Across TCGA pan-cancer cohorts, ARG1 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated ARG1 data layer compared with 16 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher ARG1 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated ARG1 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and UCEC show a favorable association.
CCRCC, LUAD, and PDAC are the cancer types where ARG1 mass-spec protein most reproducibly stratifies survival.
