Spatial metabolic trajectories in the “normal‐to‐normal adjacent tissue (NAT)‐to‐tumor” transition, and temporal metabolic trajectories in the “colitis‐to‐dysplasia‐to‐carcinoma” transition are identified through K‐means clustering of 74 spatially and 77 temporally differential metabolites, respectively. Here, BRD2 is linked to colitis.
