AB  - Introduction There is increasing attention on the cancer burden for adults with intellectual and developmental disabilities (IDD). Emerging evidence suggests there are differences in cancer experiences and outcomes for individuals living with IDD, from risk through survivorship. These differences may be attributed to features of the IDD, such as cognitive deficits and communication, as well as social determinants of health-like lower education levels and ableism. However, there is no comprehensive overview of the literature quantifying these potential disparities and describing the influencing factors. In this paper, we describe a scoping review protocol to systematically review published literature on cancer for adults with IDD. The purpose of this review is to identify differences in cancer risk, stage at diagnosis, treatment and survival along the cancer continuum for adults with IDD and outline potential contributing factors creating these disparities.Methods and analysis We will follow Arksey and O’Malley’s expanded framework for scoping reviews to conduct this review. We will systematically search electronic databases for peer-reviewed, published journal articles to identify appropriate studies in collaboration with a health science librarian. Two reviewers will independently review titles and abstracts followed by a full-text review to determine whether it meets inclusion criteria. A data chart for collecting and sorting information will be developed in consultation with the team. Results will be collated and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews: PRISMA-Scoping Reviews. Extracted information will be summarised quantitatively and qualitatively to meet review objectives.Ethics and dissemination This scoping review will employ a methodology to identify literature related to cancer outcomes and experiences for adults with IDD. Results will be disseminated to relevant stakeholders who care for and support individuals with IDD at local, provincial and national levels and through publishing findings. By highlighting the disparities in the cancer system and gaps in the research, this scoping review can provide direction for future action.
