Filter by:Perioperative SARS-CoV-2 infection significantly increases the risk of postoperative complications and mortality, while also exerting long-lasting impacts on multiple organs and systems. Due to the curtailment or cessation of non-emergency surgeries during the initial phase of the pandemic, there is a lack of evidence regarding the optimal timing and medium- to long-term postoperative outcomes of surgical intervention in breast cancer patients with prior SARS-CoV-2 infection, particularly after vaccination. We aim to investigate whether prior SARS-CoV-2 infection increases the risk of postoperative adverse outcomes in breast cancer patients and determine the optimal timing for surgical intervention during the pandemic, as well as to longitudinally assess the evolution of postoperative adverse outcomes within one year after COVID-19 and identify associated risk factors.
The study's objective is to compare the diagnostic accuracy of the contrast-enhanced mammography (CEM) , considering as reference the classification obtained with Vacuum Assisted Breast Biopsy (VABB).
This is a non-interventional observational study conducted in Germany to evaluate the real-world effectiveness, tolerability, safety, and quality of life in patients with locally advanced/metastatic HR+/HER2- breast cancer treated with one of the following 1st line treatments: Ribociclib + AI/FUL, or endocrine monotherapy, or chemotherapy
The goal of this clinical trial is to evaluate the effectiveness of mastectomy flap fixation in breast cancer patients. The main questions it aims to answer are: - To compare seroma formation after mastectomy flap fixation with conventional surgery in breast cancer patients Participants will be randomly divided into 2 groups, 1. Mastectomy flap fixation 2. Conventional surgery with non flap fixation. Researchers will record the amount and color of drainage fluid, patient and tumor characteristics, and operative related factor after surgery. Researchers will compare with conventional surgery to see if seroma formation, and wound infection.
There is no granular retrospective data on breast cancer in transgender and gender-diverse (TGD) persons from a contemporary and diverse American cohort. The purpose of this investigation is to aggregate data from multiple institutions to describe the risk, diagnosis, management, and outcomes of TGD persons with breast cancer in effort to identify opportunities for future intervention studies to eliminate breast cancer disparities for this population.
A national, multicenter, retrospective, observational study (Real-World Evidence-RWE) aimed to assess the efficacy of Trastuzumab-deruxtecan (T-DXd) in patients with triple-negative (RE<10%) metastatic HER2-Low breast cancer.
The main goal of this study is to assess the impact of supervised intense physical activity (IPA) on outcomes of neoadjuvant chemotherapy in young women with breast cancer (YWBC). In this project standard neoadjuvant chemotherapy will be used concordant with summary of product characteristics (SPC). However during treatment (including days of chemotherapy application) an additional modifier of therapy will be carried out in the form of intense physical activity. This strategy is not recognized in SPC. This project aims to improve the results of breast cancer treatment in young women. According to available data, nowadays this subset of breast cancer patients has worse therapy results in comparison to older women. This is partially because of the different tumor characteristics; young women are more likely to present with human epithelial growth factor receptor 2 (HER2) receptor overexpression or with triple negative breast cancer. In the treatment of YWBC, preoperative chemotherapy is most often the first step. This enables the opportunity to assess the effectiveness of additional interventions in a mode it was never tested before. It is believed that physical activity improves the results of breast cancer treatment, however there are only few reports describing its benefit and role in terms of preoperative chemotherapy. In the current project, the investigators planned to introduce supervised increased physical activity concurrently with neoadjuvant treatment in YWBC at early stage of disease. The main goal of the study is to assess the effect of physical activity on preoperative chemotherapy outcomes. The change of tumor size after neoadjuvant chemotherapy, as well as the impact on Quality of Life (QoL) and Patients' Reported Outcome (PRO) in described above treatment modality. Secondary endpoints are the following: the pathologic Complete Response (pCR), disease free survival after 3 years (3-yr DFS), overall survival (OS), cardiotoxicity of treatment, the effect of physical activity on tumor microenvironment and Ki67 as well as the impact of increased physical activity on further patients' lifestyle changes.
Foreign data show that: 1807 tumor patients were followed up for 7 years, 33% of them died of heart disease and 51% of them died of the tumor itself. In China, the number of cancer patients undergoing chemotherapy is increasing rapidly every year. How to protect the heart of chemotherapy patients from the damage of chemotherapy drugs (especially anthracyclines) is a problem that clinicians must face.In order to further confirm the clinical efficacy and value of saffron total glycosides tablets in the protection of central function of breast cancer neoadjuvant patients with anthracycline based chemotherapy scheme, the project plans to follow up and observe the research of saffron total glycosides on the protection of cardiac function of breast cancer neoadjuvant patients with chemotherapy based on cardiac color ultrasound combined with myocardial zymography, and randomly group to confirm the effectiveness of saffron total glycosides tablets on cardiac protection, Based on the clinical observation and research on the effect of traditional Chinese medicine on the cardiotoxicity of anthracycline drugs, confirm its efficacy, explore the mechanism of cardiac protection, and explore the drug use method of synergism and toxicity reduction of anthracycline drugs in combination with this active ingredient.
This clinical trial is a randomized controlled trial that aims to assess the usefulness of adding pentoxifylline to the neoadjuvant chemotherapy treatment protocol of doxorubicin/cyclophosphamide for breast cancer patients to decrease the incidence of developing oral mucositis, downgrade the mucositis symptoms, alleviate the associated pain using the visual analogue scale, and enhance the quality of patient life using the EQ-5D-3L questionnaire. The participant will administer Pentoxifylline oral tablets three times per day along with the treatment protocol, starting from the first doxorubicin/cyclophosphamide cycle till the end of the fourth cycle. The researchers will compare the mucositis incidence and grade in the presence or absence of oral pentoxifylline.
This prospective randomized study investigated the reproducibility of breast shape, radiation dose irradiated to the lungs, heart, dose distribution, patient satisfaction, and treatment toxicity when wearing and not wearing a bra during radiotherapy for patients with breast cancer.
