MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Low-dose computed tomography (LDCT) scans is the main method used for early lung cancer diagnosis. Early lung cancer diagnosis significantly reduces mortality. LDCT scans identify nodules in the lungs of 24% of the people in the high-risk population, but 96% of these nodules are benign. Currently there is no accurate way to discriminate benign from malignant nodules and hence all people with identified nodules are subjected to follow up screens or biopsies. This increases healthcare costs and creates more anxiety for these individuals. By analyzing a compendium of low-dose computed tomography scan data together with demographics and other clinical variables we were able to develop a predictor that offers a promising solution to this problem.
