Prevalence and management of pulmonary nodules: a systematic review and meta-analysis.

Background: Pulmonary nodules are small, focal lesions often identified via computed tomography (CT) scans. Although the majority are benign, a small percentage of them may be malignant or potentially become malignant, underscoring the importance of early detection and effective management. This study systematically reviews the epidemiology, risk factors, and management strategies for pulmonary nodules, comparing findings across Chinese and non-Chinese populations to better inform the actuarial calculations for predicting the demand of medical services for patients with pulmonary nodules.

Endobronchial Ultrasound/Transbronchial Needle Aspiration-Biopsy for Systematic Mediastinal lymph Node Staging of Non-Small Cell Lung Cancer in Patients Eligible for Surgery: A Prospective Multicenter Study.

Background: The treatment of lung cancer depends on histological and/or cytological evaluation of the mediastinal lymph nodes. Endobronchial ultrasound/transbronchial needle aspiration-biopsy (EBUS/TBNA-TBNB) is the only minimally invasive technique for a diagnostic exploration of the mediastinum. The aim of this study is to analyze the reliability of EBUS in the preoperative staging of non-small cell lung cancer (NSCLC).

Methods: level in tissues and cells was tested by immunohistochemistry, western blot, and quantitative real-time polymerase chain reaction (qRT-PCR). The impacts of on cell viability, proliferation, apoptosis, invasion, and migration were determined by Cell Counting Kit-8 (CCK-8), colony formation assay, flow cytometry, transwell assay, and wound healing assay, respectively.

Chest wall reconstruction in benign and malignant tumors with non-rigid materials: An overview.

Several materials and techniques have been described for the procedure of chest wall reconstruction: the choice of using a technique or a material over another relies mainly on the surgeon's experience as well as thoracic defect localization and dimension, local availability of materials, and costs. From a technical point of view, autologous and alloplastic reconstruction are available, and, in both cases, rigid and non-rigid prostheses are found. Each material has its peculiarities, with advantages and disadvantages; thus, it is mandatory to be confident when planning the intervention to foresee possible complications and minimize them.

Proteomic analysis of plasma exosomes in patients with non-small cell lung cancer.

Background: Currently, the prognosis of patients with non-small cell lung cancer (NSCLC) remains unsatisfactory. This current study evaluated the relationship between histology of NSCLC and protein expression of exosomes in the plasma from NSCLC patients, and furthermore investigate the impact of the exosome profile on the tumor, node, metastasis (TNM) classification.

Methods: Plasma samples were collected from 26 NSCLC patients before surgery.

Chest wall reconstruction with implantable cross-linked porcine dermal collagen matrix: Evaluation of clinical outcomes.

Objectives: The aim of the study is to evaluate clinical applications, safety, and effectiveness of a porcine-derived acellular cross-linked dermal matrix biological mesh in chest wall reconstruction.

Methods: We retrospectively analyzed a prospective multicenter database of chest wall reconstructions using a biological mesh in adult patients undergoing operation between October 2013 and December 2020. We evaluated preoperative data, type of resection and reconstruction, hospitalization, 30-day morbidity and mortality, and overall survival.

Osimertinib as induction therapy for oligometastatic non-small cell lung cancer with EGFR mutation: a case report.

Background: The role of surgery in combined modality therapy for selected stage IV oligometastatic (OM) non-small cell lung cancer (NSCLC) is still controversial. Tyrosine kinase inhibitors (TKIs) targeting epidermal growth factor receptor (EGFR) significantly improved the survival in adjuvant therapy in metastatic NSCLC but has rare evidence in inductive setting. This is the first case report about uniportal video-assisted thoracic surgery after induction therapy of TKI for OM-NSCLC.

The Overweight Paradox: Impact of Body Mass Index on Patients Undergoing VATS Lobectomy or Segmentectomy.

The aim of this study was to assess the impact of BMI on perioperative outcomes in patients undergoing VATS lobectomy or segmentectomy. Data from 5088 patients undergoing VATS lobectomy or segmentectomy, included in the VATS Group Italian Registry, were collected. BMI (kg/m) was categorized according to the WHO classes: underweight, normal, overweight, obese.

Techniques and outcomes of bronchoplastic and sleeve resection: an 8-year single-center experience.

Background: Bronchial reconstruction is one of the most challenging procedures for thoracic surgeons. This study aimed to report the surgical techniques and clinical outcomes of bronchoplastic and sleeve resection for central lung cancer and summarize our center's experience of this challenging procedure over the past 8 years.

Methods: Between January 2013 and April 2021, 54 patients underwent a sleeve resection or a lobectomy with bronchoplasty, including 11 patients who received video-assisted thoracoscopic surgery (VATS) bronchial sleeve resection (4 via the uniportal approach and 7 via the biportal approach).

NSCLC Immunotherapy and Related Rare Toxicities: A Monocentric Real-Life Experience.

Background: In the last years immunotherapy has revolutionized the treatment of non-small cell lung cancer (NSCLC) not supported by a driver mutation. Immunotherapy related adverse events (irAEs) have a unique toxicity profiles distinct from the toxicities of classical chemotherapy treatment relating to their mechanism of action. We analyzed some serious and uncommon life-threatening irAEs, needing a change in the therapeutic strategy.

Is It Possible to Establish a Reliable Correlation between Maximum Standardized Uptake Value of 18-Fluorine Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography and Histological Types of Non-Small Cell Lung Cancer? Analysis of the Italian VATS Group Database.

Background: Although positron emission tomography/computed tomography, often integrated with 2-deoxy-2-[fluorine-18] fluorine-D-glucose (18F-FDG-PET/CT), is fundamental in the assessment of lung cancer, the relationship between metabolic avidity of different histotypes and maximum standardized uptake value (SUVmax) has not yet been thoroughly investigated. The aim of the study is to establish a reliable correlation between Suvmax and histology in non-small cell lung cancer (NSCLC), in order to facilitate patient management.

Methods: We retrospectively assessed the data about lung cancer patients entered in the Italian Registry of VATS Group from January 2014 to October 2019, after establishing the eligibility criteria of the study.

Case Report: A New Tool for Anterior Chest Wall Reconstruction After Sternal Resection for Primary Or Secondary Tumors.

Sternal resection and anterior chest wall reconstruction techniques for malignant processes are not always standardized. We report an innovative method of sternal osteosynthesis in two patients, 65-year-old and 41-year-old women, with Ewing's sarcoma, and infiltrating thymoma, respectively. The first case manifested itself as a voluminous palpable mass while the second case was characterized for a paramediastinal mass widely extended to the anterior chest wall.

Surgery in COVID-19 disease complicated by APF represents the last life-saving treatment option. The choice of the therapeutic period to indicate this approach is fundamental. In fact, the clinical stability of patient is necessary in order to allow single-lung ventilation and to minimize postoperative sequelae.

Targeting histone deacetylase enhances the therapeutic effect of Erastin-induced ferroptosis in -activating mutant lung adenocarcinoma.

Background: Intrinsic or acquired resistance to epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) is common, thus strategies for the management of EGFR-TKIs resistance are urgently required. Ferroptosis is a recently discovered form of cell death that has been implicated in tumorigenesis and resistance treatment. Accumulating evidence suggests that ferroptosis can be therapeutically exploited for the treatment of solid tumors; however, whether ferroptosis can be targeted to treat mutant lung cancer and/or overcome the resistance to EGFR-TKIs is still unknown.
