Globally, approximately 1.1 billion people smoke, and in the U.S, there are approximately 19 million heavy smokers, or those that smoke at least 1 pack per day. LDCT is a recommended method for screening lung cancer in high risk individuals, primarily heavy smokers. Published in June 2011 in New England Journal of Medicine, the landmark NCI-sponsored National Lung Screening Trial (NLST) reported a 20% relative reduction in mortality with LDCT screening of high risk individuals with a history of ≥30 pack-years and ≤15 years since they quit smoking, versus annual chest X-rays. In the NLST, 24.2% of subjects screened were deemed positive for lung cancer, and the majority of positive screens led to additional tests. When a positive screening result was found, 96.4% of the LDCT tests were deemed "false" positives. As a result, the cost of screening large numbers of high risk individuals, the potential harm associated with LDCT screening, and the high false positive rate with LDCT highlight the need for complementary biomarkers to improve diagnostic performance.
"Screening heavy smokers with Spiral CT scans saves many lives, but the cost-effectiveness of this approach has been questioned due to the high rate of false positives," stated Gabriele Cerrone, Founder and Executive Chairman of GENSIGNIA. "In combination with a Spiral CT, the MSC Lung Cancer assay significantly reduces the false positive rate, which can translate in substantial savings for the global healthcare system by avoiding the need for additional workups and scans required to confirm diagnosis."
