Abstract

Breast cancer liver metastasis is often accompanied by multiple organ metastasis, which is considered a sign of poor prognosis. Therefore, surgical resection is not frequently indicated. Here, we report a case of long-term survival of a 62 year-old woman who was found to have a solitary 3 cm mass in the eighth segment of the liver during her first year post-surgical abdominal contrast-enhanced computed tomography. The patient had a history of cancer in the left D region of her breast, which was diagnosed based on histopathological evidence showing an invasive ductal carcinoma that was ER (+), PgR (+), and HER2 (-). The breast cancer was subsequently treated by partial mastectomy. Postoperative residual breast and axillary irradiation were performed and hormonal therapy with anastrozole was prescribed. The abdominal tumor was diagnosed as a liver metastasis from the breast cancer and laparoscopic assisted partial hepatectomy was performed. The patient refused postoperative chemotherapy and continued on hormonal therapy with letrozole for 5 years. Seven years after surgery, she remains alive and free of recurrences. This case demonstrates that surgical intervention may improve the survival prognosis of patients with oligometastasis from breast cancer.
