About The Study: In this cohort study of Korean patients with lung cancer, international screening guidelines excluded 64.6% of patients, a substantial proportion of whom had no smoking history. Ineligible patients had lower mortality risk than screening-eligible patients. These findings suggest that population-specific strategies are needed to improve early detection among individuals not captured by current screening criteria.
