Brief summary:
RATIONALE: Dehydroepiandrosterone (DHEA) may slow the growth of tumor cells and be an effective treatment for women with breast cancer.

PURPOSE: This phase I trial is studying how well DHEA works in treating women undergoing surgery for stage I, stage II, or stage III breast cancer.

Detailed description:
OBJECTIVES:

Primary

* To identify the effect of the adrenal steroid, dehydroepiandrosterone (DHEA), on tumor proliferation in women with estrogen receptor-negative, progesterone receptor-negative, HER2/neu-negative, and androgen receptor (AR)-positive stage I-III adenocarcinoma of the breast.

Secondary

* To study the effect of DHEA on expression of AR in these patients.
* To assess the effect of DHEA on changes in serum estrogen and androgen hormone levels (e.g., estrone, estradiol, testosterone, dihydrotestosterone, DHEA, and DHEA-sulfate) in these patients.
* To assess the toxicity of DHEA in these patients.
* To follow the clinical course of these patients.

OUTLINE: Patients receive oral dehydroepiandrosterone (DHEA) twice daily on days -14 to 0. Patients then undergo surgery on day 1.

Tissue samples are collected at baseline and at the time of surgery for biomarker analysis (androgen receptor, estrogen receptor, progesterone receptor, HER2/neu, Ki-67, and p53) by IHC. Blood samples are collected at baseline and after completion of treatment with DHEA for analysis of serum hormone (e.g., estrone, estradiol, testosterone, dihydrotestosterone, DHEA, and DHEA-sulfate) and cytokine levels.

After completion of study therapy, patients are followed up at 1 week and then every 6 months for 3 years.

Arms:
arm 1: Day-14 (approx. 2 wks prior to surgery): begin a 2 week course of DHEA; Day-7 (approx. 1 wk after starting treatment): answer question about pill diary; Day 0 (approx. 2 wks after starting treatment, within 48 hours prior to surgery;

Interventions: intervention 1: DHEA intervention 2: Surgical resection
Intervention descriptions: intervention 1: DHEA administration will begin approxiately 14 days prior to surgery. intervention 2: Surgical procedure of the invasive breast cancer
