Abstract:
OBJECTIVE:To explore the immunophenotypic characteristics of bone marrow granulocytes (G) and their clinical significance in patients with multiple myeloma (MM).
METHODS:The granulocyte immunophenotypes of bone marrow in 70 MM patients (MM group) and 40 anemia patients (control group) were detected by flow cytometry, and its correlation with clinical characteristics was further analyzed. Univariate and multivariate regression analysis were used to screen factors that affected prognosis.
RESULTS:The CD56+G%, CD13+G%, CD22+G% and CD117+G% in MM group were higher than those in the control group (all P <0.05). CD56+G% and CD117+G% in CR+VGPR group were significantly lower than those in PR+MR+PD group (both P <0.05). The CD10+G% in RISS Ⅲ stage and Ca2+ ≥2.65 mmol/L groups were increased (both P <0.05). The CD56+G% in elevated lactate dehydrogenase, β2-microglobulin≥5.5 mg/L and hemoglobin <85 g/L groups were increased (all P <0.05), while the CD117+G% in high-risk cytogenetic positive group was decreased (P <0.05). The expression rate of CD molecules on granulocytes was divided into low (L) and high (H) groups according to the median value. The overall survival (OS) of the LCD56+G%, LCD13+G% and LCD22+G% groups was significantly prolonged (all P <0.05). CD13+G% and CD22+G% were independent risk factors for OS in MM patients (HR=0.443, 0.410, both P <0.05).
CONCLUSION:The CD56+G%, CD10+G% and CD117+G% are closely correlated with clinical features in MM patients, while CD13+G% and CD22+G% are closely correlated with prognosis. Detection of CD molecules expression on granulocytes may be used to evaluate prognosis and guide treatment.
