Gliomas comprise approximately 2% of all cancers but have been increasing in incidence over the past 50 years. They result in considerable patient morbidity, and until recently, median overall survival (OS) for patients with glioblastoma multiforme (GBM), the most aggressive form of glioma, was generally < 1 year, with almost all patients succumbing to their disease within 2 years of diagnosis. The combination of an orally available alkylating agent and radiation therapy in a phase III trial yielded a median OS exceeding 14 months in patients with newly diagnosed GBM. Management of recurrent GBM is an unmet medical need, with no standard treatment options and a 6-month progression-free survival (PFS) rate of only 15%. Because GBM is a highly vascularized tumor, antiangiogenic approaches have been explored. Recent trials of antibodies to vascular endothelial growth factor (VEGF) alone or in combination with chemotherapy have demonstrated 6-month PFS rates of 25%-50%. Other antiangiogenic approaches, such as decoy receptors of VEGF, VEGF receptor (VEGFR) tyrosine kinase inhibitors, and VEGFR-binding agents, have also been investigated. Several ongoing clinical trials are further investigating the use of angiogenesis inhibitors in the treatment of GBM.
The purpose of this activity is to update physicians on new developments with chemotherapy and targeted agents in the treatment of GBM.
This activity is intended for medical oncologists involved in the care of patients with gliomas. No specific skills or knowledge other than a basic training in oncology is required for successful participation in this activity.
