食管癌中多见为鳞癌,而腺癌较少。近几年来发现食管癌中腺癌比率明显增加,而鳞癌降低。大多数食管腺癌患者见于Barrett食管。本文探讨食管和食管胃连接处腺癌发病率是否比以前增高,及其与Barrett食管间的联系。材料和方法:检查了1974～1989年Olmsted县居民中诊断为食管、食管胃连接处和胃癌者的病电,腺癌或鳞癌系根据复查原内镜、手术或尸检材料的显微镜玻片而作出诊断。原保存的手术标本再作组织切片,以寻
In esophageal cancer, squamous cell carcinoma is more common than adenocarcinoma. In recent years, it has been found that the rate of adenocarcinoma in esophageal cancer is significantly increased while squamous cell carcinoma is reduced. Most patients with esophageal adenocarcinoma are found in Barrett’s esophagus. This article examines whether the incidence of adenocarcinoma of the esophagus and esophagogastric junction is higher than before, and its association with Barrett’s esophagus. MATERIALS AND METHODS: We examined the electrical status of patients diagnosed with esophageal, esophageal and gastric junctions, and gastric cancer in Olmsted County residents from 1974 to 1989. Microscopic slides for reexamination of the original endoscopic, surgical or autopsy material were performed on adenocarcinoma or squamous cell carcinoma. Make a diagnosis. The original preserved surgical specimens were again sectioned to find
