The analysis demonstrated that only 6 of the previously suggested prognostic markers included in the list, namely ABCC3 in GBM, CDX2, KIT, and WT1 in LAML and CEACAM5 in LIHC and STAD, are differentially expressed between tumor and healthy tissue, and 3 of them (ABCC3, KIT, and WT1) demonstrate a significant correlation between increased expression levels and poor survival (p-value < 0.05) (Tables S8 and S9). Here, CEACAM5 is linked to glioblastoma.
