Filter by:The goal of this observational study is to investigate the ability of a the Z-scanner to identify and differentiate cancer and benign lesions from healthy breast tissue based on permittivity. The main questions it aims to answer are: 1. Determine the permittivity values of the Z-scanner associated with healthy, benign, and malignant tissue in human breasts. 2. Determine the repeatability, reproducibility, inter-and intra-operator variability of the Z-scanner.
The accuracy of breast examinations and ultrasonography performed clinically to detect breast mass varies greatly depending on the physician's skill level, and the accuracy of breast examinations by non-experts is particularly low. In this study, we aimed to validate whether the concurrent use of ultrasound sensor technology is an efficient strategy for the purpose of improving the sensitivity of detecting breast masses through breast examination.
The overall aim of the project is to investigate how artificial intelligence (AI) can be used to streamline and at the same time increase diagnostic safety in breast cancer screening with mammography. AI has been shown in a number of studies to have great potential for both increasing diagnostic certainty (e.g. reduced occurrence of interval cancers) and at the same time reducing the workload for doctors. However, much research remains to clinically validate these new tools and to increase the understanding of how they affect the work of doctors. The specific goal of the project is to investigate whether the implementation of AI in breast cancer screening in Östergötland, Sweden, can increase the sensitivity (the mammography examination's ability to find breast cancer) and the specificity (that is, the right case is selected for further investigation: a minimum of healthy women are recalled but so many breast cancer cases that are possible are selected for further investigation) and at the same time make screening more efficient through reduced workload. AI will be implemented in the clinical routine and performance metrics such as cancer detection rate etc will be closely monitored. The study do not assign specific interventions to the study participants.
Regional techniques can be used for postoperative pain control following breast surgery. Ultrasound (US) guided serratus posterior superior block (SPSPB) is a new interfacial plane block defined by Tulgar et al in 2023. It is based on injection on the serratus posterior superior muscle at the level of the 2nd or 3rd rib. This block provides analgesia in conditions such as interscapular pain, chronic myofascial pain syndromes, scapulocostal syndrome, and shoulder pain. The SPS muscle is located at the C7-T2 level. It attaches to the lateral edges of the second and fifth ribs. It is innervated by the lower cervical and upper intercostal nerves. With the SPS block, these nerves are blocked and analgesia is provided.
SOLUS is a trans-disciplinary 48-month project bringing together 9 partners: industries (4), academic and clinical institutions from 5 countries (engineers, physicists and radiologists) representing cutting-edge expertise in their fields, to develop an innovative non-invasive, point-of-care, low-cost, easy-to-operate, multi-modal imaging system (diffuse optics and ultrasounds/shear wave elastography) for high-specificity diagnosis of breast cancer, the most common female cancer in Europe. Mammographic screening is effective in reducing mortality, however the 10-year cumulative false-positive risk is 50-60%, leading to needless additional invasive procedures (e.g. biopsy). The project addresses the unmet clinical need for higher specificity in breast cancer imaging following screening by fully combining photonics with non-photonics techniques, developing and clinically validating innovative and previously unthinkable photonics concepts and components: time-domain small source-detector distance optical tomography, miniaturized picosecond pulsed laser sources, high-dynamic-range time-gated single-photons detectors to achieve unprecedented sensitivity and depth penetration. For the first time, this allows a comprehensive quantitative characterization of breast tissue including composition (water, lipids, collagen), functional blood parameters, morphologic information and mechanical parameters (stiffness). This innovative multi-parametric characterization will significantly improve the specificity of breast screening, with great impact on the quality of life of millions of European women every year, and huge savings for the healthcare systems. The strong involvement of leading industrial players at all levels in the value chain will push the European innovation process and make a significant contribution to ensuring Europe's industrial leadership in the biophotonics healthcare market, while addressing one of the largest societal challenges in health and well-being.
The purpose of the study is to determine the diagnostic role of ctDNA when used to monitor metastatic breast cancer (MBC) during first-line endocrine therapy.
This study evaluates the safety and effectiveness of the da Vinci SP Surgical System compared to Open NSM in Nipple Sparing Mastectomy procedures.
This is a multi-site, global, open-label study that includes a phase 1b evaluation of elacestrant in combination with abemaciclib in women and men with with or without brain metastases from ER-positive, HER-2 negative breast cancer. Phase 1b is designed to select the recommended phase 2 dose and will be followed by a phase 2 evaluation of elacestrant in combination with abemaciclib in patients with active brain metastases from ER-positive, HER-2 negative breast cancer.
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.
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.
