Abstract:
Objective:To explore the effect of neutrophil-to-lymphocyte ratio (NLR) in peripheral blood on the survival of patients with multiple myeloma (MM).
Methods:The clinical data of 195 patients with MM who were diagnosed in Wuxi People's Hospital Affiliated to Nanjing Medical University from January 2007 to December 2015 were retrospectively analyzed. According to NLR, the patients were divided into the low NLR group (NLR<3) or high NLR group (NLR≥3). The relationship between NLR and the parameters including clinical indicators, treatment response and overall survival of the patients was detected.
Results:There were 61 cases in the high NLR group and 134 cases in the low NLR group. Compared with the low NLR group, creatinine and serum calcium in the high NLR group were higher (all P < 0.05). Complete remission rate after initial induction therapy in the low NLR group (32.1%, 43/134) was higher than that in the high NLR group (16.4%, 10/61), and there was a statistically significant difference (χ2=5.218, P=0.022). Median survival time in the low NLR group (38 months) was longer than that in the high NLR group (27 months), with a statistically significant difference (P=0.022). Cox univariate and multivariate analysis showed NLR≥3 was a risk factor (P=0.024), but not an independent risk factor (P=0.064).
Conclusion:NLR is associated with creatinine and serum Ca, which can be used to evaluate the overall survival time and inductive treatment response in patients with MM.
