Abstract

We report a comparison between upper gastrointestinal fiberscopy (GIF) and ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) for screening of upper gastrointestinal double cancer in patients with oral cancer.
Between September 2006 and August 2009, 133 patients with oral cancer underwent GIF and FDG-PET/CT before treatment. Five patients (3.8%) had synchronous double cancer in the esophagus or stomach using GIF. There were early-stage cancers in all cases. However, FDG-PET/CT could detect double cancer (esophageal cancer) in only one patient, and the sensitivity and specificity were 20% and 100%, respectively. This study proved the usefulness and necessity of GIF for screening in the upper gastrointestinal regions before treatment in patients with oral cancer.
