This study aims to establish a comprehensive database of Native American (NA) patients diagnosed with prostate cancer (PC) and Renal cell carcinoma (RCC) , focusing on an in-depth characterization of the genomic landscape. Archived tumor tissue collected at screening and peripheral blood samples obtained within the first year of enrollment will serve as the basis for comprehensive molecular analyses. Whole exome sequencing (WES) and whole transcriptome sequencing (RNA-seq) will be performed to characterize and delineate the genomic and transcriptomic landscape of the study cohorts. Oversight will be maintained by the Institutional Review Board and an independent Native American Advisory Board to ensure cultural appropriateness, transparency, and sustained community engagement throughout the research process. The overarching objective is to generate insights that will inform the development of personalized treatment strategies in the future.
