Colon cancer is a common and deadly disease. Surgical resection is the primary treatment modality for colon cancer. For patients who have undergone potentially curative resection, disease recurrence is thought to derive from clinically occult micrometastases that are present at the time of surgery. The goal of postoperative or adjuvant therapy is to eradicate these micrometastases, thereby decreasing the likelihood of relapse, and increasing the cure rate. Although, adjuvant therapy decreased the rate of recurrence and death, it was not used largely for old patients. The recent regimes include systemic adjuvant therapy and almost adjuvant therapy lasted for 6 months or more, the common side-effects often occur in gastrointestinal tract and hematopoietic system. Radiotherapy was considered depending on each case. Local adjuvant treatment was concerned when liver metastasis was removed
