Across TCGA pan-cancer cohorts, EIF6 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated EIF6 data layer compared with 25 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher EIF6 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated EIF6 expression acts as an unfavorable survival marker, although some lineages such as LSCC and HNSC show a favorable association.
CCRCC, LSCC, and HNSC are the cancer types where EIF6 mass-spec protein most reproducibly stratifies survival.
