Multiple myeloma in the region of Bursa, Turkey: a retrospective analysis.
We evaluated the clinical and laboratory features of multiple myeloma in our patients and reviewed the factors that affected their survival. The study included 36 patients (12 women and 24 men) with multiple myeloma whom we followed up until death between October 1978 and June 1995. The age range was 34 to 75 years (mean age, 53.9). The chief complaints on admission were lumbar pain and pain in the extremities (77.8%) and generalized weakness (61.1%). The most common laboratory findings were severe anemia (hemoglobin < 8.0 g/dl) (50%), elevated erythrocyte sedimentation rate (75%), monoclonal spike in the serum protein electrophoresis (44.4%), and lytic skull lesions (72.2%). Twenty-three (64%) patients had a monoclonal IgG, 9 (25%) had IgA, 1 had IgD, 2 had light chain disease, and 1 was nonsecretory. Localized plasmacytoma was detected in 4 patients and 4 patients had amyloidosis in rectal and gingival biopsies. According to the Durie-Salmon staging system, 2 patients were in stage 1, 8 were in stage 2, and 26 were in stage 3. The mean survival was 31.4 +/- 4.3 months (range: 1 to 96). The 5-year survival rate was 11%. Sex, age at diagnosis, stage of the disease, hemoglobin level, platelet count, level of serum calcium, creatinine, serum paraprotein, and type of paraproteinemia were tested as prognostic parameters. We could not establish a statistically meaningful effect of these parameters on survival time. The first and second most common causes of death were renal failure and infection, respectively.
