Active clinical trials for "Breast Neoplasms"

RATIONALE: Drugs used in chemotherapy, such as arsenic trioxide, use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: This phase II trial is studying how well arsenic trioxide works in treating women with locally advanced or metastatic breast cancer.

RATIONALE: Imaging procedures such as positron emission tomography (PET) may improve the ability to detect the extent of breast cancer. PURPOSE: Diagnostic trial to study the effectiveness of PET to detect the extent of breast cancer in women who have primary or recurrent breast cancer.

RATIONALE: The amount of dietary fat or fiber may affect estrogen metabolism in postmenopausal women, and this may affect the risk of developing cancer. PURPOSE: Randomized dietary intervention to study the effectiveness of a low-fat diet combined with either high fiber or low fiber on estrogen metabolism in healthy postmenopausal women.

RATIONALE: It is not yet known whether medroxyprogesterone is effective in preventing endometrial disorder in patients with breast cancer who are taking tamoxifen. PURPOSE: Randomized phase III trial to study the effectiveness of medroxyprogesterone in preventing endometrial disorder in postmenopausal women who have ductal carcinoma in situ, lobular carcinoma in situ, Paget's disease of the nipple, stage I breast cancer, or stage II breast cancer and who are taking tamoxifen.

RATIONALE: Diagnostic procedures, such as magnetic resonance imaging (MRI) using ferumoxtran-10, may help find and diagnose breast cancer that may have spread to the axillary lymph nodes and may help in planning breast cancer treatment. PURPOSE: This phase II trial is studying how well MRI using ferumoxtran-10 works in finding metastases to the axillary lymph nodes in patients with invasive breast cancer.

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. Indole-3-carbinol may be effective in preventing breast cancer. PURPOSE: Phase I trial to study the effectiveness of indole-3-carbinol in preventing breast cancer in nonsmoking women who are at high risk for breast cancer.

Patients will receive a maximum of 18 injections of dHER2 vaccine in a treatment schedule that will last for up to about a year, and thereafter there will be a follow-up period of about one more year.

The purpose of this study is to evaluate the use of an oral bisphosphonate (alendronate) in preventing bone loss in postmenopausal women with early breast cancer who are receiving anastrozole therapy, and to determine how long alendronate treatment is needed.

RATIONALE: Biopsy of sentinel lymph nodes and bone marrow may improve the ability to detect and determine the extent of cancer. PURPOSE: Phase III prognostic study of sentinel lymph node metastases and bone marrow metastases in women who have stage I or stage IIA breast cancer.

To address cardiovascular disease, cancer, and osteoporosis, the most common causes of death, disability, and impaired quality of life in postmenopausal women. The three major components of the WHI are: a randomized controlled clinical trial of hormone replacement therapy (HRT), dietary modification (DM), and calcium/vitamin D supplementation (CaD); an observational study (OS); and a community prevention study (CPS). On October 1, 1997, administration of the WHI was transferred to the NHLBI where it is conducted as a consortium effort led by the NHLBI in cooperation with the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), the National Cancer Institute (NCI), and the National Institute on Aging (NIA).
