Background
Breast cancer metastasis to the gastrointestinal tract (GIT) is rare. When it does occur, the upper GIT is more frequently involved, and lobular infiltrating carcinoma apparently has a greater apparent predilection for the GIT than the ductal type does. This study reviewed the clinicopathological features of esophagogastric secondary tumors from breast cancer.
Patients and Methods
Patients with breast cancer metastases to the upper GIT referred to us for treatment of either esophageal or gastric cancers between November 1997 and November 2004 were identified from our database. The medical records of these patients were then reviewed for clinicopathological data and outcome.
Results
Nine patients with mean age of 71 (range: 57–90) years had median time of 6.5
(2.8–32.8) years between primary breast cancer diagnosis and upper GI metastasis. The sites of metastatic lesions included the lower esophagus (2 patients), gastroesophageal junction (1 patient), gastric body (3 patients), and pylorus (3 patients). Histological typing indicated 7 cases of the lobular form and 2 cases of ductal carcinoma. All but one biopsy specimen were estrogen receptor and CK7 positive. Treatment included hormonal therapy and stent in 3 patients, hormonal therapy alone in 1 patient, chemotherapy alone in 1 patient, chemotherapy and gastrojejunostomy in 1 patient, dilatation and stent in 1 patient, and palliative care only in 2 patients. The median survival following treatment of these metastases was 20 (range: 2.1–96.6) months.
Conclusions
The onset of nonspecific GIT symptoms in patients with a history of breast carcinoma should prompt the clinician to rule out the possibility of upper GIT metastasis even many years after the original breast cancer. The use of systemic therapy for breast cancer may result in longer survival.
