The increasing incidence of esophageal adenocarcinoma (EAC) is mirrored by the increasing prevalence of Barrett esophagus, a precursor lesion resulting in a large number of individuals "at risk" for this lethal malignancy. Among patients with Barrett esophagus, only about 0.3% annually will develop EAC. Because large numbers of patients are followed in endoscopic surveillance, there is a need f...

BACKGROUND Esophageal adenocarcinoma develops through a multistage process which is characterized histopathologically by progression from Barrett's intestinal metaplasia to Barrett's esophagus with dysplasia and ultimately to adenocarcinoma. The genetic basis of this process is increasingly well understood, but no studies have examined the role of the transcription factor c-myb in this disease....

Metastasis of breast cancer to the esophagus has been reported but is rare. It is often difficult to diagnose metastases of breast cancer to the esophagus because they are often located in the submucosa and covered with normal mucosa. Although several methods have been reported in order to obtain specimens for pathological diagnosis, the adverse effects including bleeding and perforation were c...

Adenocarcinomas of the esophagus and gastric cardia have increased in incidence over the past 10-15 years in Western countries. The cause for this increase in incidence is still unknown. Our study was designed to investigate potential risk factors for adenocarcinomas of the esophagus and gastric cardia and to compare the risk profiles of a group of patients with this cancer with those having di...

CONTEXT Gastroesophageal reflux disease (GERD) is a risk factor for adenocarcinoma of the esophagus, a rare cancer whose incidence is increasing. Adenocarcinoma may develop from Barrett esophagus, a metaplastic change of the esophageal epithelium from squamous to intestinalized columnar mucosa, which is associated with chronic reflux. Some have recommended that patients with chronic reflux symp...

Barrett’s esophagus is a well-recognized precursor of esophageal adenocarcinoma. Surveillance of Barrett’s esophagus patients is recommended to detect high-grade dysplasia (HGD) or early cancer. Because of wide variation in the published cancer incidence in Barrett’s esophagus, the authors undertook a systematic review and meta-analysis of cancer and HGD incidence in Barrett’s esophagus.
