Across TCGA pan-cancer cohorts, NOTCH2 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated NOTCH2 data layer compared with 26 for mass-spec protein and 10 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher NOTCH2 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated NOTCH2 expression acts as an unfavorable survival marker, although some lineages such as HNSC show a favorable association.
CCRCC, COAD, and HNSC are the cancer types where NOTCH2 mass-spec protein most reproducibly stratifies survival.
