摘要: The prognostic/predictive value of potential vascular endothelial growth factor (VEGF) signalling biomarkers was evaluated retrospectively using samples from two randomized Phase III studies (HORIZON II and III) investigating cediranib in metastatic colorectal cancer (mCRC). Baseline levels VEGF, soluble VEGF receptor-2 (sVEGFR-2) carcinoembryonic antigen (CEA) were measured plasma/serum collected patients participating HORIZON (n=860; FOLFOX/XELOX plus 20 mg (n=502) or placebo (n=358)) (n=1422; mFOLFOX6 (n=709) bevacizumab (n=713)). Median biomarker baseline determined cutoff values for the patient subgroups. data available 88–97% patients/study (>2000 patients). In both studies, high CEA associated with worse outcomes progression-free survival (PFS) overall (OS) independent treatment OS: hazard ratio (HR)=1.35 (95% confidence interval (CI): 1.12–1.63); CEA, HR=1.63 (1.36–1.96); HR=1.32 (1.12–1.54); HR=1.50 (1.29–1.76)). sVEGFR-2 not prognostic PFS/OS. predictive PFS/OS outcome to treatment; low a trend towards improved effect II. treatment-independent PFS OS studies.
