Colorectal cancer (CRC) is the second most common cause of malignant deaths in industrialized countries, and it is known to be major cause of cancer morbidity and mortality [1, 2]. The 5-year survival rate for CRC can be as high as 90%, if the cancer is detected at an early stage, but it is estimated to be less than 10% if a metastasis occurs .
