KLK8

Across TCGA pan-cancer cohorts, KLK8 mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated KLK8 data layer compared with 22 for mass-spec protein and 5 for mutation status.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher KLK8 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated KLK8 expression acts as an unfavorable survival marker, although some lineages such as HNSC show a favorable association.

HNSC and PDAC are the cancer types where KLK8 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.
