Across TCGA pan-cancer cohorts, KRT13 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated KRT13 data layer compared with 24 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher KRT13 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated KRT13 expression acts as an unfavorable survival marker, although some lineages such as HNSC and LSCC show a favorable association.
HNSC, PDAC, and LSCC are the cancer types where KRT13 mass-spec protein most reproducibly stratifies survival.
