Active clinical trials for "Breast Neoplasms"

This randomized controlled trial tests the hypothesis that a reduction in intake of dietary fat will reduce the incidence of breast cancer. Women with more than 50% of the breast occupied by dense tissue on a mammogram have been recruited and allocated by a random (ie chance) process, to an intervention or control group. The intervention group has been taught how to reduce their fat intake to a target of 15% of total calories, while the control group continued their usual consumption of fat. Both groups have then been followed for at least 7 years and the number who develop breast cancer in each group will be compared

RATIONALE: Lifestyle factors, such as physical activity, diet, and obesity, and hormone function may affect breast density. Screening tests, such as mammography, may help doctors find tumor cells early and plan better treatment for breast cancer. PURPOSE: This clinical trial is studying the effect of lifestyle factors and hormone function on breast density in healthy Hispanic women who are undergoing mammography for breast cancer screening.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of gemcitabine in treating elderly women who have metastatic breast cancer.

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of raloxifene may be an effective way to prevent breast cancer in premenopausal women. PURPOSE: Phase II trial to study the effectiveness of raloxifene in preventing invasive breast cancer in premenopausal women.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. St. John's wort may interfere with the effectiveness of chemotherapy. It is not yet known if chemotherapy is more effective with or without St. John's Wort in treating solid tumors. PURPOSE: Randomized phase III trial to compare the effectiveness of docetaxel with or without St. John's wort in treating patients who have solid tumors that cannot be removed by surgery.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Antineoplastons are naturally occurring substances that may also be made in the laboratory. Antineoplastons may inhibit the growth of cancer cells. It is not yet known whether giving antineoplastons with chemotherapy is more effective than chemotherapy alone in treating women with refractory breast cancer. PURPOSE: This randomized phase II trial is studying methotrexate alone to see how well it works campared to methotrexate and antineoplaston therapy in treating postmenopausal women with advanced refractory breast cancer.

RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using raloxifene and tamoxifen may fight breast cancer by blocking the uptake of estrogen by the tumor cells. PURPOSE: Randomized double-blinded clinical trial to compare the effectiveness of raloxifene with that of tamoxifen in preventing breast cancer in postmenopausal women.

RATIONALE: Screening tests may help doctors detect cancer cells early and plan more effective treatment for breast cancer. Diagnostic procedures such as MRI may improve the ability to detect breast cancer. PURPOSE: Screening and diagnostic trial to study the effectiveness of MRI scans in women who are at high risk for developing breast cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy. Donor lymphocytes may attack and destroy cancer cells. PURPOSE: This phase II trial is studying the effectiveness of combination chemotherapy, peripheral stem cell transplantation, and donor lymphocyte infusion in treating women with stage IV breast cancer.

This is a Phase 1b, open-label, non-randomized, Dose Confirmation study. Subjects will be treated, once a week, with IV doses of Nerofe and low dose (20 mg/m2) Doxorubicin (6-8 hours from one another) in consecutive, 28-day cycles.
