Across TCGA pan-cancer cohorts, CTSC mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated CTSC data layer compared with 22 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in colon adenocarcinoma (COAD), where higher CTSC mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated CTSC expression acts as an unfavorable survival marker.
COAD, GBM, and LUAD are the cancer types where CTSC mass-spec protein most reproducibly stratifies survival.
