Across TCGA pan-cancer cohorts, TRIM28 mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated TRIM28 data layer compared with 25 for mass-spec protein and 7 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher TRIM28 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated TRIM28 expression acts as an unfavorable survival marker, although some lineages such as GBM and LUAD show a favorable association.
HNSC, GBM, and UCEC are the cancer types where TRIM28 mass-spec protein most reproducibly stratifies survival.
