In order to investigate the efficacy of bevacizumab on the treatment of radiation cerebral necrosis, patients who were diagnosed with radiation cerebral necrosis by imaging after stereotactic radiotherapy were collected. Bevacizumab was applied at a dose of 5 mg/kg once every three weeks at least three times. The changes in cerebral necrosis symptoms before and after treatment, the cerebral edema volume, the cerebral necrosis volume, and the changes in magnetic resonance imaging (MRI) strengthening phase signals of cerebral necrosis were used as the first observation point. The side effects of bevacizumab were used as the second observation point. Total of 14 radiation cerebral necrosis patients were treated with bevacizumab between June 2011 and February 2013 were collected. There were 12 symptomatic patients, of whom 10 patients (83.3%) had reduced symptoms. The edema index grades of nine patients (64.29%) improved. The cerebral necrosis volumes of 13 patients (92.86%) decreased. The T1 phase signal strengths of the intracranial enhanced MRIs of 12 patients (85.71%) significantly decreased. The clinical side effects of bevacizumab were mild. In conclusion, Preliminary results showed that treatment of radiation cerebral necrosis using bevacizumab was safe and effective. This treatment measure is worthy of further study.
