The use of fulvestrant, a parenteral endocrine agent, in intestinal obstruction due to metastatic lobular breast carcinoma.

Background: The role of fulvestrant in the management of intestinal obstruction associated with lobular carcinoma has not been specifically described.

Case Presentation: Herein we present two cases where fulvestrant, as the only available parenteral endocrine agent for postmenopausal advanced breast cancer has the opportunity to provide a means to initiate treatment in those patients who present with varying degrees of intestinal obstruction.

Conclusion: Fulvestrant may obviate the use of chemotherapy while achieving sustained clinical benefit with less toxicity, in appropriately selected patients.
