Active clinical trials for "Breast Neoplasms"

The Orbis Paxman Hair Loss Prevention System is a new equipment introduced to Hong Kong in 2017. Although this device has been widely used in the United States, Europe and Australia, acceptability, efficacy and safety data in Chinese have not yet been available. The objective of this prospective study is to collect clinical data in Chinese patients using the Orbis Paxman Hair Loss Prevention System to prevent chemotherapy-induced alopecia. This project seeks to demonstrate that the Orbis Paxman Hair Loss Prevention System is safe and effective in reducing chemotherapy-induced alopecia in woman with breast cancer undergoing neoadjuvant or adjuvant chemotherapy.

Intraoperative Breast Radiation Therapy (IORT-Breast) utilizing the Xoft Axxent Electronic Brachytherapy System (Xoft) has been recently introduced as a treatment option for women 50 years of age and older who have early stage, low risk Invasive Breast Cancer (IBC). Clinical trials have shown IORT to be non-inferior to whole breast radiation, however some concern continues with rates of recurrence and clinical outcomes. Given the recent introduction and continued debate it is an excellent opportunity to observe and monitor outcomes in the patients that are treated at Navicent Health through this prospective, observational registry. The opportunity also permits examination of the participant's thoughts and feeling on Quality of Life and Cosmetic Appearance

The purpose of this study is to better understand how the immune system plays a role in fighting breast cancer and specifically research if the immune system response against breast cancer can be improved with endocrine therapy and cyclin dependent kinase inhibitor therapy in patients with hormone receptor positive breast cancer. This will be studied by collecting tumor tissue and blood samples before and after 2 weeks of study treatment with commonly used endocrine therapy and cyclin dependent kinase inhibitor therapy.

The objective of this study is to demonstrate the feasibility and acceptability of the algorithm utilized within a cancer rehab program, named Comprehensive Oncology Rehabilitation and Exercise (CORE) program, among newly diagnosed stage I-III breast cancer survivors, providers, and clinic staff. Additionally, this study aims to generate preliminary estimates on the extent to which CORE, compared with standard of care (SOC), elicits engagement in exercise and impacts changes in physical function and quality of life within this population.

This is a multi-center biomarkers study aiming to prospectively collect biological samples from patients with ER+ and HER2-negative metastatic breast cancer, who are candidate to first-line treatment with an aromatase inhibitor and a CDK4/6 inhibitor as per standard clinical practice. Blood and tissue samples will be collected for biomarker analysis, including thymidine kinase1 activity, gene expression signatures and circulating tumor DNA.

The investigators propose a randomized phase II clinical trial of talazoparib maintenance therapy in TNBC patients whose tumor showed clinical benefit (platinum-sensitivity) to first- or second-line platinum-based chemotherapy (monotherapy or combination with other agents). Patients are eligible when they meet at least one of two following platinum-sensitivity criteria: They should have received 6 tri-weekly doses or 18 weekly doses of platinum-based therapy in non-progression status (at least stable disease) at the time of enrollment; They should remain in complete or partial response status after 4-6 tri-weekly doses or 12-18 weekly doses of platinum-based chemotherapy. Eligible patients are enrolled to the trial within 4 to 8 weeks after last chemotherapy and 1:1 randomized to receive talazoparib versus placebo maintenance therapy. The primary endpoint is PFS by RECIST 1.1 after randomization. The secondary endpoints include OS, time from randomization to second progression or death (PFS2), and objective response rate (ORR) by RECIST 1.1, adverse events by CTCAE 5.0 criteria, quality of life evaluated by EORTC-QLQ-C30, and EuroQoL EQ-5D.

Circulating tumor DNA (ctDNA) offers the possibility of accessing the tumor genome from circulating blood through a simple blood test. It is currently used for diagnostic, prognostic and predictive purposes of response or resistance to oncological treatments. These advances in ctDNA have been made possible by major developments in molecular biology techniques in recent years, as the detection of ctDNA requires very sensitive techniques such as Next Generation Sequencing (NGS). CtDNA overcomes this problem of very limiting tumor heterogeneity during a solid biopsy. All of these applications make circulating DNA an increasingly essential tool in the management of cancer patients. The studies are currently in most cases on small numbers and are retrospective. In addition, exosomes are also a biomarker of the future that can also be detected in the bloodstream . Exosomes are nanovesicles 50 to 200 nm in diameter released into the extracellular environment via the endosomal pathway by fusion with the plasma membrane. They are very informative since they transport tumor genetic material in the form of DNA, mRNA and miRNA, but also adhesion proteins, immunostimulatory molecules and cytoskeleton, enzymes and Heats shock proteins ( HSP). The aim of the ADIGYN study is to set up a large prospective cohort to assess the diagnostic, prognostic and predictive impact of ctDNA and exosomes in digestive and gynecological / breast cancers. From the circulating DNA, we characterize the ActDNA on the molecular level thanks to the study of different point mutations usually used but also of new described mutations having a therapeutic impact and the search for other genetic alterations having an impact on the therapeutic strategy (such as microsatellite instability) or the study of exosomes and their composition. To assess resistance to oncological treatments, ctDNA will be analyzed at the start of treatment, during treatment, during progression and / or relapse and also during monitoring or treatment break

The purpose of this study is to train Nigerian radiologists to perform ultrasound-guided breast biopsies on women that present to the hospital with a suspicious breast mass. Before performing biopsies on patients, the Nigerian radiologists will have already successfully completed a competency-based mobile health ultrasound-guided breast biopsy-training program. This program, developed by experts in Nigeria and the United States of America, certifies that they have the skills required to safely perform these biopsies on patients.

It is planned to integrate various services based on computer vision technologies for analysis of the certain type of x-ray study into Moscow Unified Radiological Information Service (hereinafter referred to as URIS). As a result of using computer vision-based services, it is expected: Reducing the number of false negative and false positive diagnoses; Reducing the time between conducting a study and obtaining a report by the referring physician; Increasing the average number of radiology reports provided by a radiologist per shift.

Cardiomyopathy is a condition that affects the heart muscle, whereby it becomes enlarged, thick or rigid. When the heart muscle becomes involved, it affects the pumping action of the heart. This condition can affect as many as 10% of all patients after undergoing anthracycline cancer drug therapy and unfortunately carries the worst prognosis of all cardiomyopathies. To date, there is no effective intervention that will prevent a patient from developing this condition. The research conducted will look to see if an energy imbalance in the heart predates the onset of detrimental changes to the pumping function of the heart, if this is detected then we can act earlier to prevent the pumping function deteriorating.
