Is any lung cancer screening protocol applicable?
O. C. Enrizo, T. Baykaner and M. J. Janicek Boston University Medical Center, Boston, MA; Boston University, Boston, MA Abstract 1597 Background: Incidental finding of pulmonary nodules on CT is frequent and application of cancer screening derived follow up (f/u) algorithms could produce multiple repeated scans with low yield, high cumulative cost and radiation burden. Rationale of current standard recommendations was tested with respect to the size and number of nodules, age, prior cancer history in population of adults over age of 20 subjected to CTPA for chest pain. Methods: The frequency of incidental finding of pulmonary nodule was reviewed in 1434 CTPA done at BU over 1 year (2006) with benefit of 3 year f/u. Clinicians adherence to radiologist’s recommendation of f/u at 3, 6, and 12 months depending on cancer risk and dominant nodule size, and diagnostic yield of f/u studies were reviewed. Results: 43 patients (pts) with history of cancer were followed on specific protocols. In
