• In the past few decades, the incidence of esophageal adenocarcinoma has increased by six-fold in western countries, as the proton pump inhibitor targeting the gastric acid reflux has failed to control the disease. It is currently suggested that deoxycholic acid reflux leads to esophageal adenocarcinoma. As an inflammation-related cancer, the formation and progression of esophageal adenocarcinoma are closely related to the concentration of reactive oxygen species (ROS). Meanwhile, the critical developmental stage of esophageal adenocarcinoma involves characteristic pathological changes in which the distal esophageal squamous epithelial cells are replaced by intestinal columnar epithelial cells, suggesting the involvement of cancer stem cells. Thus, esophageal adenocarcinoma is a good model to study the interplay between ROS and stem cells in cancer. Until now, some important questions related to ROS in esophageal adenocarcinoma remain unanswered. For example, the molecular mechanism by which deoxycholic acid induces malignant transformation in esophageal adenocarcinoma remains unclear. In addition, whether ROS are involved in the induction of cancer stem cell formation by chemotherapeutic drugs and deoxycholic acid stimulation in esophageal adenocarcinoma remains to be further explored. This review summarizes current research progress on ROS and stemness activity, regulation of ROS by stanniocalcin-1 (STC1)/uncoupling protein 2 (UCP2), and inspiration for ROS in esophageal adenocarcinoma to guide further research and provide insight into the clinical treatment of esophageal adenocarcinoma.
