Low-dose bevacizumab is effective in radiation-induced necrosis.

ABSTRACT

BACKGROUND: Radiation-induced necrosis is a complication of brain irradiation. Treatment options are limited. METHODS: The response to treatment with low-dose bevacizumab in 2 patients with radiation-induced necrosis was reported. RESULTS: Both patients with metastatic melanoma, aged 48 and 51 years, had significant symptomatic and radiological improvement with low-dose bevacizumab treatment. Doses as low as 5 mg/kg every 6 weeks and 7.5 mg/kg i.v. every 4 weeks were used and were highly effective. CONCLUSIONS: Low-dose bevacizumab is a solid option in the management of edema associated with radiation necrosis.
