Abstract

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.

Estimated New Cancer Cases and Cancer Deaths in the United States (2010).
A. Estimated New Cancer Cases in the United States. Lung cancer is the second most common cancer in the States being second only to prostate cancer in men and breast cancer in women (from reference 4).

B. Estimated New Cancer Deaths in the United States (2010). Lung cancer is the leading cause of cancer death in both men (29%) and women (26%). The statistical data shows that lung cancer causes the death of 157300 people every year in the United States (from reference 4).

Age-Standardized Death Rates of Cancers in the Korea (2011). Lung cancer becomes the major causes of cancer death from 1999. Lung cancer causes the largest number of cancer deaths in the Korea, accounts for more deaths than stomach cancer and hepatocellular carcinoma (from reference 5).
