Endocan-expressing microvessel density as a prognostic factor for survival in human gastric cancer

Table 2 Correlation between endocan-microvessel density and vascular endothelial growth factor expression in gastric cancer (r = 0.167, P = 0.047), and between endocan-microvessel density and vascular endothelial growth factor receptor 2 expression in gastric cancer (r = 0.410, P = 0.000)

¹Endocan-MVD was divided into four groups (0, 1, 2, and 3) based on quartiles of Endocan-MVD number, which were 12.51, 18.86 and 25.88, respectively;

²VEGF and VEGFR2 were divided as follows: (-), no cell stained; (+), < 25% of cells stained; (++), 25%-50% of cells stained; (+++), > 50% of cells stained. VEGF: Vascular endothelial growth factor; VEGFR2: VEGF receptor 2; MVD: Microvessel density.
