    Abstract:
    PURPOSE: We investigated the clinical and virologic findings in hepatitis B surface antigen (HBsAg)-negative and anti-hepatitis C virus antibody (anti-HCV)-negative patients with hepatocellular carcinoma (HCC) to investigate the role of previous or occult hepatitis B virus (HBV) infections in the development of HCC. METHODS: We examined sera and HCC samples from 40 HBsAg-negative and anti-HCV-negative patients. Sera were tested for some viral markers, and genomic DNA was extracted from the HCC samples. HBx RNA was also extracted from the HCC and amplified by a polymerase chain reaction with reverse transcription (RT-PCR). RESULTS: Hepatocellular carcinomas from five patients with anti-HBc (group 1, 25 patients) and nine patients without anti-HBc (group 2, 15 patients) were examined for HBx RNA. HBx RNA was detected in four of the five HCC samples from group 1 and in four of the nine HCC samples from group 2. CONCLUSION: These findings suggested that previous or occult hepatitis B virus infection is common in HBsAg-negative and anti-HCV-negative patients with HCC.
