Across TCGA pan-cancer cohorts, VTCN1 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated VTCN1 data layer compared with 23 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher VTCN1 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated VTCN1 expression acts as an unfavorable survival marker, although some lineages such as CCRCC show a favorable association.
PDAC, CCRCC, and HNSC are the cancer types where VTCN1 mass-spec protein most reproducibly stratifies survival.
