Abstract B059: Advancing equitable access to prostate cancer genomic testing through community-informed and culturally tailored strategies

Abstract Background: Genomic testing is a cornerstone of precision oncology, yet certain communities remain underrepresented in its uptake. Limited genetic literacy, medical mistrust, and access barriers persist, particularly among populations at higher risk for prostate cancer. Community-driven approaches are urgently needed to promote equitable engagement in precision cancer care. Methods: To explore community perspectives and inform intervention development, a 31-member Community Advisory Board (CAB) was convened cross Duval County (FL), Maricopa County (AZ), and Olmsted County (MN). CAB members, representing racially, ethnically, and geographically diverse stakeholders, participated in small-group discussions (n=5) using a mixed-methods framework. Qualitative and quantitative data were collected to assess knowledge, perceptions, and barriers to genetic testing for prostate cancer. Results: Three overarching themes emerged: (1) limited awareness of the existence and purpose of genetic testing for prostate cancer; (2) the need for culturally tailored messages and trusted community messengers to raise awareness; and (3) persistent structural and informational barriers to accessing care. Participants emphasized the role of non-clinical, community-trusted individuals in delivering messages that resonate and build trust within their communities. Conclusions: Findings highlight the critical importance of community-engaged, culturally responsive strategies to advance genomic literacy and reduce disparities in prostate cancer care. This formative work will directly inform the design of a targeted, community-based educational intervention to improve equitable access to genomic testing among underserved populations.
