Werther et al. (A-21) examined the vascular endothelial growth factor (VEGF) concentration in blood from colon cancer patients. Research suggests that inhibiting VEGF may disrupt tumor growth. The researchers measured VEGF concentration (ng/L) for 10 subjects and found an upward trend in VEGF concentrations during the clotting time measured at baseline, and hours 1 and 2.
