Across TCGA pan-cancer cohorts, HMG20B mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated HMG20B data layer compared with 26 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher HMG20B mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated HMG20B expression acts as an unfavorable survival marker, although some lineages such as LSCC show a favorable association.
LSCC, UCEC, and PDAC are the cancer types where HMG20B mass-spec protein most reproducibly stratifies survival.
