Abstract
The peak incidence of neuroblastoma during early in-fancy indicates that prenatal factors may play a role in the pathogenesis of this disease. A population-based case-control study was conducted comparing birth certificate data of 157 children who later died from neuroblastoma in Texas with 314 controls randomly selected from all Texas live births. Analysis of birth certificate data revealed a protective relative risk estimate for preterm births (<37-wk gestation), with an overall odds ratio of 0.29 (95% confidence limits of 0.10–0.86). This effect was independent of birth weight and ethnic group. A statistically significant odds ratio of 3.22 was detected for term babies whose birth weight was low. The findings suggest that the fetus is susceptible to an in utero oncogenic initiator or promoter during the last 4 weeks of gestation.
