SCCA Breast Cancer Clinical Trials
|Recruiting||Breast Cancer||Phase II||
Risk Level Required for RPFNA Screening for Eligibility
- Given the low probability of side effects and the desire to be able to generalize results to a moderate as well as high risk population, the target cohort is pre-menopausal women who have a relative risk for breast cancer which is 2-fold or greater than that of the average woman in their age group by virtue of any one of the following conditions:
- A 1st or 2nd degree relative with breast cancer diagnosed under the age of 60
- A prior biopsy indicating proliferative breast disease, atypical hyperplasia, or LCIS
- Multiple prior breast biopsies regardless of histology
- 50% or higher estimated mammographic density on visual inspection
- Prior or current RPFNA evidence of atypia
- Known carrier of a BRCA1 or 2 mutation.
- Age, Life-Style and Medical Eligibility Criteria for Tissue Screening
Candidates for tissue screening for this study are pre-menopausal women who meet the risk criteria above and all of the following demographic and medical criteria:
- Age 21 to 49 (limiting the maximum age to 49 will reduce the possibility of reduction in Ki-67 due to entry into menopause transition during the study).
- Stable hormonal status for the previous 6 months (has not stopped or started oral contraceptives, or experienced lactation or pregnancy) and willing to maintain same status while on study.
- BMI < 40 kg/m2.
- Has had at least 4 menstrual cycles in past year
- If regularly undergoing screening mammography, must have been performed within 9 months prior to baseline RPFNA, and interpreted as not suspicious for breast cancer
Breast exam interpreted as normal (not suspicious for cancer).
- Exclusion Criteria for Screening RPFNA and Study Participation
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, acolbifine, 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.
- Inclusion Criteria for Study Entry
- 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).
- Have reasonable organ function as documented by metabolic chemistry profile.
- Willing to undergo a history and physical at baseline and 12 months and be contacted periodically by the trial coordinator during the 12 month study period.
- Willing to have blood drawn at baseline and twelve months.
- Able to understand and willing to provide informed consent for the RPFNA's and study participation.
