Across TCGA pan-cancer cohorts, PTGIS Mutation is linked to patient survival in 6 of 34 cancer types, making it a survival-associated PTGIS data layer compared with 21 for mass-spec protein and 4 for mass-spec protein.
The strongest signal is observed in bladder urothelial carcinoma (BLCA), where higher PTGIS Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated PTGIS expression acts as an unfavorable survival marker, although some lineages such as SKCM show a favorable association.
BLCA, ESCA, and STAD are the cancer types where PTGIS Mutation most reproducibly stratifies survival.
Mutation 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.
