Abstract
Case 1 : A 60-year-old woman underwent conservative breast surgery for breast cancer. Histopathological examination showed invasive lobular carcinoma (ILC) and advanced lymph node metastasis. She received postoperative chemotherapy (anthracycline followed by taxan) and endocrine therapy. Gastric metastasis was diagnosed 22 months after surgery. Case 2 : A 75-year-old woman underwent a modified radical mastectomy for breast cancer. The histopathological results were the same as in case 1. The patient received capecitabine therapy and endocrine therapy. Bone metastasis was diagnosed 9 months after surgery ; gastric and peritoneal metastases were diagnosed 31 months after surgery. Most patients with gastric metastasis from breast cancer have ILC as the primary pathology. In addition, most cases have multiple organ metastases at the time of diagnosis ; consequently the prognosis is poor. In this paper, our two cases of gastric metastasis from ILC of the breast are presented.
