    The Prognostic Value of the Novel Global Immune-Nutrition-Inflammation Index (GINI) in Stage IIIC Non-Small Cell Lung Cancer Patients Treated with Concurrent Chemoradiotherapy
    (2023) Topkan, Erkan; Selek, Ugur; Pehlivan, Berrin; Kucuk, Ahmet; Ozturk, Duriye; Ozdemir, Beyza Sirin; Besen, Ali Ayberk; Mertsoylu, Huseyin; 0000-0001-8120-7123; 37760482; AAG-2213-2021
    Simple Summary: We investigated the prognostic significance of the newly created Global Immune-Nutrition-Inflammation Index (GINI) in IIIC non-small cell lung cancer (NSCLC) patients who received definitive concurrent chemoradiotherapy (CCRT). A total of 802 newly diagnosed stage IIIC NSCLC patients were included. The optimal pre-CCRT GINI cutoff was 1562 (area under the curve: 76.1%; sensitivity: 72.4%; specificity: 68.2%; Youden index: 0.406). GINI >= 1562 was associated with significantly shorter median locoregional progression-free (p < 0.001), progression-free (p < 0.001), and overall survival (p < 0.001) than GINI < 1562. For each survival endpoint, the association between GINI and survival outcomes appeared independent of other confounding variables (p < 0.05 for each). The novel GINI index effectively stratified patients with stage IIIC NSCLSC into two distinct subgroups, demonstrating significant differences in both median and long-term survival rates. Background: We sought to determine the prognostic value of the newly developed Global Immune-Nutrition-Inflammation Index (GINI) in patients with stage IIIC non-small cell lung cancer (NSCLC) who underwent definitive concurrent chemoradiotherapy (CCRT). Methods: This study was conducted on a cohort of 802 newly diagnosed stage IIIC NSCLC patients who underwent CCRT. The novel GINI created first here was defined as follows: GINI = [C-reactive protein x Platelets x Monocytes x Neutrophils] divided by [Albumin x Lymphocytes]. The receiver operating characteristic (ROC) curve analysis was used to determine the optimal pre-CCRT GINI cut-off value that substantially interacts with the locoregional progression-free (LRPFS), progression-free (PFS), and overall survival (OS). Results: The optimal pre-CCRT GINI cutoff was 1562 (AUC: 76.1%; sensitivity: 72.4%; specificity: 68.2%; Youden index: 0.406). Patients presenting with a GINI >= 1562 had substantially shorter median LRPFS (13.3 vs. 18.4 months; p < 0.001), PFS (10.2 vs. 14.3 months; p < 0.001), and OS (19.1 vs. 37.8 months; p < 0.001) durations than those with a GINI < 1562. Results of the multivariate analysis revealed that the pre-CCRT GINI >= 1562 (vs. <1562), T4 tumor (vs. T3), and receiving only 1 cycle of concurrent chemotherapy (vs. 2-3 cycles) were the factors independently associated with poorer LRPS (p < 0.05 for each), PFS (p < 0.05 for each), and OS (p < 0.05 for each). Conclusion: The newly developed GINI index efficiently divided the stage IIIC NSCLSC patients into two subgroups with substantially different median and long-term survival outcomes.

    The Clinicopathological and Survival Differences Between Never and Ever Smokers with Non-Small Cell Lung Cancer

    Purpose: Cigarette smoking was regarded as the most important carcinogenic factor of lung cancer, yet in recent years lung cancer in never-smokers is an increasingly prominent public health issue. The aim of this study was to assess the epidemiological and clinicopathological characteristics of never-smoker patients with non small cell lung cancer (NSCLC), focusing on clinical risk factors and survival. Methods: We retrospectively analyzed 290 NSCLC patients who presented between 2006 and 2011. Differences in clinical features and survival between never- and ever-smoker patients were analyzed. Student's t-test and Mann-Whitney U-test were used to assess the significance of the variables between the groups. Survival curves were calculated using Kaplan-Meier method. Hazard ratio (HR) for death and its 95% confidence interval (CI) were calculated by Cox regression analysis. Results: There were 243 (83.8%) ever-smokers and 47 (16.2%) never-smokers. In never-smokers females predominated (80.9%) as well as patients with adenocarcinomas (78.7%). At the time of analysis 143 (49.3%) patients had died. The 5-year overall survival (OS) rates were not significantly different between never- and ever-smokers (p=0.410). The median OS of all patients was 26 months (95% CI: 16.8-35.2). The median OS was 23 months (95% CI: 11.8-34.2)for never-smokers and 30 months (95% CI: 19.7-40.3) forever-smokers (p=0.410). Never-smokers tended to present with more advanced disease than ever-smokers (p<0.004) and also with more advanced age (p<0.001). The HR for death increased with poorer Eastern Cooperative Oncology Group (ECOG) performance status (PS) (ECOG 2-3), advanced stage (stage 3-4) and untreated patients. Slightly lower risk for death was registered in patients with adenocarcinoma vs those with squamous cell carcinoma (S CC). Conclusion: Although no difference in survival was seen, definite epidemiologic differences do exist between never-smokers and ever-smokers patients with NSCLC. Future efforts should focus on the underlying biological differences, and on identifying potential non-tobacco related risk factors in order to improve treatment strategies for these two groups of NSCLC patients.
