Genetic and Molecular Characterization of Nervous System Lesions
Primary and secondary brain tumors, the leading cause of death from cancer before the age of 35, represent a complex and heterogeneous group of pathologies with a generally poor prognosis. Knowledge of these tumors has made enormous strides thanks to access to biological samples, leading to a much more robust, reliable and precise histo-pronostic classification, but also, increasingly, to the identification of theranostic targets. Despite these advances, there is a real need to refine diagnostic and prognostic classification, identify the biological mechanisms involved in the formation and progression of these pathologies, develop new targeted strategies, and devise minimally invasive follow-up methods (liquid biopsies). In addition, certain non-tumoral brain lesions (e.g. malformations) can be similarly classified according to their molecular and mutational profile. This project aims to make a decisive contribution to these objectives.
• Any patient operated on for a brain lesion (e.g. tumors: glioma, LCPSNC, meningioma, or rare tumor) and/or followed up for one of these pathologies.
• Age ≥ 18 years
• Consent or non-opposition of the patient or his/her legal representative (guardian) to participate in the study.
