A new study indicates that both high-grade abnormal cellular changes (dysplasia) and esophageal adenocarcinoma (a form of cancer) have increased in the last 25 years among people with a digestive condition known as Barrett’s esophagus. The study report, Increasing prevalence of high-grade dysplasia and adenocarcinoma on index endoscopy in Barrett’s esophagus over the past 2 decades, is published in the ...

Evolution describes how all living forms cope with challenges in their environment, as they struggle to persevere against formidable odds. Mutation and selective pressure — cornerstones of Darwin’s theory — are the means by which organisms gain an advantageous foothold or pass into oblivion. In a new study, researchers at ASU’s Biodesign Institute led an international team to explore how ...

Investigators at Case Western Reserve University School of Medicine and University Hospitals Cleveland Medical Center have developed a simple, swallowable test for early detection of Barrett’s esophagus that offers promise for preventing deaths from esophageal adenocarcinoma. Barrett’s esophagus (BE) is the precursor lesion of esophageal adenocarcinoma (EAC), a highly lethal cancer with more than 80 percent mortality at five years. ...
