Across TCGA pan-cancer cohorts, EFR3A mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated EFR3A data layer compared with 22 for mass-spec protein and 7 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher EFR3A mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated EFR3A expression acts as an unfavorable survival marker, although some lineages such as CCRCC and HNSC show a favorable association.
PDAC, LSCC, and CCRCC are the cancer types where EFR3A mass-spec protein most reproducibly stratifies survival.
