Across TCGA pan-cancer cohorts, SPEM1 Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated SPEM1 data layer compared with 14 for mass-spec protein.
The strongest signal is observed in prostate adenocarcinoma (PRAD), where higher SPEM1 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated SPEM1 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
PRAD, SKCM, and UCEC are the cancer types where SPEM1 Mutation most reproducibly stratifies survival.
