Colon cancer is a leading cause of mortality in Appalachian Kentucky. Studies suggest that the microbiome may influence cancer outcomes. We investigate differential gene expression, the tumor microbiome, and the association between the two as potential drivers of disparities in colon cancer outcomes. ⋯ This is the first report of the distinct tumor microbiome in Appalachian Kentucky and its impact on survival. Further studies are needed to better characterize the unique tumor and gut microbiome of Appalachian patients with colon cancer.
