Management of multiple myeloma in older people

Abstract

Multiple myeloma is a neoplastic proliferation of a plasma cell clone that produces a monoclonal immunoglobulin. It is one of the most common haematological malignancies and the incidence increases with age, with a median age at diagnosis of 65-70 years. The diagnosis of multiple myeloma requires the presence of ࣙ10% plasma cells in the bone marrow and an M-protein in serum and/or urine. Cytogenetic status, serum β 2 -microglobulin and response to therapy are the key prognostic factors. Treatment is necessary for the patient diagnosed with symptomatic multiple myeloma, with organ damage. Patients older than 65 years are ineligible for autologous transplantation. The introduction of novel agents, such as thalidomide, bortezomib and lenalidomide, have changed the management of myeloma and extended overall survival. However, in older patients the results are not as satisfactory and treatment strategies have to be individualized to improve tolerability and optimize efficacy.
