Across TCGA pan-cancer cohorts, IL6 Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated IL6 data layer compared with 22 for mass-spec protein and 1 for mass-spec protein.
The strongest signal is observed in skin cutaneous melanoma (SKCM), where higher IL6 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated IL6 expression acts as an unfavorable survival marker.
SKCM, READ, and ESCA are the cancer types where IL6 Mutation most reproducibly stratifies survival.
