Study Description

Brief Summary: This trial gathers information from patients with primary central nervous system or base of skull tumors that receive proton beam therapy and see if certain imaging techniques can help detect radiation-related changes over time. This study may help providers learn more about proton beam radiotherapy and how to improve the way it is delivered.

Detailed Description: PRIMARY OBJECTIVE: I. To establish linear energy transfer (LET)-based models as early predictors for white matter changes on magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) sequences in pediatric patients following proton beam therapy for primary central nervous system (CNS) and base of skull tumors. OUTLINE: Patients' medical charts are reviewed.
