Few studies have examined the role of alcohol consumption in risk of adult acute myeloid leukemia (AML). Two previous case-control studies resulted in inconsistent findings. We report data from a Los Angeles County population-based case-control study in which 164 matched case-control pairs were asked about lifetime history of alcohol consumption and 136 cases were subtyped according to the French-American-British (FAB) criteria. Estimated categorical odds ratios (OR) adjusted for smoking and education were suggestive of a possible protective effect but trend tests were non-significant. Analyses by FAB subtype did not reveal subtype-specific associations but generally suffered from lack of power. Larger studies are needed to more thoroughly investigate the relationship between alcohol consumption and AML risk.
