OBJECTIVE: Predicting the invasion depth of superficial esophageal squamous cell carcinoma (SESCC) is important when selecting among therapeutic strategies. The aim of this study was to compare magnifying endoscopy with narrow-band imaging (ME-NBI) with endoscopic ultrasonography (EUS) for predicting the depth of tumor invasion in patients with SESCC. METHODS: This study enrolled 51 patients with SESCC (52 SESCC lesions) who underwent both ME-NBI and EUS at Pusan National University Hospital during 2010-2013. We reviewed the patients' medical records and compared ME-NBI and EUS findings with histopathological results according to clinicopathological factors. RESULTS: A total of 46 lesions in 45 patients were included in the final analysis. ME-NBI and EUS had overall accuracies of 76.1% and 84.8%, respectively, in distinguishing mucosal from non-mucosal cancers. There were no differences between ME-NBI and EUS in terms of sensitivities and specificities in distinguishing mucosal from non-mucosal cancers (p = 0.500 and p = 0.688, respectively). When both ME-NBI and EUS suggested a mucosal depth of lesion invasion, the frequency of mucosal cancer in the final histopathology was 94%. However, if either ME-NBI or EUS suggested a non-mucosal depth of invasion, the frequency of mucosal cancer was only 21%. CONCLUSION: ME-NBI and EUS are accurate predictors of SESCC invasion depth. If both methods suggest a mucosal depth of lesion invasion, the accuracy of the prediction is increased. Therefore, when possible, it would be better to evaluate the invasion depth of SESCC using both ME-NBI and EUS before deciding to perform endoscopic resection.
