ABSTRACT
<p><b>OBJECTIVE</b>To analyze the clinical significance of corrected serum calcium(CSCa) in patients with multiple myeloma.</p><p><b>METHODS</b>The serum calcium levels of 320 patients with initial multiple myeloma were measured and corrected by serum albumin and its levels measured simultaneously. The differences of serum calcium levels were analyzed before and after the correction by serum albumin.</p><p><b>RESULTS</b>There was a significant difference between serum calcium and CSCa in MM patients (2.34±0.15 vs 2.6±0.17 mmol/L). The constituent ratio of patients with hypercalcemia was from 11.3% to 23.1% after correction, the MM patients with hypocalcemia was decreased from 42.8% to 7.8% after correction, and the patients with normal calcium level were increased. There was a significant difference between serum calcium level and CSCa in I, II, III stages of MM patients respectively(P<0.05). In the 320 patients, the incidence of anemia was 80%, renal failure was 20.9%, and myeloma bone disease was 68.8%. Calcium concentration in both anemia and renal insufficiency was higher than the normal group, and the difference was more significant after correction. In 220 cases of MM receiving chemotherapy, the median progression-free survival (PFS) was 15 months, and overall survival(OS) time was 20 months. The PFS and OS time of the patients with hypercalcemia were shortened, and the difference was very significant after correction(P<0.01).</p><p><b>CONCLUSION</b>Corrected serum calcium can more sensitively to reflect the diseases serious extent, thus indicating prognosis has better effect.</p>
