Grade I and II Ependymal Tumors

Ependymomas (World Health Organization [WHO] grade II) and WHO grade I ependymal tumors, i.e., subependymoma and myxopapillary ependymomas, are often curable. (Refer to the Ependymal Tumors section in the Classification section of this summary for more information.)

Standard treatment options:

1. Surgery alone if the tumor is totally resectable.
2. Surgery followed by radiation therapy to known or suspected residual tumor.[1,2]

Treatment options under clinical evaluation:

• At recurrence following surgery, patients should be considered for reoperation and radiation therapy if not previously given. Patients who have received radiation therapy should be considered candidates for nitrosourea-based chemotherapies and for clinical trials that evaluate new drugs and biological response modifiers.

Anaplastic ependymomas (WHO grade III) have variable prognoses that depend on the location and extent of disease. Frequently, but not invariably, anaplastic ependymomas have worse prognoses than lower grade ependymal tumors. (Refer to the Anaplastic Ependymoma section in the Classification section of this summary for more information.)

Standard treatment options:

• Surgery plus radiation therapy.[1-3]

Treatment options under clinical evaluation:

• Adjuvant chemotherapy before, during, and after radiation are treatment options being evaluated. At recurrence, patients should be considered candidates for nitrosourea-based chemotherapies and for clinical trials that evaluate new drugs and biological response modifiers.

Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with adult ependymal tumors. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

General information about clinical trials is also available from the NCI Web site.
