Despite recent advances in the treatment of malignant gliomas (World Health Organization grade III and grade IV tumors- Glioblastoma Multiforme, Anaplastic Astrocytoma and Anaplastic Oligodendroglioma), the overall prognosis remains poor. Tumor recurrence in malignant glioma is inevitable, and associated with reduced overall survival (OS). Bevacizumab is approved for use in progressive GBM as a second line treatment, and is associated with improvements in progression free survival (PFS). However, all GBM patients eventually recur on bevacizumab therapy, with a very short OS after bevacizumab failure. No FDA-approved therapy is available for this clinical setting. Etoposide crosses the blood-brain barrier and has activity in recurrent malignant gliomas. The use of bevacizumab with etoposide in recurrent malignant gliomas in the setting of bevacizumab resistance is evaluated in this review. Bevacizumab and etoposide combined therapy is associated with radiographic response and effectiveness in selected patients.
