Impact of Pulmonary Ligament Resection in Upper Lobectomies: A Multicenter Matched Cohort Study.

: Division of the pulmonary ligament is standard in lower lobectomies, but its application in upper lobectomies remains controversial due to potential complications like atelectasis and bronchial kinking. This retrospective matched cohort study aimed to evaluate the efficacy and safety of ligament resection in upper lobectomies for oncological purposes. : From January 2015 to December 2020, 988 patients who underwent minimally invasive upper lobectomies across multiple centers were identified.

Specific Deletions of Chromosomes 3p, 5q, 13q, and 21q among Patients with G2 Grade of Non-Small Cell Lung Cancer.

Non-small cell lung cancer (NSCLC) leads as a primary cause of cancer-related premature mortality in Western populations. This study leverages cutting-edge gene-expression-profiling technologies to perform an in-depth molecular characterization of NSCLC specimens, with the objective of uncovering tumor-specific genomic alterations. By employing DNA microarray analysis, our research aims to refine the classification of NSCLC for early detection, guide molecular-targeted treatment approaches, enhance prognostication, and broaden the scientific understanding of the disease's biology.

The relation of body adiposity to the outcomes of thoracoscopic lobectomy for lung cancer - a single-center cohort study.

Introduction: The outcomes of lung cancer surgery depend on the patients' nutritional status. Body fat percentage (BF%) is one of the indicators of body composition and nutritional status. Direct measurement of BF% is complicated, requires significant resources and is rarely performed.

Background: High-energy devices allow better vessel sealing compared with monopolar electrocautery and could improve the outcomes of surgical operations. The objective of the study was to compare tissue dissection by the LigaSure™ device with that by monopolar electrocoagulation for thoracoscopic lobectomy and lymphadenectomy.

Methods: This pragmatic, parallel group, prospective randomized controlled trial was funded by the Medtronic External Research Program (ISR-2016-10,756) and registered at www.

A Multicenter Retrospective Cohort Study on Superior Vena Cava Resection in Non-Small-Cell Lung Cancer Surgery.

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.

The technique of stump closure has no impact on post-pneumonectomy bronchopleural fistula in the non-small cell lung cancer-a cross-sectional study.

Background: Pneumonectomy is a high-risk radical resection procedure, with bronchopleural fistula (BPF) being its most challenging and severe complication. This study aimed to assess the surgical risk factors and the impact of the bronchial stump closure technique on the incidence of the BPF.

Methods: This is a single-center, cross-sectional study of the medical records of 455 post-pneumonectomy patients operated due to non-small cell lung cancer (NSCLC) in 2006-2017.

Outcomes of lung cancer surgery in patients with COVID-19 history: a single center cohort study.

Objectives: Coronavirus disease 2019 (COVID-19) can irreversibly damage the lungs and could possibly increase the risk of surgical treatment of lung cancer. The study aimed to assess the relationship between preoperative COVID-19 and complications and early outcomes of lung cancer surgery.

Methods: This single-center cohort study included 444 patients who underwent lobectomy or segmentectomy for primary lung cancer from January 1, 2019 to December 31, 2021.

Surgical Management of Primary Spontaneous Pneumothorax Without Lung Bullae.

Introduction: Primary spontaneous pneumothorax (PSP) is a relatively common disease. Different studies have been published but lung resection, when no emphysema-like changes (ELC) are detected, is unclear. The aim of our study is to retrospectively investigate the role of lung resection of the apex of the lung in patients with no ELC.

Ninety-Day Mortality of Thoracoscopic vs Open Lobectomy: A Large Multicenter Cohort Study.

Background: Studies have demonstrated a lower incidence of complications after video-assisted thoracoscopic surgery (VATS) lobectomy compared with thoracotomy, but the data on in-hospital and 90-day mortality are inconclusive. This study analyzed whether surgical approach, VATS or thoracotomy, was related to early mortality of lobectomy in lung cancer and determined the differences between in-hospital and 90-day mortality.

Methods: Data of all patients with non-small cell lung cancer who underwent lobectomy between January 1, 2007, and July 30, 2018, were retrieved from Polish National Lung Cancer Registry.

Background: The surgical treatment of advanced non-small-cell-lung-cancer (NSCLC) invading mediastinal organs and great vessels is still controversial. The aim of this multicentre study is to analyse oncological outcomes, surgical outcomes and prognostic factors of patients with NSCLC involving heart and great vessels.

Methods: 362 patients treated surgically for locally advanced T4-NCSLC between 1990 and 2020 were retrospectively reviewed.

Long term results of surgery for NSCLC and aortic invasion. A multicenter retrospective cohort study.

Background: Aortic invasion from non-small cell lung cancers (NSCLC) is a relative contraindication to surgery for oncological and technical reasons.

Autologous Blood Patch Pleurodesis: A Large Retrospective Multicenter Cohort Study.

Background: Prolonged air leaks (PAL) complicate 10% to 15% of lung resections, delaying chest tube removal and prolonging length of hospital stay. No consensus exists for managing this common complication, despite favorable results for autologous blood patch pleurodesis (ABPP) in the literature. The aim of this study was to evaluate the effectiveness and safety of ABPP.
