Active clinical trials for "Lung Neoplasms"

This is a clinical trial from Eastern Cooperative Thoracic Oncology Project (ECTOP), numbered as ECTOP-1003. Systemic mediastinal lymphadenectomy is deemed indispensable in lung cancer surgery for accurate staging and complete resection. However, extensive lymphadenectomy in patients without nodal metastasis may not improve survival and would increase operative duration and cause damage to mediastinal structures.Therefore the precise selection of patients without mediastinal nodal metastasis is the key to avoid unnecessary lymphadenectomy.The investigator's previous retrospective study shows tumor location, ground glass opacity component and histological subtypes are important predictors of negative nodal status in specific mediastinal regions. The current prospective observational study is to further verify the mediastinal staging accuracy of this selective lymphadenectomy strategy.

The assessment of the type and frequency of EGFR and KRAS mutations in lung cancer patients, as well as clinical-prognostic correlation, are crucial in the era of targeted therapies. EGFR-activating mutations predict responsiveness to EGFR tyrosine kinase inhibitors (TKIs) in non-small cell lung cancer (NSCLC) patients and KRAS analysis will be useful in a near future for newest target drugs. In Brazil, few data about the prevalence of EGFR and KRAS mutations is available and their knowledge would allow optimize personalized medicine.

Prospective validation of a prognostic model based on advanced PET/CT image analysis in non small cell lung cancer

A study to describe and evaluate patient characteristics and clinical outcomes in Subjects with diagnosed Non Small Lung Cell Cancer in Sweden, Norway and Denmark.

In this study the investigators will collect Blood,sputum and saliva samples for Characterization of Methylation Patterns in lung Cancer.

The purpose of this study is to isolate and measure circulating tumor cells in the blood stream to advance detection of cancer and treatment monitoring. In this study, the investigators will utilize the novel technology for circulating tumor cell detection in order to evaluate their presence in patients with lung cancer.

Postoperative venous thromboembolism (VTE) is a significant health-care problem, resulting in significant morbidity, mortality and resource utilization. The true incidence is unknown, and may range from 1% to 15%. At the current time, the clinical practice of VTE prophylaxis in thoracic surgery includes administration of unfractionated or low molecular weight heparin starting at the perioperative period and finishing at the time of patients' discharge. In orthopaedic surgery, prolonged thromboprophylaxis beyond 10 days and up to 35 days has become the standard of care. There is a clear need to systematically evaluate the incidence of VTE after resection of lung malignancies and to evaluate the role of extended VTE prophylaxis in preventing Deep Vein Thrombosis (DVT) and pulmonary embolus (PE) after those major lung resections. This study will involve patients undergoing lung resection for malignancy at St. Joseph's Healthcare Hamilton and the University Health Network's Toronto General Hospital. The study will include 150 consecutively recruited patients. Study interventions will include Computed Tomography with pulmonary embolus (PE) protocol and bilateral extended leg Doppler Ultrasound for the detection of Deep Vein Thrombosis 30 days post-surgery. In summary, this study is aimed at evaluating, for the first time in a prospective manner, the actual incidence of DVT and PE in patients undergoing major lung resections for malignancies. The knowledge gained in this study will be used to inform a future investigation involving a Randomized Controlled Trial (RCT) to compare current post-operative thromboprophylaxis with an extended 30-day prophylaxis protocol with the hope of providing an evidence-based practice change in VTE prophylaxis care for this high risk population.

NovellusDx technology identifies tumor-specific driver mutations, but unlike sequencing-based tests, NovellusDx has a functional assay that detects dis-regulated translocation of mutated signaling proteins to the nucleus. This allows NovellusDx to identify functionally-impactful driver mutations regardless of whether the mutation has previously been described or linked to a tumor type.

This study aims to test the use of novel CT image analysis techniques to enable a better characterisation of small pulmonary nodules. The study will incorporate solid and predominantly solid nodules of 5-15 mm scanned using a variety of scanner types, imaging protocols and patient populations. The investigators hope that the new image processing techniques will improve the accuracy of lung nodule analysis which will in turn reduce the number of unnecessary investigations for benign nodules and may increase the accuracy of the early diagnosis of lung cancer in malignant nodules. This study aims to test this novel analysis software to subsequently allow validation.

To understand the mechanism and cellular functions of PTK7-associated signaling pathways in promoting lung cancer progression and conferring treatment to epidermal growth factor receptor tysosine kinase inhibitors (EGFR TKIs).
