RATIONALE: Monoclonal antibodies, such as monoclonal antibody 3F8, can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Colony-stimulating factors, such as sargramostim, may increase the number of immune cells found in bone marrow or peripheral blood. Combining monoclonal antibody 3F8 with sargramostim may cause a stronger immune response and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combining monoclonal antibody 3F8 with sargramostim in treating patients who have neuroblastoma.

Study summary:

OBJECTIVES: - Determine the efficacy of sargramostim (GM-CSF) in enhancing monoclonal antibody 3F8-mediated ablation in patients with high-risk neuroblastoma. - Determine the prognostic impact of minimal residual bone marrow disease on relapse-free survival of patients treated with this regimen. - Compare the effects of short-term (2-hour intravenous) vs prolonged (subcutaneous release) daily GM-CSF on granulocyte activation, in order to establish the optimal route for tumor-cell kill in these patients. OUTLINE: This is an open-label study. Patients are stratified according to evaluable disease (yes [primary refractory bone marrow disease] vs no [no evidence of disease]). Patients receive sargramostim (GM-CSF) subcutaneously on days -5 to 4 and monoclonal antibody 3F8 IV over 0.5-1.5 hours on days 0-4. Treatment repeats every 3 weeks for 4 courses and then every 8 weeks for up to a total of 24 months in the absence of disease progression or unacceptable toxicity. Beginning after 2 courses of GM-CSF and monoclonal antibody 3F8, patients also receive oral isotretinoin twice daily on days 1-14 (when no monoclonal antibody 3F8 is administered). Treatment with isotretinoin repeats approximately every 28 days for 6 courses. PROJECTED ACCRUAL: A total of 340 patients will be accrued for this study.
