|Lung Cancer Screening|
A model projecting outcomes for nationwide low-dose CT screening for lung cancer estimated that gradual implementation of the program would detect roughly 54,900 more cases over five years in a high-risk Medicare population. The large majority of new cases would be early-stage disease.
The model assumes that over a five-year period, an additional 20 percent of high risk patients are offered screening each year. Investigators considered three different screening use scenarios for the implementation: an expected-use scenario based on historic experience with mammography (50 percent of patients offered screening undergo screening every year), a low-use scenario (25 percent), and a high-use scenario (75 percent).
