Bleeding Disorders Associated with Cancer.

ABSTRACT

Cancer can be associated with several distinct coagulation defects which can lead to bleeding complications. The primary hyperfibrinolytic syndrome associated with acute promyelocytic leukemia has been well recognized and is one of the most severe bleeding disorders. Acquired hemophilia, while rare and not only seen in the oncology setting, can be triggered by a malignancy and must be promptly recognized in order to prevent catastrophic hemorrhage. Other, less serious coagulopathic states have been linked to cancer, including acquired von Willebrand disease. Finally, several anti-neoplastic drugs can alter hemostasis and increase the risk of bleeding. A good understanding of this field can help mitigate the risk of complications in the cancer patient.
