Monoclonal Antibody 3F8 and Sargramostim in Treating Patients With Neuroblastoma

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.
