Brief summary
The main goal of this study is to evaluate and to determine the dose of a highly accurate irradiation (allowing to increase the dose delivered while restricting the risk of complication) in association with temozolomide.
Interventions
patients will receive from 6 to 7 weeks 5 days a week radiations. The dose of radiation will depend on the level they will be included.
patient will receive whatever the level 7 days a week, temozolomide at the dose of 75mg/m2 during radiotherapy period. They will then follow one month after the end the radiochemotherapy an adjuvant treatment corresponding to a 5 days treatments of temozolomide at the dose of 200mg/m2 every 28 days.
