Outcome of hepatocellular carcinoma in human immunodeficiency virus-infected patients

Background: Although the number of human immunodeficiency virus-infected patients with chronic liver disease is increasing, the impact of human immunodeficiency virus on hepatocellular carcinoma outcome remains unclear. Aims: This single centre study investigated whether human immunodeficiency virus infection per se affects the hepatocellular carcinoma prognosis. Methods: Forty-eight human immunodeficiency virus-infected and 234 uninfected patients consecutively diagnosed with hepatitis virus-related hepatocellular carcinoma from January 2000 to December 2009 were retrospectively enrolled. Hepatocellular carcinoma was staged according to Cancer of the Liver Italian Program criteria. Survival and independent prognostic predictors were evaluated. Survivals were also compared after adjustment and matching by propensity score. Results: Compared to human immunodeficiency virus-uninfected subjects, infected patients were more likely to be males, were younger, had fewer comorbidities and the tumour was more often detected during surveillance. Liver function, tumour characteristics and treatments did not significantly differ between the two groups. Nevertheless, median survival of human immunodeficiency virus-infected patients was approximately half that of their counterpart (16 months [95% confidence interval: 7-25] vs. 30 months [95% confidence interval: 25-35]; p = 0.0354). Human immunodeficiency virus infection, Cancer of the Liver Italian Program score and hepatocellular carcinoma treatment were independently associated with mortality. Notably, human immunodeficiency virus infection doubled the risk of dying. These results were confirmed by propensity analysis. Conclusion: Human immunodeficiency virus infection per se worsens the prognosis of patients with virus-related hepatocellular carcinoma. (c) 2012 Editrice Gastroenterologica Italiana S.r.l.
