Active clinical trials for "Breast Diseases"

Prospective, observational cohort study looking at patients either at risk of breast cancer or have clinically suspected breast to assess the diagnostic performance of quantitative, non-contrast MRI.

Breast cancer incidence is increasing in low- and middle-income countries (LMICs) and breast cancer mortality is high in these regions largely due to late stage diagnoses. This is true in the low-income East African country of Rwanda, where there are no national protocols in place to guide evaluation and referral of breast symptoms at primary health facilities. This study will use quantitative and qualitative methods to examine implementation of the Women's Cancer Early Detection Program (WCEDP) in order to understand optimal strategies to scale and sustain breast cancer early diagnosis in Rwanda and other limited-resource settings. The WCEDP is an adaptation of a prior intervention in Burera District, which focused on building community awareness of breast symptoms, improving clinicians' clinical breast assessment (CBA) skills, and implementing weekly breast clinics at the primary health care center and hospital levels. The Burera intervention was associated with improvements in health care workers' knowledge and skills, increases in care-seeking and receipt of care by women with breast symptoms, and an increase in early-stage breast cancer diagnoses.

The VITamin D and OmegA-3 TriaL (VITAL; NCT 01169259) is an ongoing randomized clinical trial in 25,875 U.S. men and women investigating whether taking daily dietary supplements of vitamin D3 (2000 IU) or omega-3 fatty acids (Omacor® fish oil, 1 gram) reduces the risk of developing cancer, heart disease, and stroke in people who do not have a prior history of these illnesses. This ancillary study is being conducted among participants in VITAL and will examine whether vitamin D effects mammographic breast density, mammographic texture features, and gene expression profiles in breast biopsy tissue.

The goal of this observational study is to compare the image differences between conventional ultrasound and artificial intelligence-based ultrasound software in conscious adults. The main question it aims to answer is to evaluate the effectiveness by determining that the new image analysis method is considered valid if it helps to identify more than 30% of histological characteristics. Participants will undergo the examination using the two methods mentioned earlier after signing the consent form.

Breast cancer is the most commonly cancer in women in the overall global population. According to the World Cancer Research Fund International, there were more than 2.25 million new cases of breast cancer in women in 2020. Although the modern treatment strategies, based on the complex care, which consists of surgery, radiotherapy, hormone therapy, and targeted chemotherapy directed at specific cancer molecules have substantially reduced the risk of death due to breast cancer, their wide adoption results in the wider prevalence of cardiotoxicity, defined as either symptomatic heart failure, or asymptomatic contractile dysfunction. The occurrence of cardiotoxicity induced by anti-cancer therapies is estimated at 5-15%, and its development is the primary cause of therapy termination, which significantly reduces the probability of the efficacy of treatment. Several attempts have been made to determine the efficacious preventive strategy, which could diminish the risk of cancer-therapy induced cardiotoxicity. The results of the prior studies indicated a trend towards lower risk of troponin elevation, or left ventricular contractile dysfunction with the introduction of drugs interfering with the renin-angiotensin-aldosterone (RAA) axis, which constitute the primary treatment modality in heart failure with reduced ejection fraction (HFrEF). Sacubitril/valsartan, the novel therapeutic agent, has been demonstrated to significantly improve prognosis in patients with HFrEF. Prior retrospective, small, single-center studies have shown that treatment with sacubitril/valsartan may reduce the risk of cancer-therapy induced cardiotoxicity, or reverse contractile dysfunction caused by anti-cancer therapy. However, no large randomized data confirmed these findings. Therefore, the Sacubitril/Valsartan in PriMAry preventIoN of the cardiotoxicity of systematic breaST canceR trEAtMent) study, has been designed to verify, whether the preventive use of sacubitril/valsartan administered in the doses recommended in patients with HFrEF in breast cancer patients undergoing adjuvant chemotherapy with anthracyclines or anthracyclines and HER-2 monoclonal antibodies, will reduce the incidence of cardiotoxicity defined as impaired left ventricular systolic function on cardiac magnetic resonance imaging (MRI). In the trial, a total of 480 patients with histologically confirmed breast cancer, who are eligible for chemotherapy with anthracyclines or anthracyclines and HER-2 monoclonal antibodies, will undergo 1:1 randomization to either preventive treatment with sacubitril/valsartan or placebo. The patients will be followed for 24 months, and will have repetitive efficacy and safety examinations, including echocardiography, MRI, electrocardiography including 24-h Holter monitoring, blood tests, functional capacity tests and quality of life assessment.

This is an observational, prospective, and transversal study, designed to evaluate the effectiveness of CELBREA® in women from the local community coming to consult at the Breast Pathology Unit of La Paz Hospital (Madrid, Spain), because of discomfort, breast symptoms, or because they have been sent for specialized evaluation because of a diagnostic doubt, providing actualized data on the effectiveness of the device within the context of the real-world scenario. Because of its transverse nature, the observation period will be limited to the necessary amount of time to perform the initial consult, additional tests when prescribed by the physician, and the CELBREA® test.

Nipple-sparing mastectomy (NSM) with immediate reconstruction is one of the standard of care surgical treatments of breast cancer (BC) and is used for risk reduction in patients with a high risk for BC. While this method shows satisfactory oncologic and good cosmetic outcomes, its drawbacks include compromise of the skin flap vascularization due to skin incision, nipple-areolar complex (NAC) malposition/distortion and visible scar on the breast. NSM also has technical challenges of dissecting and removing larger specimens through limited incisions and concerns regarding oncologic effectiveness due to difficulties in visualizing regions of the breast remote from the incision. To improve cosmetic outcomes after NSM, a modification of this technique using a surgical robotic system was recently described. In a limited number of studies, the robotic NSM (RNSM) with immediate prosthetic breast reconstruction (IPBR) was shown to be feasible and safe, as well as led to excellent cosmetic outcomes and patient satisfaction. There are limited number of centers in North America and none in Canada that offer RNSM-IPBR. The investigators hypothesize that RNSM-IPBR is a feasible and safe technique that can be utilized in our institution and that it can provide superior cosmetic outcomes with less morbidity and higher patient satisfaction compared to the traditional NSM-IPBR. The aim is to conduct a single-arm prospective study to investigate the safety and feasibility, as well as cosmetic, surgical complication and patient satisfaction parameters of NSM-IPBR performed in the University Health Network (UHN). This study will serve a foundation for potential introduction of a novel surgical approach in our institution and will make it available for treatment and prevention of breast cancer in Canadian women. The study will also serve as pilot data for future potential studies, including randomized-controlled trials (RCT) comparing RNSM with conventional NSM. As such, the study will further our approach to innovation in breast surgical oncology within Canada and North America.

A standard of truth "SOT" is determined based on the interpretation results of the case data by interpretation experts, and the SOT is compared with the detection results of this program's function for detecting suspected breast cancer (CADe function). Estimate the detectability of the CADe function by comparing.

Tissue elasticity is being increasingly used as diagnostic parameter, since at the macroscopic level benign breast lesions tend to be stiffer than normal breast tissue but softer than breast cancers. Ultrasound elastography allows to probe the elasticity of breast lesions in clinics. Real time elastography (RTE) and shear wave elastography (SWE) are the two most widely used elastography modalities. Assessment of breast lesions by either RTE or SWE improve the diagnostic performance of standard B-mode ultrasound (US) and have the potential to assist the decision about whether to perform a breast biopsy or not.

The Breast Cancer Program Longitudinal Repository (BCPLR) is being established to fulfill the research mission of the Breast Cancer Program at Johns Hopkins and to serve investigators affiliated with it - to develop a repository of specimens with corresponding characteristics from patients seen in the breast care and cancer clinics.
