Across TCGA pan-cancer cohorts, PRSS27 mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated PRSS27 data layer compared with 20 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher PRSS27 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated PRSS27 expression acts as an unfavorable survival marker, although some lineages such as HNSC show a favorable association.
HNSC are the cancer types where PRSS27 mass-spec protein most reproducibly stratifies survival.
