Brief Summary:
The study aims to determine biological changes associated with a low vs high dose of omega 3 fatty acids, docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), over 12 months in women at risk for recurrent breast cancer. The objectives of the trial are to develop mammary epithelial, adipose tissue specific markers of exposure and response to omega 3 fatty acid supplements that can be carried forward into definitive intervention trials of omega 3 fatty acids for breast cancer prevention. The investigators will randomize 80 subjects with hormone receptor negative, HER-2/neu overexpression positive or negative breast cancer to either a high or low dose of omega 3 fatty acids. Using fine needle aspiration to procure cellular samples of breast epithelial and adipose tissue, the investigators will determine the effects of omega 3 fatty acids on mammary specific biomarkers of response.

Condition or disease Intervention/treatment Phase
Breast Cancer Dietary Supplement: omega 3 fatty acids Not Applicable

Detailed Description:
The study aims to determine biological changes that occur with a 12 month intervention of low (~0.9 g EPA+DHA/day) vs high dose (~5.4 g EPA+DHA/day) of omega 3 polyunsaturated fatty acids (PUFAs) in women survivors of hormone unresponsive breast cancer. The objectives of the trial are to develop unique mammary epithelial, adipose tissue specific markers of exposure and response to omega 3 fatty acid supplements that can be carried forward into definitive intervention trials of EPA, DHA/omega 3 PUFAs for breast cancer prevention. The investigators will randomize 80 subjects with hormone receptor negative, HER-2/neu overexpression positive or negative breast cancer to either a high or low dose of omega 3 PUFAs. Using fine needle aspiration to procure cellular samples of breast epithelial and adipose tissue, the investigators will determine the effects of omega 3 fatty acids on mammary specific biomarkers of response.

Criteria

Inclusion Criteria:

  • Prior diagnosis of Stage 0 to III breast cancer that is estrogen receptor negative, progesterone receptor negative with completion of definitive surgery, radiation therapy and/or chemotherapy.
  • Completion of chemotherapy or trastuzumab for > six months and of radiation therapy for > 2 months, as applicable and 5 years or less from completion of standard therapy.

  • Subjects on Coumadin or other anticoagulants.
  • Subjects with breast implants.
  • Subjects who have had radiation to both breasts or who have undergone bilateral mastectomies.
  • Barriers to fine needle aspiration sampling of breast adipose tissue and/or parenchymal breast tissue, including breast implants, history of radiation to both breasts, bilateral mastectomies, and/or insufficient breast adipose/parenchymal tissue for adequate fine needle aspiration (FNA) sampling.
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, hypertension, or psychiatric illness/social situation that would limit compliance with study requirements.
