DataSheet_1_Case Report: Small intestinal metastatic breast cancer: A case report and literature review.pdf

Breast cancer is considered a malignant tumor with the highest incidence among women and is prone to develop distant metastasis. Small intestinal metastasis of breast cancer, however, is relatively rare. This case report describes a 49-year-old Chinese female patient who presented with small intestinal obstruction and was diagnosed with lobular breast cancer with small intestinal and contralateral breast metastasis. Clinical manifestations, clinicopathological features and potential mechanisms of metastasis, along with diagnosis and treatment, are discussed with a review of the relevant literature. Although small intestinal metastasis is rare in breast cancer, we should keep high alert on the possibility of gastrointestinal metastasis when treating lobular breast cancer patients.

乳腺癌被认为是女性群体中发病率最高的恶性肿瘤，且易于发生远处转移。然而，乳腺癌的小肠转移相对罕见。本病例报告报道了1例49岁中国女性患者，该患者以小肠梗阻为首发表现，最终被诊断为小叶性乳腺癌，且同时存在小肠转移与对侧乳腺转移。本文结合相关文献复习，对该病例的临床表现、临床病理特征、潜在转移机制以及诊疗方案进行了探讨。尽管乳腺癌合并小肠转移较为罕见，但在收治小叶性乳腺癌患者时，仍需高度警惕其发生胃肠道转移的可能性。
