Filter by:The purpose of the study is to evaluate whether hCG will result in a decrease in breast density. High breast density has been associated with an increased risk in breast cancer. It has also been shown that decreasing density with a drug called tamoxifen has resulted in a decreased risk in breast cancer. The investigators are looking at the effect of hCG on breast density in people who are at increased risk of developing breast cancer and our theory postulates that through the hormonal actions of hCG and tamoxifen there would be a greater reduction in breast density in patients who are treated with hCG and tamoxifen versus patients treated with tamoxifen alone. Using this data the investigators will be able to hypothesize that the treatment of hCG will result in a reduction in breast cancer rates in the population and thus make available another drug which can be used to decrease the rates of breast cancer in the population
We hypothesize that Simvastatin administration would result in selective killing of the basal subtype of breast cancer, in particular, CD44+/CD24- breast cancer cells in primary tumor. We further hypothesize that tumor genomic changes would correlate with tumor response to Simvastatin. We are also looking to correlate Simvastatin biological effects with the expression pattern of initial status of primary tumor. In addition, we hypothesize that Simvastatin-induced tumor gene expression changes may correlate with tumor and plasma proteomics, peripheral blood mononuclear cell gene expression changes, and pharmacogenetics, and that these analyses may further refine the selection of patients most likely to benefit from Simvastatin.
The purpose of this study is to determine if AMG 386 in combination with either paclitaxel and trastuzumab or capecitabine and lapatinib is safe and well tolerated in subjects with HER2-positive locally recurrent or metastatic breast cancer. This is an open-label phase 1b trial and has 2 study parts. Study part 1 is a dose escalation study to determine a tolerable dose of AMG 386 in combination with paclitaxel and trastuzumab (cohort A) or with capecitabine and lapatinib (cohort B). Study part 2 is cohort expansion of the tolerable doses determined in part 1.
The purpose of this study is to evaluate the safety of mammaglobin-A DNA vaccine in metastatic breast cancer patients.
The goal of this clinical research study is to learn whether different ways of viewing echocardiogram pictures along with blood tests can help to see heart-related side effects of chemotherapy and trastuzumab earlier than the usual tests.
The purpose of this study is to evaluate postmastectomy radiotherapy in breast cancer patients with one to three positive nodes.
This is a multicenter, open-label, two-arm, 2-stage, Phase 2 study of NKTR-102 in patients with metastatic or locally advanced breast cancer whose disease has failed prior taxane-based treatment in the metastatic setting. Patients will be randomized 1:1 into one of two treatment arms. NKTR 102 will be administered at a dose level of 145 mg/m2 in both arms. In Arm A, NKTR-102 will be given on a q14d schedule. In Arm B, NKTR-102 will be given on a q21d schedule. Approximately 70 patients may be evaluated in this study with approximately 35 patients enrolled in each treatment arm.
The purpose of this study is to test metallic markers in the breast tissue after breast conserving surgery and to observe the metallic markers' stability in the breast for use as tumor bed markers and positioning devices for radiation treatment.
RATIONALE: Specialized radiation therapy, such as 3-dimensional conformal radiation therapy, that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Internal radiation uses radioactive material placed directly into or near a tumor to kill tumor cells. Giving these treatments after surgery may kill any tumor cells that remain after surgery. It is not yet known whether 3-dimensional conformal radiation therapy is more effective than internal radiation therapy when given after surgery in treating early-stage breast cancer. PURPOSE: This randomized phase II trial is studying 3-dimensional conformal radiation therapy to see how well it works compared with internal radiation therapy when given after breast-conserving surgery in treating women with stage I or stage II breast cancer.
Young women with breast cancer have an increased breast tissue density and conventional imaging tests such as mammography and breast ultrasound are less sensitive and specific for detecting breast cancer than in older breast cancer patients. Breast MRI is an emerging tool that has been proven to improve the ability to identify breast cancers by determining the extent of disease and also detect multifocal, multicentric and bilateral breast cancers. To date, the role of pre-operative breast MRI is not clearly defined. The investigators are proposing a study to evaluate the impact of preoperative breast MRI on surgical decision-making in breast cancer patients <= 50 years. This may lead to improved characterization of breast cancers in these younger patients that may ultimately result in lower local recurrence rates in the future. The additional information attained through the breast MRI may also guide the use of radiation, chemotherapy and/or hormonal therapy in these patients.
