Potential Racial Disparities Using Current Lung Cancer Screening Guidelines

Rationale The current age threshold for lung cancer screening targets individuals beginning at age 55. These guidelines were developed based on results from the National Lung Cancer Screening Trial where only 4.4% of the enrollees were African American, when they represent 12.3% of US population. African Americans were also found to have higher incidence and younger onset of lung cancer. We hypothesized that implementation of screening at age 55 would not detect a substantial fraction of early onset lung cancer cases in African American population.
