Adaptation of the socioecological model to address disparities in engagement of Black men in prostate cancer genetic testing.

BACKGROUND: Black men consistently have higher rates of prostate cancer (PCA)- related mortality. Advances in PCA treatment, screening, and hereditary cancer assessment center around germline testing (GT). Of concern is the significant under-engagement of Black males in PCA GT, limiting the benefit of precision therapy and tailored cancer screening despite longstanding awareness of these disparities. To address these critical disparities, the Socioecological Model (SEM) was employed to develop comprehensive recommendations to overcome barriers and implement equitable strategies to engage Black males in PCA GT. METHODS: Clinical/research experts, national organization leaders, and community stakeholders spanning multiple regions in US and Africa participated in developing a framework for equity in PCA GT grounded in the SEM. A novel mixed-methods approach was employed to generate key areas to be addressed and informed statements for consensus consideration utilizing the modified Delphi model. Statements achieving strong consensus (> =75% agreement) were included in final equity frameworks addressing clinical/community engagement and research engagement. RESULTS: All societal levels of the SEM (interpersonal, institutional, community, and policy/advocacy) must deliver information about PCA GT to Black males that address benefits/limitations, clinical impact, hereditary cancer implications, with acknowledgment of mistrust (mean scores [MS] 4.57-5.00). Interpersonal strategies for information delivery included engagement of family/friends/peers/Black role models to improve education/awareness and overcome mistrust (MS 4.65-5.00). Institutional strategies included diversifying clinical, research, and educational programs and integrating community liaisons into healthcare institutions (MS 4.57-5.00). Community strategies included partnerships with healthcare institutions and visibility of healthcare providers/researchers at community events (MS 4.65-4.91). Policy/advocacy included improving partnerships between advocacy and healthcare/community organizations while protecting patient benefits (MS 4.57-5.00). Media strategies were endorsed for the first time at every level (MS 4.56-5.00). CONCLUSION: The SEM-based equity frameworks proposed provide the first multidisciplinary strategies dedicated to increase engagement of Black males in PCA GT, which are critical to reduce disparities in PCA-mortality through informing tailored screening, targeted therapy, and cascade testing in families.

Engaging community members in cancer research: an assessment of an NCI-designated cancer center.

PURPOSE: Despite the importance of engaging community members in research, multiple barriers exist. We conducted a mixed-methods evaluation to understand the opportunities and challenges of engaging community members in basic, clinical, translational, and population science research. METHODS: We designed a survey and an interview guide based on the constructs of the Consolidated Framework for Implementation Research. Surveys were distributed electronically to all cancer center investigators and interviews were conducted virtually with a select group of basic, clinical, and population science investigators. Survey data (n = 77) were analyzed across all respondents using frequency counts and mean scores; bivariate analyses examined differences in responses by research program affiliation, gender, race, and faculty rank. Interviews (n = 16) were audio recorded, transcribed verbatim, and analyzed using a reflective thematic approach. RESULTS: There was strong agreement among investigators that "Community engagement in research will help the SKCC address cancer disparities in the catchment area" (M 4.2, SD 0.9) and less agreement with items such as "I know how to find and connect with community members who I can engage in my research" (M 2.5, SD 1.3). Investigators mentioned challenges in communicating complex science to a lay audience but were open to training and workshops to acquire skills needed to integrate community members into their research. CONCLUSION: Cancer centers should develop and promote training and collaborative opportunities for investigators and community members. Overcoming challenges will lead to more patient- and community-centered cancer research in the future.
