Across TCGA pan-cancer cohorts, IL12B mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated IL12B data layer compared with 22 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher IL12B mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated IL12B expression acts as an unfavorable survival marker, although some lineages such as PDAC show a favorable association.
GBM and PDAC are the cancer types where IL12B mass-spec protein most reproducibly stratifies survival.
