Abstract
PURPOSE: The impact of familial clustering of hepatocellular carcinoma (HCC) in hepatitis B virus (HBV)-infected persons in a low HBV endemic area was investigated. METHODS: Four hundred thirteen HBsAg-positive patients, 173 with HCC and 240 without HCC, were subgrouped into those with or without a family history of HCC and analyzed for risk factors associated with HCC development. In families with HCC clustering, the ages of HCC onset in parents and siblings were compared. RESULTS: Forty-four of 173 (25.4 %) HCC patients, all of Asian descent, had 82 other blood relatives with HCC. Of these, 69 (84.1 %) were first-degree relatives. Compared to HCC patients without HCC family history, male HCC patients with family history developed HCC at a younger age than either their mothers or fathers with HCC (45.2 ± 10.3 years vs. 63.0 ± 6.8 years, p < 0.001 and 41.2 ± 14.8 years vs. 60.5 ± 5.5 years, p = 0.001, respectively); however, this was not observed in female HCC patients. In mothers of index HCC cases, 22/26 (84.6 %) tested were HBsAg positive and 14 (63.6 %) had HCC; in fathers, 11/21 (52.4 %) tested were HBsAg positive and 10 (90.9 %) had HCC. By multivariate analysis, independent risk factors for HCC development included family history (OR = 2.58, p = 0.05), male gender (OR = 3.23, p = 0.03), cirrhosis (OR = 2.4, p = 0.04), Child-Pugh classification (OR = 7.62, p = 0.004), AFP per log10 increase (OR = 1.68, p = 0.01), precore mutation (OR = 3.77, p = 0.003), and basal core promoter mutation (OR = 8.33, p < 0.001). CONCLUSIONS: HBsAg-positive male HCC patients presented at a younger age than their parents with HCC. In adult patients with an HCC family history, HCC surveillance should begin at the time of the initial clinic encounter.
