Multiple myeloma (MM) is a malignancy of plasma cells characterized by the production of a monoclonal immunoglobulin, or paraprotein, which can be detected in the serum and/or urine. The clinical features include bone pain, anaemia, hypercalcaemia, renal impairment, recurrent infections associated with immunoparesis, abnormal bleeding tendency, amyloid and hyperviscosity syndrome. In most cases the cause is unknown, although there is evidence for certain aetiological factors including monoclonal gammopathy of undetermined significance (MGUS) [1]. MGUS is characterized by the presence of a paraprotein in the serum but <10% plasma cells in the bone marrow. There are no bone lesions or immunoparesis. The paraprotein concentration is usually <20 g/l and stationary, whereas in myeloma it is >20 g/l and rising. Despite its association with myeloma, the factors involved in the progression of MGUS to myeloma are not well understood [1].
