Active clinical trials for "Breast Neoplasms"

Breast cancer is the most prevalent cancer affecting women, with 1 in 8 women in the UK developing breast cancer in their life time. Chemotherapy drugs, currently used for locally advanced breast cancers, are associated with side effects while dietary supplements have complex effects with a relatively small effect size. Breast tumours have different metabolism compared to healthy tissue, including elevated lactate production by aerobic glycolysis (AG), an underpinning feature of metabolism in breast cancer cells. Dietary nitrate, contained in leafy green vegetables and beetroot, has been shown to improve energy efficiency in exercising skeletal muscle, positioning itself as a disruptor of AG. The purpose of this study is to examine if dietary nitrate can disrupt AG and as a result to halt or even reverse tumour progression and survival. This study will look at scans of breast tumours using magnetic resonance imaging (MRI). Changes to tumour related biochemical substances will be measured by advanced magnetic resonance spectroscopy and changes to tissue structure will be measured by advanced diffusion MRI techniques. In this study, 16 patients undergoing surgery will be recruited for two MRI scans following a 5 day intervention programme.

This study is focused on the value of 18F-FES-PET in predicting the Fulvestrant efficacy in hormone receptor-positive breast cancer. The imaging agent involved in this study is 16α-[18F]-fluoro-17β-estradiol (18F-FES).

To test the effect of an individualized exercise oncology program on healthcare utilization, 30-day hospital readmission, pain, and cancer treatment tolerance.

The purpose of this study is to investigate the effect of providing information about radiotherapy using virtual reality and to see whether it would improve the productivity of medical staff, improve patient experience and satisfaction, and reduce patient's anxiety prior to radiotherapy.

The aim of this study is to evaluate the effects of rehabilitation robotics in upper limb functionality involved in the surgical treatment of breast cancer. The study will be conducted following the delineation of randomized clinical trial. It will be assessed 108 women aged between 30 and 60 years, submitted to surgical treatment of breast cancer and axillary dissection.

Breast cancer is the most prevalent cancer affecting women. To treat locally advanced breast cancers, neoadjuvant chemotherapy (NACT) is often carried out before surgery to reduce the tumour size to allow breast conservation surgery. However, treatment response for individual patients varies, where the tumour may not respond to treatment and the quality of patient care is compromised if the NACT treatment plan is not optimised. Therefore, the assessment of NACT efficacy is beneficial for the early identification of these patients and appropriate management of treatment. Breast tumours have unique features compared to healthy tissue, including abnormal tissue structure and biochemical composition. With NACT there are specific changes to such tumour features indicating tumour treatment response. The purpose of this study is to establish how the changes to breast tumour features following NACT treatment are seen in non-invasive imaging. This study will look at scans of breast tumours using magnetic resonance imaging (MRI). Changes to tissue structure will be measured by advanced diffusion MRI techniques and changes to tumour related biochemical substances will be measured by advanced magnetic resonance spectroscopy techniques. The investigators aim to assess if these techniques can provide information on the tumour treatment response following subsequent rounds of NACT treatment. In this longitudinal study, 25 patients undergoing NACT will be recruited for four repeated MRI investigations over the course of NACT treatment. Magnetic resonance (MR) measurements of tissue microstructure and biochemical composition will be compared against histological measurements and radiological assessments of treatment response. The study will recruit patients undergoing treatment at the NHS Grampian. This research is funded by Friends of ANCHOR, Tenovus Scotland Grampian and the NHS Grampian Endowment Research Fund.

Breast cancer (BC) survivors will experience multiple symptoms following chemotherapy. During the pandemic of COVID-19, the closure of clinics and fear of infection lead to BC patients' challenges in self-managing their multiple symptoms in home settings. Mobile health (mHealth), without time and space limitation, plays a positive role in supporting self-management and treatment compliance. However, previous mHealth self-management studies did not report sustained beneficial effects with physician-led supervision. In oncology practice, the nurse-led model of patient self-management for breast cancer has been placed on greater emphasis. Accordingly, an innovative nurse-led supervised mHealth program was designed to support self-management for BC patients undergoing chemotherapy. This pilot study aims to examine the feasibility and acceptability of a nurse-led mHealth-based self-management program for BC patients receiving chemotherapy, in order to provide evidence for conducting a definitive trial. The feasibility outcomes of the pilot study include subject eligibility rate, recruitment rate, and retention rate. The efficacy outcomes relate to self-efficacy (primary outcome), symptom distress and frequency, as well as health-related quality of life, and healthcare utilisation. The qualitative outcomes encompass patient- and provider-users' perceptions of the app usability and subjects' experiences of engaging in the pilot study.

Background of the study: Breast cancer is the most prevalent cancer in Dutch women. Adjuvant endocrine therapy (AET) substantially improves chances for survival after primary breast cancer. In practice, many women experience difficulties to adhere to treatment: besides missing single or multiple doses of medication, up to 50% of patients stop treatment prematurely due to decreased treatment motivation over time and burden of side effects. Together with patients and health care professionals, we adapted a cost-effective behavior change intervention (AIMS) for women using adjuvant endocrine therapy after breast cancer to an add-on module in regular follow up care. Objective of the study: The primary aim of this study is to pilot test the feasibility of the AIMS-AET intervention versus usual treatment on medication adherence in breast cancer survivors on adjuvant endocrine therapy. Intervention effects on psychosocial determinants and user experiences will be evaluated. The feasibility of testing the AIMS-AET intervention in a bigger RCT will be assessed. The secondary objective is to assess (preliminary) intervention effects on adherence, physical activity and on quality of life. Study design: A pilot randomised controlled trial comparing AIMS AET to usual care with an extensive mixed-methods process evaluation. Study population: Female outpatients of 2 Dutch hospitals with a prescription for adjuvant endocrine therapy after primary breast cancer. Intervention (if applicable): An in-person delivered intervention imbedded in regular follow-up care during 9-months. Patients will receive an electronic monitoring System to track medication intake and a pedometer to count daily amount of steps. During the baseline visit, the health care professional (HCP) will use pre-tested materials for informing and motivating patients; and collaboratively set goals and plans for medication adherence and physical activity. During regular follow-up consultations with the HCP, personalized visual reports of medication intake and amount of steps will be evaluated to enhance patients awareness of their (non-)adherence and (in)activity and identify any problems and solutions to reduce undesired behaviour. The control group will receive usual treatment only.

This is a monocentric cohort study, prospective and interventional with minimal risks and constraints for advanced breast cancer. The planned interventions are collection of biological samples at different times. The study will aim to do a descriptive analysis of omics profiles evolution (tumor, volatile organic components) over time, before and after disease progression under Palbociclib treatment with a clinical-biological database.

Surgical samples of human primitive breast: Representative and various surgical samples of human primitive breast carcinoma in terms of histological type. Moreover, healthy tissue from the same patient will be analysed in parallel. Adjacent normal epithelial structures will be defined as at least 5 mm away from the tumor and histologically normal in appearance. Isolation, differentiation of human monocyte-derived Macrophages (Mphs) and determination of the Macrophage (Mph) migration mode : Human Mphs will be differentiated from blood monocytes isolated from the same patient than the tumor sample. Blood samples will be obtained following standard ethical procedures.
