Across TCGA pan-cancer cohorts, UGT1A8 mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated UGT1A8 data layer compared with 19 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher UGT1A8 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated UGT1A8 expression acts as an unfavorable survival marker, although some lineages such as HNSC show a favorable association.
HNSC are the cancer types where UGT1A8 mass-spec protein most reproducibly stratifies survival.
