What we are studying
The main purpose of this research study is to find out if using 2 cycles of high dose Consolidation chemotherapy, instead of 1 cycle, will decrease the chance that the neuroblastoma will grow back after therapy. This research study will also find out if adding a new anti-cancer drug to Induction therapy will decrease the number of patients who have tumor present at the end of the Induction phase of therapy. This research study will also find out if patients whose tumor does not go away with initial therapy will need a higher dose of radiation therapy.
