Breast Cancer Invasive

To determine the effect of low dose azacitidine therapy on tumor infiltrating lymphocytes (TILs) in primary tumors from patients with high-risk early stage breast cancer, paired t-tests will be first used to compare TIL count in pre- and post-treatment specimens.

This research study is a prospective, single arm, pilot study, designed to evaluate the correlation between the immune and clinical responses of subjects with untreated Stage II-III triple negative breast cancer (TNBC) undergoing standard of care neoadjuvant chemo- immunotherapy.

Liquid biopsy is a noninvasive method for detecting and quantifying circulating tumor cells (CTCs). Thanks to ScreenCell technology, this study aims to evaluate the evolution of the number of CTCs during breast cancer follow-up. The identification and characterization of CTCs would make it possible to obtain information on the stage and molecular characteristics of cancer during follow-up

AUDIBLE is a multi-site, clinical study conducted in the United States aimed at gathering data on 3D Automated Breast Ultrasound imaging using the iSono Health ATUSA system. The study focuses on female participants who have previously been identified with suspicious findings (classified as BIRADs 4 or 5) through standard-of-care diagnostic imaging methods (e.g., hand-held ultrasound, mammograms) and who have been referred for a biopsy. The goal is to create a comprehensive registry that includes multi-modality breast images alongside and biopsy results. The study will enroll up to 800 eligible female patients. In addition to imaging data, the study will collect information from the patient's medical records and biopsy outcomes. The study aims to validate ATUSA's image quality, reproducibility, and correlation with histopathology and radiologist-assigned BI-RADS categories. Additionally, a subset of participants receiving neoadjuvant therapy will be followed longitudinally to evaluate ATUSA's potential for monitoring treatment response and volumetric changes in tumor burden. This study supports the advancement of a patient-friendly, radiation-free, operator-independent ultrasound platform for real-time breast imaging.

This is a single institution phase II randomized study evaluating the potential benefits of a supplement, tart cherry juice at high- versus low-doses, to prevent taxane induced peripheral neuropathy in breast and ovarian cancer patients undergoing paclitaxel chemotherapy. Eligible participants enrolled onto the study will be block randomized in a 1:1 allocation to either the tart cherry juice high-dose group (Arm 1) or the tart cherry juice low-dose group (Arm 2).

The study aims to develop educational media interventions to prepare Latinx Spanish-speaking radiation oncology patients for a course of breast or prostate cancer radiation therapy and to foster receptivity and informed decision-making around cancer clinical trial participation.

This study will evaluate the immune-priming effects of stereotactic body radiation therapy (SBRT) regimen coupled with two injections of pembrolizumab in high-risk primary breast carcinoma prior to neoadjuvant chemotherapy. Preliminary results from the investigators' local TRIO Trial suggest that SBRT prior to neoadjuvant chemotherapy (NAC) may result in improved response rates due to the combined effect of radiation therapy (RT) and chemotherapy. The investigators aim to augment this effect with the addition of pembrolizumab, a monoclonal antibody that binds to and blocks programmed cell death protein 1 (PD-1).

The clinical performance study is collecting data from the use of a CE mark product used within the scope of its intended purpose to intraoperatively visualize tissue specimen. The subjects are not submitted to invasive and burdensome procedures compared to the standard of care surgical practices and regular use of the CE mark product.

This is a prospective, randomised, controlled, multicentre study to compare the efficacy and safety between continuous or intermittent extension of adjuvant pyrotinib in invasive human epidermal growth factor receptor 2 (HER2)-positive breast cancer.

Background: Breast cancer became the most prevalent cancer globally in 2020, and post-surgery radiotherapy is crucial for most patients. Traditional radiotherapy is complex and time-consuming, affecting patient experience. To streamline this, an AI-assisted All-in-one (AIO) radiotherapy approach has been developed, integrating steps like target delineation and planning to reduce wait times and enhance accuracy. Preliminary results are promising, with significant time savings and high pass rates in initial assessments. Further exploration is needed to confirm the accuracy, effectiveness, and safety of AIO radiotherapy. Primary objective: To conduct a prospective phase II clinical trial to determine the feasibility (including efficacy and safety) of AIO radiotherapy, and to provide a basis for establishing standard operating procedures. Secondary objectives: To assess the impact of AIO radiotherapy on overall survival, local regional recurrence, and distant metastasis rates. To investigate the incidence and contributing factors of cardiac damage after AIO radiotherapy.

The goal of this clinical study is to learn if serplulimab is effective in early HR+/HER2- breast cancer. This trial serves a prospective parallel control cohort for HELEN-018 (NCT). The main questions it aims to answer are: Does serplulimab combined with neoadjuvant chemotherapy improve the pCR rate of early HR+/HER2- breast cancer? What medical problems do participants have when receiving serplulimab? Researchers will compare the effect of serplulimab combined with chemotherapy to the effect of chemotherapy reported in literature. Participants will: Receive serplulimab plus chemotherapy every 3 weeks for 6 cycles; All patients will receive surgery, and the primary end point is a pathological complete response at the time of definitive surgery; After definitive surgery, the participants will receive adjuvant serplulimab every 3 weeks for up to 6 months from the begining of the treatment.

Breast cancer-related lymphedema (BCRL) is one of the most common chronic complications following breast cancer treatment. This study enrolls breast cancer patients who are required to undergo axillary lymph node dissection and postoperative adjuvant radiotherapy. Based on patients' preferences, they will be assigned to receive either immediate distal lymphaticovenous anastomosis (ID-LVA) following axillary lymph node dissection (experimental group) or not (control group). The study aims to evaluate the safety and efficacy of ID-LVA in preventing breast cancer-related upper limb lymphedema.

In this project, we will develop a unique OCT-Raman system based on a selective sampling approach optimised for high-resolution analysis of whole lumpectomy specimens. The aim of using OCT is not to detect the cancer but to identify the adipose tissue, such that the large adipose tissue regions are excluded from any further measurements by Raman spectroscopy. While OCT has a limited ability to distinguish between tumour and surrounding normal stroma, adipose tissue has a distinctive appearance in the OCT images due to low backscattering within adipose cells (filled with lipids and small/flattened nuclei) compared to the highly scattering benign dense tissue (stroma, ducts and lobules) and malignant tissue. Such specific patterns allow identification of normal adipose tissue from breast tissue (classification models based on reflectivity profiles) with 94% sensitivity and 93% specificity. This will reduce the task of Raman measurements, which can be focused on the smaller remaining regions to discriminate between the benign and malignant tissue. This flexible and adaptable scanning strategy will achieve a much-improved diagnosis accuracy and speed to cover all surgical margins within practical timescales.

This pilot study will test the feasibility of using nanopore sequencing for breast cancer diagnosis in Tanzania. It aims to show that nanopore sequencing is non-inferior to the current standard of care, with the potential for faster and more cost-efficient results. By enhancing the speed and accuracy of diagnosis, this approach could improve treatment planning and outcomes for patients in resource-limited settings.

Global cancer statistics by world region for the year 2022 estimated breast cancer the 2nd cause of new cancer cases (11.6%). (1) Approximately 80% of all breast cancers (BCs) are currently categorized as human epidermal growth factor receptor 2 (HER2)-negative. (2) Most breast cancer cases can be cured by multimodality treatment, although cure rates vary by clinical stage, subtype and the clinical behavior of cancer which affected by the composition of pro- and anti-tumor immune mediators within the tumor microenvironment. (3, 4) Immune gene signatures in breast tumors -that comprise genes with specialized roles in immune biology- Significantly, have been shown to correlate with patient survival outcomes. (5-8)chemotherapy responsiveness. (7, 9), and more recently, response to immunotherapies.(10-12)One such candidate, the gene encoding Triggering Receptor Expressed on Myeloid Cells (TREM)-1, which emerged as a robust therapy predictive and prognostic marker. TREM1 encodes a type I trans-membrane receptor of the Ig superfamily expressed by effectors of innate immunity including neutrophils, monocytes and macrophages. The TREM-1 receptor is known to augment inflammatory signaling in response to infectious pathogens by promoting release of cytokines that modulate the activation, recruitment and survival of myeloid and lymphoid cells. (13) In this study we hope to gain a better understanding of TREM-1 clinical and molecular relevance in HER2 negative BC either triple negative or hormonal positive which represent significant subset that lack target therapeutic options, evaluating its effect as predictive and prognostic marker and so the potential implications for patient management.

The purpose of this study is to learn whether clinical response (the amount a tumor shrinks based on imaging or tumor measurements obtained by physical exam) predicts pathologic response (the amount of tumor remaining when surgery is performed) in participants with breast cancer who are receiving chemotherapy prior to surgery.

The primary aim is to evaluate the efficacy of neoadjuvant SBRT combined with PD-1 monoclonal antibody and chemotherapy in patients with triple-negative breast cancer, with the endpoint being the pCR rate-defined as the proportion of patients with no residual invasive cancer in the breast and no axillary lymph node metastasis after treatment. This is a single-arm study. Eligible participants will receive : neoadjuvant treatment consisting of SBRT followed by Envafolimab (PD-1 inhibitor), chemotherapy and immunotherapy (Envafolimab). Surgery will be performed after the last chemotherapy cycle. Pathological evaluation will assess the treatment response. Patients will receive adjuvant immunotherapy (Envafolimab) up to 1 year post-surgery.

Patients with oligoprogression of metastatic breast cancer during palliative treatment that is amenable to local therapy will be included. The local ablative therapy (LAT) may consist of stereotactic ablative radiotherapy (SABR), also known as stereotactic body radiation therapy, surgery or radiofrequency ablation (RFA).

This study is a prospective, non-interventional, open-label study to evaluate the glucose metabolism and the expression of the imaging agent 68 Gallium-Fibroblast Activation Protein Inhibitor-46 (68Ga-FAPi-46) with PET imaging, in woman affected by Breast Cancer (BC) and referred to diagnostic imaging work-up prior to primary therapy.

To explore the efficacy of 68Ga-GZMB PET/CT in assessing the response to neoadjuvant therapy for breast cancer, and to investigate the optimal SUVmax threshold of 68Ga-GZMB PET/CT for predicting pathological complete response (pCR), aiming to provide a new and effective means for accurately and non-invasively evaluating the efficacy of neoadjuvant therapy.

With the title of "Long-Term Outcomes of endoscopic-assisted vs conventional breast-conserving surgery in breast cancer patients after neoadjuvant therapy: a randomized, multicenter, open label, non-inferiority trial", this study targets breast cancer patients after neoadjuvant therapy. A total of 1380 eligible patients, after screening with inclusion and exclusion criteria, will be randomly assigned to Endoscopic-assisted breast conserving surgery(E-BCS) or conventional breast conserving surgery (C-BCS) group at a 1:1 ratio using stratified block randomization method, stratified by centers and molecular subtype. The co-primary endpoints are 5-year disease-free survival (5y-DFS) and Breast-Q score at 6 months after surgery. The secondary endpoints are cosmetic outcomes including surgeons' satisfaction with breast and patients' satisfaction with scar, survival outcomes including 5-year overall survival (5y-OS) and 5-year local-recurrence rate (5y-LRR), surgical outcomes including operative time, intraoperative blood loss, incision length and postoperative complications rate. This study aims to confirm the long-term safety and aesthetic outcome of endoscopic-assisted surgery in breast cancer patients after neoadjuvant treatment by comparing it with conventional open breast conserving surgery, and provide clinical evidence for the popularized application of endoscopic breast surgery.

The study aspires to provide outcomes on surgery, quality of life and time-to-event outcomes following the development and validation of a standardised surgical assessment tool in a shared decision-making framework for patients with pre-invasive or invasive breast cancer with breast conservation.

A prospective, multicenter, single-arm non-inferiority trial to demonstrate that breast cancer patients who are predicted to have a pathologic complete response on MRI and vacuum-assisted biopsy after neoadjuvant systemic therapy, and are omitted breast surgery have a non-inferior 5-year disease-free survival compared to those who had received breast surgery.

We have previously demonstrated that high-frequency ultrasound and spectroscopy, and recently conventional-frequency ultrasound and spectroscopy may be used to detect cell death in vitro, in situ and in vivo. The method can detect different forms of cell death and has been demonstrated to be sensitive to apoptotic, necrotic and mitotic cell death. The objectives of this study are to evaluate the use of ultrasound imaging and spectroscopy as a predictive marker of advanced tumour response to combined chemotherapy and radiotherapy. Since neoadjuvant treatments may also act on tumour vasculature to "normalize" it we will also evaluate blood-vessel imaging by standard Doppler-imaging and with standard higher-resolution imaging using clinically approved microbubble contrast agents. The main goal, as described above, is to select the best ultrasound spectroscopy parameter to use as an early predictor of pathological complete response.
