Across TCGA pan-cancer cohorts, NPPB mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated NPPB data layer compared with 20 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher NPPB mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated NPPB expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
UCEC are the cancer types where NPPB mass-spec protein most reproducibly stratifies survival.
