Definitions

  • the present invention relates to the use of fibrinolytics in the fight against tumors.
  • tPA and fibrinolytics have been used to treat thrombotic diseases such as Heart attack used (see Red List 1988, Group 41 - fibrinolytics).
  • fibrinolytics increase the blood flow to tumors.
  • the simultaneous administration of fibrinolytics and antitumor agents used in tumor therapy considerably increases the concentration of the latter in the tumor, so that tumors can be combated more effectively or the application doses of antitumor agents, which are generally not particularly well tolerated, are reduced with the same effectiveness can be.
  • the combination of fibrinolytics and anti-tumor agents in the isolated perfusion of organs or parts of the body also appears to be particularly interesting in this context. The same applies to the oxygenation of the tumor tissue during radiation therapy, which works better the more blood is supplied to the tumor tissue to be destroyed.
  • the invention relates to the use of fibrinolytics to increase the blood circulation of. Tumors.
  • Suitable fibrinolytics are, in particular, urokinase, prourokinase, streptokinase and tPA (tissue plasminogen activator) and muteins derived from these substances. Muteins of these proteins are to be understood as meaning substances which differ from the proteins mentioned by the exchange, deletion or addition of amino acids.
  • fibrinolytics are also suitable as fibrinolytics.
  • eminase pentosan polysulfate and combinations of streptokinase and streptodornase (cf. Red List 1988, No. 41 004, 41 006, 41 012 and 41 013).
  • the fibrinolytics are usually used in the usual dosages (cf. Rote Liste 1988, Group 41).
  • tPA the dose is around 0.1 to 10 mg per kg body weight.
  • Fibrinolytics are usually administered intravenously at the same time as, or shortly before, the antitumor agent or shortly before the start of radiation.
  • anti-aging agents examples include:
  • antibiotics such as actino ycin D, doxorubicin (adriamycin), daunorubicin, mithramycin, pepleomycin, mitomycin C and bleomycin, as well as other substances with an interchatory action, such as amonafluid and mitonafide,
  • alkaloids such as vincristine, vinblastine, vindesine, etoposide and teniposide
  • alkylating substances such as cyclophosphamide, thiotepa, melphalan, nitrosoureas and cisplatin and
  • Antimetabolites such as methotrexate, 5-fluorouracil and its analogues, 6-mercaptopurine, 6-thioguanine and cytarabine.
  • the tumor agents are used in the usual dosages (see Rote Liste 1988, monkey 85). In a number of cases, however, it is also possible to use smaller amounts.
  • the dose ranges for TMF and LT are 1 to 500 ⁇ g / m body surface and for interleukins 1 to 1000 ⁇ g / m2 body surface.
  • Radio sensitizers such as misonidazole and metronidazole, can also be increasingly transported into the tumor in combination with fibrinolytics.
  • the efficiency of the radiation with ⁇ and j sites can thus be improved by adding fibrinolytics without changing the radiation dose.
