Across TCGA pan-cancer cohorts, MCC mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated MCC data layer compared with 26 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher MCC mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated MCC expression acts as an unfavorable survival marker, although some lineages such as HNSC and CCRCC show a favorable association.
LSCC, HNSC, and PDAC are the cancer types where MCC mass-spec protein most reproducibly stratifies survival.
