| Outline of Final Research Achievements |
1)Establishment of model rat and mouse of radiation necrosis in the brain：Wister rats were irradiated with 65 Gy X-ray. Five to 6 months after X-ray irradiation brain radiation necrosis was confirmed almost all rats by MRI and autopsy specimen.To establish smaller sized model, mice were irradiated with 70MeV proton with 60Gy-equivalent. The irradiated mice were treated with 2 different kinds of HIF-1 inhibitors (YC-1 and GN44028). Now these mice were observed with periodic MRI. Another couple of months will be mandatory to elucidate some conclusions.
2)Seven recurrent malignant glioma patients were treated with boron neutron capture therapy with the simultaneous use of bevacizumab to prevent the occurrence of symptomatic radiation necrosis. All cases showed favorable prolongation of overall survival without radiation necrosis.
