Failure to detect dopaminergic neuroblastoma in a mass-screening system

Dopaminergic neuroblastoma comprised 12% of the patients under 1 year of age, and 83% of the older ones. Seven cases were missed by the mass-screening system performed at age 6 months and were detected after 16 months. Three of these advanced cases were positive only for dopamine. These findings supports our second mass-screening system using dopamine evaluation at age 14 months.
