In general, cancer in children is uncommon. This means it can be hard for doctors to plan treatments unless they know what has been most effective in other children. That’s why more than 60% of children with cancer are treated as part of a clinical trial.
Clinical trials are research studies that compare the standard of care with newer approaches to treatments that may be more effective. The “standard of care” is the best treatments known. Clinical trials may test such approaches as a new drug, a new combination of standard treatments, or new doses of current therapies. The health and safety of all children participating in clinical trials are closely monitored.
To take advantage of these newer treatments, children with cancer should be treated at a specialized cancer center. Doctors at these centers have extensive experience in treating children with cancer and have access to the latest research. A doctor who specializes in treating children with cancer is called a pediatric oncologist. If a pediatric cancer center is not nearby, general cancer centers sometimes have pediatric specialists who are able to be part of your child’s care.
In many cases, a team of doctors treats a child with cancer; this is called a multidisciplinary team. Pediatric cancer centers often have extra support services for children and their families, such as child life specialists, dietitians, physical and occupational therapists, social workers, and counselors. Special activities and programs to help your child and family cope may also be available.
Making treatment decisions
Treatment options and recommendations depend on several factors, including:
The size and location of the tumor
Whether the cancer has spread
Possible side effects
The child’s overall health
The treatment is tailored according to the assigned risk group. Descriptions of the most common treatment options for neuroblastoma are listed below.
Your child’s care plan may also include treatment for symptoms and side effects, an important part of cancer care. Take time to learn about all of your child’s treatment options and be sure to ask questions about things that are unclear. Also, talk about the goals of each treatment with your child’s doctor and what your child can expect while receiving the treatment.
Learn more about making treatment decisions.
Surgery is the removal of the tumor and some surrounding healthy tissue during an operation. A surgical oncologist is a doctor who specializes in treating cancer using surgery. If the cancer has not spread, surgery can sometimes be used to remove the entire tumor. However, most neuroblastoma is not found until after the cancer has spread. In that situation, the doctor removes as much of the tumor as possible during surgery.
Even if a tumor cannot be removed because of its location, a surgical biopsy (see Diagnosis) may still be done to determine the type of tumor.
If the tumor cannot be completely removed, the child may receive radiation therapy and chemotherapy (see below) to destroy the remaining cancer cells. In addition, the doctor may take a biopsy of the liver to find out if the disease has spread to the liver.
Talk with your child’s surgeon about the possible side effects of the surgery and how they will be relieved or managed. Learn more about the basics of cancer surgery.
Chemotherapy is the use of drugs to destroy cancer cells, usually by stopping the cancer cells’ ability to grow and divide. Chemotherapy is given by a pediatric oncologist or a medical oncologist, a doctor who specializes in treating cancer with medication.
Systemic chemotherapy gets into the bloodstream to reach cancer cells throughout the body. Common ways to give chemotherapy include an intravenous (IV) tube placed into a vein or muscle using a needle or in a pill or capsule that is swallowed. A chemotherapy regimen (schedule) usually consists of a specific number of cycles given over a set period of time.
Most children with neuroblastoma will need to have chemotherapy. Chemotherapy may be used as the primary treatment for neuroblastoma. Or, it may be given before surgery to shrink the tumor or after surgery to destroy any remaining cancer cells.
Children with intermediate-risk neuroblastoma often receive the following drugs:
Children with high-risk neuroblastoma often receive the following drugs:
Busulfan (Busulfex, Myleran)
Cytokines (GM-CSF and IL2)
Doxorubicin (Adriamycin, Doxil)
Etoposide (VePesid, Toposar)
The side effects of chemotherapy depend on the individual and the dose used, but they can include fatigue, risk of infection, nausea and vomiting, hair loss, loss of appetite, and diarrhea. These side effects usually go away once treatment is finished. The severity of the side effects depends on the type and amount of the drug being given and the length of time the child receives the drug.
Learn more about the basics of chemotherapy and preparing for treatment. The medications used to treat cancer are continually being evaluated. Talking with your child’s doctor is often the best way to learn about the medications prescribed for you, their purpose, and their potential side effects or interactions with other medications. Learn more about your prescriptions by using searchable drug databases.
Radiation therapy is the use of high-energy x-rays or other particles to destroy cancer cells. A doctor who specializes in giving radiation therapy to treat cancer is called a radiation oncologist. The most common type of radiation treatment is called external-beam radiation therapy, which is radiation given from a machine outside the body.
A radiation therapy regimen (schedule) usually consists of a specific number of treatments given over a set period of time. Side effects from radiation therapy may include fatigue, mild skin reactions, upset stomach, and loose bowel movements. Most side effects go away soon after treatment is finished. Talk with the radiation oncologist about side effect you can expect, and how they will be managed.
Because radiation therapy can sometimes cause problems with the normal growth and development of a child’s brain and the ovaries in girls or testicles in boys, the doctor may choose to treat the cancer in another way.
Learn more about the basics of radiation therapy.
Stem cell transplantation/bone marrow transplantation
A stem cell transplant is a medical procedure in which diseased bone marrow is replaced by highly specialized cells, called hematopoietic stem cells. Hematopoietic stem cells are blood-forming cells found both in the blood stream and in the bone marrow.
Today, this procedure is more commonly called a stem cell transplant, rather than a bone marrow transplant. That’s because it is the blood stem cells that are typically being transplanted, not the actual bone marrow tissue.
Before recommending transplantation, doctors will talk with the patient about the risks of this treatment and consider several other factors, such as the type of cancer, results of any previous treatment, and the patient’s age and general health.
There are 2 types of stem cell transplantation depending on the source of the replacement blood stem cells: allogeneic (ALLO) and autologous (AUTO). AUTO transplants are most often used for children with high-risk neuroblastoma.
In an AUTO transplant, the patient’s own stem cells are used. The stem cells are obtained from the patient when he or she is in remission from previous treatment. The stem cells are then frozen until they are needed, usually after the high-dose treatment (explained below) is completed.
The goal of transplantation is to destroy cancer cells in the marrow, blood, and other parts of the body and allow replacement blood stem cells create healthy bone marrow. In most stem cell transplants, the patient is treated with high doses of chemotherapy and/or radiation therapy to destroy as many cancer cells as possible. This also destroys the patient’s bone marrow tissue and suppresses the patient’s immune system. After the high-dose treatment is given, blood stem cells are infused into the patient’s vein to replace the bone marrow and restore normal blood counts.
Different combinations of high-dose chemotherapy have been used before the stem cells are infused. European studies suggest that busulfan and melphalan may cause fewer side effects and may also be more effective than carboplatin, etoposide, and melphalan. The Children’s Oncology Group has tested the safety and efficiency of busulfan and melphalan followed by stem cell rescue in a clinical trial. The Children’s Oncology Group has another study comparing a single cycle of high-dose chemotherapy with carboplatin, etoposide, and melphalan versus tandem cycles of high-dose chemotherapy, consisting of cyclophosphamide and thiotepa with stem cell rescue followed by carboplatin, etoposide, and melphalan with stem cell rescue. Stem cell rescue means the child’s stem cells are replaces with healthy cells. There was improved event-free survival in patients in a study who received tandem cycles of high-dose therapy and stem cell transplant.
In stem cell transplantation, the replacement cells engraft, or begin to make new blood cells, and turn into healthy, blood-producing tissue in 10 days to 3 weeks. Destroying the patient’s own marrow reduces the body’s natural defenses, temporarily leaving the patient at an increased risk of infection. Until the patient’s immune system is back to normal, patients may need antibiotics and blood transfusions. They also need to follow certain safety restrictions provided by the health care team to help avoid infections.
In an AUTO transplant, there is little risk of tissue rejection because the replacement stem cells are the patient’s own cells. However, there is a risk in an autologous transplant that some of the cells that are put back into the patient could still be cancerous.

Retinoids are substances that are similar to vitamin A. They are thought to help some cells mature into normal cells. When chemotherapy no longer works for some tumor cells, 13-cis-retinoic acid (RA) or isotretinoin has been given to children with high-risk neuroblastoma after completion of consolidation therapy, which is treatment given after the initial treatment. A Children’s Oncology Group study showed that when children who were in remission following a stem cell transplant were given RA, their risk of recurrence was reduced.
Immunotherapy is designed to boost the body’s natural defenses to fight the cancer. It uses compounds made either by the body or in a laboratory to bolster, target, or restore immune system function.
GD2 is a compound on the surface of cells, called a disialoganglioside, that is found in large amounts in most neuroblastomas. A variety of monoclonal antibodies directed against GD2 have been used to treat patients with neuroblastoma. A monoclonal antibody is a substance made in a laboratory that acts like the antibodies the body’s immune system naturally makes to fight diseases such as a tumor.
The Children's Oncology Group has used antibody therapy combined with cytokines, which are proteins that stimulate the immune system, and retinoid therapy (see above) for patients with high-risk neuroblastoma that:
Responded to induction (first) chemotherapy, and
Who have had a stem cell transplantation without the neuroblastoma growing or spreading.
In a Children’s Oncology Group clinical trial, children without evidence of active disease following stem cell transplantation and radiation received either RA alone, or RA and anti-GD2 monoclonal antibody dinutuximab (Unituxin) and cytokines. The patients who received the immunotherapy and RA lived longer and had fewer recurrences than those who were treated with RA alone. Immunotherapy and RA is now a part of the standard treatment for patients with high-risk neuroblastoma. Based on the results of this study, the U.S. Food and Drug Administration (FDA) approved dinutuximab (Unituxin) in March 2015 as part of first-line therapy for children with high-risk neuroblastoma.
Learn more about the basics of immunotherapy.
Targeted delivery of radionuclides
A radionuclide called 131I MIBG is being researched to treat neuroblastoma. 131I MIBG has led to responses in about 30% of children with recurrent neuroblastoma. Based on how efficient this drug is when there is a recurrence, a new clinical trial has been opened by the Children’s Oncology Group testing 131I MIBG plus stem cell rescue combined with busulfan-melphalan and stem cell transplantation in patients newly diagnosed with high-risk disease. The results of this study are currently being studied.
Remission and the chance of recurrence
A remission is when a tumor cannot be detected in the body and there are no symptoms. This may also be called having “no evidence of disease” or NED.
A remission may be temporary or permanent. This uncertainty causes many people to worry that their cancer will come back. While many remissions are permanent, it’s important to talk with your doctor about the possibility of the tumor returning. Understanding your child’s risk of recurrence and the treatment options may help you and your family feel more prepared if the cancer does return. Learn more about coping with the fear of recurrence.
If the cancer does return after the original treatment, it is called a recurrent or relapsed cancer. It may come back in the same place (called a local recurrence), nearby (regional recurrence), or in another place (distant recurrence). If there is a recurrence, the cancer may need to be staged again using the system described in stages and groups.
When this occurs, a cycle of testing will begin again to learn as much as possible about the recurrence. After testing is done, you and your child’s doctor will talk about the treatment options. Often the treatment plan will include the treatments described above, such as surgery, chemotherapy, and radiation therapy, but they may be used in a different combination or given at a different pace. Your child’s doctor may also suggest clinical trials that are studying new ways to treat this type of recurrent tumor.
Treatment of recurrent neuroblastoma
The treatment of recurrent neuroblastoma depends on where the tumor recurred, the previous treatment, tumor biology and the possible gene mutations. While there are treatments that work well for patients with low-risk and intermediate-risk disease who have a recurrence where the original tumor started, recurrent high-risk neuroblastoma remains difficult to cure completely. Neuroblastoma comes back in approximately 50% of children with high-risk disease.
Over the past several years, more new treatments and combinations have been developed for these patients:
Chemotherapy alone and in combination with dinutuximab. The drugs irinotecan (Camptosar) and topotecan are often used early when there is a recurrence. The combination of irinotecan and temozolomide (Methazolastone, Temodar) has few side effects. This chemotherapy treatment regimen has been evaluated in a Children’s Oncology Group study. Some recurrent tumors respond to this treatment. Other chemotherapy regimens have been used when there is a recurrence, including topotecan and low-dose cyclophosphamide. Recent results of a Children’s Oncology Group clinical trial evaluating the activity of the combination of chemotherapy (irinotecan and temozolomide) plus dinutuximab have shown promising results.
Targeted delivery of radionuclides. As explained above, radionuclides have been attached to MIBG, as well as somatostatin analogs, which are substances similar to a specific hormone produced by cells, and anti-GD2 antibodies. Early studies looking at combinations of radio-labeled MIBG and radiation sensitizers like irinotecan or histone deacetylase inhibitors like vorinostat (Zolinza) are ongoing. Radiosensitizers are drugs that make tumor cells more sensitive to radiation therapy, making radiation therapy more effective.
Immunotherapy. A humanized antibody directed against the GD2 linked with interleukin-2 (IL2), which is a substance that can be used to boost the immune system, is being evaluated for patients with recurrent neuroblastoma. Other monoclonal antibodies directed against the GD2 antigen are also being evaluated. The combination of the immune-modulating agent lenolinomide and dinutuximab is currently being tested in an ongoing Phase I clinical trial. Vaccines against tumor cell DNA, function, and structure, as well as use of immune cells created in the laboratory that can destroy tumor cells, are also being researched.
Retinoids. Fenretinide works against neuroblastoma in a laboratory, even when other retinoids do not. Research shows that the drug has few side effects. Newer versions of this drug are being created to make it easier to give this medication to young children.
Angiogenesis inhibitors. Anti-angiogenesis therapy is focused on stopping angiogenesis, which is the process of making new blood vessels from existing blood vessels. Because a tumor needs the nutrients delivered by blood vessels to grow and spread, the goal of anti-angiogenesis therapies is to “starve” the tumor.
Tyrosine kinase inhibitors. Tyrosine kinase inhibitors are drugs that block cell communication and can stop tumor growth. Drugs that inhibit ALK are being tested in clinical trials. Other tyrosine kinase inhibitors that are being tested in clinical trials include inhibitors of the epidermal growth factor receptor (EGFR) and the insulin growth factor 1 receptor (IGR1R). These receptors help tumor cells grow and blocking them may slow or stop neuroblastoma growth.
Aurora kinase inhibitors. Aurora A kinase helps cells divide early on and is found in all cells that are dividing. Aurora kinase inhibitors are drugs that block this protein, stopping or slowing the cells from dividing. Inhibition of Aurora A kinase also destabilizes the MYCN protein. An Aurora A kinase inhibitor is currently being evaluated in combination with irinotecan and temozolomide in an early-phase clinical trial for patients with recurrent neuroblastoma.
Other treatment options. Demethylating drugs such as decitabine (Dacogen) are currently being studied. Histone deacetylase inhibitors, which are substances that can prevent a tumor from growing and spreading, have also shown some promise as a treatment for neuroblastoma. At least 3 histone deacetylase inhibitors are now being studied in clinical trials for patients with a refractory solid tumor, which is a tumor that remains after the initial treatment.
An inhibitor of a key downstream target of MYCN, ornithine decarboxylase (ODC), is also being tested in early phase neuroblastoma clinical trials.
The New Approaches to Neuroblastoma Therapy (NANT) Phase I Consortium has a number of open clinical trials testing new treatments for children with recurrent or refractory neuroblastoma. Several studies are testing combination therapy that includes biologic agents plus chemotherapy.
Whichever treatment plan you choose, palliative care will be important for relieving symptoms and side effects.
When a child has a recurrent tumor, family members often experience emotions such as disbelief or fear. Families are encouraged to talk with the health care team about these feelings and ask about support services to help them cope. Learn more about dealing with cancer recurrence.
If treatment fails
Although treatment is successful for the majority of children with cancer, sometimes it is not. If a child’s cancer cannot be cured or controlled, this is called an advanced or terminal cancer. This diagnosis is stressful, and advanced cancer may be difficult to discuss. However, it is important to have open and honest conversations with your child’s doctor and health care team to express your family’s feelings, preferences, and concerns. The health care team is there to help, and many team members have special skills, experience, and knowledge to support patients and their families.
Parents or guardians are encouraged to think about where the child would be most comfortable: at home, in a home-like setting elsewhere, in the hospital, or in a hospice environment.
Hospice care is a type of palliative care for people who are expected to live less than 6 months. It is designed to provide the best possible quality of life for people who are near the end of life. Nursing care and special equipment can make staying at home a workable alternative for many families.
Some children may be happier if they can arrange to attend school part-time or keep up other activities and social connections. The child’s health care team can help parents or guardians decide on an appropriate level of activity. Making sure a child is physically comfortable and free from pain is extremely important as part of end-of-life care. Learn more about caring for a terminally ill child and advanced cancer care planning.
The death of a child is an enormous tragedy, and families may need support to help them cope with the loss. Pediatric cancer centers often have professional staff and support groups to help with the process of grieving. Learn more on grieving the loss of a child.
