Monoclonal Antibody Therapy With Sargramostim and Interleukin-2 in Treating Children With Neuroblastoma

Monoclonal antibodies 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. Interleukin-2 may stimulate a person's white blood cells to kill cancer cells. Combining monoclonal antibody therapy with sargramostim or interleukin-2 may kill more tumor cells. Phase I trial to study the effectiveness of monoclonal antibody therapy given with sargramostim and interleukin-2 in treating children with neuroblastoma who have just completed bone marrow or peripheral stem cell transplantation
