Neuroblastoma, an aggressive malignancy originating from neural crest cells, accounts for 15% of cancer-related deaths in children. Treatment strategies include systemic chemotherapy, radiation or immunotherapy with anti-GD2 antibodies, all with severe side effects and long-term toxicity. Retinoic acid (RA) has been shown to promote neuroblastoma growth inhibition while suppressing MYCN oncogene expression. However, its effect is reversible, and tumor regrowth may occur.
