The tumor microenvironment is critical in the initiation and progression of cancerous growth, which is dependent on the establishment of a functional vascular network supporting neoplastic proliferation. While the precise role of tumor angiogenesis in lymphoma pathogenesis remains under active investigation, emerging data on the proangiogenic properties of the neoplastic lymphoma cells and mechanism of vascular assembly suggest that angiogenesis is highly relevant to the biology and therapy of non-Hodgkin's lymphoma. Antiangiogenic therapies in non-Hodgkin's lymphoma are in various stages of clinical development aiming at distinct angiogenic pathways operative in endothelial cells and perivascular stromal cells. The major classes of available antiangiogenics include anti-VEGF, small molecule inhibitors targeting proangiogenic receptor tyrosine kinases and their downstream signal transduction pathways, as well as immunomodulatory compounds with antiangiogenic properties. Preliminary clinical data indicate therapeutic advantages associated with strategies targeting dual compartments of vascular cells and tumor cells, as well as multiple angiogenic pathways within the tumor microenvironment. This review summarizes recent applications of antiangiogenic strategies in non-Hodgkin's lymphoma based on current understanding of the biology of lymphoma angiogenesis.
