KDR and cervical carcinoma: The significant association between elevated expressions of vascular endothelial growth factor (VEGF) and vascular endothelial growth factor receptor 2 (VEGFR-2) in cervical precancerous lesions and invasive cancers with worsening and poorer clinicopathological parameters suggests that targeting the VEGF/VEGFR-2 signaling pathway is an effective strategy for treating cervical cancer [7,8].
