Value of Neutrophil/Lymphocyte Ratio and Monocyte/Lymphocyte Ratio in the Prognosis of Patients with Multiple Myeloma / 中国实验血液学杂志

ABSTRACT

OBJECTIVE@#To investigate the effect of neutrophil/lymphocyte ratio (NLR) and monocyte/lymphocyte ratio (MLR) in the valuation prognosis of patients with multiple myeloma (MM).@*METHODS@#The clinical data of 82 patients with initially diagnosed MM admitted to Gansu Provincial People's Hospital was analyzed retrospectively. NLR and MLR were calculated based on blood routine results respectively. The optimal cut-off point of NLR and MLR was determined according to the ROC curve, and the patients were divided into the high NLR/MLR group and the low NLR/MLR group. The general data, biochemical indicators and prognosis of the patients in each groups were compared respectively. The prognostic significance of the high NLR/MLR group and the low NLR/MLR group in patients between different treatment regimens and different clinical characteristics were analyzed. Risk stratification was designed based on NLR and high MLR as two risk factors, and the effect of risk factors, on the prognosis of MM patients were compared.@*RESULTS@#ROC curve analysis determined that the optimal cut-off point of NLR was 3.1 (sensitivity 75%, specificity 70.7%) and the optimal cut-off point of MLR was 0.34 (sensitivity 83.3%, specificity 53.4%). The lactate dehydrogenase (LDH) and mean platelet volume (MPV) were correlated to NLR and MLR (P<0.05). There were no significant difference in age, sex, serum calcium (Ca), β @*CONCLUSION@#Elevated NLR and MLR are associated with poor prognosis in MM patients and may serve as the cost-effective and readily available prognostic biomarkers.
