Filter by:RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is looking at tissue samples from patients with breast cancer.
The purpose of this study is to determine the feasibility of a short term administration of a targeted therapy (i.e., anastrozole) in women with newly diagnosed early invasive or non invasive breast cancer during the interval between their breast biopsy and surgery. Anastrozole is a form of hormonal therapy which is part of the standard treatment for hormone sensitive breast cancer in postmenopausal women. This clinical model is being used to evaluate the biologic effects of this drug on a specific molecular pathway called the PI3K/AKT signaling pathway.
RATIONALE: Collecting and storing information from patients with cancer to study in the future may help doctors learn more about cancer. PURPOSE: This study is collecting information from patients enrolled in the Breast Specialized Program of Research Excellence.
The purpose of this research study is to determine how well the combination of bevacizumab and carboplatin works in treating breast cancer that has spread to the brain. Bevacizumab is an antibody (a protein that attacks a foreign substance in the body) that is made in the laboratory. Bevacizumab works differently from the way chemotherapy drugs work. Usually chemotherapy drugs attack fast growing cancer cells in the body. Bevacizumab works to slow or stop the growth of cells in cancer tumors by decreasing the blood supply to the tumors. When the blood supply is decreased, the tumors don't get the oxygen and nutrients they need to grow. Carboplatin is in a class of drugs known as platinum-containing compounds and has been approved for use in the treatment of ovarian cancer. Information from other research studies suggests that the combination of bevacizumab with carboplatin may be effective in treating breast cancer.
The purpose of this study is to assess the efficacy, safety and tolerability of 2 dosing regimens of BIIB021 in combination with exemestane in women whose HR+ breast cancer had progressed following treatment with a nonsteroidal aromatase inhibitor (AI).
The main purpose of this study is to determine if AZD8931 can be safely administered in Japanese patients alone and in combination with weekly paclitaxel. The study will be conducted in two parts: a monotherapy and a combination part, where safe doses of study treatment will be determined.
The purpose of this study is to observe the cosmetic outcomes, patient satisfaction, and complications after skin sparing mastectomy with preservation of the nipple areolar complex.
RATIONALE: Studying samples of tumor tissue and blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at tissue and blood samples from women with locally advanced or metastatic breast cancer
Breast cancer is the most common malignancy in the U.S. Targeted therapies such as tamoxifen have been revolutionary in reducing tumor recurrences and mortality in early breast cancer. Using this successful paradigm, there has been a continued search for other targeted biologic therapies directed at receptors with known potential for promoting tumor growth. The estrogen receptor (ER) and/or the HER signaling pathways are the dominant drivers of cell proliferation and survival in the majority of human breast cancers. Molecular targets of these pathways provide the most effective therapies in appropriately selected patients. However, de novo and acquired resistance remain major obstacles to successful treatment, and understanding the molecular pathways responsible for this resistance would enable the discovery of new strategies to overcome it. The superiority of multi-drug HER2-targeted therapy over single agent therapy has been demonstrated in the preclinical setting using mouse xenografts. Trastuzumab, pertuzumab, lapatinib, and gefitinib, represent a group of therapeutic agents that target the HER family by different molecular mechanisms. Used as single agents in the MCF7/HER2-18 xenograft model, these drugs restored or enhanced sensitivity to tamoxifen. However, tumor growth inhibition lasted only 2-3 months before resistance to treatments occurred. However, when gefitinib, a HER1 inhibitor, was added to the two-antibody (T+P) regimen to block signals from HER1 dimers, a complete disappearance of nearly all xenograft tumors was observed; moreover, there was evidence of complete tumor eradication in 50% of the mice. The combination of lapatinib + trastuzumab was also highly effective in eradication of tumor burden, with no evidence of re-growth after 200 days. These xenograft models demonstrate that multi-drug HER2-targeted therapy more effectively induces apoptosis and inhibits proliferation, thereby resulting in tumor regression. Furthermore, HER2 combination therapy appears to more effectively reduce levels of phosphorylated pAKT and MAPK, thus resulting in sustained tumor inhibition.
RATIONALE: Bimatoprost ophthalmic solution may help increase eyebrow and eyelash growth in patients who have undergone chemotherapy. PURPOSE: This randomized clinical trial is studying how wells bimatoprost ophthalmic solution works in increasing eyebrow and eyelash growth in patients who have undergone chemotherapy for breast cancer and in healthy participants.
