Impact of interferon-alpha therapy on the development of hepatocellular carcinoma in patients with liver cirrhosis: results of an international survey
Abstract
Clinico-epidemiological data show that the most severe forms of hepatitis C virus (HCV) associated liver disease occur in patients with multifactorial liver damage. We found that the prevalence of hepatitis B virus (HBV) markers in anti-HCV positive patients with cirrhosis complicated by hepatocellular carcinoma (HCC) is higher than in cirrhotics with comparable age and disease history, but without HCC. HBV can persist in integrated forms in HBsAg negative, anti-HBc positive individuals and we may speculate that in such patients concurrent liver pathogens, as HCV, could cause HCC more easily than in patients without previous exposure to HBV. Analysing the relations between age at HCC diagnosis and the different risk factors in consecutive HCC patients we found that patients with single hepatitis virus infections (HBsAg and/or anti-HCV positive) were of an older median age than patients with multiple hepatitis virus infections. We also studied patients with compensated cirrhosis and hepatitis virus infections. untreated or treated with interferon-alpha. The independent effect of treatment was analysed by matching groups with regard to all the other significant HCC risk factors. The overall relative HCC risk was three times highe...Continue Reading
