This phase I trial is studying the side effects and best dose of pyrazoloacridine given together with peripheral stem cell or bone marrow transplantation in treating young patients with high-risk neuroblastoma. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell or bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells.
