Across TCGA pan-cancer cohorts, GPC6 mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated GPC6 data layer compared with 23 for mass-spec protein and 10 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher GPC6 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated GPC6 expression acts as an unfavorable survival marker, although some lineages such as LUAD show a favorable association.
PDAC, COAD, and CCRCC are the cancer types where GPC6 mass-spec protein most reproducibly stratifies survival.

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.
