Active clinical trials for "Lung Neoplasms"

The primary outcome of this study is to investigate the accuracy of respiration gated laser guided CT lung nodule biopsy through a prospective randomized trial using a bellows-based breath hold monitoring system. Secondary outcome is the rate of complications using laser guided CT biopsy in general and with bellows-based breath hold monitoring system. The study has approval from the The Danish National Committee on Biomedical Research Ethics (ref no: H-4-2010-fsp 1).

Lung cancer remains the leading cause of mortality from malignant diseases in both men and women worldwide. Accurate diagnosis, staging and therapeutic targeting of lung cancer and other pulmonary pathology are vital with regards to providing patients with expedient and accurate treatment and treatment plans. The pre-operative evaluation and consultation in patients who are to undergo operative staging or resection for lung cancer is multidimensional and involves detailed history taking, physical examination and review of imaging studies. Two important elements of both staging and pre-operative evaluation include the evaluation of: (1) the pleural space for malignant pleural effusion and (2) the diaphragm for appropriate movement. At this point in time, the pleural space evaluation is being performed using CT scan which does not allow the acquisition of real-time cytological material from pleural effusions due to the fact that the CT scans are done in a diagnostic setting. Diaphragmatic movement/excursion is not currently being assessed pre-operatively and its impact on staging and post-operative pulmonary function is unknown. Malignant pleural effusion is recognized as a poor prognosticator in non-small cell lung cancer patients and has recently been upgraded from a T4 to an M1a status in the new edition of the AJCC NSCLC Staging System (7th Edition). The appreciation of the poor prognosis related to malignant effusion has upgraded the stage from a Stage IIIb to a stage IV. Recognizing the stage early allows for more precise prognostication of disease and can lead to precision and streamlining of treatment plans for thoracic surgeons and oncologists.

This is a pharmacogenomic study with carboplatin, paclitaxel and bevacizumab as first line therapy in patients with non-squamous advanced non-small cell lung cancer.

That computed tomography (CT) screening of HIV-seropositive heavy smokers will detect early stage lung cancer at significantly higher rates than what is currently being observed.

To demonstrate and validate a breath test for detection of early stage lung cancer that could potentially reduce number of deaths.

Early detection of lung cancer may improve treatment outcomes. Risk factors have been identified, suggesting a population which might benefit from regular screening. Lung cancer screening using low-dose computed tomography (LDCT) has experienced a recent renaissance with reported sensitivity for detection of lung cancer of 2.7% in high-risk populations. The purpose of this study is to evaluate the utility of LCDT for the early diagnosis of lung cancer in Ontario.

The purpose of this study is to try to learn more about how small molecule kinase inhibitors work in treating lung cancer. Some early studies have shown that gefitinib, erlotinib and similar drugs are more likely to work if a particular DNA change (also known as a mutation) is found in a protein that is important in lung cancer. This protein is called the epidermal growth factor receptor (EGFR). Since small molecule kinase inhibitors sometimes stop working, we would like to examine your tumor to learn why these medicines are not working as well. Your tumor will be examined for a variety of things including changes in the DNA of the EGFR. We will also sequence parts of the genes for HER2, HER3, HER4, and KRAS, other proteins thought to be important in lung cancer.

The purpose of this study is to compare the results of two CT scans of the chest performed within minutes of each other. We will compare several different measurements of lung cancer tumors. This study will help show whether we can get accurate results when we compare measurements on different CT scans. This information is important for patients with cancer, who often have more than one CT scan during their treatment.

To study changes in tumor and normal organ size and/or position which occur during a course of radiation treatments.

Primary Objective: To estimate the accuracy of the pre-operative VRI QRF (Quantitative Regional Function) results versus the gold standard QRRVP (Quantitative Radionuclide Study of Regional Lung Ventilation and Perfusion) pre-operative scan. Secondary Objective: To assess the correlation of the predicted post-operative lung function with the observed post-operative lung function (FEV1 and DLCO) in patients who underwent surgical resection. (FEV1 = Forced expiratory volume in 1-second. DLCO = Diffusion capacity for carbon monoxide. ppo = predicted postoperative.)
