Multiple Myeloma in Young Patients: Clinical Presentation and Treatment Approach

Abstract

Multiple myeloma (MM) in patients younger than 40 or 30 years accounts for only 2% and 0.3% of all myelomas, respectively. The presenting clinical and laboratory features are similar to those observed in patients of all ages who have myeloma, except a higher proportion of young patients have only light-chain myeloma. Some very young patients, particularly those younger than 30 years, have multiple skeletal lesions with extramedullary spread and a small M-component with few bone marrow plasma cells. In young patients with MM, particularly in those with good prognostic features (that is, normal renal function or low β2-microglobulin level) and also in those younger than 30 years, the survival is longer than that in series of patients of all ages with MM. Young patients with MM might benefit from early high-dose therapy followed by autologous or allogeneic stem cell rescue. The current status of autologous and allogeneic transplantation in MM is reviewed.
