About

The purpose of this pilot study is that exosomes constitute a more interesting support for analyzes allowing a broader screening of molecular alterations to be carried out with more reliable, more sensitive and more efficient results than the reference Foundation One Liquid CDx test.

Full description

Gliomas are the most common primary brain tumors in adults. The heterogeneity of tumors, the lack of reliable criteria for identifying different subtypes make their histopathological diagnosis and their management complex. The molecular profiling from circulating exosomes is one of the most promising approaches to better characterize gliomas.

We will demonstrate the superiority of detection by NGS of molecular abnormalities present in exosomes from glioblastomas, compared to detection by the Foundation One Liquid CDx test on ctDNA.

Detection of molecular abnormalities
Experimental group
Description:
Blood samples will be taken from 2 + 3 Cell-Free DNA Collection tubes (Roche): for the comparative performance of the two methods (main objective) 3 Cell-Free DNA Collection tubes will be collected at 3 months (post chemotherapy) to evaluate the clinical relevance of a new analysis of molecular alterations on exosomes
Treatment:
Genetic: Blood sampling
