Increasing interest in identifying an effective strategy for decreasing the burden of esophageal adenocarcinoma (EAC) has been fuelled by the rising EAC rates worldwide, the morbidity associated with esophagectomy, and the development of endoscopic methods for curing early-stage EAC. In the face of this enthusiasm, however, we should be cautious about continuing our current evidence-free approach to screening and one with unclear benefits and unclear costs to the community. The literature is increasingly recognizing that the value of traditional endoscopy for screening and surveillance of Barrett esophagus may be more limited than initially believed. A better understanding of the risk factors for Barrett esophagus and progression to dysplasia and a more individualized risk calculation will be useful in defining populations to consider for Barrett screening. The development of novel, nonendoscopic screening techniques and of less expensive endoscopic techniques holds promise for a cost-effective screening and surveillance method to curtail the increasing rates of EAC.
