Arterial Thrombosis With Immunomodulatory Derivatives in the Treatment of Multiple Myeloma: A Single-Center Case Series and Review of the Literature

Abstract

Although the increased risk of venous thrombotic events with thalidomide in multiple myeloma (MM) has been well described, an association with an increased risk of arterial events is less well appreciated. We describe 5 unusual arterial thromboses in patients with MM shortly after beginning thalidomide-based therapies. The cases are remarkable for a paucity of risk factors and short latency. We also review the literature on arterial thromboembolic events in patients taking thalidomide. Care should be taken in future trials to document arterial events with both thalidomide and lenalidomide.
