Across TCGA pan-cancer cohorts, GGT5 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated GGT5 data layer compared with 21 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher GGT5 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated GGT5 expression acts as an unfavorable survival marker, although some lineages such as LUAD and CCRCC show a favorable association.
LSCC, LUAD, and CCRCC are the cancer types where GGT5 mass-spec protein most reproducibly stratifies survival.
