Investigating brain network changes in children with brain tumors after radiation therapy

Assessing Radiation Induced Alterations in Resting State Brain Networks in Pediatric Brain Tumor Patients

Observational Washington University School of Medicine · NCT06185686

This study is trying to see how radiation therapy changes brain connections in children with brain tumors and how those changes might affect their thinking skills after treatment.

What this trial studies

This observational study aims to explore how radiation therapy affects resting state brain networks in pediatric patients diagnosed with primary brain tumors. By utilizing functional imaging techniques, the study will assess alterations in brain connectivity that may correlate with cognitive decline following treatment. The research focuses on understanding the dose-dependent effects of proton therapy on cognitive functions, which is crucial for improving long-term outcomes for survivors. Participants will undergo cognitive testing and resting state MRI to gather comprehensive data on their brain function post-therapy.

Who should consider this trial

Good fit: Ideal candidates are children and young adults aged 8 to 21 with newly diagnosed primary brain tumors who will receive proton radiation therapy.

Not a fit: Patients with significant visual impairments, contraindications to MRI, or those requiring sedation for MRI scans may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better predictive models for cognitive decline in pediatric brain tumor survivors, ultimately improving their quality of life.

How similar studies have performed: While there have been studies on cognitive outcomes in pediatric brain tumor patients, this specific focus on resting state brain networks following proton therapy is relatively novel.
