This trial is looking at proton beam radiation therapy (PBRT) as a possible treatment for neuroblastoma. Neuroblastoma is a cancer that most commonly occurs in and around the adrenal glands, but can also occur in other areas where groups of nerve cells exist. Standard radiation therapy with photons is used as standard treatment for many patients with neuroblastic tumors, but proton radiation is known to spare surrounding tissues and organs from unnecessary radiation. The trial will assess the effectiveness of PBRT in reducing side effects associated with radiation treatment and the late side effects experienced by participants.
