Anticoagulants and cancer. A review
Abstract:
Anticoagulants (heparin, warfarin, fibrinolysin and others) reduced incidence of cancer metastases by inhibiting the formation of a fibrin matrix indispensable for peripheral fixation of circulating cancer cells. Apart from their specific anticoagulant activity most of these substances interfere directly with cell growth and metabolism, stimulating also immunologic anticancer mechanism. In clinical cases, favourable results have been obtained in various forms of metastasizing cancer, and especially in Hodgkin's disease and leukemias, by combining anticoagulant and cytostatic treatment. The results observed in other forms of cancer, though promising, are still controversial. The potential dangers and side effects of anticoagulant treatment in cancer are discussed.
Insights
Anticoagulants, such as heparin and warfarin, can reduce cancer metastasis by preventing fibrin matrix formation. These drugs also directly impact cancer cells and boost immune responses, showing promise in clinical treatments.
Area of Science:
- Oncology
- Hematology
- Pharmacology
Background:
- Cancer metastasis involves the formation of a fibrin matrix essential for circulating tumor cell adhesion.
- Anticoagulant drugs possess properties beyond blood thinning that may affect cancer progression.
Purpose of the Study:
- To investigate the role of anticoagulants in inhibiting cancer metastasis.
- To explore the combined effects of anticoagulants and cytostatics in cancer treatment.
Main Methods:
- Review of existing literature on anticoagulant mechanisms in cancer.
- Analysis of clinical outcomes combining anticoagulant and cytostatic therapies.
Main Results:
- Anticoagulants demonstrated reduced incidence of cancer metastasis by inhibiting fibrin matrix formation.
- Combined anticoagulant and cytostatic treatment showed favorable results in Hodgkin's disease and leukemias.
- Efficacy in other cancer types remains controversial but promising.
Conclusions:
- Anticoagulants offer a potential therapeutic strategy against cancer metastasis through multiple mechanisms.
- Further research is warranted to clarify the benefits and risks of anticoagulant therapy in diverse cancer types.
