Overview of observational studies of low-dose helical computed tomography screening for lung cancer.
OBJECTIVE Lung cancer is a substantial public health problem in Western countries. Evidence from previous controlled trials of chest radiography and sputum cytology does not support lung cancer screening, but computed tomography (CT) screening has recently emerged as a more sensitive screening tool. For the present article, the available observational studies of low-dose helical CT screening fo...
متن کاملLow-dose computed tomography lung cancer screening.
Lung cancers, primarily caused by tobacco smoking, are the leading cause of cancer deaths in the United States and around the world. Screening of select high-risk patients using low-dose helical computed tomography (LD-CT) has been shown to reduce lung cancer mortality by 20% compared with chest radiography. However, because there are risks to LD-CT lung cancer screening, it should be performed...
متن کاملHelical Computed Tomography (CT) for Lung Cancer Screening for Asymptomatic Patients
The overall prognosis for lung cancer is generally poor, with a 5-year survival rate less than 15%. In Minnesota, an estimated 2,300 new cases of lung cancer are diagnosed each year and approximately 2,200 individuals die of lung cancer.1 Despite evidence that early detection can result in substantially increased long-term survival, a number of clinical trials have not demonstrated a decrease i...
متن کاملBridging the clinical gaps: genetic, epigenetic and transcriptomic biomarkers for the early detection of lung cancer in the post-National Lung Screening Trial era
Lung cancer is the leading cause of cancer death worldwide in part due to our inability to identify which smokers are at highest risk and the lack of effective tools to detect the disease at its earliest and potentially curable stage. Recent results from the National Lung Screening Trial have shown that annual screening of high-risk smokers with low-dose helical computed tomography of the chest...
متن کاملApplication of subsecond rotation scan to helical CT for lung cancer screening.
PURPOSE To clarify whether the benefit of a reduced effective scan width obtained using a smaller pitch outweighs the disadvantage of increased noise in the application of a subsecond helical CT to mass screenings for lung cancer. MATERIALS AND METHODS Twenty-two helical CT scans of the lung were obtained in 11 healthy subjects using the following parameters: 1) scan 1 was performed at 120 kV...
