The subjects in this trial have been diagnosed as having a pre-cancerous disease of the breast called ductal carcinoma in situ (DCIS). This condition is associated with the development of breast cancer in up to 50% of cases.
The subjects are being asked to participate in this research study. They are being offered voluntary admission to this study to test the effects of a new investigational drug called Fulvestrant (Faslodex). This drug is approved by the United States Food and Drug Administration (FDA) for the treatment of advanced breast cancer but has not been approved for the treatment of DCIS. However, the FDA has given permission for the drug to be tested in this study. The purpose of this study is to find out if Fulvestrant has any effect on the subject's precancerous changes by comparing samples taken before and after receiving Fulvestrant.

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. ...
This is a Phase 2 study to demonstrate the safety and efficacy of SFX-01 when used in combination with aromatase inhibitors (AIs), tamoxifen and fulvestrant. Patients will be enrolled int...
To study progression free survival for treatment with Fulvestrant compared to treatment with tamoxifen in Metastatic Breast Cancer.
This is an open-label, non-randomized pharmacokinetic study of pre-surgical fulvestrant in women scheduled for mastectomy. Eligible subjects will be identified with breast cancer or DCIS, ...
The purpose of this study is to find out what effect the combination of fulvestrant (Faslodex) and dasatinib (Sprycel) has on advanced breast cancer compared to fulvestrant alone.
The estrogen receptor-alpha (ERα) is used as a predictive marker for anti-estrogen therapy in breast cancer patients. In addition to aromatase inhibitors, ERα can be targeted at the receptor level u...
In the SWOG S0226 trial the combination of anastrozole plus fulvestrant (n=349) was superior to anastrozole alone (n=345) in hormone receptor (HR)-positive metastatic breast cancer. Here we report a p...
Orally bioavailable SERDs may offer greater systemic drug exposure, improved clinical efficacy, and more durable treatment outcome for patients with ER-positive endocrine-resistant breast cancer. We r...
Although endocrine therapy is successfully used to treat patients with estrogen receptor (ER) positive breast cancer, a substantial proportion of this population will relapse. Several mechanisms of ac...
Estrogen receptors (ERs) are an important target for the management of breast cancers. Selective estrogen receptor down-regulators (SERDs) block ER activity, as well as reduce ERa protein levels in ce...
A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)
An invasive (infiltrating) CARCINOMA of the mammary ductal system (MAMMARY GLANDS) in the human BREAST.
A transplantable, poorly differentiated malignant tumor which appeared originally as a spontaneous breast carcinoma in a mouse. It grows in both solid and ascitic forms.
A noninvasive (noninfiltrating) carcinoma of the breast characterized by a proliferation of malignant epithelial cells confined to the mammary ducts or lobules, without light-microscopy evidence of invasion through the basement membrane into the surrounding stroma.
Neoplasms, usually carcinoma, located within the center of an organ or within small lobes, and in the case of the breast, intraductally. The emphasis of the name is on the location of the neoplastic tissue rather than on its histological type. Most cancers of this type are located in the breast.
