Across TCGA pan-cancer cohorts, COQ10B mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated COQ10B data layer compared with 24 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher COQ10B mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated COQ10B expression acts as an unfavorable survival marker, although some lineages such as HNSC show a favorable association.
LUAD, HNSC, and PDAC are the cancer types where COQ10B mass-spec protein most reproducibly stratifies survival.
