Abstract: |
Clonal plasma cell (PC) neoplasms are comprised of a number of interrelated and partially overlapping entities, ranging from benign to fully malignant, which are variously defined and categorized by burden of disease, presence of organ injury, anatomic location, and in some cases, unique constellations of signs, symptoms, and pathologic findings. This chapter highlights continued advances in both knowledge regarding the underlying pathophysiology of PC neoplasms, and their therapy, with a focus on multiple myeloma (MM) as the prototypical malignant PC disorder. In this context we emphasize minimal residual disease (MRD) testing for risk stratification, disease management, and decision making, and also highlight novel therapies with mechanisms-of-action beyond existing proteasome inhibitors, immunomodulatory agents, and monoclonal antibodies. © 2023 by Elsevier Inc.
