Across TCGA pan-cancer cohorts, ERCC8 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated ERCC8 data layer compared with 24 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher ERCC8 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated ERCC8 expression acts as an unfavorable survival marker, although some lineages such as PDAC and HNSC show a favorable association.
LUAD, PDAC, and HNSC are the cancer types where ERCC8 mass-spec protein most reproducibly stratifies survival.
