Abstract
Purpose: To determine the incidence of hepatocellular carcinoma in cirrhosis and to examine the influence of age and sex, and the contribution of etiological factors. Methods: 967 patients with liver cirrhosis and free of hepatocellular carcinoma were enrolled in this longitudinal, retrospective and observational study. Monitoring for hepatocellular carcinoma was scheduled at 3- to 6-month intervals. The mean (±SD) length of follow-up was 60.3 ± 51.7 months (range 6–258). Results: During the observation period, hepatocellular carcinoma developed in 64 patients. The calculated annual incidence was 2.1%. The probability of being free of liver cancer was 92% at 5 years, 80% at 10 years, and 69% at 15 years. Age was the only independent risk factor for the development of malignancy in the multivariate analysis. There were no differences according to male sex, alcohol abuse, and chronic hepatitis B and C virus infection. Conclusions: The annual incidence of hepatocellular carcinoma was 2.1%. These results, although confirming that age is a risk factor for hepatocellular carcinoma in cirrhosis, indicate that alcohol abuse, male sex, and concurrent hepatitis B and C virus infection do not involve a higher risk of developing liver cancer.
