Filter by:Proposed is a 6-month randomized controlled trial, in 200 overweight or obese Stage I-IIIC breast cancer survivors examining 6-month changes in: 1) body weight, 2) diet, 3) physical activity, and 4)quality of life in women randomized to receive the modified LEAN intervention compared to women randomized to wait-list control (i.e., the wait-list control will receive the modified LEAN intervention after completing the 6-month study).
The sensitivity and specificity of uPAR PET/CT for preoperative detection of lymph node metastases in breast cancer.
Treatment selection for breast cancer is still largely empiric and guided by large randomized clinical trials on populations of patients. This approach is inadequate for the selection of individualized chemotherapy regimens. Estimates of benefits for individuals are extrapolations from the effects seen in these large trials, and do not necessarily apply to individual patients. The revolution in genomics promises to transform oncology care. By better defining cancer subtypes, a better understanding of breast cancer biology should help to guide treatment. The up-front phase we have decide to adopt play a pivotal role as it is useful for testing a targeted therapeutic drug such as olaparib wich also requires development of new biomarkers which may be useful for future studies. With this approach it could be possible to demonstrate drug target or biomarker effect in clinical setting and models the relationship between the pharmacodynamics and the pharmacokinetics. Additional benefits of this approach include the following: - It could facilitate rational drug selection, identify therapeutic failures early, and compress timelines for anticancer drug development. - It could provide initial rationale and guiding principles for further drug development based on studies in humans (rather than xenografts, where tissues of one species are transplanted to another species). - As it focuses on extensively characterizing how a drug works and whether it hits its intended target (including molecular imaging studies) in a limited number of patients it could yield results that would optimally inform and expedite the subsequent development of molecularly-targeted agents
A single centre, single arm phase II study of alternating eribulin and hormonal therapy in 12 patients with locally advanced or metastatic breast cancer who have received at least one hormonal therapy and at least one chemotherapy in the metastatic setting.
This is a pilot, non-randomized, single institution, observational study investigating the effect of dramatic weight loss secondary to bariatric surgery on biomarkers of breast cancer in tissue and blood as well as on imaging in women at elevated risk for breast cancer. Twelve months after bariatric surgery, 50% of excess weight is generally expected. Eligible women at elevated risk for breast cancer who are already planning to undergo bariatric surgery will be consented to undergo imaging (MRI and mammogram), breast tissue biopsy, and fasting blood draw prior to bariatric surgery, approximately 14 days after bariatric surgery, and approximately 1 year after bariatric surgery. In parallel we will also be assessing 40 normal breast tissue specimens as well as blood samples from the Komen Tissue Bank (elevated risk but normal BMI) to establish a normal BMI, elevated risk control group for our study. The KTB samples will be matched for general risk of breast cancer (>20%), age, race and menopausal status.
This study will test the safety of partial breast RT using 27Gy in 5 daily fractions which is expected to be equally tolerated as standard whole breast irradiation (WBI) based on radiobiologic modeling of the fibrosis response of normal tissues but be more convenient and less costly than 3-6 weeks of standard WBI. 274 women will be treated. Rates of fibrosis and cosmesis at 2 years will be compared to data already collected using standard WBI in the Canadian RAPID trial.
In low-risk node-negative breast cancer patients adjuvant chemotherapy should be spared. The identification of this subgroup can be based either on clinical and pathological or on tumour-biological criteria. Due to their high prognostic impact, the tumour-biological invasion markers uPA/PAI-1 (urokinase-type plasminogen activator and its inhibitor PAI-1) are potential candidates to effectively assess the risk of relapse in node-negative breast cancer. This study is aimed to compare the risk assessment by the traditional clinico-pathological factors and by tumour-biological factors. The second study question refers to the comparison between an adjuvant combination treatment with FE100C*6 and a sequential treatment with FE100C*3 and Docetaxel*3.
A study of palbociclib in combination with letrozole as treatment of post-menopausal women with hormone receptor-positive, her2-negative advanced breast cancer for whom letrozole therapy is deemed appropriate.
A Multi-center Cross-sectional quantitative study with a preliminary qualitative study part aiming to identify and analyze demand factors, supply factors and perceptions affecting Breast Cancer patients' treatment choices of Breast Cancer patients in 5 key decision points: participation role in the decision making process, hospital choice, treatment regimen choice, surgical extent and surgeon choice. 25 patients and caregivers will participate in the qualitative part and 425 Israeli Breast Cancer patients will participate in the quantitative study.
This is a single-arm, single-institution pilot study that will collect preliminary data to be used in the design of a subsequent study to assess whether changes in fDM (Functional Diffusion Maps) derived from primary breast cancer diffusion weighted MRI images can serve as an early predictor of response to treatment, and whether the magnitude of the change correlates with the effectiveness of treatment.
