RT Journal Article SR Electronic A1 Hoyle, Brian T1 Predictive Molecular Biomarkers: Enriching Clinical Trial Populations for Glioblastoma JF MD Conference Express YR 2013 FD SAGE Publications VO 13 IS 6 SP 11 OP 12 DO 10.1177/155989771306004 UL http://mdc.sagepub.com/content/13/6/11.abstract AB This article discusses the results of a correlative study in the Phase 3 Temozolomide and Radiation Therapy With or Without Bevacizumab in Treating Patients With Newly Diagnosed Glioblastoma trial [Radiation Therapy Oncology Group (RTOG) 0825; NCT00884741; Sulman EP et al. J Clin Oncol 2013 (suppl; abstr LBA2010)]. The study examined the molecular predictors of outcome and response to bevacizumab (BEV) added to standard chemoradiation for patients with newly diagnosed gliobastoma. The study aimed to identify patients likely to respond to BEV during initial treatment for glioblastoma using a gene biomarker detectable in formalin-fixed, paraffin-embedded tissue.
