[Correlation between Morphological Typing and Monoclonality of Bone Marrow Plasma Cells and Its Diagnostic Value for High-Risk Smoldering Multiple Myeloma].

In HR-SMM patients, the immature, primitive, reticular and flaming plasma cells in bone marrow are considered as abnormal plasma cells, and they are correlated with monoclonal plasma cells. The proportion of abnormal plasma cells in total plasma cells of bone marrow and the reduction extent of non-involved immunoglobulin level in patients have certain reference value for the diagnosis of HR-SMM.
