Across TCGA pan-cancer cohorts, ALB mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated ALB data layer compared with 22 for mass-spec protein and 8 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher ALB mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated ALB expression acts as an unfavorable survival marker, although some lineages such as HNSC and CCRCC show a favorable association.
PDAC, HNSC, and CCRCC are the cancer types where ALB mass-spec protein most reproducibly stratifies survival.
