title: Restaging after radiotherapy and chemotherapy: value of endoscopic ultrasonography.
abstract: The outcome in gastroenterological tumors is determined by many factors. Prospective studies are required to prove the clinical value of endoscopic ultrasonography. Endoscopic ultrasonography as a staging tool may have only indirect influence on the outcome by providing potentially better selection criteria for the application of different treatments that are stage dependent.
