DHEA in Treating Women Undergoing Surgery for Stage I, Stage II, or Stage III Breast Cancer

2014-08-27 03:19:31 | BioPortfolio

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.

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.

Medical and Biotech [MESH] Definitions

Works consisting of studies using a quantitative method of combining the results of independent studies (usually drawn from the published literature) and synthesizing summaries and conclusions which may be used to evaluate therapeutic effectiveness, plan new studies, etc. It is often an overview of clinical trials. It is usually called a meta-analysis by the author or sponsoring body and should be differentiated from reviews of literature.

A method of chemical analysis based on the detection of characteristic radionuclides following a nuclear bombardment. It is also known as radioactivity analysis. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

A major C19 steroid produced by the ADRENAL CORTEX. It is also produced in small quantities in the TESTIS and the OVARY. Dehydroepiandrosterone (DHEA) can be converted to TESTOSTERONE; ANDROSTENEDIONE; ESTRADIOL; and ESTRONE. Most of DHEA is sulfated (DEHYDROEPIANDROSTERONE SULFATE) before secretion.

A quantitative method of combining the results of independent studies (usually drawn from the published literature) and synthesizing summaries and conclusions which may be used to evaluate therapeutic effectiveness, plan new studies, etc., with application chiefly in the areas of research and medicine.

The analysis of an activity, procedure, method, technique, or business to determine what must be accomplished and how the necessary operations may best be accomplished.
