Filter by:A prospective and retrospective cohort study of patients with a documented pathogenic or likely pathogenic variants of TP53 were identified using blood DNA colection and breast cancer diagnosis by histological confirmation, between 1999 and 2022. All patients were followed by the Hereditary Group of a single cancer center (Instituto do Cancer do Estado de Sao Paulo). Patients were included if they had a histopathological diagnosis of localized invasive carcinoma or in situ carcinoma of the breast and with localized disease. Patients met Revised Chompret criteria, Li Fraumeni like syndrome,family member of carrier TP53 or hereditary breast and ovarian syndrome for germline test.
This study, which is designed according to the experimental model with randomized pre-test and post-test control group, will be carried out with Syrian women who apply to Empowered Migrant Health Center in İstanbul province, Sultanbeyli district, where Syria citizens are immigranted. The population of the study consisted of all Syrian women aged 40-69 under temporary protection who came to the Empowered Migrant Health Center at the time of the research. The working group will be composed of 80 Syrian women who meet the selection criteria. According to the sources, the frequency of breast cancer screening in Turkey is taken as 15%; For the study at 95% confidence level, d=0,6 was taken and n=136 sample size was taken. Considering that there may be those who left during the research period, 14 women will be taken as substitutes and the sample will be completed to a total of 150 in order to increase the power of representing the universe. A personal questionnaire prepared by the researcher in line with the literature, Health Belief Model Scale, Mammography Self-Efficacy Scale, Champion Breast Cancer Fear Scale, Breast Self Examination Checklist Form, will be administered to Syrian women under temporary protection who applied to the empowered migrant health center and agreed to participate in the study.According to the sample pool formed by the women included in the study, the participants were assigned to 2 groups as experiment and control with the "Research Randomizer" program. Each group will be determined as 75 people. A 4-week training program will be applied to the experimental group. The women in the experimental group will be given a self-breast examination control calendar after their first training. Afterwards, motivational interviews will be held once a month for the second and third months. A "Nurse-managed screening consultancy telephone support line" will be established for Syrian women within the scope of the Nurse Navigation Program. Reminder phone calls will be made 4 times a week. Personal questionnaire, Health Belief Model Scale, Mammography Self-Efficacy Scale, Champion Breast Cancer Fear Scale, Breast Self Examination Checklist Form, Post-Training Screening Behavior Follow-up Form will be administered to the experimental and control groups as a post-test.
Introduction: Pain stands out among the sequelae that affect the quality of life of breast cancer survivors. Pain neuroscience education and graded exposure to movement are therapeutic approaches that have been shown to be effective in the management of chronic pain in other populations. However, there are no previous studies that combine them in this population. Objective: To evaluate the effectiveness of an online physiotherapy focused-person program which combines pain neuroscience education and graded exposure to movement, to improve the quality of life of breast cancer survivors. Methodology: The design of the study is a randomised controlled clinical trial and the sample will be 40 breast cancer survivors with pain in the last 6 months. A random method will be used to assign participants into two groups (experimental and control). The evaluator and statistician will be blinded to participant allocation while the experimental group will receive the therapeutic program which combines pain neuroscience education and graded exposure to movement-based intervention throughout therapeutic yoga; the control will be a passive group. There will be four points of assessment: the main outcome assessed will be quality of life measured by the Functional Assessment of Cancer Therapy - Breast (FACT-B+4) and the secondary outcomes are variables related to pain experience (catastrophising, self-efficacy, kinesiophobia and fear-avoidance behaviours). All will be assessed using validated methods. SPSS program will be used for the data analysis. A mixed-model analyses of variance ANOVA (2x4) will be used to study the effects of the treatment on the dependent variables. An intention-to-treat analysis will be performed. All statistical tests will be performed considering a confidence interval of 95%. Trial record: NCT04965909.
This study aims to evaluate the efficacy and safety of U3-1402 in participants with advanced breast cancer (ABC). Participants have to be hormone-receptor positive (HR+) and have to be resistant to endocrine therapy and cyclin-dependent kinases 4 and 6 (CDK4/6) inhibitors. Participants may have received multiple lines of endocrine therapy with or without targeted therapies and must have received only one line of chemotherapy for ABC. Moreover, the immune effects, the predictors of resistance and response to treatment, the effect of the chemotherapy on deoxyribonucleic acid (DNA) replication will be assessed and will help identify the subgroups that will mostly benefit from the treatment. The pharmacokinetics of the product and the anti-drug antibody (ADA) will be also evaluated. A total of 100 participants are planned to be treated in the study. Participants will receive, every three weeks, a dose of U3-1402 equivalent to 5.6 mg/kg of body weight until progression or until unacceptable toxicity. Tumor evaluation will be performed every six weeks by the mean of a computed tomography for the thorax, abdomen and pelvis (TAP CT-scan) or a magnetic resonance imaging (MRI). Brain and/or bone CT scans will be also performed throughout the study for participants with brain and/or bone metastasis. The safety of the product will be assessed at each cycle, through complete clinical exams, biological tests, electrocardiograms (ECGs), cardiac echographies (ECHOs) and through the collection of ongoing toxicities or adverse events.
There are several approved and guideline-recommended treatments for metastatic, estrogen receptor-positive breast cancer that has progressed on an aromatase inhibitor and a CDK4/6 inhibitor. Right now, doctors do not have a good way of choosing between these treatments. Scientists we work with have come up with ways to use the biology of the tumor to try to predict which treatment is best. This study is being done to test if those predictions are right and to learn more about these tumors to design better treatments in the future.
The purpose of this research is to look at the safety and effectiveness of a HER2-targeted therapy neratinib when given with capecitabine, a chemotherapy, for breast cancer patients with brain metastases whose tumors were HER2-negative by standard tests but showed abnormal HER2 activity based on the CELsignia results.
This non-Interventional study will describe and analyze the clinical use of Inetetamab in clinical practice in the treatment of HER2 positive advanced breast cancer in the real world.
Trastuzumab resistance, which is a common therapeutic challenge in HER2 positive metastatic breast cancer, is not fully understood. Pyrotinib is an oral tyrosine kinase inhibitor targeting EGFR, HER-2 and HER-4 receptors. More general inhibition of ErbB family with pyrotinib could provide additional benefit. Inetetamab could bind to HER2 extracellular domain (ECD) with high affinity and inhibit proliferation of multiple HER2-overexpressing cancer cell lines as a single agent or in combination with trastuzumab. This study is designed to evaluate the efficacy and safety of pyrotinib and vinorelbine tartrate capsulesin with or without Inetetamab for first line treatment in patients with HER2 positive metastatic breast cancer who had early failure on or after trastuzumab treatment.
The purpose of this study is to continue to develop a liquid biopsy (minimally invasive blood test) that can be used to confirm if breast cancer has spread throughout the body and if this liquid biopsy test can provide comparable information to a highly invasive tissue biopsy. The knowledge gained in this study could be used in future studies to confirm cancer recurrence using a safe and minimally invasive procedure. The research will consist of looking for tumor cell(s) circulating in the blood stream and if they are present to characterize them so that more information about the disease can be collected. This information may help us to better understand how to fight cancer.
According to the existing clinical data in our hospital, retrospective study was conducted to screen the risk factors with predictive value for TRC(trastuzumab-related cardiotoxicity) risk, and to construct the risk prediction model for TRC.
