Colon cancer is staged using the American Joint Committee on Cancer (AJCC) tumor/node/metastasis (TNM) classification and staging system. In this system, stages are assigned on the basis of the characteristics of the primary tumor (T) and the extent of regional lymph node involvement (N) and distant metastasis (M). In addition, metastasis may be defined clinically or pathologically, on the basis of preoperative clinical assessment (c) or pathologic evaluation of metastatic tissue (p). [1, 2]
