看來越王兄也是一位醫林中人。提的問題，據我所知，還不清楚。Pubmed有幾篇綜述，或可一看。

我有空也會去細看一下。下麵是一醫學網站裏的一句話：The way in which hepatitis C virus causes liver cancer is not well understood. It is known, however, that cirrhosis from any cause is a risk factor for the development of liver cancer. It has been argued, therefore, that hepatitis C virus, which causes cirrhosis of the liver, is an indirect cause of liver cancer.

問好！
