  • Patent number: 6426367
    Abstract: Disclosed are methods of selectively reducing the blood supply to a neoplastic region, such as a tumor region, thereby selectively causing necrosis of the neoplastic tissue without substantial necrosis of adjoining tissues. In particular, methods are disclosed of selectively reducing the blood supply to a neoplastic region, such as a tumor region, by causing selectively occlusion of blood vessels feeding the neoplastic region. The invention also provides methods of selectively causing anti-angiogenic action in a neoplastic region, such as a tumor region, with the result that new blood vessels are not formed to sustain the neoplasia. The methods employ intra-arterial injection of polyunsaturated fatty acids, preferably in the form of salts, preferably with a lymphographic agent, and optionally with an anti-cancer drug, and/or a cytokine. The invention also provides solutions of PUFAs, or salts of PUFAs, in combination with a lymphographic agent.

  • Patent number: 6380253
    Abstract: A method of stabilizing and potentiating action of molecules of known anti-angiogenic substances such as Angiostatin® or Endostatin® by using in coupling conjugation with cis-unsaturated fatty acids (c-UFAs) in the treatment of cell proliferative disorders uses c-UFAs chosen from linoleic acid, gamma-linolenic acid, dihomo-gamma-linolenic acid, arachidonic acid, alpha-linolenic acid, eicosapentaenoic acid, docosahexaenoic acid and cis-parinaric acid in predetermined quantities. Preferably, the c-UFAs are in the form of polyunsaturated fatty acids (PUFAs). Uncontrolled or undesirable angiogenic activity promotes cell proliferative disorders and tumor growth, which can be inhibited by the selective use of PUFAs with anti-angiogenic substances used selectively in conjunction with predetermined anti-cancer drugs. For treatment of glioma, a sodium salt of a PUFA is preferred to form an admixture with an anti-angiogenic substance and a selected anti-cancer drug.
