Treatment Option Overview

    continued...

    Radiosurgery and proton beam therapy are two kinds of external radiation therapy used to treat childhood cancers:

    • Radiosurgery uses special equipment to aim one large dose of radiation directly at a tumor, causing less damage to nearby healthy tissue. It is also called stereotaxic radiosurgery, stereotactic radiosurgery, and radiation surgery. This procedure does not remove the tumor in an operation.
    • Proton beam radiation therapy is a type of high-energy radiation therapy that uses streams of protons (small, positively-charged particles of matter) to kill tumor cells.

    Chemotherapy

    Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can affect cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, a body cavity such as the abdomen, or an organ, the drugs mainly affect cancer cells in those areas. Combination chemotherapy is treatment using more than one anticancer drug. The way the chemotherapy is given depends on the type and stage of the cancer being treated.

    Hormone therapy

    Hormone therapy is a cancer treatment that removes hormones or blocks their action and stops cancer cells from growing. Hormones are substances that are made by glands in the body and flow through the bloodstream. Some hormones can cause certain cancers to grow. If tests show that the cancer cells have places where hormones can attach (receptors), drugs, surgery, or radiation therapy is used to reduce the production of hormones or block them from working. Hormone therapy with drugs called corticosteroids may be used to treat thymoma or thymic carcinoma.

    Biologic therapy

    Biologic therapy is a treatment that uses the patient's immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy.

    Interferon-beta is a type of biologic therapy used to treat nasopharyngeal cancer.
