Active clinical trials for "Breast Neoplasms"

RATIONALE: Drugs used in chemotherapy, such as liposomal doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Hyperthermia therapy kills tumor cells by heating them to several degrees above normal body temperature. Giving temperature-sensitive liposomal doxorubicin together with hyperthermia may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of temperature-sensitive liposomal doxorubicin when given together with hyperthermia in treating women with locally recurrent breast cancer.

MEK is a critical member of the MAPK pathway involved in growth and survival of cancer cells. PD-325901 is a new drug designed to block this pathway and kill cancer cells. The purpose of this study is to study the effectiveness of PD-325901 in patients with colon cancer, breast cancer, and melanoma. PD-325901 will be given by mouth as a pill twice a day, CT scans will be done and biopsies will be taken of a tumor before and once during treatment to measure the effects of the drug. Blood samples will be taken to measure the amount of drug in the blood.

Trastuzumab or Herceptin is an antibody directed against Her-2. Her-2 is a growth factor receptor which is present on the tumors of 25% of patients with breast cancer. The addition of trastuzumab to chemotherapy has been shown in a randomized clinical trial to increase the response rate to chemotherapy, the duration of response to chemotherapy, and to improve the duration of survival of patients with metastatic breast cancer. The anticancer mechanism of action of trastuzumab is unknown, but it is possible that trastuzumab acts by promoting antibody-dependent cell mediated cytotoxicity (ADCC), or direct killing of cancer cells by immune cells, triggered by antibodies bound to the surface of the cancer cell. G-CSF is a drug which is a growth factor for certain types of immune cells. G-CSF has two favorable effects on ADCC. G-CSF increases the pool of circulating cancer-killing immune cells, and G-CSF increases the strength of binding of cancer-killing immune cells to a specific part of the antibody. Therefore, priming with G-CSF significantly increases the efficiency of ADCC, and four days of treatment with G-CSF has been shown to optimize ADCC in some studies. Recent data from the investigators' laboratory indicates that chemotherapy can augment ADCC directed against tumor cells. The investigators' hypothesis is that pre-treatment with the drug G-CSF would increase the effectiveness of chemotherapy given with trastuzumab.

The purpose of this study is to find out what effects (good and bad) taking capecitabine for 12 weeks before surgery will have on women with breast cancer.

RATIONALE: Breast-conserving treatments such as radiation therapy or limited surgery are less invasive than mastectomy and may improve the quality of life. It is not yet known if breast-conserving treatments are as effective as mastectomy followed by radiation therapy in treating locally advanced breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of breast-conserving therapy with mastectomy followed by radiation therapy in treating women who have locally advanced breast cancer that has been previously treated with chemotherapy.

RATIONALE: Antineoplastons are naturally-occurring substances that may also be made in the laboratory. Antineoplastons may inhibit the growth of cancer cells. PURPOSE: This phase II trial studies the effectiveness of antineoplaston therapy in treating women who have stage IV breast cancer that has not responded to previous therapy.

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 oxaliplatin in treating women who have advanced or metastatic breast cancer that has not responded to previous chemotherapy.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy followed by autologous peripheral stem cell transplantation in treating women who have metastatic breast cancer.

This is a phase 1 open label multicentre study of SHR9549 administered orally in patients with advanced estrogen receptor (ER) positive human epidermal receptor 2 (HER2) negative breast cancer. The study design allows an escalation of dose with intensive safety monitoring to ensure the safety of patients. The study will determine the maximum tolerated dose(MTD). In addition, expansion cohort(s) at potential therapeutic dose(s) in patients will be enrolled to further determine the safety, tolerability, pharmacokinetics and biological activity of SHR9549.

The Adventist Health Study-2 is a long-term study, exploring the links between lifestyle, diet, and disease outcomes among Seventh-day Adventists. More than 96,000 church members from the U.S. and Canada are participating in the current study, AHS-2, conducted by researchers at the Loma Linda University School of Public Health.
