Brief Summary
The primary purpose of this study is to investigate whether surgery and re-irradiation will help treat ependymoma that has come back after initial treatment. The combined doses of the first and second courses of radiation are higher than what is usual standard of care. The investigators will study the effects and side effects of surgery and re-irradiation. They will also evaluate and study tumor tissue and blood to learn more about the tumor and how it does or does not respond to treatments and will use magnetic resonance imaging (MRI) and positron emission tomography (PET) scans to see if they can predict tumor response and tumor recurrence. Participants will be followed for up to 5 years following enrollment. Evaluations during radiation therapy will be done weekly while receiving therapy for up to 7 weeks. Other evaluations will be done at enrollment, every 4 months from enrollment through 3 years, and every 6 months during the 4th and 5th year.

Outcome Measures
Primary Outcomes (2)
3-year Progression-free Survival Rate
To prospectively estimate the progression-free distribution for children and young adults with recurrent ependymoma treated with a second course of irradiation.
2 years follow-up after initiation of radiation therapy for the last patient enrolled
3-year Overall Survival Rate
OS was calculated from the date of initial radiation therapy to date of death or date of last contact for the patients who were treated with RT. The event of interest was death.
2 years follow-up after initiation of radiation therapy for the last patient enrolled
Secondary Outcomes (24)
Incidence Rate of Neurological Deficits
Through 5 years after initiation of second course of irradiation
Incidence Rate of Ophthalmological Deficits
Through 5 years after initiation of second course of irradiation
Incidence Rate of Audiological Deficits
Through 5 years after initiation of second course of irradiation
Incidence Rate of Endocrine Deficits
Through 5 years after initiation of second course of irradiation
Number of Neurocognitive Deficits
Through 5 years after initiation of second course of irradiation
- +19 more secondary outcomes

Study Arms (4)
Stratum 1: Local Failure
EXPERIMENTALParticipants exhibit an initial pattern of failure that is local (disease confined to primary site). Treatment is surgery and a second course of focal irradiation. The total dose for the second course of irradiation will be 54Gy. Participants may receive one or both: Photon therapy or proton therapy. Participants receive \^1\^8F-fluorodeoxyglucose and \^1\^1C-methionine to aid in tumor visualization.
Stratum 2: Metastatic Failure
EXPERIMENTALParticipants exhibit an initial pattern of failure that is metastatic (neuraxis metastatic disease without equivocal evidence of local failure). Treatment is surgery and craniospinal irradiation. Craniospinal irradiation (36-39.6Gy) will include focal boost treatment of metastatic sites (54-59.4Gy) depending on location, extent of resection and target volume. Participants may receive one or both: Photon therapy or proton therapy. Participants receive \^1\^8F-fluorodeoxyglucose and \^1\^1C-methionine to aid in tumor visualization.
Stratum 3: Local and Metastatic Failure
EXPERIMENTALParticipants exhibit an initial pattern of failure that is both local and metastatic (neuraxis metastatic disease with equivocal evidence of local failure). Treatment is surgery and craniospinal irradiation. Participants may receive one or both: Photon therapy or proton therapy. Participants receive \^1\^8F-fluorodeoxyglucose and \^1\^1C-methionine to aid in tumor visualization.
Stratum 4: Local Failure
EXPERIMENTALLocal Failure Participants exhibit an initial pattern of failure that is local (disease confined to primary site). Age is \>36 months at time of enrollment to \<21 years. Tumor shows presence of 1q gain. Treatment is optional craniospinal irradiation. Participants may receive one or both: Photon therapy or proton therapy. Participants receive \^1\^8F-fluorodeoxyglucose and \^1\^1C-methionine to aid in tumor visualization.
Interventions
When applicable, surgery will be used to remove metastases. The goal of surgery is to achieve gross total resection of all imaging visible residual tumor.
Radiation therapy on this protocol will be based on extent of disease, extent of resection and location. The allowed treatment modalities include conformal or intensity-modulated radiation therapy using photons or proton therapy using double-scattering or spot-scanning methods. The general goal is to initiate radiation therapy within 12 weeks of last surgery performed at the time of recurrence.
This is a contrast media that will be given intravenously to aid in tumor visualization.

Eligibility Criteria
You may qualify if:
- Progressive intracranial ependymoma after prior focal irradiation
- Patients aged 1-21 years at the time of enrollment
- Adequate performance status (ECOG \< 3) and research participant does not require mechanical ventilation
- Interval from start of initial radiation therapy to enrollment \> 9 months
You may not qualify if:
- Prior craniospinal irradiation
- Pregnant women are excluded from enrollment on this study because radiation therapy is an agent with the potential for teratogenic or abortifacient effects
- Any patient with both metastatic ependymoma and age \< 3 years at the time of enrollment
