Abstract Introduction: Black men experience a significant burden and face greater hurdles in the prevention, detection, treatment, and survival of prostate cancer (CaP). To address barriers and systemic issues associated with CaP, we have established Community Living Lab (CoLLab) Learning Health Systems through a partnership with the American Legion Post (ALP) and Mayo Clinic. The focus is on providing comprehensive prostate health resources, education, amenities, and community health services (REACH). This initiative represents a proactive approach to addressing health disparities in prostate cancer prevention, detection, and treatment to improve CaP health equity for Black men. This study has three primary aims: (1) Co-develop a user-centric CoLLab Learning Health System with collaborating ALPs, (2) Evaluate the impact of the CoLLab Learning Health System using a pretest-posttest design, and (3) Explore the feasibility of replicating the CoLLab Learning Health System in Black communities nationally. Methods: Three ALPs in Northeast Florida are currently included in this pilot study. The study timeline spans 30 months, from October 2023 to March 2026. The target recruitment is 150 Black men aged 30 to 80 years. Community Health Workers (CHWs) are currently recruiting participants to complete the ALP Neighborhood assessment four times over 12 months to measure changes in CaP-related knowledge, attitudes, health beliefs, perceived control, intentions, and cues to action. Participants will be able to access prostate health REACH services at the designated ALPs through education, navigation, and support services. The program will be continuously evaluated for continuous improvement. The reach of the prostate health REACH services, including extent and patterns of use, demographics of participants reached, and successful navigation for social determinants of health (SDOH), clinical trials, and healthcare, will be evaluated. Additionally, participation in the Community Research Registry, indicating interest in being matched with clinical trials at Mayo Clinic, will be assessed. Results: To date, we have trained 10 CHWs for the study who will serve as community navigators to provide REACH services at their designated ALPs. We have had 49 Black men recruited into the study, and they have completed the baseline assessment at various events held at the ALPs. CaP survivors support group, led by ALP, has begun providing survivorship support services, including healthcare navigation, wellness programs, and grocery distribution to Black men and their households in the community surrounding the ALPs. Conclusion: The CoLLab initiative represents a proactive approach to addressing health disparities and improving outcomes for Black men in CaP prevention, detection, treatment, and survivorship. This study represents a crucial step towards eliminating CaP disparities experienced by Black men, contributing to improved health equity and outcomes in this population.

Abstract Introduction: In an effort to ensure an all-inclusive initiative that would close the disparity gap among the immigrant communities in Florida, we developed a pilot project under the Inclusive Cancer Care Research Equity (iCCaRE) for Black Men Consortium with generous support from the Mayo Clinic Comprehensive Cancer Center (MCCCC). The objective is to train cancer advocates to engage their communities and develop and implement cancer prevention and screening navigation programs. The central hypothesis for this program is that community-driven cancer advocacy will significantly improve cancer awareness, knowledge, prevention, risk reduction, screening uptake, and early detection among Black immigrants. Methods: We collaborated with immigrant communities’ leaders to brainstorm on the current state of healthcare access and disparities experienced by Black immigrants and to set program and research priorities through listening sessions. Cancer advocates were trained to engage their communities to (1) develop and implement cancer risk reduction and education programs using train-the-trainer approach, (2) mobilize the resources within the community for cancer health promotion, prevention, and screening strategies, (3) partner with key stakeholders to accomplish targeted objectives; (4) raise funds to support advocacy activities; and (5) develop and successfully organize community-centered programs. Results: We are currently working with 10 Black immigrant organizations, including immigrant churches across different ethnicities, including Nigeria, Ghana, Cameroon, Liberia, South Africa, Haiti, Jamaica, and across different cities in the United States. Eighteen community cancer advocates, including breast and prostate cancer survivors, caregivers, and community influencers, were trained to engage the immigrant communities in cancer risk reduction and research in Florida using multiple channels, including in-person community programs and online engagement approaches. We have engaged 720 immigrants in cancer risk reduction education and the need to participate in research during advocate-led in-person community outreaches. We currently have 26 immigrants who have volunteered in the Mayo Clinic Community Research Registry. The program is ongoing, and we anticipate that more than 750 will be engaged, and 100 will volunteer to be registered in the Mayo Clinic Community Research Registry. Conclusion: Advocate-led advocacy in immigrant communities will provide evidence for compelling arguments about the feasibility and availability of the Black immigrant population for robust and sustainable research and program engagements to eliminate disparity and advance cancer health equity.
