Summary
Brief summary (as posted)
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using arzoxifene hydrochloride may fight breast cancer by blocking the use of estrogen by the tumor cells. PURPOSE: This randomized phase II trial is comparing two different doses of arzoxifene hydrochloride to see how well it works in treating women with advanced or metastatic breast cancer.
