Across TCGA pan-cancer cohorts, CD68 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated CD68 data layer compared with 22 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher CD68 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated CD68 expression acts as an unfavorable survival marker, although some lineages such as HNSC show a favorable association.
CCRCC, LSCC, and HNSC are the cancer types where CD68 mass-spec protein most reproducibly stratifies survival.
