue was available for study in six of these seven cases. Histological features of chronic hepatitis were present in five. Thus, at least five of 38 (13%) Alaska natives with HCC appeared to have chronic hepatitis not related to HBV or HCV infection, suggesting the possibility of some form of previously unrecognized chronic liver disease predisposing to HCC.
