Temporal Trends in Lung Cancer Cases Diagnosed at Early Stage

Has the percentage of lung cancer cases diagnosed at an early stage changed since lung cancer screening was recommended in 2013?In this descriptive surveillance study, 4 363 687 new lung cancer cases were reported in the US from 2003 to 2022. The percentage diagnosed at early stage increased slowly from 17.6% in 2003 to 20.2% in 2014, increased sharply from 21.4% in 2015 to 24.6% in 2016, then increased steadily to 30.1% in 2022.Since lung cancer screening was recommended in 2013, more people with lung cancer are being diagnosed early, when there are more treatment options.
