Across TCGA pan-cancer cohorts, OSTC mass-spec protein is linked to patient survival in 7 of 34 cancer types, making it a survival-associated OSTC data layer compared with 25 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher OSTC mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated OSTC expression acts as an unfavorable survival marker, although some lineages such as HNSC show a favorable association.
HNSC, LUAD, and CCRCC are the cancer types where OSTC 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.
