It is generally considered that a patient with myeloma who also has established renal impairment is unlikely to do well. While this is sometimes the case, analysis of recent data shows: (a) of 2768 patients in the MRC database for the fourth to the sixth trials, 10/163 with serum creatinine 300-600 microm/l and 20/89 with serum creatinine 600 micro/l at presentation had renal failure as a recorded presenting feature, whatever the renal function, the most common presenting feature was bone pain; (b) that many patients have persisting evidence of reduced renal function yet survive for more than the median time of 36 months which applies to myeloma generally. Patients with renal impairment, especially those whose myeloma is brought to plateau by chemotherapy, should be assessed thoroughly for evidence of other than myeloma induced renal damage as both renovascular disease and prostatic obstruction in males are common in the elderly population at risk.
