About this study

This phase II trial compares leuprolide to goserelin for reducing estrogen production by the ovaries in pre- or peri-menopausal women with breast cancer. Estrogen can cause the growth of breast cancer cells. Both leuprolide and goserelin lower the amount of estrogen made by the body. This may help stop the growth of tumor cells that need estrogen to grow. This study compares lower dose leuprolide, higher dose leuprolide, and goserelin for their ability to suppress the function of the ovaries to produce estrogen. Both doses of leuprolide may be as safe, tolerable and/or effective as goserelin in suppressing ovarian function in pre- or peri-menopausal women with breast cancer.
