Across TCGA pan-cancer cohorts, ARID3B mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated ARID3B data layer compared with 21 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher ARID3B mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated ARID3B expression acts as an unfavorable survival marker, although some lineages such as LSCC and LUAD show a favorable association.
HNSC, LSCC, and LUAD are the cancer types where ARID3B mass-spec protein most reproducibly stratifies survival.
