To study the expression level of serum B-cell maturation antigen (sBCMA) in the peripheral blood of newly diagnosed multiple myeloma (MM) patients, and explore its relationship with the prognosis of MM patients. The peripheral blood of 31 newly diagnosed MM patients and 30 healthy volunteers were collected. The level of sBCMA in the peripheral blood was detected by enzyme-linked immunosorbent assay (ELISA). The correlation between the level of sBCMA and the prognosis of MM patients was analyzed. The level of sBCMA in newly diagnosed MM patients was significantly higher than that in healthy controls ( <0.05). The level of sBCMA was closely related to the plasma cells ratio in bone marrow, the M protein level and the treatment ( <0.05). The level of sBCMA was negatively correlated with the overall survival (OS) of MM patients ( =-0.47). MM patients with low expression of sBCMA had significantly longer OS than patients with high expression of sBCMA ( <0.05). The level of sBCMA is significantly increased in MM pa
