Across TCGA pan-cancer cohorts, CBX2 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated CBX2 data layer compared with 31 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher CBX2 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated CBX2 expression acts as an unfavorable survival marker, although some lineages such as PDAC and LSCC show a favorable association.
PDAC, HNSC, and LSCC are the cancer types where CBX2 mass-spec protein most reproducibly stratifies survival.
