Fulvestrant or Tamoxifen in Treating Postmenopausal Women Who Are Undergoing Surgery for Ductal Carcinoma in Situ of the Breast
Recruitment status was Active, not recruiting
RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using fulvestrant or tamoxifen may fight breast cancer by blocking the use of estrogen by the tumor cells. Giving fulvestrant or tamoxifen before surgery may be an effective treatment for breast cancer.
PURPOSE: This randomized clinical trial is studying how well giving fulvestrant or tamoxifen works in treating postmenopausal women who are undergoing surgery for ductal carcinoma in situ of the breast.
Drug: tamoxifen citrate
Procedure: conventional surgery
Procedure: neoadjuvant therapy
|Study Design:||Allocation: Randomized
Primary Purpose: Treatment
|Official Title:||A Pilot Clinical Trial to Evaluate the Biological Activity of Fulvestrant (Faslodex) in Breast Ductal Carcinoma (DCIS)|
- Molecular markers of the estrogen pathway as measured by immunohistochemistry at 3 weeks [ Designated as safety issue: No ]
- Mammographic breast density as measured by the Madena method at 3 weeks [ Designated as safety issue: No ]
|Study Start Date:||November 2004|
- Determine, preliminarily, the efficacy of neoadjuvant fulvestrant, in terms of molecular changes in markers of the estrogen pathway, cell proliferation and apoptosis, and the epidermal growth factor pathway, in postmenopausal women with newly diagnosed ductal carcinoma in situ of the breast.
- Determine the toxicity profile of fulvestrant in these patients.
OUTLINE: This is a randomized, placebo-controlled, pilot, multicenter study. Patients are randomized to 1 of 4 treatment arms.
- Arm I: Patients receive oral placebo once daily on days 1-21.
- Arm II: Patients receive oral tamoxifen once daily on days 1-21.
- Arm III: Patients receive fulvestrant intramuscularly (IM) on day 1.
- Arm IV: Patients receive fulvestrant IM as in arm III but at a higher dose. In all arms, treatment continues in the absence of disease progression or unacceptable toxicity. All patients undergo surgical resection of the tumor on approximately day 21.
PROJECTED ACCRUAL: A total of 100 patients (25 per treatment arm) will be accrued for this study.
