    Stage III gastric cancer is divided into stage IIIA, stage IIIB, and stage IIIC, depending on where the cancer has spread.

      • the serosa (outermost) layer of the stomach wall and is found in 1 or 2 lymph nodes near the tumor; or
      • the subserosa (layer of tissue next to the serosa) of the stomach wall and is found in 3 to 6 lymph nodes near the tumor; or
      • the muscle layer of the stomach wall and is found in 7 or more lymph nodes near the tumor.
    • Stage IIIB: Cancer has spread to:
      • nearby organs such as the spleen, transverse colon, liver, diaphragm, pancreas, kidney, adrenal gland, or small intestine, and may be found in 1 or 2 lymph nodes near the tumor; or
      • the serosa (outermost layer) of the stomach wall and is found in 3 to 6 lymph nodes near the tumor; or
      • the subserosa (layer of tissue next to the serosa) of the stomach wall and is found in 7 or more lymph nodes near the tumor.
    • Stage IIIC: Cancer has spread to:
      • nearby organs such as the spleen, transverse colon, liver, diaphragm, pancreas, kidney, adrenal gland, or small intestine, and may be found in 3 or more lymph nodes near the tumor; or
      • the serosa (outermost layer) of the stomach wall and is found in 7 or more lymph nodes near the tumor.
