Abstract A083: Diversifying breast cancer clinical trial accrual: An approach to recruitment at a Comprehensive Cancer Center

Background: Breast cancer (BC) prevention clinical trials (CTs) play a vital role in the progress of preventative measures and treatments for all races and ethnicities. However, Northern European whites (NE/W) continue to be disproportionally enrolled (e.g., 93.5% were non-Hispanic white in the STAR trial), while minorities such as Asians, blacks, Latinas, and Native Americans (NA) lag in participation. Current studies suggest that minorities are not approached as frequently as NE/W; however, they are just as willing to participate. Here we present a successful recruitment strategy to improving minority accrual in CTs at a Comprehensive Cancer Center located in Duarte, CA. Method: Results from community focus groups suggested the need to mentor local youth who strive to pursue a career in the medical field. Consequently, from February 2016 to July 2018, four bilingual, bicultural clinical research assistants (CRAs) were recruited from the catchment area of City of Hope (CoH). The CRAs, in collaboration with seven surgeons, two radiologists, and one medical oncologist, led the recruitment for three nontherapeutic BC prevention CTs at CoH. Results: All four CRAs were 1) first-generation American, 2) fluent in Spanish or Vietnamese, 3) born and raised in Southern California, and 4) pre-health. Of the 3,148 patients who were screened, 398 were eligible for enrollment, 369 consented, and 58 declined. Primary languages and races/ethnicities of those who declined include the following: 7% Armenian, 9% Chinese, 78% English, 2% Thai, and 5% Spanish; 28% Asian, 3% black, 28% Latina, 2% NA, and 67% white (22% NE, 17% Middle Eastern/North African). Demographics of the consenting population include the following: primary language - >1% Armenian, 4% Chinese, 89% English, >1% Korean, and 7% Spanish; race/ethnicity - 14% Asian, 6% black, 30% Latina, 5% NA, and 75% white (40% NE). Of the white population (n = 277), 11% were Middle Eastern/North African, 53% NE, and 36% Latina. Accrual surpassed both the CoH catchment area (11.3% Asian, 8% black, 24% Hispanic, 1% NA, and 32% NE/W) and the CoH interventional/nontherapeutic CT population (10% Asian/Pacific Islander, 4% black, 21% Hispanic, >1% NA, and 55% NE/W). Conclusion: Contrary to current accrual of CTs, here we show that minorities can have a large representation in CT accrual, as long as they are provided the opportunity. Accrual of Asians, Latinas, and NAs exceeded the catchment area and accrual of other CoH CTs. Interestingly, Chinese-speaking women comprised the highest declination group of the non-English speakers, and Asians and Latinas declined the most outside of non-whites. Cultural competency and bilingualism appear to be characteristics of a CRA that may help in accruing minority women into CTs. Our findings suggest that they are just as willing to participate, and the first step is to simply ask. Citation Format: Tanya A. Chavez, Christine Thai, Angelica Sanchez, Laura L.
