Results. Twenty and five-tenths percent of patients
were hepatitis B surface antigen (HBsAg) positive and
68.9% were positive for HCV antibodies. Previous alcohol
abuse was present in Z6.Z%. During follow-up (46.3 k 21.4
months), HCC developed in 32 patients (11.0%) (annual
incidence approximately 3%) including 19.6% of HBsAgpositive
patients, 12.2% of HCV antibody positive patients
and 14.4% of patients with a history of alcohol
abuse. The highest rate of HCC was in patients with dual
HBsAg and anti-HCV positivity with or without previous
alcohol abuse, whereas the lowest incidence (0%) was in
cases without risk factors. By univariate analysis, age
abuse was present in Z6.Z%. During follow-up (46.3 k 21.4
months), HCC developed in 32 patients (11.0%) (annual
incidence approximately 3%) including 19.6% of HBsAgpositive
