Across TCGA pan-cancer cohorts, OPRD1 mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated OPRD1 data layer compared with 21 for mass-spec protein and 7 for mutation status.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher OPRD1 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated OPRD1 expression acts as an unfavorable survival marker, although some lineages such as UCEC and GBM show a favorable association.
UCEC and GBM are the cancer types where OPRD1 mass-spec protein most reproducibly stratifies survival.
