e21136 Background: We treated a patient with breast cancer associated with multiple endocrine neoplasia type 1 (MEN 1). There are only few studies of the development of breast cancer in patients diagnosed with MEN1 syndrome. Methods: We found that patient had a pituitary macroadenoma that secretes prolactin (prolactinomas), increased serum concentration of calcium, 4.09 mmol/l and increased serum concentration of PTH, 212 pg/ml. Neck ultrasound and scintigrafy showed suspicious adenoma in lower left parathyroid gland. A computed tomography scan of the abdomen revealed a tumor mass in the body of the pancreas and adenoma in the left suprarenal gland. We diagnosed multiple endocrine neoplasia type 1 (MEN 1). Results: MEN1 occurs as a result of inactivating mutations of the MEN1 gene (MEN1), located on chromosome11q13. Results indicate that menin is a direct activator of ERalpha function. In a clinical study, in Kagawa, with 65 ER-positive breast cancer samples-all of which had been treated with tamoxifen for 2-5 years as adjuvant therapies-menin-positive tumors had a worse outcome than menin-negative ones. This indicated that menin can function as a transcriptional regulator of ERalpha and is a possible predictive factor for tamoxifen resistance.These results demonstrate that allelic deletions of the 13q12-14 region occur in some pituitary adenomas and 16% of parathyroid adenomas. Conclusions: As recent molecular studies have suggested genetic mutations in multiple endocrine neoplasia type 1, this syndrome may possibly predispose patients to breast cancer.This possibility cannot be evaluated definitively on the basis of a single case report; additional observations and studies are necessary to investigate this hypothesis further.
