Across TCGA pan-cancer cohorts, HR mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated HR data layer compared with 22 for mass-spec protein and 11 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher HR mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated HR expression acts as an unfavorable survival marker, although some lineages such as GBM show a favorable association.
GBM are the cancer types where HR mass-spec protein most reproducibly stratifies survival.
