FUT8 and neoplasm: By stratifying patients on the basis of the p53 status in the IHC cohort, we found differential prognostic effect of FUT8 protein expression according to the p53 status, demonstrating that high FUT8 protein expression was significantly associated with better DFS only among patients with p53-negative tumor (Log-rank; P = 0.0076, Fig 3C), but not among patients with p53-positive tumor (Log-rank; P = 0.7779, Fig 3E).
