Across TCGA pan-cancer cohorts, SBSN mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated SBSN data layer compared with 29 for mass-spec protein and 11 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher SBSN mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated SBSN expression acts as an unfavorable survival marker, although some lineages such as HNSC and CCRCC show a favorable association.
HNSC, LUAD, and CCRCC are the cancer types where SBSN mass-spec protein most reproducibly stratifies survival.
mass-spec protein survival associations by lineage
Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
