Across TCGA pan-cancer cohorts, PSMA6 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated PSMA6 data layer compared with 22 for mass-spec protein and 1 for mutation status.
The strongest signal is observed in colon adenocarcinoma (COAD), where higher PSMA6 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated PSMA6 expression acts as an unfavorable survival marker, although some lineages such as UCEC and LSCC show a favorable association.
COAD, LUAD, and UCEC are the cancer types where PSMA6 mass-spec protein most reproducibly stratifies survival.
