Across TCGA pan-cancer cohorts, ABCC2 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated ABCC2 data layer compared with 18 for mass-spec protein and 11 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher ABCC2 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated ABCC2 expression acts as an unfavorable survival marker.
CCRCC, LUAD, and PDAC are the cancer types where ABCC2 mass-spec protein most reproducibly stratifies survival.
