Neuroblastoma is the most common extracranial solid cancer in infancy and childhood. It arises from any neural crest element of the sympathetic nervous system. more...
Differentiation
Other tumors also have similar origins and show a wide pattern of differentiation ranging from benign ganglioneuroma to partially differentiated ganglioneuroblastoma to highly malignant neuroblastoma.
Neuroblastoma is one of the rare human malignancies known to demonstrate spontaneous regression from an undifferentiated state to a completely benign cellular appearance.
Treatment
When the lesion is localized, it is generally curable. However, long-term survival for children with advanced disease is poor despite aggressive multimodality therapy.
Recent biologic and genetic characteristics have been identified, which, when added to classic clinical staging, has allowed accurate patient assignment to risk groups so that treatment strategies can be more effectively undertaken.
