Registered outcomes6

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryEvent-free SurvivalUp to 5 years after completion of study treatment
Event-free survival is calculated from the date of study enrollment to the date of disease progression, disease relapse, occurrence of second neoplasm, or death from any cause. The product-limit (Kaplan-Meier) estimate is for estimation of Event -free survival (EFS) probability at 5 years.
SecondaryOverall SurvivalUp to 5 years after completion of study treatmentOverall 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.
SecondaryRate of Gross-total or Near-total Resection and Second Surgery After ChemotherapyAt the time of second surgeryThe Rate Of Gross-Total or Near-Total Resection With Second Surgery After Chemotherapy Treatment.
SecondaryEvent-free Survival (EFS)At 5 years since the time of radiation therapy.
EFS between centrally reviewed differentiated ependymoma and anaplastic ependymoma for the patients who had sub-total resection initially. The event-free survival (EFS) defined as the date of disease progression, disease relapse, occurrence of a second neoplasm, or death from any cause, measured from the start date of radiation therapy. The product-limit (Kaplan-Meier) estimate is for estimation of EFS probability.
SecondaryEvent-free Survival (EFS)At 5 years since the time of radiation therapy
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.
SecondaryLocal Control and Patterns of FailureUp to 5 years after completion of study treatmentDocumented and analyzed qualitatively and quantitatively.

SECONDARYEvent-free Survival (EFS)At 5 years since the time of radiation therapy.
Of 64 eligible patients who had initial subtotal resection, 5 patients were off-therapy prior to radiation therapy, and 4 patients had a disease progression prior to radiation therapy. There were 55 eligible patients included in the analysis. The product-limit (Kaplan-Meier) estimate is for estimation of EFS probability.
