Across TCGA pan-cancer cohorts, EDN3 mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated EDN3 data layer compared with 29 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher EDN3 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated EDN3 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
UCEC and PDAC are the cancer types where EDN3 mass-spec protein most reproducibly stratifies survival.
