Eosinophilic esophagitis (EoE) is a chronic, immune-mediated inflammatory disorder of the esophagus that can lead to symptoms such as dysphagia and food impaction. In recent years, a potential association between EoE and esophageal cancer (EC) has been proposed, though evidence remains inconsistent and may be influenced by overlapping conditions like gastroesophageal reflux disease (GERD) and Barrett's esophagus (BE). The purpose of this study was to determine whether patients with EoE are at increased risk of developing esophageal cancer, and to clarify whether any observed risk is intrinsic to EoE or instead related to coexisting GERD or BE. The main research question was: Is eosinophilic esophagitis independently associated with an increased risk of esophageal cancer, or is this risk mediated by overlapping conditions such as GERD or Barrett's esophagus? To address this, we conducted a retrospective, multicenter cohort study using real-world data from TriNetX, a global federated health research network aggregating electronic medical records from approximately 100 million patients.
