Across TCGA pan-cancer cohorts, VAMP8 mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated VAMP8 data layer compared with 28 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher VAMP8 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated VAMP8 expression acts as an unfavorable survival marker, although some lineages such as LUAD and HNSC show a favorable association.
PDAC, GBM, and LSCC are the cancer types where VAMP8 mass-spec protein most reproducibly stratifies survival.
