Abstract Introduction: Tribal Nations across the Southwest have striking disparities in cancer incidence and mortality. Compounded by disproportionately low rates of cancer screening and limited access to healthcare, Native Americans are more often diagnosed at later stages of disease and have the poorest outcomes in all types of cancer when compared to any other racial and ethnic group in the United States. At the University of New Mexico Comprehensive Cancer Center, the Participant Engagement Cancer Genomic Sequencing (PE-CGS) Center is developing culturally appropriate materials and strategies to enhance the engagement and recruitment of Native Americans into genomic research. This effort aims to determine participant knowledges, attitudes, cultural beliefs, and communication preferences regarding clinical genomics testing. Ultimately, targeting improvement of cancer outcomes in Southwestern Tribal communities. Cultural adaptations are crucial with regards to biospecimen collection, storage, and usage, due to historical mistrust of research among Native communities. (i.e., Havasupai Tribe v. the Arizona Board of Regents). A Tribal Advisory Committee, consisting of Tribal leaders, Native physicians, and patient advocates oversee all aspects of the research study. The goal is to identify appropriate optimized health literacy strategies for engaging Native peoples in cancer genomic research. Methods: The team conducted semi-structured discussions with participants to understand their perspectives on motivations to join, cultural safety components, and effectiveness of engagement strategies. With participant consent, the discussions were recorded and transcribed. Analysis included the transcripts and notes taken by the interviewer and followed Grounded Theory principles. All transcripts and notes followed line-by-line analysis by three of the authors (JS, JR and TG) who met regularly to identify and discuss emergent themes. Results: As of May 31, 2024, the PE-CGS study has enrolled 112 participants and completed 39 discussions. Participants emphasized altruistic motives tied to family and community, echoing traditional values, in their decision to participate in the study. This notion emerged during interactions with Native team members, where comfort stemmed from shared experiences (healthcare system, barriers), use of Native language, and adherence to Native social norms. Additional considerations included present autonomy throughout various stages of the study (sample use, data sharing, discussions). Return of genetic testing results improved understanding of treatment options, hereditary risk, and health literacy. Conclusion: Feedback highlights the importance of aligning cultural beliefs with Western medicine through a strengths-based approach. The findings will inform improvements in respectful engagement, communication, information exchange, and recruitment processes with Native American cancer patients and cancer survivors to genomic testing studies.
