Pilot Trial of LET Optimized IMPT for Pediatric Patients With Ependymoma
M.D. Anderson Cancer Center
Summary
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.
Description
PRIMARY OBJECTIVES: I. To evaluate the safety of linear energy transfer (LET) optimized image modulated proton therapy (IMPT) (bio-IMPT) for pediatric patients with ependymoma. SECONDARY OBJECTIVES: I. To utilize advanced multiparametric magnetic resonance (MR) imaging to identify imaging biomarkers of structural and biological changes after proton therapy in pediatric ependymoma patients. II. To compare quantitative image biomarkers in patients treated with bio-IMPT and standard proton therapy using a voxel level analysis. III. To test and evaluate the validity of relative biological eff…
