Across TCGA pan-cancer cohorts, CST8 mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated CST8 data layer compared with 15 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher CST8 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated CST8 expression acts as an unfavorable survival marker.
LSCC are the cancer types where CST8 mass-spec protein most reproducibly stratifies survival.
