[A study on the multiple factorial causation of hepatoma among young patients].

Pathogenetic significance of major risk factors to primary hepatoma among young people was investigated through a case-control study. The analysis of single-factor showed that there was close relationship between HBV infection, family history of hepatoma and the primary hepatocellular carcinoma among young people, with an OR 25.3. Multiple-factorial analysis indicated that the effect of HBV infection far exceeded other risk factors in the pathogenesis of primary hepatoma, suggesting the HBV infection might be a major cause of primary hepatoma among young people.
