*The retroperitoneal margin in right hemicolectomies should be treated like the radial margin in total mesorectal excisions; it should be inked.<ref>URL: [http://www.cancercare.on.ca/common/pages/UserFile.aspx?fileId=13954 http://www.cancercare.on.ca/common/pages/UserFile.aspx?fileId=13954].

*‡ Usually submitted completely and [[en face]]; if the margin is close (<2 cm) [[on edge margin|on edge]] is typically preferred.
*† Recommended minimum number of lymph nodes is 12.<ref name=pmid25234197>{{Cite journal  | last1 = Ihnát | first1 = P. | last2 = Delongová | first2 = P. | last3 = Horáček | first3 = J. | last4 = Ihnát Rudinská | first4 = L. | last5 = Vávra | first5 = P. | last6 = Zonča | first6 = P. | title = The Impact of Standard Protocol Implementation on the Quality of Colorectal Cancer Pathology Reporting. | journal = World J Surg | volume =  | issue =  | pages =  | month = Sep | year = 2014 | doi = 10.1007/s00268-014-2796-4 | PMID = 25234197 }}</ref>
