上衣腫の小児患者の治療における LET 最適化 IMPT
上衣腫の小児患者に対する LET 最適化 IMPT のパイロット試験
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.

状態
詳細な説明
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 effectiveness (RBE) models and enhance their precision based on prospectively collected clinical image biomarkers.
IV. To evaluate acute and late toxicities, including pseudoprogression and symptom burden, in patients treated with bio-IMPT.
V. To estimate progression-free survival (PFS) and overall survival (OS). VI. To evaluate disease outcomes following the use of a simultaneous integrated boost (SIB) for pediatric ependymoma patients with gross residual disease following surgery.
OUTLINE:
Patients receive LET optimized IMPT for up to 6 weeks.
After completion of study treatment, patients are followed up at 1 month, then every 3 months for up to 24 months.

Incidence of adverse events
時間枠:Up to 6 months post treatment
|
The safety of linear energy transfer-optimized intensity modulated proton therapy will be defined by treatment failures which include imaging changes consistent with necrosis in the presence of Common Terminology Criteria for Adverse Events version 4.03 symptoms of grade 3 brain necrosis and/or local recurrence within the first 6 months from the end of proton therapy. |
Up to 6 months post treatment
