Active clinical trials for "Breast Neoplasms"

The scope of this study is to measure the impact of MammaPrint on treatment in Hormone Receptor (HR)-positive HER2-negative breast cancer patients. In addition, the impact of MammaPrint on treatment in patients with T1a/T1b and pN0/pN1 (up to 1 node), Triple Negative or HER2-positive tumors will be assessed.

This real-life Health Economics and Outcome Research (HEOR) study will enable to assess the impact of current therapies on quality of life (QoL), productivity loss and health care resource utilization in metastatic breast cancer (mBC). This prospective study will estimate patient-reported outcomes (PROs) and resource utilization data for mBC patients stratified according to treatment type, treatment line and disease status (progression vs. progression free) in a real-life setting. To estimate QoL, work productivity and health care resource utilization of post-menopausal patients with ER+/HER2- locally advanced or metastatic breast cancer in a real-life setting. The secondary objective is to estimate QoL and work productivity of mBC patients' caregivers. During the course of the study, data will be collected on quality of life and work productivity. Patients and caregivers will be asked to fill a set of questionnaires at their recruitment in the study, at 3 months and at 6 months after recruitment.

This is a molecular testing study for patients with metastatic breast cancer. The purpose of this study is to find defects in the DNA of the cancer that could potentially be treated with US Food and Drug Administration (FDA)approved or investigational drugs. For example, if your cancer has a mutation in the Epidermal Growth Factor Receptor (EGFR) gene (a mutation is a change int he DNA sequence of a gene) that makes this receptor "superactive" a drug that inhibits this receptor may also inhibit the growth of the cancer. If this genetic defect is not present in the cancer the same drug may not work. This EGFR gene mutation based patient selection for treatment has worked in lung cancer and we are testing its value in breast cancer. What drugs may be available against particular genetic abnormalities in the context of this clinical study will change over time.

The main clinical goal of NAC is to down-stage the primary tumor for BCS,yet BCS after NAC has been associated with significantly higher ipsilateral breast tumor recurrences.The accuracy of breast tumor excision in BCS can dramatically reduce IBTR.The main reseason of IBTR might be the uncertain shrinkage modes of the breast cancer after NAC.This clinical trial is firstly carried out to make clear the shrinkage modes of the primary tumor after 3 cycles and whole cycles of NAC,respectively,with whole-mount serial section(WMSS) and three-dimensional(3D) pathological reconstruction of the residual tumor.The second objective is to investigate the predictive value of 3D MRI reconstruction for the shrinkage modes of the primary tumor after NAC.

Relation between chemotherapy and amennorhea

A retrospective, observational, not EPA, multicenter study to evaluate the Clinical Benefit of Trastuzumab in Combination With Lapatinib in Metastatic Breast Cancer HER2 Positive Patients Who Has Been Previously Treated With Trastuzumab and/or Lapatinib between January 2005 and December 2011

This study will describe the treatment paradigm used over recent years in the clinical management of Human Epidermal Growth Factor Receptor 2 (HER2)+ metastatic breast cancer in Hungary. This information will provide insight into real-world exposure and adherence to anti-HER2 therapy containing regimens, and improve understanding of the reasons for discontinuation of this therapy. This is a retrospective, descriptive, cohort study of approximately 180 female patients diagnosed with HER2-positive metastatic breast cancer in Hungary. Patients diagnosed with, or who progressed to, metastatic disease between 01 September 2009 and 01 September 2010 will be included. All patients will be followed until death, loss to follow-up or the end of the study period (30 September 2012). All data will be collected retrospectively from patient medical records. Descriptive statistics of the demographic and clinical characteristics of HER2+ metastatic breast cancer patients, including sites of metastases, the time from initial breast cancer diagnosis until diagnosis of metastatic disease, and HER2 testing methodology and status of HER2 will be described. Further, descriptive statistics of the proportion of HER2+ metastatic breast cancer patients who received anti-HER2 therapy, the sequencing of different therapies, and the duration of therapies in the metastatic setting will be analysed. Among the subset of women who receive lapatinib plus capecitabine, descriptive statistics of the timing of initiation of lapatinib plus capecitabine in the metastatic treatment pathway, time to treatment discontinuation and time to progression (TTP) on lapatinib plus capecitabine will be calculated. Further, descriptive statistics of the type and duration anti-HER2 therapies used prior to initiation of lapatinib plus capecitabine and, where relevant, after lapatinib+capecitabine will be performed.

The goal of the study is to compare the radiologist confidence level in evaluating patients with known breast lesions using a carbon nanotube x-ray based stationary breast tomosynthesis imaging device. The comparison will be made against conventional mammography acquired as a part of a standard clinical workup. One hundred patients who are to have a clinical surgical breast biopsy will be recruited for the study. A reader study will be performed to evaluate the ROC characteristics of the system.

Oncotype DX® is likely to become more widely used in Europe as well as in Switzerland. The test is currently not reimbursed by the Swiss health insurances. The proposed study will investigate to what extent adjuvant treatment recommendations in breast cancer patients with an ER-positive tumor, made by Swiss tumor boards, are based on conventional factors, and whether the recommendations would change, when RS results from the Oncotype DX® test were available. In addition this study approaches the dilemma of adding adjuvant CT to adjuvant endocrine therapy in a systematic fashion. In this study, the St. Gallen consensus 2009 (with a minor update from the 2011 consensus, is used to predefine the patients suitable for endocrine therapy or chemo-endocrine therapy. Once results of this study are available they may help to better integrate Oncotype DX® with other factors. Currently, it is unclear how the different factors should be integrated into one recommendation. This study will provide data on the usefulness of this test for the two patient groups which are suitable for hormone therapy only and for those who are considered for hormone plus chemotherapy.

Rationale: The number of breast cancer (BC) patients at risk for long-term radiation-induced health problems is increasing, as their outcome is improving due to intensified treatment regimens, such as new systemic approaches and radiotherapy. Therefore, identifying BC survivors with the highest risk for radiation-induced health problems is crucial for developing strategies for primary and secondary prevention, which may contribute to healthy ageing.
