Brief 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.

Outcome Measures

Primary Outcomes (2)

  • Risk of mortality at 1 year, estimated using a survival curve

    This outcome corresponds to the 1 year mortality rates after diagnosis of adenocarcinoma of the anus.

    Year1

  • Risk of mortality at 5 years, estimated using a survival curve

    This outcome corresponds to the 5 year mortality rates after diagnosis of adenocarcinoma of the anus.

    Year5

Secondary Outcomes (5)

  • Describe the various anatomical, etiological and histological forms

    Year5

  • Adaptaion of the therapeutic management according to the clinical and histological form

    Year5

  • Describe their therapeutic management

    Year5

  • Compare prognosis by clinical and histological form

    Year5

  • Search for prognostic factors of severity in all forms

    Year5
