Korean Society of Thoracic Radiology Guideline for Lung Cancer Screening with Low-Dose CT

The National Lung Screening Trial (NLST), a nation-wide randomized controlled trial involving more than 50,000 current and former heavy smokers ages 55 to 74, compared the effects of two screening procedures (low-dose helical CT and standard chest radiography) on lung cancer mortality and found 20 percent fewer lung cancer deaths among trial participants screened with low-dose CT. Korean Society of Thoracic Radiology (KSTR) planned to establish an effective guideline for lung cancer screening with low-dose CT to improve health of Korean people and to reduce harms from misuse of lung cancer screening with low-dose CT. KSTR guideline for lung cancer screening with low-dose CT established based on objective medical evidences obtained by NLST.
