Across TCGA pan-cancer cohorts, ESAM mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated ESAM data layer compared with 24 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher ESAM mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated ESAM expression acts as an unfavorable survival marker, although some lineages such as CCRCC and LSCC show a favorable association.
CCRCC, PDAC, and LUAD are the cancer types where ESAM mass-spec protein most reproducibly stratifies survival.
