    Abstract:

    In the United States, hepatocellular carcinoma (HCC) is more common among Asians and African Americans than Caucasians, with chronic hepatitis C virus (HCV) infection accounting for up to half of the patients. Our study examined ethnicity as a potential risk factor for HCC among patients with chronic hepatitis C.We conducted a case-control study of 464 patients with chronic hepatitis C and cirrhosis (207 cancer patients and 257 controls) using medical records and pathology records at 4 medical centers. We estimated odds ratios with 95% confidence intervals by using conditional logistic regression on case-control sets, matched within study centers and study period on sex and age groups (< or =45, 46-55, 56-65, >65 yr). To control for potential confounding caused by severity of cirrhosis and residual confounding caused by age, we also included Child-Turcotte-Pugh (CTP) scores and age (continuous variable) in all regression analyses.Compared with Caucasians, the cancer risk was increased significantly among Asians (adjusted odds ratio, 4.3; 95% confidence interval, 2.1-9.0 for men, and 4.6; 1.2-18.5 for women) and somewhat increased among African-American men (adjusted odds ratio, 2.4; 95% confidence interval, 0.9-6.3).This study suggests that, among patients with chronic hepatitis C and cirrhosis, liver cancer risk is increased 4-fold in Asians and may be doubled in African-American men, compared with Caucasians. These results need confirmation in larger studies from racially diverse populations, but, if confirmed, these results point to high-risk populations that should be targeted for screening and preventive efforts.
