Across TCGA pan-cancer cohorts, CCL20 mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated CCL20 data layer compared with 26 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher CCL20 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated CCL20 expression acts as an unfavorable survival marker, although some lineages such as PDAC show a favorable association.
LUAD and PDAC are the cancer types where CCL20 mass-spec protein most reproducibly stratifies survival.
