What was measured
Overall survival (OS) is measured from the date of study enrollment to the date to death. The product-limit (Kaplan-Meier) estimate is for estimation of OS probability at 5 years.
Analysis population: All eligible patients in the study were included. The product-limit (Kaplan-Meier) estimate is for estimation of OS probability.
Groups in this outcome
GTR1 Differentiated Histology Supratentorial (Group 1)
Patients undergo observation.
Radiation (Group 2)
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. radiation therapy: Given once daily 5 days a week for 6-6½ weeks
Sub-Total Resection Any Histology or Location (STR) (Group 3)
Patients receive initial course of chemotherapy comprising vincristine sulfate IV on days 1 and 8, carboplatin IV over 1 hour on day 1, and cyclophosphamide IV over 1 hour on days 1 and 2. Patients also receive filgrastim (G-CSF) subcutaneously or IV beginning on day 3 and continuing until blood counts recover. Patients then receive a second course of chemotherapy comprising vincristine sulfate IV on days 1 and 8, carboplatin IV over 1 hour on day 1, and oral etoposide on days 1-21. After completion of chemotherapy, patients are evaluated for second therapeutic conventional surgery. Patients who have unresectable disease undergo conformal radiation therapy. Patients who have resectable disease undergo second surgery followed by conformal radiotherapy. filgrastim: Given IV or SC (5mcg/kg/day) start on Day 3 and continue until ANC \>1500/μl given subcutaneously or intravenously. carboplatin: Given IV (375 mg/m2/day) Day 1 given as an IV infusion over one hour.
