OUTLINE: Patients are stratified by prior therapy (yes vs no). Patients undergo surgery either at diagnosis or after at least 4 courses of chemotherapy, then possibly again after completion of chemotherapy. Patients receive cyclophosphamide IV over 6 hours on days 1-2, and doxorubicin IV and vincristine IV over 72 hours on days 1-3 for courses 1, 2, 4, and 6. Cisplatin IV over 1 hour on days 1-4 and vincristine IV over 2 hours on days 1-3 are administered as courses 3, 5, and 7. Courses are administered every 16-21 days. Autologous bone marrow is collected after 3 courses of chemotherapy providing marrow is negative for tumor cells. Patients undergo radiotherapy after the completion of chemotherapy. Radiotherapy is administered twice a day for 7 days. Patients then receive iodine I 131 labeled monoclonal antibody 3F8 (MOAB 3F8) on day -5 and again on days 1-5. Autologous bone marrow is reinfused on day 5 and filgrastim (G-CSF) is administered IV or subcutaneously beginning day 6. Patients who do not develop HAMA or an allergy to mouse proteins receive unlabeled MOAB 3F8 IV over 1.5 hours, 5 days a week for 2 weeks. Treatment repeats every 1-2 months for up to 4 courses. Patients are followed every month for 2 years, every 3 months for 1 year, then annually thereafter.
