Across TCGA pan-cancer cohorts, PRR9 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated PRR9 data layer compared with 24 for mass-spec protein.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher PRR9 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated PRR9 expression acts as an unfavorable survival marker, although some lineages such as HNSC and UCEC show a favorable association.

HNSC, UCEC, and LSCC are the cancer types where PRR9 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.
