Filter by:Multi-center randomized controlled study designed to compare the diagnostic yield of ION™ Endoluminal System with electromagnetic navigation bronchoscopy in patients undergoing transbronchial sampling procedure of peripheral pulmonary nodules.
This is a pragmatic clinical trial that will study the effect of a radiomics-based computer-aided diagnosis (CAD) tool on clinicians' management of pulmonary nodules (PNs) compared to usual care. Adults aged 35-89 years with 8-30mm PNs evaluated at Penn Medicine PN clinics will undergo 1:1 randomization to one of two groups, defined by the PN malignancy risk stratification strategy used by evaluating clinicians: 1) usual care or 2) usual care + use of a radiomics-based CAD tool.
Since the beginning of lung screening program in the different countries around the world by chest CT scan, numerous lung nodules and masses of unknown etiology are diagnosed. Usually, the pathological diagnosis is obtained by bronchoscopy. However, peripheral bronchi cannot be seen after the fifth bronchial division as the diameter of the broncoscope is greated than the diameter of the bronchi. Therefore, the Iriscope was developed. It consists in a thin catheter with a mini-camera at its distal extremity. The aime of this study is to evaluate the diagnostic yield of bronchoscopy guided by Iriscope in the setting of peripheral lung nodules and masses supect of malignancy, to compare the Iriscope to endobronchial radial ultrasonography (which is a validated technique to guide bronchoscopy in the setting of peripheral lung nodules and masses) and to evaluate the added value on the diagnostic yield by combining these 2 techniques.
Lung cancer is the first cancer in China in terms of morbidity and mortality. The problem of early diagnosis/treatment has always been concerned. The popularization of chest CT (electronic computed tomography) screening makes it possible to detect lung cancer early. However, the diagnosis still needs pathological evidence. It is an ideal choice to obtain pathological evidence through bronchoscope and other minimally invasive means before surgical resection. However, the positive rate of tracheoscopy is still unsatisfactory, which is related to the difficulty of traditional pathological detection in detecting small specimens obtained by tracheoscopy. Liquid biopsy technology based on methylation detection has been used in early cancer screening, but its advantages have not been fully exploited due to the low content of ctDNA (circulating tumor DNA) in the current detection samples. Therefore, through prospective clinical research, the investigators plan to combine the methylation detection technology based on "Whole genome methylation sequencing(GM-seq)" with tracheoscopy, compare the traditional pathological methods with methylation detection on the bronchoscopic samples of lung nodule subjects suspected of early lung cancer, and take the postoperative pathology as the gold standard for judging benign and malignant, to confirm the feasibility and advantages of the new technology.
This study is a multi-centre prospective observational cohort study recruiting patients with 5-30mm solid and part-solid pulmonary nodules that have been detected on CT chest scans performed as part of routine practice. The aim is to determine whether physician decision making with the AI-based LCP tool, generates clinical and health-economic benefits over the current standard of care of these patients.
This study evaluates the viability and accuracy of preoperative mixed reality technique combined with three-dimensional printing navigational template guided localizing pulmonary small nodules.
This study will collect retrospective CT scan images and clinical data from participants with incidental lung nodules seen in hospitals across London. The investigators will research whether machine learning can be used to predict which participants will develop lung cancer, to improve early diagnosis.
Fluorescence-navigated thoracoscopic imaging with indocyanine green (ICG) is a novel technique for detection of small pulmonary nodules other than traditional radiography or intraoperative palpation. As a non-targeted fluorescent contrast agent, ICG accumulates in tumors by the enhanced permeability and retention effect (EPR), making the lesions fluoresce under fluorescent imaging. However, the optimal dosage and injection time of ICG are still under exploration. Hence, we perform this study in humans made up of four groups to determine the optimal time and dose.
The researchers are aimed to investigate the early diagnosis of pulmonary nodule based on DNA, RNA, protein, metabolites through analyzing the serum, plasma, urine, faeces, peripheral blood mononuclear cell (PBMC), exhaled breath condensate and clinical characteristics.
- The purpose of the study is the identification of the efficacy of MDA Test to Differentiate of Benign and Malignant Pulmonary Nodules. - In this study, the investigators are going to validate the efficacy of the MDA test for diagnosing early lung cancer by comparing results of the pre-surgery MDA test with the post-surgery pathology.
