| Research Abstract |
There was a significant correlation between effectiveness of bevacizumab and uptake of F-BPA-PET in radiation necrosis. Reduction of perilesional edema by bevacizumab contributed to improvement of performance status in patients with radiation necrosis. In pathological study, reactive astrocytes and monocytes played important roles, expressing HIF-1alfa, VEGF, CXCR4, CXCL12, PDGR, and PDGF-R. We have still tried to establish experimental radiation necrosis in rats.
