Noninvasive detection of lung cancer using exhaled breath
Early detection of lung cancer is a key factor for increasing the survival rates of lung cancer patients. The analysis of exhaled breath is promising as a noninvasive diagnostic tool for diagnosis of lung cancer. We demonstrate the quantitative analysis of carbonyl volatile organic compounds (VOCs) and identification of lung cancer VOC markers in exhaled breath using unique silicon microreactor...
متن کاملDiagnosing lung cancer in exhaled breath using gold nanoparticles.
Conventional diagnostic methods for lung cancer are unsuitable for widespread screening because they are expensive and occasionally miss tumours. Gas chromatography/mass spectrometry studies have shown that several volatile organic compounds, which normally appear at levels of 1-20 ppb in healthy human breath, are elevated to levels between 10 and 100 ppb in lung cancer patients. Here we show t...
متن کاملExhaled Breath Analysis for Monitoring Response to Treatment in Advanced Lung Cancer.
INTRODUCTION The Response Evaluation Criteria in Solid Tumors (RECIST) serve as the accepted standard to monitor treatment efficacy in lung cancer. However, the time intervals between consecutive computerized tomography scans might be too long to allow early identification of treatment failure. This study examines the use of breath sampling to monitor responses to anticancer treatments in patie...
متن کاملOxidative Stress and Exhaled Breath Analysis: A Promising Tool for Detection of Lung Cancer
Lung cancer is one of the few neoplasia in which the principal aetiology is known, with cigarette smoke donating a considerable oxidative burden to the lungs. This may be part of the aetiology of lung cancer, but the neoplastic process is also associated with increased oxidative stress. Nonetheless, it is difficult to study the mechanisms behind the induction of lung cancer in smokers, but newe...
متن کاملExhaled Breath Analysis for Lung Cancer Detection Using Ion Mobility Spectrometry
BACKGROUND Conventional methods for lung cancer detection including computed tomography (CT) and bronchoscopy are expensive and invasive. Thus, there is still a need for an optimal lung cancer detection technique. METHODS The exhaled breath of 50 patients with lung cancer histologically proven by bronchoscopic biopsy samples (32 adenocarcinomas, 10 squamous cell carcinomas, 8 small cell carci...
