Prenatal and postnatal histories of very low birthweight infants who developed hepatoblastoma*

Abstract

These results suggest the presence of an environmental etiology, rather than a genetic one, which is responsible for the development of hepatoblastoma in children of very low birthweight. Close monitoring of the children after being discharged from the neonatal intensive care unit is essential and a case-control study is necessary to identify risk factors for hepatoblastoma in children of very low birthweight.
