| Measure | Time frame |
|---|---|
| Main Objective: valuation of the diagnostic performance of [18F]DPA-714 PET in grading obtained by stereotactic biopsies of glioma;Secondary Objective: Comparison of quantitative [18F]DPA-714 PET parameters with histological type (astrocytoma or oligodendroglioma). Comparison of quantitative parameters of [18F]DPA-714 PET with the presence or absence of an Isocitrate dehydrogenase type 1 (IDH1) mutation and the presence or absence of a 1p19q co-deletion. Comparison of quantitative [18F]DPA-714 PET parameters and tumor microenvironment characteristics. Translated with www.DeepL.com/Translator (free version);Primary end point(s): The diagnostic performance of quantitative [18F]DPA-714 PET uptake parameters will be evaluated. The diagnostic ability of each parameter, i.e., the categorization of each stereotactic biopsy according to its histological grade assessed in pathology, of each PET parameter will be evaluated by the area under the ROC curve, as well as the sensitivity, specificity, negative predictive value, positive predictive value, and accuracy rate for a given threshold maximizing the Youden index. There was no preferred diagnostic indicator chosen as the primary endpoint. The study is a pilot study and does not attempt to draw any definitive conclusions (inferences).

| Secondary end point(s): Quantitative [18F]DPA-714 PET parameters will be compared according to histological type (astrocytoma or oligodendroglioma), presence or absence of IDH1 mutation, 1p19q co-deletion, and the characteristics of the tumor microenvironment (i.e. presence and quantity of immune (CD45 marker), microglial/macrophagic (CD14, CD49d, CD68, CD163, HLA-DR, IBA-1 markers), endothelial (CD31) infiltrating cells; as well as the presence of tumor cells, and the presence of transcriptomic markers characterizing the tumor sample ;Timepoint(s) of evaluation of this end point: At surgery | — |
