Abstrakt:	Importance: Racial and ethnic disparities in clinical trial enrollment are unjust and hinder development of new cancer treatments. Objective: To examine the association of race and ethnicity with clinical trial enrollment among women with endometrial, ovarian, or cervical cancer. Design, Setting, and Participants: This retrospective cohort study used data from the National Cancer Database, a hospital-based cancer registry, and the Surveillance, Epidemiology, and End Results Program (SEER), a population-based cancer registry. Population-based race and ethnicity-specific proportions for each cancer site were derived from SEER. Participants included women with an endometrial, ovarian, or cervical cancer diagnosed from 2004 to 2019. Analyses were performed from February 2 to June 14, 2023. Exposure: Race and ethnicity were categorized as American Indian/Alaska Native, Asian, Black, Hispanic (any race), Native Hawaiian/Pacific Islander, White, and other (not defined in the National Cancer Database). Main Outcomes and Measures: The primary outcomes were the odds of clinical trial enrollment and representation in clinical trials compared with the US population. Multivariable-adjusted logistic regression was used to estimate odds ratios (ORs) and 95% CIs for associations of race and ethnicity with clinical trial enrollment within the National Cancer Database sample. Participation-to-prevalence ratios (PPRs) according to diagnosis period (2004-2011 vs 2012-2019) were calculated by dividing the race and ethnicity-specific percentage of clinical trial participants in the study sample by the percentage of racial and ethnic groups in SEER. Results: Among 562 592 patients with gynecologic cancer (mean [SD] age at diagnosis, 62.9 [11.3] years), 1903 were American Indian/Alaska Native, 18 680 were Asian, 56 421 were Black, 38 145 were Hispanic, 1453 were Native Hawaiian/Pacific Islander, 442 869 were White, and 3121 were other race and ethnicity. Only 548 (<1%) were enrolled in clinical trials. Compared with White women, clinical trial enrollment was lower for Asian (OR, 0.44; 95% CI, 0.25-0.78), Black (OR, 0.70; 95% CI, 0.50-0.99), and Hispanic (OR, 0.53; 95% CI, 0.33-0.83) women. Compared with the US population, White women were adequately or overrepresented for all cancer types (PPRs ≥1.1), Black women were adequately or overrepresented for endometrial and cervical cancers (PPRs ≥1.1) but underrepresented for ovarian cancer (PPR ≤0.6), and Asian and Hispanic women were underrepresented among all 3 cancer types (PPRs ≤0.6). Conclusions and Relevance: In this cohort of patients with gynecologic cancer, clinical trial enrollment was lower among certain minoritized racial and ethnic groups. Continued efforts are needed to address disparate clinical trial enrollment among underrepresented groups.
