Survival Rates for Colon Cancer Based on Stage
The stage of
colon cancer plays a role in survival rates. Based on historical data:
- 39 percent of colon cancer cases are diagnosed while the disease is still confined to the primary site (localized stage)
- 37 percent of cases are diagnosed after the cancer has spread to regional lymph nodes or directly beyond the primary site
- 19 percent of colon cancer cases are diagnosed after the disease has already metastasized (distant stage)
- 5 percent of cases had staging information that was unknown.
The corresponding five-year relative colon cancer survival rates were:
- 90.4 percent for localized
- 68.1 percent for regional
- 9.8 percent for distant
- 34.6 percent for unstaged.
