Risk Factors in Cancer Patients

Abstract

Numerous studies in recent years have proven that the oncological process is an independent risk factor for thrombosis. For a long period of time and at the moment, research is continuing on the pathogenesis of a prothrombotic state in cancer patients. It was shown that the degree of risk is influenced by such indicators as the histological type of tumor, the stage of development of the disease, surgery, duration and type of anesthesia, chemotherapy, hormonal therapy, age, the presence of central venous catheters, immobilization, thrombophilia, history of thrombosis, infections. Thrombosis in cancer patients is triggered by thrombogenic factors associated with the tumor, patient-associated factors and environmental factors. The tumor cell affects the balance of hemostasis by releasing procoagulant substances, profibrinolytic, proproteolytic and proaggregant activity, expression of adhesion molecules, secretion of proinflammatory and proangiogenic cytokines; new participants in the process have also been identified. Studies have confirmed the fact that inflammation and thrombosis are inextricably linked with each other and play an important role in the progression of the disease and metastasis. All this opens up new horizons for the development of modern innovative strategies for treating cancer patients and increasing survival.
