Glutathione inhibits lung cancer development by reducing interleukin-6 expression and reversing the Warburg effect

Reduced glutathione (GSH) is widely used as an antioxidant in clinical practice, but whether GSH affects the development of early lung cancer remains unclear. Herein, we investigated the mechanism underlying the anticancer effect of GSH in patients with pulmonary nodules. Thirty patients with pulmonary nodules were treated with GSH intravenously for 10 days at a dose of 1.8 g/d, followed by oral administration of the drug at a dose of 0.4 g three times daily for 6 months. The results showed that GSH treatment promoted nodule absorption and reduced the IL-6 level in the peripheral blood of the patients. GSH reduced IL-6 expression in inflammatory BEAS-2B and lung cancer cells and inhibited the proliferation of lung cancer cell lines in vitro. In addition, GSH reduced IL-6 expression by decreasing ROS via down-regulating PI3K/AKT/FoxO pathways. Finally, GSH reversed the Warburg effect, restored mitochondrial function, and reduced the IL-6 expression via PI3K/AKT/FoxO pathways. The in vivo experiment confirmed that GSH inhibited lung cancer growth, improved mitochondrial function, and reduced the IL-6 expression by regulating key enzymes via the PI3K/AKT/FoxO pathway. In conclusion, we uncovered that GSH exerts an unprecedentedly potent anti-cancer effect to prevent the transformation of lung nodules to lung cancer by improving the mitochondrial function and suppressing inflammation via PI3K/AKT/FoxO pathway. This investigation innovatively positions GSH as a potentially safe and efficacious old drug with new uses, inhibiting inflammation and early lung cancer. The use of the drug offers a promising preventive strategy when administered during the early stages of lung cancer.

Case report: MSI-H, EGFR mutation, and ground-glass nodules as diffuse pulmonary hematogenous metastases

Ground-glass nodules (GGNs) are generally considered an early stage of lung cancer. The imaging characteristics and curative efficacy of multiple GGNs as metastases remain unclear. Microsatellite instability-high (MSI-H) is a biomarker for immunotherapy. The therapeutic effect and prognosis for patients with MSI-H and Epidermal Growth Factor Receptor (EGFR)-sensitive mutation stays uncertain. Here, we report a case of a lung adenocarcinoma patient presenting with ground-glass metastases, MSI-H, and EGFR-sensitive mutation and provide clinical data on the efficacy and prognosis. We describe the predictive significance of carcinoembryonic antigen (CEA) for disease progression when there is inconsistency between treatment effectiveness and CEA changes.

Prevalence and Risk Factors of Psychological Distress in Patients With Early-Stage Lung Cancer During Preoperative Period: A Cross-Sectional Study.

This study aims to investigate the prevalence of significant psychological distress and identify risk factors associated with it among early-stage lung cancer patients in the preoperative period. Lung cancer is a major cause of cancer deaths worldwide, with low survival rates and significant psychological distress. While much research has focused on distress in advanced-stage patients, less is known about the prevalence and risk factors of psychological distress in early-stage lung cancer patients before surgery. A cross-sectional study. The study included 427 early-stage lung cancer patients preparing for surgery. Researchers used a study-specific questionnaire to gather general information and employed the Distress Management Screening Measurement, Patient Health Questionnaire-9 and Generalised Anxiety Disorder-7 to assess personal situations and psychological distress levels. Statistical analyses investigated distress across various patient characteristics and examined correlations with anxiety and depression. Binary logistic regression identified significant predictors of psychological distress. The study found that 41.9% of early-stage lung cancer patients experienced significant psychological distress preoperatively, with an average score of 3.31 ± 2.18. Psychological distress was significantly positively correlated with depression (r = 0.474, p < 0.001) and anxiety (r = 0.591, p < 0.001). Significant risk factors for psychological distress included pulmonary nodules (OR = 2.884, 95% CI: 1.496-5.559), smoking history (OR = 2.092, 95% CI: 1.016-4.306) and chronic diseases (OR = 2.013, 95% CI: 1.073-3.776). Early-stage lung cancer patients often experience a high incidence of clinically significant psychological distress during the preoperative period, strongly associated with depression and anxiety. Adverse factors contributing to psychological distress include multiple indeterminate pulmonary nodules, smoking history and concurrent chronic diseases. Routine screening for psychological distress in these patients is recommended, along with personalised interventions and self-management strategies to help alleviate their distress during the perioperative period.

Mini-Invasive Thoracic Surgery for Early-Stage Lung Cancer: Which Is the Surgeon’s Best Approach for Video-Assisted Thoracic Surgery?

Objectives: The choice of the best Video-Assisted Thoracic Surgery (VATS) surgical approach is still debated. Surgeons are often faced with the choice between innovation and self-confidence. The present study reports the experience of a high-volume single institute, comparing data of uni-portal, bi-portal and tri-portal VATS, to find out the safest and most effective mini-invasive approach, leading surgeon’s choice. Methods: Between 2015 and 2022, a total of 210 matched patients underwent VATS lobectomy for early-stage cancer, using uni-portal (fifth intercostal space), bi-portal (seventh space for optic and the fifth), and tri-portal (seventh and the fifth/four) access. Patients were matched for age, BPCO, smoke, comorbidities, lesions (size and staging) to obtain three homogenous groups (A: uni-portal; B: bi-portal; C: tri-portal). The surgeons had comparable expertise. Data were retrospectively collected from institutional database and analyzed. Results: No differences were detected considering time of surgery, length of hospital stay, complications, conversion rate, specific survival, and days of chest tube length of stay. Better results on chest tube removal were described in group A (mean 1.1 days) compared to B (mean 2.6 days) and C (mean 4.7 days); nevertheless, they not statistically significant (p = 0.106). Conclusions: No significant differences among the groups were described, except for the reduction in chest tube permanence in group A. This allows to hypothesize an enhanced recovery after surgery in this group but the different approaches in this series seem to guarantee comparable safety and effectiveness. Considering no superiority of one method above the others, the best suggested approach should be the one for which the surgeon feels more confident.

Optimizing lung cancer surgery in the elderly: sublobar resection versus lobectomy for early-stage non-small cell lung cancer patients aged 80 and above

The optimal surgical approach for elderly patients with early-stage non-small cell lung cancer (NSCLC) remains a topic of debate. A retrospective analysis was conducted on patients who underwent pulmonary resection for early-stage NSCLC at our single institution between January 2018 and December 2022. Propensity score matching was used to balance baseline characteristics between the sublobar resection and lobectomy groups. Perioperative outcomes, pulmonary function recovery, postoperative quality of life, and survival were compared between the two groups. A total of 151 patients were included, with 42 undergoing sublobar resection and 109 undergoing lobectomy. After propensity score matching, baseline characteristics were well-balanced between the two groups. Sublobar resection was associated with shorter operative time (125.83 ± 33.56 min vs. 161.14 ± 61.54 min, p = 0.048), less intraoperative blood loss [65 (30, 75) ml vs. 120 (70, 170) ml, p < 0.001], shorter drainage duration [3 (2, 5) days vs. 5 (3, 6) days, p < 0.001], shorter hospital stay [6 (4, 8) days vs. 10 (7, 13) days, p < 0.001], and fewer postoperative complications (11.9% vs. 47.6%, p < 0.001), compared to lobectomy. Moreover, sublobar resection led to better pulmonary function recovery and higher postoperative quality of life scores, with no significant difference in overall and disease-free survival between the groups. Sublobar resection in patients aged 80 and above with early-stage NSCLC offered comparable oncological outcomes to lobectomy while preserving more lung function and providing better postoperative recovery and long-term quality of life. These findings have important implications for treatment decision-making in elderly NSCLC patients.

Lightweight Advanced Deep Neural Network (DNN) Model for Early-Stage Lung Cancer Detection

Background: Lung cancer, also known as lung carcinoma, has a high mortality rate; however, an early prediction helps to reduce the risk. In the current literature, various approaches have been developed for the prediction of lung carcinoma (at an early stage), but these still have various issues, such as low accuracy, high noise, low contrast, poor recognition rates, and a high false-positive rate, etc. Thus, in this research effort, we have proposed an advanced algorithm and combined two different types of deep neural networks to make it easier to spot lung melanoma in the early phases. Methods: We have used WDSI (weakly supervised dense instance-level lung segmentation) for laborious pixel-level annotations. In addition, we suggested an SS-CL (deep continuous learning-based deep neural network) that can be applied to the labeled and unlabeled data to improve efficiency. This work intends to evaluate potential lightweight, low-memory deep neural net (DNN) designs for image processing. Results: Our experimental results show that, by combining WDSI and LSO segmentation, we can achieve super-sensitive, specific, and accurate early detection of lung cancer. For experiments, we used the lung nodule (LUNA16) dataset, which consists of the patients’ 3D CT scan images. We confirmed that our proposed model is lightweight because it uses less memory. We have compared them with state-of-the-art models named PSNR and SSIM. The efficiency is 32.8% and 0.97, respectively. The proposed lightweight deep neural network (DNN) model archives a high accuracy of 98.2% and also removes noise more effectively. Conclusions: Our proposed approach has a lot of potential to help medical image analysis to help improve the accuracy of test results, and it may also prove helpful in saving patients’ lives.

A real-world retrospective study to assess efficacy and safety of alectinib as adjuvant therapy in IB-IIIB NSCLC patients harboring ALK rearrangement

BackgroundAlectinib has demonstrated promising disease-free survival (DFS) benefit for early-stage non-small cell lung cancer (NSCLC) patients with ALK rearrangement positive in phase 3 ALINA trial. However, real-world evidence for the efficacy and safety of alectinib in early-stage ALK-positive NSCLC is limited.Materials and methodsWe retrospectively reviewed 68 patients with stage IB-IIIB ALK-positive NSCLC who underwent complete pulmonary resections from April 2010 to July 2023 at a single institution. 38 (55.9%) enrolled patients had N2 lymph node metastasis, and 17 (24.9%) patients had multi-station N2 metastasis. Patients were stratified into two groups according to the adjuvant treatment regimen, with 19 patients in the alectinib group and 49 patients in the chemotherapy group. There were no significant differences in clinicopathological characteristics between the two groups. After curative resection surgery, patients in alectinib group received oral alectinib at a dose of 600 mg twice daily and patients in chemotherapy group received platinum-based doublet chemotherapy regimen every 3 weeks for 4 cycles. The primary endpoint was 3-year DFS. The Kaplan-Meier method was used to estimate DFS and overall survival (OS). Safety analyses were conducted by comparing the incidence of adverse events between the two groups.ResultsAt the last follow-up date (January 22th, 2024), A total of 1 (5.3%) and 28 (57.1%) DFS events were observed in alectinib group and chemotherapy group respectively. The 3-year DFS showed significant improvement in the alectinib group compared with chemotherapy group (91.7% vs 60.7%, P=0.051). In the IIIAN2 subgroup, the 3-year DFS rate in the alectinib group reached a satisfactory 87.5%. In both groups, the majority of AEs were graded as level 1 or 2, No grade 3-4 AEs were observed in alectinib group.ConclusionAlectinib, as adjuvant therapy, demonstrated favorable efficacy and manageable safety in patients with completely resected ALK-positive stage I B-IIIB non-small cell lung cancer. A limitation of this study is the small sample size, and a larger-scale real-world sample study is needed to further evaluate the efficacy and safety of alectinib as adjuvant therapy.

Development and validation of nomogram for predicting the cancer-specific survival among patients aged 80 and above with early-stage non-small cell lung cancer.

The use of nomograms in predicting the prognosis of early-stage non-small cell lung cancer (NSCLC), particularly in elderly patients, is not widespread. A validated prognostic model specifically for NSCLC patients over 80 years old holds promising potential for clinical application in forecasting patient outcomes. The prognostic value of various factors for NSCLC patients aged 80 and above was evaluated using data from the Surveillance, Epidemiology, and End Results (SEER) database (2010-2017). Kaplan-Meier (KM) curves, Cox proportional hazards regression models, and nomogram were utilized to evaluate the impact of each factor on cancer-specific survival (CSS). A cohort comprising 7045 individuals was selected for inclusion in the analysis. Through rigorous statistical analysis, 10 independent prognostic factors were identified and incorporated into the nomogram. The nomogram's receiver operating characteristic (ROC) curve area under the curve (AUC) was higher than that of the AJCC 7th edition TNM staging system's predicted CSS (0.744 versus 0.602), establishing the superior prognostic value of the nomogram. We have successfully created a highly accurate and discriminative nomogram that enables oncologists to predict the survival outcome of each individual patient with I/II NSCLC who is 80 years or older.

PD-L1+ Lymphocytes Are Associated with CD4+, Foxp3+CD4+, IL17+CD4+ T Cells and Subtypes of Macrophages in Resected Early-Stage Non-Small Cell Lung Cancer.

The non-canonical PD-L1 pathway revealed that programmed-death ligand 1 (PD-L1) expression in immune cells also plays a crucial role in immune response. Moreover, immune cell distribution in a tumour microenvironment (TME) is pivotal for tumour genesis. However, the results remain controversial and further research is needed. Distribution of PD-L1-positive (PD-L1+) tumour-infiltrating lymphocytes in the context of TME was assessed in 72 archival I-III stage surgically resected NSCLC tumour specimens. Predominant PD-L1+ lymphocyte distribution in the tumour stroma, compared to islets, was found (p = 0.01). Higher PD-L1+ lymphocyte infiltration was detected in smokers due to their predominance in the stroma. High PD-L1+ lymphocyte infiltration in tumour stroma was more common in tumours with higher CD4+ T cell infiltration in islets and stroma, Foxp3+CD4+ T cell infiltration in islets and lover M1 macrophage infiltration in the stroma (p = 0.034, p = 0.034, p = 0.005 and p = 0.034 respectively). Meanwhile, high PD-L1+ lymphocyte infiltration in islets was predominantly found in tumours with high levels of IL-17A+CD4+ T cells in islets and Foxp3+CD4+ T cells in islets and stroma (p = 0.032, p = 0.009 and p = 0.034, respectively). Significant correlations between PD-L1+ lymphocytes and tumour-infiltrating CD4+, Foxp3+CD4+, IL-17A+CD4+ T cells and M2 macrophages were found. An analysis of the tumour-immune phenotype revealed a significant association between PD-L1 expression and IL17+CD4+ and Foxp3+CD4+ immune phenotypes. PD-L1+ lymphocytes are associated with the distribution of CD4+, Foxp3+CD4+, IL17A+CD4+ T cells, M1 and M2 macrophages in TME of resected NSCLC.

Amplifying mutational profiling of extracellular vesicle mRNA with SCOPE.

Sequencing of messenger RNA (mRNA) found in extracellular vesicles (EVs) in liquid biopsies can provide clinical information such as somatic mutations, resistance profiles and tumor recurrence. Despite this, EV mRNA remains underused due to its low abundance in liquid biopsies, and large sample volumes or specialized techniques for analysis are required. Here we introduce Self-amplified and CRISPR-aided Operation to Profile EVs (SCOPE), a platform for EV mRNA detection. SCOPE leverages CRISPR-mediated recognition of target RNA using Cas13 to initiate replication and signal amplification, achieving a sub-attomolar detection limit while maintaining single-nucleotide resolution. As a proof of concept, we designed probes for key mutations in KRAS, BRAF, EGFR and IDH1 genes, optimized protocols for single-pot assays and implemented an automated device for multi-sample detection. We validated SCOPE's ability to detect early-stage lung cancer in animal models, monitored tumor mutational burden in patients with colorectal cancer and stratified patients with glioblastoma. SCOPE can expedite readouts, augmenting the clinical use of EVs in precision oncology.

Novel vaccines against lung cancer.

Despite recent advances in immunotherapy treatment for metastatic, early-stage nonsmall cell lung cancer (NSCLC), palliative, adjuvant, neoadjuvant, and perioperative treatment options, further development is needed. Exploring new frontiers of immuno-oncology is necessary. Researchers are interested in a therapeutic vaccination model. In this paper, we provide a review of the latest lung cancer therapeutic vaccines.We describe strategies for antigen selection and delivery platforms. As of 5th of August 2024, we have reviewed ongoing clinical trials and results.We summarize most of the important clinical trials of novel vaccines, the way of action, and available clinical data. We also discuss the pros and cons of various types of therapeutic vaccines. Until recently, clinical trial results were mixed regarding the efficacy of therapeutic vaccines in lung cancer.Developing next-generation sequencing and bioinformatic technologies has helped identify suitable antigens. New personalized vaccines are based on neoantigens specific to unique tumor mutations.Neoantigens, instead of tumor-associated antigens, better delivery systems and adjuvants will improve antigen presentation and immune system activation.Combining these therapeutic vaccines with other therapeutic approaches will improve and prolong the response.

Racial/ethnic disparities in curative-intent treatment for early-stage non-small cell lung cancer patients among heterogeneous Black populations: US-born Black, Afro-Haitian, West Indian Black, and Hispanic Black.

Heterogeneous Black populations encounter significant obstacles in accessing cancer care, yet research on lung cancer treatment disparities remains limited. This study investigates whether the disparity in receiving curative-intent treatment (curative-intent surgery and/or stereotactic body radiation therapy [SBRT]) for early-stage non-small cell lung cancer (NSCLC) between non-Hispanic Whites (NHWs) and total Blacks extends to diverse Black populations, including US-born, Afro-Haitian, West Indian Black, and Hispanic Black individuals. This cross-sectional study included all Florida cancer registry early-stage NSCLC cases 2005-2017, linked to individual-level discharge data containing comorbidity and specific treatment details (surgery and/or SBRT). Multivariable logistic regression assessed the association between race/ethnicity and the receipt of curative-intent treatment, while accounting for sociodemographic factors (poverty, age, insurance, and smoking status) and clinical variables. Among 55,655 early-stage NSCLC patients, 71.1% received curative-intent treatment: 72.1% NHW and 59.7% Black (non-Hispanic and Hispanic)individuals. Black patients had 35% lower odds (ORadj, 0.65; 95% CI, 0.59-0.70) of receiving curative-intent treatment compared to NHW patients. ORs varied from 0.57 (95% CI, 0.59-0.70) for Hispanic Black to 0.76 (95% CI, 0.56-1.02) for West Indian Black. Remarkably, Black-White disparities persisted despite the availability of curative treatment options (SBRT) for both high Charlson Comorbidity Index (CCI) observed among US-born Blacks and surgery for low CCI patients among all other Black subgroups. Pronounced disparities in accessing curative-intent treatments for early-stage NSCLC were evident across all Black subgroups, regardless of treatment availability and comorbidity profile. These findings underscore the need to address Black heterogeneity and prompt further research to rectify treatment disparities in early-stage NSCLC.

Measuring the Integration of Stereotactic Ablative Radiotherapy Plus Surgery for Early-Stage Non-Small Cell Lung Cancer (MISSILE): Long-Term Clinical Outcomes.

For early-stage non-small cell lung cancer (NSCLC), surgery is the preferred approach in operable patients, whereas stereotactic ablative radiotherapy (SABR) is preferred for medically inoperable patients. The combination of neoadjuvant SABR followed by surgery was tested in the MISSILE phase II trial. We report long-term outcomes, beyond 5 years of follow-up. Patients diagnosed with T1-2N0M0 NSCLC with good performance status and adequate lung function were enrolled. Patients underwent neoadjuvant SABR followed by lobectomy/wedge resection. Forty enrolled patients received SABR, of which 36 patients proceeded to surgery. The pathologic and major complete response rates were 60% and 63%, respectively. Median follow-up was 6.6 years following surgery. Five-year overall, disease-free and cancer-specific survival were 66.7% (95% CI: 48.8-79.5), 58.3% (95% CI: 40.7-72.4) and 76.4% (95% CI: 58.2-87.4). Five-year local, regional and distant control were 93.5% (95% CI: 76.3-98.4), 80.1% (95% CI: 62.7-90.0) and 82.4% (95% CI: 64.9-91.7). After SABR and surgery, 16.7% (n=6) of patients experienced related grade ≥ 3 adverse events and there were no grade 5 events. The combined approach of SABR and surgery was safe and demonstrated reasonable long-term clinical outcomes, but similar to surgery alone.

The relationship between sarcopenia and metabolic parameters of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) and the prognostic value of sarcopenia in early-stage non-small cell lung cancer.

Patients with lung cancer face a heightened risk of developing sarcopenia. Despite this known risk, the impact of sarcopenia on the long-term prognosis of lung cancer patients, specifically concerning progression-free survival (PFS) and overall survival (OS), remains unclear. The primary objective of our study was to examine the correlation between metabolic parameters derived from 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) and sarcopenia, as well as the prognostic value of sarcopenia in patients with surgically resected early-stage non-small cell lung cancer (NSCLC). In this retrospective cross-sectional study, we analyzed 187 NSCLC patients who underwent 18F-FDG PET/CT at the First Affiliated Hospital of Soochow University between March 2019 and October 2023. Patients were divided into two groups based on the presence (n=46) or absence (n=141) of sarcopenia. The correlation between sarcopenia, metabolic parameters, and patient characteristics was evaluated using chi-square and Mann-Whitney U tests. Survival analyses, including PFS and OS, were conducted using Kaplan-Meier analysis and Cox proportional hazards regression. Based on sarcopenia, metabolic parameters and patient characteristics, patients were classified into high-risk (n=28), intermediate-risk (n=121), and low-risk (n=38) groups. Our analysis identified gender, body mass index (BMI), psoas Hounsfield unit (HU), and maximum standardized uptake value of the psoas major muscle (SUVmax-Muscle) as independent predictors of sarcopenia (P<0.05 for all). A nomogram model, utilizing these parameters, was constructed to predict sarcopenia. Survival analysis further demonstrated that total lesion glycolysis [hazard ratio (HR) =2.499; 95% confidence interval (CI): 2.014-3.267; P=0.016], sarcopenia (HR =3.323; 95% CI: 1.748-6.316; P<0.001), and programmed death ligand-1 (PD-L1) expression (HR =0.093; 95% CI: 0.012-0.698; P=0.021) emerged as independent predictors of OS in early-stage NSCLC. Notably, patients categorized as high-risk, characterized by elevated total lesion glycolysis, presence of sarcopenia, and PD-L1 positivity, exhibited a significantly poorer prognosis compared to the intermediate-risk (P<0.05) and low-risk groups (P<0.05). Our findings indicated an inverse relationship between SUVmax-Muscle or psoas HU with the incidence of sarcopenia in NSCLC patients. Additionally, total lesion glycolysis, sarcopenia, and PD-L1 expression were identified as independent prognostic factors for OS in early-stage NSCLC. The risk stratification model, incorporating total lesion glycolysis, sarcopenia, and PD-L1 expression, assumed a pivotal role in guiding personalized therapy decisions and post-treatment monitoring.

Real-world Decision-making Process for Stereotactic Body Radiotherapy Versus Minimally Invasive Surgery in Early-stage Lung Cancer Patients.

To generate a prediction model for selection of treatment modality for early-stage non-small cell lung cancer (NSCLC). Stereotactic body radiotherapy (SBRT) and minimally invasive surgery (MIS) are used in the local treatment of early-stage NSCLC. However, selection of patients for either SBRT or MIS remains challenging, due to the multitude of factors influencing the decision-making process. We analyzed 1291 patients with clinical stage I NSCLC treated with intended MIS or SBRT from January 2020 to July 2023. A prediction model for selection for SBRT was created based on multivariable logistic regression analysis. The receiver operating characteristic curve analysis stratified the cohort into 3 treatment-related risk categories. Post-procedural outcomes, recurrence and overall survival (OS) were investigated to assess the performance of the model. In total, 1116 patients underwent MIS and 175 SBRT. The prediction model included age, performance status, previous pulmonary resection, MSK-Frailty score, FEV1 and DLCO, and demonstrated an area-under-the-curve of 0.908 (95%CI, 0.876-0.938). Based on the probability scores (n=1197), patients were stratified into a low-risk (MIS, n=970 and SBRT, n=28), intermediate-risk (MIS, n=96 and SBRT, n=53) and high-risk category (MIS, n=10 and SBRT, n=40). Treatment modality was not associated with OS (HR of SBRT, 1.67 [95%CI: 0.80-3.48]; P=0.20). Clinical expertise can be translated into a robust predictive model, guiding the selection of stage I NSCLC patients for MIS versus SBRT and effectively categorizing them into three distinct risk groups. Patients in the intermediate category could benefit most from multidisciplinary evaluation.
