BMC Cancer 2024; 24:883. [PMID: 39039505 PMCID: PMC11265358 DOI: 10.1186/s12885-024-12523-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2024] [Accepted: 06/14/2024] [Indexed: 07/24/2024] Open
Abstract
BACKGROUND The role of miR-145-5p in non-small cell lung cancer (NSCLC) has been studied, however, the regulation of hBMSCs-derived exosomes (Exo) transmitted miR-145-5p in NSCLC was still unknown. This study aimed to investigate the role of hBMSCs-derived exosomes (Exo) in the progression of NSCLC. METHODS The Exo was extracted from hBMSCs and added to A549 and H1299 cell culture, followed by the detection of cell proliferation, migration, and invasion. The correlation between the expression of miR-145-5p and SOX9, as well as their binding relationship was determined by correlation analysis, luciferase gene reporter assay and RNA pull-down assays. The in vivo animal model was established to further verify the impact of hBMSCs-Exo. RESULTS It showed that miR-145-5p was downregulated and SOX9 was upregulated in NSCLC tissues. HBMSCs-derived Exo, and hBMSCs-Exo with overexpression of miR-145-5p could inhibit cell proliferation, migration, and invasion of both A549 and H1299 cells, and prevent against tumor progression in vivo. MiR-145-5p and SOX9 were found to be able to bind to each other, and a negative correlation were observed between the expression of them in NSCLC tissues. Furthermore, inhibition of SOX9 could reversed the suppressed role of miR-145-5p in vitro and in vivo. CONCLUSION Therefore, HBMSCs-Exo effectively transmitted miR-145-5p, leading to the suppression of malignant development in NSCLC through the regulation of SOX9.

Arch Med Sci 2024; 20:887-908. [PMID: 39050162 PMCID: PMC11264083 DOI: 10.5114/aoms/174578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Accepted: 10/27/2023] [Indexed: 07/27/2024] Open
Abstract
Introduction The study was designed to explore how cinobufagin (CB) regulates the development of non-small cell lung cancer (NSCLC) cells through lipid rafts. Material and methods The effects of CB at gradient concentrations (0, 0.5, 1 and 2 µM) on NSCLC cell viability, apoptosis, reactive oxygen species (ROS) level, phosphorylation of Akt, and apoptosis- and lipid raft-related protein expression were assessed by MTT assay, flow cytometry and Western blot. Cholesterol and sphingomyelin were labeled with BODIPY to evaluate the effect of CB (2 µM) on them. Sucrose density gradient centrifugation was used to extract lipid rafts. The effect of CB on the expression and distribution of caveolin-1 was determined by immunofluorescence, quantitative reverse transcription polymerase chain reaction and Western blot. After overexpression of caveolin-1, the above experiments were performed again to observe whether the regulatory effect of CB was reversed. Results CB inhibited NSCLC cell viability while promoting apoptosis and ROS level. CB redistributed the lipid content on the membrane surface and reduced the content of caveolin-1 in the cell membrane. In addition, CB repressed the activation of AKT. However, caveolin-1 overexpression reversed the effects of CB on apoptosis, AKT activation and lipid raft. Conclusions CB regulates the activity of Akt in lipid rafts by inhibiting caveolin-1 expression to promote NSCLC cell apoptosis.

Optimizing perioperative treatment for potentially resectable stage III squamous cell lung carcinoma: promising results of a condensed four-cycle regimen with tislelizumaband chemotherapy. BMC Med 2024; 22:234. [PMID: 38853265 PMCID: PMC11163755 DOI: 10.1186/s12916-024-03462-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Accepted: 05/30/2024] [Indexed: 06/11/2024] Open
Abstract
BACKGROUND The standard care for resectable non-small cell lung cancer (NSCLC) involves perioperative therapy combining chemotherapy and immune checkpoint inhibitors, typically lasting 6 to 12 months. However, the optimal treatment strategies for potentially resectable squamous cell lung carcinoma (SCC) remain unclear. This Phase 2 trial aimed to assess the efficacy and safety of a condensed four-cycle perioperative treatment regimen with tislelizumab combined with chemotherapy in patients with potentially resectable stage III SCC. METHODS Patients with potentially resectable stage IIIA-IIIB (N2) SCC received intravenous tislelizumab, albumin-bound paclitaxel, and carboplatin for up to four cycles. The primary endpoints were major pathologic response (MPR) and incidence of treatment-related adverse events. Safety and potential biomarkers for efficacy prediction were also assessed. RESULTS Among 35 enrolled patients, 32 underwent surgery with R0 resection achieved in all cases. MPR was achieved in 24 patients and pathological complete response (pCR) in 14 patients. Radiographic objective response was observed in 31 patients. The 12-month and 24-month event-free survival rate was 85.7 and 61.0%, respectively. Four patients experienced grade 3 or 4 adverse events. Tumor tissue based next-generation sequencing revealed the potential associations between several biomarkers and pathological response, including tumor neoantigen burden score, 18-gene expression profile score, CD8 + T cells, M1/M2 macrophages ratio and interferon-gamma expression level. Besides, circulating tumor DNA (ctDNA) dynamics and concentration were also associated with pathological response and the presence of ctDNA at postoperative month 1 was a strong predictor for disease relapse. Furthermore, metagenomic sequencing in bronchoalveolar lavage fluid demonstrated Streptococcus was the most abundant genus in the pCR group. CONCLUSIONS A condensed four-cycle perioperative treatment regimen of tislelizumab combined with chemotherapy demonstrated promising efficacy and manageable toxicities in potentially resectable stage III SCC. Specific biomarkers showed potential for predicting treatment efficacy and the mechanism of superior antitumor response of pCR patients was preliminarily and indirectly explored.

Induction chemoimmunotherapy with surgery versus concurrent chemoradiation followed by immunotherapy for stage III-N2 non-small cell lung cancer. J Thorac Cardiovasc Surg 2024; 167:1895-1905.e2. [PMID: 37722622 DOI: 10.1016/j.jtcvs.2023.09.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Revised: 08/15/2023] [Accepted: 09/11/2023] [Indexed: 09/20/2023]
Abstract
OBJECTIVE Despite the growing relevance of immunotherapy for non-small cell lung cancer (NSCLC), there is limited consensus on the optimal treatment strategy for locally advanced NSCLC. This study evaluated the overall survival of patients with stage III-N2 NSCLC undergoing induction chemoimmunotherapy with surgery (CT/IO+Surgery) and definitive concurrent chemoradiation followed by immunotherapy (cCRT+IO). METHODS Patients with cT1-3, N2, M0 NSCLC in the National Cancer Database (2013 to 2019) were included and stratified by treatment regimen: CT/IO+Surgery or cCRT+IO. Overall survival was evaluated using Kaplan-Meier analysis, Cox proportional hazards modeling, and propensity score matching on 10 prognostic variables. RESULTS Of the 3382 patients who met the study eligibility criteria, 3289 (97.3%) received cCRT+IO and 93 (2.8%) received CT/IO+Surgery. The 3-year overall survival of the entire cohort was 58.2% (95% CI, 56.2% to 60.1%). Multivariable-adjusted Cox proportional hazards modeling demonstrated better survival after CT/IO+Surgery than after cCRT+IO (hazard ratio [HR], 0.52; 95% confidence interval [CI], 0.32 to 0.84; P = .007). In a 3:1 variable ratio propensity score-matched analysis of 223 patients who received cCRT+IO and 76 patients who received CT/IO+Surgery, 3-year overall survival was 63.2% (95% CI, 55.9% to 70.2%) after cCRT+IO and 77.2% (95% CI, 64.6% to 85.7%) after CT/IO+Surgery (P = .029). CONCLUSIONS In this national analysis, multimodal treatment including immunotherapy was associated with a 3-year overall survival rate of 58.2% for all patients with stage III-N2 NSCLC and 77.2% for patients who underwent chemoimmunotherapy followed by surgery. These results should be considered hypothesis-generating and demonstrate the importance of developing a randomized trial to evaluate the role of surgery versus chemoradiation for locally advanced NSCLC in the modern immunotherapy era.

Abstract
BACKGROUND The safety and efficacy of video-assisted thoracic surgical (VATS) versus open lobectomy for non-small-cell lung cancer (NSCLC) following neoadjuvant therapy remained controversial. The aim of this study was to compare the outcomes of VATS with those of open lobectomy for NSCLC after neoadjuvant therapy. METHODS Patients who had undergone VATS or open lobectomy for NSCLC following neoadjuvant therapy in nine hospitals in China from July 2014 to July 2020 were retrospectively reviewed. The clinical characteristics and overall survival (OS) of patients were analyzed using Cox regression models and propensity score matching. RESULTS We identified 685 patients, 436 (63.6%) who had undergone VATS lobectomy and 249 (36.4%) who had undergone open lobectomy. Patients who had undergone VATS lobectomy tended to have had fewer nodes removed than those who had undergone open lobectomy. However, compared with open group, the VATS group had a better perioperative outcome, such as smaller blood loss volumes and shorter postoperative stays. The groups had a similar operation durations and postoperative complications, and there was a nonsignificant difference between their 30-day mortality rates. After propensity score matching, there was no significant different between the OS of the groups, and only postoperative adjuvant therapy was associated with worse OS. CONCLUSION This multi-center analysis of patients with NSCLC who had undergone surgery subsequent to neoadjuvant therapy reveals that VATS lobectomy tended to have a better perioperative outcome, and have a similar OS compared to open lobectomy. These findings suggest that VATS lobectomy is appropriate for NSCLC following neoadjuvant therapy.

Cell Signal 2024; 117:111095. [PMID: 38346527 DOI: 10.1016/j.cellsig.2024.111095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 01/26/2024] [Accepted: 02/09/2024] [Indexed: 02/16/2024]
Abstract
MicroRNA-7 (miRNA-7, miR-7) is a unique class of tumor suppressors, plays an important role in various physiological and pathological processes including human non-small cell lung cancer (NSCLC). In previous works, we revealed that miR-7 could regulate the growth and metastasis of human NSCLC cells. However, the mechanism of dysregulated miR-7 expression in NSCLC remains to be further elucidated. In this study, based on clinical sample analysis, we found that the downregulated expression of miR-7 was dominantly attributed to the decreased level of pri-miR-7-2 in human NSCLC. Furthermore, there were four site mutations in the miR-7-2 promoter sequence. Notably, among these four sites, mutation at -1312 locus (A → C, termed as A1312C mutation) was dominate, and A1312C mutation further led to decreased expression of miR-7 in human NSCLC cells, accompanied with elevated transduction of NDUFA4/ERK/AKT signaling pathway. Mechanistically, homeobox A5 (HOXA5) is the key transcription factors regulating miR-7 expression in NSCLC. A1312C mutation impairs HOXA5 binding, thereby reducing the transcriptional activity of miR-7-2 promoter, resulting in downregulation of miR-7 expression. Together, these data may provide new insights into the dysregulation of specific miRNA expression in NSCLC and ultimately prove to be helpful in the diagnostic, prognostic, and therapeutic strategies against NSCLC.

PLoS One 2024; 19:e0294227. [PMID: 38564630 PMCID: PMC10986975 DOI: 10.1371/journal.pone.0294227] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Accepted: 10/20/2023] [Indexed: 04/04/2024] Open
Abstract
Current evidence suggests that DEP domain containing 1 (DEPDC1) has an important effect on non-small-cell lung cancer (NSCLC). However, the diagnostic value and the regulatory function within NSCLC are largely unclear. This work utilized publicly available databases and in vitro experiments for exploring, DEPDC1 expression, clinical features, diagnostic significance and latent molecular mechanism within NSCLC. According to our results, DEPDC1 was remarkably upregulated in the tissues of NSCLC patients compared with non-carcinoma tissues, linked with gender, stage, T classification and N classification based on TCGA data and associated with smoking status and stage according to GEO datasets. Meanwhile, the summary receiver operating characteristic (sROC) curve analysis result showed that DEPDC1 had a high diagnostic value in NSCLC (AUC = 0.96, 95% CI: 0.94-0.98; diagnostic odds ratio = 99.08, 95%CI: 31.91-307.65; sensitivity = 0.89, 95%CI: 0.81-0.94; specificity = 0.92, 95%CI: 0.86-0.96; positive predictive value = 0.94, 95%CI: 0.89-0.98; negative predictive value = 0.78, 95%CI: 0.67-0.90; positive likelihood ratio = 11.77, 95%CI: 6.11-22.68; and negative likelihood ratio = 0.12, 95%CI: 0.06-0.22). Subsequently, quantitative real-time PCR (qRT-PCR) and western blotting indicated that DEPDC1 was high expressed in NSCLC cells. According to the in vitro MTS and apoptotic assays, downregulated DEPDC1 expression targeting P53 signaling pathway inhibited the proliferation of NSCLC cells while promoting apoptosis of NSCLC cells. Moreover, DEPDC1 was significantly correlated with immune cell infiltrating levels in NSCLC based on TCGA data, which were primarily associated with T cells CD4 memory activated, macrophages M1, B cells memory, mast cells resting, T cells regulatory, monocytes, and T cells CD4 memory resting. Compared with the group with high expression of DEPDC1, the group with low expression level had higher scores for immune checkpoint inhibitors (ICIs) treatment. GSEA confirmed that DEPDC1 was involved in gene expression and tumor-related signaling pathways. Finally, DEPDC1 and its associated immune-related genes were shown to be enriched in 'receptor ligand activity', 'external side of plasma membrane', 'regulation of innate immune response', and 'Epstein-Barr virus infection' pathways. The present study demonstrates that DEPDC1 may contribute to NSCLC tumorigenesis and can be applied as the biomarker for diagnosis and immunology.

Abstract
BACKGROUND Stage III non-small cell lung cancer is a heterogeneous disease. Several international guidelines recommend neoadjuvant treatment before surgery; however, upfront surgery is the preferred approach for technically resectable non-small cell lung cancer in East Asia. The aim of this retrospective study was to evaluate the long-term outcomes of curative-intent upfront surgery in stage IIIA/B non-small cell lung cancer. METHODS Patients who underwent curative-intent upfront surgery with stage cIIIA/B non-small cell lung cancer were identified. The clinical and pathological variables and survival outcomes were evaluated. RESULTS Overall, 664 patients were identified, of whom 320 (48.8%) had N2 disease, 66.7% were males, 49.4% had a smoking history, and 61.2% had lung adenocarcinoma. Lobectomy was the most performed surgical procedure (84.9%). A total of 40 patients (6.02%) had positive margins (R1/R2). The grade III adverse event rate was 2.0% (13 of 664). The median follow-up was 30.6 (range 1.9-97.7) months. At follow-up, the mortality rate was 13.3% (88 of 664) and 37.2% of patients (247 of 664) had recurrence. Lung (101 of 247 (40.9%)) and brain (53 of 247 (21.5%)) were the most common sites of recurrence. The median overall survival was 60.0 (95% c.i. 51.5 to 67.6) months, with overall survival probability at 1, 2, 3, and 5 years being 89.6%, 77.8%, 67.2%, and 49.0% respectively. The R0 cohort showed an improved median overall survival compared with the R1/R2 cohort (67.4 versus 26.5 months respectively; P = greater than 0.001). The multivariable analysis revealed that age greater than or equal to 65 years (HR 1.51, 95% c.i. 1.08 to 2.12; reference = age less than 65 years), tumour size (greater than or equal to 5 cm (HR 2.13, 95% c.i. 1.41 to 3.21) and greater than or equal to 3 cm but less than 5 cm (HR 1.15, 95% c.i. 0.78 to 1.71); reference = less than 3 cm), and adjuvant treatment (chemotherapy (HR 0.69, 95% c.i. 0.49 to 0.96) and targeted therapy (HR 0.30, 95% c.i. 0.12 to 0.76); reference = none) significantly predicted overall survival. CONCLUSION Upfront surgery is an option for the management of stage IIIA/B non-small cell lung cancer.

[PMID: 38496376 PMCID: PMC10941003 DOI: 10.1016/j.jtocrr.2024.100654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 02/01/2024] [Accepted: 02/17/2024] [Indexed: 03/19/2024] Open
Abstract
Introduction Multiple clinical trials have revealed the benefit of immunotherapy (IO) for NSCLC, including unresectable stage III disease. Our aim was to investigate the impact of IO use on treatment and outcomes of potentially resectable stage IIIA NSCLC in a broader nationwide patient cohort. Methods We queried the National Cancer Database (2004-2019) for patients with stage IIIA (T1-2N2) NSCLC. Treatment and survival were evaluated with descriptive statistics, logistic regression, Kaplan-Meier analysis, and Cox proportional hazards modeling. Results Overall, 5.5% (3777 of 68,335) of patients received IO. IO use was uncommon until 2017, but by 2019, it was given to 40.1% (1544 of 2308) of stage IIIA patients. The increased use of IO after 2017 was associated with increased definitive chemoradiation treatment (54.2% [6800 of 12,535] from years 2017 to 2019 versus 46.9% [26,251 of 55,914] from 2004 to 2016, p < 0.001) and less use of surgery (18.1% [2266 of 12,535] from years 2017 to 2019 versus 22.0% [12,300 of 55,914] from 2004 to 2016, p < 0.001). IO treatment was associated with significantly better 5-year survival in the entire cohort (36.9% versus 23.4%, p < 0.001) and the subsets of patients treated with chemoradiation (37.2% versus 22.7%, p < 0.001) and surgery (48.6% versus 44.3%, p < 0.001). Pneumonectomy use decreased with increased IO treatment (5.1% of surgical patients [116 of 2266] from years 2017 to 2019 versus 9.2% [1127 of 12,300] from 2004 to 2016, p < 0.001). Conclusions Increased use of IO was associated with a change in treatment patterns and improved survival for patients with stage IIIA(N2) NSCLC.

Abstract
BACKGROUND The main challenge in personalized treatment of breast cancer (BC) is how to integrate massive amounts of computing resources and data. This study aimed to identify a novel molecular target that might be effective for BC prognosis and for targeted therapy by using network-based multidisciplinary approaches. METHODS Differentially expressed genes (DEGs) were first identified based on ESTIMATE analysis. A risk model in the TCGA-BRCA cohort was constructed using the risk score of six DEGs and validated in external and clinical in-house cohorts. Subsequently, independent prognostic factors in the internal and external cohorts were evaluated. Cell viability CCK-8 and wound healing assays were performed after PTGES3 siRNA was transiently transfected into the BC cell lines. Drug prediction and molecular docking between PTGES3 and drugs were further analyzed. Cell viability and PTGES3 expression in two BC cell lines after drug treatment were also investigated. RESULTS A novel six-gene signature (including APOOL, BNIP3, F2RL2, HINT3, PTGES3 and RTN3) was used to establish a prognostic risk stratification model. The risk score was an independent prognostic factor that was more accurate than clinicopathological risk factors alone in predicting overall survival (OS) in BC patients. A high risk score favored tumor stage/grade but not OS. PTGES3 had the highest hazard ratio among the six genes in the signature, and its mRNA and protein levels significantly increased in BC cell lines. PTGES3 knockdown significantly inhibited BC cell proliferation and migration. Three drugs (gedunin, genistein and diethylstilbestrol) were confirmed to target PTGES3, and genistein and diethylstilbestrol demonstrated stronger binding affinities than did gedunin. Genistein and diethylstilbestrol significantly inhibited BC cell proliferation and reduced the protein and mRNA levels of PTGES3. CONCLUSIONS PTGES3 was found to be a novel drug target in a robust six-gene prognostic signature that may serve as a potential therapeutic strategy for BC.

Abstract
The optimal positioning and usage of serum tumor markers (STMs) in advanced non-small cell lung cancer (NSCLC) care is still unclear. This review aimed to provide an overview of the potential use and value of STMs in routine advanced NSCLC care for the prediction of prognosis and treatment response. Radiological imaging and clinical symptoms have shown not to capture a patient's entire disease status in daily clinical practice. Since STM measurements allow for a rapid, minimally invasive, and safe evaluation of the patient's tumor status in real time, STMs can be used as companion decision-making support tools before start and during treatment. To overcome the limited sensitivity and specificity associated with the use of STMs, tests should only be applied in specific subgroups of patients and different test characteristics should be defined per clinical context in order to answer different clinical questions. The same approach can similarly be relevant when developing clinical applications for other (circulating) biomarkers. Future research should focus on the approaches described in this review to achieve STM test implementation in advanced NSCLC care.

Abstract
PURPOSE OF REVIEW The treatment of stage III N2 non-small cell lung cancer (NSCLC) remains debated. There is an absence of a universally agreed definition of resectability for this heterogeneous group and a lack of trial data. RECENT FINDINGS We reviewed and compared current international guidelines and evidence surrounding management of stage III N2 NSCLC. The Irish and Australian guidelines advise subcategorising N2 disease into N2a (may be resectable) and N2b (never resectable). On the contrary, American and British guidelines avoid subcategorising N2 disease, emphasising importance of local MDT decisions. It is suggested that evidence for resection of stage III tumours is relatively weak, but that stage IIIA should generally be considered for resection, and stage IIIB is not recommended for resection. For resectable disease, surgery may be combined with neoadjuvant chemoimmunotherapy, or adjuvant chemotherapy followed by immunotherapy and radiotherapy in selected patients. There is some evidence that technically resectable disease can be treated solely with radiotherapy with similar outcomes to resection. In the event of unresectable disease, chemoradiotherapy has been the traditional management option. However, recent studies with chemoradiotherapy alongside immunotherapy appear promising. There are many factors that influence the treatment pathway offered to patients with stage III N2 NSCLC, including patient factors, team expertise, and local resources. Therefore, the role of MDTs in defining resectability and formulating an individualised treatment plan is crucial.

Abstract
BACKGROUND In stage IIIA non-small cell lung cancer (NSCLC), surgery plays a role in terms of multimodal treatment. Surgery rates have increased in recent years, mainly due to the combination of more accurate imaging tools, electromagnetic navigation bronchoscopy, robotic bronchoscopy, robotic surgery, and a wide range of challenging clinical scenarios to lead surgeons and oncologists to include surgery as an option in therapeutic management. OBJECTIVES To assess the prognostic factors, the 5-year overall survival (OS) and cancer-specific survival (CSS) of patients with resectable stage III-NSCLC. METHODS Patients' information was extracted from 76 Hospitals' Cancer Registry. OS and CSS were constructed using the Kaplan-Meier method, and the log-rank test was used to assess differences between curves. In addition, Cox regression was conducted to evaluate the patients' characteristics leading to better OS and CSS. RESULTS Overall, 433 stage III NSCLC surgical patients followed over 19 years were included. The median age was 61.29 ± 9.62 years, 58.4% male, 50.1% with adenocarcinoma, 29.3% with squamous cell carcinoma, 3.7% with large-cell lung carcinoma, and 16,9% with other lung cancer types. The 5-year OS was 30.6% (95% confidence interval [CI]: 27.4-36.1), and the CSS was 35.0% (95% CI: 29.4-41.0). In the Cox multivariate regression, squamous cell carcinoma was associated with reduced OS (hazard ratio [HR]: 1.40; 95% CI: 1.07-1.83; p=0.014) and CSS (HR: 1.56; 95% CI: 1.17-2.08; p = 0.002), in comparison with adenocarcinoma. The 2015-2019 quinquennial had a 50% reduction in HR (0.49; 95% CI: 0.29-0.81; p = 0.006), and the 2010-2014 group had a 40% reduction (0.59; 95% CI: 0.42-0.83; p = 0.006) in comparison with the 2000-2004 patients' group. CONCLUSION The OS and CSS of patients with resectable stage III NSCLC have improved over the past 19 years in our region. Squamous cell carcinoma was associated with increased mortality risk from any cause or specific cancer.

Abstract
As stage IIIC non-small cell lung cancer (NSCLC) is not recommended for surgical resection, the survival and prognosis for stage IIIC NSCLC remain poor. More powerful and individualized therapies are urgently needed to improve the prognosis of stage IIIC NSCLC. Recently, immunotherapeutics have been increasingly considered in the neoadjuvant therapy of NSCLC. This study presents a patient with stage IIIC NSCLC achieving a pathological complete response (pCR) following conversion therapy with immunotherapy plus chemotherapy. This case also presents a histologic transformation from squamous cell carcinoma to adenocarcinoma after prolonged progression-free survival (PFS) following surgery. Collectively, this case suggests that conversion immunotherapy with chemotherapy and subsequent surgery can be considered and benefits a subset of unresectable stage IIIC NSCLC.

Abstract
BACKGROUND Adenocarcinoma (AC) and squamous cell carcinoma (SCC) are the most frequent histological subtypes of non-small cell lung cancer (NSCLC). The aim of this study was to investigate how patients with AC and SCC benefit from image-guided adaptive radiotherapy (ART) with tumour match. MATERIAL AND METHODS Consecutive patients diagnosed with AC or SCC of the lung treated with definitive chemo-radiotherapy before and after the implementation of ART and tumour match were retrospectively included for analyses. Data collection included baseline patient and treatment characteristics in addition to clinical data on radiation pneumonitis (RP), failure, and survival. Patients were divided into four categories based on their histology and treatment before (n = 173 [89 AC and 84 SCC]) and after implementation of ART (n = 240 [141 AC and 99 SCC]). RESULTS Median follow-up was 5.7 years for AC and 6.3 years for SCC. Mean lung dose decreased for both histologies with ART, whereas mean heart dose only decreased for patients with AC. Incidences of grade 3 and 5 RP decreased for both histologies with ART. Loco-regional failure (LRF) rates decreased significantly for patients with SCC after ART (p = .04), no significant difference was observed for AC. Overall survival (OS) increased significantly for SCC after ART (p < .01): the 2-year OS increased from 31.0% (95% confidence interval [CI] [22.5-42.6]) to 54.5% (95% CI [45.6-65.3]). No significant effect on OS was observed for patients with AC. CONCLUSION ART and tumour match in the radiotherapeutic treatment of patients with locally advanced NSCLC primarily led to decreased LRF and improved OS for patients with SCC.

Abstract
Background In the past, multiple studies have offered incremental evidence that indicates that competitive endogenous RNA (ceRNA) regulatory networks are involved in tumor growth and present novel therapeutic targets. Herein, we investigated the impact of thymidine kinase 1 (TK1)-related ceRNA networks on the prognosis of non-small cell lung cancer (NSCLC). Methods TK1 expression data in NSCLC and normal tissue samples were retrieved from the Cancer Genome Atlas (TCGA) database and were then compared. Thereafter, the findings of the immunohistochemical staining experiments and clinical follow-up data derived from patients with NSCLC were used for conducting prognostic analysis. The starBase database was searched to determine TK1-targeted microRNAs and long non-coding RNAs, and clinical data from TCGA were used for survival analysis to construct a ceRNA network associated with TK1 expression and prognosis. Finally, the roles played by methylation and immunity in the prognosis and treatment of NSCLC were analyzed. Results Our findings revealed that the cancer tissues expressed significantly higher TK1 levels than normal tissues, and the follow-up clinical data revealed that the prognosis was generally worse in the high-expression patients than in the low-expression patients. In addition, clinical data collected from the starBase and TCGA databases showed that the LINC00665/has-let-7b-5p/TK1 network could influence the growth and prognosis of NSCLC. It was also noted that the TK1 methylation site was correlated with the prognosis of NSCLC, and immunoprognostic analysis further indicated that patients with higher TK1 expression levels displayed a worse prognosis. Conclusion When the regulatory network of LINC00665/has-let-7b-5p/TK1 was assessed, it was observed that elevated TK1 levels may affect the prognosis of NSCLC. Therefore, it could be considered a prognostic biomarker and a probable therapeutic target for predicting NSCLC prognosis.

Abstract
PURPOSE Lung cancer remains the leading cause of cancer-related mortality worldwide, mostly due to delayed diagnosis. The objective of this study is to examine the treatment patterns and overall survival (OS) outcomes in a cohort of patients diagnosed with stage III non-small cell lung cancer (NSCLC) over a period of 12 years in Germany. METHODS This retrospective study is based on German cancer registry data and included 14,606 stage III NSCLC patients diagnosed during 2007-2018. Three time-periods were defined according to the availability of advanced diagnostic and treatment strategies (2007-2010 low availability era (LAE), 2011-2014 transition era (TE), 2015-2018 modern era (ME)). Patients were categorized according to the treatment they received during those eras. Kaplan-Meier curves and multivariate Cox proportional hazards models were used to investigate the association between being diagnosed during a certain era and survival. The hazard ratio (HR) estimates were reported along with the 95% confidence interval (CI). RESULTS The median OS rose from 16 months in the LAE to 22 months in the ME. The HR for patients diagnosed and treated in the ME was estimated to be [0.78; 95% CI (0.74-0.83)] compared to those diagnosed and treated in LAE. The benefit was most evident for patients treated by radiotherapy and chemotherapy [HR 0.73 95% CI (0.66-0.82)]. CONCLUSION This study highlights the importance of diagnostic and treatment advances in improving outcomes for lung cancer patients. Further studies are needed to assess progress in survival rates with current immunotherapy integration.

Abstract
Anchoring filament protein ladinin-1 (LAD1) codes for an anchor filament protein in the basement membrane. Here, we have aimed to determine its potential role in LUAD. According to the comprehensive analyses conducted in this study, we studied the expression, prognostic significance, function, methylation, copy number variations, and the immune cell infiltration of LAD1 in LUAD. A higher level of LAD1 gene expression was observed in the LUAD tumor tissues compared to the normal lung tissues (p < 0.001). Furthermore, the multivariate analysis indicated that a higher LAD1 gene expression level was the independent prognostic factor. Additionally, the DNA methylation level of the LAD1 was inversely linked to its expression (p < 0.001). We noted that the patients affected due to LAD1 hypomethylation showed a very low overall survival rate compared to the patients with a higher LAD1 methylation score (p < 0.05). Moreover, the results of the immunity analysis indicated that the LAD1 expression might be inversely linked to the immune cell infiltration degree, expression of the infiltrated immune cells, and the PD-L1 levels. Lastly, we supplemented some verification to increase the rigor of the study. The results suggested that high expression of LAD1 may be related to cold tumors. Hence, this indirectly reflects that the immunotherapy effect of LUAD patients with high LAD1 expression might be worse. Based on the role played by the LAD1 in the tumor immune microenvironment, it can be considered a potential biomarker for predicting the immunotherapy response to LUAD.

J Thorac Cardiovasc Surg 2023; 166:655-666.e7. [PMID: 36841745 DOI: 10.1016/j.jtcvs.2023.01.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Revised: 12/12/2022] [Accepted: 01/01/2023] [Indexed: 01/22/2023]
Abstract
OBJECTIVE Adjuvant atezolizumab is a standard of care after chemotherapy in completely resected stage II-IIIA programmed death ligand-1 tumor cell 1% or greater non-small cell lung cancer based on results from the phase III IMpower010 study. We explored the safety and tolerability of adjuvant atezolizumab by surgery type in IMpower010. METHODS Patients had completely resected stage IB-IIIA non-small cell lung cancer (Union Internationale Contre le Cancer/American Joint Committee on Cancer, 7th Ed), received up to four 21-day cycles of cisplatin-based chemotherapy, and were randomized 1:1 to receive atezolizumab 1200 mg every 3 weeks (≤16 cycles or 1 year) or best supportive care. Adverse events and clinical characteristics were investigated by surgery type (pneumonectomy/bilobectomy or lobectomy/sleeve lobectomy) in the randomized stage II-IIIA population who received 1 or more atezolizumab dose or with 1 or more postbaseline assessment (safety evaluable) for best supportive care. RESULTS Overall, 871 patients comprised the safety-evaluable randomized stage II-IIIA population. In the atezolizumab arm, 23% (100/433) received pneumonectomy/bilobectomy and 77% (332/433) received lobectomy/sleeve lobectomy. Atezolizumab discontinuation occurred in 32% (n = 32) and 35% (n = 115) of the pneumonectomy/bilobectomy and lobectomy/sleeve lobectomy groups, respectively. Grade 3/4 adverse events were reported in 21% (n = 21) and 23% (n = 76) of patients in the atezolizumab arms in the pneumonectomy/bilobectomy and lobectomy/sleeve lobectomy groups, respectively. In the atezolizumab arms of the surgery groups, 13% (n = 13) and 17% (n = 55) had an adverse event leading to hospitalization. Atezolizumab-related adverse events leading to hospitalization occurred in 5% (n = 5) and 7% (n = 23) of the surgery groups. CONCLUSIONS These exploratory findings support use of adjuvant atezolizumab after platinum-based chemotherapy in patients with completely resected stage II-IIIA programmed death ligand-1 tumor cell 1% or more non-small cell lung cancer, regardless of surgery type.

Abstract
OBJECTIVE To examine the efficacy of immune checkpoint inhibitors along with chemotherapy in non-small cell lung cancer (NSCLC) and the effect on adverse reactions and serum tumor markers. METHODS Data of 112 NSCLC patients admitted to Geriatric respiratory department, Xi'an International Medical Center Hospital from February 2018 to March 2021 were analyzed retrospectively. Among them, 54 patients treated with concurrent chemotherapy were labeled as the control group (CG), and 58 patients treated with PD-1/PD-L1 inhibitors in addition to chemotherapy were the observation group (OG). The two groups were compared in terms of immune function indexes, therapeutic efficacy, incidence of adverse reactions, 1-year survival rate, serum tumor markers before and after treatment, and independent risk factors affecting patients' prognosis. RESULTS Compared to the CG, the OG exhibited significantly better therapeutic efficacy. The levels of IgG, IgA and IgM 6 months after treatment were significantly higher in both groups than those before treatment, and the elevations in the OG were more evident than those in the CG, and the OG demonstrated markedly lower Recombinant Cytokeratin Fragment Antigen 21-1 (CYFRA21-1), Carcinoembryonic antigen (CEA) and Carbohydrate antigen 125 (CA125) levels after treatment than the CG did. Between the two groups, there was no significant difference identified in the incidence of adverse reactions, but the OG was observed to have much higher 1-year survival rate. The pathological stage, differentiation and treatment regimen were independent risk factors affecting patients' prognosis. CONCLUSION For NSCLC patients, the adoption of PD-1/PD-L1 inhibitors following chemoradiotherapy shows potential in enhancing clinical efficacy, boosting patients' immune function, and improving long-term survival rates, with premising safety profile.

Abstract
BACKGROUND The treatment and diagnosis of non-small cell lung cancer (NSCLC) is still a difficult problem in the medical community, and exploring the molecular mechanism of the occurrence and development of NSCLC is a hot topic of the current research. Long non-coding RNA (lncRNA) NORAD is highly expressed in a variety of cancer cells. It may be a molecular target that promotes NSCLC. The aim of this study was to investigate the impacts of lncRNA NORAD on the proliferation, apoptosis, and chemosensitivity of NSCLC by regulating zinc finger protein 217 (ZNF217) through miR-199a-3p. METHODS Real-time quantitative polymerase chain reaction (qRT-PCR) method was applied to detect the expressions of NORAD, miR-199a-3p and ZNF217 genes in normal lung epithelial cells BEAS-2B, lung cancer H460 cells, and Cisplatin (DDP) resistant cell lines H460/DDP. H460/DDP cells were devided into control group, si-NC group, si-NORAD group, miR-NC group, miR-199a-3p mimic group, si-NORAD+inhibitor NC group and si-NORAD+miR-199a-3p inhibitor group. Cell proliferation, apoptosis, the expression of NORAD, miR-199a-3p and ZNF217 genes of cells in each group were detected and the expression levels of Ki-67, caspase-9 and ZNF217 proteins in different cells were also observed. The relationship between miR-199a-3p, NORAD and ZNF217 was vefified. RESULTS Compared with BEAS-2B cells, the expressions of NORAD, ZNF217 mRNA were significantly increased in H460 and H460/DDP cells (P<0.05) but the expression of miR-199a-3p was significantly reduced (P<0.05). Compared with H460 cells, the expression of NORAD and ZNF217 mRNA in H460/DDP cells was significantly increased (P<0.05) and the expression of miR-199a-3p was significantly reduced (P<0.05). Compared with the control group and si-NC group, the proliferation rate, NORAD and ZNF217 mRNA expression, Ki-67 and ZNF217 protein expression of H460/DDP cells in the si-NORAD group were significantly reduced (P<0.05), but the apoptosis rate, miR-199a-3p expression and caspase-9 expression were significantly increased (P<0.05). Compared with the miR-NC group, the proliferation rate, NORAD and ZNF217 mRNA expression, Ki-67 and ZNF217 protein expression of H460/DDP cells in the miR-199a-3p mimic group were significantly reduced (P<0.05), but the apoptosis rate, miR-199a-3p expression and caspase-9 expression were significantly increased (P<0.05). Compared with the si-NORAD+inhibitor NC group, the proliferation rate, ZNF217 mRNA expression, Ki-67 and ZNF217 protein expression of H460/DDP cells in the si-NORAD+miR-199a-3p inhibitor group were significantly increased (P<0.05), the apoptosis rate, miR-199a-3p expression and caspase-9 expression were obviously increased reduced (P<0.05). CONCLUSIONS Down-regulating NORAD expression can enhance miR-199a-3p expression and inhibit ZNF217 expression, thereby inhibiting H460/DDP cell proliferation, promoting apoptosis and enhancing its DDP chemotherapy sensitivity.

Biomedicines 2023; 11:2011. [PMID: 37509650 PMCID: PMC10376976 DOI: 10.3390/biomedicines11072011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 07/12/2023] [Accepted: 07/14/2023] [Indexed: 07/30/2023] Open
Abstract
Tumor angiogenesis and lymphangiogenesis pathways have been identified as important therapeutic targets in non-small cell lung cancer (NSCLC). Bevacizumab, which is a monoclonal antibody, was the initial inhibitor of angiogenesis and lymphangiogenesis that received approval for use in the treatment of advanced non-small cell lung cancer (NSCLC) in combination with chemotherapy. Despite its usage, patients may still develop resistance to the treatment, which can be attributed to various histological subtypes and the initiation of treatment at advanced stages of cancer. Due to their better specificity, selectivity, and safety compared to chemotherapy, small molecules have been approved for treating advanced NSCLC. Based on the development of multiple small-molecule antiangiogenic drugs either in house and abroad or in other laboratories to treat NSCLC, we used a quinoline-derived small molecule-HN-N07-as a potential target drug for NSCLC. Accordingly, we used computational simulation tools and evaluated the drug-likeness properties of HN-N07. Moreover, we identified target genes, resulting in the discovery of the target BIRC5/HIF1A/FLT4 pro-angiogenic genes. Furthermore, we used in silico molecular docking analysis to determine whether HN-N07 could potentially inhibit BIRC5/HIF1A/FLT4. Interestingly, the results of docking HN-N07 with the BIRC5, FLT4, and HIF1A oncogenes revealed unique binding affinities, which were significantly higher than those of standard inhibitors. In summary, these results indicate that HN-N07 shows promise as a potential inhibitor of oncogenic signaling pathways in NSCLC. Ongoing studies that involve in vitro experiments and in vivo investigations using tumor-bearing mice are in progress, aiming to evaluate the therapeutic effectiveness of the HN-N07 small molecule.

Abstract
Research on biomarker-driven therapy and immune check-point blockade in non-small cell lung cancer (NSCLC) is rapidly evolving. The width and depth of clinical trials have also dramatically improved in an unprecedented speed. The personalized treatment paradigm evolved every year. In this review, we summarize the promising agents that have shifted the treatment paradigm for NSCLC patients across all stages, including targeted therapy and immunotherapy using checkpoint inhibitors. Based on recent evidence, we propose treatment algorithms for NSCLC and propose several unsolved clinical issues, which are being explored in ongoing clinical trials. The results of these trials are likely to impact future clinical practice.

A Propensity-Matched Retrospective Comparative Study with Historical Control to Determine the Real-World Effectiveness of Durvalumab after Concurrent Chemoradiotherapy in Unresectable Stage III Non-Small Cell Lung Cancer. Cancers (Basel) 2023; 15:cancers15051606.

Abstract
This study aimed to add real-world evidence to the literature regarding the effectiveness and safety of durvalumab consolidation (DC) after concurrent chemoradiotherapy (CCRT) in the treatment of unresectable stage III non-small cell lung cancer (NSCLC). Using a hospital-based NSCLC patient registry and propensity score matching in a 2:1 ratio, we conducted a retrospective cohort study of patients with unresectable stage III NSCLC who completed CCRT with and without DC. The co-primary endpoints were 2-year progression-free survival and overall survival. For the safety evaluation, we evaluated the risk of any adverse events requiring systemic antibiotics or steroids. Of 386 eligible patients, 222 patients-including 74 in the DC group-were included in the analysis after propensity score matching. Compared with CCRT alone, CCRT with DC was associated with increased progression-free survival (median: 13.3 vs. 7.6 months, hazard ratio[HR]: 0.63, 95% confidence interval[CI]: 0.42-0.96) and overall survival (HR: 0.47, 95% CI: 0.27-0.82) without an increased risk of adverse events requiring systemic antibiotics or steroids. While there were differences in patient characteristics between the present real-world study and the pivotal randomized controlled trial, we demonstrated significant survival benefits and tolerable safety with DC after the completion of CCRT.

PURPOSE Concurrent chemotherapy and radiotherapy treatment (CCRT) is used to treat locally advanced Non-Small Cell Lung Cancer (NSCLC) in patients with suitable fitness. CCRT is associated with significant toxicity and time spent receiving treatment. Our aim was to identify the support and information needs of patients, and where possible their informal caregivers (IC), at key points along the CCRT pathway. METHODS Participants were NSCLC patients who were either about to undergo, currently receiving or had finished CCRT. Semi-structured interviews were conducted with participants, and their IC where applicable, at the treatment centre or participants' home. Interviews were audio recorded and transcribed prior to undergoing thematic analysis. RESULTS Fifteen patients were interviewed; five were interviewed with their IC. Themes of physical, psychological, and practical support needs are identified with associated subthemes exploring specific needs, such as dealing with late treatment effects, and how patients seek support. Information needs prior to, during and following CCRT were also established as predominant themes with subthemes detailing the needs at these time points. Examples include differences in participant desire for toxicity information and life after treatment. CONCLUSIONS The need for disease, treatment and symptom related information and support remains consistent throughout CCRT and beyond. Further information and support for other matters including engaging in regular activities may also be desired. Time allocated within consultations to establish changes in needs or desire for further information may benefit patient and IC experience and QOL.

Arsenic trioxide elicits anti-tumor activity by inhibiting polarization of M2-like tumor-associated macrophages via Notch signaling pathway in lung adenocarcinoma.

Abstract
Drug-resistant advanced lung adenocarcinoma (LUAD) is an aggressive malignancy with limited treatment options. A therapeutic strategy for drug-resistant LUAD is to target the tumor associated macrophages (TAMs), because they play an important role in tumor immune escape, progression and metastasis. In this study, we conducted in vivo and in vitro investigation of the inhibitory effect of arsenic trioxide (ATO) on polarization of TAMs educated by LUAD. We found that ATO at a concentration of 4 μM disrupted the Notch-dependent positive feedback loop between LUAD and TAMs. In this loop, ATO inhibited the expression of Jagged1 and Notch1 in LUAD and suppressed M2 polarization via down-regulating Notch-dependent paracrine of CCL2 and IL1β. As a result, the secretion of M2-derived TGF-β1 decreased, thus inducing inhibitions of LUAD proliferation, migration, invasion, colony formation and epithelial-mesenchymal transition. In xenograft mouse models, ATO significantly inhibited tumor growth and down-regulated infiltration of M2-like TAMs in tumor tissues. In clinical LUAD biopsy samples, high Jagged1/Notch1 expression positively correlated with tumor-infiltrated M2-like TAMs, leading to poor prognosis. In conclusion, our results identified a novel tumor immunomodulating function for ATO, which can inhibit the polarization of M2-type TAMs to exert anti-tumor effects in the tumor microenvironment. Our results demonstrated the translational potential of repurposing ATO to target TAMs for lung adenocarcinoma treatment.

Abstract
Extended lung resections for T3-T4 non-small-cell lung cancer remain challenging. Multimodal management is mandatory in multidisciplinary tumor boards, and here the determination of resectability is key. Long-term oncologic efficacy depends mostly on complete resection (R0) and the extent of N2 disease. The development of novel innovative treatments (targeted therapy and immune checkpoint inhibitors) sets interesting perspectives to reinforce current therapeutic options in the induction and adjuvant setting.

Abstract
Background Cisplatin (DDP) is among the most widely used chemotherapeutic drugs for non-small cell lung cancer (NSCLC), yet the frequent emergence of chemoresistance serves as a major barrier to the treatment of this tumor type. Long non-coding RNAs (lncRNAs) have recently been shown to influence the ability of cells to resist particular chemotherapy drugs. The present study was developed to explore the role of the lncRNA SNHG7 as a regulator of NSCLC cell chemosensitivity. Methods Quantitative real-time polymerase chain reaction (qRT-PCR) was employed to measure SNHG7 expression in NSCLC tissues from patients that were sensitive/resistant to DDP, correlations between SNHG7 expression levels and the patients' clinicopathological characteristics were assessed, and the prognostic relevance of SNHG7 expression was examined via the Kaplan-Meier approach. In addition, SNHG7 expression was assessed in NSCLC cell lines that were DDP-sensitive or -resistant, while western blotting and immunofluorescence staining were employed to detect autophagy-associated protein expression in A549, A549/DDP, HCC827, and HCC827/DDP cells. NSCLC cell chemoresistance was quantified via the Cell Counting Kit-8 (CCK-8) assay approach, and flow cytometry was used to detect the apoptotic death of these tumor cells. The chemosensitivity of xenograft tumors in vivo was further assessed to validate the functional importance of SNHG7 as a regulator of NSCLC DDP resistance. Results Relative to paracancerous tissues, NSCLC tumors exhibited SNHG7 upregulation, and this lncRNA was further upregulated in DDP-resistant patients compared to chemosensitive patients. Consistently, higher SNHG7 expression levels were correlated with worse patient survival outcomes. DDP-resistant NSCLC cells were also found to exhibit higher levels of SNHG7 expression than chemosensitive cells, and knocking down this lncRNA enhanced the sensitivity of these cells to DDP treatment, resulting in impaired proliferation and higher rates of apoptotic death. Knocking down SNHG7 was also sufficient to suppress microtubule associated protein 1 light chain 3 beta (LC3B) and Beclin1 protein levels and promote p62 upregulation in vitro. The silencing of this lncRNA additionally inhibited the resistance of NSCLC xenograft tumors to DDP treatment in vivo. Conclusions SNHG7 can promote malignant behaviors and DDP resistance in NSCLC cells at least partly via the induction of autophagic activity.

Effectiveness of neoadjuvant immunochemotherapy compared to neoadjuvant chemotherapy in non-small cell lung cancer patients: Real-world data of a retrospective, dual-center study. Front Oncol 2023; 13:1145303. [PMID: 37064108 PMCID: PMC10098217 DOI: 10.3389/fonc.2023.1145303] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Accepted: 03/20/2023] [Indexed: 04/18/2023] Open
Abstract
Background Studying the application of neoadjuvant immunochemotherapy (NICT) in the real world and evaluating its effectiveness and safety in comparison with neoadjuvant chemotherapy (NCT) are critically important. Methods This study included the II-IIIB stage non-small cell lung cancer (NSCLC) patients receiving NCT with or without PD-1 inhibitors and undergoing surgery after neoadjuvant treatments between January 2019 to August 2022. The clinical characteristics and treatment outcomes were retrospectively reviewed and analyzed. Results A total of 66 patients receiving NICT and 101 patients receiving NCT were included in this study. As compared to NCT, NICT showed similar safety while not increasing the surgical difficulty. The ORR in the NICT and NCT groups was 74.2% and 53.5%, respectively, P = 0.009. A total of 44 patients (66.7%) in the NICT group and 21 patients (20.8%) in the NCT group showed major pathology response (MPR) (P <0.001). The pathology complete response (pCR) rate was also significantly higher in NICT group than that in NCT group (45.5% vs. 10.9%, P <0.001). After Propensity Score Matching (PSM), 42 pairs of patients were included in the analysis. The results showed no significant difference in the ORR between the two groups (52.3% vs. 43.2%, P = 0.118), and the proportions of MPR (76.2%) and pCR (50.0%) in NICT group were significantly higher than those of MPR (11.9%) and pCR (4.7%) in the NCT group (P <0.001). The patients with driver mutations might also benefit from NICT. Conclusions As compared to NCT, the NICT could significantly increase the proportions of patients with pCR and MPR without increasing the operation-related bleeding and operation time.

Abstract
INTRODUCTION Age-related disparities in non-small cell lung cancer (NSCLC) treatment are well known, but few studies have assessed the impact of sex on treatment disparities. Disparities in guideline-adherence may explain the superior survival in women with NSCLC. Therefore, we aimed to define patient- and tumor-related factors associated with non-adherence to guidelines in NSCLC management with a special focus on sex and age. PATIENTS AND METHODS Patients with NSCLC who received first-line treatment at the Vaasa Central Hospital between 2016 and 2020 were included in the study. The primary outcome was guideline adherence, defined as adherent, undertreatment, or overtreatment considering performance status. A binary logistic regression model was used to calculate the adjusted odds ratio (aOR) for non-adherence to treatment guidelines depending on patient- and tumor-related factors. RESULTS 321 patients were included in the study. Non-adherence was highest in ≥75-year-old women (41.3%), followed by ≥75-year-old men (32.6%), <75-year-old men (27.6%) and lowest in women <75-year-old (19.7%) (p = 0.035). Non-adherent care consisted more often of undertreatment in <75-year-old men than women (26.0% versus 12.1%) and overtreatment in <75-year-old women than men (7.6% versus 1.6%). Non-adherence was associated with stage III disease (aOR 2.21; 95% CI 1.07-4.59), poor pulmonary function (aOR 3.69, 95% CI 1.56-8.71), and Charlson Comorbidity Index 1-2 (aOR 2.09; 95% CI 1.09-4.01). CONCLUSION Sex- and age-related disparities in guideline adherence were observed in <75-year-old men and in ≥75-year-olds. Stage III NSCLC was associated with non-adherence.

Abstract
The controversy over the efficacy of postoperative radiotherapy (PORT) has existed for a long time. The present study reassessed the overall survival (OS) and disease-free survival (DFS) data to investigate whether PORT can improve survival in resectable non-small cell lung cancer (NSCLC) patients. The following databases were used to perform literature search: PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), and Embase (from January 1, 1986 to July 5, 2021). The results of overall survival (OS) and disease-free survival (DFS) were calculated as hazard ratio (HR). Confidence intervals are chosen with 95% confidence intervals. A total of 12 RCTs and 19 retrospective cohort studies were found to meet the inclusion criteria. A significant DFS improvement was detected in the PORT group (4111 patients from 15 studies), although statistical difference was not detected for OS between the non-PORT and PORT groups (31 studies, 49,342 total patients). PORT prolonged OS in patients undergoing PORT plus postoperative chemotherapy (POCT) and in pN2 patients. Patients with a median radiation dose of 50.4 Gy and a median radiation dose of 54 Gy had a better OS after PORT. However, if the total radiotherapy dose went up to 60 Gy, PORT increased the risk of death in NSCLC patients. Significant difference in OS was not found in the results of studies with regard to treatment methods, pathologic stages, study type, radiation beam quality, and radiation dose. Patients undergoing postoperative chemoradiotherapy and pN2 patients can benefit from PORT. Patients exposed to median radiation doses of 50.4 and 54 Gy demonstrated relatively good efficacy. For patients with non-small-cell lung cancer, PORT has not been proven to extend OS, but its effect on DFS remains strong.

Abstract
Lung adenocarcinoma (LUAD) is the most common histological subtype of lung cancer. In the development and progression of LUAD, epigenetic aberration plays a crucial role. However, the function of RNA N6-methyladenosine (m6A) modifications in the LUAD progression is unknown. The m6A regulator modification patterns in 955 LUAD samples were analyzed comprehensively. Patterns were systematically correlated with the tumor microenvironment (TME) cell-infiltration characteristics. Using principal component analysis algorithms, the m6Ascore was generated to quantify m6A modification patterns in individual tumors. Then, their values for predicting prognoses and therapeutic response in LUAD patients were assessed. Three distinct m6A modification patterns in LUAD were identified. Among them, the prognosis of m6Acluster C was the best, while the prognosis of m6Acluster A was the worst. Interestingly, the characterization of TME cell infiltration and biological behavior differed among the three patterns. To evaluate m6A modification patterns within individual tumors, an m6Ascore signature was constructed. The results showed that the high m6Ascore group was associated with a better prognosis; tumor somatic mutations and tumor microenvironment differed significantly between the high- and low- m6Ascore groups. Furthermore, in the cohort with anti-CTLA-4 treatment alone, patients with a high m6Ascore had higher ICI scores, which indicated significant therapeutic advantage and clinical benefits.

Abstract
Non-small cell lung cancer (NSCLC) accounts for 75-80% of all lung cancer cases. Stage III NSCLC represents a highly heterogenous stage characterized by different disease presentations and a wide range of treatment options. For patients with good performance status and unresectable-stage III NSCLC with programmed death-ligands 1 (PD-L1) tumor proportion score (TPS) ≥1%, durvalumab consolidation immunotherapy after a platinum-based chemo-radiotherapy is strongly recommended. However, age, poor performance status, underlying comorbidities may represent contraindications for chemotherapy to be used in a subgroup of patients. Herein, we report a case of an 80-year-old male affected by a stage IIIB lung adenocarcinoma with overexpression of PD-L1 (TPS 90%) treated with pembrolizumab, an immune checkpoint inhibitor targeting PD-1/PD-L1 pathways, which shows a complete resolution of lung lesion after four cycles of treatment. Although randomized controlled trials are required, this case report may suggest the potential role of pembrolizumab for chemotherapy unsuitable patients with overexpressing PD-L1 unresectable-stage III NSCLC.

Abstract
The prognosis of patients with stage IIIC non-small-cell lung cancer (NSCLC) is poor due to the loss of surgical treatment opportunities. Improving the prognosis of these patients with IIIC NSCLC urgently needs to be addressed. Here, we report a stage IIIC (T4N3M0 IIIC (AJCC 8th)) NSCLC patient treated with 2 cycles of anti-PD-1 immunotherapy combined with chemotherapy and anti-angiogenesis therapy; after two cycles of treatment, the patient achieved a partial response and obtained the opportunity for surgical treatment. After the operation, the patient achieved a pathological complete response and successfully transformed from unresectable stage IIIC lung cancer to radical surgery (ypT0N0M0). Our study is expected to provide new ideas for treating patients with unresectable stage IIIC NSCLC in the future.

Abstract
Background: Forkhead box P (FOXP) family was introduced as a double-edged sword in tumorigenesis and influenced immunotherapy response by modulating host immunity. This study aimed to summarize the involvement of the FOXP family in non-small cell lung cancer (NSCLC).Methods: The UALCAN, Gene Expression Profiling Interactive Analysis (GEPIA), and Reverse transcription-quantitative polymerase chain reaction (RT‒qPCR) were used to analyse the expression levels of the FOXP family in NSCLC. The prognostic impact was evaluated using Kaplan-Meier Plotter. MethSurv, UALCAN, and cBioPortal were applied to analyse the DNA methylation and mutation status of the FOXP family respectively. COEXPEDIA, STRING, and GeneMANIA were used to explore the interaction mechanism. Finally, TISIDB was used to investigate all of the immune-related characteristics regulated by the FOXP family.Results: The expression levels of FOXP1/3/4 were dysregulated in NSCLC tissues than that in normal tissues. Groups with low expression levels of FOXP1/4 and high expression levels of FOXP2/3 were associated with poor prognosis in NSCLC. The transcriptional levels of FOXP2/3/4 were correlated with DNA methylation in NSCLC. FOXP1/3/4 DNA methylation were correlated with prognosis. Pathway enrichment analysis indicated the FOXP family was mainly related to immune-related pathways. After DNA methylation, the correlations between FOXP family and immune factors were opposite to that before alteration in NSCLC.Conclusion: This study elucidated FOXP family could serve as vital diagnostic and prognostic biomarkers in NSCLC. Our study highlighted novel potential functions of FOXP family DNA methylation in regulation of immune-related signatures in NSCLC.

Abstract
Abstract
Background
This analysis presents the outcomes of the operations of the National Cancer Network (NCN) pilot project in Lower Silesian Voivodeship, Poland, for lung cancer for the period of 2019–2021. The results concerning measures of the quality of medical processes were analysed.
Methods
Twenty-one measures used to gauge the quality of oncological care for lung cancer were assessed. Data collection and processing for the purpose of calculating the measures were carried out as part of the NCN pilot project based on the Regulation of the Ministry of Health enacted on 13 December 2018. The measures were calculated at the Voivodeship Coordination Center, and the data were derived from the centres included in the network in the area of the analysed voivodeship.
Results
A total of 3,638 patients diagnosed with lung cancer were enrolled in the NCN pilot program during the analysed period. For 3 measures, out of 21, target values were obtained. For 2 measures, the values differed significantly from the assumed target value.
Conclusion
In our opinion, the NCN pilot study, as a test of the network’s functioning, meets the assumed goal. The NCN assessment is based on, inter alia, analysis of the outcomes of oncological quality of care measures for lung cancer, and facilitates monitoring of the quality of medical services provided and the identification of areas for improvement. In addition, the pilot program, which will last until the end of 2022, will allow for further in-depth analysis regarding the network’s limitations before implementing the system on a national scale in Poland. This will be the subject of further investigation.

Abstract
Nonsmall cell lung cancer (NSCLC) is a serious threat to the life and health of patients with high incidence rate and mortality. The present research was to assess the relationship between the serum Krüppel-like factor 7 (KLF7) level and the recurrence and metastasis of NSCLC patients. 150 patients with NSCLC treated by thoracoscopic radical resection of lung cancer in our hospital from January 2016 to February 2017 were selected. As the control group, 148 healthy people who went to the hospital for physical examination in the same period were screened. The expression levels of serum KLF7 in the observation group and the control group were compared and analyzed. According to the level of KLF7 expression, the patients in the observation group were divided into KLF7 high expression group (≥258.6 ng/L, n =75) and KLF7 low expression group (<258.6 ng/L, n =75). The 3-year recurrence and metastasis rate of patients in each group was compared and analyzed. It was found the concentration of serum KLF7 in peripheral blood of NSCLC (2.25 ± 0.65) ng/ml was significantly higher than that in healthy population (1.42 ± 0.38) ng/ml (P < 0.05). The expression level of serum KLF7 was not related to gender, age, smoking history, and tumor diameter of NSCLC patients (P > 0.05), but related to the degree of differentiation and TNM stage of NSCLC patients (P < 0.05). Univariate analysis showed that the degree of differentiation, TNM stage, and KLF7 were significantly correlated with 3-year recurrence and metastasis of NSCLC patients (P < 0.05). Cox regression analysis showed that low degree of differentiation, TNM stage IIIa, and KLF7 were independent risk factors for recurrence and metastasis in NSCLC patients in 3 years (P < 0.05). Taken together, the expression level of serum KLF7 in patients with NSCLC is significantly increased, which is an independent risk factor for recurrence and metastasis in 3 years, and is worthy of clinical application.

TRIM66 Promotes Malignant Progression of Non-Small-Cell Lung Cancer Cells via Targeting MMP9. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:6058720. [PMID: 35912155 PMCID: PMC9334090 DOI: 10.1155/2022/6058720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Revised: 07/01/2022] [Accepted: 07/07/2022] [Indexed: 12/24/2022]
Abstract
Lung cancer has a higher incidence and mortality rate than other cancers, and over 80% of lung cancer cases were classified as non-small-cell lung cancer (NSCLC). TRIM66 is one of the crucial members of TRIM, which has a deep connection with the behavior of various malignant tumors. But it remains uncertain regarding its exact function and underlying mechanism in NSCLC. In our study, qRT-PCR and Western blot were employed to validate that TRIM66 was overexpressed in NSCLC. The migration, invasion, and epithelial-mesenchymal transformation (EMT) progression of NSCLC cells were determined by Western blotting and Transwell experiments after knocking down TRIM66, and it was found that knockdown TRIM66 inhibited the migration, invasion, and EMT processes of NSCLC cells. Next, the binding relationship between TRIM66 and MMP9 was verified by Co-IP assay. After determining the interaction between them, rescue assays showed that overexpression of MMP9 was capable to promote the migration, invasion, and EMT of NSCLC cells. However, the transfection of si-TRIM66 could reverse this facilitating effectiveness. To sum up, we concluded that by targeting MMP9, TRIM66 could exert a cancer-promoting role in the progression of NSCLC cells.

Abstract
BackgroundRecently, immunotherapy (IO) has shown striking survival improvement in unresectable stage III non-small cell lung cancer (NSCLC). However, the role of chemo-radiotherapy (CRT) for improvement in outcomes should not be disregarded. This study aimed to compare the treatment patterns and illustrate the impact of radiotherapy on the cancer-specific survival (CSS) and overall survival (OS) of patients with unresected locally advanced stage III NSCLC.MethodsWe retrospectively analyzed the data of patients with stage III NSCLC patients who did not undergo surgery from the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) database between 2001 and 2016, and three continuous years were regarded as one unit. Using the Kaplan-Meier method, we identified the CSS and OS. Then, a linear regression model was graphed to analyze the correlation between median survival of CSS or OS and calendar years in the radiotherapy alone, chemotherapy alone, and CRT groups.ResultsA total of 20986 patients were included in this study. In the overall cohort, CSS and OS improved consistently. To explore the reason for the improved survival, patients were divided into three different cohorts: radiotherapy alone, chemotherapy alone, and CRT. From 2001 to 2015, the median CSS improved persistently, 7, 8, 8, 9, and 11 months in the radiotherapy alone group and 12, 13, 15, 17, 19 months in the CRT group, but improvement in outcomes was less consistent in the chemotherapy alone group (10, 9, 11, 12, 12 months). To better visualize the correlation between CSS and calendar year, linear regression was performed, yielding r2 = 0.8032, P = 0.0395 for the radiotherapy alone group; r2 = 0.7206, P = 0.0689 for the chemotherapy alone group; and r2 = 0.9878, P = 0.0006 for the CRT group. Similar findings were observed in the OS data. In addition to this, we also analyzed different pathological types and also obtained the same results.ConclusionsThe survival of patients with unresectable stage III NSCLC has improved substantially, and the most pronounced and consistent improvements were observed in the CRT group. In addition to IO, radiotherapy played an essential role in the treatment of unresectable stage III NSCLC in the past years and should be considered in the design of clinical trials.

Abstract
Immune evasion is the process that tumor cells accelerate growth and metastasis by evading the recognition and attack of immune cells. SNF5 is one of the core subunits of SWI/SNF, which is involved in the development of a variety of malignancies. However, the functions of SNF5 in Non-Small Cell Lung Cancer (NSCLC) and the mechanism of SNF5 regulates immune evasion are still unclear. Based on this, we analyzed the expression of SNF5 and overall survival of lung cancer tissues through the cancer genome atlas (TCGA) database. Then we performed genetic gain and loss of function experiments with SNF5 using lentivirus infection and siRNA in NSCLC A549 and NCI-H1299 cells, respectively. We investigated the proliferation and immune evasion of these cells. We further explored the mechanism of SNF5 on NSCLC cells immune evasion. Our data showed that SNF5 was significantly increased in lung cancer tissues than that in normal lung tissues. Furthermore, SNF5 promoted NSCLC cells proliferation and the expressions of immune evasion-related genes. Meantime, overexpressed SNF5 reduced mortality of A549 cells when co-cultured with T cells. Moreover, SNF5 regulated the immune evasion by activating the signal transducer and activator of transcription (STAT3)/ phospho-STAT3 pathway in NSCLC cells. Together, our results validate SNF5 as a tumor oncogene and provide a new target for NSCLC treatment.

Abstract
Abstract:
Integrins are a class of a cell surface adhesion molecule which composed of α subunit (ITGA) and β subunit (ITGB). They belong to heterodimer transmembrane glycoproteins. Its main function in organisms is as the receptor of cell adhesion molecules (CAMs) and extracellular matrix (ECM). According to the current research integration analysis, integrin α9 (ITGA9) is one of the integrin subunits, and there are few studies on ITGA9 among integrins. ITGA9 can improve cell migration and regulate various cellular biological functions, such as tumor cell proliferation, adhesion, invasion, and angiogenesis. But its abnormal expression mechanism in cancer and its specific role in tumor growth and metastasis are still unknown to a great extent. This review reveals the role of ITGA9 in the complex pathogenesis of many tumors and cancers, providing a new direction for the treatment of tumors and cancers. Relevant studies were retrieved and collected through the PubMed system. After determining ITGA9 as the research object, we found the close relationship between ITGA9 and tumorigenesis through the analysis of the research articles on ITGA9 in the PubMed system in the last 15 years, and further determined the references mainly based on the influencing factors of the articles. Thus, the role of ITGA9 in tumor and cancer genesis, proliferation, and metastasis was reviewed and analyzed.
ITGA9 is an integrin subunit, which has been proved to be abnormally expressed in many tumors. After sorting and analyzing the research data, it was found that the abnormal expression of ITGA9 in a variety of tumors, including glioblastoma, rhabdomyosarcoma, melanoma, hepatocellular carcinoma, nasopharyngeal carcinoma, multiple myeloma, non-small cell lung cancer, and prostate cancer, was closely related to the proliferation, metastasis, adhesion, and angiogenesis of tumor cells. These results suggest that ITGA9 plays an important role in the occurrence and development of tumors. The integrin subunit ITGA9 may serve as a biomarker for the diagnosis of tumors and a potential therapeutic target for anti-tumor therapies.

Abstract
Low-density lipoprotein receptor-related protein 8 (LRP8) is involved in the development of multiple tumors, including lung cancer. However, the exact mechanism by which LRP8 exerts its oncogenic role in non-small cell lung cancer (NSCLC) remains elusive. Hence, in this study, we aimed to unravel the expression and role of LRP8 in the progression of NSCLC. We used online bioinformatics databases to identify the expression of LRP8 in multiple types of lung cancer. We validated LRP8 expression in NSCLC cell lines and tissues by Western blotting and immunohistochemistry. The functions of LRP8 in NSCLC carcinogenesis and progression were determined using in vitro and in vivo systems. The Wnt pathway activator LiCl was further used to validate the regulatory role of LRP8 in Wnt/β-catenin signaling. We demonstrated that LRP8 was markedly overexpressed in NSCLC tissues and cell lines, and its overexpression significantly correlated with poor clinicopathological characteristics and prognosis. Moreover, LRP8 depletion suppressed cell proliferation, migration, invasion, and epithelial-mesenchymal transition in vitro and impeded tumor growth in vivo. Mechanistically, LPR8 knockdown elicited tumor-suppressive functions by suppressing the Wnt/β-catenin pathway, which was partially reversed by LiCl. Hence, our study revealed that LRP8 facilitates NSCLC cell proliferation and invasion via the Wnt/β-catenin pathway, and thus LRP8 could be a novel therapeutic target for NSCLC.

Real-world Perspectives from Surgeons and Oncologists on Resectability Definition and Multidisciplinary Team Discussion of Stage III NSCLC in China, Hong Kong and Macau: A Physician Survey. JTO Clin Res Rep 2022; 3:100308. [PMID: 35434668 PMCID: PMC9011118 DOI: 10.1016/j.jtocrr.2022.100308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Revised: 03/03/2022] [Accepted: 03/06/2022] [Indexed: 11/24/2022] Open
Abstract
Introduction Decision-making in diagnosis and management of stage III NSCLC remains complex owing to disease heterogeneity and diverse treatment options, and often warrants multidisciplinary team discussion. Specifically, the selection of patients for multimodality approaches involving surgical resection presents notable challenges owing to heterogeneity in guideline definitions and the subjective, case-specific nature of evaluating resectability on the basis of preoperative assessments. Methods An internet- and paper-based survey was conducted in 2020 among lung cancer specialists in the People’s Republic of China, Hong Kong, and Macau. This survey captured perspectives on stage III NSCLC on real-world diagnosis/staging practice, definition and evaluation of resectability using case scenarios, and preferred treatment paradigms. Results A total of 60 completed responses were obtained (60.0% surgeons; 40.0% oncologists). The surgeons’ and oncologists’ responses differed most in the assessment of resectability in specific case scenarios despite overall agreement on top factors determining resectability (T stage, lymph node size, and lymph node location). Of the 17 scenarios, specialists agreed (≥80%) on four “resectable” and six “unresectable” scenarios; of the seven scenarios with less than 80% agreement, surgeons and oncologists had diverging responses for six scenarios. Multidisciplinary team discussions were available in most of the respondents’ institutions but usually covered only selected (<50%) stage III cases. Conclusions This survey used a comprehensive set of stage III NSCLC case scenarios to understand how working definitions of resectability may differ between surgeons and oncologists, and thus, identify types of cases to prioritize for multidisciplinary discussions to maximize limited resources. In parallel, the development of a multidisciplinary expert consensus on treatment approaches could complement local institutional expertise as a reference for decision-making.

Case Report and Literature Review: Diagnosis, Tailored Genetic Counseling and Cancer Prevention for a Locally Advanced dMMR/MSI-H/TMB-H Lung Cancer Patient With Concurrent Lynch Syndrome Mediated by a Rare PMS2 Splicing Variant (c.1144+1G>A). Front Genet 2022; 12:799807.

Abstract
Lynch syndrome (LS) is a cancer-predisposing genetic disease mediated by pathogenic mutations in DNA mismatch repair (MMR) genes MLH1, MSH2, MSH6, and PMS2. Accumulating evidence demonstrates that there is significant biological heterogeneity across MMR genes. Compared to MLH1 and MSH2, PMS2 variant carriers have a much lower risk for LS-related cancers. Tumors in MLH1 and MSH2 variant carriers often display MMR deficiency (dMMR) and/or high microsatellite instability (MSI-H), two predictive biomarkers for immunotherapy efficacy. However, tumors in PMS2 variant carriers are largely microsatellite stable (MSS) instead of MSI. Therefore, the optimal management of cancer patients with LS requires the integration of disease stage, MMR gene penetrance, dMMR/MSI status, and tumor mutational burden (TMB). In this work, we presented a locally advanced lung cancer patient with dMMR/MSI-H/TMB-H tumor and selective loss of PMS2 by immunohistochemistry. Germline testing revealed a rare PMS2 splicing variant (c.1144+1G>A) in the proband and his healthy daughter. The diagnosis of LS was made based on genetic analysis of this variant and literature review. Given the incomplete penetrance of PMS2, the proband and the carrier received tailored genetic counseling. To reduce cancer risk, the proband received four cycles of nivolumab plus chemotherapy and achieved a disease-free survival of sixteen months.

Abstract
Purpose Lung cancer relapse may be associated with the presence of a small population of cancer stem cells (CSCs) with unlimited proliferative potential. Our study assessed the relationship between CSCs and the relapse rate in patients harboring adenocarcinoma (ADL) and squamous cell carcinoma of the lung (SCCL). Experimental design This is an observational prospective cohort study (NCT04634630) assessing the influence of CSC frequency on relapse rate after major lung resection in 35 patients harboring early (I-II) (n = 21) and locally advanced (IIIA) (n = 14) ADL and SCCL. There was a 2-year enrollment period followed by a 1-year follow-up period. Surgical tumor specimens were processed, and CSCs were quantified by cytofluorimetric analysis. Results Cancer stem cells were expressed in all patients with a median of 3.1% of the primary cell culture. Primary analysis showed no influence of CSC frequency on the risk of relapse (hazard ratio [HR] = 1.05, 95% confidence interval [CI] = 0.85-1.30). At secondary analysis, patients with locally advanced disease with higher CSC frequency had an increased risk of relapse (HR = 1.26, 95% CI = 1.14-1.39), whereas this was not observed in early-stage patients (HR = 0.90, 95% CI = 0.65-1.25). Conclusion No association was found between CSC and relapse rates after major lung resection in patients harboring ACL and SCCL. However, in locally advanced-stage patients, a positive correlation was observed between CSC frequency and risk of relapse. These results indicate a need for further molecular investigations into the prognostic role of CSCs at different lung cancer stages. Clinical Trial Registration NCT04634630.

Abstract
Circular RNA (circRNA) presents an essential regulatory role in affecting the occurrence and acquired resistance in non-small cell lung cancer (NSCLC), but how circSOX13 impacts NSCLC is unclear. In this work it was found that compared with adjacent normal tissues, circSOX13 and the microtubule-associated protein RP/EB family member 1 (MAPRE1) were signally up-regulated in NSCLC while miR-3194-3p was signally lowered. Pulmonary function tests (PETs) revealed that knocking down circSOX13 or overexpressing miR-3194-3p inhibited NSCLC proliferation, invasion and migration but promoted its apoptosis. The promoting effect of overexpressing circSOX13 on NSCLC was reversed via knocking down MAPRE1. Additionally, knocking down circSOX13 reduced cisplatin resistance in NSCLC. Furthermore, circSOX13 mediated MAPRE1 expression via competitively binding miR-3194-3p to exert its tumorigenic impact. To conclude, this work clarified the carcinogenic impact of circSOX13-miR-3194-3p-MAPRE1 axis on NSCLC and DDP resistance. CircSOX13 can be a potential diagnostic marker and therapeutic target for NSCLC, thus providing a new insight for clinically reversing its acquired resistance.

Yan J, Wan D. Dysregulation of circulating CDC42 and its correlation with demographic characteristics, comorbidities, tumor features, chemotherapeutic regimen and survival profile in non-small-cell lung cancer patients. J Clin Lab Anal 2021; 36:e24140. [PMID: 34952984 DOI: 10.1002/jcla.24140] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Revised: 11/09/2021] [Accepted: 11/13/2021] [Indexed: 01/28/2023] Open
Abstract
OBJECTIVE Cell division control protein 42 (CDC42) induces the immune escape, represses the CD8+ T-cell activation, and further leads to the tumor metastasis in various neoplasms, whereas the correlation of circulating CDC42 with clinical features and prognosis of non-small-cell lung cancer (NSCLC) remains elusive. Hence, the current study aimed to investigate this topic. METHODS Peripheral blood mononuclear cells from 263 NSCLC patients before treatment and 50 health controls (HC) were used for CDC42 determination by reverse transcription quantitative polymerase chain reaction (RT-qPCR) assay. RESULTS CDC42 expression was higher in NSCLC patients than HCs (p < 0.001). Besides, elevated CDC42 expression was correlated with the occurrence of lymph node (LYN) metastasis (p = 0.003) and advanced TNM stage (p = 0.007), but not related to other tumor features, demographic characteristics, comorbidities, nor neoadjuvant/adjuvant chemotherapy (all p > 0.05). Additionally, elevated CDC42 expression was correlated with unfavorable accumulating disease-free survival (DFS) (p < 0.001) and overall survival (OS) (p = 0.025). More importantly, multivariate Cox's proportional hazard regression analysis revealed that elevated CDC42 expression (hazard ratio (HR): 1.284, p < 0.001) and higher TNM stage (HR: 1.428, p = 0.003) were independently associated with shorter DFS, meanwhile elevated CDC42 expression (HR: 1.193, p = 0.035), higher pathological grade (HR: 1.558, p = 0.003), higher TNM stage (HR: 1.703, p = 0.001) and higher Eastern Cooperative Oncology Group performance status (ECOG PS) score (HR: 1.538, p = 0.038) were independently correlated with unsatisfying OS. CONCLUSION Circulating CDC42 is highly expressed with its overexpression linked with LYN metastasis, poor DFS, and OS in NSCLC patients.

Abstract
Drug resistance is a critical factor responsible for the recurrence of non-small cell lung cancer (NSCLC). Previous studies suggest that curcumin acts as a chemosensitizer and radiosensitizer in human malignancies, but the underlying mechanism remains elusive. In the present study, we explored how curcumin regulates the expression of miR-142-5p and sensitizes NSCLC cells to crizotinib. We found that miR-142-5p is significantly downregulated in NSCLC tissue samples and cell lines. Curcumin could increase crizotinib cytotoxicity by epigenetically restoring the expression of miR-142-5p. Furthermore, curcumin treatment suppressed the expression of DNA methylation-related enzymes, including DNMT1, DNMT3A, and DNMT3B, in NSCLC cells. In addition, the upregulation of miR-142-5p expression increased crizotinib cytotoxicity and induced apoptosis in tumor cells in a similar manner to that of curcumin. Strikingly, miR-142-5p overexpression suppressed crizotinib-induced autophagy in A549 and H460 cells. Mechanistically, miR-142-5p inhibited autophagy in lung cancer cells by targeting Ulk1. Overexpression of Ulk1 abrogated the miR-142-5p-induced elevation of crizotinib cytotoxicity in A549 and H460 cells. Collectively, our findings demonstrate that curcumin sensitizes NSCLC cells to crizotinib by inactivating autophagy through the regulation of miR-142-5p and its target Ulk1.
