[Advances in biology and pathogenesis of multiple myeloma].
Plasma cell malignancy, multiple myeloma, is the prototype of monoclonal terminal-differentiated B cell proliferation that reveals a monoclonal Ig in the serum and/or urine of the majority of patients. New insights into the biology and pathogenesis of this entity are based on careful research to a complex cytokine network including TNF beta, IL-1 beta, and IL-6, many oncogene products such as bc1-2 protein, H-ras p-21 protein, and RB-1 product, and cell surface antigens associated with myeloma cells. The recent understanding on the mechanism for acquisition of IgV region diversity during B cell development has clarified the origin of the clonogenic cell in multiple myeloma. Further identification of new prognostic parameters as well as new therapeutic agents is necessary for the rational therapy of this refractory malignancy.
