Filter by:RATIONALE: Drugs used in chemotherapy, such as docetaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Lapatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether docetaxel and carboplatin are more effective when given together with trastuzumab and/or lapatinib in treating women with stage I, stage II, or stage III breast cancer. PURPOSE: This randomized phase II trial is studying how well docetaxel and carboplatin work when given together with trastuzumab and/or lapatinib in treating women with stage I, stage II, or stage III breast cancer that can be removed by surgery.
The purpose of this study is to compare the 1-year adherence to upfront adjuvant AI for postmenopausal, early stage breast cancer in the two observational arms; Standard Treatment and Standard Treatment plus PSP arm after one year
To determine the activity of the combination of paclitaxel, trastuzumab and carboplatin as neo-adjuvant treatment in patients with stage II or III HER2 positive breast cancer
This is a 90-day study to evaluate cosmetic outcome and Surgical Site Infection in approximately 100 patients from 6 centers in China undergoing scheduled modified radical mastectomy for breast cancer.
The aim of this study is to determine the effect of aromatase inhibitors therapy on bone mineral density and compare it to the effects of tamoxifen and no hormonal therapy.
The purpose of this study is to determine whether exemestane plus dasatinib will be well-tolerated and will increase progression-free survival (PFS) in the treatment of advanced estrogen-receptor positive (ER+) breast cancer after disease progression (PD) on a non-steroidal aromatase inhibitor (NSAI).
Research Question: Do Aromatase Inhibitors Decrease Intestinal Calcium Absorption? Study Design: Postmenopausal women with early stage breast cancer initiating aromatase inhibitor adjuvant therapy will participate in this two-month study. The primary study outcome is the change in intestinal calcium absorption following such therapy. Secondary outcomes are the changes in bone resorption markers and musculoskeletal signs and symptoms after initiation of therapy. We will interview women and review their medical records to determine eligibility. Eligible subjects will undergo two calcium absorption studies. The first study will determine their baseline calcium absorption, and the second study will occur after taking an aromatase inhibitor daily for at least 6 weeks. Women will present to the research unit in the early morning and receive an oral and intravenous stable calcium tracer with breakfast. Over the next 24 hours, we will collect all urine for measurement of its calcium content. During each inpatient stay, we will assess musculoskeletal symptoms by questionnaire and joint examination. Each woman will complete a four-day diet diary twice during the study.
RATIONALE: Studying samples of urine 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. PURPOSE: This study is looking at urine and blood samples in women with newly diagnosed breast cancer.
There are three main objectives, centering on those patients targeted for surveillance imaging. The first objective is to compare image quality and specificity of breast tomosynthesis and conventional 2D mammography in a BIRADS 3 diagnostic population. The second objective is to compare image quality and ability to determine post-surgical and post-radiation changes from recurrence in a post-cancer subset of a BIRADS 3 population having undergone conservation therapy (lumpectomy with or without radiation. The final objective is to compare image quality and the ability to determine chemoresponsiveness in a post-cancer subset of a BIRADS 3 population, who are undergoing neoadjuvant chemotherapy.
Aromatase Inhibitors (AI) are effective for secondary prevention of breast cancer and may soon replace tamoxifen as first-line therapy in the treatment of hormone-sensitive breast cancer. However, because these medications produce a marked reduction in serum estrogen levels, this is likely to result in an increased rate of bone loss and risk of developing osteoporosis and fractures in postmenopausal women treated with these agents. Indeed, substantial bone loss has been reported in several large clinical trials of AIs. Osteoporosis drugs are available that could prevent this loss, but they have frequent side effects and are expensive. Thus, treating all women receiving AIs might not be the most appropriate and cost-effective approach. A better approach might be to select women at highest risk of bone loss and only treat them with antiresorptive agents. The proposed pilot study will evaluate women who receive anastrozole or letrozole therapy, are receiving adequate amounts of calcium and vitamin D and have baseline normal or moderately low bone mass in order to determine if early changes in bone turnover markers correlate with bone loss at one year. If data from this pilot protocol support our hypothesis, then we would propose a larger trial to confirm it. The ultimate aim is to predict which women are at higher risk of bone loss and therefore treat them earlier with bone-sparing agents, while those with lower risk could be monitored on conservative therapy.
