Glioblastoma multiforme is a malignant primary brain tumor for which no cure has been developed. However, with aggressive surgical resection, radiation, and the advent of temozolomide, the overall survival of patients with glioblastomas has improved significantly.

The role of Avastin in the management of recurrent glioblastomas is reviewed.
