Awake video-assisted surgical lung biopsy for the diagnosis of interstitial lung disease.

In patients with suspected interstitial lung disease, diagnostic confirmation can be achieved through an awake video-assisted surgical lung biopsy. This procedure enables the collection of a substantial amount of parenchymal tissue for diagnostic purposes while minimizing perioperative complications associated with mechanical ventilation with the patient under general anaesthesia, given the impaired lung function due to the underlying condition.

Peripheral Circulating Blood Cells Deviation Based on Tumor Inflammatory Microenvironment Activity in Resected Upstaged Lung Adenocarcinomas.

: The tumour inflammatory microenvironment (TIME) reflects a selective activation of the central immune system (IS), particularly T-cells expansion, which leads to immune cells migrating to the target, such as lung cancer, via the bloodstream and lymphatic vessels. In this study, the aim is to investigate whether the distribution of peripheral blood cells varies based on the immune status of patients with lung adenocarcinoma. : This is a single-center retrospective study conducted in the Thoracic Surgery Unit of the University of Padua (Italy) between 1 January 2016 and 1 April 2024.

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.

Meeting the challenge of varietal and geographical authentication of hazelnuts through lipid metabolite fingerprinting.

Hazelnuts are high-quality products with significant economic importance in many European countries. Their market price depends on their qualitative characteristics, which are driven by cultivar and geographical origin, making hazelnuts susceptible to fraud. This study systematically compared two lipidomic fingerprinting strategies for the simultaneous authentication of hazelnut cultivar and provenance, based on the analysis of the unsaponifiable fraction (UF) and triacylglycerol (TAG) profiles by gas chromatography-mass spectrometry coupled with chemometrics.

A new vessel filled and heart-beating human corpse model for VATS lobectomy training.

Background: Nowadays, video-assisted thoracic surgery (VATS) lobectomy represents the treatment of choice for early-stage lung cancer. Over the years, different methods for VATS training have evolved. The aim of this study is to present an innovative beating-heart filled-vessel cadaveric model to simulate VATS lobectomies.

Thoracic Ultrasound as an Alternative to Chest X-ray in Thoracic Surgery Patients: A Single-Center Experience.

: Chest X-ray (CXR) is currently the most used investigation for clinical follow-up after major noncardiac thoracic surgery. This study explores the use of lung ultrasound (LUS) as an alternative to CXR in the postoperative management of patients who undergo major thoracic procedures. : The patients in our cohort were monitored with both a CXR and a lung ultrasonography after surgery and the day after chest drain removal.

Tumor inflammatory microenvironment contribution to survival in resected upstaged adenocarcinomas.

Introduction: Tumor Inflammatory microenvironment (TIME) encompasses several immune pathways modulating cancer development and escape that are not entirely uncoded. The results achieved with immunotherapy elicited the scientific debate on TIME also in non-small cell lung cancer (NSCLC). We aimed to investigate whether TIME (in terms of PD-L1 expression and/or Tumor Infiltrating Lymphocytes - TILs) played a separate role in terms of survival (OS) in resected upstaged lung adenocarcinomas (ADCs), excluding other perioperative variables as confounders.

Significance of Spread Through Air Spaces and Vascular Invasion in Early-stage Adenocarcinoma Survival: A Comprehensive Clinicopathologic Study of 427 Patients for Precision Management.

Spread through air spaces (STAS) is a novel invasive pattern of lung cancer associated with poor prognosis in non-small cell cancer (NSCLC). We aimed to investigate the incidence of STAS in a surgical series of adenocarcinomas (ADCs) resected in our thoracic surgery unit and to identify the association of STAS with other clinicopathological characteristics. We retrospectively enrolled patients with stage cT1a-cT2b who underwent resection between 2016 and 2022.

Three-Dimensional Imaging-Guided Lung Anatomic Segmentectomy: A Single-Center Preliminary Experiment.

: VATS segmentectomy has been proven to be effective in the treatment of stage I NSCLC, but its technical complexity remains one of the most challenging aspects for thoracic surgeons. Furthermore, 3D-CT reconstruction images can help in planning and performing surgical procedures. In this paper, we present our personal experience of 11 VATS anatomical resections performed after accurate pre-operative planning with 3D reconstructions.

Impact of a standardized protocol for chest tube management after VATS pulmonary resections on post-operative outcomes and complications.

Chest tube management represents a major issue after lung surgery as no protocol is widely accepted and tube management is generally based on local or personal habits. Aim of this study is to evaluate the impact of a standardized protocol for chest tube management after pulmonary resections on the post-operative outcomes. We performed a single center retrospective analysis of all adult patients undergoing thoracoscopic pulmonary resection from January 2020 to December 2021.

Microscopical Variables and Tumor Inflammatory Microenvironment Do Not Modify Survival or Recurrence in Stage I-IIA Lung Adenocarcinomas.

Microscopical predictors and Tumor Immune Microenvironment (TIME) have been studied less in early-stage NSCLC due to the curative intent of resection and the satisfactory survival rate achievable. Despite this, the emerging literature enforces the role of the immune system and microscopical predictors as prognostic variables in NSCLC and in adenocarcinomas (ADCs) as well. Here, we investigated whether cancer-related microscopical variables and TIME influence survival and recurrence in I-IIA ADCs.

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.

Comparison of operative and postoperative characteristics and outcomes between thoracoscopic segmentectomy and lobectomy for non-small-cell lung cancer: a propensity score matching study from the Italian VATS Group Registry.

Objectives: Only few studies compared the surgical morbidity and mortality of thoracoscopic segmentectomy versus lobectomy for non-small-cell lung cancer, in particular, by relating the segmental resections with the corresponding anatomical lobes.

Methods: We enrolled a total of 7487 patients who underwent VATS lobectomy (7269) or segmentectomy (218) from January 2014 to July 2019. A propensity score matching approach was used to account for potential confounding factors between the 2 groups.

Short- and Long-Term Impact of Smoking Donors in Lung Transplantation: Clinical and Pathological Analysis.

Background: The use of smoking donors (SD) is one strategy to increase the organ pool for lung transplantation (LT), but the benefit-to-risk ratio has not been demonstrated. This study aimed to evaluate the impact of SD history on recipient outcomes and graft alterations.

Methods: LTs in 293 patients were retrospectively reviewed and divided into non-SD ( = 225, group I), SD < 20 pack-years ( = 45, group II), and SD ≥ 20 pack-years ( = 23, group III) groups.

Video-assisted thoracoscopic lobectomy after neoadjuvant chemotherapy for non-small cell lung cancer: a multicenter propensity-matched study.

Background: The role of video-assisted thoracoscopic surgery for the treatment of non-small-cell lung cancer after neoadjuvant chemotherapy remains controversial. The aim of this study is to demonstrate the reliability of video-assisted lobectomy compared to the open approach by evaluating perioperative and long-term outcomes.

Methods: In this retrospective, multicentric study from January 2010 to December 2018, we included all patients with non-small-cell lung cancer who underwent lobectomy through the video-assisted or open approach after neoadjuvant chemotherapy.

Lobectomy With Artery Reconstruction and Pneumonectomy for Non-Small Cell Lung Cancer: A Propensity Score Weighting Study.

Background: The treatment of non-small cell lung cancer is based, when suitable, on surgical resection. Pneumonectomy has been considered the standard surgical procedure for locally advanced lung cancers but it is associated with high mortality and morbidity rates. Reconstruction of the pulmonary artery, associated with parenchyma-sparing techniques, is meant to be an alternative to pneumonectomy.

Bronchus intermedius sleeve resection through a VATS approach.

In recent years, parenchymal sparing techniques for tumor resection have been developed in order to reduce the amount of lung parenchyma that must be removed in cases of centrally located tumors. These techniques maintain oncological radicality while reducing postoperative complications. At the same time, video-assisted thoracoscopic surgery (VATS) has been shown to offer comparable surgical and oncological outcomes to thoracotomy, even in complex cases that require tracheal and bronchial reconstructions.

Predictors of nodal upstaging in patients with cT1-3N0 non-small cell lung cancer (NSCLC): results from the Italian VATS Group Registry.

Purpose: Accurate staging of early non-small cell lung cancer is fundamental for selecting the best treatment. The aim of this study was to identify risk factors for nodal upstaging after video-assisted thoracoscopic lobectomy for clinical T1-3N0 tumors.

Methods: From 2014 to 2017, 3276 thoracoscopic lobectomies were recorded in the prospective database "Italian VATS Group".

Two-port intrapericardial left VATS pneumonectomy.

Pneumonectomy is a surgical treatment for locally advanced lung tumors that deeply infiltrate into the pulmonary hilum, and is a major thoracic procedure. An intrapericardial approach may be necessary in cases where it is  impossible to safely deal with the extrapericardial non-invaded sections of the pulmonary vessels. This article describes our technique for intrapericardial left video-assisted thoracoscopic pneumonectomy in a patient with hilar squamous cell carcinoma.

Predictors of unexpected nodal upstaging in patients with cT1-3N0 non-small cell lung cancer (NSCLC) submitted to thoracoscopic lobectomy.

Background: In the last decades, the use of video-assisted thoracoscopic surgery (VATS) lobectomy for the treatment of early stage non-small cell lung cancer is continuously growing. This is mainly due to the development of more advanced surgical devices, to the rising incidence of peripheral lung tumors and is also favored by the increased reliability of preoperative staging techniques. Despite this progress, postoperative unexpected nodal upstaging is still a relevant issue.

Terbium chelation, a specific fluorescent tagging of human transferrin. Optimization of conditions in view of its application to the HPLC analysis of carbohydrate-deficient transferrin (CDT).

Transferrin (Tf) is the major iron-transporting protein in the human body and, for this reason, has been extensively studied in biomedicine. This protein undergoes a complex glycosylation process leading to several glycoforms, some of which are important in the diagnosis of alcohol abuse and of congenital glycosylation defects under the collective name of carbohydrate-deficient transferrin (CDT). Exploiting the Tf ability to bind not only iron but also other ions, specific attention has been devoted to binding activity towards Tb, which was reported to greatly enhance its intrinsic fluorescence upon the interaction with Tf.
