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. Some clinical trials are open only to patients who have not started treatment.
Children with cerebellar astrocytoma 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 of cancer treatment 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).
Three types of standard treatment are used:
Surgery
Surgery is used to diagnose and treat childhood cerebellar astrocytoma 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.
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 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 into the spinal column, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). Combination chemotherapy is the use of more than one anticancer drug. The way the chemotherapy is given depends on the type and stage of the cancer being treated.
New types of treatment are being tested in clinical trials.
Information about clinical trials is available from the
NCI Web site.
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.
