The expression of the human epidermal growth factor receptor-2 (Her-2) gene in patients with EC was found to be associated with tumor tissue differentiation, deep myometrium invasion (DMI), lymph node metastasis (LNM), and lympho-vascular space invasion (LVSI), which affects clinical treatment decisions (5). This evidence concerns the gene ERBB2 and metastatic malignant neoplasm in the lymph nodes.
