SCREENING TRIALS

For individuals at high risk for lung cancer, we make it our mission to spread awareness about the importance of lung cancer screening. Learn more about the major lung cancer screening trials here.

For individuals at a high-risk for lung cancer, lung cancer screening with low-dose computed tomography (CT) saves lives. 

​

Several randomized-controlled trials have found that low-dose CT scans detect most lung cancers at an early stage and significantly reduce lung cancer mortality.

Below are the summarized results of three prominent lung cancer screening trials.

U.S. NATIONAL LUNG SCREENING TRIAL

Summary: The goal of this study was to determine the effectiveness of using a low dose CT scan to detect lung cancer in patients considered high risk for lung cancer. Read the article here: Reduced Lung-Cancer Mortality with Low-Dose Computed Tomographic Screening | NEJM

The study looked at 2 groups: A group of patients who received annual low dose CT scans and a group of patients who received annual chest x-rays.

THE NELSON TRIAL

Summary: The goal of this study was to determine if lung-cancer mortality for high-risk persons was significantly lower among those who underwent volume CT screening than among those who underwent no screening.

Participants were randomly assigned to undergo CT screening at T0 (baseline), year 1, year 3, and year 5.5 or no screening.
