Across TCGA pan-cancer cohorts, PAEP mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated PAEP data layer compared with 28 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher PAEP mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated PAEP expression acts as an unfavorable survival marker.
LUAD, PDAC, and LSCC are the cancer types where PAEP mass-spec protein most reproducibly stratifies survival.
