Successful Bortezomib/dexamethasone Induction Therapy with Lenalidomide in an Elderly Patient with Primary Plasma Cell Leukemia Complicated by Renal Failure and Pulmonary Hypertension

Abstract

Primary plasma cell leukemia (PPCL) is a rare disease that progresses rapidly. In such cases, it is difficult to achieve remission, and early intensive chemotherapy is recommended. We herein describe the case of a 76-year-old man with PPCL complicated by renal failure and pulmonary hypertension. Bortezomib/dexamethasone induction therapy with lenalidomide was administered in association with continuous hemodiafiltration (CHDF). Complete remission was achieved after a single course of treatment, resulting in the cessation of CHDF. With the patient in remission, the administration of beraprost and bosentan resulted in improvements in the pulmonary hypertension. The results of this case report support the use of bortezomib/lenalidomide/dexamethasone combination therapy as an effective treatment for elderly PPCL patients with various complications.
