Associated Genetic Biomarkers

Overview

NCI Definition: An adenocarcinoma arising from the stomach glandular epithelium. Gastric adenocarcinoma is primarily a disease of older individuals. It most commonly develops after a long period of atrophic gastritis and is strongly associated with Helicobacter pylori infection. The lack of early symptoms often delays the diagnosis of gastric cancer. The majority of patients present with advanced tumors which have poor rates of curability. Microscopically, two important histologic types of gastric adenocarcinoma are recognized: the intestinal and diffuse type. The overall prognosis of gastric adenocarcinomas is poor, even in patients who receive a "curative" resection (adapted from Sternberg's Surgical Pathology, 3rd ed., 1999). [1]

Gastric adenocarcinomas most frequently harbor alterations in TP53, ARID1A, CDH1, KRAS, and ERBB2 [2].

Most Commonly Altered Genes in Gastric Adenocarcinoma

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, ARID1A Mutation, and CDH1 Mutation are the most common alterations in gastric adenocarcinoma [2].
