Radiation therapy uses high-energy beams, such as X-rays, to destroy cancer cells. Children with low-risk or intermediate-risk neuroblastoma may receive radiation therapy if surgery and chemotherapy haven't been helpful. Children with high-risk neuroblastoma may receive radiation therapy after chemotherapy and surgery, to prevent cancer from recurring.
Bone marrow transplant:
Children with high-risk neuroblastoma may receive a transplant using stem cells collected from bone marrow (autologous stem cell transplant). Before the bone marrow transplant, also known as stem cell transplant, your child undergoes a procedure that filters and collects stem cells from his or her blood. The stem cells are stored for later use.
Immunotherapy uses drugs that work by signaling your body's immune system to help fight cancer cells. Children with high-risk neuroblastoma may receive immunotherapy drugs that stimulate the immune system to kill the neuroblastoma cells.
Doctors are studying a newer form of radiation therapy that may help control high-risk neuroblastoma. The treatment uses a radioactive form of the chemical metaiodobenzylguanidine (MIBG). When injected in to the bloodstream, the MIBG travels to the neuroblastoma cells and releases the radiation.
