Across TCGA pan-cancer cohorts, CDH4 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated CDH4 data layer compared with 20 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher CDH4 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated CDH4 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
GBM, UCEC, and CCRCC are the cancer types where CDH4 mass-spec protein most reproducibly stratifies survival.
