Introduction: Endometrial cancer is prevalent in the United States and has well documented disparities across race and ethnicity. The Society of Gynecologic Oncology’s (SGO) 2014 review on racial/ethnic disparities in gynecologic cancers, including endometrial, ended with a call to action to increase research on endometrial cancer disparities and to shift focus from identification of disparities to solutions. With a decade passed since the publication, it is unknown how the landscape of research on racial/ethnic disparities in endometrial cancer has changed. Objectives: A scoping review was conducted to identify the nature of research on racial/ethnic disparities in endometrial cancer since the publication of the SGO review in 2014, including summarizing the proportion of studies that focused on disparities across patient, provider and systemic spheres. Secondarily, to understand the proportion and nature of studies that proposed a solution to the identified racial/ethnic disparities. Methods: Scoping review was designed following the PRISM-SCa protocol. MEDLINE, EMBASE and Web of Science were searched to identify relevant studies. Inclusion criteria included: publication following the SGO statement, in English, published in the United States, on human subjects, primary study, specifically mentioned a racial or ethnic disparity in endometrial cancer. Reviews, meta- analyses, and opinion pieces were excluded. Relevant studies were coded for nature of disparity and solutions offered using a standardized data abstraction tool. Results: 182 studies were included, 141 (77.5%) focused on racial disparities, 34 (18.8%) on racial and ethnic, and 7 (3.8%) on ethnic, mainly Hispanic. Of those, 138 (75.8%) focused only on Black or African American disparities. When evaluating the level at which the disparity was identified, 116 (63.7%) were at the patient level, 25 (13.7%) at the provider level, 21 (11.5%) systemic, and 20 (11.5%) identified disparities on multiple levels. Half of the studies included offered solutions (91, 50.0%), however, the majority of the solutions suggested an increase in disparity research (32, 35.2%) and expanding clinical trials (15, 16.5%); many of these were included as further directions of the study itself. Other solutions included expanding access to health care (15, 16.5%), enhancing patient education (12, 13.2%), increasing patient participation in care (4, 4.4%), increasing diversity in the workforce (1, 1.1%), and other (12, 13.2%). Conclusions: Though much research on racial/ethnic disparities in endometrial cancer has been conducted since the SGO statement, many studies focused on patient-level factors instead of challenging provider/systemic level factors. When it came to a call to action, only half of the studies discussed a solution, the majority of which were included as future directions and suggested expansion of research. A small minority of articles outlined tangible solutions to the disparity discussed, leaving a continued need to shift research from identification of the disparity to creating solutions.
