Gastric Metastasis of Breast Cancer: A Case Series.
Gastric metastasis is rare but it can be the initial symptom of cancer. The second leading cause of this type of metastasis is breast cancer. A lack of clinical signs and nonspecific side effects of the treatment of primary tumors can lead to the misdiagnosis of metastatic gastric cancer. Upper gastrointestinal endoscopy with biopsy and immunohistochemistry should be used for diagnosis. Treatment is palliative; it includes chemo, endocrine, and radiation therapies. Four patients with breast cancer and gastric metastasis were identified. All the patients tested positive for estrogen and progesterone receptors, and received chemotherapy and hormone therapy. One patient underwent surgery and two received radiation therapy. Patients with breast cancer and gastrointestinal symptoms should be investigated for gastric metastasis, given its morbidity and negative impact on quality of life.
