Across TCGA pan-cancer cohorts, PBX2 mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated PBX2 data layer compared with 24 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher PBX2 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated PBX2 expression acts as an unfavorable survival marker, although some lineages such as LSCC and LUAD show a favorable association.
LSCC, GBM, and CCRCC are the cancer types where PBX2 mass-spec protein most reproducibly stratifies survival.
mass-spec protein survival associations by lineage
Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
