Using 18F-DOPA PET-CT to Improve Treatment Planning for Recurrent High-Grade Gliomas

Contribution of Cerebral 18F-DOPA PET-CT Scan in High-grade Recurrent Gliomas : a Monocentric Pilot Impact Study on the Practices of Defining Target Volumes Before RAdiotherapy

Not applicable Interventional Central Hospital, Nancy, France · NCT04766632

This study is testing if a special type of scan can help doctors better see and measure brain tumors in patients with recurring high-grade gliomas to improve their treatment plans.

What this trial studies

This study investigates the effectiveness of 18F-DOPA PET-CT scans in accurately delineating tumor volumes for patients with recurrent high-grade gliomas. The research aims to compare the tumor volumes identified by PET-CT with those identified by traditional MRI methods, focusing on improving the planning of re-irradiation treatments. By analyzing the differences in tumor volume delineation, the study seeks to enhance treatment precision and potentially improve patient outcomes. The study will involve adult patients with a confirmed diagnosis of WHO grade III or IV glioma who have experienced a recurrence after standard treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with a histological diagnosis of WHO grade III or IV glioma who have experienced a local recurrence after standard treatment.

Not a fit: Patients who are undergoing their first treatment or have contraindications to new radiotherapy will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more accurate treatment planning and improved survival rates for patients with recurrent high-grade gliomas.

How similar studies have performed: While several studies have explored the use of amino acid PET in glioma treatment planning, this specific approach using 18F-DOPA PET-CT in recurrent cases is novel and has not been previously tested.
