Across TCGA pan-cancer cohorts, SELENOP mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated SELENOP data layer compared with 21 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher SELENOP mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated SELENOP expression acts as an unfavorable survival marker, although some lineages such as CCRCC and PDAC show a favorable association.
LUAD, CCRCC, and PDAC are the cancer types where SELENOP mass-spec protein most reproducibly stratifies survival.
