The objective of this review is to synthesize existing evidence on interventions addressing racial or ethnic disparities in cancer-related health care access and clinical outcomes. <\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p> A comprehensive search of Cochrane Library, Google Scholar, Ovid MEDLINE, Ovid Embase, PubMed, Scopus, and Web of Science Core Collection was conducted from database inception to February 23, 2023. Controlled vocabulary and keywords helped to identify studies on cancer-related disparities and interventions in adults age 18 years or older. Two reviewers followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis reporting guidelines. Study quality was assessed using the Joanna Briggs Institute Critical Appraisal Tool. <\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p> Of 7,526 screened studies, 34 met the inclusion criteria involving 24,134 participants. Most studies focused on breast cancer (n = 17) and Hispanic\/Latino populations (n = 10) and enrolled participants primarily from community-based sites (n = 19). Twenty-one studies examined patient-centered outcomes, such as health-related quality of life and psychological well-being, while 15 studies assessed process-of-care outcomes, such as timeliness of care. Most studies followed a community-based participatory research framework. Five patient-centered outcome studies reported a positive intervention effect, often combining cancer education with psychological well-being interventions. Among the 15 process-of-care outcome studies, nine reported positive effects, with the majority (n = 8) being navigation-based interventions. <\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p> This systematic review emphasizes the vital role of community partnerships in addressing racial and ethnic disparities in oncology care and highlights the need for standardized approaches in intervention research because of the heterogeneity of studied interventions. Furthermore, the prevailing emphasis on breast cancer and Hispanic populations indicates the need for future investigations into other priority demographic groups.
