Across TCGA pan-cancer cohorts, MT1M mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated MT1M data layer compared with 22 for mass-spec protein and 9 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher MT1M mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated MT1M expression acts as an unfavorable survival marker, although some lineages such as LSCC and CCRCC show a favorable association.
LSCC, CCRCC, and LUAD are the cancer types where MT1M mass-spec protein most reproducibly stratifies survival.
