Recent reports indicate that hepatitis C virus (HCV) may play a role in the pathogenesis of hepatocellular carcinoma in cirrhotics. Using an ELISA test, we evaluated the prevalence of anti-HCV antibodies in 97 patients with hepatocellular carcinoma (HCC) in cirrhosis and in a group of 223 patients, including: 49 patients with HBsAg-positive chronic liver disease (CLD), 42 with alcoholic CLD, 110 with cryptogenic CLD and 22 with post-transfusional HBsAg-negative CLD. All diagnoses were histologically confirmed. Overall, anti-HCV-positive HCC were 64% of the total, with no statistically significant difference with respect to CLD (60.9%). The prevalence of anti-HCV was higher in cryptogenic HCC (80%) than in HBsAg-positive (60%) or alcoholic HCC (42.8%) (p less than 0.005). When HCC and cirrhosis of similar putative etiology were considered, anti-HCV prevalence was significantly higher in HCC than in cirrhosis only in the groups of patients with alcoholic liver damage (60% in HCC vs. 38% in cirrhosis, p less than 0.005). In HBsAg-positive patients, anti-HCV prevalence was twice as high in HCC than in CLD, but the difference was not statistically significant. Overall, anti-HCV prevalence in HCC was significantly higher than in alcoholic or HBsAg-positive CLD (p less than 0.001 and p less than 0.01, respectively) but lower than in cryptogenic CLD (p less than 0.001). Association between anti-HCV and anti-HBc was significantly more prevalent in patients with CLD than in those with HCC.(ABSTRACT TRUNCATED AT 250 WORDS)
