SpletThis process continues even as the tumor matures. Thus, upregulation of angiogenesis is a key step in sustained tumor growth and may also be critical for tumor metastasis. 1,4. VEGF is an activator of tumor angiogenesis 4. VEGF (also known as VEGF-A, but commonly referred to simply as VEGF) stands for "vascular endothelial growth factor." SpletA hallmark of pathologic angiogenesis is per-sistent growth of blood vessels (ie, sustained neo-vascularization). Angiogenesis that continues for months or years supports the progression of many neoplastic and nonneoplastic diseases.9,10 How-ever, both physiologic and pathologic angiogenesis are usually focal.
