Complications and Management of Coagulation Disorders in Leukemia Patients

CONCLUSION

In summary, coagulation disorders are common in leukemia. Thrombosis is as common as in solid malignancies. It is difficult to predict which patients will have bleeding and/or thrombosis. We need better predictors and coagulation tests to identify such patients. More research with prospective randomized control studies is needed on the role of novel oral anticoagulants, anticoagulant choice, dosing, and duration in hematologic malignancies.
