摘要

在乳癌患者身上出現腸胃道轉移實屬少見，而此類患者中以侵襲性小葉癌為最常見之病理型態。因患者之非專一性之臨床症狀及浸潤性之轉移型態，使得早期診斷通常較為困難。我們在此呈現一名罹患侵襲性小葉癌的乳癌患者，其發生多處腸胃道轉移，包括胃、小腸、大腸及直腸。在給予全身性化學治療後，疾病獲得控制，後續改以維持性荷爾蒙療法治療。我們將討論此類少見族群常見的臨床表現、如何提高早期診斷的機率，以及目前可選用的治療方式。

Metastasis to the gastrointestinal (GI) tract is relatively infrequent for patients with breast cancer. Invasive lobular carcinoma (ILC) is the most common histological type of breast cancer with such a presentation. Nonspecific GI symptoms along with the infiltrative pattern of the metastatic lesions usually make early diagnosis difficult. Here we present a patient with ILC of the breast developing recurrent GI tract metastases involving the stomach, small intestine, colon, and rectum. The disease was treated and controlled by systemic chemotherapy initially, followed by maintenance hormonal therapy. We also discuss common clinical manifestations, diagnosis, and treatment options of the disease with such an infrequent presentation.
