Across TCGA pan-cancer cohorts, HMGA1 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated HMGA1 data layer compared with 31 for mass-spec protein.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher HMGA1 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated HMGA1 expression acts as an unfavorable survival marker, although some lineages such as OV and CCRCC show a favorable association.
PDAC, OV, and HNSC are the cancer types where HMGA1 mass-spec protein most reproducibly stratifies survival.
