Evaluation for local failure by 18F-FDG PET/CT in comparison with CT findings after stereotactic body radiotherapy (SBRT) for localized non-small-cell lung cancer

Abstract: Purpose: Stereotactic body radiotherapy (SBRT) is the standard care for medically inoperable early non-small-cell lung cancer (NSCLC). However, it can be difficult to differentiate local recurrence from non-recurrence radiation-induced lung opacity. We retrospectively assessed 18F-FDG PET/CT to detect local recurrence after SBRT for NSCLC.Methods: Between 2005 and 2011, 273 NSCLCs in...
