Filter by:Previous studies have found good efficacy of (investigator's choice of chemotherapy, or endocrine drug) in combination with apatinib mesylate in the treatment of her-2 negative, chest wall metastatic advanced breast cancer, and the present study proposes to further explore the efficacy of apatinib mesylate in her-2 negative, HR-positive advanced breast cancer.
Cyclin-dependent kinase (CDK) 4/6 inhibitors are a class of agents recently introduced in the clinic for the treatment of advanced hormone receptor-positive (HR+) and HER2-negative (HER2-) BC. Palbociclib, ribociclib and abemaciclib have all been approved by the US Food and Drug Administration (FDA) and the European Medicines Agency among other regulatory bodies
CDK4/6 inhibitors have led to an improvement of both progression free survival (PFS) and overall survival (OS) in patients with advanced estrogen positive (ER+)/HER2- breast cancer when applied in the first or second line of treatment. Despite the advantages of CDK4/6 inhibitors, these medications can lead to adverse effects. One of the adverse events observed across all types of CDK4/6 inhibitors is an elevation in creatinine levels. An elevation in plasma creatinine during treatment with abemaciclib is not always indicative of a reduction in renal function; it can also be attributed to the inhibition of active tubular secretion of creatinine. This phenomenon is known as pseudo acute kidney injury (pseudo-AKI). The incidence of pseudo-AKI in patients using CDK4/6 inhibitors is currently unknown. A method to distinguish pseudo-AKI from AKI is measuring the level of an alternative filtration marker in blood, for example cystatin C. Cystatin C is also filtered at the glomerulus but not secreted intro the renal tubulus or reabsorbed into the bloodstream. Also, there is no affection by muscle mass or diet. In this study the investigators will explore the incidence of both AKI and pseudo-AKI in patients who are treated with CDK4/6 inhibitor treatment by assessing both creatinine and cystatin C in plasma.
The goal of this study is to evaluate the impact of the "Traditional Chinese Medicine Therapy Program for Reinforcing Vital Energy" on patients with breast cancer who are currently undergoing conventional Western medical treatments in Taiwan. The main questions it aims to answer are: Can the "Traditional Chinese Medicine Therapy Program" alleviate symptoms experienced by breast cancer patients? Does the program improve the quality of life for breast cancer patients receiving Western medical treatments? How does the program contribute to the management of side effects associated with Western oncological therapies? Participants will: Engage in the "Traditional Chinese Medicine Therapy Program for Reinforcing Vital Energy" provided by the Taiwan Compassionate Cancer Care Association. Receive supportive and educational services, including auxiliary Chinese medicine treatment courses, lifestyle and health education, and psychological counseling. This study seeks to integrate the concept of holistic healthcare, emphasizing coordinated care that encompasses physical, mental, and social aspects, into the treatment of breast cancer.
This study evaluates whether a special type of blood analysis, called liquid biopsy (LBx), correlates with mammography results and/or diagnosis of breast cancer.
The purpose of this research study is to develop and test an intervention designed to improve mood and reduce symptoms of depression.
Conventional nipple and/or skin-sparing mastectomy (NSM/SSM) with or without immediate reconstruction is becoming one of the mainstream surgical treatment for breast cancer and risk reducing mastectomy in recent years. While this technique provides satisfactory oncologic and aesthetic outcomes, its disadvantages include skin flap and/or nipple-areolar complex (NAC) necrosis, NAC malposition/distortion as well as visible scar(s) on the breast. In terms of technical aspects, NSM/SSM has its inherent challenges in view of limited incisions and thereby difficulties in dissection. Since 2015, a number of institutions worldwide had adopted a new technique of NSM/SSM using robotic surgical system. Institutional experiences worldwide demonstrated feasibility and safety of this technique coupled with improved patients' satisfactions. To date, there is no center in Singapore or the region offering Robotic NSM/SSM (R-NSM/R-SSM). The authors believe that robotic mastectomy is a feasible and safe technique that can be utilized in our institution and it provides superior aesthetic outcomes with less morbidity and higher patient satisfaction if compared to conventional NSM/SSM. The aim of this study is to conduct a single-arm prospective pilot study to investigate the safety and feasibility as well as learning curve of R-NSM/R-SSM.
The present study aims to investigate the impact of Tumescent Local Anesthesia (TLA) on pain perception following surgeries typical for breast cancer. Previous research has already confirmed the feasibility of conducting operations in TLA for benign breast conditions. In contrast to general anesthesia, Tumescent Local Anesthesia involves local anesthesia of the surgical site, allowing patients to remain awake during the procedure and eliminating the risks associated with general anesthesia. Additionally, if needed, sedatives or further anesthesia can be administered through the vein. Building upon the successful applications of TLA in benign breast surgeries, this follow-up study at the Department of Women's Health focuses on enhancing surgical techniques, pain management, and postoperative care for breast cancer-related procedures. Simultaneously, our goal is to gather scientific data regarding the application of this technique. This research contributes to the continuous advancement of medical practices in the field of breast surgery.
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.
This study aims to conduct whole genome sequencing in breast cancer patients to elucidate individual genetic characteristics and their correlation with breast cancer subtypes. The primary objective is to establish new treatment guidelines aligned with the paradigm shift in precision medicine. The study will include both prospective and retrospective cohorts totaling 1200 participants. Prospective participants must provide consent and be eligible for tissue collection, while retrospective participants must have histologically confirmed breast cancer and available tissue samples from Samsung Medical Center Biobank. The study period spans 3 years for subject enrollment and 5 years for follow-up observations, with an expected completion date of December 31, 2030.
