A, Kaplan-Meier curve showing the patients with VEGF over-expression have lower 5-year survival rate than those with VEGF low-expression (P = 0.0028). B, Among the patients of stage I/II, no significant difference of 5-year survival rate was found between patients with VEGF over-expression and low-expression (P = 0.554). C, Among the patients of stage III/IV, VEGF over-expression group presents lower 5-year survival rate than the VEGF low-expression group (P = 0.0025). D, The patients with dual survivin and VEGF over-expression have significant lower 5-year suvivial rate than those with dual survivin and VEGF low-expression group (P = 0.0003), and those with non-dual expression group (P = 0.001)
