Across TCGA pan-cancer cohorts, INTS9 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated INTS9 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 INTS9 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated INTS9 expression acts as an unfavorable survival marker, although some lineages such as LUAD and CCRCC show a favorable association.
HNSC, PDAC, and LUAD are the cancer types where INTS9 mass-spec protein most reproducibly stratifies survival.
