Craniopharyngioma - Childhood - Introduction
ON THIS PAGE: You will find some basic information about this disease and the parts of the body it may affect. This is the first page of Cancer.Net’s Guide to Childhood Craniopharyngioma. Use the menu to see other pages. Think of that menu as a roadmap for this entire guide.
Craniopharyngioma is a type of central nervous system (CNS) tumor . A CNS tumor may be either cancerous or benign. A cancerous tumor is malignant, meaning it is usually fast-growing and can spread to other parts of the body. A benign tumor means the tumor is usually slower-growing and will not spread. Craniopharyngioma is considered a benign tumor, which means that it is usually slow-growing and very unlikely to spread.
About the central nervous system
The brain and spinal cord make up the CNS, where all vital functions of the body are controlled. The brain is the center of thought, memory, and emotion. It controls the 5 senses, which are smell, touch, taste, hearing, and sight. It also controls movement and other basic body functions, including consciousness, heartbeat, circulation, and breathing. The spinal cord is made up of nerves that carry information from the body to the brain and from the brain to the body.
Craniopharyngioma usually occurs in a part of the brain called the suprasellar region. This region is the area of the brain just above the pituitary gland. The pituitary gland is an important gland and is often called the “master endocrine gland” because it produces several different hormones that regulate many body functions. The optic nerves and a gland called the hypothalamus are located nearby. The hypothalamus regulates hunger, body temperature, thirst, sleep, fatigue, and other behaviors.
About craniopharyngioma
Craniopharyngioma is a slow-growing tumor that may be present for many years before it is found. It may be solid and/or cystic. A cystic tumor has a closed pouch or sac that contains fluid made by the tumor. The solid part often contains areas of calcium that can easily be seen on a computed tomography (CT) scan (see Diagnosis ). The cystic part of the tumor often contains very high amounts of protein.
This section covers craniopharyngioma that occurs in children. For information about craniopharyngioma in adults, read the guide to adult brain tumors .

Craniopharyngioma - Childhood - Statistics
ON THIS PAGE: You will find information about the estimated number of children who will be diagnosed with craniopharyngioma each year. You will also read general information on surviving the disease. Remember, survival rates depend on several factors, and no 2 people are the same. Use the menu to see other pages.
Every person is different, with different factors influencing their risk of being diagnosed with this tumor and the chance of recovery after a diagnosis. It is important to talk with your doctor about any questions you have around the general statistics provided below and what they may mean for your child individually. The original sources for these statistics are provided at the bottom of this page.
How many children are diagnosed with craniopharyngioma?
In 2023, an estimated 130 children under the age of 15 in the United States will be diagnosed with craniopharyngioma. This type of tumor is diagnosed most often between the ages of 5 and 14, but it is possible for a person of any age to be diagnosed with craniopharyngioma.
What is the survival rate for craniopharyngioma?
There are different types of statistics that can help doctors evaluate a child’s chance of recovery from craniopharyngioma. These are called survival statistics. A specific type of survival statistic is called the relative survival rate. It is often used to predict how having a tumor may affect life expectancy. Relative survival rate looks at how likely people with craniopharyngioma are to survive for a certain amount of time after their initial diagnosis or start of treatment compared to the expected survival of similar people without this tumor.
Example: Here is an example to help explain what a relative survival rate means. Please note this is only an example and not specific to this type of tumor. Let’s assume that the 5-year relative survival rate for a specific type of tumor is 90%. “Percent” means how many out of 100. Imagine there are 1,000 people without this tumor, and based on their age and other characteristics, you expect 900 of the 1,000 to be alive in 5 years. Also imagine there are another 1,000 people similar in age and other characteristics as the first 1,000, but they all have the specific type of tumor that has a 5-year survival rate of 90%. This means it is expected that 810 of the people with the specific tumor (90% of 900) will be alive in 5 years.
It is important to remember that statistics on the survival rates for children with craniopharyngioma are only an estimate. They cannot tell an individual person if the tumor will or will not shorten their life. Instead, these statistics describe trends in groups of people previously diagnosed with the same disease, including specific stages of the disease.
The 5-year relative survival rate for children under the age of 15 with craniopharyngioma in the United States is 96%.
The survival rates for craniopharyngioma vary based on several factors. These include age and general health, and how well the treatment plan works.
Experts measure relative survival rate statistics for craniopharyngioma every 5 years. This means the estimate may not reflect the results of advancements in how craniopharyngioma is diagnosed or treated from the last 5 years. Talk with your child’s doctor if you have any questions about this information. Learn more about understanding statistics .

The next section in this guide is Risk Factors . It describes how there are currently no known factors linked with an increased chance of developing craniopharyngioma. Use the menu to choose a different section to read in this guide.
Craniopharyngioma - Childhood - Risk Factors
A risk factor is anything that increases a person’s chan c e of developing a tumor. The cause of a craniopharyngioma is not known, and there are no proven risk factors.
The next section in this guide is Symptoms and Signs . It explains what changes or medical problems craniopharyngioma can cause. Use the menu to choose a different section to read in this guide.
Craniopharyngioma - Childhood - Symptoms and Signs
ON THIS PAGE: You will find out more about the changes and medical problems that can be a sign of craniopharyngioma. Use the menu to see other pages.
Children with craniopharyngioma may experience one or more of the following symptoms or signs. Symptoms are changes that you can feel in your body. Signs are changes in something measured, like taking your blood pressure or doing a lab test. Together, symptoms and signs can help describe a medical problem. Sometimes, children with craniopharyngioma do not have any of the symptoms and signs described below. Or, the cause of a symptom or sign may be a medical condition that is not craniopharyngioma.
Symptoms of craniopharyngioma can be caused by hormonal changes, pressure building up in the brain, or by the tumor pressing on nerves or blood vessels, which can cause the brain to not function properly in those areas. Generally, craniopharyngioma is not diagnosed until a child has symptoms.
General symptoms include:
-
Headaches, which may be severe and worse in the early morning
-
Nausea and/or vomiting
-
Difficulty with balance
-
Increased sleepiness or fatigue
-
Mood or behavior changes
Location-specific symptoms of craniopharyngioma include:
-
Obesity or excessive weight gain
-
Excessive thirst and increased urination
-
Vision changes, blurriness, or loss of peripheral vision
-
Slow or halted body growth
-
Early or delayed puberty
If you are concerned about any changes your child experiences, please talk with your child’s doctor. Your doctor will try to understand what is causing your child’s symptom(s). They may do an exam and order tests to understand the cause of the problem, which is called a diagnosis.
If a central nervous system (CNS) tumor is diagnosed, relieving symptoms remains an important part of your child’s care and treatment. Managing symptoms may also be called "palliative or supportive care," which is not the same as hospice care given at the end of life. You can receive palliative and supportive care at any time during treatment. This type of care focuses on managing symptoms and supporting people who face serious illnesses, such as a brain tumor. Learn more in this guide’s section on Coping with Treatment .
Be sure to talk with the health care team about the symptoms your child experiences, including any new symptoms or a change in symptoms.
The next section in this guide is Diagnosis . It explains what tests may be needed to learn more about the cause of the symptoms. Use the menu to choose a different section to read in this guide.
Craniopharyngioma - Childhood - Diagnosis
ON THIS PAGE: You will find a list of common tests, procedures, and scans that doctors use to find the cause of a medical problem. Use the menu to see other pages.
Doctors use many tests to find, or diagnose, a tumor. Doctors may also do tests to learn which treatments could work best.
For most tumors, a biopsy is the only sure way for the doctor to know if an area of the body has a tumor. In a biopsy, the doctor takes a small sample of tissue for testing in a laboratory. If a biopsy is not possible, the doctor may suggest other tests that will help make a diagnosis.
How craniopharyngioma is diagnosed
Your child’s doctor may consider these factors when choosing a diagnostic test:
-
The type of tumor suspected
-
Your child’s signs and symptoms
-
Your child’s age and general health
-
The results of earlier medical tests
There are different tests used for diagnosing craniopharyngioma. Not all tests described here will be used for every child.
-
Physical examination . The doctor will examine your child’s head and body and ask questions about the symptoms they are experiencing and their medical history. This may include tests to check your child’s vision, growth and development, and brain function.
-
Blood and/or urine tests . The doctor may recommend different blood tests, including tests that measure the levels of certain hormones. If your child has excessive thirst and increased urination, the doctor may recommend a water deprivation test to evaluate the production of a hormone that helps concentrate urine.
-
Biopsy. A biopsy is the only way to make a definite diagnosis, even if other tests can suggest that a tumor is present. During biopsy, part or all of the tumor is removed for examination under a microscope. For craniopharyngioma, a neurosurgeon may remove a piece of the tumor or the entire tumor during an operation. A neurosurgeon is a doctor who specializes in central nervous system (CNS) surgery. Then, a pathologist examines the tissue removed during the surgery under a microscope to make a diagnosis. A pathologist is a doctor who specializes in interpreting laboratory tests and evaluating cells, tissues, and organs to diagnose disease. A neuropathologist is a pathologist who specializes in CNS tissues and diseases. Usually, the neurosurgeon will try to safely remove as much of the tumor as possible while limiting damage to the brain (see Types of T reatment ).
Imaging tests
Results of the physical examination and blood and/or urine tests may suggest that imaging tests are needed to look for craniopharyngioma. Imaging tests show pictures of the inside of the body. There are 2 main types of imaging tests used to find craniopharyngioma.
-
Computed tomography (CT or CAT) scan. A CT scan takes pictures of the brain using x-rays taken from different angles. A computer combines these pictures into a detailed, 3-dimensional image that shows abnormalities, including tumors. Sometimes, a special dye called a contrast medium is injected into a patient’s vein during the scan to provide better detail.
-
Magnetic resonance imaging (MRI). An MRI produces detailed images of the inside of the body using magnetic fields, not x-rays. An MRI can be used to measure the tumor’s size. Often, a special dye called a contrast medium is injected into a patient’s vein before the scan to create a clearer picture.
After diagnostic tests are done, your child’s doctor will review the results with you. This information will be used to recommend treatment options.
The next section in this guide is Stages . It explains that doctors do not commonly use stage to describe craniopharyngioma. Use the menu to choose a different section to read in this guide.
Craniopharyngioma - Childhood - Stages
ON THIS PAGE: You will learn that because of the nature of craniopharyngioma, doctors do not commonly use stage to describe this tumor. Use the menu to see other pages.
What is cancer staging?
In cancer, staging is typically how doctors describe the extent of disease in a person’s body. Craniopharyngiomas rarely, if ever, spread to other parts of the brain or elsewhere in the body far from where they started. Therefore, there is no standard staging system for this type of tumor.

ON THIS PAGE: You will learn about the different types of treatments doctors use for children with craniopharyngioma. Use the menu to see other pages.
To take advantage of the special expertise necessary to treat a brain tumor, children with a brain tumor should receive treatment at a specialized pediatric center. Doctors at these centers have extensive experience in treating children with brain tumors and have access to the latest technology. A doctor who specializes in treating children with a tumor is called a pediatric oncologist. A doctor who specializes in treating children with a brain tumor is called a pediatric neuro-oncologist. If a pediatric treatment center is not nearby, general cancer centers sometimes have pediatric specialists who are able to be part of your child’s care.
How craniopharyngioma is treated
In many cases, a team of doctors provides care to a child and their family. This is called a multidisciplinary team. Pediatric treatment centers often have extra support services for children and their families, such as child life specialists, nurse specialists, dietitians, physical therapists, occupational therapists, social workers, and counselors. Special activities and programs to help your child and family cope may also be available. Learn more about the types of clinicians who provide this type of care.
Treatment for craniopharyngioma is very often successful. The treatment plan used depends on whether the tumor can be completely removed with surgery. If the tumor cannot be completely removed, radiation therapy is usually recommended. However, the side effects of radiation therapy must be considered when deciding on the best treatment for very young children. Radiation therapy given to this area of the body can cause permanent learning and memory problems. Radiation therapy can also slow a child’s metabolism and decrease the levels of hormones needed for the body to function well. The doctors will consider several factors before recommending a treatment plan for your child.
There are treatments being studied in clinical trials for patients in whom the tumor cannot be completely removed surgically but who would like to avoid or delay radiation therapy. A clinical trial is a research study that tests a new approach to treatment. Talk with the doctor about whether this might be an option for your child.
Take time to learn about all of your child’s treatment options and be sure to ask questions about things that are unclear. Talk with your child’s doctor about the goals of each treatment and what your child can expect during treatment. These types of conversations are called “shared decision-making.” Shared decision-making is when you and the doctors work together to choose treatments that fit the goals of your child’s care. Learn more about making treatment decisions .
The common types of treatments used for craniopharyngioma are described below. Your child’s care plan may also include treatment for symptoms and side effects, an important part of care for a brain tumor. Learn more about preparing your child for treatment.

Surgery
Surgery is the most common treatment for craniopharyngioma. A neurosurgeon is a doctor who specializes in removing brain tumors, including craniopharyngioma.
The goal of surgery is to confirm the diagnosis and remove as much tumor as safely possible. Complete removal of craniopharyngioma may also be called a complete resection. This is possible for about 70% to 85% of children diagnosed with craniopharyngioma.
Possible side effects of surgery depend on the tumor’s location. Surgery may damage parts of the brain near the tumor, affecting hormone function, metabolism, vision, arm and leg movement, or consciousness. Sometimes, the tumor may have grown into major blood vessels or the optic chiasm, which is an area of the brain that controls vision. This can make it difficult to remove the tumor. Some tumors cannot be removed using surgery because of their location and can only have a small portion removed during a biopsy (see Diagnosis ). In this situation, the tumor is called inoperable, and the doctor will recommend treating the tumor another way.
The doctor may recommend additional treatment after surgery. Research studies have shown that people with craniopharyngioma that was partially removed who received radiation therapy live as long as those who had the tumor completely removed with surgery. In addition, they sometimes have fewer long-term side effects, such as obesity, hormone changes, stroke, severe bleeding, or damage to the hypothalamus.
Before surgery, talk with your child’s health care team about the possible side effects from the recommended surgery. Learn more about the basics of surgery .
Return to top
Radiation therapy
Radiation therapy is the use of high-energy x-rays or other particles to destroy tumor cells. A doctor who specializes in giving radiation therapy to treat a tumor 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. Because radiation therapy can affect the growth and development of a child’s brain, advanced treatment planning techniques should be used. These techniques can help lessen the amount of radiation given to the areas of the brain not affected by the tumor.
Radiosurgery is a way to deliver a single, high dose of radiation therapy to the tumor while sparing other areas of the brain. This technique requires a head frame so doctors know exactly where to deliver the radiation treatment. This type of radiation therapy is generally used for recurrent craniopharyngioma (see below).
Short-term side effects from radiation therapy may include fatigue, mild skin reactions, and nausea. Most side effects go away soon after treatment is finished. More permanent side effects can include hair loss, learning difficulties, low hormone levels, weight gain, and memory problems. Talk with your child's doctor about the possible short- and long-term effects of your child’s treatment plan.

Physical, emotional, social, and financial effects of craniopharyngioma
Craniopharyngioma and its treatment cause physical symptoms and side effects, as well as emotional, social, and financial effects. Managing all of these effects is called palliative and supportive care. It is an important part of your child’s care that is included along with treatments intended to slow, stop, or eliminate the tumor.
Palliative and supportive care focuses on improving how your child feels during treatment by managing symptoms and supporting patients and their families with other, non-medical needs. Any person, regardless of age or type and extent of the brain tumor, may receive this type of care. And it often works best when it is started right after diagnosis. People who receive palliative and supportive care along with treatment for the tumor often have less severe symptoms, better quality of life, and report that they are more satisfied with treatment.
Palliative treatments vary widely and often include medication, nutritional changes, relaxation techniques, emotional and spiritual support, and other therapies. Your child may also receive palliative treatments, such as surgery or radiation therapy, to improve symptoms.
Before treatment begins, talk with your child’s doctor about the goals of each treatment in the recommended treatment plan. You should also talk about the possible side effects of the specific treatment plan and palliative and supportive care options. Many patients also benefit from talking with a social worker and participating in support groups. Ask your doctor about these resources, too.
Medical care is often expensive, and navigating health insurance can be difficult. Ask your doctor or another member of your health care team about talking with a financial navigator or counselor who may be able to help with your financial concerns .
During treatment, your child’s health care team may ask you to answer questions about your child’s symptoms and side effects and to describe each problem. Be sure to tell the health care team if your child is experiencing a problem. This helps the health care team treat any symptoms and side effects as quickly as possible. It can also help prevent more serious problems in the future.
Learn more about the importance of tracking side effects in another part of this guide. Learn more about palliative and supportive care in a separate section of this website.
Increased hunger and obesity
Increased hunger, increased food intake, and obesity are common side effects of craniopharyngioma. The cause of increased and uncontrolled appetite for food among children with craniopharyngioma is not very well understood. However, it is believed to be related to damage to the nearby hypothalamus by the tumor or from surgery or radiation therapy. For many children with craniopharyngioma, obesity is the most severe long-term side effect of their tumor. Children with craniopharyngioma and their parents should be aware of this risk and pay special attention to eating healthy foods and getting regular exercise . It may be helpful to talk with an oncology registered dietitian and/or other health care team members.
Return to top
Remission and the chance of recurrence
After treatment, when the tumor can no longer be seen on a magnetic resonance imaging (MRI) scan, this is called having “no evidence of disease” or NED. It may also be called a remission. A remission may be temporary or permanent. This uncertainty of whether the tumor will come back causes many patients and families to feel worried or anxious. While the chance of the tumor coming back may be low, it is important to talk with your child’s doctor about the possibility of the tumor returning. This is also called a recurrence. Understanding your child’s risk of recurrence and the treatment options may help you and your family feel more prepared if the tumor does return. Learn more about coping with the fear of recurrence .
If a recurrence happens, craniopharyngioma most commonly comes back in the same place (called a local recurrence) or nearby (called a regional recurrence). When this occurs, a new cycle of testing may be done to learn as much as possible about the recurrence.
After this testing is done, your child’s doctor will talk about the treatment options. Often the treatment plan will include the treatments described above, such as surgery and/or radiation therapy, but the same type of radiation therapy cannot usually be used more than once. There are also treatments being studied in clinical trials for children with recurrent or worsening craniopharyngioma. Talk with your child's doctor about whether this might be an option for your child. Whichever treatment plan you choose, palliative and supportive care will be important for relieving symptoms and side effects.
When a tumor recurs or worsens despite treatment, patients and their families sometimes experience emotions such as disbelief or fear. You are encouraged to talk with your child's health care team about these feelings and ask about support services to help you cope. Learn more about dealing with a recurrence .
Return to top
If treatment does not work
Although treatment is successful for the majority of children with craniopharyngioma, sometimes it is not. If a child’s tumor cannot be cured or controlled, this is called an advanced or terminal tumor. This diagnosis is stressful, and advanced craniopharyngioma may be difficult to discuss. However, it is important to have open and honest conversations with your child’s health care team to express your family’s feelings, preferences, and concerns. The health care team has special skills, experience, and knowledge to support patients and their families and is there to help.
Hospice care is designed to provide the best possible quality of life for people who are expected to live less than 6 months. Parents and guardians are encouraged to talk with the health care team about hospice options, which include hospice care at home, a special hospice center, or other health care locations. Nursing care and special equipment can make staying at home a workable option for many families. Some children may be happier and more comfortable if they can 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 care planning .
The death of a child is an enormous tragedy, and families may need support to help them cope with the loss. Pediatric treatment centers often have professional staff and support groups to help with the process of grieving. Learn more on grieving the loss of a child .

The next section in this guide is About Clinical Trials . It offers more information about research studies that are focused on finding better ways to care for children with a brain tumor. Use the menu to choose a different section to read in this guide.
Craniopharyngioma - Childhood - About Clinical Trials
ON THIS PAGE: You will learn more about clinical trials, which are the main way that new medical approaches are studied to see how well they work. Use the menu to see other pages.
What are clinical trials?
Doctors and scientists are always looking for better ways to care for children with a brain tumor. To make scientific advances, doctors develop research studies involving volunteers, called clinical trials. Every drug that is now approved by the U.S. Food and Drug Administration (FDA) was tested in clinical trials.
Clinical trials are used for all types of craniopharyngioma. Many focus on new treatments to learn if a new treatment is safe, effective, and possibly better than the existing treatments. These types of studies evaluate new drugs, different combinations of treatments, new approaches to radiation therapy or surgery, and new methods of treatment.
Children who participate in clinical trials can be some of the first to get a treatment before it is available to the public. However, there are some risks with a clinical trial, including possible side effects and the chance that the new treatment may not work. People are encouraged to talk with their child’s health care team about the pros and cons of joining a specific study.
Some clinical trials study new ways to relieve symptoms and side effects during treatment. Others study ways to manage the late effects that may happen a long time after treatment. Talk with your child’s doctor about clinical trials for symptoms and side effects.
Deciding to join a clinical trial
People decide to participate in clinical trials for many reasons. Because standard treatments are not perfect, patients are often willing to face the added uncertainty of a clinical trial in the hope of a better result. Others volunteer for clinical trials because they know that these studies are a way to contribute to the progress in treating craniopharyngioma. Even if they do not benefit directly from the clinical trial, their participation may benefit future children with craniopharyngioma.
Most children with craniopharyngioma do not receive treatment in clinical trials if the surgeon can remove all of the tumor or if their age and tumor size does not limit the use of radiation therapy. Generally, clinical trials for this type of brain tumor provide treatment options when a tumor cannot be surgically removed, for those who want to delay or avoid radiation therapy, or for those with a tumor that has grown back (recurred) after surgery and/or radiation therapy.
Insurance coverage and the costs of clinical trials differ by location and by study. In some programs, some of the expenses from participating in the clinical trial are reimbursed. In others, they are not. It is important to talk with the research team and your insurance company first to learn if and how treatment in a clinical trial will be covered. Learn more about health insurance coverage of clinical trials .
Sometimes people have concerns that, in a clinical trial, their child may receive no treatment by being given a placebo or a “sugar pill.” You and your child will always be told when a placebo is used in a study. Find out more about placebos in cancer clinical trials .
Patient safety and informed consent
To join a clinical trial, parents and children must participate in a process known as informed consent. Informed consent means that parents give permission for their child to participate in a clinical trial and that teenagers give their consent to participate. During informed consent, the doctor should:
-
Describe all of the treatment options so that the person understands how the new treatment differs from the standard treatment.
-
List all of the risks of the new treatment, which may or may not be different from the risks of standard treatment.
-
Explain what will be required of each person in order to participate in the clinical trial, including the number of doctor visits, tests, and the schedule of treatment.
-
Describe the purposes of the clinical trial and what researchers are trying to learn.
Clinical trials also have certain rules called “eligibility criteria” that help structure the research and keep patients safe. You and the research team will carefully review these criteria together. You will need to meet all of the eligibility criteria in order to participate in a clinical trial. Learn more about eligibility criteria in clinical trials.
People who participate in a clinical trial may stop participating at any time for personal or medical reasons. This may include that the new treatment is not working or there are serious side effects. Clinical trials are also closely monitored by experts who watch for any problems with each study. It is important that people participating in a clinical trial talk with the doctor and researchers about who will be providing their treatment and care during the clinical trial, after the clinical trial ends, and/or if they choose to leave the clinical trial before it ends.

Craniopharyngioma - Childhood - Latest Research
ON THIS PAGE: You will read about the scientific research being done to learn more about craniopharyngioma and how to treat it. Use the menu to see other pages.
For craniopharyngioma, due to the general success of surgery and radiation therapy, current research focuses on treatments for recurrent tumors or when tumors are unable to be completely removed with surgery. There is also ongoing research to understand what allows craniopharyngioma to grow. Always talk with your child’s doctor about the best diagnostic and treatment options for your child.
-
Treatment of cysts. Sometimes, the tumor itself is not actively growing, but it has a cyst that is growing and causing symptoms. These cysts can be treated with surgery or by injections of other treatments. Such treatments include radioactive phosphorous (also known as P-32), interferon (Roferon-A, Infergen, Intron A, Alferon), and bleomycin (available as a generic drug).
-
Immunotherapy. Immunotherapy , also called biologic therapy, is designed to boost the body’s natural defenses to fight the tumor. It uses materials made either by the body or in a laboratory to improve, target, or restore immune function. Interferon is a type of immunotherapy that helps regulate the body’s natural immune system. Interferon may help treat some childhood craniopharyngiomas. It is given either as a weekly injection under the skin or by injection directly into a cyst (see above).
-
Improved methods of giving radiation therapy. For patients with a tumor that cannot be completely removed during surgery, doctors are studying new techniques for giving radiation therapy. The use of 3-dimensional radiation techniques allows high doses of radiation therapy to be delivered to the tumor with lower doses to nearby healthy brain tissue. These methods may help reduce damage to healthy tissue.
-
Proton therapy. Proton therapy is a type of external-beam radiation therapy that uses protons rather than x-rays. At high energy, protons can destroy tumor cells. Doctors are studying proton therapy for people with a tumor that cannot be completely removed with surgery. Proton therapy allows for high doses of radiation therapy to be delivered to the tumor while reducing radiation doses to the healthy brain tissue. Proton therapy is believed to be equally as effective as existing radiation therapy methods but may have fewer side effects.
-
Molecular profiling and subtyping of craniopharyngioma. Recent studies have identified 2 subtypes of craniopharyngiomas: adamantinomatous craniopharyngioma (ACP) and papillary craniopharyngioma (PCP). ACPs are typically diagnosed in children and teens 5 to 15 years old and in people 45 to 60 years old, whereas PCPs are diagnosed mainly in adults in their 50s and 60s. ACPs are most commonly cystic in appearance and are driven by mutations in the CTNNB1 gene (encoding β-catenin) that are involved in regulation and coordination of cell–cell adhesion and gene transcription. PCPs are typically solid tumors and frequently have BRAF V600E mutations. Research is currently underway to better understand the biology of these subtypes, which may lead to the development of molecular-based targeted therapy for craniopharyngiomas.
-
Palliative and supportive care . Clinical trials are underway to find better ways of reducing symptoms and side effects of current craniopharyngioma treatments to improve comfort and quality of life for patients.
-
Managing long-term side effects. There are several ongoing studies to find more effective ways to treat obesity, which is a common long-term side effect for survivors of childhood craniopharyngioma. Learn more in this guide's Follow-Up Care section.

Caring for a child with craniopharyngioma
As your child prepares to start treatment, it is normal to fear treatment-related side effects . It may help to know that your child’s health care team will work to prevent and relieve side effects. This part of treatment is called palliative and supportive care. It is an important part of your child’s treatment plan, regardless of their age or tumor size.
Coping with physical side effects
Common physical side effects from each treatment option for craniopharyngioma are described in the Types of Treatment section. Learn more about side effects of craniopharyngioma and its treatment, along with ways to prevent or control them . Changes to your child’s physical health depend on several factors, including the length and dose of treatment and your child’s general health.
It is important to discuss any new side effects or changes in existing side effects with your child’s health care team. Providing this information helps them find ways to treat or manage the side effects so your child feels more comfortable and can potentially keep any side effects from worsening.
You may find it helpful to keep track of your child’s side effects so you are prepared to discuss any changes with the health care team. Learn more about why tracking side effects is helpful .
Sometimes, side effects can last after treatment ends. Doctors call these long-term side effects. Side effects that occur months or years after treatment are called late effects . Treating long-term side effects and late effects is an important part of survivorship care. Learn more by reading the Follow-Up Care section of this guide or talking with your child’s doctor.

Coping with emotional and social effects
Your family can have emotional and social effects after a diagnosis of craniopharyngioma. This may include dealing with a variety of emotions, such as anxiety, sadness, fear, or anger, or managing stress. Sometimes, people find it difficult to express how they feel to their loved ones. Some have found that talking to an oncology social worker, counselor, or member of the clergy can help them develop more effective ways of coping and talking about a diagnosis.
You can also find coping strategies for emotional and social effects in a separate section of this website. This section includes many resources for finding support and information to meet your family's needs.

Coping with the costs of medical care
Treatment for craniopharyngioma can be expensive. It can be a source of stress and anxiety for families. In addition to treatment costs, many people find they have extra, unplanned expenses related to their child’s care. Families are encouraged to talk about financial concerns with a member of their health care team. Learn more about managing financial considerations in a separate part of this website.
Return to top
Coping with barriers to care
Some groups of people experience different rates of new tumor cases and experience different outcomes from their diseases. These differences are called “health disparities.” Disparities are caused in part by real-world barriers to quality medical care and social determinants of health , such as where a person lives and whether they have access to food and health care. Health disparities more often negatively affect racial and ethnic minorities , people with fewer financial resources , sexual and gender minorities (LGBTQ+) , adolescent and young adult populations , older adults , and people who live in rural areas or other underserved communities .
If your child is having difficulty getting the care they need, talk with a member of the health care team or explore other resources that help support medically underserved people .
Return to top
Talking with your child's health care team about side effects
Before starting treatment, talk with your child’s doctor about possible side effects. Ask:
-
Which side effects are most likely?
-
When are they likely to happen?
-
What can we do to prevent or relieve them?
-
When and who should we call about side effects?
Be sure to tell your child’s health care team about any side effects that happen during treatment and afterward, too. Tell them even if you do not think the side effects are serious. This discussion should include physical, emotional, social, and financial effects.

Caring for a child with craniopharyngioma
Family members and friends often play an important role in taking care of a child with craniopharyngioma. This is called being a caregiver. As a parent or guardian, you are the primary caregiver for your child. However, friends and family can give you valuable support, even if they live far away.
When your child has craniopharyngioma, you may have an additional range of responsibilities. These may include giving medications or managing symptoms and side effects. However, it is important to seek help from others. Below are some of the responsibilities your family or friends could help with:
-
Providing short-term care for your child
-
Giving support and encouragement
-
Assisting with meals or household chores
-
Helping with insurance and billing issues
A caregiving plan can help caregivers stay organized and help identify opportunities to delegate tasks to others. Ask how much care your child may need at home and with daily tasks during and after treatment. Use this 1-page fact sheet that includes an action plan to help make caregiving a team effort. This free fact sheet is available as a PDF, so it is easy to print.

The next section in this guide is Follow-Up Care . It explains the importance of checkups after your child's treatment is finished. Use the menu to choose a different section to read in this guide.
Craniopharyngioma - Childhood - Follow-Up Care
ON THIS PAGE: You will read about your child’s medical care after treatment is finished and why this follow-up care is important. Use the menu to see other pages.
Care for children diagnosed with craniopharyngioma does not end when active treatment has finished. Your child’s health care team will continue to check that the tumor has not come back, manage any side effects, and monitor your child’s overall health. This is called follow-up care. All children treated for craniopharyngioma should have life-long, follow-up care.
Your child’s follow-up care may include regular physical examinations, MRI scans, or both. Doctors want to keep track of your child’s recovery in the months and years ahead. Follow-up care is important to find out whether the tumor has returned, called a recurrence, or is starting to grow again.
A child treated for craniopharyngioma should have regular MRI scans to check for any growth or recurrence of the tumor. Because craniopharyngioma is slow-growing, MRI scans are often only needed once or twice a year. If your child received radiation therapy, there is a small possibility that a different type of brain tumor may develop years later.
Rehabilitation may be recommended, and this could mean any of a wide range of services such as physical therapy, occupational therapy, family or individual counseling, nutritional planning, and/or educational assistance. The goal of rehabilitation is to help survivors and their families regain control over many aspects of their lives and remain as independent as possible. Learn more about rehabilitation.
Learn more about the importance of follow-up care .
Watching for recurrence
One goal of follow-up care is to check for a recurrence, which means that the tumor has come back. A tumor recurs because small areas of tumor cells may remain undetected in the body. Over time, these cells may increase in number until they show up on test results or cause signs or symptoms.
During follow-up care, a doctor familiar with your child’s medical history can give you personalized information about the risk of recurrence. Your child's doctor will ask specific questions about your child’s health. Some children may have blood tests or imaging tests as part of regular follow-up care, but testing recommendations depend on several factors, including the type of tumor first diagnosed and the types of treatment given.
The anticipation before having a follow-up test or waiting for test results may add stress to you or a family member. This is sometimes called “scanxiety.” Learn more about how to cope with this type of stress .
Managing long-term and late side effects of a childhood brain tumor
Sometimes, side effects may linger beyond the active treatment period. These are called long-term side effects. In addition, other side effects called late effects may develop months or even years after treatment has ended. Late effects can occur almost anywhere in the body. They include physical problems, such as heart and lung problems and second cancers, which is a new cancer that happens in someone who has had another type of tumor before. They also include emotional problems, such as anxiety and depression, and problems with memory, thinking, attention, and learning.
Based on the type of treatment your child received, the doctor will recommend the examinations and tests that are needed to check for late effects. For children with craniopharyngioma, it is important to monitor their weight, visual, endocrine (hormone), and metabolic functions. As a result of the tumor and its treatment, hormone replacement (see below) is often needed.
It is also important that your child's follow-up care addresses quality of life, including any developmental or emotional concerns.
Obesity
Children who received treatment for craniopharyngioma often have problems with increased appetite, slow metabolism, weight gain, and obesity. A regular exercise program and dietary changes to the foods they eat are often recommended. Consider talking with a registered dietitian nutritionist (RD or RDN) who has experience in helping survivors manage this side effect. There are also clinical trials to help find new ways to manage weight gain for survivors of craniopharyngioma. Talk with your health care team to learn more about these resources.
Hormone replacement
A common presenting symptom and long-term side effect of children with craniopharyngiomas is diabetes insipidus. Diabetes insipidus is a result of a lack of production of a hormone called vasopressin by the pituitary gland, which is responsible for concentrating urine by the kidneys. Diabetes insipidus is treated with a hormone called desmopressin (DDAVP). Sometimes, other hormones produced by the pituitary gland are affected, too.
Hormone replacement is the use of medication to replace hormones that the body cannot produce enough of on its own. It is a type of hormone therapy . Hormone replacement is often necessary for children with craniopharyngioma because the tumor or its treatment may damage parts of the brain that make hormones, including the pituitary gland and the hypothalamus. An endocrinologist is a doctor who specializes in problems with glands and the endocrine system. This specialist will work with you and your child to determine the hormonal therapy that is needed.
The Children's Oncology Group (COG) has studied the physical and psychological effects that childhood survivors face. Based on these studies, COG has created recommendations for long-term follow-up care for childhood, adolescent, and young adult survivors that can be found on a separate website: www.survivorshipguidelines.org .
Keeping a child’s personal health record
You are encouraged to organize and keep a personal record of your child’s medical information. The doctor will help you create this. That way, as the child enters adulthood, they have a clear, written history of the diagnosis, the treatments, and the doctor’s recommendations about the schedule for follow-up care. The American Society of Clinical Oncology (ASCO) offers forms to help keep track of the treatment your child received and develop a survivorship care plan when treatment is completed.
Some children continue to see their oncologist, while others transition back to the care of their pediatrician, primary care doctor, or another health care professional. This decision depends on several factors, including the type of tumor, treatments received, side effects, health insurance rules, and your family’s personal preferences. Talk with the health care team about your child’s ongoing medical care and any concerns you have about their future health.
If a doctor who was not directly involved in your child’s care for craniopharyngioma will lead the follow-up care, be sure to share the treatment summary and survivorship care plan forms with them and with all future health care providers. Details about the specific treatment given are very valuable to the health care professionals who will care for your child throughout their lifetime.
The next section in this guide is Survivorship . It describes how to cope with challenges in everyday life after a diagnosis of craniopharyngioma. Use the menu to choose a different section to read in this guide.
Craniopharyngioma - Childhood - Survivorship
ON THIS PAGE: You will read about how to cope with challenges in everyday life after your child’s diagnosis. Use the menu to see other pages.
What is survivorship?
The word “survivorship” means different things to different people, but it often describes living with, through, and beyond being diagnosed with a tumor. In some ways, survivorship is one of the most complicated parts of the experience because it is different for every child and their family.
After active treatment ends, children and their families may experience a mixture of strong feelings, including joy, concern, relief, guilt, and fear. Some people say they appreciate life more after the diagnosis. Other families stay very anxious about their child’s health and become uncertain about coping with everyday life.
One source of stress may occur when frequent visits to the health care team end after completing treatment. Often, relationships built with the health care team provide a sense of security during treatment, and children and their families miss this source of support. This may be especially true when new worries and challenges surface over time, such as any late effects of treatment, learning or school problems, emotional challenges, sexual development and fertility concerns, and/or financial issues.
Every family faces different concerns and challenges. With any challenge, a good first step is being able to recognize each fear and talk about it. Effective coping requires:
-
Understanding the challenge your family is facing
-
Thinking through solutions
-
Asking for and allowing the support of others
-
Feeling comfortable with the course of action your family chooses
It may be helpful to join an in-person support group or online community of childhood brain tumor survivors. Support groups also exist for parents of children diagnosed with this type of tumor. This allows you to talk with people who have had similar first-hand experiences. Other options for finding support include talking with a friend or member of the health care team, individual counseling, or asking for assistance at the learning resource center of the place where your child received treatment.
Healthy living after craniopharyngioma
Survivorship often serves as a strong motivator to make lifestyle changes, often for the whole family.
Children who have had a tumor can enhance the quality of their future by following established guidelines for good health into and through adulthood, including not smoking, limiting alcohol, maintaining a healthy weight, eating well, managing stress, and participating in regular physical activity. Talk with the doctor about developing a plan that is best for your child. Learn more about making healthy lifestyle choices .
It is important that your child has recommended medical checkups and tests (see Follow-Up Care ) to take care of their health. Ask the doctor about receiving a survivorship care plan that is best for your child’s needs.
Changing role of caregivers
Parents, other family members, and friends may also go through periods of transition. A caregiver plays a very important role in supporting a child diagnosed with craniopharyngioma, providing physical, emotional, and practical care on a daily or as-needed basis. Many caregivers become focused on providing this support, especially if the treatment period lasts for many months or longer.
However, as treatment is completed, the caregiver's role often changes. Eventually, the need for caregiving related to a child’s diagnosis will become much less or come to an end as your child gets older. Family counselors at pediatric treatment centers can help with this transition. You can also learn more about adjusting to life after caregiving .
