Across TCGA pan-cancer cohorts, PAM mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated PAM data layer compared with 23 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher PAM mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated PAM expression acts as an unfavorable survival marker, although some lineages such as PDAC show a favorable association.
CCRCC, LUAD, and UCEC are the cancer types where PAM mass-spec protein most reproducibly stratifies survival.
