Across TCGA pan-cancer cohorts, KDM4B mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated KDM4B data layer compared with 24 for mass-spec protein and 8 for mutation status.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher KDM4B mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated KDM4B expression acts as an unfavorable survival marker, although some lineages such as UCEC and HNSC show a favorable association.
UCEC, PDAC, and HNSC are the cancer types where KDM4B mass-spec protein most reproducibly stratifies survival.
