title: Increased incidence of hepatocellular carcinoma (HCC) in HIV-1 infected patients.
abstract: BACKGROUND: The likely increased incidence of hepatocarcinoma (HCC) in HIV-1 infected patients has not yet been demonstrated. METHODS: We studied all cases of HCC occurring in HIV-1 infected patients in our hospital during the past 15 years. Incidence and survival time were compared with those of the general population in the same area and the same time of the study. RESULTS: We found 6 cases of HCC in a cohort of 2383 HIV-1 infected patients between 1986 and 2001. This is a higher than expected incidence rate of HCC compared with the general population, with a standardized incidence ratio of 13.95. Chronic hepatitis virus infection and alcohol abuse were present in four and two cases, respectively. In one patient, no liver disease was known before the HCC and the surrounding liver was normal in the necropsy study. CONCLUSION: The improved survival of patients on highly active antiretroviral treatment (HAART) and the increasing incidence of end-stage liver disease in these patients caused by chronic hepatitis virus infection and alcohol abuse may be responsible for an increase in the incidence of HCC in HIV-1 infected patients.
