简要总结
This research study is designed to look at the effects of the combination of vorinostat (Suberoylanilide Hydroxamic Acid or Zolinza) and tamoxifen on breast cancer tissue. The investigators will do this by comparing tissues from the original breast biopsy to tissues obtained after taking vorinostat and tamoxifen for 2 weeks.
详细描述
Key eligibility criteria include:
- Newly diagnosed invasive breast cancer awaiting surgery or neoadjuvant (preoperative) treatment
- No use of hormone contraceptives or replacement therapy within 30 days prior to the diagnostic breast cancer biopsy (unless willing to have an additional biopsy prior to starting the study)
- No prior or current use of any therapy to treat the current breast cancer.

研究组 & 干预措施
Vorinostat and Tamoxifen
Vorinostat and tamoxifen are taken for about 14 days prior to definitive surgery.
干预措施: Vorinostat and Tamoxifen (Drug)
结局指标
主要结局
Changes in Markers of Proliferation Prior to and After Study Drug Administration
时间窗: Baseline and 14 days
To determine the percentage change in proliferation index Ki-67 in both ER-positive and ER-negative tumors between baseline and post-treatment biopsy following 14 days of vorinostat 400 mg PO once daily and tamoxifen 20mg PO once daily in women with primary breast cancer awaiting definitive surgery.
