Our 24/7 cancer helpline provides information and answers for people dealing with cancer. We can connect you with trained cancer information specialists who will answer questions about a cancer diagnosis and provide guidance and a compassionate ear.
Our highly trained specialists are available 24/7 via phone and on weekdays can assist through video calls and online chat. We connect patients, caregivers, and family members with essential services and resources at every step of their cancer journey. Ask us how you can get involved and support the fight against cancer. Some of the topics we can assist with include:
For medical questions, we encourage you to review our information with your doctor.
Chemotherapy (chemo) is the use of anti-cancer drugs, which are usually given into a vein. The drugs enter the bloodstream and travel throughout the body to reach and destroy cancer cells. This makes chemo useful for treating neuroblastoma, especially if it can’t all be removed with surgery.
Whether a child with neuroblastoma will get chemotherapy depends on their risk group, which is based on the stage (extent) and location of the cancer, the child’s age, and other factors.
Some children with neuroblastoma are treated with chemo either before surgery (neoadjuvant chemotherapy) or after surgery (adjuvant chemotherapy).
In other cases, especially when the cancer has spread too far to be removed completely by surgery, chemo is the main treatment.
Chemo for neuroblastoma usually includes a combination of drugs. The main chemo drugs used include:
The most common combination of drugs includes cisplatin (or carboplatin), cyclophosphamide, doxorubicin, vincristine, and etoposide, but others may be used.
For children in the high-risk group, other drugs might be added as well, and some drugs might be given at higher doses. This may be followed by a stem cell transplant.
Doctors give chemo in cycles. Treatment is given for a few days in a row, followed by time off to allow the body time to recover. The cycles are typically repeated every 3 or 4 weeks. The total length of treatment depends on which risk group the child is in – higher risk groups usually require longer treatment.
Chemo drugs can affect other cells in the body that are dividing quickly, which can lead to side effects. The side effects of chemo depend on the type and dose of drugs given and the length of time they are taken.
Side effects common to many chemo drugs include:
Chemo can damage the bone marrow, where new blood cells are made. This can lead to low blood cell counts, which can result in:
Most of these side effects tend to go away after treatment is finished. There are often ways to lessen these side effects. For example, drugs can be given to help prevent or reduce nausea and vomiting. Be sure to ask your child’s doctor or nurse about medicines to help reduce side effects, and let them know if your child has side effects so they can be managed.
Along with the effects listed above, some drugs can have specific side effects. For example:
Cyclophosphamide can damage the bladder, which can cause blood in the urine. The risk of this can be lowered by giving the drugs with plenty of fluids and with a drug called mesna, which helps protect the bladder. This drug can also damage the ovaries or testicles, which could affect fertility (the ability to have children).
Doxorubicin can damage the heart. Doctors try to reduce this risk as much as possible by limiting the doses of doxorubicin and by checking the heart with an echocardiogram (an ultrasound of the heart) during treatment. This drug can also cause skin damage if it should leak out of the vein while it is being given.
Cisplatin and carboplatin can affect the kidneys. Giving plenty of fluids can help reduce this risk. These drugs can also affect hearing. Your child’s doctor may order hearing tests (audiograms) during or after treatment.
Vincristine and etoposide can cause nerve damage (neuropathy). Some patients may have tingling, numbness, weakness, or pain, particularly in the hands and feet.
Chemotherapy can also have some longer-term side effects. For example, some drugs can increase the risk of later developing another type of cancer (such as leukemia). While this is a serious risk, it is not common, and the small increase in risk has to be weighed against the importance of chemotherapy in treating neuroblastoma.
