Introduction: Lung cancer is the most common and most deadly cancer in most of countries of the world. One of the most significant problems with this cancer is the lack of accurate and specific statistics about the prevalence and mortality rate in Iran. Results of cancer registry program in 2008 in Iran indicated a low incidence rate of lung cancer. However, these statistics...
متن کاملReduced lung-cancer mortality with low-dose computed tomographic screening.
BACKGROUND The aggressive and heterogeneous nature of lung cancer has thwarted efforts to reduce mortality from this cancer through the use of screening. The advent of low-dose helical computed tomography (CT) altered the landscape of lung-cancer screening, with studies indicating that low-dose CT detects many tumors at early stages. The National Lung Screening Trial (NLST) was conducted to det...

BACKGROUND Mortality outcomes in trials of low-dose computed tomography (CT) screening for lung cancer are inconsistent. This study aimed to evaluate whether CT screening in urban areas of China could reduce lung cancer mortality and to investigate the factors that associate with the screening effect. METHODS A decision tree model with three scenarios (low-dose CT screening, chest X-ray scree...
متن کاملBetter evidence about screening for lung cancer.
In October 2010, the National Cancer Institute (NCI) announced that patients who were randomly assigned to screening with low-dose computed tomography (CT) had fewer deaths from lung cancer than did patients randomly assigned to screening with chest radiography. The first report of the NCI-sponsored National Lung Screening Trial (NLST) in a peer-reviewed medical journal appears in this issue of...
متن کاملRadiation risks potentially associated with low-dose CT screening of adult smokers for lung cancer.
PURPOSE To estimate the radiation-related lung cancer risks associated with annual low-dose computed tomographic (CT) lung screening in adult smokers and former smokers, and to establish a baseline risk that the potential benefits of such screening should exceed. MATERIALS AND METHODS The estimated lung radiation dose from low-dose CT lung examinations corresponds to a dose range for which th...

OBJECTIVES This study aim to compare image quality and radiation doses between low-dose CT and follow-up standard diagnostic CT for lung cancer screening. METHODS In a single medical institution, 19 subjects who had been screened for lung cancer by low-dose CT before going through follow-up standard diagnostic CT were randomly selected. Both CT image sets for all subjects were independently e...
