Advanced adenomas are adenomas at a high risk of developing into cancer. They are defined by size and by histology. The definitions have been extrapolated from the Atkin study published by the group from St. Mark’s Hospital in 1992, which looked at metachronous symptomatic cancers presenting after removal of index adenomas during rigid proctoscopy [1]. This question discusses the suitability of the original criteria for defining advanced adenomas 33 years after their publication.

摘要

Advanced adenomas are adenomas at a high risk of developing into cancer. They are defined by size and by histology. The definitions have been extrapolated from the Atkin study published by the group from St. Mark’s Hospital in 1992, which looked at metachronous symptomatic cancers presenting after removal of index adenomas during rigid proctoscopy [1]. This question discusses the suitability of the original criteria for defining advanced adenomas 33 years after their publication.
