Brief Summary
18F-Fluorothymidine is a recently developed PET tracer to image tumor cell proliferation. Very few data report an interest of using such a tracer for cerebral malignant tumor management. In our project, we want to compare the tumoral volumes obtained with PET and MRI, with the gold standard histopathological diagnosis according to the WHO grading malignancy scale and the Ki-67 proliferation index, for preoperative evaluation as much as for tumoral postoperative residue evaluation. Furthermore, we want to explore the interest of 18F-FLT-PET volume to better delineate tumoral volume in radiotherapeutic management of gliomas.

EXPERIMENTALInterventions
18 FLT will be provided by the Laboratoire des Radiopharmaceutiques- Université Bordeaux2, Hôpital Xavier Arnozan and prepared according to the method described by Grierson and Shields ( Grierson J, Shields A. Nucl Med Biol 27 :143-156 ; 2000). Specific activity of 18FLT will be more than 37 GBq/µmol (\>1Ci/µmol) corrected for decay at the end of bombardment of cyclotron target. Before tracer injection to patients, each dosis will be tested for pH and for radiochemical purity (\> 95%) via HPLC technique and thin layer chromatography. 18FLT dosis will be injected intravenously to the patients (10 mL of salted isotonic solution with less than 10 % (v/v) of ethanol (USP). Administrated activity will be calculated estimating total body surface of patient (2,6 MBq/kg ou 0,07 mCi/kg) with maximal activity of 185 MBq. PET acquisition will be realized as follows : Dynamic acquisition in 3D mode for 35 min, Iterative reconstruction (OSEM) with and without attenuation correction.
