Across TCGA pan-cancer cohorts, PCF11 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated PCF11 data layer compared with 30 for mass-spec protein and 9 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher PCF11 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated PCF11 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and GBM show a favorable association.
CCRCC, HNSC, and GBM are the cancer types where PCF11 mass-spec protein most reproducibly stratifies survival.
