I this qualitative study, Investigators will conduct semi-structured interviews with clinicians that are involved in the care of patients with breast cancer to evaluate the acceptability, appropriateness, and feasibility/usability of a metastatic breast cancer-specific prognostic tool. These interviews will be conducted by the UNC CHAI Core and will continue until thematic saturation (estimated 10 participants). The investigators will code the qualitative data using emerging themes, guided by a well-established implementation science theory, the Consolidated Framework for Implementation Research (CFIR). The information gained from these studies will inform an implementation approach to increase the usability and acceptability of a novel prognostic tool to assist oncologists in the prognosis of patients with metastatic breast cancer.
The primary objective of the investigators is to develop an integrated algorithm for surgical treatment of chronic lymphedema after breast cancer surgery. This will be achieved by retrospectively analysing a subgroup of patients who had breast cancer-related surgery prior to lymphedema.
The standard or usual treatment for this disease is to undergo chemotherapy to slow the spread of disease and relieve some symptoms of cancer. One of the standard types of chemotherapy is a drug called paclitaxel (Taxol) given in a low dose every week for three out of four weeks. CFI-402257 is a new type of drug for breast cancer. Laboratory tests show that it may help slow the growth of breast cancer. This drug has been shown to shrink tumours in animals. CFI-402257 has been studied in a few people and appears well tolerated with little side effects. CFI-402257 seems promising but it is not clear if it can offer better results when given with paclitaxel compared to paclitaxel alone.
This multicenter, randomized, double-blind study aims to assess the safety and efficacy of AK112 in combination with Nab-Paclitaxel, compared to a placebo plus Nab-Paclitaxel, as a first-line treatment for inoperable locally advanced or metastatic triple-negative breast cancer (TNBC).

Although treatments for breast cancer have improved, 20-30% of patients with early disease develop metastases (cancer that spreads to other parts of the body). Among the different types of breast cancer, hormone-sensitive cancers that do not overexpress the HER2 protein (HR+/HER2-) are the most common. For patients with this type of cancer, an endocrine treatment such as aromatase inhibitors, tamoxifen or fulvestrant, is often used and may be combined with drugs called CDK4/6 inhibitors, which help improve survival rate. However, when the cancer becomes resistant to these treatments, treatment strategies are more limited A new drug, prifetrastat (PF-07248144), which targets KAT6 proteins, which play a role in the growth of cancer cells, has shown promising results. Indeed, associated with fulvestrant, it allowed to fight against cancer in some patients who had already received many treatments. The UNLOCK-EPIBREAST study aims to investigate whether the combination of prifetrastat plus fulvestrant could offer a new therapeutic option for people with HR+/HER2- metastatic breast cancer who have already received endocrine therapy plus CDK4/6 inhibitors.
The purpose of this non-interventional, observational study is to evaluate the clinical utility of circulating tumor DNA (ctDNA) utility-specifically how quickly tumor DNA disappears from the bloodstream (ctDNA clearance)-to help monitor and predict treatment responses in patients with breast cancer. The study focuses on patients diagnosed with Stage II to III HER2-positive or Triple-Negative Breast Cancer (TNBC) who are scheduled to receive standard neoadjuvant therapy (systemic treatment administered before surgery). Because these breast cancer subtypes involve different standard treatment regimens, the study prospectively stratifies patients into three distinct treatment cohorts (Cohorts A, B, and C) to match routine clinical practice and align blood sampling with meaningful clinical milestones.
The high cost of diagnostic equipment, limited expertise, and inadequate infrastructure are major barriers to early breast cancer diagnosis in low- and middle-income countries. Point-of-care ultrasound (POCUS) offers a relatively low-cost, portable solution that, when combined with artificial intelligence (AI)-driven image analysis, has the potential to significantly expand access to breast assessment in these settings. The purpose of this study is to evaluate the performance of POCUS for women with focal breast symptoms and to assess the performance of AI to analyze POCUS images. The study will be divided in two parts: a prospective interventional study and a retrospective multicase multireader study.
Hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-) breast cancer constitutes approximately 70% of all breast cancer cases. Although early-stage patients generally have favorable outcomes following standard surgery and adjuvant endocrine therapy, long-term follow-up data reveal a distinct "bimodal" or "long-tail" recurrence pattern, with risks persisting for decades. Recent landmark trials (e.g., NATALEE, MonarchE) have established that combining CDK4/6 inhibitors with endocrine therapy significantly improves invasive disease-free survival (iDFS) in high-risk populations. However, the stringent enrollment criteria of these randomized controlled trials may not fully capture the heterogeneity of real-world patients. Reliance on binary cut-off values (e.g., nodal status alone) risks misclassifying biologically high-risk individuals with low anatomical burden, leading to either undertreatment or overtreatment. There is an urgent clinical need for a multidimensional, individualized risk assessment tool to guide escalated therapy decisions.
To de-escalate radiation therapy in women with breast cancer.
The purpose of this study is to characterize the breadth of molecular features present in participants receiving care within a large, integrated, community-based healthcare system. Through comprehensive genomic profiling, investigators aim to identify the underlying genomic drivers of premalignant and malignant conditions across a range of disease stages and cancer types. Comprehensive molecular profiling will include somatic tumor testing (tissue and/or blood) using next-generation sequencing. Selected subsets of samples may undergo whole exome and/or whole transcriptome sequencing for research purposes. Pharmacogenomic testing will also be performed to better understand individual variability in medication response and to identify opportunities for optimizing treatment. In addition, participants may optionally provide microbiome samples. To maximize the value of the genomic data, participants who consent to this protocol will have their electronic health records-both retrospective and prospective-abstracted, curated, annotated, and linked to the genomic data generated through study testing. Given the long-term value of these data, participants may also voluntarily consent to the storage of their biological samples in a biobank and to the use of their de-identified information for future research. Data collected from this participant population will support efforts to advance the understanding of cancer biology, as well as the discovery and validation of biomarkers associated with clinical outcomes. Findings may also be shared through collaborative research initiatives to further promote advancements in cancer research.
The purpose of this study is to evaluate the efficacy and safety of Letrozole SIE (injectable) compared to Femara® (oral tablet), both given together with ribociclib, for the first-line treatment of postmenopausal women with HR-positive, HER2-negative, inoperable locally advanced or metastatic breast cancer.
The use of wound drains after mastectomy is common practice in Belgium. However, placement of suction drainage has several disadvantages. Skin bacteria can enter via the drain and cause infection, or the drain itself can cause discomfort and a need for daily nursing. After drain removal, seroma is the most common complication following breast cancer surgery. Seromas are collections of serous fluid that frequently develop under the skin or in the axillary space formed after mastectomy and/or axillary lymph node dissection, resulting from surgical trauma to blood/lymphatic vessels and post-traumatic inflammation. Seroma formation can cause discomfort and limitations in shoulder function. Moreover, it is associated with surgical site infections, often requires treatment and increases healthcare consumption. Wound healing problems might be a cause of postponement of adjuvant therapy. The quilting suture technique, in which the skin is sutured to the pectoralis muscle and drain placement is not needed, may lead to a significant reduction of seroma with a decrease in the number of aspirations and surgical site infections. In this national multicentric study, we will compare mastectomy with placement of suction drains, a standard technique used in the vast majority of Belgian hospitals, with the new quilting suture technique without placement of suction drains. We will focus on 3 distinct primary outcomes: * Pain of the mastectomy area 6 months after surgery * Upper limb function 6 months after surgery * Cosmetic outcome scored by the patient 6 months after surgery. The goal of this study is to demonstrate the absence of long-term negative effects of the quilting suture technique on shoulder function, cosmetic outcome, and pain management.
Breast cancer patients who undergo neoadjuvant systemic therapy and have residual breast cancer identified at the time of surgery exhibit a high (\>50%) risk of future life-threatening recurrences and death.
