What was measured

EFS between centrally reviewed differentiated ependymoma and anaplastic ependymoma for the patients who were treated with radiation therapy only. The event-free survival (EFS) defined as the time to disease progression, disease relapse, occurrence of a second neoplasm, or death from any cause, measured from the start of radiation therapy. The product-limit (Kaplan-Meier) estimate is for estimation of EFS probability at 5 years.

Analysis population: Supratentorial Anaplastic Ependymoma (GTR1, GTR2, NTR) and Anaplastic or Differentiated Infratentorial Ependymoma (GTR1, GTR2, NTR) and Supratentorial Differentiated Ependymoma(GTR2, NTR). Patients undergo conformal radiation therapy to the brain once daily 5 days a week for 6-6½ weeks.
