High-Dose Esterified Estrogens in Treating Postmenopausal Women With Metastatic Breast Cancer That Has Failed Previous Hormone Therapy
Phase II Study of High-Dose Estrogen in Postmenopausal Women With Hormone Receptor-Positive Metastatic Breast Cancer After Failure of Sequential Endocrine Therapies
RATIONALE: High doses of esterified estrogens may stop the growth of breast cancer cells that no longer respond to hormone therapy.
PURPOSE: This phase II trial is studying how well high-dose esterified estrogens work in treating postmenopausal women with metastatic breast cancer that has failed previous hormone therapy.
研究概览
详细说明
OBJECTIVES:
Primary
- Determine the clinical response rate in postmenopausal women with estrogen and/or progesterone receptor-positive metastatic breast cancer that has failed prior sequential endocrine therapy treated with high-dose esterified estrogens (Menest^®).
Secondary
- Determine time to disease progression in patients treated with this drug.
- Determine the toxic effects of this drug in these patients.
OUTLINE: Patients receive oral high-dose esterified estrogens (Menest^®) 3 times daily. Treatment continues in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed for 2 months.
PROJECTED ACCRUAL: A total of 18-35 patients will be accrued for this study within 2 years.
