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