Overview

NCI Definition: A malignant tumor with glandular differentiation arising predominantly from Barrett mucosa in the lower third of the esophagus. Rare examples of esophageal adenocarcinoma deriving from ectopic gastric mucosa in the upper esophagus have also been reported. Grossly, esophageal adenocarcinomas are similar to esophageal squamous cell carcinomas. Microscopically, adenocarcinomas arising in the setting of Barrett esophagus are typically papillary and/or tubular. The prognosis is poor. [1]

Esophageal adenocarcinomas most frequently harbor alterations in TP53, CDKN2A, ERBB2, KRAS, and ARID1A [2].

Most Commonly Altered Genes in Esophageal Adenocarcinoma

TP53 Mutation, TP53 Missense, TP53 c.217-c.1178 Missense, TP53 Exon 5 Mutation, and TP53 Exon 8 Mutation are the most common alterations in esophageal adenocarcinoma [2].
