Rios P, et al. - Via this pooled analysis of two French national population-based case–control studies, researchers investigated the influence of parental smoking and alcohol consumption during pregnancy on the risk of neuroblastoma (NB) in children. They interviewed the mothers of 357 NB cases and 1,783 controls from the general population, frequency matched by age and sex, on demographic, socioeconomic and perinatal characteristics, maternal reproductive story, and life-style and childhood environment. Findings suggest no association of maternal alcohol intake during pregnancy but provide some evidence of an association of maternal smoking during pregnancy with NB.
