Across TCGA pan-cancer cohorts, HPSE mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated HPSE data layer compared with 20 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher HPSE mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated HPSE expression acts as an unfavorable survival marker, although some lineages such as LSCC show a favorable association.
PDAC, LSCC, and LUAD are the cancer types where HPSE mass-spec protein most reproducibly stratifies survival.
