Outcome Measures
Primary Outcomes (1)
Change in Percent of Breast Epithelial Cells With Ki-67 Immunocytochemical Expression
Change over the course of study in the percent of breast epithelial cells expressing the proliferation marker Ki- 67/MIB-1 in hyperplastic benign breast tissue acquired by random periareolar fine needle aspiration pre-study and post-study.
12 months
Secondary Outcomes (2)
Change in Gene Expression
12 months
Breast Cancer Prevention Trial (BCPT) Symptom Checklist
12 months
Study Arms (2)
flaxseed lignan, SDG
EXPERIMENTALSecoisolariciresinol diglycoside
Placebo
PLACEBO COMPARATORMatched Placebo
Interventions
The placebo contains same filler materials as commercially available Brevail® but without active SDG.
1 capsule daily of secoisolariciresinol diglycoside (SDG)50mg
Eligibility Criteria
You may not qualify if:
- Candidates are ineligible for tissue screening if they meet any of the following conditions:
- Consumption of systemic antibiotics during the 3 weeks prior to baseline RPFNA. Systemic antibiotics reduce intestinal bacteria and thus the ability to convert SECO to ENL.
- Consumption of supplements containing SDG (flaxseed or sesame seed) during the 3 weeks prior to baseline RPFNA. ( Consumption of foods containing flaxseed or sesame seed are OK.)
- Use of any selective estrogen receptor modulator or aromatase inhibitor (tamoxifen, raloxifene, arzoxifene, acolbifene, anastrozole, exemestane, letrozole) within the previous 6 months.
- Currently enrolled on an interventional investigational study.
- Bilateral breast implants.
- Invasive breast cancer or other invasive cancer diagnosis within five years.
- Metastatic malignancy of any kind.excluding Hodgkin's or non-Hodgkin's lymphoma.
- Current anticoagulant use.
- Consumption of coumadin, fish oil, or other anticoagulants during the 3 weeks prior to baseline RPFNA.
- Any other condition or intercurrent illness that in the opinion of the investigator makes the subject a poor candidate for RPFNA or the trial.
- RPFNA performed in the follicular portion (day 1-10) of the menstrual cycle. Note that day 1 is defined as the first day of bleeding.
- RPFNA specimen exhibits hyperplasia +/- atypia (Masood score of ≥13) with ≥500 cells on the cytology slide.
- Ki-67 ≥2% positivity (≥500 cells).
- Willing to continue without oral contraceptives throughout the duration of the study participation (12 months). Non-oral contraceptives are permissible. If heterosexually active, must be agreeable to use some non-hormonal form of contraception during the trial or husband or partner must have had a vasectomy. (Safety of SDG during pregnancy has not been documented).
