Clinical Trial Summary

Adenocarcinoma of the anus is rare. It concerns less than 10% of anal cancers and its incidence is less than 0.2/100 000 inhabitants. Its management is not consensual and is most often derived by analogy with that of adenocarcinoma of the lower rectum. This is due to the rarity but also to the diversity of anatomical (anal margin, anal canal, lower rectum), etiological (primary glandular tumors or secondary to anal fistula, primary distant tumor and/or Crohn's disease) and histological forms (mucinous, intestinal, glandular adenocarcinomas and primary or secondary Paget's disease). Most of the literature consists of small case series and simple clinical cases in which the prognosis of these subforms has not been studied.
