Background: The ubiquitously expressed transmembrane protein, Herpesvirus Entry Mediator (HVEM), functions as a molecular switch, capable of both activating and inhibiting the immune response depending on its interacting ligands. HVEM-Fc is a novel recombinant fusion protein with the potential to eradicate tumor cells.

Methods: The anti-tumor efficacy of HVEM-Fc was evaluated in C57BL/6 mice-bearing lung cancer models: a syngeneic model and an orthotopic model of mouse lung cancer.

Herpes virus entry mediator (HVEM) is a novel costimulatory molecule which mediates stimulatory or inhibitory signals in immune responses which makes it an attractive target in cancer therapeutics. However, the role of tumor cell intrinsic HVEM on tumor biology remains largely unknown. In this study, We demonstrated that CK+HVEM+ tumor correlates with better survival using Multiplex immuno histochemistry (mIHC) in Human Lung Adenocarcinoma Tissue microarray.

This study extends the Job Demands-Resources (JD-R) framework by proposing JD-R 3.0, which explores the dynamic and nonlinear relationships among Work Connectivity Behavior After-Hours (WCBA), Perceived Organizational Support (POS), and employee outcomes, with a specific focus on psychological contract violation (PCV) and psychological distress. Data were collected from 625 employees in a large financial organization in China across two waves, and polynomial regression and response surface analysis were used for hypothesis testing.

Reactive oxygen species (ROS) are metabolic by-products of cells, and abnormal changes in their levels are often associated with tumor development. Our aim was to determine the role of collagen and calcium binding EGF domain 1 (CCBE1) in oxidative stress and tumorigenesis in non-small cell lung cancer cells (NSCLC). We investigated the tumorigenic potential of CCBE1 in NSCLC using in vitro and in vivo models of CCBE1 overexpression and knockdown.

Objectives: Anastomotic leak (AL) is one of the most serious complications after oesophageal cancer surgery. A high cervical anastomosis using a narrow gastric tube based on optimized procedures has the potential to reduce the AL after a McKeown oesophagectomy.

Methods: A narrow gastric tube was defined as 2-2.

Article Synopsis
  • - The study investigates the effectiveness of perioperative immunotherapy (using tislelizumab) in combination with chemotherapy for patients with locally advanced resectable esophageal squamous cell carcinoma (ESCC), building on previous phase II clinical trials that showed promising results.
  • - A total of 73 patients were treated with neoadjuvant immunotherapy and chemotherapy, with some receiving further adjuvant treatment based on their response after surgery; the main focus is on the 2-year disease-free survival (DFS) rates in patients who did not achieve a complete response.
  • - This trial, approved by the Ethics Committee of Shanghai Chest Hospital, is the first of its kind to explore the safety and efficacy of this treatment approach, hypoth

Genome-wide association studies have identified numerous single-nucleotide polymorphisms (SNPs) associated with lung cancer; however, the functions of histone deacetylase 2 (HDAC2) rs13213007 and HDAC2 in nonsmall cell lung cancer (NSCLC) remain unclear. Here we identified HDAC2 rs13213007 as a risk SNP and showed that HDAC2 was upregulated in both peripheral blood mononuclear cells (PBMCs) and NSCLC tissues with the rs13213007 A/A genotype compared with those with the rs13213007 G/G or G/A genotype. Patient clinical data indicated strong associations between rs13213007 genotype and N classification.

Background: Surgery for non-small-cell lung cancers (NSCLCs) invading the superior vena cava (SVC) is rarely performed due to surgical complexities and reported poor prognoses. Different methods have been described to reconstruct the SVC, such as direct suture, patch use or prosthesis, according to its circumferential involvement. The aim of our study was to analyze the short- and long-term results of different types of SVC resection and reconstruction for T4 NSCLCs.

Article Synopsis
  • Immune cell infiltration (ICI) patterns are crucial for understanding the progression of lung squamous cell carcinoma (LUSC), but their specifics have not been fully explored.
  • Researchers used various datasets and analytical methods, including TCGA and different algorithms, to quantify and categorize ICI patterns in LUSC samples, leading to the identification of four distinct immune infiltration patterns with different prognoses.
  • The study found that high ICI scores indicate immunosuppression and poor outcomes, while low ICI scores are associated with better immune responses and potential therapeutic benefits, establishing a link between ICI patterns and immunotherapy effectiveness.

Objective: Total mesoesophageal excision (TME) is a promising procedure. Prone position thoracoscopic-assisted TME might be a good choice, even without robust evidence yet. Therefore, it is necessary to explore the safety and efficacy of this procedure.

Background: Recently, circulating tumor-cell-associated white blood cell (CTC-WBC) clusters have been reported to have prognostic value in some cancers. The prognostic role of CTC-WBC clusters in lung cancer has not yet been elucidated. Very little information is available about the biological characteristics of CTC-WBC clusters.

Background: Accurate preoperative prediction of the invasiveness of lung nodules on computed tomography (CT) can avoid unnecessary invasive procedures and costs for low-risk patients. While previous studies approached this task using cross-sectional data, this study aimed to utilize the commonly available longitudinal data of lung nodules through sequential modelling based on long short-term memory (LSTM) networks.

Methods: We retrospectively included 171 patients with lung nodules that were followed-up at least once and pathologically diagnosed with adenocarcinoma for model development.

Background: Whether changes of lung nodules on computed tomography could bring us helpful information related to their pathological outcomes remained unclear.

Materials And Methods: This retrospective study was carried out among 1,185 cases of lung nodules in Shanghai Chest Hospital from January 2015 to April 2017, which did not shrink or disappear after preoperative follow-up over three months. Their imaging features, changes, and clinical characteristics were collected.

Background: Patients with early-stage lung cancer are sometimes medically inoperable, and for patients with multiple primary lung cancers, surgical resection alone sometimes proves to be impractical. Local treatments like microwave ablation (MWA) are investigational alternatives for these patients. Most reported MWA procedures for lung cancers are performed percutaneously under CT guidance.

N-Methyladenosine (mA) RNA modification brings a new dawn for RNA modification researches in recent years. This posttranscriptional RNA modification is dynamic and reversible, and is regulated by methylases ("writers"), demethylases ("erasers"), and proteins that preferentially recognize mA modifications ("readers"). The change of RNA mA modification regulates RNA metabolism in eucaryon, including translation, splicing, exporting, decay, and processing.

Background: T4 tumours comprise a heterogeneous group of locally invasive non-small cell lung cancers (NSCLC). Intrapericardial and extrapericardial involvement of the pulmonary artery (PA) may have a different prognosis. We compared the short and long-term surgery outcomes for NSCLC of the PA with intrapericardial or extrapericardial involvement.

Background: We aim to establish neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) related nomograms based on the clinical data and peripheral blood markers to predict the survivals of patients with limited-stage small-cell lung cancer (LS-SCLC).

Methods: A total of 299 LS-SCLC patients after surgery were enrolled in this study. Univariate and multivariate analyses were conducted to select independent prognostic factors to develop the nomograms and then subjected to bootstrap internal validation.
