There are different types of treatment for children with brain
stem glioma.
Different types of treatment are available for children with brain stem glioma. 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. Some clinical trials are open only to patients who have not started treatment.
Children with brain stem glioma should have their treatment
planned by a team of health care providers who are experts in treating childhood brain
tumors.
Treatment will be overseen by a pediatric oncologist, a doctor who specializes
in treating children with cancer. The pediatric oncologist works with
other pediatric health care providers who are experts in treating children
with brain tumors and who specialize
in certain areas of medicine. These may include the following specialists:
Childhood brain and spinal cord tumors may cause symptoms that begin before diagnosis and continue for months or years.
Childhood brain and spinal cord tumors may cause symptoms that continue for months or years. Symptoms caused by the tumor may begin before diagnosis. Symptoms caused by treatment may begin during or right after treatment.
Some cancer treatments cause side effects months or years after treatment has ended.
These are called late effects. Late effects may include the following:
- Physical problems.
- Changes in mood, feelings, thinking, learning, or memory.
- Second cancers (new types of cancer).
Some late effects may be treated or controlled. It is important to talk with your child's doctors about the effects cancer treatment can have on your child. (See the PDQ summary on Late Effects of Treatment for Childhood Cancer for more information).
Five types of standard treatment are used:
Surgery
Surgery is 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. Certain ways of giving radiation therapy can help keep radiation from damaging healthy tissue:
The way the radiation therapy is given depends on the type and stage of the cancer being treated.
Radiation therapy may be used alone or in addition to chemotherapy.
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 spinal column, 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 and stage of the cancer being treated.
Because radiation therapy to the brain can affect growth and brain development
in young children, clinical trials are studying ways of using chemotherapy to
delay or reduce the need for radiation therapy.
Cerebrospinal fluid diversion
Cerebrospinal fluid diversion is a method used to drain fluid that has built up around the brain and spinal cord. A shunt (long, thin tube) is placed in a ventricle (fluid-filled space) of the brain and threaded under the skin to another part of the body, usually the abdomen. The shunt carries excess fluid away from the brain so it may be absorbed elsewhere in the body.
Watchful waiting
Watchful waiting is closely monitoring a patient’s condition without giving any treatment until symptoms appear or change.
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.
Radiation therapy with radiosensitizers
Radiosensitizers are
drugs that make tumor cells more sensitive to radiation therapy. Combining radiation therapy
with radiosensitizers may kill more tumor cells.
Patients may want to think about taking part in a clinical trial.
For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.
Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.
Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.
Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's clinical trials database.
Follow-up tests may be needed.
Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. This is sometimes called re-staging.
Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.
