Introduction: Little data is available surrounding societal recommendations regarding extra-colonic malignancy in patients with inflammatory bowel disease (IBD). As a result, we systematically analyzed these international guidelines to assess their overall quality as well as their adherence to standards for high-quality practice guidelines.

Methods: A systematic search was performed in multiple databases to identify all guidelines pertaining to extra-colonic malignancy in IBD in April 2020. All guidelines were reviewed for conflicts of interest (COI)/funding, recommendation quality and strength, external document review, use of patient representation, and plans for update-as per Institute of Medicine standards. In addition, recommendations were compared between guidelines/societies. Statistical analysis was conducted using R.

Results: A total of 11 recommendations on extra-colonic malignancy in IBD were put forth by 5 guidelines/societies. Zero percent of recommendations were found to be based on high-quality evidence, 36.4% of recommendations on moderate-quality evidence, and 63.6% of recommendations on low-quality evidence. 9.1% were strong recommendations, 0% were weak/conditional recommendations, and 90.9% of recommendations did not provide a strength. No guideline included patient representation or had plans for future update of their recommendations.

Conclusion: There is a consistent lack of high-quality recommendations for extra-colonic malignancy in IBD across different societal guidelines. The need for high-quality studies to improve the strength of recommendations is eminent, as this will ultimately lead to high-quality patient care.
