[Blood coagulation disorders in oncological patients].

Patients with malignancies often experience acute disorders of coagulation. They may manifest as thromboembolism, disseminated intravascular coagulation or a tendency to bleed. Either disorder carries a high rate of complications and a difficult task in diagnosing and treating them. Some complications typical for patients with malignancies are discussed. Among these are tumor associated thrombophilia, acquired von Willebrand's disease, and thrombocytopenia.
