Supportive care interventions for managing gastrointestinal symptoms following treatment for colorectal cancer: a systematic review.

Introduction: Colorectal cancer (CRC) is prevalent in the developed world, with unhealthy lifestyles and diet contributing to rising incidence. Advances in effective screening, diagnosis, and treatments have led to improved survival rates, but CRC survivors suffer poorer long-term gastrointestinal consequences than the general population. However, the current state of clinical practice around provision of health services and treatment options remains unclear.
Purpose: We aimed to identify what supportive care interventions are available to manage gastrointestinal (GI) symptoms for CRC survivors.
Methods: We searched Cochrane Central Register of Controlled Trials, Embase, MEDLINE, PsycINFO, and CINAHL from 2000 to April 2022 for resources, services, programs, or interventions to address GI symptoms and functional outcomes in CRC. We extracted information about characteristics of supportive care interventions, the study design, and sample characteristics from included studies, and performed a narrative synthesis RESULTS: Of 3807 papers retrieved, seven met the eligibility criteria. Types of interventions for managing or improving GI symptoms included two rehabilitation, one exercise, one educational, one dietary, and one pharmacological. Pelvic floor muscle exercise may help to resolve GI symptoms more quickly in the post-operative recovery phase. Survivors may also benefit from rehabilitation programs through improved self-management strategies, especially administered soon after completing primary treatment.
Conclusions/implications for Cancer Survivors: Despite a high prevalence and burden of GI symptoms post-treatment, there is limited evidence for supportive care interventions to help manage or alleviate these symptoms. More, large-scale randomized controlled trials are needed to identify effective interventions for managing GI symptoms that occur post-treatment.
