Colon Cancer Prognosis (Expectations)
If the patient's colon cancer does not come back (recur) within 5 years, it is considered cured. This is because colon cancer rarely comes back after 5 years. Stage I, II, and III cancers are considered potentially curable. In most cases, stage IV cancer is not curable.
Stage I has a 90% 5-year survival. Stage II has a 75-85% 5-year survival, and Stage III a 40-60% 5-year survival. These numbers take into account that for stage III patients (and in some studies, stage II patients) chemotherapy improves the chance of 5-year survival.
Patients with stage IV disease rarely live beyond five years and the median survival (meaning half the patients live longer, and half shorter) with treatment is between 1 and 2 years.
