Across TCGA pan-cancer cohorts, KRT87P mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated KRT87P data layer compared with 23 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher KRT87P mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated KRT87P expression acts as an unfavorable survival marker, although some lineages such as HNSC and UCEC show a favorable association.
HNSC and UCEC are the cancer types where KRT87P mass-spec protein most reproducibly stratifies survival.
