Current State of Evidence on Definitions and Management of High-Risk Multiple Myeloma.

Abstract

Purpose of review: This review aims to address the subgroup of patients with newly diagnosed multiple myeloma (NDMM) who have high-risk multiple myeloma (HRMM) and continue to experience poor outcomes despite recent therapeutic advances. We will explore various clinical, biochemical, imaging, genetic, and dynamic features associated with high-risk status, along with the different risk stratification tools developed to identify HRMM patients.

Recent findings: Although numerous parameters for defining HRMM have been proposed, a universally accepted definition remains absent. Studies have shown diverse treatment responses and varying outcomes in HRMM patients, prompting the development of tailored therapeutic approaches. Emerging evidence supports the need for refined definitions and more targeted strategies to improve HRMM management. HRMM patients represent an unmet need in NDMM treatment, and a standardized definition for HRMM is crucial for advancing research and clinical care. This review discusses current and future treatment options, the necessity for a consistent HRMM definition, and the importance of clinical trials focused on this high-risk group to bridge existing treatment gaps.
