Active clinical trials for "Multiple Pulmonary Nodules"

The purpose of the study is the identification of the efficacy of MDA Test to Differentiate of Benign and Malignant Pulmonary Nodules. In this study, the investigators are going to validate the efficacy of the MDA test for diagnosing early lung cancer by comparing results of the pre-surgery MDA test with the post-surgery pathology.

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 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 ACRIN 7151 trial will use medical records abstraction data from participants with extracolonic findings (ECFs) reported from the ACRIN 6664 National CT Colonography Trial to: 1) measure incidence of diagnostic imaging, hospitalization, and interventional procedures associated with ECFs reported on computed tomography colonography (CTC), delineated by type of ECF; 2) determine potential predictors of follow-up diagnostic imaging, hospitalization, and interventional procedures, delineated by type of ECF; and 3) evaluate the clinical/pathologic diagnoses associated with indeterminate but potentially significant ECFs. These data can be used to incorporate ECFs into existing models on the cost-effectiveness of CTC in colorectal cancer screening and can potentially be used to develop guidelines for the reporting and management of ECFs.

By testing the CTC number of new solitary pulmonary nodule patient, evaluating the correlation of CTC number and benign and malignant lung nodules auxiliary diagnosis, the correlation of CTC number and the size of lung nodules of the malignant patients, the correlation between the CTC number and subtypes of malignant lung nodules patients.The CTC and tumor markers will be detected before the patient received treatment. Tumor markers include Pro-GRP, NSE, CEA, CYFRA211, SCC.

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.

This study will collect retrospective CT scan images and clinical data from participants with incidental lung nodules seen in hospitals across London. The investigators will research whether machine learning can be used to predict which participants will develop lung cancer, to improve early diagnosis.

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 is conducted to explore the feasibility and value of Intraoperative ultrasonographic localization of pulmonary nodules in video-assisted thoracoscopic surgery (VATS).

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.
