As compared with grade 1 well-differentiated adenocarcinomas, grade 3 poorly-differentiated cancers have been shown to be associated with adverse outcomes.

Ruiz-Tovar 1J. Endoscopic resection by polypectomy has been shown to be sufficient for management of certain polyps containing cancer; however, it is important to keep in mind that polypectomy does not remove the lymph node drainage basin and may be an inadequate resection for some adenocarcinoma containing polyps that have specific histologic features.
