Across TCGA pan-cancer cohorts, ICE2 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated ICE2 data layer compared with 24 for mass-spec protein and 7 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher ICE2 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated ICE2 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
HNSC, UCEC, and CCRCC are the cancer types where ICE2 mass-spec protein most reproducibly stratifies survival.
