Bevacizumab in high grade glioma: Is there a subgroup that benefits?

Abstract

Background: Prognosis for patients with original glioblastoma diagnosis remains poor. Antiangiogenic therapy with Bevacizumab in first line treatment did not lead to improvement in overall survival, while progression-free survival was prolonged by 3 to 4 months, in recent phase III studies. Bevacizumab therapy in glioblastomas is not successfully associated with any prognostic biological markers. Our study investigates the correlation between the use of bevacizumab and several clinical and molecular markers measured in gliomas everyday clinical practice.
