    Childhood Brain Stem Glioma Treatment (PDQ®): Treatment - Patient Information [NCI] - Treatment Option Overview

    continued...

    Six types of standard treatment are used:

    Surgery

    Surgery may be used to diagnose and treat childhood brain stem glioma as discussed in the General Information section of this summary.

    Radiation therapy

    Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer. Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer.

    Radiation therapy to the brain can affect growth and development in young children. Conformal radiation therapy is a type of radiation therapy that uses a computer to make a 3-dimensional (3-D) picture of the tumor and shapes the radiation beams to fit the tumor. This allows a high dose of radiation to reach the tumor and causes less damage to normal tissue around the tumor.

    The way the radiation therapy is given depends on the type of the cancer being treated. External radiation therapy is used to treat DIPG. External and/or internal radiation therapy may be used to treat focal or low-grade brain stem gliomas.

    Several months after radiation therapy to the brain, imaging tests may show changes to the brain tissue. These changes may be caused by the radiation therapy or may mean the tumor is growing. It is important to be sure the tumor is growing before any more treatment is given.

    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 reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly in the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type of the cancer being treated.
