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. Some clinical trials are open only to patients who have not started treatment.
Children with neuroblastoma should have their treatment planned by a team of doctors with expertise in treating childhood cancer, especially neuroblastoma.
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 neuroblastoma and who specialize in certain areas of medicine. These may include the following specialists:
Children who are treated for neuroblastoma may have an increased risk of second cancers.
- 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 that parents of children who are treated for neuroblastoma talk with their doctors about the possible late effects caused by some treatments. See the PDQ summary on Late Effects of Treatment for Childhood Cancer for more information.
Five types of standard treatment are used:
Surgery is used to treat neuroblastoma unless it has spread to other parts of the body. Depending on where the tumor is, as much of the tumor as is safely possible will be removed. If the tumor cannot be removed, a biopsy may be done instead.
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. External radiation therapy is used to treat neuroblastoma.
High-risk neuroblastoma that comes back after initial treatment is sometimes treated with mIBG (radioactive iodine therapy). Radioactive iodine is given through an intravenous (IV) line and enters the bloodstream which carries radiation directly to tumor cells. Radioactive iodine collects in neuroblastoma cells and kills them with the radiation that is given off.
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 cerebrospinal fluid, 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.
See Drugs Approved for Neuroblastoma for more information.
High-dose chemotherapy and radiation therapy with stem cell rescue
High-dose chemotherapy and radiation therapy with stem cell rescue is a way of giving high doses of chemotherapy and radiation therapy and replacing blood -forming cells destroyed by cancer treatment for high-risk neuroblastoma. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient 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.
Maintenance therapy is given after high-dose chemotherapy and radiation therapy with stem cell rescue to kill any cancer cells that may regrow and cause the disease to come back. Maintenance therapy is given for 6 months and includes the following treatments:
- Isotretinoin: A vitamin -like drug that slows the cancer's ability to make more cancer cells and changes how these cells look and act. This drug is taken by mouth.
- Anti-GD2 antibody ch14.18: A type of monoclonal antibody therapy that uses an antibody (ch14.18) made in the laboratory from a single type of immune system cell. ch14.18 identifies and attaches to a substance, called GD2, on the surface of neuroblastoma cells. Once the ch14.18 attaches to the GD2, a signal is sent to the immune system that a foreign substance has been found and needs to be killed. Then the body's immune system kills the neuroblastoma cell. This drug is given by infusion.
- Granulocyte-macrophage colony-stimulating factor (GM-CSF): A cytokine that helps make more immune system cells, especially granulocytes and macrophages (white blood cells), which can attack and kill cancer cells.
- Interleukin-2 (IL-2): A type of biologic therapy that boosts the growth and activity of many immune cells, especially lymphocytes (a type of white blood cell). Lymphocytes can attack and kill cancer cells.
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.
Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Tyrosine kinase inhibitor (TKI) therapy is one type of targeted therapy being studied in the treatment of neuroblastoma.
TKI therapy blocks signals needed for tumors to grow. TKIs block the enzyme, tyrosine kinase, that causes stem cells to become more white blood cells (granulocytes or blasts) than the body needs. Crizotinib is one of the TKIs being studied to treat neuroblastoma that has come back after treatment. TKIs may be used in combination with other anticancer drugs as adjuvant therapy (treatment given after the initial treatment, to lower the risk that the cancer will come back).
Vaccine therapy is a type of biologic therapy. Biologic therapy is a treatment that uses the patient’s immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body’s natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy.
Other drug therapy
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 listing of clinical trials.
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 child's condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.
