Abstract: In recent years, the incidence of adenocarcinoma of esophagogastric junction (AEG) has increased gradually. Due to the unique anatomical location and the different biological features from esophageal cancer and gastric cancer, AEG cannot be simply equated with esophageal cancer or gastric cancer, and the definition, classification and treatment methods of AEG are still controversial. As a result, the study of AEG is becoming increasingly important. Using bibliometrics, the authors search English literatures from the Web of Science Core Collection database from the establishment to December 31, 2022, with the keyword adenocarcinoma of esophagogastric junc-tion. To systematically review the international literatures on AEG, EndNote and Excel are used to manage literatures and perform statistical analysis, and VOSviewer and CiteSpace are used to analyze the social network, time series of countries, institutions, authors and keywords, the co-citation of authors and the citation bursts of keywords. The authors summarize the research status and hot trends in this field, hoping to provide reference for future research.
