Across TCGA pan-cancer cohorts, HRK mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated HRK data layer compared with 26 for mass-spec protein.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher HRK mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated HRK expression acts as an unfavorable survival marker, although some lineages such as LUAD show a favorable association.
HNSC, GBM, and LUAD are the cancer types where HRK mass-spec protein most reproducibly stratifies survival.
