NCIt 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).;
