Abstract

Gastric cancer (GC) is third leading cause of cancer-related death. Only 28.3% of new GC cases survive more than 5 years. Although incidence has declined in the United States, an increase is estimated for 2016. Risk factors include sex (risk is higher in men), Helicobacter pylori infection, heredity, and lifestyle. GC is usually diagnosed between the ages of 60-80 years. Prognosis of GC is largely dependent on the tumor stage at diagnosis and classification as intestinal or diffuse type; diffuse-type GC has worse prognosis. Chemoprevention has been shown to decrease risk, but is currently not used clinically.

Keywords: Atrophic gastritis; Dysplasia; Gastric cancer; Helicobacter pylori; Intestinal metaplasia.

Figure 2. The precancerous cascade
Prolonged gastric inflammation resulting from chronic H. pylori infection causes epithelial damage that leads to gastric atrophy, characterized by loss of parietal cells and chief cells and glandular atrophy. The gastric epithelium is then replaced by intestinal metaplasia, followed by foci of low-grade dysplasia, which can later develop to high-grade dysplasia that can later become adenocarcinomas.
