Nutritional self‐management in colorectal cancer patients and survivors: A scoping review

Abstract

AbstractAimColorectal cancer (CRC) patients need CRC‐specific dietary guidance, but often lack access to adequate nutritional information and support. This scoping review identified study interventions, online resources, which have been produced to support nutritional care self‐management for CRC patients from diagnosis, through treatment and into survivorship and guidelines to underpin these.MethodsThe review was carried out in accordance with the JBI method for Scoping Reviews. Study interventions, online resources that support the self‐management of nutrition and diet in CRC patients were eligible for inclusion, along with CRC‐specific guidelines. Searches up to February 2023, were carried out via MEDLINE, CINAHL, PsycInfo, Embase, and Web of Science for published literature and ProQuest Dissertations, Theses Global, TRIP Medical Database, and Google search engines for grey literature. Two reviewers independently screened titles and abstracts, and relevant full texts for inclusion. Data were analysed descriptively.ResultsEight study interventions, 74 online resources and three guidelines specifically aimed at CRC patients were included in the review. Study interventions were heterogenous with respect to duration, whether it was personalized, who supported delivery and which guidelines underpinned the intervention. Three study interventions resulted in improved quality of life and one lengthened survival. A total of 36 (48.6%) online resources were produced by UK charity organizations. Most of the included information was for patients after completing treatment. Specific advice for patients with a stoma was lacking. Some of the online resources provided conflicting advice. The three guidelines explained how dietary adjustments can help address symptoms related to cancer or treatment and two provided more specific guidance on making dietary changes, with specific examples of how to tailor dietary advice to patient needs.ConclusionThis scoping review of study interventions, online resources, and guidelines highlighted the need for reliable, detailed, and personalized information to help CRC patients to self‐manage their nutritional care.
