Inclusion Criteria: * Clinical criteria:- - age\> to 18 years * GBM de novo * Histological evidence is essential. A minimum interval of 7 days is required between biopsy and neo-adjuvant therapy. A minimum interval of 15 days is required for open skull surgery and neo-adjuvant therapy. * The insertion of patients is a WHO score 3 and 4 in relation to the neurological deficit is possible by definition * Biological criteria \- Polynuclear neutrophils\> 1500 / mm3 * pads\> 100,000 / mm3 * SGOT \<5 at the upper limit of normal (ULN) * bilirubin \<1.5 x ULN * Creatinine \<1.5 ULN * proteinuria \<2 g / 24 hours * Forensic criteria * Patient with health insurance * consent signed by the patient if it is lucid, or by default by the person of trust. Exclusion Criteria: * 1\. Patients without neurological deficit (SN 0) or with moderate deficit (SN 1 or SN 2). 2\. In case of initial neurological deficit SN 3-4, the interest of a decompression surgery must be discussed. If the surgery is unsuccessful, a corticosteroid test, at least 4 days, with at least 1.5 mg / kg / day of prednisone equivalent, must be performed. If surgery and / or corticosteroids allow to return to an SN 0-2 neurological score with return to an RPA III, IV or V class, the patient is not included and must be treated according to a conventional chemoradiotherapy regimen with temozolomide (Stupp schema). 3\. Multifocal tumor or whose excessive volume does not allow to consider curative radiation therapy at a dose of 60 Gy. 3\. History of chemotherapy, (including Gliadel) and / or radiotherapy. 4. Cerebral or intratumoral haemorrhage on diagnostic MRI. However, microhemorrhages, haemosiderin deposits or haemorrhages secondary to biopsy or surgery are not contraindications. 5\. Concomitant serious uncontrolled pathology, including another evolving cancer 6. Uncontrolled infection 7. Uncontrolled Hypertension (PAS\> 160 mm Hg) Despite Optimized Treatment 8. Coronary artery disease or unstable arterial disease. Evolutionary aneurysm. Myocardial infarction less than 6 months old. 9\. Stroke or peripheral arterial disease less than 6 months old. 10. Heart Failure\> NYHA Grade II 11. Haemorrhagiparous disease (hemophilia, Willebrandt ...) 12. History of hemoptysis less than 1 month old. 13. Pulmonary embolism less than 1 month old. 14. Anticoagulant or antiplatelet therapy in progress. If possible, these treatments should be stopped before inclusion after consultation with a cardiologist or angiologist. However, these treatments may be continued if their discontinuation is considered harmful and that the participation in the trial is considered beneficial for the patient with regard to the haemorrhagic risk incurred. 15\. Surgical procedure (other than craniotomy or stereotactic biopsy) less than one month old or foreseeable surgery. 16\. History of digestive fistula or intestinal perforation whose resolution is less than 6 months old. 17\. Pregnant or lactating patient (contraception to be prescribed if necessary) 18. Known intolerance to bevacizumab or temozolomide
