Filter by:In addition to their role in allergic inflammation, mast cells are often found at the site of tumors. They have been attributed both to pro- and anti-tumorigenic roles depending on the tumor type. Secretion of mast cell mediators such as histamine, tryptase, fibroblast growth factor (b-FGF), vascular endothelial growth factor (VEGF) and interleukin-8 (IL-8) can enhance tumor growth and angiogenesis while TNF-a and heparin act as tumor suppressors. The non-small cell lung cancer constitutes the majority of cases of lung cancer. In lung cancer, mast cell numbers correlate with tumor angiogenesis and poor prognosis. In this work, we are interested to determine the factors in lung cancer microenvironment that attribute to mast cell activation. Beside the tumor cells themselves, the cancer microenvironment includes other cells such as fibroblasts. The fibroblasts arising from tumor stroma, called cancer-associated fibroblasts (CAFs), undergo activation, and have different feature compared to normal fibroblasts (NFs). In this work we are interested to determine whether CAF cells derived from lung tumors, together with the lung cancer cells, or microvesicles-derived from these cells, are able to stimulate mast cells to degranulate and/ or to release various cytokines and chemokines. For this propose, during surgery of patients with lung cancer, we will take unnecessary sample from the cancer and from normal area for purification of CAF or normal fibroblast cells. Those cells will be co-cultured with both lung cancer cell line (A-549) or microvesicles-derived from these cells, and human mast cell line (LAD2). Supernatants will be collected for determine degranulation and cytokine release from these mast cells.
EBUS-TBNA specimen are used for lung cancer diagnosing and staging, as well for molecular analysis. The purpose of this study is to evaluate if samples from on lymph node site can be divided for diagnosis and molecular analysis.
This is a phase 2 study. The goal of this study is to find out what effects, good and/or bad, taking erlotinib and ruxolitinib has on the patients and on lung cancer. Erlotinib and ruxolitinib are FDA approved for other indications, but the use of erlotinib and ruxolitinib together has not been studied before and is not FDA-approved.
Up to 85% experience shoulder pain after thoracic surgery, especially on the same side as surgery are performed. Referred phrenic nerve pain is probably one cause of ipsilateral shoulder pain (ISP), and positioning of the arm during surgery another. Studies indicates that ISP can be caused by the positioning of the patient during surgery due to muscle -and ligament strain. Can a change in the surgical positioning (less press and stretch) of the ipsilateral arm effect the shoulder pain after thoracic surgery?
Denutrition and Obesity are risk factors for perioperative surgical complications. In patient with cancer, incidence of denutrition is markedly increased. Surgical resection of cancer induces a high intensity cellular stress response and catabolism reinforcing the risk for perioperative denutrition. In this study, we thought to investigate the change in body composition during the perioperative period using anthropometric measurements and Bioelectrical Impedance Analysis (BIA).
The purpose of this study is to evaluate the safety and performance of the LungPoint ATV System.
Lung cancer kills 160,000 patients annually; this represents 28% of all US cancer deaths. The overall year survival rate has only improved from 12% to 17% in 33 years. This failure reflects the innate lethality of lung cancer, but also reflects defects in patient care delivery. Care for the lung cancer patient starts with an abnormal radiologic scan, proceeds through a diagnostic biopsy, tests to determine the extent of spread of the disease (stage), selection of appropriate treatment, and finally ends with patient outcomes. At each step are multiple options and independent specialists, each one engaged by a process of sequential referrals in the serial care model. This process is often not user-friendly, is riddled with inefficiency, delays, and outcome variances. The coordinated multidisciplinary model, in which patients and their doctors collaborate to provide evidence-based care, is believed by experts to be superior, but has few examples of successful implementation. The implementation gap exists because of the paucity of good quality data, and lack of implementation know-how. Embedded in the highest US lung cancer mortality zone, the greater Memphis area has a racially, culturally, economically and geographically diverse population. The investigators research group has shown how poor quality care impairs patient survival in this region and in the greater US. The investigators have linked patient survival to compliance with multidisciplinary care plans. In this project, the investigators propose to rigorously test the impact of the multidisciplinary care model on patient outcomes in a community-based, private practice environment, similar to where 70% of lung cancer care is delivered in the US. The objective of this study is to provide high-level evidence of the impact of multidisciplinary care on lung cancer patient outcomes. Multidisciplinary care is defined as a model of care in which patients, their care-givers and key specialists concurrently and directly evaluate the same patients in the presence of the patients and their informal caregivers, in order to develop evidence-based consensus care plans
Use of a microfabricated silicon device to concentrate ultra trace volatile organic compounds (VOCs) in human exhaled breath for quantitative analysis of VOCs.
The project aims to study whether the application of a continuous positive airway pressure (CPAP) of 4 cm water vapor is a safe method in pulmonary radiofrequency intervention (PRF) lung cancer under conscious sedation compared with placebo. And, assess whether CPAP prevents atelectasis formation and consequently reduces the potential complications of PRF and improves procedural success
Chest pain is an alarming symptom and one of the most frequent causes of access to the Emergency Departement. Although chest X-ray remains an essential step in the diagnostic process, several studies showed numerous limitations of radiography which frequently is inconclusive. Ultrasonography is a non-radiating imaging technique. Albeit a wide use of ultrasound, the utilization of ultrasound in the study of the lung has only recently been introduced in the clinical practice. Several studies proved that lung ultrasound is useful in the diagnosis of lung consolidation in community acquired pneumonia. Nowadays, ultrasound is not routinely used in the presence of chest pain. Our hypothesis based on clinical experience is that, in patients with pleuritic chest pain, lung ultrasound is very sensitive in detecting pneumonia and other lung diseases (such as pneumothorax) thus performing better than radiography. The primary aim of this study is to verify, in patients affected by pleuritic chest pain, the accuracy of lung ultrasound compared to chest-X-ray. The secondary aim is to evaluate the accuracy of lung ultrasound consolidations in distinguishing lung consolidation in pneumonia, atelectasis, pulmonary infarction, or tumors.
