Filter by:To collect data on diagnostic yield of thin and ultrathin bronchoscopes with radial probe endobronchial ultrasound (radial EBUS) and transbronchial needle aspiration (TBNA) during routine standard of care bronchoscopy for peripheral pulmonary lesions.
The primary objectives of this study are to assess the sensitivity and specificity of SGM-101 in detecting non-small cell lung carcinomas during surgery when excited by an near-infrared light source utilizing intraoperative imaging.
Lung cancer is currently one of the most common malignant tumors in the world. In recent years, with the popularity of high-resolution CT, more and more early-stage lung cancers have been found. Anatomic pneumonectomy is gradually popular because it can completely remove lung nodules and preserve lung function to the greatest extent. During the surgery, the precise and rapid determination of intersegmental border is one of the key technologies. Improved inflation-deflation method is currently the most widely used method in clinical practice. Previous studies demonstrated that increasing the concentration of nitrous oxide in mixtures of N2O/O2 will lead to a faster rate of collapse. The rapid diffusion properties of N2O would be expected to speed lung collapse and so facilitate surgery. This study was designed to explore three types of inspired gas mixture used during two-lung anesthesia had an effect on the intersegmental border appearance time during pneumonectomy and its feasibility and safety: 75% N2O (O2: N2O = 1: 3), 50% N2O (O2: N2O = 1: 1), 100% oxygen.
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.
As the detection of small pulmonary nodules continuously grows, the intraoperative localization of small pulmonary nodules is in great demand. The intraoperative localization nowadays is usually done under local anesthesia before surgery. There is a certain rate of failure and complication. The result of our early animal experiments show that the pulmonary surgery marker system can deliver the intraoperative localization safely and precisely under anesthesia, and the average distance between the localization and the simulated lesion is less than 5mm during surgery. Therefore, the safety and feasibility of the system require further evaluation in patients
To assess the variability of semi-automated volume measurements of pulmonary nodules on same-day repeated scans of equal radiation dose from two different CT scanners: One high-end CT scanner with standard spatial resolution (CT1) and one UHRCT scanner (CT2), in patients with known or suspected pulmonary metastases.
The purpose of this study is to actively monitor patients with multiple pulmonary Ground-glass Nodules (GGNs), in order to provide evidence for multiple GGNs treatment.
This study through the detection of EGFR、ALK、ROS1、KRAS、HER2、BARF、NTRG1 seven ctDNA and exosome RNA in the blood and alveolar lavage of lung nodules patients and heavy smoking healthy population. If the results of ctDNA test is positive, the target nodule is malignant; if the reaults of ctDNA teste is negatie but exocome RNA is positive, the target nodule is also malignant. If the results of both tests are negtive, the target nodule is recognized as benign. The purpose is study the sensitivity, specificity and diagnostic accuracy of ctDNA and exosome combined detection in the identification of benign and malignant pulmonary nodules. Besides, the diagnostic efficacy of different specimens including blood and alveolar lavage in the identification of benign and malignant pulmonary nodules is also studied.
This study is designed to evaluate clinical safety and diagnostic accuracy of the robotic-assisted bronchoscopy with biopsy performed with the Monarch™ Endoscopy Platform in a broad range of patients with pulmonary lesions.
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.
