    Neuroblastoma Treatment (PDQ®): Treatment - Patient Information [NCI] - Treatment Option Overview

    continued...

    Maintenance therapy is given after high-dose chemotherapy and radiation therapy with stem cell rescue to kill any cancer cells that may regrow and cause the disease to come back. Maintenance therapy is given for 6 months and includes the following treatments:

    • Isotretinoin: A vitamin -like drug that slows the cancer's ability to make more cancer cells and changes how these cells look and act. This drug is taken by mouth.
    • Anti-GD2 antibody ch14.18: A type of monoclonal antibody therapy that uses an antibody (ch14.18) made in the laboratory from a single type of immune system cell. ch14.18 identifies and attaches to a substance, called GD2, on the surface of neuroblastoma cells. Once the ch14.18 attaches to the GD2, a signal is sent to the immune system that a foreign substance has been found and needs to be killed. Then the body's immune system kills the neuroblastoma cell. This drug is given by infusion.
    • Granulocyte-macrophage colony-stimulating factor (GM-CSF): A cytokine that helps make more immune system cells, especially granulocytes and macrophages (white blood cells), which can attack and kill cancer cells.
    • Interleukin-2 (IL-2): A type of biologic therapy that boosts the growth and activity of many immune cells, especially lymphocytes (a type of white blood cell). Lymphocytes can attack and kill cancer cells.

    New types of treatment are being tested in clinical trials.

    This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI Web site.

    Targeted therapy

    Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Tyrosine kinase inhibitor (TKI) therapy is one type of targeted therapy being studied in the treatment of neuroblastoma.

    TKI therapy blocks signals needed for tumors to grow. TKIs block the enzyme, tyrosine kinase, that causes stem cells to become more white blood cells (granulocytes or blasts) than the body needs. Crizotinib is one of the TKIs being studied to treat neuroblastoma that has come back after treatment. TKIs may be used in combination with other anticancer drugs as adjuvant therapy (treatment given after the initial treatment, to lower the risk that the cancer will come back).
