Intersectionality in cancer care: A systematic review of current research and future directions.

ABSTRACT

OBJECTIVES: The objective of the current review was to synthesize the literature on intersectionality relative to disparities across the cancer care continuum. A model to support future intersectional cancer research was proposed. METHODS: Web-based discovery services and discipline-specific databases were queried for both peer-reviewed and gray literature. Study screening and data extraction were facilitated through the Covidence software platform. RESULTS: Among 497 screened studies, 28 met study inclusion criteria. Most articles were peer-reviewed empirical studies (n = 22) that focused on pre-diagnosis/screening (n = 19) and included marginalized racial/ethnic (n = 22) identities. Pre-cancer diagnosis, sexual orientation and race influenced women's screening and vaccine behaviors. Sexual minority women, particularly individuals of color, were less likely to engage in cancer prevention behaviors prior to diagnosis. Race and socioeconomic status (SES) were important factors in patient care/survivorship with worse outcomes among non-white women of low SES. Emergent themes in qualitative results emphasized the importance of patient intersectional identities, as well as feelings of marginalization, fears of discrimination, and general discomfort with providers as barriers to seeking cancer care. CONCLUSIONS: Patients with intersectional identities often experience barriers to cancer care that adversely impact screening, diagnosis, treatment, as well as survivorship. The use of an "intersectional lens" as a future clinical and research framework will facilitate a more multidimensional and holistic approach to the care of cancer patients.
