The relationship between initial percentage of bone marrow plasma cells and survival was studied in a group of 70 patients affected with multiple myeloma. All patients had a complete follow-up. The initial percentage of plasma cells shows a highly significant correlation with survival. Moreover, the percentage of bone marrow plasma cells is also correlated with the levels of hemoglobinemia and serum or urinary monoclonal component. The patients were divided in three groups according to the percentage of bone marrow plasma cells: group A: less than 20%; group B: 21-40%; group C: greater than 41%. The mean survival times of these three groups are significantly different, as well as their survival curves. The initial percentage of plasma cells in bone marrow is an useful parameter for estimating survival and predicting prognosis, and it can be an additional factor in the clinical staging of multiple myeloma, while the effectiveness of therapy can be monitored by sequential bone marrow aspirates.

D009101	Multiple Myeloma	A malignancy of mature PLASMA CELLS engaging in monoclonal immunoglobulin production. It is characterized by hyperglobulinemia, excess Bence-Jones proteins (free monoclonal IMMUNOGLOBULIN LIGHT CHAINS) in the urine, skeletal destruction, bone pain, and fractures. Other features include ANEMIA; HYPERCALCEMIA; and RENAL INSUFFICIENCY.

D010950	Plasma Cells	Specialized forms of antibody-producing B-LYMPHOCYTES. They synthesize and secrete immunoglobulin. They are found only in lymphoid organs and at sites of immune responses and normally do not circulate in the blood or lymph.

D001853	Bone Marrow	The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.
