[Significance of Neutrophil/Lymphocyte Ratio in the Prognosis of Patients with Multiple Myeloma].

Objective: To study the value of neutrophil/lymphocyte ratio (NLR) in the evaluation of prognosis of patients with multiple myeloma (MM).
Methods: NLR was calculated on the basis of the blood routine examination results of 65 patients with primary MM (MM group) and 83 persons receiving physical examination as control group, and the difference in 2 group was compared; moreover according to the median as threshold, the patients were divided into low NLR group (NLR＜2.34) and high NLR group (NLR≥2.34); the differences of age, sex, serum calcium β ₂ (Ca), microglobulin (β ₂ -MG), albumin (Alb), serum creatinine (Cr), hemoglobin (Hb), red blood cell distribution width (RDW) and lactate dehydrogenase (LDH) in 2 group were analyzed, and the survival rate was compared between the high and low-NLR group.
Results: the NLR of MM patients was statistically significantly higher than that of the control group (z=-2.415, P＜0.05). Compared with the low NLR group, the β ₂ -MG and Cr levels of patients in the high NLR group seemed higher, but the difference was not statistically significant. The single-factor analysis showed that NLR, β ₂ -MG and Alb levels were risk factors for the prognosis of MM patients, and the multi-factor analysis showed that NLR and Alb level were independent risk factors influencing the prognosis of MM patients.
Conclusion: NLR elevation in patients with primary diagnosis of MM indicates a poor prognosis, which is an independent risk factor affecting the prognosis.
