Across TCGA pan-cancer cohorts, VPS8 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated VPS8 data layer compared with 23 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher VPS8 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated VPS8 expression acts as an unfavorable survival marker, although some lineages such as HNSC and UCEC show a favorable association.
HNSC, CCRCC, and LSCC are the cancer types where VPS8 mass-spec protein most reproducibly stratifies survival.
