Pilot Trial of LET Optimized IMPT for Pediatric Patients With Ependymoma
This phase I trial studies the side effects of linear energy transfer (LET) optimized image modulated proton therapy (IMPT) in treating pediatric patients with ependymoma. Radiation therapy such as LET optimized IMPT, uses proton beams to kill tumor cells and shrink tumors without damaging surrounding normal tissues.
• Previous pathologic confirmation of ependymoma, World Health Organization (WHO) grade II or III
• Disease must be confined to the brain (no evidence of spread on MR imaging of the spine or on staging lumbar puncture)
• Patient may not receive chemotherapy concurrent with radiation
• Signed informed consent by patient and/or parents or legal guardian
• Lansky performance status score of 50 -100
