Prognostic relevance of gastric cancer staging by endoscopic ultrasound

Background Recent trials and guidelines have established the use of neoadjuvant chemotherapy for resectable UICC stage II to IV gastric cancers. In this setting, preoperative staging is pivotal for correct patient selection. This cohort study was designed to assess the accuracy of endoscopic ultrasound (EUS) and the ability to select correctly patients for neoadjuvant chemotherapy on the basis of survival outcome.
