The recurrent mutation IDH1Arg132His leads to the cellular accumulation of D-2-hydroxyglutarate (2-HG), thus representing a diagnostic marker (this change is almost specific for gliomas) and prognostic (mutated gliomas have longer survival) of interest. The main objective is to identify the patients with IDH1 mutated glioma by three complementary approaches -genetic (identification of IDH1 mutation in plasmatic DNA), biochemical (2-HG dosage in the urine of patients) and radiological (2-HG
