Core Tip

Core tip: The present study first clarified the performance of 18-fluoro-2-deoxyglucose positron emission tomography (FDG-PET) for esophageal cancer screening by adopting an appropriate study method. A large number of asymptomatic screened individuals who underwent both FDG-PET and esophagogastroduodenoscopy were included in the study, and the performance of FDG-PET was assessed by comparing the results of FDG-PET and esophagogastroduodenoscopy, considering the latter as the reference. As a result, the low screen sensitivity (3.6%) and positive predictive value (2.0%) of FDG-PET for esophageal cancer were clearly shown. Based on the results, FDG-PET is considered to be difficult to use as a screening modality for esophageal cancer.
