Abstract:
Objective:To investigate the relationship between neutrophil/lymphocyte ratio (NLR), lymphocyte/monocyte (LMR) ratio and prognosis in patients with advanced non-small cell lung cancer (NSCLC).Methods:Total 96 NSCLC patients with stage Ⅲ B and above confirmed by pathological examination in our hospital from March 2014 to 2016 were selected as the research objects. According to the 24-month follow-up results, the patients were divided into survival group (30 cases) and death group (66 cases). The NLR and LMR values of the two groups before chemotherapy were compared. The critical value of NLR and LMR in predicting the prognosis of patients was analyzed by drawing receiver operating curve (ROC); The clinicopathological characteristics of NSCLC patients with different levels of NLR and LMR were analyzed, and Cox proportional hazard regression model was used to analyze the effect of NLR and LMR on the prognosis of patients.Results:The NLR value of survival group was lower than that of death group ( P<0.05), and there was no significant difference between survival group and death group in LMR value ( P>0.05). The area under curve (AUC) value of NLR was 0.785, and the corresponding critical value was 3.19; the AUC value of LMR was 0.536, and the corresponding critical value was 3.66. There were significant difference in tumor node metastasis (TNM) stage and differentiation between NSCLC patients with different NLR values (NLR≥3.19 group and NLR<3.19 group) ( P<0.05), but there were no significant differences in age, gender, smoking, pathological type and lesion location ( P>0.05). There was no significant difference in TNM stage, differentiation degree, age, gender, smoking, pathological type and lesion location in NSCLC patients with different LMR values (LMR ≥ 3.66 group and LMR<3.66 group) ( P>0.05). The increase of TNM stage, differentiation degree and NRL were independent risk factors of poor prognosis in patients with advanced NSCLC ( P<0.05). Conclusions:Increased NLR values in peripheral blood of patients with advanced NSCLC may increase the risk of poor prognosis in patients.
