What are the specific stages of stomach cancer?

Staging stomach cancer involves discovering how many layers of the stomach the cancer has invaded. The stomach has five layers:
  • Inner layer: lining of the stomach
  • Submucosa: support tissue for inner layer
  • Muscle layer: muscles of the stomach
  • Subserosa: support tissue for the outer layer
  • Outer layer: outer lining, also called serosa
The stages of stomach cancer are as follows:

Stage 0. The tumor is found only in the inner layer of the stomach. Stage 0 is also called carcinoma in situ.

Stage I. One of the following:
  • Tumor has only invaded submucosa, and cancer cells may have spread to up to six lymph nodes.
  • Tumor has invaded muscle layer or subserosa. Cancer cells have not spread to lymph nodes.
Stage II. One of the following:
  •  Tumor has only invaded submucosa. Cancer cells have spread to seven to 15 lymph nodes.
  • Tumor has invaded muscle layer or subserosa. Cancer cells have spread to one to six lymph nodes.
  • Tumor has penetrated outer layer of stomach with no spread.
Stage III. One of the following:
  • Tumor has invaded muscle layer or subserosa. Cancer has spread to seven to 15 lymph nodes.
  • Tumor has penetrated the outer layer. Cancer has spread to one to six lymph nodes.
  • Tumor has spread to nearby organs. Cancer has not spread to lymph nodes or distant organs.
Stage IV. One of the following:
  • Cancer has spread to more than 15 lymph nodes.
  • Tumor has spread to nearby organs and at least one lymph node.
