Cox-OS analysis showed that THBS1-IT1 expression levels were associated with OS in adrenocortical carcinoma (ACC), bladder urothelial carcinoma (BLCA), glioblastoma multiforme (GBM), KIRC, brain lower grade glioma (LGG), mesothelioma (MESO), PAAD, STAD and THCA (Figure 6D, P < 0.05), and its high expression is a risk factor in these tumor types (HR>1). This evidence concerns the gene THBS1 and pancreatic adenocarcinoma.
