Summary

This trial studies the side effects of a new type of radiation therapy called LET optimized image modulated proton therapy in treating pediatric patients with ependymoma.

Who is the study for?
This trial is for children with a brain tumor called ependymoma, confirmed by previous tests. They should be able to perform daily activities at least half the time (Lansky score 50-100), have no tumor spread in the spine or previous brain radiation, and not be pregnant. They must also be able to undergo MRI scans and handle gadolinium contrast.
What is being tested?
The study is testing LET Optimized IMPT, a type of precise radiation therapy that targets tumors while sparing healthy tissue. It's for kids who haven't had prior radiation and aren't on chemo during the trial. The effects on quality of life will also be assessed through questionnaires.
What are the potential side effects?
Potential side effects include skin reactions near treatment areas, fatigue, headaches, hair loss at the irradiated site, nausea or vomiting. Long-term risks may involve growth development issues due to exposure of healthy tissues to radiation.
