Across TCGA pan-cancer cohorts, IL1RN mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated IL1RN data layer compared with 24 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher IL1RN mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated IL1RN expression acts as an unfavorable survival marker, although some lineages such as HNSC and UCEC show a favorable association.
HNSC, UCEC, and CCRCC are the cancer types where IL1RN mass-spec protein most reproducibly stratifies survival.
