Ependymoma is a type of brain tumor that may arise in the ventricles of the brain or in the spinal cord. It is also called an ependymal tumor. Learn about ependymoma and find information on how we support and care for children and teens with ependymoma before, during, and after treatment.
The Brain Tumor Center at Dana-Farber/Boston Children's Cancer and Blood Disorders Center cares for children with many different types of common and rare brain and spinal tumors, including astrocytomas, medulloblastomas, ependymoma, glioblastomas, and primitive neuroectodermal tumors (PNET).
Your child will receive care from some of the world’s most experienced pediatric brain tumor doctors and internationally recognized pediatric subspecialists.
Our team works closely together to develop a care plan that offers your child the highest possible quality of life after treatment, and takes the needs of your child and your family into account.
Children treated at the Brain Tumor Center have access to some of the most advanced diagnostics and therapies, including:
Thanks to refined surgical techniques and improved chemotherapy and radiation therapy, the majority of children with brain and spinal cord tumors are now long-term survivors. However, they may face physical, social, and intellectual challenges that require specialized care.

An ependymoma is a tumor that arises in the cells lining the ventricular system of the brain or spinal cord. The ventricles contain cerebrospinal fluid (CSF). Ependymomas can form in any of the ventricles in the brain or spinal cord, but most ependymomas arise in the fourth ventricle and affect the cerebellum and the brain stem.
Ependymomas account for 5 to 10 percent of pediatric brain tumors and occur equally in boys and girls. These types of tumors are the third most common brain tumor in children. Though ependymomas rarely occur in the spinal cord, they do account for about 25 percent of all spinal cord tumors. Most patients with tumors of the spinal cord are older than 12.
Children with ependymomas are treated at Dana-Farber/Boston Children's through the Brain Tumor Center, a world-renowned destination for children with malignant and non-malignant brain and spinal cord tumors. Our brain tumor specialists have extensive expertise in treating all types of brain tumors, including ependymomas.

The PDQ childhood brain tumor treatment summaries are organized primarily according to the World Health Organization (WHO) classification of nervous system tumors. For a full description of the classification of nervous system tumors and a link to the corresponding treatment summary for each type of brain tumor, refer to the PDQ summary on Childhood Brain and Spinal Cord Tumors Treatment Overview.
Dramatic improvements in survival have been achieved for children and adolescents with cancer. Between 1975 and 2010, childhood cancer mortality decreased by more than 50%. Childhood and adolescent cancer survivors require close follow-up because cancer therapy side effects may persist or develop months or years after treatment. (Refer to the PDQ summary Late Effects of Treatment for Childhood Cancer for specific information about the incidence, type, and monitoring of late effects in childhood and adolescent cancer survivors.)
Primary brain tumors are a diverse group of diseases that together constitute the most common solid tumor of childhood. Immunohistochemical analysis, cytogenetic and molecular genetic findings, and measures of mitotic activity are increasingly used in tumor diagnosis and classification. Brain tumors are classified according to histology, but tumor location and extent of spread are important factors that affect treatment and prognosis.
Ependymomas arise from ependymal cells that line the ventricles and passageways in the brain and the center of the spinal cord. Ependymal cells produce cerebrospinal fluid (CSF). These tumors are classified as supratentorial or infratentorial. In children, most ependymomas are infratentorial tumors that arise in or around the fourth ventricle. According to the WHO classification of brain tumors, ependymal tumors are classified into the following four main subtypes:
The location of the tumor determines the clinical presentation. Treatment begins with surgery. The type of adjuvant therapy given, such as a second surgery, chemotherapy, or radiation therapy, depends on the following:
Childhood ependymoma comprises approximately 9% of all childhood brain tumors, representing about 200 cases per year in the United States.
The clinical presentation of ependymoma is dependent on tumor location.
Every patient suspected of having ependymoma should be
evaluated with diagnostic imaging of the whole brain and spinal cord. The most
sensitive method available for evaluating spinal cord subarachnoid metastasis
is spinal magnetic resonance imaging (MRI) performed with gadolinium. This is ideally done before surgery to avoid confusion with postoperative blood. If MRI
is used, the entire spine is generally imaged in at least two planes with contiguous
MRI slices performed after gadolinium enhancement. If feasible, CSF cytological evaluation should be conducted.
Unfavorable factors affecting outcome (except as noted) include the following:
Posterior fossa ependymoma can be divided into the following two groups based on distinctive patterns of gene expression.
Other factors that have been reported to be associated with poor prognosis for pediatric ependymoma include expression of the enzymatic subunit of telomerase (hTERT)  and expression of the neural stem cell marker Nestin.[Level of evidence: 3iiiA]
Surveillance neuroimaging, coupled with clinical assessments, are generally recommended after treatment for ependymoma. The frequency and duration have been arbitrarily determined and the utility is uncertain. Most practitioners obtain MRI imaging of the brain and/or spinal cord every 3 months for the first 1 to 2 years after treatment. After 2 years, imaging every 6 months for the next 3 years is often undertaken.

In the most recent World Health Organization (WHO) classification of brain tumors, ependymal tumors are classified into the following four main subtypes:
The true incidence of subependymomas (WHO Grade I) is difficult to determine. These tumors are frequently asymptomatic and may be found incidentally at autopsy. Subependymomas probably comprise less than 5% of all ependymal tumors.
In children, approximately 65% to 75% of ependymomas arise in the posterior fossa. Although supratentorial and infratentorial ependymomas are believed to arise from radial glia cells, they have different genomic, gene expression, and immunohistochemical signatures. Supratentorial tumors are more often characterized by neuronal differentiation.
Subependymomas and myxopapillary ependymomas are usually considered to be clinically and pathologically distinct from the Grade II and Grade III ependymomas. In Grade II and Grade III ependymomas, the relationship between histological features and survival has varied among studies, although most recent larger studies and meta-analyses have demonstrated that histological grade is an independent predictor of event-free survival. A single-institution study suggests that patients with clear-cell ependymomas may have a higher risk of treatment failure than do patients with other forms of WHO Grade II ependymomas; however, confirmation is required in a larger group of unselected patients.
Ependymoblastomas, which generally
behave more like medulloblastomas or cerebral neuroectodermal tumors, are
considered separate entities from ependymomas and are now classified with the embryonal tumors. (Refer to the PDQ summary on Childhood Central Nervous System Embryonal Tumors Treatment for more information.)
classification of pediatric brain tumors is a specialized area that is
evolving; review of the diagnostic tissue by a neuropathologist who
has particular expertise in this area is strongly recommended.

Although there is no formal staging system, ependymomas can be divided into
supratentorial, infratentorial, and spinal tumors. Approximately 30% of childhood ependymomas arise in supratentorial regions of the brain and 70% arise in the posterior fossa. They usually originate in the
ependymal linings of ventricles or central canal or ventriculus terminalis of the spinal cord and have access to the cerebrospinal fluid. Therefore, these tumors may
spread throughout the neuraxis, although dissemination is noted in less than 10% of patients with Grade II and Grade III ependymomas. Myxopapillary ependymomas are more likely to disseminate to the nervous system early in the course of illness.

Many of the improvements in survival in childhood cancer have been made as a
result of clinical trials that have attempted to improve on the best available,
accepted therapy. Clinical trials in pediatrics are designed to compare new
therapy with therapy that is currently accepted as standard. This comparison
may be done in a randomized study of two treatment arms or by evaluating a single
new treatment and comparing the results with those previously obtained with
Because of the relative rarity of cancer in children, all patients with aggressive brain
tumors should be considered for entry into a clinical trial. To determine and
implement optimum treatment, treatment planning by a multidisciplinary team of
cancer specialists who have experience treating childhood brain tumors is
required. Radiation therapy of pediatric brain tumors is technically demanding and should be performed in centers that have experience in that
area to ensure optimal results.

The standard treatment options for newly diagnosed subependymoma (WHO Grade I) include the following:
In cases requiring therapy, complete surgical removal is often curative. Some subependymomas are considered incidental findings and observed without intervention.
Occasionally, subependymomas cause ventricular obstruction and, in these cases, ventriculoperitoneal shunt placement is indicated. Spontaneous intratumoral hemorrhage has also been observed.

Myxopapillary ependymomas, considered to be a histologic subtype of ependymoma, have a relatively high incidence of central nervous system tumor dissemination at diagnosis and at follow-up. Imaging of the complete craniospinal axis at the time of diagnosis and during follow-up is indicated.
Standard treatment options for newly diagnosed myxopapillary ependymoma (WHO Grade I) include the following:
Historically, the management of myxopapillary ependymoma (WHO Grade I) consisted of an attempt at en bloc resection of the tumor with no further treatment in the case of a gross-total resection.; [Level of evidence: 3iiiDi] However, based on the finding that dissemination of these tumors to other parts of the neuraxis can occur, particularly when complete resection is not obtained, and evidence that focal radiation therapy may improve progression-free survival, many practitioners now favor the use of radiation therapy after surgical resection of the primary mass.; [Level of evidence: 3iiiDi]; [Level of evidence: 3iiiDiii]

Standard treatment options for newly diagnosed ependymoma (WHO Grade II) or anaplastic ependymoma (WHO Grade III) include the following:
Typically, all patients undergo surgery to remove the tumor. Whether additional treatment is given depends on the extent of tumor resection and whether there is disseminated disease.
Surgery should be
performed in an attempt at maximal tumor reduction. Evidence suggests that more extensive surgical resection is related to an improved rate of survival.; [Level of evidence: 3iDii] Magnetic resonance imaging (MRI) should be performed postoperatively to confirm the extent of resection. If not performed preoperatively, MRI of the entire neuraxis to evaluate disease dissemination and cerebrospinal fluid cytopathology should be performed.
Patients with residual tumor or disseminated
disease should be considered at high risk for relapse and should be treated on
protocols specifically designed for them. Those with no evidence of residual
tumor still have an approximate 20% to 40% relapse risk in spite of
postoperative radiation therapy.
Anecdotal experience suggests that surgery alone for completely resected supratentorial nonanaplastic tumors and intradural spinal cord ependymomas may, in select cases, be an appropriate approach to treatment.[Level of evidence: 3iiiDi]; [Level of evidence: 3iiiDiii]
The traditional postsurgical treatment for these patients has been radiation
therapy consisting of 54 Gy to 55.8 Gy to the tumor bed for children aged 3 years and older. It is not necessary
to treat the entire CNS (whole brain and spine) because these tumors usually
recur initially at the local site.; [Level of evidence: 3iiiA] When possible, patients should be treated in a
center experienced with the delivery of highly conformal radiation therapy (including intensity-modulated radiation therapy or charged-particle radiation therapy) to pediatric patients with brain tumors.
Evidence (radiation therapy):
Focal radiation therapy has been used in certain cases. In a small series of children with localized ependymoma, surgery alone was compared with adjuvant radiation therapy. Adjuvant radiation therapy appeared to improve PFS, even after adjusting for the extent of resection. In fact, a PFS benefit was observed for patients who received adjuvant radiation therapy after gross-total resection, compared with those who did not receive radiation therapy. Additional research will be necessary to confirm these findings.
Proton-beam radiation therapy (a type of charged-particle radiation therapy) provides a possible advantage for targeting the tumor while avoiding critical normal brain and neuroendocrine tissues, whether the tumor is supratentorial or infratentorial. Seventy children treated with involved-field, proton-beam radiation at Massachusetts General Hospital between 2000 and 2011 (median age, 33 months; range, 3 months–20 years) had 3-year local control of 83%, PFS of 76%, and overall survival (OS) of 95%, with confirmation that subtotal resection was associated with an inferior outcome. Data demonstrating an advantage in terms of intelligence, adaptive skills, neuroendocrine deficiencies, and other morbidities do not yet show an advantage over other forms of conformal radiation therapy.
There is no evidence to date that adjuvant
chemotherapy, including the use of myeloablative chemotherapy, improves the outcome for patients with totally resected, nondisseminated ependymoma. For this reason, current treatment approaches do not include chemotherapy as a standard component of primary therapy for children with newly diagnosed ependymomas that are completely resected.
A randomized trial evaluating the efficacy of postradiation chemotherapy in children who have had a gross-total resection is underway.
Second-look surgery should be considered because patients who have complete
resections have better disease control. In some cases, further surgery can be undertaken after the initial attempted resection if the pediatric neurosurgeon believes that a gross-total resection could be obtained by an alternate surgical approach to the tumor. In other cases, further up-front surgery is not anticipated to result in a gross-total resection, therefore, adjuvant therapy is initiated with future consideration of second-look surgery.
The rationale for radiation therapy as described in the Treatment options for no residual disease, no disseminated disease subsection above also pertains to the treatment of children with residual, nondisseminated ependymoma. In patients with a subtotal resection, treatment with radiation therapy results in 3-year to 5-year PFS in 30% to 50% of patients, although the outcome for patients with residual tumor within the spinal canal may be better.
One study demonstrated a benefit of preirradiation chemotherapy in children with near-total resection (>90% resection), with outcomes comparable to children achieving a gross-total resection followed by radiation therapy. The Children’s Oncology Group (COG) has completed a study of preirradiation chemotherapy in children with residual disease after up-front surgery to determine whether children treated with chemotherapy can achieve a complete response with chemotherapy or second-look surgery. Results are pending.
There is no evidence that high-dose chemotherapy with stem cell rescue is of any benefit.; [Level of evidence: 2A]
Regardless of the degree of surgical
resection, these patients generally receive radiation therapy to the whole
brain and spine, along with boosts to local disease and bulk areas of
disseminated disease. The traditional local postsurgical radiation doses in
these patients have been 54 Gy to 55.8 Gy. Doses of approximately 36 Gy to
the entire neuraxis (i.e., the whole brain and spine) are also
administered but may be modulated depending on the age of the patient. Boosts
between 41.4 Gy and 50.4 Gy to bulk areas of spinal disease are
administered, with doses depending on the age of the patient and the location
of the tumor. However, there are no contemporary studies published to support this approach.
The role of chemotherapy in the management of children with disseminated ependymoma is unproven.
Children younger than 3 years are
particularly susceptible to the adverse effects of radiation on brain
development.[Level of evidence: 3iiiC] Debilitating effects on growth and neurologic development have
frequently been observed, especially in younger children. Consequently, radiation therapy immediately after surgery in children younger than 3 years
has historically been limited, with attempts to delay its administration through the use of chemotherapy.; [Level of evidence: 2A]
Some, but not all, chemotherapy regimens induce objective responses in children younger than 3 years with newly diagnosed ependymoma. Up to 40% of infants and young children with totally resected disease may achieve long-term survival with chemotherapy alone.[Level of evidence: 2Di]
Because of the known effects of radiation on growth and neurocognitive
development, the use of radiation therapy in children younger than 3 years has been limited.
Conformal radiation approaches, such as 3-dimensional conformal radiation therapy, that minimize damage to normal brain tissue and charged-particle radiation therapy, such as proton-beam therapy, are under evaluation for infants and children with ependymoma. When analyzing neurologic outcome after treatment of young children with ependymoma, it is important to consider that not all long-term deficits can be ascribed to radiation therapy because deficits may be present in young children before therapy begins. For example, the presence of hydrocephalus at diagnosis is associated with lower intelligence quotient as measured after surgical resection and before administration of radiation therapy.
The recently completed COG protocol (ACNS0121 [NCT00027846]) for children with ependymoma includes children aged 1 year and older. The trial is a prospective evaluation of postoperative radiation therapy. Results are forthcoming.
The following is an example of a national and/or institutional clinical trial that is currently being conducted or is under analysis. Information about ongoing clinical trials is available from the NCI Web site.
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with newly diagnosed childhood ependymoma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

Recurrence is not uncommon for all grades of ependymoma
and may develop many years after initial treatment. Late recurrence
beyond 10 to 15 years has been reported. Disease generally recurs at the
primary tumor site, although concomitant neuraxis dissemination may also be seen. Systemic
relapse is extremely rare. At time of relapse, a complete evaluation for
extent of recurrence is indicated for all patients.
The need for further surgical
intervention is individualized based on the following:
In some cases, surgically accessible lesions may be treated alternatively by radiation therapy.
Patients with recurrent ependymomas who have
not previously received radiation therapy and/or chemotherapy should be
considered for treatment with the following modalities:[Level of evidence: 3iiiB]
Regardless of treatment strategy, the prognosis for patients with recurrence is poor. Entry into
studies of novel therapeutic approaches should be considered.
Early-phase therapeutic trials may be available for selected patients. These trials may be available via Children's Oncology Group, the Pediatric Brain Tumor Consortium, or other entities. Information about ongoing clinical trials is available from the NCI Web site.
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with recurrent childhood ependymoma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
