Purpose

This partially randomized phase III trial studies isotretinoin with dinutuximab, aldesleukin, and sargramostim to see how well it works compared to isotretinoin alone following stem cell transplant in treating patients with neuroblastoma. Drugs used in chemotherapy, such as isotretinoin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as dinutuximab, may block tumor growth in different ways by targeting certain cells. Aldesleukin and sargramostim may stimulate a person's white blood cells to kill cancer cells. It is not yet known if chemotherapy is more effective with or without dinutuximab, aldesleukin, and sargramostim following stem cell transplant in treating neuroblastoma.
