Chest Ct Findings Among Adult Survivors Of Childhood And Young Adult Cancer With A History Of Chest Radiation.

103Background: While survivors of childhood and young adult cancer with a history of radiation therapy (RT) to the chest are known to be at increased risk for lung cancer, whether a CT-based lung cancer screening program is appropriate for this population is unknown. We sought to describe CT findings in a clinic-based population of childhood and young adult cancer survivors. Methods: We performed a detailed review of all diagnostic chest CT scans performed among patients seen in the Adult Long-Term Follow-Up Program at Memorial Sloan Kettering between August 2005 and May 2016.
