流行病学研究将癌症风险增加与长期饮酒相关联[例如,Hakulinen等人,1974; Breslow和Enstrom,1974; Feldman等人,1985年;威廉姆斯和霍恩,1977年;肖滕菲尔德,1979年;科诺和池田,1979年;特尼斯,1979年;多尔和佩塔,1981年]。然而,这种关联的实验证据尚不清楚。虽然许多研究表明酒精饮料的活性成分乙醇增加了化学诱导肿瘤的发生率[例如,Gibel,1967; Griciute等人,1982; Gabriel等人,1982;麦考伊等人,1986],其他研究没有显示这种效应[Schmahl等人,1965; Sehmahl,1976; Habs和Sehmahl,1981; Teschke等人,1983年]。我们最近报道的研究表明,只有在用食管特异性致癌物N-亚硝基甲基苄胺(NMBzA)治疗完成后,作为肿瘤促进剂给药时,乙醇才会增加肿瘤发生率[Mufti et al.,1989年]。在这些研究中,我们希望确定乙醇作为肿瘤促进剂对N-亚硝基二乙胺(NDEA)诱导的肝癌发生的影响。该文件提供了一个解释,在这些研究中获得的负面结果。
Epidemiologic studies associate an increased cancer risk with chronic alcohol consumption [for example, Hakulinen et al., 1974; Breslow and Enstrom, 1974; Feldman et al., 1985; Williams and Horn, 1977; Schottenfeld, 1979; Kono and Ikeda, 1979; Tnyns, 1979; Doll and Peta, 1981]. However, the experimental evidence for this association is not clear. While a number of studies indicate that ethanol, the active ingredient of alcoholic beverages, increases the incidence of chemically induced tumors [for example, Gibel, 1967; Griciute et al., 1982; Gabriel et al., 1982; McCoy et al., 1986], other studies do not show such an effect [Schmahl et al., 1965; Sehmahl, 1976; Habs and Sehmahl, 1981; Teschke et al., 1983]. We recently reported studies that showed that ethanol increased tumor incidence only when administered as a tumor promoter after treatment with an esophagus specific carcinogen, N-nitrosomethylbenzlamine (NMBzA) was completed [Mufti et al., 1989]. In these studies we wanted to determine the effect of ethanol when given as a tumor promoter on liver carcinogenesis induced by N-nitrosodiethylamine (NDEA). The paper offers an explanation for the negative results obtained in these studies.
