In this study, we investigated the significance of the combination of preoperative fibrinogen and the neutrophil-to-lymphocyte ratio (NLR) in predicting the survival of patients with non-small cell lung cancer (NSCLC).MethodsWe retrospectively enrolled 589 patients with NSCLC who underwent surgery. The univariate and multivariate Cox survival analyses were used to evaluate the prognostic indicators, including the combination of fibrinogen and NLR (F-NLR). The cut-off values for fibrinogen, NLR, and clinical laboratory variables were defined by the receiver operating characteristic (ROC) curve analysis. According to the ROC curve, the recommended cut-off values for fibrinogen and the NLR were 3.48 g/L and 2.30, respectively. Patients with both a high NLR (≥ 2.30) and hyperfibrinogenemia (≥ 3.48 g/L) were given a score of 2, whereas those with one or neither were scored as 1 or 0, respectively.ResultsOur results showed that F-NLR was an independent prognostic indicator for disease-free survival (DFS) [hazard ratio (HR), 1.466; 95% confidence interval (CI), 1.243–1.730; P < 0.001] and overall survival (OS) (HR, 1.512; 95% CI, 1.283–1.783; P < 0.001). The five-year OS rates were 66.1%, 53.5%, and 33.3% for the F-NLR = 0, F-NLR = 1, and F-NLR = 2, respectively (P < 0.001). Correspondingly, their five-year DFS rates were 62.2%, 50.3%, and 30.4%, respectively (P < 0.001). In the subgroup analyses of the pathological stages, the F-NLR level was significantly correlated with DFS and OS in stage Ⅰ and ⅢA cancers.ConclusionsPreoperative F-NLR score can be used as a valuable prognostic marker for patients with resectable early-stage NSCLC.
