Across TCGA pan-cancer cohorts, SKA2 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated SKA2 data layer compared with 25 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher SKA2 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated SKA2 expression acts as an unfavorable survival marker, although some lineages such as LSCC show a favorable association.
PDAC, LUAD, and HNSC are the cancer types where SKA2 mass-spec protein most reproducibly stratifies survival.
