Current Clinical Trials in Neuroblastoma

Neuroblastoma is a pediatric malignant tumor of the postganglionic sympathetic nervous system that usually develops in the adrenal gland or in nonadrenal abdominal or thoracic sites.[1] It is the most common malignancy in infants and the most common extracranial solid tumor of childhood, with approximately 650 cases diagnosed annually in the United States.[2] The dramatic age-related survival differences among neuroblastoma patients with a similar tumor stage emphasize the heterogeneity of neuroblastoma pathobiology. Early research efforts to understand the pathobiology of neuroblastoma[3-5] and the significant progress made in neuroblastoma molecular biology[6] have informed the clinical treatment of neuroblastoma.
