The Benchmark Study

Low-dose CT scans find lung cancer earlier

The National Lung Cancer Screening Trial (NLST), an eight-year national benchmark study released in 2010 and conducted by the American College of Radiology Imaging Network and the National Cancer Institute, showed:

  • 20% reduction in lung cancer mortality when it was detected by a low-dose CT scan versus a chest x-ray.
  • 40% of the cancers detected were found at an early and treatable stage.

The trial involved approximately 53,000 people ages 55 to 74 who had smoked at least one pack a day for 30 years or two packs a day for 15 years. Ex-smokers who had the above smoking history but had quit within the previous 15 years were also included in the group.

NCH takes a proactive approach

In response to this game-changing study, NCH was among the first hospitals in the Chicago area to launch an Early Lung Cancer Screening program in February 2011 for those at high risk for lung cancer. The NCH Lung Cancer Screening program follows the protocols of the National Lung Screening Trial and the NCCN (National Comprehensive Cancer Network) Guidelines for Lung Cancer Screening. More information on the NCCN guidelines can be found at

Don't wait. The time to know is now.

Catch cancer early, when it's most treatable. For questions about eligibility or to request a screening, call Juli Aistars, RN, APN, AOCN, TTS, Lung Nurse Navigator at 847-618-6572.
