Across TCGA pan-cancer cohorts, DKK2 mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated DKK2 data layer compared with 23 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher DKK2 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated DKK2 expression acts as an unfavorable survival marker.
LUAD and LSCC are the cancer types where DKK2 mass-spec protein most reproducibly stratifies survival.
