Across TCGA pan-cancer cohorts, MYB mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated MYB 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 MYB mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated MYB expression acts as an unfavorable survival marker, although some lineages such as HNSC show a favorable association.
HNSC are the cancer types where MYB mass-spec protein most reproducibly stratifies survival.
