Observational study. All HIV-infected patients who have been diagnosed of hepatocellular carcinoma (HCC), following the American Association for the Study of Liver Diseases (AASLD) criteria, in the participant centers are included. Epidemiological, clinical and laboratory data are collected. The clinical and epidemiological characteristics of HCC cases will be analyzed. The efficacy and outcomes after modalities of HCC therapy will be assessed. Mortality and its predictors will be also assessed. In those cases infected by hepatitis C virus (HCV), the impact of HCV therapy on outcomes will be analysed.
