【摘要】OBJECTIVE To investigate the clinical characteristics and laboratory findings of patients with light-chain multiple myeloma. METHODS Fourty-three patients with light chain myeloma over a 13year period were analyzed retrospectively and 43 cases with IgG type myeloma in the same period were used as control. RESULTS Of the 43 patients, 28 were male, 15 were female, with an overall mean age of 57 years (range, 36-71). At the time of onset, the main symptoms were fatigue and dizziness (23 cases, 53.5%) and bone pain (25, 58.1%). The main signs were anemia (28, 65.1%) and bone pressure pain (23, 53.5%). Of 39 patients with determined staging, 38 were in stage Ⅲ and 1 stage Ⅰ. Renal function examinations were performed for 31 patients. Among them, 16 were in stage ⅢB and 15 in ⅡA. Hypercalcemia (≥3 mmol/L) occurred in 2 cases. Of 18 patients, 3 had proteinur ia ≥12 g per 24 hours. Osteolytic lesions appeared in 27 of 31 cases. No abnormal globulin peaks were found in the serum protein electrophoretic bands. Serum and urine immunoelectrophoresis showed that 10 cases were kappa light chain, 29 were lambda light chain and 4 were both.
