Across TCGA pan-cancer cohorts, FGF18 Mutation is linked to patient survival in 2 of 34 cancer types, making it a survival-associated FGF18 data layer compared with 25 for mass-spec protein.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where higher FGF18 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated FGF18 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
LUSC and UCEC are the cancer types where FGF18 Mutation most reproducibly stratifies survival.
