Childhood Ependymoma Treatment (PDQ®)

Treatment of Newly Diagnosed Childhood Myxopapillary Ependymoma

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.[1,2]

Standard treatment options for newly diagnosed myxopapillary ependymoma (WHO Grade I) include the following:

  1. Surgery with or without adjuvant radiation therapy.

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.[3]; [4][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.[1,3]; [5][Level of evidence: 3iiiDi]; [6,7][Level of evidence: 3iiiDiii]
