Across TCGA pan-cancer cohorts, IFIT3 mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated IFIT3 data layer compared with 27 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in colon adenocarcinoma (COAD), where higher IFIT3 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated IFIT3 expression acts as an unfavorable survival marker, although some lineages such as LSCC show a favorable association.
COAD and LSCC are the cancer types where IFIT3 mass-spec protein most reproducibly stratifies survival.
