==Background== | |||
*[[Colorectal adenocarcinoma]] is defined by invasion into the submucosa. | |||
**This is different than elsewhere in the GI tract, where cancer is defined by invasion through the basement membrane, i.e. into the lamina propria. | |||
**Rationale: nasty (cancer-like) cells in lamina propria only do not have metastatic potential as there are no lymphatics in the colorectal lamina propria.<ref>{{Cite journal | last1 = Lewin | first1 = MR. | last2 = Fenton | first2 = H. | last3 = Burkart | first3 = AL. | last4 = Sheridan | first4 = T. | last5 = Abu-Alfa | first5 = AK. | last6 = Montgomery | first6 = EA. | title = Poorly differentiated colorectal carcinoma with invasion restricted to lamina propria (intramucosal carcinoma): a follow-up study of 15 cases. | journal = Am J Surg Pathol | volume = 31 | issue = 12 | pages = 1882-6 | month = Dec | year = 2007 | doi = 10.1097/PAS.0b013e318057fac2 | PMID = 18043043 }}</ref> | |||
