Several organizations recommend (2) or suggest (3) that clinicians offer screening to persons who meet either the NLST criteria for lung cancer risk or modified versions of these criteria if comprehensive multidisciplinary coordinated care and follow-up similar to those provided to NLST participants are available. A major issue for practical and cost-effective implementation of low-dose CT screening for lung cancer is the definition of a positive scan.A positive low-dose CT scan, by definition, triggers diagnostic work-up.
