Across TCGA pan-cancer cohorts, CCN3 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated CCN3 data layer compared with 23 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher CCN3 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated CCN3 expression acts as an unfavorable survival marker.
LUAD, LSCC, and PDAC are the cancer types where CCN3 mass-spec protein most reproducibly stratifies survival.
