Bevacizumab induced reversible thrombocytopenia in a patient with recurrent high-grade glioma: a case report.

We report a case of bevacizumab (BEV)-induced thrombocytopenia in a 36-year-old woman treated with BEV as a single-agent for a recurrent high-grade glioma. The thrombocytopenia was both reversible and reproducible on multiple treatment cycles. The patient has improved clinically and by brain MR imaging with single-agent BEV for approximately 7 months to date. She did not have bleeding or thromboembolic complications. Treatment delays have been 1-2 weeks relative to a conventional plan of treatment, i.e., 10 mg/kg every 2 weeks. This is a rare complication that has not been previously reported.
