Recent studies have reported GATA3 expression in neoplastic cells in patients with various malignant tumors, including breast cancer, gastric cancer, and neuroblastoma.[14–17] Some studies reported that decreased GATA3 expression in neoplastic cells compared to non-neoplastic cells was associated with poorer overall survival (OS) in breast cancer and gastric cancer. This evidence concerns the gene GATA3 and neuroblastoma.
