Active clinical trials for "Breast Neoplasms"

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.

This study evaluates vaginal microbiome as a biomarker to improve vaginal and sexual health in women with breast cancer receiving endocrine therapy. Breast cancer is the most common cancer in United States women, aside from skin cancers. Endocrine therapy is standard treatment for 70% of invasive breast cancers, significantly affecting sexual health and often causing women to change their course of treatment or cease sexual activity. Changes in the vaginal microbiome, which is the collection of all microorganisms, such as bacteria, fungi, and viruses, that naturally live on and inside the body, are implicated in menopausal-related sexual health symptoms, but the vaginal microbiome (and associated immune responses) has not been explored as a biomarker for sexual health changes in hormone-related sexual health symptoms in breast cancer. A biomarker is a biological molecule found in blood, other body fluids, or tissues that is a sign of a normal or abnormal process, or of a condition or disease. Ribonucleic acid (RNA)-sequencing is a cost-effective method to analyze both human and microbial transcripts. The RNA that is sequenced from a standard biological sample such as a swab is a snapshot of the expression of many different cells and can be used to simultaneously measure the quantities of microbes, the overall expression of the human host, and the quantities of immune cells. Information gathered from this study may help researchers establish the vaginal microbiome as a biomarker and therapeutic target to improve the vaginal and sexual health of women with breast cancer receiving endocrine therapy.

This study will evaluate the safety and efficacy of trastuzumab deruxtecan (T-DXd) in participants with human epidermal growth factor receptor 2 (HER2)-low or HER2 immunohistochemistry (IHC) 0 (who are both hormone receptor [HR]-negative and HR-positive) unresectable and/or metastatic breast cancer.

Breast surgery may be overtreatment when there is a complete response to systemic neoadjuvant treatment as determined clinically and by imaging. However the reliability of imaging techniques (ultrasound, mammography and magnetic resonance) in identifying complete response varies in published studies and surgery remains the preferred method of detecting residual disease. The aims of this study are: To assess the reliability of minimally invasive preoperative image-guided vacuum-assisted biopsy (VAB) in identifying residual breast in cT1-cT2-cT3, cN0-cN1 breast cancer patients, either with complete clinical/radiological response, or with residual breast disease <1 cm, after systemic neoadjuvant treatment. To assess the reliability of minimally invasive preoperative image-guided needle biopsy in identifying residual axillary disease in cT1-cT2-cT3, cN0-cN1 breast cancer patients, either with complete clinical/radiological response, or with residual breast disease <1 cm, after systemic neoadjuvant treatment. After neoadjuvant treatment, and evaluation with ultrasound, mammography and magnetic resonance, VAB will be performed on the breast, and needle biopsy will be performed on the axillary lymph node of pre-treatment cN1 cases, previously marked with a magnetic clip. The biopsy findings will be compared with the surgical findings, consisting in quadrantectomy or mastectomy plus sentinel node biopsy (or separate removal of tagged lymph nodes if they do not coincide with the sentinel node(s)) to assess the ability of biopsy to identify residual disease.

This is an open-label, multicenter, phase II study to evaluate the efficacy, safety, tolerability, pharmacokinetics of the combination of tucatinib-Oral VP16-trastuzumab in patients with HER2-positive metastatic breast cancer (HER2+ MBC) after progression on tucatinib-capecitabine-trastuzumab or capecitabine-related toxicity.

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.

This study aimed to evaluate the efficacy and safety of Dalpiciclib combined with Letrozole in the maintenance treatment of HR positive and HER2 negative metastatic breast cancer after first-line chemotherapy.

This phase II trial investigates how well 177Lu-DOTATATE works in treating patients with breast cancer that is stage IV or has come back (recurrent). 177Lu-DOTATATE may shrink or destroy the tumor or circulating breast cancer stem cells if they show evidence of the SSTR2. 177Lu-DOTATATE is a targeted therapy that uses DOTATATE, linked to a radioactive agent called 177Lu. DOTATATE attaches to tumor cells with SSTR2 and delivers 177Lu to kill them. Giving 177Lu-DOTATATE may help decrease the number and size of tumors and the number of circulating cancer stem cells in patient's blood for the treatment of patients with breast cancer positive for SSTR2.
