Across TCGA pan-cancer cohorts, LACTB2 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated LACTB2 data layer compared with 23 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher LACTB2 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated LACTB2 expression acts as an unfavorable survival marker, although some lineages such as PDAC show a favorable association.
PDAC, CCRCC, and LSCC are the cancer types where LACTB2 mass-spec protein most reproducibly stratifies survival.
