Filter by:The primary purpose of this study is to compare changes in the expression of the proliferation marker Ki-67 in malignant breast tissue after treatment with tibolone or placebo in postmenopausal women who need to undergo surgery for primary breast cancer
The goal of this study is to determine the feasibility based on toxicity and response rate of giving paclitaxel weekly with concomitant every-other week radiotherapy to limit skin toxicity. This study will also seek to determine the maximally tolerated dose of Navelbine added to this combination when followed by Filgrastim and the dose-limiting toxicities of this regimen.
The purpose of this study is to develop a computer-aided diagnosis system to find breast lesions, including masses and microcalcifications, which hopefully will improve breast cancer detection and classification.
The overall hypothesis is that the combination of a low dose of the antiestrogen Raloxifene with omega-3 fatty acids will exert a synergistic breast cancer chemopreventive effect due to the crosstalk of their downstream cellular effects leading to decreased proliferation and increased apoptosis of premalignant mammary cells. Based on the investigators hypothesis that upregulation of functional estrogen receptors in the premalignant lesions is also responsible for the development of hormone independent tumors, the investigators postulate that the combination of antiestrogens and omega-3 fatty acids will reduce the development of both hormone-dependent and -independent tumors. At present, there are no known interventions able to decrease the development of hormone-independent tumors, which are more prevalent, more aggressive, leading to the patient's demise. In addition, the investigators postulate that this approach will be safe since it will combine a lower and hence a less toxic dose of Raloxifene with the administration of omega-3 fatty acids which are known to have health benefits, i.e., reduction in cardiovascular risk, beyond their possible chemo preventive effect in breast cancer.
In the MDACC/BrUOG neoadjuvant trial with weekly paclitaxel followed by Fluorouracil Plus Doxorubicin and Cyclophosphamide (FAC), the pathologic complete response (pCR) rate in HER2(-) patients was 20%. The investigators' goal is to develop an induction chemotherapy regimen that will have a pCR rate above 30% in patients with HER2(-) disease. Based on a 1-sided 95% confidence interval using normal approximation with an expected pCR rate of at least 35%, approximately 28 patients are required for each cohort. With an assumed pCR rate of at least 35%, the investigators will have approximately 70% statistical power to conclude, with 90% certainty, that the pCR rate with the novel regimen exceeds 20%. The study will accrue approximately 60 patients in two cohorts with an inevaluable rate that does not exceed 10%.
The purpose of this study is to determine how well changes can be determined in malignant masses from ultrasound scans.
HER2 is a protein that sits on the surface of breast cancer cells in some people. Because you are one of these people, your breast cancer is called "HER2-positive." The HER2 protein is involved in the growth of your breast cancer. Certain drugs can interfere with the ability of the HER2 protein to cause breast cancer growth. Trastuzumab is one of these drugs. You must have already received trastuzumab as treatment for your breast cancer to be considered for this study. Other drugs are being studied in women with HER2-positive breast cancer. Lapatinib (Tykerb™) blocks signals that stimulate HER2-positive breast cancers to grow. The FDA approved lapatinib for use with capecitabine (Xeloda™) in patients who have metastatic breast cancer that has grown or spread after treatment with trastuzumab. Capecitabine was approved by the FDA in 1998 for treating metastatic breast cancer. Capecitabine is a pill that blocks the way cancer cells multiply and grow. Usually, this medicine is taken twice a day for fourteen days. Then, patients do not take the pill for seven days. With this schedule and dose, some patients have had side effects that interfered with their comfort. We have used mathematical models to recommend a new schedule of capecitabine. In animals, 7 days of treatment with capecitabine followed by a 7-day break was safer and more active against breast cancer. The purpose of this study is to find out what effect (both good and bad) capecitabine has on you and your breast cancer when given in this new schedule and combined with lapatinib.
"Translation" of the current "basic science" information related to physical activity into patient intervention programs is needed. This translation is critical to providing benefit to the maximum number of patients. Little is known about the determinants of physical activity among breast cancer patients undergoing hormonal therapy and few studies have attempted to evaluate an exercise behavior change program aimed to improve exercise adherence among such patients. The proposed project will evaluate use of an innovative behavioral and psychosocial intervention to increase physical activity among breast cancer patients.
The study will evaluate and refine a breast screening and diagnosis device.
The study is aimed to confirm that letrozole + PD 0332991 is safe and tolerable and to assess the effect of the combination on advanced breast cancer
