Across TCGA pan-cancer cohorts, PLLP mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated PLLP data layer compared with 26 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher PLLP mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated PLLP expression acts as an unfavorable survival marker, although some lineages such as PDAC and CCRCC show a favorable association.
GBM, PDAC, and CCRCC are the cancer types where PLLP mass-spec protein most reproducibly stratifies survival.
