Across TCGA pan-cancer cohorts, ECM2 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated ECM2 data layer compared with 22 for mass-spec protein and 11 for mutation status.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher ECM2 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated ECM2 expression acts as an unfavorable survival marker, although some lineages such as HNSC show a favorable association.
UCEC, HNSC, and LSCC are the cancer types where ECM2 mass-spec protein most reproducibly stratifies survival.
