Across TCGA pan-cancer cohorts, GTSF1 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated GTSF1 data layer compared with 17 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher GTSF1 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated GTSF1 expression acts as an unfavorable survival marker, although some lineages such as LUAD and PDAC show a favorable association.
HNSC, LUAD, and PDAC are the cancer types where GTSF1 mass-spec protein most reproducibly stratifies survival.
