Across TCGA pan-cancer cohorts, BCL2 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated BCL2 data layer compared with 22 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher BCL2 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated BCL2 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and HNSC show a favorable association.
UCEC, CCRCC, and HNSC are the cancer types where BCL2 mass-spec protein most reproducibly stratifies survival.
