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.

Further study details as provided by University of Southern California:

Primary Outcome Measures:
  • Number of Participants With Molecular Changes in Markers of Cell Proliferation and Apoptosis Associated With Treatment [ Time Frame: 6 months after treatment of last patient enrolled ]
    Molecular measures of effect will be measured in tissue obtained at baseline biopsy (paraffin specimen) and on surgical specimen obtained at end of 3 weeks of treatment.

Secondary Outcome Measures:
  • Number of Participants With Changes in Mammographic Density [ Time Frame: 6 months after treatment of last patient enrolled ]
    The mammograms will be scanned and a validated computer based threshold method will be used to determine the mammographic densities.

Enrollment: 4

  • There must be available tissue from the diagnostic biopsy to perform molecular markers.
  • Baseline mammogram within 8 weeks of study entry.
  • Serum creatinine less than or equal to 2.0 mg/dl.

  • Peripheral neuropathy grade 0-1.
  • No prior therapy for DCIS.
  • SWOG performance status of less than or equal to 1
  • All patients must provide informed written consent

Exclusion Criteria:

  • Prior hormonal therapy (antiestrogens, estrogen, SERM's, progestins, or aromatase inhibitors) within 6 months of study entry.
  • Underlying medical, psychiatric or social conditions that would preclude patient from receiving treatment.
  • History of DVT or Pulmonary Embolism
