 | | Neuroblastoma is a tumor that may arise at any site in the sympathetic nervous system, including the brain, neck (3%), chest next to the spine (20%), abdomen on either side of the aorta (24%), pelvis (3%), and adrenal gland (50%) (Figure 1). |
 | | Neuroblastoma cells secrete many products, including hormones (e.g., vasoactive substances (substances that affect the blood vessels), including catecholamines (the “fight or flight” hormones that raise our heart rate and blood pressure when we are scared) and their byproducts (homovanillic acid [HVA], vanillylmandelic acid [VMA], 3-methoxytyramine, metanephrines, and dopamine). |
 | | During removal of neuroblastomas in the chest, it is often impossible to avoid leaving small amounts of tumor along the nerves as they emerge from the spine. |
