Across TCGA pan-cancer cohorts, CXCL5 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated CXCL5 data layer compared with 27 for mass-spec protein and 1 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher CXCL5 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated CXCL5 expression acts as an unfavorable survival marker, although some lineages such as PDAC and LSCC show a favorable association.
PDAC, LSCC, and UCEC are the cancer types where CXCL5 mass-spec protein most reproducibly stratifies survival.
