Background: The 2006 American Society of Clinical Oncology (ASCO) recommendation states that Carcinoembryonic Antigen (CEA) is checked before surgery to aid in staging or planning of action as well as in assessing the response to adjuvant chemotherapy. Chemotherapy in colorectal cancer can be performed as adjuvant, neoadjuvant, or palliative therapy. One type of chemotherapy in colorectal cancer patients is capecitabine. Capecitabine is a type of adjuvant chemotherapy with oral preparations that has advantages in terms of flexibility of use, is not invasive, and is less costly.
