Active clinical trials for "Multiple Pulmonary Nodules"

The study aims to determine if there are defining EBUS and confocal endoscopy features as well as exhaled alveolar gas VOC that can discriminate malignant pulmonary nodules or masses from benign etiology, thereby obviating unnecessary thoracotomy. Directly sampled alveolar gas VOC from patients with lung cancer will be compared against exhaled breath VOC for signature compounds that may complement CT in screening the population at risk.

This study is intended to determine the positive predictive value (PPV) and negative predictive value (NPV) of the multiprotein classifier based on the observed study prevalence of Non-Small Cell Lung Cancer (NSCLC) in the study participants.

The primary objective of this study is to obtain de-identified, clinically characterized, whole blood specimens for use in assessing new biomarkers for the detection of neoplasms of the lung. Subjects will be men and women, 35 years of age and older, with a CT confirmed nodule measuring 6-30 mm.

To investigate the diagnostic value of ultralow-dose computed tomography in the detection of pulmonary nodules and lung parenchym alterations (e.g. emphysema) compared to standard-dose-CT.

The ex-vivo lung will be evaluated by XLTF-UC180 for localization of the tumor. The ultrasound probe will be put on the lung surface in several different directions to obtain the cross section with maximum diameter. The ultrasound image with size measurement of the tumor will be recorded using an ultrasound scanner (EU-Y0008, OLYMPUS MEDICALSYSTEMS CORP., Tokyo, Japan). Next, the bronchial stump of the specimen will be opened and a small sized endotracheal tube will be inserted to inflate and deflate the lung. After inflation of the lung, the tumor will be evaluated by XLTF-UC180 to see the difference in ultrasound images between deflated and inflated lung. After ultrasound evaluation, the specimen will be delivered directly to the pathology laboratory and the actual tumor size and histological diagnosis will be determined. In addition, we will evaluate the differences between US image and pathological morphology using HE slides of lung tumor. We will work together with the surgical team to confirm sign off of specimens.

The main purposes of this study are to assess the performance characteristics of transbronchial needle aspiration (TBNA) in the diagnosis of peripheral pulmonary lesions, and to identify the predictor variables of a positive aspirate.

The study is designed as a multi-center prospective trial with two arms, ENB-EBUS-GS group and EBUS-GS group, and aimed to evaluate the diagnostic yield and operation time between the two groups.

A single-centre, industry sponsored, pilot study to assess the feasibility of Single Exposure Dual Energy Subtraction with a Multi-Energy digital radiography detector as an imaging platform for lung lesion detection.

The investigators aim to investigate the utility of radiomics to differentiate malignant nodules from benign nodules and invasive adenocarcinoma from non-invasive adenocarcinoma.

One of the main challenges of thoracic oncology lies in earlier diagnosis of lung cancer to improve survival rate, wich is about 15% at 5 years. This poor prognosis is often linked to late diagnosis. Efforts are being made worldwide to offer testing in patients at risk or earlier diagnosis of lung cancer in order to offer the patient curative treatments. Indeed, supported at the stage of nodule (less than 3 cm lesion), lung cancer is curable by surgery in 80% of patients. Nevertheless, there are many differential diagnoses and access to these lesions is often difficult and risky. In this context, the management of pulmonary nodules, which can be either benign lesions or beginners cancers, is a real challenge for pulmonologists and thoracic oncologists every day: it is important not to disregard a potentially operable nodule and avoiding offer patients invasive procedures for benign nodules. Indeed, many procedures (endoscopy, puncture under scanner, thoracotomy) are made to determine if suspicious nodules are benign or not. In the large National Lung Screening Trial, 28% of the procedures were associated with complications (including 11% classified severe and 16 deaths). It is therefore essential to develop non-invasive tools to refine treatment decisions.
