International audience. Renal failure, mostly related to myeloma cast nephropathy (MCN), is a frequent complication of multiple myeloma (MM), which occurs in up to 50% of patients during the course of the disease. Persistent renal failure in MM is associated with poor survival. Treatment of MCN relies on urgent symptomatic measures (alkalinisation, rehydration, correction of hypercalcemia, and withdrawal of nephrotoxic drugs), with rapid introduction of chemotherapy to efficiently reduce the production of monoclonal light chains (LC). Recent studies suggest that, in patients with MM and severe renal failure due to MCN, rapid removal of circulating LC, through intensive hemodialysis sessions using a new generation high cut-off dialysis membrane, might result in dialysis withdrawal in most patients. If the development of intensive therapy and new efficient chemotherapy agents (thalidomide, bortezomib, lenalidomide) has transformed the care and prognosis of MM, the modalities and safety of these therapeutic regimens in patients with renal failure remain to be defined. The association of bortezomib with dexamethasone should be considered currently as first-line treatment in patients with MM and impaired renal function.
