Yes: Chemotherapy regimens based on the drug Fluorouracil (5-fu) have been part of the treatment for high-risk stage ii or stage iii colon cancer. Many clinical trials have shown that these regimens improve overall survival primarily by reducing the high risk of recurrence within the first two years after surgery.
