Favorable effect of endoscopic reassessment of clinically staged T2 esophageal adenocarcinoma: a multicenter, prospective cohort study
Clinical tumor stage of esophageal adenocarcinoma is determined by endoscopic ultrasound and/or CT-scan. accuracy of these tools is low for stages T1 and T2, which may result in overtreatment. We aimed to assess the proportion of cT2 EAC downstaged to cT1 after endoscopic reassessment.ERA downstages about half of the cT2 tumors to cT1 suitable for ER. ERA has a substantial clinical impact on therapeutic management preventing overtreatment in 40% of patients.
