What is stomach adenocarcinoma?

Stomach cancer, also called gastric cancer, forms in tissues lining the stomach. In 2010, 21,000 Americans were estimated to have been diagnosed and 10,570 were expected to have died from stomach cancer.1  Stomach cancer is more common in men and most people diagnosed are over 70 years old. About 95 percent of all gastric cancers are adenocarcinomas, the type of cancer being studied by TCGA. About 80 percent of people with stomach cancer are diagnosed with advanced cancer. As a result, fewer than 15 percent of these people will survive longer than five years after their diagnosis because this cancer tends to quickly spread to other parts of the body.

What types of discoveries about stomach adenocarcinoma do The Cancer Genome Atlas (TCGA) researchers hope to make?

  • Determine whether stomach adenocarcinomas can be divided into subtypes according to differences in gene changes
  • Establish whether certain gene changes are linked to infection with H. pylori (the bacteria that causes stomach ulcers)
  • Identify differences in gene changes between early and late stage stomach tumors
