Childhood Central Nervous System Embryonal Tumors Treatment (PDQ®)

Treatment of Newly Diagnosed Medulloepithelioma and Ependymoblastoma

There are few data on which to base treatment of newly diagnosed medulloepithelioma and ependymoblastoma tumors. Treatment considerations are usually the same as those for children with high-risk medulloblastoma and for children aged 3 years and younger at diagnosis with other embryonal tumors. (Refer to the Children Older Than 3 Years with High-Risk Medulloblastoma and medulloblastoma Children Aged 3 Years and Younger sections of this summary for more information.)

Prognosis is poor, with 5-year survival rates ranging between 0% and 30%.[1-4]

Current Clinical Trials

Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with childhood ependymoblastoma and childhood medulloepithelioma. 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.
