Influence of Surveillance PET/CT on Detection of Early Recurrence After Definitive Radiation in Stage III Non-small-cell Lung Cancer

摘要

To determine the optimal surveillance approach in the setting of locally-advanced nonesmall-cell lung cancer (NSCLC) treated with definitive radiation, we compared 2 commonly used strategies, positron emission tomography (PET)/computed tomography (CT)-based and CT-based. There were no differences in baseline clinical or treatment characteristics or any of the survival outcomes examined between the 2 groups. These results suggest that routine PET/CT imaging after definitive radiation treatment for locally-advanced NSCLC confers no benefit in early detection of recurrence.
