Introduction: Glioblastomas (GBM) frequently overexpress the epidermal growth factor receptor (wtEGFR) or its mutant, EGFRvIII contributing to radioresistance. New treatment strategies for GBM include blockade of EGFR signaling and angiogenesis. Cediranib (CD) is a highly potent VEGFR-2 RTKI that inhibits all three VEGF receptors. This study investigated the radiosensitizing potential of CD in combination with temozolamide (TMZ) in U87 GBM xenografts expressing wtEGFR or EGFRvIII.
