A Retrospective Study of the Natural Course of Hepatocellular Carcinoma Related to Hepatitis B Virus and Hepatitis C Virus / 日本農村医学会雑誌

ABSTRACT

The natural course of hepatocellular carcinoma (HCC) was investigated retrospectively in the cases especially related to hepatitis B virus (HBV) and hepatitis C virus (HCV). The average diagnostic age of the patients was significantly higher in HCV-related HCC cases than those associated with HBV, and females were older than men as a general trend regardless of viral type. In the progressive duration of such chronic liver diseases as chronic hepatitis, liver cirrhosis and HCC, there was no significant difference between HCC caused by HBV and HCV-related HCC, but the progress tended to be slower in female cases than in male ones. In the same drinking habit, each progressive duration indicated no remarkable difference between cases related to HBV and HCV, and insignificant difference was also found between those who ingest more than 86 g per day in terms of ethanol comsumption and none or under 86 g per day, regardless of viral type.
