Los investigadores de la Universidad de Carolina del Norte en Chapel Hill (Estados Unidos) revisaron los datos de niños diagnosticados con esta patología entre 1992 y 1994 en 139 hospitales estadounidenses y canadienses. Todos los pacientes estaban incluidos en dos grandes ensayos colaborativos del Children´s Oncology Group y el Pediatric Oncology Group. Se recogieron datos de consumo de vitaminas antes y durante el embarazo de 538 casos y 504 controles.
Las mujeres que consumían suplementos vitamínicos y de minerales el mes anterior a quedar embarazadas o en cualquiera de los trimestres posteriores redujeron el riesgo de neuroblastoma entre el 30% y el 40%. Los investigadores no han sido capaces de determinar qué minerales o vitaminas produjeron este efecto, por lo que indican que son necesarios estudios adicionales que evalúen el potencial de vitaminas específicas en la prevención o la modificación del riesgo de neuroblastoma.
