“…In this study, we found that the increased levels of NLR and PLR were associated with worse clinical outcome, which was consistent with the previous studies (25,26), although the role of inflammation cell in the tumor pathogenesis was not fully elucidated.…”

Background: Small cell lung cancer (SCLC) is a subtype of lung cancer with poor prognosis. In this study, we aimed to build a nomogram to predict the survival of individual with SCLC by incorporating significant clinical parameters. Methods:The patients with SCLC were enrolled from the First Affiliated Hospital of Guangzhou Medical University (GMUFAH) between 2009 and 2013. We identified and incorporated the independent prognostic factors to build a nomogram to predict the survival of SCLC patients. The predictive accuracy and discriminative ability of the nomogram were evaluated by concordance index (C-index) and calibration curve.We also compared the accuracy of the built model with the 7 th AJCC TNM and VALSG staging system. The nomogram was further validated in an independent cohort of 80 patients with SCLC from Cancer Center of Guangzhou Medical University (GMUCC) between 2009 and 2013.Results: A total of 275 patients with SCLC were included in the primary cohort, and seven independent prognostic factors were identified including age, N stage, metastasis status, histology, platelets to lymphocyte ratio (PLR), neuron specific enolase (NSE) and CYFRA21-1 as independent prognostic factors after using Cox regression model. A nomogram incorporating these prognostic factors was subsequently built. The calibration curves for possibilities of 1-, 2-year overall survival (OS) revealed optimal agreement between nomogram prediction and actual observation. The C-index of this nomogram was higher than that of TNM Conclusions:In this study, we established and validated a novel nomogram for the prediction of OS for the patients with SCLC. This model could provide more accurate individual prediction of survival probability of SCLC than the existing staging systems.

“…The study published by Mitchell et al (29) included patient data from 33 countries. The included studies evaluated 16 populations of patients with NSCLC (17-24,26-29,31-34) and 2 populations of patients with SCLC (25,30). The 2 studies on SCLC reported tumor staging information as limited and extensive disease, so only the staging information from the studies regarding NSCLC were considered Only 1 study by Sarraf et al (17) evaluated all tumor stages, 8 studies evaluated early-stage tumors (23,(26)(27)(28)(29)(31)(32)(33), and 6 studies evaluated late-stage tumors (18,(20)(21)(22)24,34).…”

Abstract. Current evidence suggests that the neutrophil-to-lymphocyte ratio (NLR) may be a biomarker for poor prognosis in lung cancer, although this association remains controversial. Therefore, a meta-analysis was performed to evaluate the association between NLR and lung cancer outcome. A systematic literature search was performed through the PubMed, Embase and Cochrane Library databases (until July 30, 2016), to identify studies evaluating the association between NLR and overall survival (OS) and/or progression-free survival (PFS) among patients with lung cancer. Based on the results of this search, data from 18 studies involving 7,219 patients with lung cancer were evaluated. The pooled hazard ratio (HR) suggested that elevated pretreatment NLR predicted poor OS [HR=1.46, 95% confidence interval (CI): 1.30-1.64] and poor PFS (HR=1.42, 95% CI: 1.15-1.75) among patients with lung cancer. Subgroup analysis revealed that the prognostic value of NLR for predicting poor OS increased among patients who underwent surgery (HR=1.50, 95% CI: 1.21-1.84) or patients with early-stage disease (HR=1.64, 95% CI: 1.37-1.97). An NLR cut-off value of ≥4 significantly predicted poor OS (HR=1.56, 95% CI: 1.31-1.85) and PFS (HR=1.54, 95% CI: 1.13-1.82), particularly in the cases of small-cell lung cancer. Thus, the results of the present meta-analysis suggested that an elevated pretreatment NLR (e.g., ≥4) may be considered as a biomarker for poor prognosis in patients with lung cancer.

“…Recent studies have suggested that a systemic inflammatory state is associated with the malignant biological behavior of the tumor (14,15). In particular, the neutrophil-lymphocyte ratio (NLR) has been evaluated as a predictor of prognosis in various types of solid tumor, including gastric, colorectal, pancreatic, breast and lung cancers (16)(17)(18)(19)). An elevated NLR has already been shown to be associated with poor prognosis in patients with HCC treated by liver transplantation, surgical resection, or TACE (20)(21)(22).…”

Abstract. Sorafenib is currently the only efficient molecular targeted therapy for hepatocellular carcinoma (HCC), although its effect is relatively moderate and variable between individuals. The present study aimed to evaluate the significance of peripheral blood neutrophils in the prognosis of HCC patients treated with sorafenib. A total of 464 patients with HCC were treated with sorafenib at Zhongshan Hospital (Shanghai, China) between January 1st, 2008 and December 31st, 2012, among which 120 patients were enrolled in the study. The optimal cutoff point for low vs. high neutrophil count (3.65x10 9 ) was obtained from a receiver operating characteristic curve. Overall survival (OS) was compared between the patients with low and high peripheral neutrophil counts. Univariate and multivariate analyses were used to explore the prognostic factors associated with OS in the patients treated with sorafenib. A nomogram model was also performed to predict the OS times of these patients. The median OS time was 9.0 months (95% confidence interval, 5.9-12.1 months) in the whole group of patients, with 1-, 2-and 3-year OS rates of 36, 24 and 16%, respectively. Using a cutoff level of 3.65x10 9 neutrophils/l, the median OS time was longer in the group of patients with a low peripheral neutrophil count than in those with a high peripheral neutrophil count (11.5 vs. 5.0 months, respectively; P<0.001). The multivariate analysis showed that peripheral neutrophil count, α-fetoprotein level and tumor size were independent prognostic factors for OS. In addition, using the nomogram model for the prediction of OS, the Harrell's c-index was 0.79. Therefore, it was concluded that a lower peripheral blood neutrophil count was associated with a better prognosis following treatment with sorafenib therapy.

High pretreatment neutrophil–lymphocyte ratio predicts recurrence and poor prognosis for combined small cell lung cancer

Abstract: High pretreatment NLR (≥4.15) is a potential useful indicator for C-SCLC recurrence and predicts a poor long-term prognosis for C-SCLC, which should be considered in defining the prognosis with other well-known prognosticators in C-SCLC patients.
