[Fundamental and translational research on hepatocellular carcinoma in 2008: forces and priorities].

Hepatocellular carcinogenesis is usually the result of a muti-step process. It begins with an exposure to various risk factors; followed by the development of a chronic hepatitis and cirrhosis that is a pre-neoplastic step; and finally after the occurrence of an hepatocellular carcinoma (HCC), different molecular events control aggressiveness of the tumors. The aim of this work was to identify in the international context, forces and priorities of the fundamental and translational HCC research.
