Cancer in adults with intellectual disability: a systematic review of prevalence and incidence

BACKGROUND: The epidemiology and pattern of cancer in people with an intellectual disability is poorly documented. Emerging evidence reports that a different profile and trajectory of cancer burden is experienced in this population. The prevalence and incidence of cancer in this group have not been systematically synthesised. This review will address a significant gap in the evidence base. METHODS: The Joanna Briggs Prevalence and Incidence methodology was used to guide the conduct of this review. Reporting the review adheres to the PRISMA checklist. Observational studies reporting prevalence and incidence of cancer and cancer subtypes in adults with intellectual disability were identified through searches of Embase, MEDLINE, CINAHL, PsycINFO, Web of Science, and grey literature from database inception dates to May…
