Executive Summary of the ARS Appropriate Use Criteria for Treatment of Anal Cancer

Abstract Purpose The American Radium Society Appropriate Use Criteria (ARS AUC) presented in this manuscript are evidence-based guidelines for curative- intent treatment of non-metastatic anal squamous cell cancer that are developed by a multidisciplinary expert panel. Methods Guideline development and systematic review using PRISMA methodology include an extensive analysis of current medical literature from peer-reviewed journals and application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures. In those instances where evidence is not definitive, expert opinion may be used to recommend imaging or treatment. Results Evidence-based guidelines are presented about the evaluation and treatment of anal cancer in various clinical scenarios that are derived from supporting literature and multidisciplinary consensus. Conclusions These guidelines are intended for the use of all practitioners and patients who desire information about the management of anal cancer covered in these guidelines.
