Active clinical trials for "Breast Neoplasms"

To evaluate the patterns and treatment outcomes of pyrotinib plus vinorelbine in the real world.

To evaluate the efficacy and safety of Eribulin in patients with advanced breast cancer.

Axillary lymph nodes are the main site of metastasis in breast cancer. If positive axillary lymph nodes are present, an axillary lymph node dissection (ALND) is usually performed. This procedure improves disease-free survival but comes with the risk of lymphoedema as a result of disrupted lymphatic channels. Breast cancer-related lymphoedema (BCRL) is associated with considerable morbidity, which is why proven measures to reduce its incidence would improve patient outcomes. We aimed to investigate whether a regime of manual lymphatic drainage and exercise, supervised by a manual lymphatic drainage therapist compared to standard care would reduce the incidence of breast cancer-related lymphoedema in patients undergoing ALND.

Most studies of cancer stem cells (CSC) involve the inoculation of cells from human tumors into immunosuppressed mice, preventing an assessment on the immunologic interactions and effects of CSCs. In this study, the investigators examined the vaccination effects produced by CSC-enriched populations from histologically distinctmurine tumors after their inoculation into different syngeneic immunocompetent hosts. Enriched CSCs were immunogenic and more effective as an antigen source than unselected tumor cells in inducing protective antitumor immunity.Immune sera from CSC-vaccinated hosts contained high levels of IgG which bound to CSCs, resulting in CSC lysis in the presence of complement.CTLs generated from peripheral blood mononuclear cells or splenocytes harvested from CSC-vaccinated hosts were capable of killing CSCs in vitro. Mechanistic investigations established that CSC-primed antibodies and T cells were capable of selective targeting CSCs and conferring antitumor immunity.

This study is being done to see if the investigators can measure changes that occur in breast tissue when women at risk of developing breast cancer start an exercise program. The investigators are interested in studying this because research shows that women who exercise regularly are less likely to develop breast cancer, but there is not very much information explaining how exercise could affect breast cells in a way to prevent cancer from occurring. In this research study the investigators will use a research technique called breast random fine needle aspiration (RPFNA) to test breast cells for their shape and how they look. The investigators will look at breast cells before and after a participant takes part in an exercise program to see if the investigators are able to see any changes in breast cells that could have happened due to the exercise program. This research will help us to develop larger projects to see if exercise programs could be helpful in preventing breast cancer.

The investigators will determine which factors are predictive for the development and severity of everolimus-induced interstitial lung disease and will develop a prediction model based on these risk factors.

In order to evaluate the late outcome in patients curatively treated for breast cancer, a special outpatient clinic will be developed. There are two main purposes of the outpatient clinic. The first purpose is evaluating the results of the radiation treatment by mapping A) late toxicity and B) tumour control and survival. The second purpose is that this outpatient clinic for late outcome will also function as a pilot for a new CAT (Computer Assisted Theragnostics, abbreviated CAT project) in which multiple late outcome variables will be recorded. In this pilot we want to investigate whether physical presence of the patient on the outpatient clinic, allowing physical examination, has any added value to the questionnaires filled in by the patient at home. The ultimate aim of this new CAT project is to use these multicentric data to develop models for predicting both oncological outcome and late side effects. Insight in the beneficial and adverse effects of a certain treatment using these predictive models, will be required choose the optimal treatment for the individual patient using a shared decision making process.

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).

AIM To determine the value of trastuzumab in the early breast cancer setting in the Netherlands. RESEARCH QUESTIONS / OBJECTIVES Is adjuvant trastuzumab in daily practice effectively used, that is, how and to whom is it given? Is the introduction of trastuzumab in early breast cancer cost-effective for the Netherlands? To address the research questions (objectives), the following outcome measures will be determined: CLINICAL OUTCOME MEASURES Actual trastuzumab administration as opposed to planned trastuzumab administration Selection criteria for chemotherapy and trastuzumab in daily practice Immediate and longterm toxicities due to adjuvant treatment, specifically cardiac Disease-free, breast cancer specific, and overall survival in relation to trastuzumab ECONOMIC OUTCOME MEASURES Volumes and costs of diagnostic tests and therapies including those for (distant) relapse Cost-effectiveness of trastuzumab in clinical trials versus in real world

Early stage hormone receptor positive breast cancer is typically treated with adjuvant endocrine therapy in order to decrease risk of breast cancer recurrence and to improve overall survival from the disease. Typical agents used for treatment include tamoxifen and the aromatase inhibitors. In postmenopausal women, aromatase inhibitor therapy is increasingly common because it is associated with fewer long-term serious toxicities compared to tamoxifen. However, aromatase inhibitors cause arthralgias in 40-50% of patients, which can influence adherence to therapy and can lead to treatment discontinuation in a minority of cases. The mechanism underlying development of this toxicity remains unclear, and predictors of who will develop these symptoms remain undefined. Initial reports suggest that grip strength decreases during aromatase inhibitor therapy, and that body-mass index may influence development of this symptom. Therefore, this longitudinal study has been developed to determine change in grip strength over time in women treated with aromatase inhibitors and tamoxifen, as well as to identify potential associations between change in grip strength and BMI. Patient self-reported symptoms will also be collected. A total of 115 women with early stage breast cancer who are initiating therapy with either an aromatase inhibitor or tamoxifen will be enrolled.
