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.

Abstract: Lung cancer is the leading cause of malignancy in the world reaching up to 13% of all cancer diagnoses. Platelet-to-Lymphocyte Ratio (PLR) and Neutrophil-to-Lymphocyte Ratio (NLR), are promising markers of inflammatory prognosis, clinical decisions for proper management of lung cancer patients. The research used a retrospective analytic observational study as its research method. Samples were taken from Pathology Anatomy Laboratory, and the medical record data of lung cancer patients in Ulin General Hospital Banjarmasin from 2017 to 2018. Male lung cancer patients have percentage of 72% with PLR NLR values by sex are not much different p>0.05. 23% of patients were aged ≥ 65 years and 77% were aged £ 65 years with value p>0.05. Adenocarcinoma reaches 65% with p>0.05. Most metastases are 44% pleural effusion with value p>0.05. Percentage of advanced stage is 90% with a higher PLR NLR value at the end stage. There is a meaningful relationship of NLR with lung cancer stage p<0.05, but no relantionship with PLR p>0.05. PRL and NRL are increased at advanced stage. NRL and PRL did not differ significantly based on age, sex and histology of lung cancer. Keywords: Platelet-to-lympho­cyte ratio (PLR), Neutrophil-to-lymphocyte ratio (NLR), lung cancer

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.

Coagulation And Fibrinolysis

Lung cancer has commonly been associated with to both clinical problems of thromboembolism and to biological alterations in -coagulation and fibrinolysis.We evaluated some coagulation and fibrinolytic parameters of the plasmatic coagulation and fibrinolytic system (Fibrinopeptide A (-FPA-) for enzimoimmunoassay, immunological tissue plasminogen activator (t-PA) for enzimoimmunoassay, functional (t-PA) for -chromogenic substrate and functional t-PAinhibitor (PAI) in 40 non-operable lung cancer patients (Table I) comprising 39 males and one female, aged 45 to 67 (average 59). The results are compared with those from a control group of 20 healthy male volun-ters aged 32 to 58 (average 48).Table II shows the results obtained (mean ± SD) for the parameters found to be significantly different to those of the control group. An increase is seen in the levels of FPA, functional t-PA and PAI in the lung cancer group. In the case of the extensive -lung tumor patients, FPAfpa and t-PA levels are significantly higher than for the group of locally advanced neoplasmas.The plasma of lung cancer patients therefore shows fibrinolytic alterations and an increase in thromboplastin activity.

<p class="Abstract">It was aimed to explore the expression level of miRNA-486 and miRNA-499 in the plasma of lung cancer patients and analysis their differences in expre-ssion. The expression level of both miRNA-486 and miRNA-499 in the plasma of non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) were lower than that of the control group (p&lt;0.05) and the decrease was more obvious in NSCLC. Compare with the miRNA-499，expression quantity in NSCLC patients plasma. There was statistical significance difference (p&lt;0.05) between III～Ⅳstage and I～II stage. The expression quantity of miRNA in plasma of patients with extensive-stage SCLC was lower than that of patients with limited-stage SCLC (p&lt;0.05). The sensitivity and specificity of plasms miRNA-486 respectively were 88.5% and 83.3%. The expression of miRNA-499 and miRNA-486 in lung cancer patients were up-regulated, and might be closely related to the occurrence and prognosis of lung cancer, and might be used as potential screening and prognosis index for lung cancer.</p><p> </p>

Abstract Objective The aim of this study was to explore the safe and effective method of expectoration in the preoperative period of patients with lung cancer resection and to promote the rehabilitation of patients. Methods A total of 100 cases of lung cancer patients undergoing elective surgery were divided into the observation group and the control group, with 50 cases in each group. The control group was treated with vibration expectoration vest for expectoration during the perioperative period, and the observation group was treated with respiratory function exerciser that has expectoration function in the perioperative period, three times a day, and the effect was evaluated after 5 days. Results The number of patients in the observation group after the first expectoration time was significantly less than that of the control group (P<0.001). Pain score, pulmonary atelectasis, and pulmonary infection rate of the observation group were significantly lower than those of the control group; the hospitalization time was significantly shorter than that of the control group; and the difference was statistically significant (P<0.05). Conclusions Lobectomy for lung cancer patients with perioperative respiratory training for respiratory function exercise, compared with conventional methods, is helpful for postoperative expectoration and to reduce the incidence of adverse events.

e19072 Background: The gene expression profile in peripheral blood samples from lung cancer patients is a potential predictor to treatment response. Methods: The study has been developed using 10 healthy volunteers as the control group and 10 lung cancer patients (stage IV). Written informed consent was obtained being the protocol approved by the local Clinical Research and Ethics Committee. Peripheral blood samples were obtained from lung cancer patients before (T0) and after treatment (T15d). RNA from peripheral blood samples was extracted and purified selecting 28S/18S ratios>1.5 to obtain cDNA and cRNA for hybridization of the 20,000 genes included in Human 20K CodeLink. An array from each participant was obtained in duplicate. For each array, 2 μg of cRNA was compared to 2 μg of healthy cRNA.. Significant genes were found using Significance Analysis of Microarrays which uses repeated permutations of the data. Results: The selected genes were expressed >3-fold with a false discovery rate =0.05. Before treatment (T0) when patients were compared to healthy volunteers there was an increase in the expression of: histone 1 H4c, transforming growth factor beta 2, endothelial cell growth factor 1 (platelet-derived), glucose-6-phosphatase catalytic 2, Relaxin 3 receptor 1, Insulin-like growth factor binding protein 2, RAS-like family 11 member B, and ELK4. After treatment (T15d), when each lung cancer patient's results were compared to their own before treatment results (T0), there was an increase in the expression of: Bcl2, myosin light polypeptide 4; interferon alpha-inducible protein 27; interferon gamma receptor 1; RASSF5, ARHGEF6, IGFBP5, tumor protein p53 inducible nuclear protein 1, peroxisome proliferative activated receptor gamma. Conclusions: The data presented identifies biologically relevant over-expressed genes in lung cancer. A validation of these results and the analysis of the genes that identify patients who will respond positively to erlotinib treatment is being carried out. No significant financial relationships to disclose.
