A Delphi Method Comfort Status Scale for Patients With Lung Cancer After Thoracoscopic Surgery.

PURPOSE: To construct the comfort status scale for patients with lung cancer after thoracoscopic surgery. DESIGN: Delphi method inquiry to 15 clinical and nursing experts. METHODS: On the basis of the comfort status scale and the subjective experience and objective symptoms of patients with lung cancer after thoracoscopic surgery, the relevant literature was consulted, semistructured interviews and group discussions were conducted, the pool of items of the postoperative comfort status scale for patients with lung cancer was initially formed, and the postoperative comfort status scale for patients with lung cancer was finally established. FINDINGS: The positive coefficient of experts was 100%, the coefficient of authority was 0.92 and 0.93, and the Kendal's W was 0.257 and 0.298, the degree of coordination of expert opinions was statistically significant (P < .05). Finally, a total of 28 items in four dimensions were formed to assess the postoperative comfort status of patients with lung cancer after thoracoscopic surgery. CONCLUSIONS: The Delphi method-based comfort status scale for patients with lung cancer after thoracoscopic surgery is scientific and reliable, and can provide a quantitative basis for the evaluation of the comfort status of patients after lung cancer thoracoscopic surgery, to further provide individual comfort care measures.

Comparison of non-intubated and intubated video-assisted thoracoscopic surgeries of major pulmonary resections for lung cancer-a meta-analysis.

OBJECTIVE: The aim of this study was to compare the safety feasibility and safety feasibility of non-intubated (NIVATS) and intubated video-assisted thoracoscopic surgeries (IVATS) during major pulmonary resections. METHODS: A meta-analysis of eight studies was conducted to compare the real effects of two lobectomy or segmentectomy approaches during major pulmonary resections. RESULTS: Results showed that the patients using NIVATS had a greatly shorter hospital stay and chest-tube placement time (weighted mean difference (WMD): - 1.04 days; 95% CI - 1.50 to - 0.58; P < 0.01) WMD - 0.71 days; 95% confidence interval (CI), - 1.08 to - 0.34; P < 0.01, respectively) while compared to those with IVATS. There were no significant differences in postoperative complication rate, surgical duration, and the number of dissected lymph nodes. However, through the analysis of highly selected patients with lung cancer in early stage, the rate of postoperative complication in the NIVATS group was lower than that in the IVATS group [odds ratio (OR) 0.44; 95% CI 0.21-0.92; P = 0.03, I2 = 0%]. CONCLUSIONS: Although the comparable postoperative complication rate was observed for major thoracic surgery in two surgical procedures, the NIVATS method could significantly shorten the hospitalized stay and chest-tube placement time compared with IVATS. Therefore, for highly selected patients, NIVATS is regarded as a safe and technically feasible procedure for major thoracic surgery. The assessment of the safety and feasibility for patients undergoing NIVATS needs further multi-center prospective clinical trials.

Prognostic role of platelet to lymphocyte ratio in non-small cell lung cancers: A meta-analysis including 3,720 patients.

Platelet to lymphocyte ratio (PLR) was recently reported as a useful index in predicting the prognosis of lung cancer. However, the prognostic role of PLR in lung cancer remains controversial. The aim of this study was to evaluate the association between PLR and clinical outcome of lung cancer patients through a meta-analysis. Relevant literatures were retrieved from PubMed, Ovid, the Cochrane Library and Web of Science databases. Meta-analysis was performed using hazard ratio (HR) and 95% confidence intervals (CIs) as effect measures. A total of 5,314 patients from 13 studies were finally enrolled in the meta-analysis. The summary results showed that elevated PLR predicted poorer overall survival (OS) (HR: 1.526, 95%CI: 1.268-1.836, p < 0.001) in patients with lung cancer and OS (HR: 1.631, 95%CI: 1.447-1.837, p < 0.001) in patients with nonsmall cell lung cancer (NSCLC). Subgroup analysis revealed that increased PLR was also associated with poor OS in NSCLC treated by surgical resection (HR: 1.884, 95%CI: 1.308-2.714, P < 0.001) and non-surgery (HR: 1.570, 95%CI: 1.323-1.863, P < 0.001). In addition, PLR Cut-off value ≤ 160 (HR: 1.506, 95%CI: 1.292-1.756, P < 0.001) and PLR Cut-off value>160 (HR: 1.842, 95%CI: 1.523-2.228, P < 0.001). In contrast, elevated PLR was not associated with OS (HR: 1.117, 95%CI: 0.796-1.569, P > 0.05) in patients with small cell lung cancer (SCLC).This meta-analysis result suggested that elevated PLR might be a predicative factor of poor prognosis for NSCLC patients.

Reliability and validity analyses of the postoperative comfort scale for patients with lung cancer undergoing endoscopic surgery and an evaluation of patient comfort.

BACKGROUND: Lung cancer is one of the most common malignant tumours that threaten human health globally. Radical resection under thoracoscopic guidance has been accepted as the major therapeutic option for treating lung cancer clinically. However, the procedure still has some adverse impacts on the comfort of patients following thoracoscopic surgery. OBJECTIVE: To analyse the reliability and validity of the postoperative comfort scale for patients with lung cancer undergoing endoscopic surgery and to evaluate patient comfort. METHODS: With 210 patients with lung cancer undergoing endoscopic surgery as the participants, this study was performed to assess the reliability and validity of the postoperative comfort scale for patients with lung cancer undergoing endoscopic surgery, with the assessment performed by eight experts. RESULTS: The postoperative comfort scale included 28 items and consisted of four dimensions (physiological, psychological, socio-cultural and environmental). The total Cronbach's alpha coefficient of the scale was 0.851, and the split-half reliability coefficient was 0.875. Meanwhile, the content validity index (CVI) was 0.875∼1, and the scale-level average CVI was 0.99. The Chi-square/degree-of-freedom ratio of construct validity was 2.844, suggesting a good model-fitting. Furthermore, the overall average score of patient comfort was 3.72 ± 0.57, with scores ranging between 3.59 ± 0.71 and 3.83 ± 1.06 across all four dimensions, with the lowest score in the physiological dimension. CONCLUSION: The postoperative comfort scale has good reliability and validity and can be applied for the postoperative comfort assessment of patients undergoing endoscopic surgery for lung cancer. Overall, the degree of patient comfort in this assessment was moderate, meaning targeted measures may be required to further improve patient comfort, especially in the physiological dimension.

Posterior mediastinal leiomyosarcoma: Case report and literature review.

BACKGROUND: Posterior mediastinal leiomyosarcoma is an extremely rare malignant mesenchymal tumor with no special clinical symptoms, which is easily confused with some common tumors in the posterior mediastinum, affecting the accuracy of the first diagnosis by clinicians and delaying the treatment of patients. CASE SUMMARY: We report a 59-year-old woman with a space-occupying lesion in the posterior mediastinum. The patient was mistakenly diagnosed with lumbar muscle or vertebral body lesions due to chest and back pain and underwent conservative treatment, but her symptoms did not improve significantly and she gradually developed pain in both lower limbs. Chest computed tomography (CT) scan indicated the left lower lung paraspinal space and underwent standard single-aperture video-assisted thoracoscopic surgery (VATS), which was pathologically confirmed as posterior mediastinal leiomyosarcoma. CONCLUSION: Complete surgical resection of posterior mediastinal leiomyosarcoma can achieve good clinical results.

[Intravascular Large B-cell Lymphoma Presenting with Lung Adenocarcinoma:
A Case Report and Literature Review].

Intravascular large B-cell lymphoma (IVLBCL) is an aggressive extranodal large B-cell lymphoma, cocurrence in the same organ with other malignancies is very rare, especially in the lung. Here, we report a rare case of lung adenocarcinoma with IVLBCL. The patient was admitted to the hospital due to diarrhea associated with fever and cough. A computed tomography (CT) scan of the chest showed an irregular patchy high-density shadow in the upper lobe of the right lung with ground-glass opacity at the margin. After admission, the patient was given anti-infection treatment, but still had intermittent low fever (up to 37.5 °C). The pathological diagnosis of percutaneous lung biopsy (PLB) was lepidic-predominant adenocarcinoma with local infiltration, which was proved to be invasive nonmucinous adenocarcinoma of the lung with IVLBCL after surgery. This paper analyzed the clinicopathological characteristics and reviewed the relevant literature to improve the knowledge of clinicians and pathologists and avoid missed diagnosis or misdiagnosis.

The correlation between KRAS and TP53 gene mutations and early growth of pulmonary nodules.

PURPOSE: The purpose of this study is to investigate whether gene mutations can lead to the growth of malignant pulmonary nodules. METHODS: Retrospective analysis was conducted on patients with pulmonary nodules at Hebei Provincial People's Hospital, collecting basic clinical information such as gender, age, BMI, and hematological indicators. According to the inclusion and exclusion criteria, 85 patients with malignant pulmonary nodules were selected for screening, and gene mutation testing was performed on all patient tissues to explore the relationship between gene mutations and the growth of malignant pulmonary nodules. RESULTS: There is a correlation between KRAS and TP53 gene mutations and the growth of pulmonary nodules (P < 0.05), while there is a correlation between KRAS and TP53 gene mutations and the growth of pulmonary nodules in the subgroup of invasive malignant pulmonary nodules (P < 0.05). CONCLUSION: Mutations in the TP53 gene can lead to the growth of malignant pulmonary nodules and are correlated with the degree of invasion of malignant pulmonary nodules.

Prognostic significance of Memorial Sloan-Kettering prognostic score in small-cell lung cancer patients.

Aim: To assess the potential factors with predictive value for survival in small-cell lung cancer (SCLC) patients and to develop a nomogram prediction model. Patients & methods: We retrospectively screened and analyzed patients with pathologically confirmed SCLC from April 2015 to December 2021. Results: A total of 167 patients with SCLC were included. According to the Memorial Sloan-Kettering prognostic score (MPS), patients were divided into three groups: group 0 (n = 65), group 1 (n = 69) and group 2 (n = 33). The multivariate analysis showed that MPS was an independent prognostic factor for progression-free and overall survival in SCLC patients (p < 0.05). The nomogram showed that MPS was the most influential factor for overall survival. Conclusion: MPS is an independent prognostic factor for overall and progression-free survival in SCLC patients and performed better than other indicators used in this study.

Right upper lobe segmentectomy and subsegmentectomy guided by classification pattern of peripheral segmental veins.

Background: Studies have analyzed the simplified branching pattern of peripheral segmental veins and developed a standardized approach for intersegmental vein identification in the right upper lobe (RUL). However, the identification approach of intersubsegmental veins has not been reported. This study aimed to supplement the identification approach of intersubsegmental veins and the classification pattern of peripheral segmental veins by using three-dimensional computed tomography bronchography and angiography (3D-CTBA). Materials and methods: A total of 600 patients with ground glass opacity (GGO) who had undergone 3D-CTBA preoperatively at Hebei General Hospital between September 2020 and September 2022 were used for the retrospective study. We reviewed the anatomical variations of RUL veins in these patients using 3D-CTBA images. Results: According to the anatomical position, the peripheral segmental veins structures of RUL were classified into five categories: "Iab type of anterior with central vein" (256/600, 42.7%), "Ib type of anterior with central vein" (166/600, 27.7%), "Central vein type" (38/600, 6.3%), "Anterior vein type" (81/600, 13.5%), "Right top pulmonary vein type" (57/600, 9.5%). The approach for intersegmental vein and intersubsegmental veins identification was divided into five types: anterior approach, posterobronchial approach, central vein approach, V2t approach, and intermediate bronchus posterior surface approach. Conclusions: The classification pattern of peripheral segmental veins should find wide application. Further, approaches identifying intersegmental veins and intersubsegmental veins may help thoracic surgeons perform safe and accurate RUL segmentectomy.

Tumor blood vessel in 3D reconstruction CT imaging as an risk indicator for growth of pulmonary nodule with ground-glass opacity.

OBJECTIVE: Despite the vital role of blood perfusion in tumor progression, in patients with persistent pulmonary nodule with ground-glass opacity (GGO) is still unclear. This study aims to investigate the relationship between tumor blood vessel and the growth of persistent malignant pulmonary nodules with ground-glass opacity (GGO). METHODS: We collected 116 cases with persistent malignant pulmonary nodules, including 62 patients as stable versus 54 patients in the growth group, from 2017 to 2021. Three statistical methods of logistic regression model, Kaplan-Meier analysis regression analysis were used to explore the potential risk factors for growth of malignant pulmonary nodules with GGO. RESULTS: Multivariate variables logistic regression analysis and Kaplan-Meier analysis identified that tumor blood vessel diameter (p = 0.013) was an significant risk factor in the growth of nodules and Cut-off value of tumor blood vessel diameter was 0.9 mm with its specificity 82.3% and sensitivity 66.7%.While in subgroup analysis, for the GGO CTR < 0.5[C(the maximum diameter of consolidation in tumor)/T(the maximum diameter of the whole tumor including GGO) ratio], tumor blood vessel diameter (p = 0.027) was important during the growing processes of nodules. CONCLUSIONS: The tumor blood vessel diameter of GGO lesion was closely associated with the growth of malignant pulmonary nodules. The results of this study would provide evidence for effective follow-up strategies for pulmonary nodule screening.

Predicting pleural invasion of invasive lung adenocarcinoma in the adjacent pleura by imaging histology.

The aim of the present study was to develop a non-invasive method based on histological imaging and clinical features for predicting the preoperative status of visceral pleural invasion (VPI) in patients with lung adenocarcinoma (LUAD) located near the pleura. VPI is associated with a worse prognosis of LUAD; therefore, early and accurate detection is critical for effective treatment planning. A total of 112 patients with preoperative computed tomography presentation of adjacent pleura and postoperative pathological findings confirmed as invasive LUAD were retrospectively enrolled. Clinical and histological imaging features were combined to develop a preoperative VPI prediction model and validate the model's efficacy. Finally, a nomogram for predicting LUAD was established and validated using a logistic regression algorithm. Both the clinical signature and radiomics signature (Rad signature) exhibited a perfect fit in the training cohort. The clinical signature was overfitted in the testing cohort, whereas the Rad signature showed a good fit. To combine clinical and radiomics signatures for optimal performance, a nomogram was created using the logistic regression algorithm. The results indicated that this approach had the highest predictive performance, with an area under the curve of 0.957 for the clinical signature and 0.900 for the Rad signature. In conclusion, histological imaging and clinical features can be combined in columnar maps to predict the preoperative VPI status of patients with adjacent pleural infiltrative lung carcinoma.

Clinical Significance of Preoperative Naples Prognostic Score in Patients With Non-Small Cell Lung Cancer.

Background: Naples Prognostic Score (NPS) is a novel score based on inflammatory-nutritional indicators. We aimed to analyze the prognostic value of the Naples Prognostic Score in non-small cell lung cancer (NSCLC) patients following surgery. Methods: A total of 319 NSCLCpatients following surgery were analyzed in the retrospective cohort study. We analyzed the predictive value of Naples Prognostic Score for overall survival and recurrence-free survival in postoperative non-small cell lung cancer patients by using Kaplan-Meier survival curves and multivariate Cox regression analysis. At the same time, the time-dependent ROC and the area under curves were also created to compare the accuracy of different scoring systems. Results: According to NPS, we divided all patients into 3 groups，120 patients were divided into group 0, 161 patients were divided into group 1, and 38 patients were divided into group 2. The median survival time for all patients is 32 months, and the median survival times for different groups were 35 months, 31 months, and 28 months, respectively. The overall survival and recurrence-free survival survival curves of different groups were significantly different (both P < .05), and patients in the higher NPS groups had a disappointing prognosis. NPS may be an independent prognostic factor for overall survival and recurrence-free survival, according to the results of multivariate analysis (both P < .05). The area under curve showed that the accuracy of the NPS was significantly better than other score systems. Conclusions: The NPS is closely related to the long-term survival prognosis of patients with NSCLC, especially in stage III patients.

Prognostic significance of TG/HDL-C and non-HDL-C/HDL-C ratios in patients with non-small cell lung cancer: a retrospective study.

OBJECTIVE: Lung cancer is a malignancy with high a mortality rate that threatens human health. This study is aimed to explore the correlation among the triglyceride/high-density lipoprotein ratio (TG/HDL-C), non-high-density lipoprotein/high-density lipoprotein ratio (non-HDL-C/HDL-C) and survival of patients with non-small cell lung cancer (NSCLC) undergoing video-associated thoracic surgery (VATS). METHODS: This retrospective study analyzed 284 patients with NSCLC who underwent VATS at Hebei General Hospital, Shijiazhuang, China. The time-dependent receiver operating characteristic curve was used to determine the optimal cutoff value and evaluate the area under the curve. Kaplan-Meier and Cox regression analyses were performed to determine the prognostic effect. RESULTS: The median overall survival (OS) was 46 months. Patients with low TG/HDL-C and low non-HDL-C/HDL-C had a longer OS. The low non-HDL-C/HDL-C group showed a longer mean survival time (59.00 vs. 52.35 months). Multivariate analysis revealed that TG/HDL-C and non-HDL-C/HDL-C were significantly correlated with OS. CONCLUSIONS: TG/HDL-C and non-HDL-C/HDL-C are associated with the prognosis of patients with NSCLC who received VATS. Preoperative serum TG/HDL-C and non-HDL-C/HDL-C may be effective independent prognostic factors for predicting the outcomes of patients with NSCLC.

Naples Prognostic Score is an Independent Prognostic Factor in Patients with Small Cell Lung Cancer and Nomogram Predictive Model Established.

Background: The routine clinical nutritional and inflammatory indicators such as serum albumin, total cholesterol and lymphocytes have been widely investigated in the prognosis of small cell lung cancer (SCLC). The Naples prognostic score (NPS), based on nutritional and inflammatory status, has been identified as a prognostic impactor in several malignancies. However, the prognostic role of NPS in SCLC has not been elucidated. This study aims to evaluate the prognostic effect of NPS in SCLC patients. Patients and Methods: Patients with SCLC were recruited at Hebei General Hospital between April 2015 and August 2021. Pretreatment clinical and laboratory data were obtained. Participants were assigned into three groups according to NPS (group 0: NPS=0, group 1: NPS=1 or 2, group 2: NPS=3 or 4). Kaplan-Meier and Cox regression analysis were performed to assess the prognostic significance of NPS. The RMS package in R software was used to draw the nomogram predictive model. Results: A total of 128 patients were enrolled. The median progression-free survival (PFS) and overall survival (OS) was 7.2 and 12.3 months, respectively. The median PFS and OS was 12.3 vs 19.8 months, 7.6 vs 14.1 months and 6.0 vs 8.45 months for the three groups respectively. There were significant differences in both OS and FPS among the three groups. Survival analysis showed that NPS was significantly correlated with both OS and PFS (P<0.05). Lower NPS is associated with longer OS and PFS. Multivariate analysis showed that NPS has an independent prognostic impact on OS (P<0.05). The nomogram predictive model showed that NPS has good predictive power for survival rates. Conclusion: NPS is an independent prognostic factor for OS in SCLC patients. Low NPS may predict longer OS. Therefore NPS plays a vital role in the nomogram predictive model of survival rates in SCLC patients.

Correlation and significance of COX-2, Ki67, VEGF and other immune indexes with the growth of malignant pulmonary nodules.

OBJECTIVE: This study intends to explore the factors affecting the growth of pulmonary nodules in the natural process by immunohistochemical method. METHODS: 40 cases of pulmonary nodules followed up for more than 3 years were divided into growth group (n = 20) and stable group (n = 20). The expressions of cyclooxygenase-2 (COX-2), Ki67, vascular endothelial growth factor (VEGF), CD44V6, epidermal growth factor receptor (EGFR), double microsome 2 (MDM2) and transforming growth factor (TGF)-ß1 in pulmonary nodules were detected by immunohistochemical method so as to explore the relationship between it and the growth of pulmonary nodules. RESULTS: Compared with stable pulmonary nodules, the positive rates of COX-2, Ki67 and VEGF in the growth group were 85%, 80% and 55%, respectively. There was significant difference between the stable group and the growth group (P < 0.05). The correlation between other indexes and the growth of pulmonary nodules was not statistically significant (Pcd44v6 = 0.104;PEGFR = 0.337; PMDM2 = 0.49; PTGF-ß1 = 0.141). In the subgroup of patients with non-invasive lung cancer, there was a correlation between VEGF and the growth of pulmonary nodules (P < 0.05). CONCLUSION: The high expression of COX-2, Ki67 and VEGF proteins may be significantly related to the growth of pulmonary nodules, and VEGF may be an important factor affecting the growth of malignant pulmonary nodules. This study intends to provide a research direction for further searching for the essential causes of the growth of pulmonary nodules.

The prognostic value of the advanced lung cancer inflammation index (ALI) for patients with neuroblastoma.

OBJECTIVE: The advanced lung cancer inflammation index (ALI) can predict the survival of patients with lung cancer and other malignancies. However, the prognostic significance of ALI in neuroblastoma has not been reported. This study aimed to evaluate the correlation between ALI and neuroblastoma patient prognosis. METHODS: We retrospectively analyzed the data of 72 neuroblastoma patients treated between January 2014 and August 2020. ALI calculation: Body mass index (BMI) × serum albumin (ALB)/neutrophil-to-lymphocyte ratio (NLR). The optimal cutoff points of prognostic biomarkers were determined by generating receiver operating characteristic (ROC) curves. According to the cutoff value, the patients were categorized into low or high ALI groups. The chi-square test was used to compare clinical parameters between the two groups. Potential prognostic factors associated with overall survival (OS) were assessed using Kaplan-Meier and Cox regression analyses. RESULTS: The optimal cutoff value of ALI was 49.17. The low ALI group showed more severe clinical characteristics and poorer survival rates. Univariate and multivariate Cox analyses suggested that ALI and the International Neuroblastoma Staging System (INSS) stage were independent prognostic factors for neuroblastoma patients. CONCLUSIONS: Low ALI is associated with poor prognosis in neuroblastoma patients. ALI may be an independent prognostic biomarker for neuroblastoma.

The advanced lung cancer inflammation index predicts outcomes of patients with non-small cell lung cancer following video-assisted thoracic surgery.

OBJECTIVE: The advanced lung cancer inflammation index (ALI) predicts overall survival (OS) in patients with advanced lung cancer. However, few studies have tested ALI's prognostic effect in patients with non-small cell lung cancer (NSCLC) following video-assisted thoracic surgery (VATS), especially patients at stage III. This study investigated the relationship between ALI and outcomes of patients with NSCLC following VATS. METHODS: We retrospectively examined 339 patients with NSCLC who underwent VATS at Hebei General Hospital, China. Preoperative clinical and laboratory parameters were collected and analyzed. Optimal cutoff values of potential prognostic factors, including ALI, were determined. Kaplan-Meier and Cox regression analyses were used to determine each factor's prognostic value. RESULTS: The median OS was 31 months. The optimal cutoff value for ALI was 41.20. Patients with high ALI (≥41.20) displayed increased OS (33.87 vs. 30.24 months), higher survival rates, and milder clinical characteristics. Univariate and multivariate analyses showed a significant correlation between ALI and the prognosis of patients with NSCLC, including those at stage IIIA, who underwent VATS. CONCLUSIONS: Low ALI correlated with poor outcomes in patients with NSCLC following VATS. Preoperative ALI might be a potential prognostic biomarker for patients with NSCLC following VATS, including patients at stage IIIA.

Role of circulating tumor cells in diagnosis of lung cancer: a systematic review and meta-analysis.

OBJECTIVE: We systematically reviewed the literature relating to the diagnostic accuracy of circulating tumor cells (CTCs) for the clinical determination of lung cancer. METHODS: This meta-analysis aimed to evaluate the diagnostic accuracy of CTCs for the clinical determination of lung cancer. The PubMed, Embase, Cochrane Library, and Web of Science databases were searched for relevant studies up to 31 May 2020. The numbers of patients with true positive, false positive, false negative, and true negative results were extracted from each individual study. Pooled sensitivity, specificity, and area under the curve values were calculated with 95% confidence intervals (CI). RESULTS: Twenty-one studies with 3997 subjects met the inclusion criteria. The overall diagnostic accuracy was assessed. The pooled sensitivity and specificity were 0.72 (95%CI: 0.65-0.79) and 0.96 (95%CI: 0.91-0.98), respectively, and the pooled positive and negative likelihood ratios were 16.86 (95%CI: 7.65-37.12) and 0.29 (95%CI: 0.23-0.37), respectively. The combined diagnostic odds ratio was 58.12 (95%CI: 24.82-136.09). CONCLUSION: This meta-analysis indicated that CTCs had good diagnostic value for detecting lung cancer.

Neutrophil-Lymphocyte Ratio as a Predictive Factor of Growing Malignant Pulmonary Ground-glass Opacity.

BACKGROUND: The object of the study was to elucidate the relationship between the neutrophil-lymphocyte ratio (NLR) and the growth of pulmonary ground-glass opacity (GGO) in stage IA lung adenocarcinoma. METHODS: All patients with GGO following surgical procedures were enrolled, with the time of follow-up and the variation tendency of GGO recorded. Meanwhile, laboratory parameters, age, gender, smoking history, histology, tumor size, and stage were recorded. Logistic regression was used to evaluate the value of NLR and the cutoff value was calculated by SPSS 22.0. RESULTS: In the whole cohort, 30 cases of growing GGO and 43 cases of stable GGO undergoing surgical procedures were diagnosed as lung adenocarcinoma. There was significant statistical difference between the two groups. Multivariable analysis showed that NLR could predict the GGOs with growth (odds ratio 5.198, 95% confidence interval (95%CI: 1.583-14.581, P=0.002). Receiver operating characteristics analysis for NLR showed the optimal cutoff value of 2.38, with a sensitivity of 60.0% and specificity of 81.4%. CONCLUSION: Our study demonstrated that the NLR appeared to have value as a promising clinical predictor of GGOs with growth. Further studies are needed to confirm this conclusion.

Advanced Lung Cancer Inflammation Index is a Prognostic Factor of Patients with Small-Cell Lung Cancer Following Surgical Resection.

PURPOSE: Advanced lung cancer inflammation index (ALI) has been shown to predict overall survival (OS) in advanced non small-cell lung cancer (NSCLC), small-cell lung cancer (SCLC) and operable NSCLC. However, there were no studies of the correlation between ALI and operable SCLC. Therefore, this study is aimed to explore the relationship between ALI and the prognosis of operable SCLC. PATIENTS AND METHODS: A total of 48 patients with SCLC who underwent surgery at Hebei General Hospital and Zigong First People's Hospital were screened between 2016 and 2020. ALI was calculated as follows: body mass index (BMI, kg/m2)×serum albumin (ALB, g/dL)/neutrophil to lymphocyte ratio (NLR). Receiver operating characteristic (ROC) curve was used to determine the optimal cutoff value of ALI. Patients were divided into two groups according to the cutoff point of ALI: low ALI group with ALI<48.2 and high ALI group with ALI≥48.2. Kaplan-Meier and Cox regression analysis were performed to assess the potential prognostic factors associated with OS. RESULTS: The optimal cutoff value of ALI was determined as 48.2. The low ALI group displayed more adverse clinical characteristics and poorer survival rates. Multivariate analysis revealed that ALI and Charlson comorbidity index (CCI) were significantly correlated with OS. CONCLUSION: Low ALI was correlated with poor prognosis in patients with SCLC who underwent surgery. Preoperative ALI might serve as a potential prognostic marker for patients with operable SCLC.
