Across TCGA pan-cancer cohorts, BAP1 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated BAP1 data layer compared with 27 for mass-spec protein and 8 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher BAP1 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated BAP1 expression acts as an unfavorable survival marker, although some lineages such as LSCC show a favorable association.
PDAC, LUAD, and CCRCC are the cancer types where BAP1 mass-spec protein most reproducibly stratifies survival.
