Across TCGA pan-cancer cohorts, RTL8A mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated RTL8A 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 RTL8A mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated RTL8A expression acts as an unfavorable survival marker.
LSCC are the cancer types where RTL8A mass-spec protein most reproducibly stratifies survival.
