Cancer inequalities experienced by people with disability: a systematic review protocol

IntroductionCancer is a leading cause of death and has a significant impact on individuals, families and society. Emerging evidence shows that people with disability face challenges in accessing services which could assist in early cancer diagnosis and optimal treatment, like cancer screening. Consequently, cancer patients with disabilities may present with later-stage disease, have reduced treatment options and experience lower survival rates compared with people without disability.This systematic review aims to summarise and evaluate the existing evidence on (a) inequalities in cancer survival and mortality between people with and without disability, (b) the inequalities in cancer screening and (c) stage at diagnosis that may contribute to the survival/mortality gap.Methods and analysisA literature search will be performed on MEDLINE, Embase, PsycInfo and Scopus up to May 2023. The review will include quantitative studies that reported inequalities in cancer survival and mortality, screening and stage at diagnosis between adults with and without disability. A summary of the characteristics and findings of the included studies will be provided. We will assess the quality of each study using the Risk Of Bias In Non-randomised Studies—of Exposure tool. Depending on the heterogeneity of studies, we will assess whether meta-analysis is appropriate.Ethics and disseminationEthics approval is not applicable for this study since no original data will be collected. The results will be disseminated through peer-reviewed publications and conference presentations.PROSPERO registration numberCRD42023427288.
