Across TCGA pan-cancer cohorts, STAT5A mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated STAT5A data layer compared with 25 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher STAT5A mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated STAT5A expression acts as an unfavorable survival marker, although some lineages such as LUAD and PDAC show a favorable association.
LUAD, PDAC, and HNSC are the cancer types where STAT5A mass-spec protein most reproducibly stratifies survival.
