Across TCGA pan-cancer cohorts, C5AR2 mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated C5AR2 data layer compared with 26 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher C5AR2 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated C5AR2 expression acts as an unfavorable survival marker.
PDAC are the cancer types where C5AR2 mass-spec protein most reproducibly stratifies survival.
