Across TCGA pan-cancer cohorts, CXCL16 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated CXCL16 data layer compared with 26 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher CXCL16 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated CXCL16 expression acts as an unfavorable survival marker.
PDAC, LUAD, and CCRCC are the cancer types where CXCL16 mass-spec protein most reproducibly stratifies survival.
