Liquid biopsy for diagnosing glioma tumors

The circTeloDIAG: a New Approach of Liquid Biopsy for the Diagnosis and Follow-up of Patients With Glioma Tumor

Hospices Civils de Lyon · NCT04931732

This study is testing if a simple blood test can help doctors find and understand glioma brain tumors better, making it easier to decide on the right treatment.

What this trial studies

This observational study focuses on the use of liquid biopsy to detect glioma-specific oncogenic processes in peripheral blood, particularly through the analysis of circulating tumor DNA (ctDNA). Gliomas are the most common primary brain tumors, and their diagnosis is crucial for effective patient management. The study aims to refine glioma diagnosis by identifying molecular biomarkers that can aid in differentiating tumor grades and guiding treatment decisions. By utilizing liquid biopsy, the study seeks to establish a routine clinical testing method for gliomas, which currently lacks standardized approaches.

Who should consider this trial

Good fit: Ideal candidates for this study are adult patients with suspected newly or recurrent glioma (grade II or higher) who are eligible for surgical intervention.

Not a fit: Patients with suspected grade I tumors or those who refuse surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate and timely diagnoses of gliomas, improving treatment outcomes for patients.

How similar studies have performed: While liquid biopsy has shown promise in other cancers, its application for gliomas is still novel and untested in routine clinical settings.
