Interestingly, the VEGF-A expression levels in the peritumor tissue were significantly lower than those in the tumor tissue (p < 0.001, z = 3.931), while the VEGFR2 levels were significantly higher in the peritumoral mucosa in comparison to the tumor tissue (p < 0.001, z = 4.56) [Figure 1]. Here, KDR is linked to neoplasm.
