Filter by:The investigators propose to validate the utility of their novel hybrid imaging technique for accurate diagnosis of breast lesions, and for assessing chemotherapy response of cancer treatment and predicting treatment efficacy. The investigators' unique hybrid technique is implemented by simultaneously deploying near infrared (NIR) optical sensors and a commercial ultrasound (US) transducer mounted on a hand-held probe, and utilizing co-registered lesion structure information provided by ultrasound to improve the optical tomography. As a result, the optical tomography assisted with US has overcome problems associated with intense light scattering and has provided reliable tumor angiogenesis distributions. Initial results with a small group of patients who underwent biopsy have shown that early stage invasive cancers present two-fold greater total hemoglobin concentration on average than fibroadenomas and other benign lesions. Initial results of advanced cancers have shown that the angiogenesis distribution is highly distorted and heterogeneous, and the distorted distributions correlate with histological microvessel density counts and can be used to assess chemotherapy response. The objective of this study is to validate the investigators' initial results that NIR light guided by ultrasound can improve breast cancer diagnosis and monitor chemotherapy response.
Background: - Chemoprevention is the use of preventive medications to reduce the risk of breast cancer for women who are at a high risk of developing the disease. Although the treatment has shown effectiveness in preventing cancer development, chemoprevention is notably underutilized even by women who are at a high risk of developing breast cancer. - Researchers are interested in determining if better decision support mechanisms, such as interactive Web sites, can help to overcome some of the barriers to chemoprevention. Objectives: - To develop and test a prototype Web-based module that will provide decision support to women who are considering chemoprevention for breast cancer. Eligibility: - Women 35 years of age and older who are at high risk for breast cancer and whose doctor has recommended chemoprevention (either Tamoxifen or Raloxifene), and who have no other history of cancer (apart from non-melanoma skin cancer or precancerous cervical lesions). - Participants must have a working e-mail address and access to a computer with internet access and a telephone. Design: - Participants who are considering chemoprevention will be randomized to a Web-based decision support module or standard care online information resources. - Participation lasts two months and involves using the online resources provided and filling out questionnaires two times during the study (at the beginning and the end). The first time will be at the begin of the study. - No medical treatments are offered as a part of this study
The purpose of this study is to assess the impact of systematic "clinical cancer department/supportive care department" consultation meetings, versus standard care, on the prescription of an additional line of chemotherapy in patients with metastatic breast cancer and visceral involvement after 3 or 4 lines of chemotherapy. This is a prospective paucicentric open label randomized controlled study with 2 parallel arms. Eligible patients will be randomly assigned to either arm "Study group" or "Standard care". The number of patients required to demonstrate a 30% reduction of the number of prescriptions for an additional line chemotherapy, assuming an alpha risk of 5% and 80% power, is 100 (50 in each arm).
18F-FDG PET, a whole-body imaging technology based on glucose metabolism, can effectively detect subclinical and clinical therapeutic responses at stages that are earlier than those detected by conventional approaches. We propose to conduct a prospective study to evaluate early therapeutic response using 18F-FDG PET before and after the 1st cycle of neo-adjuvant chemotherapy for breast cancer patients. Variation of 18F-FDG PET uptake is compared to clinical and echographical tumor response evaluated after 3 cycles of chemotherapy. The purpose is to estimate the capacity of 18F-FDG PET to differentiate responder and non-responder patients.
Both the calcitriol and exercise interventions are aimed at reducing fracture risk by maintaining proper bone density, thereby preventing osteoporotic/osteopenic conditions and increasing muscle mass. Both calcitriol and exercise are efficacious in maintaining proper bone health and muscle mass among the general population, but little research has been done on breast cancer patients and survivors. The combination of calcitriol and exercise, which function through different but similar mechanisms, could produce interactive effects in reducing fracture risk among breast cancer survivors. Hypothesis: A combination of calcitriol along with a structured home-based walking and progressive resistance exercise program will be efficacious in preventing bone resorption and in increasing bone formation among survivors of invasive breast cancer.
RATIONALE: Mindful movement is a self-directed activity of mindfulness (intention, attention, and attitude) and physical movement. A mindful movement program may be effective in improving well-being in older women who are breast cancer survivors. PURPOSE: This randomized clinical trial is studying how well a mindful movement program works in improving quality of life in older female breast cancer survivors.
The purpose of this study is to determine the safety and tolerability of the combination of two drugs (letrozole and leuprolide) in women who have already taken tamoxifen for at least 4.5 years. Letrozole, an aromatase inhibitor (which blocks an enzyme that produces estrogen), is a drug that is FDA approved. It has been shown to reduce the risk of breast cancer recurrence in postmenopausal women with breast cancer who have been previously treated with tamoxifen. Letrozole works by stopping the production of estrogen in parts of the body other than the ovaries. Leuprolide is a drug that stops a women's ovarian cycles. This process is known as ovarian function suppression. Stopping a women's menstrual cycle may be effective against breast cancer for some patients when given as initial therapy. The combination of letrozole and leuprolide is considered a standard treatment for women with metastatic breast cancer, and is also sometimes used for treatment of premenopausal early stage breast cancer, but it has not been accepted as a standard of care treatment.
RATIONALE: Cranial microcurrent electrical stimulation (CES) is mild electrical current received through electrodes placed on the earlobes. CES may lessen symptoms in women with breast cancer receiving chemotherapy. It is not yet known whether CES is more effective than sham therapy in reducing symptoms caused by chemotherapy in women with breast cancer. PURPOSE: This randomized phase III trial is studying mild electrical stimulation to see how well it works compared with sham therapy in reducing symptoms caused by chemotherapy in women with stage I, stage II, or stage IIIA breast cancer receiving chemotherapy.
RATIONALE: Collecting information over time about patients' and health care providers' understanding of pain and fatigue and providing education about pain and fatigue management may improve quality of life. PURPOSE: This clinical trial is studying pain and fatigue management in patients with breast cancer, prostate cancer, colon cancer, or lung cancer.
The main purpose of this study is to determine if AZD8931 can improve the efficacy of standard chemotherapy for the treatment of advanced breast cancer. This study will be conducted in 2 parts: the first part (phase I) will determine a dose of AZD8931 that can be safely administered with paclitaxel chemotherapy. The second part (phase II) will determine the efficacy and safety of AZD8931 in combination with paclitaxel chemotherapy in breast cancer.
