Scientists have found a 20 percent reduction in deaths from lung cancer among current or former heavy smokers who were screened with low-dose helical computed tomography (CT) versus those screened by chest X-ray. This finding provides a more extensive analysis of the data originally reported in November 2010 while providing additional data to the public and research community without barriers to access.

Lung Cancer Screening Using Helical CT vs. Chest X-ray Reduces Deaths among Current and Former Heavy Smokers
November 4, 2010, 11:00AM
a study sponsored by the National Cancer Institute (NCI) has determined that low-dose helical computed tomography (CT) scans can reduce lung cancer mortality for current and former heavy smokers. In the nation-wide study, which included over 53,000 participants, researchers found 20 percent fewer lung cancer deaths among those who were screened with low-dose helical CT (also known as spiral CT) compared with those who were screened with chest X-rays. In addition, deaths from all-causes (including lung cancer) were seven percent lower in those who received the low-dose helical CT scans.

In September 2002, the National Cancer Institute (NCI) launched the largest lung cancer screening study ever undertaken. Called the National Lung Screening Trial (NLST), the study is seeking 50,000 current and former smokers to determine if screening people with either spiral computerized tomography (CT) or chest X-ray before they have symptoms can reduce deaths from lung cancer.
BenchMarks talked with the directors of NLST to get an overview of the study and what can be learned from it.
