    Multiple myeloma is highly treatable but rarely curable. The median survival in the prechemotherapy era was about 7 months. After the introduction of chemotherapy, prognosis improved significantly with a median survival of 24 to 30 months and a 10-year survival rate of 3%. Even further improvements in prognosis have occurred because of the introduction of newer therapies such as pulse corticosteroids, thalidomide, lenalidomide, bortezomib, and autologous and allogeneic stem cell transplantation, with median survivals now exceeding 45 to 60 months.[33,34,35,36] Patients with plasma cell leukemia or with soft tissue plasmacytomas (often with plasmablastic morphology) in association with multiple myeloma have poor outcomes.[16,37]

    Multiple myeloma is potentially curable when it presents as a solitary plasmacytoma of bone or as an extramedullary plasmacytoma. (Refer to the Isolated Plasmacytoma of Bone and Extramedullary Plasmacytoma sections of this summary for more information.)

    Amyloidosis Associated With Plasma Cell Neoplasms

    Multiple myeloma and other plasma cell neoplasms may cause a condition called amyloidosis. Primary amyloidosis can result in severe organ dysfunction especially in the kidney, heart, or peripheral nerves. Clinical symptoms and signs include the following:

    Elevated serum levels of cardiac troponins, amino-terminal fragment brain-type natriuretic peptide, and serum-free light chains are poor prognostic factors.[38,39] A proposed staging system for primary systemic amyloidosis based on these serum levels requires independent and prospective confirmation.[38]
