Lung cancer is usually detected at an advanced stage. Attempts at demonstrating the benefits of screening and early detection had been elusive, until the results of the National Lung Screening Trial (NSLT), sponsored by the National Cancer Institute, were published in the
New England Journal of Medicine on Aug. 4, 2011.
Stereotactic body radiotherapy (SBRT) provides better overall survival rates than surgery for lung cancer patients with severe chronic obstructive pulmonary disease (COPD), a disease commonly associated with lung cancer, according to a study in the upcoming March issue of the International Journal of Radiation Oncology•Biology•Physics.
Chronic obstructive pulmonary disease (COPD) is a major cause of death in heavy smokers, yet it remains substantially underdiagnosed. There are some promising signs, however, as researchers have shown that low-dose inspiratory and expiratory CT scans obtained for lung cancer screening of men who are current and former heavy smokers can identify patients with COPD, according to a study published in the Oct. 26 issue of
Journal of the American Medical Association.
Providing portable computed radiography chest studies in the homes of elderly patients provided satisfactory image quality and lowered delirium among patients, according to a small pilot study published as a research letter Aug. 8 in
Archives of Internal Medicine.
Researchers have leveraged quantitative CT to identify two types of structural changes in the lungs of patients with chronic obstructive pulmonary disease (COPD) associated with frequent exacerbations, according to a study published online July 25 in Radiology. The findings may help identify patients for targeted research and therapy development for individual phenotypes.
Researchers have developed and validated a weighted scoring system that incorporates patient- and scan-related factors to predict pre-coronary CT angiography (CCTA) risk of an uninterpretable result in symptomatic patients, according to a study published online July 26 in
Circulation: Cardiovascular Imaging.
