Systematic review of clinical practice guidelines for colorectal and anal cancer: the extent of recommendations for managing long-term symptoms and functional impairments.

Purpose: Due to increasing numbers of colorectal and anal cancer survivors, more individuals are living with long-term symptoms after treatment. A systematic review was undertaken to assess the extent to which practice guidelines for colorectal and anal cancer provide recommendations for managing long-term symptoms and functioning impairments.

Methods: Four electronic databases and websites of 30 international cancer societies were searched for clinical practice guidelines, consensus statements, or best practice recommendations for colorectal or anal cancer. Quality of included guidelines was evaluated with the Appraisal of Guidelines for Research & Evaluation II tool. Results were narratively summarized.

Results: We included 51 guidelines or consensus statements. Recommendations for managing long-term symptoms or functioning impairments were reported in 13 guidelines (25.4%). All 13 recommend a healthy lifestyle, diet, body weight, and physical activity. The ASCO Colorectal Cancer Survivorship Care Guideline is the most comprehensive, including interventions targeting sexual and bowel function to pain and cognitive issues, and also highlights limited evidence for informing management strategies. Other guidelines recommend treating incontinence, chronic diarrhea, and distress, and stress the need for greater awareness for sexual dysfunction, survivorship clinics, and referrals to specific supportive care interventions.

Conclusions: Few clinical practice guidelines include recommendations for managing long-term symptoms and functioning impairments. It is unclear if this is due to limited evidence or absence of management strategies and interventions. Clear recommendations for managing long-term symptoms and functioning to help health professionals in supporting colorectal and anal cancer survivors are needed.
