Letrozole for brain and scalp metastases from breast cancer--a case report.
Brain metastases from breast cancer have a poor prognosis. There have been reports of patients with breast cancer and brain metastases responding well to tamoxifen therapy. We report a very unusual case of intact breast carcinoma with brain as well as scalp metastasis responding well to letrozole (aromatase inhibitor) therapy for a prolonged period of time.
