Active clinical trials for "Breast Neoplasms"

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. Deslorelin combined with low-dose add-back estradiol and testosterone (given to replace hormones suppressed by deslorelin) may be effective in preventing breast cancer in at-risk women. PURPOSE: This phase II trial is studying how well giving deslorelin together with estradiol and testosterone works in preventing breast cancer in premenopausal women who are at high risk for this disease.

The purpose of this study is learn more about how being treated for breast cancer affects patients' employment. Researchers are testing an early version of a mobile app designed to help breast cancer patients keep their jobs during and after treatment. The app provides advice for patients to use when having conversations about breast cancer with their employers and their doctors. The app is called TEAMWork (Talking to Employers And Medical staff about Work). In this study, the investigators are asking breast cancer patients who are about to receive treatment or who are currently receiving treatment to tell us what aspects of the app work well, so that they can learn how to improve it.

The Southeast Netherlands Advanced Breast Cancer (SONABRE) Registry is a real life multi-center study. The registry aims to include all patients diagnosed with advanced breast cancer as of 2007 in 11 hospitals in the Netherlands. Data on patient, tumor and treatment characteristics are collected retrospectively from electronic medical files by trained registry clerks.

This trial studies histamine and bone pain association in participants with breast cancer that has spread to the bone. Studying histamine levels in samples of blood from participants with breast cancer in the laboratory may help doctors learn more about reducing cancer bone pain and preventing further bone metastasis.

Basis: Brain metastasis is very common in breast cancer, and HER2 positivity is a risk factor for high incidence of brain metastasis, with approximately 50% of HER2+ MBC cases experiencing brain metastasis. The reason for this is that as the efficacy of HER2-targeted therapy improves, the survival of these patients significantly extends, leading to an increase in the occurrence rate of brain metastasis events in the late stage of MBC. In the systemic treatment of HER2+ breast cancer brain metastasis, various HER2-targeted drugs have been explored, but none have achieved satisfactory therapeutic effects. Therefore, it is imperative to explore new treatment options. ADC drugs have shown some efficacy in brain metastasis patients, and as a domestically developed ADC drug, trastuzumab vedotin has demonstrated good anti-tumor effects. The treatment model combining trastuzumab vedotin with small molecule TKIs has been rarely reported, so we are attempting to use the treatment model of trastuzumab vedotin combined with pyrotinib or neratinib to explore its efficacy and safety in patients with HER2-positive brain metastasis. Method: The plan is to recruit HER2-positive breast cancer patients with brain metastasis and use the treatment of trastuzumab vedotin combined with pyrotinib or neratinib (specific treatment drugs to be selected during the study). Procedure: All subjects will undergo screening, treatment, and follow-up periods, strictly adhering to relevant GCP regulations during the treatment process. Expectations: Through this study, preliminary efficacy and safety data of trastuzumab vedotin combined with pyrotinib or neratinib treatment will be provided for patients with HER2+ brain metastatic BC.

This prospective study recruits patients with ER+/HER2-, non-metastatic breast cancer who omit upfront surgery in favor of primary endocrine therapy for sample collection and prospective circulating tumor DNA (ctDNA) measurement to guide disease surveillance.

Returning to and maintaining employment after cancer is essential for restoring social participation, financial independence and reducing the social costs associated with cancer. Many obstacles that prevent or delay the return to work have been identified. They are associated with the consequences of the disease and treatments such as fatigue, pain and cognitive disorders, the lack of collaboration between health professionals (oncologists, general practitioners and occupational physicians), and the characteristics of the environment. in terms of the demands of the job, and the (lack of) social support from superiors and colleagues. There are social inequalities in the return to work after cancer, with a poorer professional prognosis among older and less qualified people. Social inequalities linked to ethnicity have been documented in other countries. In France, 58,500 new cases of breast cancer are diagnosed each year, half of them in women of working age. The importance of job retention has been formalized in the objectives of the latest cancer plans, and in the 2018-2022 national health strategy. Initiatives are observed to promote this issue by employers: development of a charter by the National Cancer Institute and in the associative field aimed at promoting support practices in their professional environment for people with cancer. Despite the development of descriptive knowledge on prognostic factors for returning to work after cancer, the results of interventional studies are mixed. No intervention has been shown to be effective in facilitating return to work and reducing social disparities in employment after breast cancer. Interventions have been criticized for being too medicalized and lacking a sufficient theoretical basis to analyse causes (theory of the problem) and propose solutions (theory of action). The "FASTRACS" intervention was developed with the Intervention Mapping protocol to facilitate the return to work after breast cancer, it defines a return-to-work path from the hospital to the company through care primaries. This intervention is anchored in primary care with an early transition consultation in general medicine in the month following the end of active treatments (chemotherapy or radiotherapy according to the care protocol). This positioning in primary care allows a bio-psycho-social assessment of the needs of women after cancer. This consultation was designed to establish a plan of care and return to work according to the temporality and individual needs of each woman. It will make it possible to determine the right time for the pre-recovery visit in order to anticipate the professional challenges of the recovery. Return to work/maintenance in employment interventions are complex social interventions, implemented by social actors who act in an environment with which they interact. These interventions (or programs) present an increased risk of failure in their implementation and sustainability. Realistic evaluation comes from the trend of theory-based evaluation (theory-based or theory-driven evaluation). According to this approach, social interventions are based on theories, which can be tested through empirical observation to better understand how and why they produce their effects, and in what context. This approach overcomes the limits of the "black box" model. It is recommended to inform the public decision to interrupt, modify or intensify an intervention. It aims to answer the question: "what works, how, why, for whom, and under what circumstances?" ". It aims to describe the mechanisms of the effectiveness of an intervention by linking its effects to the characteristics of its implementation context (search for CME configurations = context - mechanisms - effects). The search for these configurations, otherwise called "half-regularities" because they can be observed empirically with certain variations, is intended to develop a middle-range theory with a sufficient level of generalization and abstraction. to explain the tendencies and the regularities observed in the interactions contexts-mechanisms-effects of the intervention. This approach is particularly indicated in the evaluation of the FASTRACS intervention, given the complexity of the intervention, the number of actors involved, and the variety of its implementation contexts.

Patients with stage II-III Triple negative breast cancer (TNBC) candidates to receive neoadjuvant chemotherapy (NACT) +/- immune checkpoint inhibitor (ICI) will be included. Several samples from different tissues will be analyzed through different omics to establish predictive biomarkers of response to the treatment. Multiple algorithms will then be used to look for an integrative predictive algorithm that incorporates multi-parameter inputs in order to develop a clinical tool to assist clinicians in the process of treatment decision-making in TNBC.

This phase Ib/II trial tests the safety, best dose and how well gemcitabine and ex vivo expanded allogenic universal donor TGFBi NK cells with or without naxitamab work for the treatment of patients with GD2 expressing, HER2 negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Gemcitabine is a chemotherapy drug that blocks the cells from making deoxyribonucleic acid (DNA) and may kill cancer cells. TGFBi NK cells are manufactured cells that are a part of your natural immunity. NK cells can recognize missing or incorrect proteins on tumor cells and then eliminate these tumor cells and TGFBi NK cells are created to be able to better kill the tumor cells. Naxitamab is a monoclonal antibody that targets GD2, which is a protein or sugar present on tumor cells but not very commonly found on normal cells. This antibody helps draw the attention of the immune system to the tumor cells that have GD2 to help attack the tumor cells. Giving gemcitabine and TGFBi NK cells with or without naxitamab may kill more tumor cells in patients with metastatic GD2 expressing, HER2 negative breast cancer.

The goal of this clinical trial is to evaluate the efficacity and safety of pembrolizumab and capecitabine compare to pembrolizumab alone, on the invasive disease-free survival, in participants who have triple negative breast cancer (TNBC) with residual disease after neoadjuvant chemotherapy associated with pembrolizumab.
