title: Hepatoblastoma incidence in the United States from 1973 to 1992.
abstract: BACKGROUND
  There is recent evidence to suggest that extremely low birth weight is associated with the occurrence of hepatoblastoma.
  
  
  METHODS
  In light of this possibility, we evaluated trends in hepatoblastoma incidence in the United States among children age 4 years and younger.
  
  
  RESULTS
  We found an increasing trend (5.2%) in hepatoblastoma incidence over the past two decades, a period that corresponds with improved survival of very low birth weight children.
  
  
  CONCLUSIONS
  Future studies of hepatoblastoma that incorporate birth weight are appropriate.
