The pathological diagnosis was as follows: scirrhous carcinoma, nuclear grade 3, positive for lymph node metastasis (1/18), estrogen receptor-positive (95%), progesterone receptor-positive (30%), human epidermal growth factor receptor 2 (HER2)-negative (score 1+ on immunohistochemistry), and a high Ki-67 index (35%). This evidence concerns the gene ERBB2 and scirrhous adenocarcinoma.
