Outline of Final Research Achievements |
The aim of this study was to concur radiation necrosis of the brain. In a laboratory study, an optical radiation dose for formation of radiation necrosis was clarified in rats. Radiation necrosis stably appeared 6 months after 65 Gy of a single fraction. In the next study, key molecules for radiation necrosis will be elucidated using this model. In a clinical study, bevacizumab suppressed radiation necrosis, but not tumor tissue in previously irradiated meningioma. Recurrent meningioma could be distinguished from radiation necrosis by administration of bevacizumab. In radiation necrosis, efficacy of bevacizumab lasted 6 months after completion of bevacizumab therapy. And we reported pathological review of brain radiation necrosis.
