Adenocarcinoma of the Esophagogastric Junction: Clinicopathological Characteristics
Kim Jie-Hyun

Abstract
The incidence of adenocarcinoma of the esophagogastric junction (AEG) is dramatically increasing in Western countries, while it is not increasing in Eastern countries. Siewert type I tumors are observed less frequently in Eastern countries in comparison to Western countries. On the other hand, other clinicopathological features of AEG, including age, male-to-female ratio, pathological grade, tumor progression, and prognosis, are similar in Western and Eastern countries. Many previous studies have demonstrated that the characteristics of type II tumors are more like those of type III tumors than those of type I tumors. Further investigation of the adequacy of esophageal classification for AEG of the seventh American Joint Committee on Cancer TNM classification should be necessary.
