Across TCGA pan-cancer cohorts, CD27 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated CD27 data layer compared with 25 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher CD27 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated CD27 expression acts as an unfavorable survival marker, although some lineages such as LUAD and HNSC show a favorable association.
LUAD, HNSC, and PDAC are the cancer types where CD27 mass-spec protein most reproducibly stratifies survival.
