Glioblastoma is a tumour rich in molecular abnormalities. PDGFRs are important in growth signalling pathways and neoangiogenesis of gliomas. PDGF ligands and PDGFR-alfa are expressed in most human gliomas, while PDGFR-beta is expressed in glioma cells and tumor endothelial cells, PDFGR-α is expressed in most human gliomas. Imatinib mesylate exhibited antiglioma activity in preclinical studies, sensitizes glioma cells to radiation injury, and combined with hydroxyurea has shown promising results in the recurrent setting.
