Childhood Cerebellar Astrocytoma: Treatment Options

by National Cancer Institute

(Page 2 of 2)

There are different types of treatment for children with cerebellar astrocytoma.

Different types of treatment are available for children with cerebellar astrocytoma. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the "standard" treatment, the new treatment may become the standard treatment.

Because cancer in children is rare, taking part in a clinical trial should be considered. Clinical trials are taking place in many parts of the country. Information about ongoing clinical trials is available from the NCI Cancer.gov Web site. Choosing the most appropriate cancer treatment is a decision that ideally involves the patient, family, and health care team.

Children with cerebellar astrocytoma should have their treatment planned by a team of doctors with expertise in treating childhood brain tumors.

Your child's treatment will be overseen by a pediatric oncologist, a doctor who specializes in treating children with cancer. The pediatric oncologist may refer you to other pediatric doctors who have experience and expertise in treating children with brain tumors and who specialize in certain areas of medicine. These may include the following specialists:

• Neurosurgeon.
• Neurologist.
• Neuropathologist.
• Neuroradiologist.
• Rehabilitation specialist.
• Radiation oncologist.
• Medical oncologist.
• Endocrinologist.
• Psychologist.

Three types of standard treatment are used:

Surgery

Surgery is used to diagnose and treat childhood cerebellar astrocytoma as discussed in the General Information 3 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. 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. The way the radiation therapy is given depends on the type and stage of the cancer being treated.

Chemotherapy

Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells 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 spinal column, a body cavity such as the abdomen, or an organ, the drugs mainly affect cancer cells in those areas. The way the chemotherapy is given depends on the type and stage of the cancer being treated.

Other types of treatment are being tested in clinical trials.

Information about ongoing clinical trials is available from the NCI Cancer.gov Web site.

Treatment Options for Childhood Cerebellar Astrocytoma

Untreated Childhood Cerebellar Astrocytoma

Untreated childhood cerebellar astrocytoma is a tumor for which no treatment has been given. The child may have received drugs or treatment to relieve symptoms caused by the tumor.

Initial treatment for childhood cerebellar astrocytoma is usually surgery. When the tumor is completely removed by surgery, more treatment may not be needed and the child is closely observed for symptoms to appear or change. This is also called watchful waiting.

If cancer cells remain after surgery, treatment depends on the location of the remaining cancer cells and the age of the child. Standard treatment may include the following:

• Watchful waiting.
• Another surgery to remove the tumor.
• Radiation therapy.
• Chemotherapy.

Recurrent Childhood Cerebellar Astrocytoma

Standard treatment of recurrent childhood cerebellar astrocytoma may include the following:

• Surgery.
• Radiation therapy.
• Chemotherapy.
