Across TCGA pan-cancer cohorts, EMB mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated EMB data layer compared with 25 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher EMB mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated EMB expression acts as an unfavorable survival marker, although some lineages such as HNSC show a favorable association.
LSCC, PDAC, and UCEC are the cancer types where EMB mass-spec protein most reproducibly stratifies survival.
