Newly Diagnosed Childhood Ependymoma
Recurrent Childhood Ependymoma

A link to a list of current clinical trials is included for each treatment section. For some types or stages of cancer, there may not be any trials listed. Check with your doctor for clinical trials that are not listed here but may be right for you.

Newly diagnosed childhood ependymoma is a tumor that has not been treated. The patient may have received drugs or treatment, however, to relieve symptoms caused by the tumor.

Initial treatment for newly diagnosed childhood ependymoma is usually surgery, with or without additional treatment.

After surgery, treatment depends on the age of the child, the amount of tumor that was removed, and whether cancer cells have spread to other parts of the central nervous system.

When the tumor is completely removed by surgery and cancer cells have not spread within the central nervous system, treatment may include the following:

• Radiation therapy to the tumor bed (where the tumor was before it was removed), for children aged 3 years or older.
• A clinical trial of watchful waiting, for children aged 1 year or older.
• A clinical trial of conformal radiation therapy.
• A clinical trial of chemotherapy with or without radiation therapy.

When a part of the tumor remains after surgery, but cancer cells have not spread within the central nervous system, treatment may include the following:

• Second-look surgery.
• Radiation therapy to the tumor bed, for children aged 3 years or older.
• A clinical trial of chemotherapy followed by second-look surgery and conformal radiation therapy, for children aged 1 year or older.

When cancer cells have spread within the central nervous system, treatment may include the following:

• Radiation therapy to the whole brain and spine.
• A clinical trial of radiation therapy and chemotherapy.

Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with newly diagnosed childhood ependymoma ¹.

Standard treatment of recurrent childhood ependymomas may include the following:

• Surgery.
• Radiation therapy, including stereotactic radiation therapy with or without chemotherapy.
• Chemotherapy with or without radiation therapy.

Glossary Terms

A procedure that uses a computer to create a 3-dimensional picture of the tumor. This allows doctors to give the highest possible dose of radiation to the tumor, while sparing the normal tissue as much as possible. Also called 3-dimensional radiation therapy.

A term for diseases in which abnormal cells divide without control. Cancer cells can invade nearby tissues and can spread to other parts of the body through the blood and lymph systems. There are several main types of cancer. Carcinoma is cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord.

The individual unit that makes up the tissues of the body. All living things are made up of one or more cells.

CNS. The brain and spinal cord. Also called CNS.

Treatment with drugs that kill cancer cells.

A type of research study that tests how well new medical approaches work in people. These studies test new methods of screening, prevention, diagnosis, or treatment of a disease. Also called a clinical study.

The process of identifying a disease by the signs and symptoms.

Any substance, other than food, that is used to prevent, diagnose, treat or relieve symptoms of a disease or abnormal condition. Also refers to a substance that alters mood or body function, or that can be habit-forming or addictive, especially a narcotic.

A type of brain tumor that begins in cells lining the spinal cord central canal (fluid-filled space down the center) or the ventricles (fluid-filled spaces of the brain). Ependymomas may also form in the choroid plexus (tissue in the ventricles that makes cerebrospinal fluid). Also called ependymal tumor.

The use of high-energy radiation from x-rays, gamma rays, neutrons, protons, and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external-beam radiation therapy), or it may come from radioactive material placed in the body near cancer cells (internal radiation therapy). Systemic radiation therapy uses a radioactive substance, such as a radiolabeled monoclonal antibody, that travels in the blood to tissues throughout the body. Also called radiotherapy and irradiation.

Cancer that has recurred (come back), usually after a period of time during which the cancer could not be detected. The cancer may come back to the same place as the original (primary) tumor or to another place in the body. Also called recurrence.

Surgery performed after primary treatment to determine whether tumor cells remain.

The extent of a cancer in the body. Staging is usually based on the size of the tumor, whether lymph nodes contain cancer, and whether the cancer has spread from the original site to other parts of the body.

In medicine, treatment that experts agree is appropriate, accepted, and widely used. Health care providers are obligated to provide patients with standard therapy. Also called standard of care or best practice.

A type of external radiation therapy that uses special equipment to position the patient and precisely deliver radiation to a tumor. The total dose of radiation is divided into several smaller doses given over several days. Stereotactic radiation therapy is used to treat brain tumors and other brain disorders. It is also being studied in the treatment of other types of cancer, such as lung cancer. Also called stereotactic external-beam radiation therapy and stereotaxic radiation therapy.

A procedure to remove or repair a part of the body or to find out whether disease is present. An operation.

An indication that a person has a condition or disease. Some examples of symptoms are headache, fever, fatigue, nausea, vomiting, and pain.

An abnormal mass of tissue that results when cells divide more than they should or do not die when they should. Tumors may be benign (not cancerous), or malignant (cancerous). Also called neoplasm.

Closely monitoring a patient's condition but withholding treatment until symptoms appear or change. Also called observation.
