Across TCGA pan-cancer cohorts, IL18BP mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated IL18BP data layer compared with 22 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher IL18BP mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated IL18BP expression acts as an unfavorable survival marker, although some lineages such as HNSC and PDAC show a favorable association.
HNSC, LUAD, and PDAC are the cancer types where IL18BP mass-spec protein most reproducibly stratifies survival.
