Localization is the key for successful excision of small target nodules under thoracoscopy, but the procedure also brings risks to patients. However, the criteria is still unclear. The investigators will validate the prediction model produced by institutional retrospective analysis in the prospective cohort.
The study objectives are as follows: - To determine the safety of trial 18F-2-fluoro-2-deoxy-D-glucose, produced by a new manufacturer, by surveillance for adverse events in patients having Positron Emission Tomography Computed Tomography scans in a comprehensive program for indications including, but not limited to, oncology, neurology, cardiac and infectious/inflammatory processes. - To determine the efficacy of 18F-2-fluoro-2-deoxy-D-glucose Positron Emission Tomography in differentiating benign from malignant solitary pulmonary nodules and calculate sensitivity, specificity, and accuracy using pathologic confirmation as the gold standard when available, or greater than 6 month follow up stability on Computed Tomography scan when not. The purpose of performing this clinical trial is to provide local access of 18F-2-fluoro-2-deoxy-D-glucose to the patients of Newfoundland and Labrador. This product has been offered to patients over the last three years by transporting from facilities outside of the province. There have been significant delays in access and in fact, times where 18F-2-fluoro-2-deoxy-D-glucose has not been available through this process. This has caused delays and limitations of treatments for patients who rely on Positron Emission Tomography Computed Tomography scans for diagnosis.
The purpose of this study is to evaluate the effectiveness of a smoking cessation outreach intervention (TeaM OUT) on increasing use of smoking cessation resources in Veterans. The hypotheses are 1) patients included in the TeaM OUT group will have higher accession of cessation services, such as counseling and medication therapies, compared to patients in enhanced usual care and 2) more patients in the TeaM OUT group will have quit smoking at one year after the intervention. Veterans with a recently diagnosed lung nodule who currently smoke will receive the TeaM OUT intervention or Enhanced Usual Care. The TeaM OUT intervention has 2 parts: 1) a letter that a) describes the nodule and the importance of cessation related to the pulmonary nodule (i.e. teachable moment) and b) notification that a Proactive IVR Quit Line will initiate contact and 2) call(s) from the Proactive IVR Quit Line which a) offers smoking cessation resources and b) helps connect the patient to those resources. The enhanced usual care group will receive a letter that provides information about how to contact the IVR Quit Line. The IVR system will track referrals to cessation services. Additional information about smoking status and use of cessation resources will be collected from the electronic health record and surveys. .
Pulmonary cryptococcosis often manifests as isolated or multiple nodules, easily mimicking lung cancer clinically and radiologically, which ascribes the poor sensitivity of Cryptococcus culture and rarely positive of Cryptococcal antigen test in the absence of disseminated disease. Therefore, the aim of this study was to develop a predictive scoring system from the perspective of available clinical indicators, to differentiate cryptococcosis from adenocarcinoma in pulmonary nodules, which might be beneficial for the delicacy management of pulmonary nodules.
This study evaluates the viability and accuracy of preoperative mixed reality technique combined with three-dimensional printing navigational template guided localizing pulmonary small nodules.
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
evaluate the diagnostic performance of ultra-low dose CT using deep learning-based reconstruction in the detection of pulmonary nodules.
The standard procedure in the diagnosis of peripheral round foci is bronchoscopy with transbronchial forceps biopsy (TBB). Despite the simultaneous application of X-ray fluoroscopy, the diagnostic value of this method depends strongly on the size, location and relationship of the foci to the airways as well as their radiological representability. By inserting radial 20 MHz ultrasound probes through the working channel of a flexible bronchoscope into the periphery of the lung, the detection of peripheral foci can be improved. By simultaneously using a virtual bronchoscopy with an ultra-thin bronchoscope, even smaller round foci in the periphery of the lung can be detected. For some years now, tension-resistant cryoprobes have been used for transbronchial biopsy. Here, especially in lesions that can only be reached endoscopically tangentially, advantages have been shown over forceps biopsy. Much larger tissue samples can be obtained without increasing the complication rate. Studies showed that the combination of the EBUS navigation technique with the cryobiopsy procedure is feasible and safe in the endoscopic diagnosis of peripheral lung tumors. This study investigates to what extent the combination of an ultra-thin cryoprobe with an ultra-thin bronchoscope together with the radial EBUS can further improve the diagnosis. This study is a non-randomized pilot study to prove the feasibility of this procedure. The EBUS probe and the bronchoscope are CE certified for this application. The study will be conducted as a monocentric study at the Thorax Clinic at Heidelberg University Hospital. A total of 30 patients with an indication for transbronchial biopsy will be prospectively included. All patients will be examined according to the clinical standard. After a freezing time of 3-7 seconds, the probe together with the bronchoscope will be extracted and the sample will be defrosted in a water-filled sample vial. Up to 4 biopsies will be taken depending on the investigator's assessment. The samples will be collected separately and the order of the biopsies will be recorded. The primary endpoint is the feasibility of the procedure. Secondary endpoints are safety, diagnostic hit rate, biopsy size and quality and success rate depending on the position of the EBUS probe (tangential or central).
The broad goals of this study is to identify changes in genomic landscape during transition from stage 0 to stage 1 lung cancer. This study intends to determine whether diagnostic biomarkers measured in minimally invasive biospecimens are able to correlate molecular, clinical and imaging features to distinguish malignant from benign pulmonary nodules. The diagnostic markers once validated can be used as broad screening tools for lung cancer.
