  1. HCV infection and liver cancer mortality in a Japanese population with HTLV-I.

    Article - En anglais

    In a cohort study of human T-lymphotropic virus type I (HTLV-I) infection in Japan, 10 cases of liver cancer death occurred from 1984 through 1993.

    To analyze the role of hepatitis C virus (HCV), which has been associated with an increasing incidence of hepatocellular carcinoma (HCC) in Japan, a nested case-control study was performed.

    Five of the 10 liver cancer cases were positive for antibody to HTLV-I (anti-HTLV-1).

    The possible interaction between HCV and HTLV-I infections in the etiology of HCC was investigated, with each liver cancer case matched to 5 cohort controls by gender, age, serum sample date and anti-HTLV-1 status.

    Using a matched analysis, odds ratios (OR) were generated for the relationship between HCV serologic status and death from liver cancer.

    Based on second-generation enzyme immunoassay with confirmation by recombinant immunoblot assay, 8 of 9 cases with adequate serum available (89%) and 9 of 50 (18%) controls were found to be positive for antibody to HCV (anti-HCV).

    Liver cancer death was highly associated with anti-HCV (matched OR=p<0.001).

    Anti-HTLV-I seroprevalence was somewhat correlated with HCV infection.

    However, the high risk of liver cancer death observed for anti-HCV-positive individuals in this population did not vary with respect to whether or not the subjects were also infected with HTLV-1.
