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