title: [Antiangiogenic therapy for gastrointestinal tumors].
abstract: Angiogenesis plays a major role in the pathogenesis of many disorders. Vascular endothelial growth factor has been shown to be the key regulator of normal and pathological angiogenesis. Increased expression of VEGF has been associated with tumor neovascularization, metastasis and proliferation of cancer cells. Bevacizumab, a monoclonal antibody against VEGF, has shown promising preclinical and clinical activity against different types of cancer, particularly in combination with chemotherapy. There is an increasing evidence that bevacizumab has a disease-modifying effect in metastatic colorectal carcinoma (CRC), and also in advanced hepatocellular carcinoma. Further investigation is needed to evaluate the role of antiangiogenic therapeutic strategies in other gastrointestinal malignancies. This review summarizes recent knowledge about antiangiogenic therapy for gastrointestinal cancers.
