What this trial studies

This study aims to explore the role of plasma extracellular vesicles (EVs) in patients with meningiomas who are receiving radiotherapy. A total of 60 patients with confirmed meningiomas and indications for radiotherapy will have blood samples collected before, during, and after treatment, as well as during follow-up. The study will analyze these samples to identify potential biomarkers for tumor progression and to develop DNA methylation profiles for better risk stratification and clinical management of meningioma patients.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with confirmed meningiomas requiring radiotherapy and a Karnofsky Performance Score of 60% or higher.

Not a fit: Patients with previous tumor diseases within the last 5 years or those undergoing simultaneous chemo/immunotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring and personalized treatment strategies for meningioma patients.

How similar studies have performed: While the exploration of plasma EVs in cancer is a growing field, this specific approach in meningioma patients is relatively novel and has not been extensively tested.
