title: A case-control study on male hepatocellular carcinoma based on hospital and community controls.
abstract: A case control study on male primary hepatocellular carcinoma(HCC) and hepatitis B or C virus and some potential risk factors, e.g. blood transfusion, aldehyde dehydrogenase 2(ALDH2) genotype and drinking habits, was performed using two controls, i.e. a hospital control(HC) and a community control(CC) in Fukuoka and Saga Prefectures. Cases were obtained from the Second Department of Internal Medicine, Kurume University Hospital. The HCs were obtained from inpatients of two general hospitals in Kurume and the CCs were randomly sampled from the Kurume citizens being matched with age and sex to each case. Based on the HCs, odds ratios(ORs) of developing male HCC were statistically significant due to HBsAg or anti-HCV antibody positive status. Some discrepancies were observed between the two controls, i.e. higher proportions of past histories of diabetes or hypertension, of ALDH2 typical homozygote(ALDH2(1)/ALDH2(1)), and of heavy drinkers among the HCs, suggesting slight deviation of the HCs from the CCs in alcohol related aspects. Although ORs regarding accumulated amount of alcohol intake by age 40 based on the HCs were insignificant, two of the three corresponding ORs based on the CCs were statistically significant. Judging from alcohol related aspects between the two controls, the ORs for alcohol based on the HCs seems to be underestimated.
