Antiangiogenic markers such as vascular endothelial growth factor A (VEGF-A), vascular endothelial cadherin (VE-cadherin) and microvessel density were evaluated in order to try to correlate the results of expression of these markers with the effect obtained on the tumor and also to assess the prognostic value of these markers on the treatment outcome in relation to other known prognostic markers [11]. The gene discussed is CDH5; the disease is neoplasm.
