Across TCGA pan-cancer cohorts, SF3A2 mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated SF3A2 data layer compared with 24 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher SF3A2 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated SF3A2 expression acts as an unfavorable survival marker, although some lineages such as LSCC and GBM show a favorable association.
LSCC, HNSC, and GBM are the cancer types where SF3A2 mass-spec protein most reproducibly stratifies survival.
