Across TCGA pan-cancer cohorts, TP53I3 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated TP53I3 data layer compared with 23 for mass-spec protein and 1 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher TP53I3 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated TP53I3 expression acts as an unfavorable survival marker, although some lineages such as CCRCC show a favorable association.
CCRCC, LSCC, and LUAD are the cancer types where TP53I3 mass-spec protein most reproducibly stratifies survival.
