[A case of metastatic gastric cancer from breast cancer treated with proximal gastrectomy].

We report a case of a 72-year-old woman with breast cancer who developed significant stenosis due to gastric cardia metastasis. The patient had undergone radical mastectomy for breast cancer when she was 53 years old and had developed postoperative recurrent diseases in the sternum and lung when she was 62 years old. Nineteen years after mastectomy, computed tomography (CT) scans showed gastric cardia metastasis. As symptoms of cardiac stenosis gradually developed, we performed proximal gastrectomy. The specimen was histologically diagnosed as estrogen receptor( ER)-positive scirrhous carcinoma that had metastasized from the breast cancer. The patient resumed oral intake of food after surgery. Surgical treatment might be useful to improve the quality of life of patients with metastatic gastric tumor.
