In contrast, in GBM, esophageal carcinoma (ESCA), and EGFR-mutant LUAD, we observed distinct features showing significantly increased abundance of myeloid dendritic cells (DCs), neutrophils, and fibroblasts (Fig. 2c) in 9p21-loss tumors and this observation was also supported by independent analysis of marker gene expression. The gene discussed is EGFR; the disease is glioblastoma.
