Filter by:In the past few years, circulating tumor cells (CTCs), circulating tumor DNA (ctDNA), microRNAs, autoantibodies, and T-cell receptor repertoire are new biomarkers of liquid biopsy in cancer, which has been demonstrated to have a great value in diagnostics, treatment evaluation, and prognosis prediction. However, most of previous data were based on late stage tumor patients. This study plans to utilize the minimally invasive method to detect the changes of numbers of CTCs, ctDNA hot spot mutations and methylation signals, microRNAs, autoantibodies, and T-cell receptor repertoire in early stage lung cancer patients before and after pulmonary nodule biopsy, during therapeutic and follow-up periods, in order to evaluate the clinical values of above tumor-related biomarkers.
Medical The Internet of Things (IoT), a recent breakthrough in communication technology, could be helpful in improving health care delivery and saving medical costs, but regarding pulmonary nodule management it is still at the basic understanding. Investigators adopt "Internet of things medical three plus two type pulmonary nodule diagnosis" which chun-xue Bai put forward, used a developed a mobile phone-based IoT (mIoT) platform and initiated a randomized, multicenter, controlled trial to value clinical effectivity of "Internet of things medical three plus two type pulmonary nodule diagnosis" in the management of pulmonary nodules. In this study, at least 600 patients with pulmonary nodules (no typical symptoms, often single, clear boundary, increased density, soft tissue shadow surrounded by lung parenchyma with diameter ≤3 cm) will be randomly allocated to the control group, which receives routine follow-up, or the intervention group, which receives "Internet of things medical three plus two type pulmonary nodule diagnosis" management. Endpoints of the study include: (1) The positive diagnosis rate of lung cancer in I stage; (2) 5 year disease-free survival rate and overall survival rate; (3) direct medical costs per year. Results from this study should provide direct evidence for the suitability of "Internet of things medical three plus two type pulmonary nodule diagnosis" in pulmonary nodules patients management.
A Study to evaluate the utility of the ProLung China Test as an adjunct to CT scan in the diagnosis of lung cancer.
Patients with lung nodules may develop a variety of potentially severe symptoms. These symptoms may impact a patient's quality of life and lead to difficult treatment. Through this research program, the investigators want to understand the pathogenesis of the changes of these symptoms.
The Guided Therapeutics (GTx) program at the University Health Network is a network of clinicians, scientists, and engineers focused on the development and translation of image-guided technologies focused on minimally-invasive, adaptive therapies. Technologies developed within the GTx program include a portable intra-operative cone-beam CT (in collaboration with Siemens) that has been evaluated in clinical trials for head and neck surgery. The intraoperative imaging has been integrated with tracking and navigational tools and optical imaging to provide a general "surgical dashboard" that is used to improve the accuracy of surgical resection. A recent addition to the GTx program is the development of the GTx OR, located within the general operating room of the Toronto General Hospital. The GTx OR houses 2 complimentary advance technologies: the Siemens Zeego and the Siemens Somotom Flash CT. The dual-energy Somatom Flash provides a "gold-standard" in CT imaging, while the Zeego provides excellent 3D Cone-beam CT with robotic placement for flexible integration within the operating environment. Together, the integration of these 2 components into a single OR enables critical evaluation of the limits of CT imaging technology for surgical guidance. This study will be conducted using solely the Cone-beam CT (Zeego) for percutaneous placement and localization of markers for resection of small pulmonary nodules during VATS.
To investigate the diagnostic value of ultralow-dose computed tomography in the detection of pulmonary nodules and lung parenchym alterations (e.g. emphysema) compared to standard-dose-CT.
This study evaluates the value of different bronchoscopy combination for diagnosing peripheral pulmonary lesions suspected to be cancer. One-third of participants will receive routine bronchoscopy, while one-third of participants will receive bronchoscopy combined with a guiding equipment and the other one-third of participants will receive bronchoscopy combined with two or more guiding equipments. These guiding equipments include virtual bronchoscopic navigation(VBN), endobronchial ultrasonography with a guide sheath(EBUS-GS) and fluoroscopy.
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
The study aims to determine if there are defining EBUS and confocal endoscopy features as well as exhaled alveolar gas VOC that can discriminate malignant pulmonary nodules or masses from benign etiology, thereby obviating unnecessary thoracotomy. Directly sampled alveolar gas VOC from patients with lung cancer will be compared against exhaled breath VOC for signature compounds that may complement CT in screening the population at risk.
