P5‐124: Analysis of chemotherapy history and absolute neutrophil count to antibody antimannan in lung cancer patients with candidiasis

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.

Lung Cancer Patients

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.
