Neuroblastoma (cont.)
Treatment of neuroblastoma is based on risk groups.
For many types of cancer, stages are used to plan treatment. For
neuroblastoma, treatment depends on risk groups. The stage of neuroblastoma is
one factor used to determine risk group. Other factors are the age of the child,
tumor histology, and tumor biology.
There are 3 risk groups: low risk, intermediate risk, and high risk.
- Low-risk and intermediate-risk neuroblastoma have a good chance of being
cured.
- High-risk neuroblastoma may be difficult to cure.
Progressive/recurrent neuroblastoma
Progressive neuroblastoma is cancer that has progressed (continued to grow)
during treatment. Recurrent neuroblastoma is cancer that has recurred (come
back) after it has been treated. The cancer may come back in the same place or
in other parts of the body.
Treatment option overview
There are different types of treatment for patients with neuroblastoma.
Different types of treatment are available for patients with neuroblastoma.
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 Web site 2.
Choosing the most appropriate cancer treatment is a decision that ideally
involves the patient, family, and health care team.
Children with neuroblastoma should have their treatment planned by a team of
doctors with expertise in treating childhood cancer.
Your child's treatment will be managed 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 neuroblastoma and who specialize in certain areas of
medicine. These may include the following specialists:
- Medical oncologist.
- Hematologist.
- Pediatric surgeon.
- Radiation oncologist.
- Endocrinologist.
- Neurologist.
- Neuropathologist.
- Neuroradiologist.
- Pediatric nurse specialist.
- Social worker.
- Rehabilitation specialist.
- Psychologist.
Children who are treated for neuroblastoma may be at higher risk for second
cancers.
Some cancer treatments cause side effects that continue or appear years after
cancer treatment has ended. These are called late effects. Late effects of
cancer treatment include physical problems; changes in mood, feelings, actions,
thinking, learning, or memory; and second cancers.
Some late effects may be treated or controlled. It is important that parents
of children who are treated for neuroblastoma talk with their doctors about the
possible late effects caused by some treatments.
Four types of standard treatment are used:
Surgery
Surgery is usually used to treat neuroblastoma. Depending on where the tumor
is and whether it has spread, as much of the tumor as possible will be removed.
If the tumor cannot be removed, a biopsy may be done instead.
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). The way the chemotherapy is given
depends on the type and stage of the cancer being treated.
The use of two or more anticancer drugs is called combination chemotherapy.
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. These include the
following:
Monoclonal antibody therapy
Monoclonal antibody therapy is a cancer treatment that uses antibodies made
in the laboratory, from a single type of immune system cell. These antibodies
can identify substances on cancer cells or normal substances that may help
cancer cells grow. The antibodies attach to the substances and kill the cancer
cells, block their growth, or keep them from spreading. Monoclonal antibodies
are given by infusion. They may be used alone or to deliver drugs, toxins, or
radioactive material directly to cancer cells.
High-dose chemotherapy and radiation therapy with stem cell transplant
High-dose chemotherapy and radiation therapy with stem cell transplant is a
way of giving high doses of chemotherapy and radiation therapy and replacing
blood -forming cells destroyed by the cancer treatment. Stem cells (immature
blood cells) are removed from the blood or bone marrow of the patient or a donor
and are frozen and stored. After chemotherapy and radiation therapy are
completed, the stored stem cells are thawed and given back to the patient
through an infusion. These reinfused stem cells grow into (and restore) the
body's blood cells.
Other drug therapy
13-cis retinoic acid is a vitamin -like drug that slows the cancer's ability
to make more cancer cells and changes how these cells look and act.

trials, but it may not mention every new treatment being studied. Information
