Outcomes and Cost of Deep Venous Thrombosis Among Patients With Cancer

Abstract
Deep venous thrombosis (DVT) is a common complication of cancer and its therapy.1-10 In the case of some advanced cancers, DVT is the presenting clinical sign. In most studies of DVT and its treatment, a diagnosis of cancer is a poor prognostic sign.1-21 However, many studies do not report a separate analysis for cancer patients. Large epidemiological studies in this population are rare, and studies of the cost of DVT are very uncommon indeed. We herein report, to our knowledge, the largest study of the outcomes of DVT in cancer patients to date and describe the resources used in the management of DVT and their costs. We also examine risk factors for serious clinical outcomes such as DVT recurrence and pulmonary embolism (PE).
