Across TCGA pan-cancer cohorts, PRSS22 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated PRSS22 data layer compared with 20 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher PRSS22 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated PRSS22 expression acts as an unfavorable survival marker, although some lineages such as LSCC and HNSC show a favorable association.
PDAC, LSCC, and LUAD are the cancer types where PRSS22 mass-spec protein most reproducibly stratifies survival.
