Vascularization of cancer is a complex and heterogenous process where neoangiogenesis by sprouting is only one of the possible mechanisms that also include postnatal vasculogenesis, vessel incorporation, intussusceptive microvascular growth, glomeruloid angiogenesis and vascular mimicry. Furthermore, the mechanism of vascularization may also depend on the cancer type and the host tissue as well. Antivascular agents can be divided into angiosuppressive ones (endothelial cell proliferation inhibitors), vascular-targeted agents (microvessel disrupting agents) and anti-hypoxia agents (targeting the molecular pathways responsible for the development of the angiogenic phenotype). Since antivascular therapy is a special form of targeted therapy, it is necessary to apply it in a rational manner to consider the type of vascularization, the molecular background of the angiogenic phenotype, the stage of the disease and the standard anticancer therapy. Whithout such a fine-tuning, antivascular therapies cannot be integrated more successfully into the management of cancer patients.
