Across TCGA pan-cancer cohorts, HROB mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated HROB data layer compared with 28 for mass-spec protein and 7 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher HROB mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated HROB expression acts as an unfavorable survival marker, although some lineages such as HNSC and LSCC show a favorable association.
PDAC, HNSC, and LSCC are the cancer types where HROB mass-spec protein most reproducibly stratifies survival.
