Evaluating molecular changes in brain metastases

Evaluation of the Humoral and Tumoral Molecular Alteration Profile of Brain Metastases

NA · GCS Ramsay Santé pour l'Enseignement et la Recherche · NCT05848050

This study is testing how changes in genes and other molecules in brain tumors can help doctors understand them better and find better treatments for patients with these tumors.

What this trial studies

This study aims to analyze the molecular alteration profiles of brain metastases by comparing them to liquid biopsies obtained from blood and lumbar punctures. It focuses on identifying mutations, gene amplifications, and epigenetic changes through high-throughput sequencing and transcriptome analysis. The study is designed as a single-center, prospective, interventional exploration, requiring only a blood test and lumbar puncture from eligible patients. The goal is to enhance understanding of the genomic landscape of brain metastases and improve treatment strategies.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 or over with cerebral metastases from a solid cancer that can be surgically excised.

Not a fit: Patients with contraindications to surgery, lumbar puncture, or those who are pregnant or breastfeeding may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized and effective treatment options for patients with brain metastases.

How similar studies have performed: While this approach is exploratory, similar studies have shown promise in understanding molecular profiles in other cancer types, indicating potential for success.
