Stringent complete remission of primary plasma cell leukemia with reduced-dose bortezomib, lenalidomide and dexamethasone: A case report and review of the literature

摘要

Plasma cell leukemia (PCL) is an aggressive variant of multiple myeloma characterized by a high level of plasma cells circulating in the peripheral blood. The prognosis of PCL patients treated with conventional chemotherapy remains poor. Some reports have suggested that both bortezomib and lenalidomide are effective in treating PCL. We herein report a case of primary PCL in which the patient achieved stringent complete remission after receiving combination chemotherapy with reduced-dose bortezomib, lenalidomide and dexamethasone (VRd). This regimen was very effective, and no severe adverse events were observed. A reduced-dose VRd regimen can be considered in PCL patients.
