The Veterans Health Affairs (VHA) lung cancer screening (LCS) demonstration project identified a much higher false-positive rate following initial low-dose computed tomographic screening than did the National Lung Screening Trial (58.2% vs 26.3%).1,2 Most false-positive results (nodules not confirmed to be lung cancer [LC] after follow-up) resulted in repeated imaging, but 2.0% of people screened also required nonbeneficial downstream diagnostic evaluation to determine these nodules were not cancer.2 We sought to put these findings into context by examining how this high false-positive rate influences the harm-to-benefit ratio for higher- vs lower-risk patients.
