About Ependymoma

What is it?

Ependymoma is a rare type of primary brain or spinal cord tumor. Primary brain and spinal cord tumors are a type of tumor that starts in the central nervous system (CNS).

These tumors are classified according to the presumed cell of origin. The most common types of cells in the nervous system are neurons and glial cells, although tumors from neurons are rare.

How do ependymomas form? Do they spread?

Ependymomas are a rare type of glioma that are thought to develop from the ependymal cells that line the ventricles (fluid-filled spaces in the brain) and the central canal of the spinal cord. Ependymomas can occur anywhere in the CNS, including the brain or the spinal cord. Occasionally, ependymoma tumor cells can spread in the cerebrospinal fluid (CSF) and involve multiple areas. Although it is very rare for ependymoma to spread to other parts of the body, the development of tumor cells into the CSF often results in tumors developing in other areas of the CNS. Typically, tumor nodules form where the tumor cells settle such as the base of the brain and the bottom of the spinal cord.

Who does ependymoma effect?

Ependymomas represent three to six percent of all CNS tumors. They can occur in both children and adults.

How often do ependymomas form in children?

The incidence of ependymomas is higher in children than in adults. Ependymomas are the third most common form of pediatric brain tumors of the CNS, and the majority of these tumors occur in young patients’ brains. Specifically, these tumors are most commonly found in the posterior fossa.

How often do ependymomas form in adults?

For adults, ependymomas account for five percent of adult gliomas with the majority occurring in the spine.

Currently, the Surveillance Epidemiology and the End Results (SEER) Programe and the Central Brain Tumor Registry (CBTRUS) group all grades of ependymomas together for reporting purposes.

According to a CBTRUS report on incidence rates between 1998 and 2002, 1,126 ependymomas and anaplastic ependymomas were diagnosed for an adjusted rate per 100,000 person-years of 0.26. This rate is slightly higher in males (0.29) than females (0.22), and in whites (0.27) versus blacks (0.12).

      So sorry to hear of your Ethan’s diagnosis. I’m glad you found us – we believe in the power of positive thinking and we certainly look for stories of hope too! There are so many sad stories, and sometimes it seems overwhelming, but we have also heard of many amazing kids who are doing well.
      Have you joined the Ependyparents Facebook group? While it can be a bit difficult to take in at first, there are a great community of other parents on there who are happy to offer love, support and advice any time of the day or night. Sometimes it’s tough to read the sad posts, but so many kids are doing well too it’s wonderful to follow their journeys.
      We also have a Facebook page where we post updates regularly – Ethan Davies Scholarship for Brain Cancer Research.
      Wishing you and your Ethan all the best,
      Christie-Lee Davies
