RATIONALE: Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. Combining chemotherapy with peripheral stem cell transplant may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Combining isotretinoin and monoclonal antibodies may kill any remaining tumor cells following surgery. It is not yet known which treatment regimen is more effective in treating neuroblastoma.
PURPOSE: This randomized phase III trial is studying how well combination chemotherapy with or without filgrastim before surgery, high-dose chemotherapy, and radiation therapy followed by isotretinoin with or without monoclonal antibody work in treating patients with neuroblastoma.
