Objective. Inflammation plays an extremely considerable role in the development and progression of malignancies. Absolute neutrophil count (ANC) and mean platelet volume (MPV) in blood are associated with various inflammatory conditions and resulted in independent prognostic factors for lung cancer. However, whether ANC and MPV can be diagnostic markers for lung cancer remains unknown. This retrospective study investigated the roles of ANC and MPV, either alone or combined, in diagnosing lung cancer. Methods. This study analyzed data from lung cancer patients and healthy individuals in Wuxi People’s Hospital Affiliated with Nanjing Medical University. The Mann–Whitney U-test was performed to compare differences between lung cancer patients and healthy individuals. Spearman’s correlation analysis was used to assess correlations. Receiver operating characteristic (ROC) curves were performed to determine diagnostic accuracy. Results. 209 patients diagnosed with lung cancer and 236 healthy subjects were enrolled in this study. Levels of ANC and MPV increased in lung cancer patients compared with healthy individuals (P<0.001). ANC had statistically significant negative weak correlation with albumin concentrations (r=‐0.154, P=0.026), and MPV had statistically significant negative weak correlation with total protein concentrations (r=‐0.153, P=0.027) in lung cancer patients. ANC and neutrophil-to-lymphocyte ratio had statistically significant positive correlation in both lung cancer patients (r=0.756, P<0.001) and healthy subjects (r=0.639, P<0.001). MPV and platelet-to-lymphocyte ratio had statistically significant negative weak correlation in both lung cancer patients (r=‐0.242, P<0.001) and healthy subjects (r=‐0.325, P<0.001). ANC had sensitivity (SEN) and specificity (SPE) of 0.512 and 0.809, respectively, and the area under the curve (AUC) with 95% confidence interval (95% CI) was 0.656 (0.603-0.710). SEN and SPE of MPV were 0.928 and 0.708, respectively, and the AUC (95% CI) was 0.913 (0.889-0.938). When ANC and MPV were combined, SEN and SPE became 0.842 and 0.835, respectively, and the AUC (95% CI) became 0.919 (0.895-0.943). Conclusions. Compared with ANC or MPV alone, the combination of ANC and MPV can improve diagnostic ability to distinguish lung cancer patients from healthy subjects.

Objective. Inflammation-driven markers play a crucial role in tumorigenesis and tumor progression. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in blood are systemic inflammatory response markers. Some reports have showed that NLR and PLR are related to a poor prognosis in patients with lung cancer. However, little studies have reported whether NLR and PLR can be diagnostic markers for lung cancer. The aim of the current study is to investigate the roles of NLR and PLR in diagnosing lung cancer. Methods. This study analyzed data from lung cancer patients and healthy individuals in Wuxi People’s Hospital Affiliated with Nanjing Medical University. The Mann–Whitney U test was performed to compare differences between the lung cancer group and the control group. Based on white blood cell (WBC) counts, both lung cancer patients and healthy individuals were divided into the low-level group, moderate-level group, and high-level group. The Kruskal-Wallis test was applied to compare differences of NLR and PLR among those groups with different WBC counts. Spearman correlation analysis was used to assess correlations. Receiver operating characteristic (ROC) curves were performed to determine diagnostic accuracy. Results. 210 patients diagnosed with lung cancer and 261 healthy subjects were enrolled in this study. Levels of NLR and PLR increased in the lung cancer group compared with the control group ( P < 0.001 ). For the lung cancer group, NLR levels could rise with the increasing of WBC levels ( P < 0.001 ) while PLR levels had no significant variation with the increasing of WBC levels ( P = 0.206 ). For the control group, NLR levels could rise with the increasing of WBC levels ( P < 0.001 ) while PLR levels would decline with the increasing of WBC levels ( P < 0.001 ). In the lung cancer group, both NLR and PLR had no significant correlations with aspartate transaminase, urea, and glucose. The area under the curve (AUC) with 95% confidence interval (95% CI) of NLR and PLR to distinguish lung cancer patients from healthy subjects was, respectively, 0.684 (0.634-0.735) and 0.623 (0.571-0.674). When NLR and PLR were combined, AUC (95% CI) increased to 0.691 (0.642-0.740). Conclusions. NLR and PLR alone have moderate ability to distinguish lung cancer patients from healthy subjects. Furthermore, combination forms of NLR and PLR can improve diagnostic ability.

The aim of the present study was an assessment of NLR and PLR ratios and also C-reactive protein and hemoglobin concentrations prognostic values in non-small cell lung cancer patients (NSCLC). Studied group consisted of 95 NSCLC patients with different stages of disease. The reference group consisted of 57 healthy people and 10 with non-malignant lung lesions. For every investigated individual hematological parameters and CRP concentration were measured and also NLR and PLR ratios were calculated. Compared to the reference group, NSCLC cancer patients demonstrated significantly higher leukocyte count, absolute neutrophil count, platelet count, CRP concentration and significantly lower absolute lymphocyte count and hemoglobin concentration. The values of NLR and PLR in lung cancer patients were significantly higher than in the reference group. The area under ROC curve for CRP was significantly larger than for the rest of the studied parameters apart from NLR. The area under the ROC curve for NLR was significantly larger than for PLR. There were significant positive correlations between CRP and WBC (Rs=0.2887; P=0.0046), CRP vs. NLR (Rs=0.4127; P=0.0000), CRP vs. PLR (Rs=0.4009; P=0.0006), and also reciprocal correlation with hemoglobin (CRP vs. HGB Rs=-0.4753, P=0.0000). Univariate analysis confirmed dependencies between stage of disease, performance status, age, hemoglobin and CRP concentrations, leucocyte count, absolute neutrophil count, platelet count as also NLR and PLR values and probability of 5-year survival of patients. Multivariate analysis demonstrated, that apart from stage of disease and performance status, the independent prognostic factor in NSCLC was NLR higher than 2.5.

Abstract Background Lung cancer is the most prevalent cancer globally with a grim prognosis alongside a very high number of cancer-related deaths. Mean platelet volume (MPV) is the measure of platelet size and is considered a surrogate marker of platelet activation. Low MPV indicates exhausted platelets causing worse outcomes in cancer patients. As the correlation between platelet count/platelet size and lung cancer prognosis still remains a topic of debate, this meta-analysis was done to comprehensively evaluate the prognostic significance of MPV among lung cancer patients.Methods A systematic search of electronic databases PubMed, Embase, and Google scholar and additional sources for relevant studies were done with no language restrictions from inception to 7th May 2021. Overall Survival (OS) and Disease-Free Survival (DFS)/Progression-Free Survival (PFS) and hazard ratio (HR) with 95% Confidence Interval (CI) were pooled to evaluate the relation of MPV with OS/DFS. Subgroup analysis based on cancer type, clinical stage, sample size, median age, cut-off value, and study region was done to identify the cause of significant heterogeneity.Results Eleven studies with 2421 lung cancer patients were included in our analysis. Our analysis showed no significant association between MPV levels with OS (H.R.:1.07, 95%C.I.:0.84–1.35, p = 0.60) and DFS/PFS (HR:1.04, 95%C.I.:0.68–1.60, p = 0.84). Under subgroup analysis, studies conducted in countries other than China (HR:1.53, 95% C.I.=1.14–2.03, p < 0.001, I2 = 42.11%) and studies with advanced-stage lung cancer patients (HR: 1.84, 95% C.I.=1.19–2.82, p-value = 0.01, I2 = 0%) showed significant association between MPV levels and worse DFS/PFS.Conclusion Pretreatment MPV levels did not show prognostic significance except in advanced lung cancer cases. Large multicentric studies with large samples and long follow-up times are necessary.

e15558 Background: Exosome concentration is known to be higher in cancer patients than in healthy individuals. In this study, we observed that the levels of exosomes differ in tumor-draining pulmonary blood and in peripheral blood in animal models and human subjects at different pathological stages of lung cancer. Methods: Ten rabbits and 40 humans formed the study cohorts. Blood was collected from a peripheral vein in all groups, and pulmonary blood was collected intraoperatively from all groups, except the healthy human controls. Quantitative analysis of exosomes was performed by nanoparticle tracking assay, CD63 enzyme-linked immunosorbent assay, and western blotting. Results: The peripheral blood of lung cancer-bearing animals and patients with lung cancer carried higher amounts of exosome than that from healthy controls ( p < 0.01 and p < 0.001, respectively). Moreover, pulmonary blood from lung cancer-bearing animals and patients had significantly higher exosome levels, compared to preoperative peripheral blood ( p < 0.01 and p < 0.0001, respectively). In patients, pulmonary exosome levels showed higher correlation with pathological stages of lung cancer than the peripheral exosome levels. Conclusions: Exosome levels increased with increasing grade of lung cancer, and this trend was more prominent in the pulmonary than in the peripheral blood.
