To determine the prognosis of patients with non‐secretory myeloma. Methods: We studied 124 patients diagnosed with multiple myeloma who had no monoclonal protein detected on serum and urine immunofixation at diagnosis and on all subsequent follow up testing (non‐secretory myeloma). The overall survival (OS) of patients with non‐secretory myeloma was compared with 7075 patients with typical myeloma seen during the same time period in whom a monoclonal protein was detected at the time of diagnosis.
