Construction of a Benchmark for Breast Ultrasound AI Interpretation and Performance Evaluation of Multimodal AI Models

This single-center, retrospective, observational study aims to construct a standardized benchmark evaluation system for intelligent breast ultrasound image interpretation and to systematically assess the diagnostic performance of current mainstream multimodal artificial intelligence (AI) models. De-identified B-mode breast ultrasound images with confirmed pathological diagnoses will be retrospectively collected from the institutional archive (2018-2025) and supplemented with images from published open-access datasets. Expert radiologists with varying experience levels will independently annotate all images according to the American College of Radiology (ACR) Breast Imaging Reporting and Data System (BI-RADS) v2025 criteria, including glandular tissue composition, lesion characterization (mass vs. non-mass lesion), morphological descriptors, and final BI-RADS classification. Baseline deep learning models (CNN-based ResNet-50 and Transformer-based USFM) will be trained to establish performance baselines and to stratify cases by diagnostic difficulty through cross-architecture consensus. Multiple multimodal large language models (MLLMs), including both general-purpose and medical-domain models, will then be evaluated via standardized API calls using BI-RADS-guided chain-of-thought prompts at temperature 0 for reproducibility. Primary endpoints include BI-RADS classification accuracy and diagnostic AUC for benign-malignant differentiation. Model robustness and safety will be assessed through out-of-distribution rejection testing, temperature-stability experiments, and thinking-mode ablation studies. This study adheres to the FLAIR and TRIPOD-LLM reporting guidelines.

18F-FDG Versus 68Ga-FAPI-46 as PET Tracer in ER-positive Breast Cancer.

The extent of breast cancer is an important prognostic factor in patients diagnosed with this disease. Therefore, adequate staging at diagnosis is a requisite for optimal treatment. In all patients diagnosed with locally advanced breast cancer (LABC), distant staging using 18F-FDG PET/CT is recommended. However, the degree of metabolic uptake in the primary breast tumor is significantly lower in the ER+ subtype compared to HER2+ and triple negative breast cancer (TNBC). As a consequence, a suboptimal 18F-FDG uptake in ER+ breast cancer patients can potentially lead to missed distant metastases. Fibroblast-activating protein inhibitor (FAPI) is a recently developed radiotracer that binds to FAP, a stromal antigen overexpressed in more than 90% of epithelial-derived tumors and their metastases. Previous studies all show 68Ga-FAPI PET/CT to have a higher detection rate compared to 18F-FDG PET/CT. However, all previous studies were performed without considering breast cancer subtype. If the metabolic uptake by 68Ga-FAPI-46 is higher in ER+ breast cancer patients, more lesions will be detected, resulting in a more appropriate treatment for these patients. Therefore, in this pilot study, the investigators aim to compare the diagnostic performance of 18F-FDG with 68Ga-FAPI-46 as PET-tracer in ER+ breast cancer patients.

A Study of Treatment-Related Toxicities and Quality of Life After Local Therapy in Chinese Breast Cancer Patients

This study, called PERSEVERE, examines how local treatment for early breast cancer affects people's health and daily lives over time. People who join the study will have early-stage breast cancer and receive treatment such as surgery and other therapies that are used before or after surgery. The study does not include people with late-stage (metastatic) breast cancer. Researchers want to learn about short- and long-term side effects that can happen during or after treatment. These may include tiredness, trouble sleeping, emotional distress, pain, or changes in heart or lung function. The study also looks at how these effects impact participants' quality of life. Participants will be asked to complete surveys about how they feel. They will also have health checks, such as heart tests, lung function tests, and blood samples. Tissue samples from surgery will also be collected. The goal is to understand better how different people respond to breast cancer treatment and find ways to support long-term recovery.

Anastrozole, Palbociclib, Trastuzumab and Pertuzumab in HR-positive, HER2-positive Metastatic Breast

This is a multicenter, phase I/II trial of anastrozole, palbociclib, trastuzumab, and pertuzumab is proposed as first-line therapy in metastatic hormone receptor-positive, HER2-positive breast cancer patients. In this phase I/II clinical trial, the researchers aim to establish the safety and efficacy of dual HER2 therapy in combination with palbociclib and anastrozole, which represents a novel and all biologic approach to the treatment of HR+, HER2+ metastatic breast cancer. Additionally, the researchers aim to examine potential biomarkers of response to palbociclib including cyclin D1, cyclin E1 and cyclin E2 expression levels, CDK 2, 4, and 6 levels, phosphorylated retinoblastoma expression and p16 levels. The researchers intend to use RNA sequencing to assess for other predictors of response in an unbiased manner to see if this correlates with inhibition of Ki-67 and phosphorylated retinoblastoma expression as well as evaluate for potential mechanisms of resistance.

Studying the Effect of Denosumab on Preventing Breast Cancer in Women With a BRCA1 Germline Mutation

This phase III trial compares denosumab to placebo for the prevention of breast cancer in women with a BRCA1 germline mutation. A germline mutation is an inherited gene change which, in the BRCA1 gene, is associated with an increased risk of breast and other cancers. Denosumab is a monoclonal antibody that is used to treat bone loss in order to reduce the risk of bone fractures in healthy people, and to reduce new bone growths in cancer patients whose cancer has spread to their bones. Research has shown that denosumab may also reduce the risk of developing breast cancer in women carrying a BRCA1 germline mutation.

Sacubitril/Valsartan in PriMAry preventIoN of the Cardiotoxicity of Systematic breaST canceR trEAtMent (MAINSTREAM)

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 transthoracic echocardiography (TTE). 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 (optionally), electrocardiography including 24-h Holter monitoring, blood tests, functional capacity tests and quality of life assessment.

REGENERA Implant in Localized Non-malignant Breast Lesions Treated by Excision or Lumpectomy - Long-term Follow-up

In a previous first-in-human (FIH) study we assessed safety and performance of REGENERA in 15 patients treated for breast deformities following excision or lumpectomy. The technique was minimally invasive, easily repeated and associated with minimal surgical morbidity. It is important to assess whether the positive safety and performance results obtained during the initial 6 months post- surgery are maintained in the long-term, for up to 5 years after surgery. In this long-term follow-up study we will assess long-term safety and performance of REGENERA implant after excision or lumpectomy of breast tissue in patients with non-malignant lesions.

A Randomized Controlled Study of Conservative Treatment of Granulomatous Lobular Mastitis Combined With Psychiatric Disorders

Granulomatous lobular mastitis (GLM) is a relatively rare chronic inflammatory disease of the breast in clinical practice. A small number of patients develop hyperprolactinemia during psychiatric drug treatment, and most of these patients are nulliparous. At present, there is no unified treatment mode at home and abroad, and surgery is generally the main treatment. GLM is a sterile inflammation, and glucocorticoids and methotrexate can effectively relieve clinical symptoms and even reach the standard of cure. In order to reduce the recurrence rate and protect the breast appearance as much as possible, we propose a conservative therapy. The purpose of this study was to compare this conservative therapy of granulomatous lobular mastitis with existing surgical treatment, and to compare the overall benefits of the two for patients with GLM. We aim to protect the breast appearance on the premise of low recurrence, improve the quality of life of GLM patients with psychiatric disorders .
