Lee YH et al. – Alcoholism in patients with hepatitis B virus (HBV) or hepatitis C virus (HCV) infection is characterized by early development of hepatocellular carcinoma (HCC) with advanced cirrhosis and cancer staging at diagnosis. Alcoholism independently predicts an increased risk of mortality in patients with HBV– and HCV–related HCC.Methods
- A total of 1,888 patients were retrospectively investigated and categorized into six groups, HBV only (n=977), HBV with alcoholism (n=197), HCV only (n=544), HCV with alcoholism (n=67), dual HBV and HCV (n=82), and dual virus with alcoholism (n=21), to examine their interactions on the outcome.
- Compared to their counterparts, alcoholic patients coinfected with HBV and/or HCV tended to be younger, had higher male–to–female ratios, worse performance status, more severe liver cirrhosis, advanced cancer staging, and tumor burden than patients without alcoholism.
- In survival analysis, patients with HBV with alcoholism had a significantly decreased survival than the HBV–only group (p=0.001).
- A shortened survival was also observed in HCV with alcoholism group compared to the HCV–only group (p=0.011).
- Dual virus infection with alcoholism did not significantly worsen the survival compared to the dual virus infection group.
- In the Cox proportional hazards model, HBV with alcoholism group [risk ratio (RR) 1.299, p=0.032] and HCV with alcoholism (RR 1.523, p=0.025) group were independent predictors associated with decreased survival compared to their counterpart of HBV– and HCV–only groups.
