We confirmed the strong association of hepatoblastoma with very low birth weight (relative risk <1000 g vs ≥2000 g=25.6; 95% confidence interval: 7.70-85.0) and demonstrated independent associations with congenital abnormalities and maternal Asian race in a population-based Minnesota study that included 36 cases and 7788 controls.
