NCT02125786

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

Other Outcomes (7)

  • Avidity of Ependymoma to 18F-fluorodeoxyglucose and 11C-methionine PET Prior to Radiation Therapy

    Baseline

  • Longitudinal Change of Avidity of Ependymoma to 18F-fluorodeoxyglucose and 11C-methionine PET Prior to Radiation Therapy

    12, 24 and 36 months after second course of irradiation

  • Longitudinal Change of Necrosis Measured With MET/FDG and Necrosis Measured With MRI

    Baseline, and at 12, 24 and 36 month

  • +4 more other outcomes

Study Arms (4)

Stratum 1: Local Failure

EXPERIMENTAL

Participants 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

EXPERIMENTAL

Participants 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

EXPERIMENTAL

Participants 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

EXPERIMENTAL

Local 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.

Interventions

SurgeryPROCEDURE

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.

Also known as: Metastasectomy
Stratum 1: Local FailureStratum 2: Metastatic FailureStratum 3: Local and Metastatic FailureStratum 4: Local Failure
IrradiationRADIATION

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.

Also known as: Focal irradiation, Craniospinal irradiation
