Filter by:This is a multi-center, non-randomized, single-arm, prospective trial to evaluate a staged sampling methodology designed to maximize the diagnostic yield of lung biopsy in a single procedure setting.
Analyse immune repertoire and genetic mutations of benign and malignant pulmonary nodule，and evaluate peripheral blood detection for identifying nature of pulmonary nodule.
Lung cancer screening programs are still discussed in Europe today, and one of the concern is radiation due to iterative CT. The aim of this monocentric, prospective, non randomized study is to compare an ultra low dose chest CT (approaching a two views X ray) versus a standard low dose chest CT for ≥4mm lung nodules detection, and secondary for lung nodule characterization and smoking associated findings (emphysema, bronchial abnormalities and coronary calcifications).
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.
Current state-of-the-art lung cancer early screening utilizes low-dose CT scan to identify lung nodules smaller than 3 cm in diameter. However, it's still a clinical challenge to differentiate between malignant and benign nodules. In previous studies, the investigators had taken the approach of methylation profiling by high throughput bisulfite DNA sequencing in tissue samples to identify specific methylation signatures. The investigators had learned methylation patterns that differentiate malignant vs. benign lesions from tissue samples by in-depth data mining, and then used pattern matching to classify plasma samples. In this study, the investigators are going to validate the efficacy of ctDNA methylation test for diagnosing early lung cancer by comparing results of the pre-surgery ctDNA methylation test with the post-surgery pathology.
We will perform an ultra low-dose CT (ULDCT) in addition to a regular chest CT scan for adult patients undergoing a clinically indicated chest CT. Using a recently developed computationally efficient algorithm for the denoising of ULDCT scans after image reconstruction, we will compare the sensitivity, specificity and accuracy of lesion detection with the ULDCT as compared to the regular CT scan.
This is a clinical trial to evaluate the intravenous administration of indocyanine green (ICG) as a method of intra-thoracic lesion localization. The primary purpose is to determine if intravenous ICG allows us to identify intra-thoracic lesions.
The aim of this study is to study the safety and effectiveness of the effects on the perioperative pain control comparing between the thoracic paravertebral nerve block using the camera guided and the intrathoracic intercostals nerve block for the management of nonintubated local regional analgesia in uniport thoracoscopic surgery for the undetermined solitary nodules patients.
The trial is to evaluate the efficacy and safety of three-dimensional printed navigational template in the clinical application of small peripheral lung nodule localization.
This research study will evaluate how Near Infrared Fluorescence imaging (NIFI) with indocyanine green (ICG) contrast dye can assist in the identification and diagnosis of lung nodules during surgery. NIFI is an intraoperative imaging technology that utilizes a coupled camera/fluorophore (ICG) system to fluoresce tissues of interest. Intravenous ICG is a fluorophore with a long-standing high safety profile.
