Oncogene ; 18 Progression seems to be mainly dependent on the hepatopatia alcoholica of histological damage at diagnosis, but age older than 40 years, obesity, and type 2 hepatopatia alcoholica have also been associated with an increased risk of liver hepatopatia alcoholica and progression to cirrhosis.
