Abstract:Neuroblastoma is the most common extracranial solid tumor of childhood and is responsible for over 15% of pediatric cancer
deaths. Neuroblastoma tumorigenesis and malignant transformation is driven by overexpression and dominance of cell survival pathways
and a lack of normal cellular senescence or apoptosis. Therefore, manipulation of cell survival pathways may decrease the malignant
potential of these tumors and provide avenues for the development of novel therapeutics. This review focuses on several facets of cell
survival pathways including protein kinases (PI3K, AKT, ALK, and FAK), transcription factors (NF-κB, MYCN and p53), and growth
factors (IGF, EGF, PDGF, and VEGF). Modulation of each of these factors decreases the growth or otherwise hinders the malignant
potential of neuroblastoma, and many therapeutics targeting these pathways are already in the clinical trial phase of development.
Continued research and discovery of effective modulators of these pathways will revolutionize the treatment of neuroblastoma.
