Across TCGA pan-cancer cohorts, AMY2B mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated AMY2B data layer compared with 28 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher AMY2B mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated AMY2B expression acts as an unfavorable survival marker.
PDAC are the cancer types where AMY2B mass-spec protein most reproducibly stratifies survival.
