title: [Angiogenesis and antitumor therapy].
abstract: We have examined the most recent literature dealing with the relationship between tumor growth and neovascularization (tumoral neoangiogenesis). It is quite evident that antiangiogenic therapy against solid tumors has an important theoretical basis. Many antiangiogenic substances are presently under study, and some inhibitors of angiogenesis, such as TNP-740, platelet factor 4, linomide, tecogalan, etc., are currently being tested in phase 1 or 2 clinical trials. These studies have, however, underscored the possibility of numerous side effects due to the lack of specificity of these substances against endothelial cells. The most promising and rational use of antiangiogenic factors in anticancer therapy seems to be their association with traditional chemo- or radiotherapy. Gene therapy also offers considerable theoretical promise as demonstrated by the transfection of thrombospondin 1 complementary DNA into a human breast carcinoma cell line.
