Filter by:This randomized phase II trial studies acetylsalicylic acid compared to placebo in treating high-risk patients with subsolid lung nodules. A nodule is a growth or lump that may be malignant (cancer) or benign (not cancer). Chemoprevention is the use of drugs to keep cancer from forming or coming back. The use of acetylsalicylic acid may keep cancer from forming in patients with subsolid lung nodules.
The purpose of this study is to compare the yield of two methods for obtaining a lung tissue sample: Procedure #1: standard fiberoptic bronchoscopy (FB) with fluoroscopy, and Procedure #2: ultrathin bronchoscope procedure with fluoroscopy and radial endobronchial ultrasound (R-EBUS). These two procedures are similar in that they both: (1) enable your doctor to look inside your lungs with a device called a bronchoscope, and (2) Use fluoroscopy, which is a technique that uses X-rays to see your lungs. This will give the doctor an opportunity to use either of the bronchoscopy methods described above and compare the tests to see if R-EBUS provides better results than standard bronchoscopy.
The goal of this study is to evaluate the feasibility and safety of navigation guided virtual transthoracic needle biopsy combined with navigational bronchoscopy for the diagnosis of peripheral pulmonary nodules (PPN).
The purpose of this study is to determine whether J-shaped thoracophrenolaparotomy is effective in the surgical treatment of simultaneous liver and right lung metastases from colorectal cancer
This study will determine the feasibility of the novel Indocyanine Green (ICG) fluorescence localization technique with a Laser fluorescence thoracoscope system. The primary objective of this study is to prove the validity and safety of our novel fluorescent localization method with utilized ICG and novel near infra-red fluorescence videoscope system.
Title ThoHSpEkt Study Design Pilot Study concerning the technical operative methods and a phase II study concerning the radiopharmaceutical (therapeutic-explorative study with an approved drug in a new indication) Location Kantonsspital St.Gallen Aim Proof of feasibility of thoracoscopic ectomy of radioactively marked pulmonary nodules with the help of free-hand SPECT. Background In the Cantonal Hospital of St.Gallen an average of 30 - 40 patients will be operated with thoracoscopic ectomy for a pulmonary nodule. When localisation of the nodule is not possible a switch to minithoracotomy is performed. Study intervention Marking of pulmonary nodules with radioactivity. Free-hand SPECT guided surgery Risks Risks of bronchoscopic or CT-intervention Radiation risk (minimal) Rational for patient number 10 patients for each group are enough to prove the feasibility, to manage difficulties and to record complications Duration approximately 24 months.
A small proportion of patients with lung cancer present with a solitary pulmonary nodule (SPN). This is an important group of patients because if it is lung cancer, presentation as a SPN represents early disease, which following surgery has a high 5 year survival rate. However as not all SPNs are lung cancer it would be unethical to biopsy every case. Clinical guidelines recommend that SPNs should undergo an initial (FDG)-PET/CT scan, which may give more information about the SPN and may indicate if it is likely to be lung cancer. However in many cases it does not and current practice is to monitor the SPN with a series of CT scans over 2 years to look for changes or growth which may/ but not always indicate lung cancer. If no changes are observed over 2 years the SPN is considered not lung cancer. This is both expensive for the National Health Service (NHS) and worrying for the patient in terms of monitoring CT costs and delayed treatment due to length of time to diagnosis. This study examines the diagnostic capacity of using a different CT scan. Dynamic Contrast Enhanced -CT(DCE-CT). DCE-CT and FDG-PET/CT scans give different information about the SPN and the investigators will look to see if information from either scan or combined information from both scans may be better in the diagnosis of early stage lung cancer. The investigators will also undertake a review of previous studies that have used these scans and use data from both the review and the trial to look at the cost effectiveness of using DCE-CT in the diagnosis of SPN. The trial will recruit 375 people who have a SPN detected by a normal CT scan which requires a FDG-PET/CT scan. In addition they will receive a DCE-CT scan either on the same day or within three weeks of the FDG-PET/CT scan. This is the only extra procedure that will take place to normal NHS care, however we will collect clinical and outcome data over the next two years. The study is coordinated by Southampton University clinical trials unit. Recruitment between January 2013 - April 2016, from up to 14 UK sites. Data analysis and conclusions are expected by the end of 2018. The study is funded by the NIHR-HTA
A Study to evaluate the utility of the ProLung Test as an adjunct to CT scan in the diagnosis of lung cancer.
Solitary pulmonary nodule has become a major challenge in respiratory clinical practice. According to published guidelines, their management often requires close CT follow up, PET CT and invasive procedures to obtain a definite histology. In this context, innovative endoscopic techniques refered as navigational bronchoscopy have proved to be efficient, for the localization and sampling of peripheral lung nodules. However, these techniques are unable to differentiate malignant lesions from benign ones, in-vivo, in real time. Confocal endo-microscopy (CELLVIZIO) of the distal lung - also refered as distal lung probe based confocal laser endo-microscopy or alveolar lung endo-microscopy - allows in-vivo imaging of the distal lung structures in real time. This prospective trial we will assess confocal endoscopy as a tool to localize the peripheral lung nodules and to differentiate benign from tumoral lesions. Objective(s) 1. To demonstrate that confocal endo-microscopy is not inferior to navigational endoscopy for the localisation of peripheral lung nodule 2. To demonstrate that confocal endoscopy can differentiate benign from malignant tumors Experimental design: Multicentric prospective controlled trial, conducted in three academic centers, specialized in interventional bronchoscopy, equipped with both navigational bronchoscopy and probe based confocal endo-microscopy. Subjects with peripheral lung nodule requiring navigational bronchoscopy will be explored using both Confocal endoscopy AND navigational bronchoscopy. Confocal probe will be inserted in the same catheter as used for the navigational bronchoscopy and confocal images will be recorded before sampling. An ancillary study using topical methylene blue as in situ will be conducted at the Rouen University Center. An ancillary protocol includes the use of in situ methylene blue deposition and 660 confocal endo-microscopy analysis.
The goal is to improve the efficiency of the diagnostic follow-up of patients with indeterminate pulmonary nodules by determining whether biomarkers for lung cancer diagnosis that are measured in minimally invasive biospecimens are able to distinguish malignant from benign pulmonary nodules that are incidentally detected in high-risk smokers.
