[Thrombocyte function and problems of blood coagulation and fibrinolysis in head and neck cancer]

Platelet aggregation induced by ADP and collagen and five parameters of blood coagulation and fibrinolysis, (levels of fibrinogen, fibrinolytic activity of euglobulin, fibrinogen and/or fibrin degradation products, antiplasmin activity and antithrombin activity) were measured in patients with cancer of the head and neck. The results were compared with those from healthy controls. Enhancement of platelet aggregation, hyperfibrinolysis and hypercoagulable state were found in the circulatory blood of patients with cancer of the head and neck.
