Colon Cancer Staging

There are two type of staging systems used for Colon cancer staging. The two are listed below,

Colon Cancer Staging - TNM Staging System (Tumor, Node, Metastisis)

  • Stage 0: Very early cancer on the innermost layer (more accurately considered a precursor to cancer)
  • Stage I: Tumor in the inner layers of the colon
  • Stage II: Tumor has spread through the muscle wall of the colon
  • Stage III: Tumor that has spread to the lymph nodes
  • Stage IV: Tumor that has spread to distant organs

Colon Cancer Staging - Modified Duke Staging System

Stage A The tumor penetrates into the mucosa of the bowel wall but no further.
Stage B B1: tumor penetrates into, but not through the muscularis propria (the muscular layer) of the bowel wall.

B2: tumor penetrates into and through the muscularis propria of the bowel wall.

Stage C C1: tumor penetrates into, but not through the muscularis propria of the bowel wall; there is pathologic evidence of colon cancer in the lymph nodes.

C2: tumor penetrates into and through the muscularis propria of the bowel wall; there is pathologic evidence of colon cancer in the lymph nodes.

Stage D The tumor, which has spread beyond the confines of the lymph nodes (to organs such as the liver, lung or bone).
