Abstract

Background: Bevacizumab is widely used and may cause life-threatening bleeding. We attempted to identify clinical characteristics associated with central nervous system (CNS) hemorrhage in a broad population. Methods: We performed a retrospective review of the FDA MedWatch database of adverse events reported with bevacizumab from 11/1997 to 5/2009. Our search used keywords: bleeding, hemorrhage, cerebral, intracranial, subarachnoid, cerebellar, hemorrhagic stroke and brain. Results: A total of 17,466 reports were included in the database: 154 described CNS hemorrhage in 99 patients, and 1,041 reports described non-CNS bleeds. Median age was 62 years, and the primary cancers were consistent with indications for bevacizumab. Patients received a median of three (1-36) doses of bevacizumab prior to the bleed. Thirty percent had documented history of hypertension. Sixteen patients with CNS hemorrhage were reported to have CNS metastases. Death was reported as a complication of hemorrhage in 48 %. The most common predisposing factor for CNS bleeds was use of medications associated with bleeding, followed by thrombocytopenia. Conclusion: In this database, 154 of 1,195 reports of bleeding associated with bevacizumab described a CNS bleed. Although CNS bleeds were not common, they were the reported cause of death in two-thirds of cases.
