In the last 20 years, only temozolomide has obtained indication for the treatment of High-grade glioma (HGG). Temozolomide during and later radiation therapy has doubled one year survival and is the standard treatment for glioblastoma. But 30% of glioblastomas receive only a biopsy as they can't be resected and don't get benefit from this treatment. They and should be treated immediately after the biopsy to prevent neurological deterioration but in spite of this approach they often deteriorate neurologically during radiotherapy. . An effective pre-radiation treatment should improve their prognosis and allow them to complete concomitant radiotherapy and temozolomide treatment. Bevacizumab in recurrent HGG displays 63% of objective responses when combined with irinotecan. But irinotecan is not the most active treatment in this disease.
