KRAS and adenoma: Our findings align with those of a similar study, which demonstrated that Fusobacterium, Parvimonas, and Prevotella (Prevotella 9 in our case) are more enriched in intratumoral tissues compared to adenomas, with associations noted between KRAS mutations (p < 0.001) and microsatellite instability (p < 0.001) in these samples (16).
