“…From initial diagnosis through definitive treatment, pathological assessment of a resected colorectal cancer is still considered the most accurate method of assessing the tumorrelated features that determine postoperative outcome. Different clinico-pathological prognostic factors have been proposed: location of the tumor [21,22,26,27,35,38] , depth of tumor invasion [32,37,40] , tumor stage [32,47] , differentiation of tumor [20,21,48] , surgical procedure [15,25] , pathological type [25,48] , tumor size [21,[48][49][50] , lymph node metastasis [21,51,52] and distant metastasis [15,25,48] . The site of the tumor has been investigated as a possible prognostic factor.…”
