Filter by:All women on tamoxifen receive the standard dose of 20mg QD, irrespective of the use of potential CYP2D6 inhibitors, and are not tested for CYP2D6 polymorphisms prior to start of tamoxifen treatment.However CYP2D6 polymorphisms and/or the use of CYP2D6 inhibitors as co-medication may influence the treatment outcome of tamoxifen. The investigators propose a prospective study in women taking tamoxifen at a dose of 20mg QD. In each woman, information will be collected on endoxifen levels, CYP2D6 status, adherence and use of co-medication. In women who are phenotypically poor metabolizers of tamoxifen, a dose increase to 40mg QD will be applied and the effect of this intervention on tamoxifen pharmacokinetics will be evaluated after 4 weeks.
LEP-ETU is a novel, proprietary delivery system of paclitaxel developed by NeoPharm, Inc. Paclitaxel (currently marketed as Taxol) is an anti-microtubular network agent and is active in a broad spectrum of malignancies. Paclitaxel has poor solubility. In order to enhance the solubility, this drug is formulated with polyoxyethylated castor oil, which leading to infusion-related hypersensitivity reactions. The NeoPharm LEP-ETU is formulated with a mixture of well characterized, synthetic phospholipids and cholesterol. This design eliminates the need for the oil. The LEP-ETU formulation has improved safety profile that is necessary for administering higher doses than would commonly be used with Taxol. The clinical evidence obtained from the NeoPharm Phase I study shows LEP-ETU is better tolerated than Taxol, as indicated by a higher maximum-tolerated dose (MTD). The current Phase II study is designed to accomplish the following objectives: 1. Assess the Overall Response Rate (ORR) of patients with metastatic breast cancer after administered over 90 minutes at the dose of 275 mg/m2 LEP-ETU 2. To evaluate the Progression-Free Survival (PFS) 3. To evaluate the safety of LEP-ETU at 275 mg/m2 level, in particular peripheral neuropathy 4. To evaluate the Overall Survival (OS)
The purpose of this study is: To validate the efficacy of multiparametric MRI, FDG-PET, RGD-PET, and PET-MR fusion imaging in the prediction and monitoring response to neoadjuvant chemotherapy of locally advanced breast cancer patients. To identify the optimal combination parameters of MR spectroscopy, diffusion-weighted MRI, dynamic contrast-enhanced MRI, FDG-PET, and RGD-PET in the prediction and monitoring response to neoadjuvant chemotherapy of locally advanced breast cancer patients. To compare the performances of dynamic contrast-enhanced MRI using parametric response map analysis versus those of pharmacokinetic parameters (Ktrans, kep, or Ve) in the early prediction of pathological responsiveness to neoadjuvant chemotherapy in breast cancer patients
The purpose of this study is to evaluate anti-cancer stem cell (CSC) activity (measured by the amount of Aldehyde dehydrogenase 1/ALDH1+ cells before and after treatment) of pre-operative bevacizumab in combination with conventional chemotherapy in breast cancer receiving neo-adjuvant treatment, compared to a control arm receiving chemotherapy alone.
Up to 200 patients with biopsy proven early stage breast cancer selecting Wide Local Excision (WLE) will undergo mammography, ultrasound (of affected breast and ipsilateral axilla) and contrast enhanced-magnetic resonance imaging (CE-MRI) of the affected breast to evaluate the extent of disease.
After treatment for Hodgkin disease, secondary cancer, in particular breast cancer induced by treatment, are the first cause of death. The investigators will estimate the risk to develop breast cancer in this population of women treated for hodgkin disease, and will propose women at high rish to participate in an intensive screening program based on an annual detection based on mammography, echography, and RMI.
This single arm observational study will assess the duration and safety of treatment with trastuzumab in routine clinical practice in participants with early or metastatic HER2-positive breast cancer. Data will be collected from female participants treated with trastuzumab according to the Summary of Product Characteristics and local protocols. Duration of observation for each participant is from therapy initiation until permanent discontinuation for any cause.
This is a randomized, Phase II, double-blind, multicenter, placebo-controlled trial designed to preliminarily estimate the efficacy and evaluate the safety and tolerability of onartuzumab (MetMAb) + bevacizumab + paclitaxel and onartuzumab + placebo + paclitaxel versus placebo + bevacizumab + paclitaxel in participants with metastatic or locally recurrent, triple-negative breast cancer who either have not received treatment (first-line) or have progressed after one conventional cytotoxic chemotherapy regimen (second-line).
The purpose of this study is to compare the effects of 3 different approaches to exercise training in women with early stage breast cancer who have completed all primary treatments (except hormone therapy, if appropriate). Prior research in women with early stage breast cancer has shown that some treatments may have an adverse impact on physical fitness levels leading to feelings of fatigue and poor quality of life. Supervised exercise training has been shown to reduce some of these side-effects. However, all the exercise programs have followed essentially the same approach. This study is designed to see if a different approach to exercise training is more effective than the conventional approach currently in use.
The purpose of this research study is to see what effects trastuzumab in combination with vinorelbine has on breast cancer when the participant has circulating tumor cells that are positive for the protein called HER2. Trastuzumab is an FDA approved drug that targets HER2. The drug combination of trastuzumab and vinorelbine is an effective treatment for patients with breast cancers that are positive for HER2. This trial seeks to determine if the combination can also benefit participants whose original breast cancer was HER2 negative but whose circulating tumor cells are HER2 positive.
