Across TCGA pan-cancer cohorts, KCP mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated KCP data layer compared with 24 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher KCP mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated KCP expression acts as an unfavorable survival marker.
CCRCC, PDAC, and UCEC are the cancer types where KCP mass-spec protein most reproducibly stratifies survival.
