Filter by:Endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration is a procedure used to obtain tissue samples (biopsies) of lymph nodes near the airways or of lung tumours growing in close proximity to the airways. Briefly, an endoscope with an ultrasound probe which is inserted through the mouth and into the airways. Once in the airways, the ultrasound allows for identification of the optimal biopsy site; a hollow biopsy needle is then inserted into the tissue under real-time ultrasound visualization and a sample is extracted. In the investigator's centre, the extracted sample is then immediately subjected to rapid on-site evaluation (ROSE). During the ROSE procedure, a cytotechnologist uses part of the sample to make a limited number direct smears which are then rapidly stained and evaluated under a microscope by the cytotechnologist. The cytotechnologist provides an assessment of the adequacy of the sample for diagnosis. The respirologist performing the EBUS then uses this information to: i) determine whether additional sampling is required, and ii) triage any additional samples for ancillary studies as needed. A final cytopathological diagnosis is established several days later, when all of the material from the procedure (including the material not evaluated at ROSE) is examined by a cytopathologist. There are different techniques which are utilized to perform the needle aspiration biopsy. Suction aspiration (where pressure suction is applied to the needle to draw out material) which is the standard at many centres around the world and capilliary suction (where a tiny wire is drawn back slowly to create more gentle suction force) which is utilized often at LHSC. The purpose of this study is to evaluate for differences in ROSE adequacy between these two methods.
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.
Image-guided percutaneous lung biopsy is an essential procedure in lung cancer management, where it is integral to confirming the diagnosis and determining tumour histology. An ideal percutaneous lung biopsy also needs to have a short procedure time with accurate needle placement to minimize the inherent risk of the procedure. Since the 1970s, conventional Multi-detector CT (MDCT) has been the modality of choice in percutaneous lung biopsy. Recent research has proposed CT fluoroscopy and cone-beam CT (CBCT) as alternative methods. Virtual guidance has been developed to improve target visibility and access for these complex cases. More specifically, it plans a potential computed 3D needle path before the procedure, using the CBCT images. This 3D path can be transposed onto real time fluoroscopic images to guide the biopsy, thus potentially improves patients' safety due to more accurate needle placement.
This study evaluates the use of ctDNA and CTCs in predicting disease activity and drug response in lung cancer patients and serves to complement existing methods to achieve a non-invasive and accurate means to guide treatment decisions.
This study aims to investigate the utility of circulating tumor DNA (ctDNA) methylation sequencing in the diagnosis of primary lung cancer.
The aim of this study is to reduce pathologic aspiration and pneumonia in the perioperative period by providing an oral care and oral hygiene education to patients preoperatively. Patients enrolled in the study will be given a dysphagia screening questionnaire, an oral care package and oral hygiene education. Patients who screen positive for dysphagia will be referred to Speech Pathology for evaluation. The rate of postoperative pneumonia will be determined for those who participate in the study and will be compared to retrospective patient data from our institution.
The employ of medical images combined with deep neural networks to assist in clinical diagnosis, therapeutic effect, and prognosis prediction is nowadays a hotspot. However, all the existing methods are designed based on the reconstructed medical images rather than the lossless raw data. Considering that medical images are intended for human eyes rather than the AI, we try to use raw data to predict the malignancy of pulmonary nodules and compared the predictive performance with CT. Experiments will prove the feasibility of diagnosis by CT raw data. We believe that the proposed method is promising to change the current medical diagnosis pipeline since it has the potential to free the radiologists.
This is a phase 3, multi-center, single dose, open-label, exploratory study in suspected lung cancer patients scheduled to undergo endoscopic or thoracic surgery per CT/PET/MRI or other imaging based on standard of care. This study aims to assess the efficacy of OTL38 and Near Infrared Imaging (NIR) at identifying pulmonary nodules within the operating theater, and to assess the safety and tolerability of single intravenous doses of OTL38.
Screening at-risk subjects with low-dose computed tomography (CT) efficiently reduces lung cancer specific mortality. However screening efficiency relies on the at-risk population's criteria definition and its participation rate to the screening. In France, there are concerns regarding the participation rates to national cancer screening that are quite low (around 50% and 32% of the eligible population for breast cancer and colorectal cancer respectively). Before organizing national lung cancer screening it is then crucial to determine the factors impacting the at-risk subjects willingness to participate in lung cancer screening. The Lyon University Hospital is the second biggest hospital in France with more than 23,000 employees distributed among more than 160 professions representing every level of education or working conditions. Its population is heterogeneous and wide enough to perform a prevalence study assessing the willingness to participate among the at-risk population. ILYAD is a prospective study performed by anonymous questionnaires that will be submitted to the 23,000 employees of the Lyon University Hospital. The study main objective is to evaluate the at-risk population presence in the Lyon University Hospital population, as defined by NELSON criteria and selection criteria for lung cancer screening (PLCOm2012 scoring), and its willingness to participate to a lung-cancer screening with low-dose CT. This might help further efficient national lung cancer screening campaign organization.
Explore the randomized, controlled, double-blind design targeted for the final clinical trial to assess the acceptability of interventions and clinical outcome measures and to provide data making it possible to estimate the parameters necessary for the preparation, modification or even abandonment of the final study.
