Vitamin D and Breast Cancer Biomarkers in Female Patients
Breast CancerRATIONALE: Vitamin D may help prevent breast cancer. PURPOSE: This randomized clinical trial is studying vitamin D and breast cancer biomarkers in female patients.

MK-2206+Endocrine Therapy in Patients With Hormone Receptor-Positive Breast Cancer
Metastatic Breast CancerThis is a phase Ib trial that evaluates the safety and tolerability of MK-2206 given in combination with exemestane +/- goserelin in pre- and post-menopausal patients with hormone receptor-positive metastatic breast cancer.

DWI in Assessing Treatment Response in Patients With Breast Cancer Receiving Neoadjuvant Chemotherapy...
Breast CancerRATIONALE: Imaging procedures, such as diffusion-weighted magnetic resonance imaging (DWI) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), may help in evaluating how well patients with breast cancer respond to treatment. PURPOSE: This research trial studies DWI and DCE-MRI in assessing treatment response in patients with breast cancer undergoing neoadjuvant chemotherapy.

Nutritional Supplements and Hormonal Manipulations for Breast Cancer Prevention
Breast CancerThe 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.

Axillary Sentinel Lymph Node Detection in Breast Cancers > 2 cm
Breast CancerThe purpose of this study is to evaluate the quality criteria of the SLN detection technique in breast cancer patients with a tumor size (clinical measurement) greater than 2 centimeters (rate of false negatives, rate of detection). Eligible patients will only be registered (no randomization). The estimated inclusion period is approximately 24 months. The duration of the research is 25 months (24 months for patient inclusion + 1 month for reception of results). The maximum participation duration of each patient is 1 month. The number of patients required in this multicentric and prospective study is 240 (16 participating centers).

CP-751871 In Treating Women With Early-Stage Breast Cancer That Can Be Removed By Surgery
Breast CancerRATIONALE: Monoclonal antibodies, such as CP-751871, 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. PURPOSE: This phase I trial is studying the side effects and best way to give CP-751871 in treating patients with early-stage breast cancer that can be removed by surgery.

Vitamin D in Postmenopausal Women at High Risk for Breast Cancer
Breast CancerThis is a phase II study which will enroll 20 postmenopausal women who are at high risk for breast cancer development. The goal is to determine whether a one-year intervention of high-dose vitamin D at 2 different doses (20,000 IU weekly or 30,000 IU weekly) will increase circulating blood levels of vitamin D and to obtain preliminary data on the biologic effects of vitamin D for breast cancer prevention.

Acolbifene in Preventing Cancer in Premenopausal Women at High Risk of Breast Cancer
Breast CancerThis phase II trial is studying how well acolbifene works in preventing cancer in premenopausal women at high risk of breast cancer. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of acolbifene may stop cancer from growing or coming back.

A Study of ZD1839 Effects on Cell Proliferation in Breast Cancer
Breast CancerThis is a Phase II, randomised, double-blind, placebo-controlled study. Subjects with histologically-confirmed oestrogen receptor negative (ER-), progesterone receptor negative (PgR-) primary breast cancer breast cancer will be randomly assigned in a 2:1 ratio to receive ZD1839 250 mg once daily or matching placebo for a total period of 5 weeks. Surgical intervention will take place after 4 weeks (on Day 29) and treatment will continue for 1 week after surgery.

Reducing Arm Morbidity in Pre- and Post-breast Cancer Surgery
Breast CancerThe overall aim of this pilot study is to explore the feasibility of a randomized trial to test the effectiveness of physical therapy, provided both pre- and post-surgery, on reducing arm morbidity and increasing health-related quality of life (HRQL) post-surgery.
