Across TCGA pan-cancer cohorts, CASTOR2 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated CASTOR2 data layer compared with 29 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher CASTOR2 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated CASTOR2 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and GBM show a favorable association.
CCRCC, GBM, and LSCC are the cancer types where CASTOR2 mass-spec protein most reproducibly stratifies survival.
