Prior to transformation, many epithelial tissues (eg, in the gut, skin, and exocrine glands) are anatomically separated from the vasculature by basement membranes and/or connective tissue layers. These barriers are compromised during the malignant process, resulting in abnormal interactions between vascular components (endothelial cells, blood cells, plasma, or lymph) and cancer cells at this new tumor-vascular interface (Rak, 2009).
