Esophageal cancer is a common cancer worldwide and has a poor prognosis. The incidence of esophageal squamous cell cancer has been decreasing, whereas the incidence of esophageal adenocarcinoma has been increasing rapidly, particularly in Western men. Squamous cell cancer continues to be the major type of esophageal cancer in Asia, and the main risk factors include tobacco smoking, alcohol cons...

The incidence of esophageal adenocarcinoma has markedly increased in the last few decades and Barrett's esophagus is regarded as the precursor lesion of this cancer. The aim of the study was to quantify the adenocarcinoma risk associated with nonsteroidal anti-inflammatory drug use and to determine at which stage chemoprevention with this drug is the most effective in esophageal inflammation - ...

The importance of genetic factors in the etiology of esophageal cancer is uncertain. We addressed the question of heredity in a population-based, nationwide case-control study conducted in Sweden during 1995 through 1997. The study involved 189 patients with esophageal adenocarcinoma, 262 with cardia adenocarcinoma, 167 with esophageal squamous cell carcinoma, and, for comparison, 820 control s...

Aspirin has been proposed in recent years as a candidate for chemoprevention of adenocarcinoma in patients with Barrett's esophagus. The aim of the present study was to evaluate the effect of acetylsalicylic acid (ASA) in an experimental model of esophageal adenocarcinoma. An animal model of gastroenteroesophageal reflux was established using Wistar rats undergoing esophagojejunostomy with gast...

Introduction. The objective of this study was to evaluate Ki-67 antigen expression in patients with Barrett's esophagus and esophageal adenocarcinoma and to assess its correlation with the metaplasia-esophageal adenocarcinoma progression. Methods. Using immunohistochemistry we evaluated the Ki-67 index in patients with Barrett's esophagus, esophageal adenocarcinoma, and controls. We included pa...

Background and study aims: Better endoscopic diagnosis in case of Barrett's esophagus is still needed. White globe appearance (WGA) is a novel endoscopic marker for gastric adenocarcinoma, with high sensitivity for differentiating between gastric cancer/high-grade dysplasia and other lesions. We report 2 cases of esophageal adenocarcinoma with WGA. In Case 1, esophagogastroduodenoscopy (EGD) re...

PURPOSE To examine the associations between area-level socioeconomic attributes and stage of esophageal adenocarcinoma diagnoses in 16 SEER cancer registries during 2000-2007. METHODS Odds ratios (OR) and 95% confidence intervals (CI) were calculated using multivariable logistic regression models to assess the relationship between distant-stage esophageal adenocarcinoma and individual, census...

OBJECTIVE Mortality due to esophageal adenocarcinoma has risen markedly, but the molecular mechanisms underlying this carcinogenesis are still incompletely understood. Findings from loss of heterozygosity (LOH) studies have suggested that the long arm of chromosome 4 might harbor tumor suppressor genes relevant to esophageal adenocarcinoma. METHODS We performed LOH analysis of 4q in esophagea...

BACKGROUND Cyclin E is a cell cycle regulator which is critical for driving G1/S transition. Abnormal levels of cyclin E have been found in many cancers. However, the level changes of cyclin E in esophageal adenocarcinoma and its precancerous lesion have not been well studied. Here, we focus on the gene amplification and expression of cyclin E in these lesions, and aim to ascertain the relation...

BACKGROUND The tissue specificity and robustness of miRNAs may aid risk prediction in individuals diagnosed with Barrett's esophagus. As an initial step, we assessed whether miRNAs can positively distinguish esophageal adenocarcinoma from the precursor metaplasia Barrett's esophagus. METHODS In a case-control study of 150 esophageal adenocarcinomas frequency matched to 148 Barrett's esophagus...
