Across TCGA pan-cancer cohorts, PDCD2L mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated PDCD2L data layer compared with 24 for mass-spec protein and 7 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher PDCD2L mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated PDCD2L expression acts as an unfavorable survival marker, although some lineages such as LUAD and PDAC show a favorable association.
LUAD, PDAC, and LSCC are the cancer types where PDCD2L mass-spec protein most reproducibly stratifies survival.
