After Brain Tumor Treatment in Children

During treatment for a brain tumor, most people are focused on getting through treatment and managing side effects. After treatment, the focus tends to shift toward the long-term effects of the tumor and its treatment and worries about the tumor still being present or coming back.

It’s normal to want to put the tumor and its treatment behind you and get back to a life that does not revolve around it. Getting the right follow-up care offers the best chance for recovery and long-term survival.

Follow-up care after a brain or spinal cord tumor

For several years after treatment, regular follow-up exams will be very important. Talk with the cancer care team about developing a survivorship care plan. This plan can guide your next steps after treatment.

What’s usually in a survivorship care plan

A survivorship care plan might include:

  • A summary of the diagnosis, tests done, and treatment given
  • A suggested schedule for follow-up exams and tests
  • A schedule for other tests that might be needed in the future, such as early detection (screening) tests for other types of cancer, or tests to look for long-term health effects from the brain tumor or its treatment
  • A list of possible late- or long-term side effects from treatment, including what to watch for and when to contact the doctor
  • Diet and physical activity suggestions

What to expect during follow-up visits

Whether the tumor was removed completely or not, your cancer care team will want close follow up, especially in the first few months or years after treatment. They will watch any tumor or scar tissue left after treatment for signs of the tumor coming back. They will also check for short-term and long-term side effects of treatment as part of these visits.

Follow-up visits may include:

  • An exam that includes checking feeling (sensation), strength, balance, walking, and reflexes
  • Imaging tests such as MRI scans
  • Blood tests such as blood counts, hormone levels, and kidney and liver function tests
  • Hearing test (audiogram)
  • Vision test (this may be done by a specialist such as an optometrist or ophthalmologist)
  • Cognitive test (to test how well the brain can learn, make memories, and perform tasks)
  • Ultrasound of the heart (echocardiogram)
  • Cancer screening tests

If treatment caused any damage to the brain, especially to parts important for walking, talking, or moving the arms and legs, physical therapy and rehabilitation may also be an important part of recovery after treatment.

Visits with the cancer care team will be frequent at first, but the time between visits may get longer as time passes. The risk of recurrence usually goes down over time. However, for some types of brain tumors the risk of the tumor coming back can last for many years. Ask your cancer care team about the specific type of tumor, how long imaging tests to check the brain may be needed, and the risk of the tumor coming back.

Even as the risk of recurrence goes down, routine doctor visits are still important because some side effects of treatment might not show up until years later. Follow-up care gives you a chance to discuss any questions or concerns that arise during and after recovery from cancer treatment.

Questions to ask your care team

  • What type of follow-up will we need after treatment?
  • How often will follow-up exams and tests be needed?
  • Are there any limits on activities?
  • How will we know if the tumor has come back? What should we watch for?
  • Are there nearby support groups or other families who have been through this that we could talk to?

Staying prepared and organized

Even if treatment is completed, it’s still important to be organized and stay on top of your (child’s) health. Keeping records and health insurance coverage makes it easier to manage follow-up care, future checkups, and any new concerns that may come up.

Keep health insurance

It’s very important to keep health insurance as a brain tumor survivor. As children grow into adults, they will need their own coverage. It can help cover the cost of follow-up visits, tests, and any care needed in the future. No one wants to think about the cancer coming back, but it’s best to be prepared.

Save medical records

Keep copies of medical records so details of the cancer diagnosis and treatment can be shared easily when needed. As children grow into adults, these records become especially important for managing their own health care and seeing new doctors who do not know their cancer history.

Late and long-term effects of treatment

Brain tumor treatments can affect a person’s health later in life. Most long-term side effects depend on the type of treatment, where the tumor was located, and how old the person was during treatment. Young people are at risk of developing late effects of their treatment as they have more expected years ahead of them.

The risk of long-term effects depends on many factors such as the location of the tumor, treatments used, and the age of the person during treatment.

Late effects of treatment may include:

Treatment that includes surgery or radiation therapy to the brain or some types of chemotherapy (such as methotrexate) may affect learning ability in some children and teens. Because of this, doctors try to avoid radiation in very young children, and limit these treatments in others, as much as possible. Children and young adults treated for brain tumors may need extra support in school. As they grow up, they may need assistance living independently as adults.

Some cancer treatments can affect a child’s growth, so they might end up a bit shorter as adults. This is especially true after surgery to the pituitary gland, radiation treatment or stem cell transplants. Treatment can affect hormone levels, which can affect growth and increase the risk of health issues such as thyroid problems, obesity, high cholesterol, and diabetes.

The bones, muscles, and soft tissues may not grow as well after treatment with radiation. Doctors will monitor growth and development, with special attention to areas that were treated with radiation. In some cases, scoliosis, or a curve in the spine, can develop after treatment. This may need to be watched with x-rays, treated with bracing, or, in rare cases, may need surgery to correct.

Alkylating chemotherapy drugs (such as cyclophosphamide), platinum chemotherapy drugs (such as cisplatin or carboplatin), stem cell transplant, and surgery or radiation to the brain (especially near the pituitary gland) can affect sexual development and the ability to have children later in life. Talk to the cancer care team about the risks of infertility with treatment and ask about options for preserving fertility, such as sperm banking or egg freezing. For more information, see Preserving Fertility in Children and Teens with Cancer.

Changes in hormones can also affect sexual desire or pleasure. Low sex hormone levels can also have impacts on bone health, hair growth, energy, and your brain’s ability to create new memories or complete a task.

Radiation treatments used for brain tumors and certain chemotherapy drugs (such as etoposide and cyclophosphamide) can increase the risk of other types of cancer as survivors get older. The specific types of cancer depends on which treatments were needed and where radiation was given. For example, children and young adults who get spine radiation are at a higher risk of colon cancer at younger ages. Doctors recommend starting cancer screening tests early. Children who get radiation to the brain are at a higher risk of developing other brain tumors or tumors of the meninges that cover the brain, called meningiomas.

Anyone who gets radiation treatment has a higher risk of skin cancer and should check their skin often.

Radiation to the spine, used for some children and young adults with brain or spinal cord tumors, can cause heart problems later in life. For some survivors, an echocardiogram (an ultrasound of the heart) may be recommended every few years to check heart function and catch problems early.

Children treated with brain radiation are at higher risk of having cataracts, or clouding of the lens of the eye. Doctors recommend a yearly visit with an eye specialist to check vision.

People treated with platinum chemotherapy, such as cisplatin and carboplatin, or brain radiation are at increased risk of developing hearing problems. A test called an audiogram will likely be done during and after treatment to assess any damage. Hearing is very important for speech and social development in young children. If hearing has been affected, your cancer care team may recommend seeing an audiologist (hearing specialist) to discuss hearing aids.

Treatment for a brain tumor can result in scars after surgery or cause the bones and soft tissues to grow differently after radiation treatment.

People who get radiation to the brain or stem cell transplant may have trouble growing hair in areas where radiation was given.

Chemo drugs such as cisplatin and carboplatin can affect the kidneys. Regular kidney function testing may be recommended by your cancer care team to find and manage any kidney problems after treatment.

Children treated with radiation to the brain and spinal cord can have thyroid problems. Children with pituitary tumors treated with surgery are also at risk of hormone problems, such as problems with the thyroid.

Some people can develop neuropathy, or damage to the nerves that control how the body moves and feels, after treatment with drugs such as vincristine, or platinum chemotherapy (cisplatin or carboplatin). Symptoms of neuropathy, such as numbness, tingling, or tripping while walking often go away or get better once treatment is done. For some people, these symptoms may be lifelong.

Emotional and social health in children and families affected by brain tumors

Once treatment is finished, emotional concerns can come up. Some might occur many years after treatment and can include:

  • Dealing with physical changes that can result from the treatment
  • Worries about the cancer returning or new health problems developing
  • Feelings of resentment for having had cancer or having had to go through treatment or having health problems when others do not
  • Feeling guilty for surviving cancer, when other friends with cancer did not
  • Concerns about being treated differently or discriminated against by friends, classmates, coworkers, employers, or others
  • Concerns about dating, marrying, and having a family later in life

It’s normal to have some anxiety or other emotional reactions after treatment. But feeling overly worried, depressed, or angry can affect many aspects of a young person’s growth. It can get in the way of relationships, school, work, and other aspects of life. With support from family, friends, other survivors, mental health professionals, and others, many people who have survived cancer can thrive despite the challenges they have had to face.

Parents and other family members, especially siblings, can also be affected, both emotionally and in other ways. Some common family concerns include financial stresses, job loss or relationship stress during treatment, and worry about cancer returning. Social workers and other professionals at cancer centers can help families find support. Reach out to your child’s cancer center for help when needed.

Long-term follow-up guidelines

To help increase awareness of late effects and improve follow-up care for childhood and adolescent cancer survivors throughout their lives, the Children’s Oncology Group (COG) has developed long-term follow-up guidelines for survivors of childhood cancers. These guidelines are used by doctors to create a survivorship care plan specific to your child or teen and their treatment. They can help you know what to watch for, what types of screening tests should be done to look for problems, and how late effects can be treated.

To learn more, ask your doctor about the COG survivor guidelines. You can also read them on the COG website: www.survivorshipguidelines.org. The guidelines are written for health care professionals, but patient education materials on some late effects of treatment are available on the site as well (as “Health Links”).
