    Treatment decisions should be made with reference to the TNM classification [1] rather than to the older Dukes or the Modified Astler-Coller classification schema.The American Joint Committee on Cancer (AJCC) and a National Cancer Institute–sponsored panel recommended that at least 12 lymph nodes be examined in patients with colon and rectal cancer to confirm the absence of nodal involvement by tumor.[2,3,4] This recommendation takes into consideration that the number of lymph nodes examined is a reflection of the aggressiveness of lymphovascular mesenteric dissection at the time of surgical resection and the pathologic identification of nodes in the specimen. Retrospective studies demonstrated that the number of lymph nodes examined in colon and rectal surgery may be associated with patient outcome.[5,6,7,8]AJCC Stage Groupings and TNM DefinitionsThe AJCC has designated staging by TNM classification to define
