What are the rates of progression of Barrett’s esophagus to cancer before and after ablation therapy?
Barrett’s esophagus may progress to more advanced forms of Barrett’s esophagus or esophageal adenocarcinoma. The rates of progression of Barrett’s esophagus to esophageal adenocarcinoma vary depending on the severity (or grade) of disease. Possible grades of Barrett’s esophagus include: non-dysplastic, low-grade dysplastic and high-grade dysplastic. The grade of a patient’s Barrett’s esophagus is determined by evaluation of biopsy specimens taken from the esophagus during an upper endoscopy exam.
