Filter by:The purpose of this study is to determine whether four new alternative imaging methods can be used to follow the response of breast cancer to the treatment patients are being given. These methods produce an image of the inside of the breast so that doctors can better decide whether breast cancer is responding to therapy. An important part of the study is to examine the same person with all methods in order to directly compare results. The four methods are: MRI Elasticity Imaging (abbreviated MRE), Electrical Impedance Spectroscopy (abbreviated EIS), Microwave Imaging and Spectroscopy (abbreviated MIS), Near Infrared Spectroscopy (abbreviated NIR). In addition to the experimental imaging methods, patients may also undergo a contrast-enhanced MRI, and/or additional mammography, which will help researchers compare the experimental methods. These additional examinations are accepted diagnostic procedures; they are not experimental. Some participants will have one or both of these additional examinations if clinically indicated.
Breast cancer is the most commonly occurring cancer in women. Currently, breast conservation surgery (BCS) is the treatment most often prescribed. BCS involves removing the tumor while conserving the greatest amount of healthy breast tissue. Under standard white light, tumor borders are difficult for the surgeons to visualize. Therefore, between 30-70% of patients require a second operation to remove remaining cancerous tissue that wasn't detected during the initial surgery. Thus, there is an urgent clinical need for a new imaging tool that improves tumor visualization during the first surgery. PRODIGI, a new hand-held optical imaging device, uses a safe violet-blue light to detect fluorescence signals in the tissue. Different tissues are associated with specific fluorescent colors and therefore the device can be used to differentiate between tumor and healthy breast tissue. Based on previous clinical data, PRODIGI can distinguish some tumors from normal tissues, but is not specific enough to detect a difference across all breast tumor types. The fluorescent contrast drug 5-aminolevulinic acid (5-ALA) accumulates in tumors naturally and previous research has shown that 5-ALA increases tumor-normal tissue fluorescence contrast. In this observational clinical study, PRODIGI and 5-ALA will be used to visualize tumor borders during BCS. 5-ALA induced fluorescent images from the surgical sample and the surgical bed obtained by PRODIGI will be compared retrospectively with the images taken under standard white light and/or autofluorescence. The technology's ability to accurately identify tumor borders better than conventional practice will be confirmed by tissue pathology.
Women who are overweight or do not exercise are at higher risk for breast cancer after menopause. This study will test a new electronic device that measures the body's movement and works alongside a website to help women increase their physical activity level. If effective, this system could be tested in larger studies aiming to reduce breast cancer risk by reducing or preventing obesity.
POL6326 will be given by i.v. infusion over 2 hours. Treatment will occur on days prior to, on the day of and on days after treatment with eribulin. Different doses and dosing frequencies will be investigated
There are three major subtypes of breast cancer: 1. Hormone receptor positive (contain cells that express the estrogen receptor or progesterone receptor). 2. Tumors that express the epidermal growth factor receptor gene ( HER-2) 3. Triple negative (cancer cells that lack the hormone receptors and the epidermal growth factor receptor gene HER-2. While effective therapies exist for most cases of breast cancer at first occurrence, many patients eventually exhibit disease that does not respond to all standard breast therapies, particularly in the metastatic setting. There are therapies that are used to treat other types of cancers with genetic mutations that are in the process of being evaluated for use in breast cancer. The current techniques used for detecting mutations in the genes of breast cancer patients, which can be treated with drugs specific for the genetic mutations, are invasive and identifying effective diagnostic non-invasive procedures are the next challenge for physicians. This study will compare the ability to detect genetic mutations samples from non-invasive procedures such as a blood draw, to more invasive procedures such as tissue taken from a biopsy sample. There is also a concern with current techniques used to detect genetic mutations that cells from a single tissue sample may not be representative of the types of cells present in all the tumors in the body and therapies selected using a single tissue sample may not be effective for all of the cancer in the body. This study will use blood drawn from participants prior to any drug therapy and compare the genes from this blood to tissue samples from multiple sites of disease. The study will also compare the genetic profile of the metastatic tumors to the genetic profile of the original breast cancer to determine if there are any changes in the genetics of the tumor cells. The participants that have newly diagnosed metastatic disease will provide tissue from their primary site of disease via an image guided biopsy. These participants will also provide tissue from at least 2 other distant metastatic sites (lung, pleural/peritoneal, liver, brain, or skin). Each biopsy procedure will attempt to obtain 2-3 samples for research purposes. Participants that have locally recurrent disease in the breast will have the tissue from the site of re-occurrence biopsied as well as two distant metastatic sites (lung, pleural/peritoneal, liver, brain, or skin). Participants that have either multi-centric disease or bilateral disease will have all tumors sampled with the intention of providing 2-3 samples/tumor for research purposes. Participants with multi-centric and bilateral disease will also have 2 distant sites of distant disease sampled (lung, pleural/peritoneal, liver, brain, or skin). Prior to any scheduled biopsy procedures all participants will have a blood draw used to examine the genetics of the tumor cells in the blood. The participants will have 8 tubes of blood drawn for the test and then they will proceed onto the tissue sampling portion of the study.
In HER2-positive metastatic breast cancer, trastuzumab based treatment is the standard of care as long as there are no contraindications to trastuzumab. Frequently, trastuzumab is being combined with taxanes in the first-line setting. However, since therapy with trastuzumab is active even in the absence of chemotherapy in HER2-positive MBC, the optimal treatment strategy either in combination or in sequence with chemotherapy is still under debate. This randomized phase II trial is studying a new strategy for the treatment of metastatic breast cancer with HER2-positive. First-line treatment consists of trastuzumab and pertuzumab, a treatment without chemotherapy. In case of disease progression, chemotherapy with T-DM1 is then performed as second-line treatment. Third-line and further line therapies are performed according to the physician's discretion. If this new therapeutic strategy is as effective and better tolerated than the conventional strategy, this would mean a serious breakthrough in the treatment of HER2-positive metastatic breast cancer.
The study is a single arm prospective study, aiming at identifying biomarkers of early response to trastuzumab. It is a prognostic factor study recruiting all consecutive cases of HER-2 positive breast cancer eligible for a pre-operative treatment by trastuzumab, followed by breast conserving surgery. The investigators will study the association between the value of biomarkers measured at diagnosis and the Response Evaluation Criteria in Solid Tumors response (partial and complete response) using a logistic regression (main analysis).
The ever expanding breast cancer survivor population urges the health care system to develop (cost-)effective screening and management of convalescent care needs that can be easily implemented in conventional follow-up care. Internet-delivered systems may be well-equipped to meet these demands. The aim of the current study is to assess the effectiveness of a web-based support system. Key features of this system are patient self-screening of physical and psychosocial problems, tailored patient education on reported problems and self-referral to professional care. In this era of high internet usage, we expect that internet is a highly suitable medium to provide tailored support for breast cancer patients and will empower the patient to take control over their convalescence.
Information about the presence of human epidermal growth factor receptor 2 (HER2) in tumor lesions in breast cancer patients is essential for diagnostic and therapeutic management of metastatic breast cancer. In daily practice however, obtaining a metastasis biopsy can be difficult or impracticable. Therefore, clinicians can be faced with a persistent clinical dilemma in some breast cancer patients, leading to suboptimal therapy decisions due to lack of HER2 receptor information. Circulating tumor cells (CTCs), which may provide additional information, have so far not been able to replace the biopsy. To solve this problem, non-invasive whole body visualization and quantification of HER2 expression by means of the HER2-PET may be a valuable tool. In this prospective multicenter imaging study, eligible patients will receive one HER2-PET and CTC analysis in addition to standard work up for metastatic disease. Subsequent administration of anti-HER2 therapy will be evaluated. Referring physicians fill in three questionnaires, one before HER2-PET and two after HER2-PET.
The Breast Cancer Surveillance Consortium (BCSC) database contains data from 1994-2009 on breast cancer screening, quality, and outcomes, and its main goal is to advance breast cancer research. This project is funded to maintain the BCSC database and share the data with investigators. Our objectives are to: - Maintain the BCSC pooled database using secure methods that protect the confidentiality of women, radiologists, facilities, and BCSC registries; - Encourage and facilitate sharing of BCSC research resources, and continue developing and implementing our communications plan to expand resource dissemination; - Provide statistical and scientific expertise to researchers, distribute customized limited datasets, and analyze BCSC data; - Develop and support a new web-based dynamic query tool and other electronic interfaces to efficiently share aggregated BCSC data with the public.
