Across TCGA pan-cancer cohorts, EEFSEC mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated EEFSEC data layer compared with 25 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher EEFSEC mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated EEFSEC expression acts as an unfavorable survival marker, although some lineages such as CCRCC show a favorable association.
PDAC, CCRCC, and COAD are the cancer types where EEFSEC mass-spec protein most reproducibly stratifies survival.
