Analysis of the 30-Pack-Year Smoking Threshold in African Americans From an Underserved Lung Cancer Screening Program.

Purpose: African Americans were underrepresented in lung cancer screening (LCS) trials, despite having higher lung cancer incidence and worse outcomes compared with Caucasians. There is concern that the 30-pack-year threshold excludes some African Americans who may benefit from LCS.

Methods: LCS in an underserved health care system was reviewed.
