Across TCGA pan-cancer cohorts, MGST1 mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated MGST1 data layer compared with 25 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher MGST1 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated MGST1 expression acts as an unfavorable survival marker, although some lineages such as LUAD and LSCC show a favorable association.
CCRCC, HNSC, and PDAC are the cancer types where MGST1 mass-spec protein most reproducibly stratifies survival.
