Across TCGA pan-cancer cohorts, KDELR3 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated KDELR3 data layer compared with 26 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher KDELR3 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated KDELR3 expression acts as an unfavorable survival marker, although some lineages such as UCEC and PDAC show a favorable association.
LSCC, UCEC, and PDAC are the cancer types where KDELR3 mass-spec protein most reproducibly stratifies survival.
