Filter by:In some cases of hormone receptor positive, HER2 negative early breast cancer the benefit of adding adjuvant chemotherapy to hormonal treatment, estimated on the basis of the classical clinico-pathological parameters, is unclear. In these cases the application of a genomic test could be useful in guiding the therapeutic choice.
This study is designed to test the feasibility of two intervention on promoting early screening for breast cancer in rural Ghana. In one intervention, screening for breast cancer, diabetes and hypertension will be offered together. In another intervention, a series of sessions with men will be conducted with a goal to change gender attitudes and increase support to women. Our long-term goal is to test these interventions in a large-scale randomized controlled trial. The specific aims of this feasibility study are to: 1) refine the study materials, including the curriculum for the sessions with men, by consulting with an expert advisory committee and a local committee, and 2) determine the feasibility of the two interventions in four clinic zones in Yilo-Krobo district in eastern Ghana (1 clinic in control, 1 clinic in the first intervention, and 2 in the second intervention). This trial registration is for the second specific aim.
This study evaluates the acute toxicity and feasibility of repeat breast conserving therapy with preoperative accelerated partial breast re-irradiation (PAPBI) in female patients aged 51 years or older with ipsilateral recurrent or second primary low-risk breast cancer.
To explore a reasonable and effective way to reduce the incidence of grade 3 or above diarrhea caused by pyrotinib
This is an exploratory phase II interventional study that initiates standard-of-care anti-estrogen treatment preoperatively for 4-12 weeks (+/- 2 weeks).
This study explores the overall feasibility, impact, and satisfaction of using the "mHealth app" on clinic workflow for Black or African American women diagnosed with breast cancer. The "mHealth app" which can be used as a platform to share clinical trial education and communication, was created and tested in previous steps of this study.
To improve the health and quality of life of breast cancer (BC) patients, researchers are focusing on prehabilitation strategies like physical exercise, preparing patients both mentally and physically for clinical and surgical procedures, potentially reducing complications. Physical exercise is also recognized as pivotal in optimizing chemotherapy. It can improve blood flow and oxygen supply in the microenvironment of the tumor (MT), potentially enhancing chemotherapy effectiveness. Although previous research has shown the benefits of preoperative exercise combined with chemotherapy in various cancer types, including BC, further investigation is needed into the exact effects of prehabilitation exercise (PE) on MT physiology. This study aims to provide valuable insights into the potential benefits of PE for BC patients and its impact on the tumor microenvironment. The hypothesis is that PE in BC patients will improve their quality of life, reduce fatigue, increase muscle mass, decrease fat mass, and enhance physical fitness. Additionally, beneficial acute hemodynamic changes, particularly increased blood flow following PE sessions, and hemodynamic adaptations involving higher levels of oxygenated hemoglobin, increased blood flow, greater oxygen saturation, and a higher metabolic rate of oxygen, are expected. The study will include 76 participants aged 18-65 years, meeting specific criteria such as a diagnosis of hormone receptor-positive BC, no medical contraindications for exercise, no metastatic cancer, and no structured exercise in the last six months. These participants will be randomly assigned to a PE group or a control group. The study will consist of three phases: Phase 1 involves pre-intervention assessments, Phase 2 includes a 4-week PE intervention with three weekly sessions, and Phase 3 encompasses post-intervention and post-surgery assessments. The 4-week PE intervention in Phase 2 will include strength and aerobic training. Quality of life and fatigue assessments will use questionnaires, and measurements will be made for fat mass, lean mass, bone density, and cardiorespiratory fitness. Strength measurements will be taken, and shoulder mobility will be evaluated. Hemodynamics of the MT will be assessed using a hybrid device combining Near-Infrared Spectroscopy and Diffuse Correlation Spectroscopy with ultrasound.
Currently, F-18 FDG PET/CT is routinely used for breast cancer staging and treatment response assessment. Most breast cancers express Estrogen Receptor (ER) and Progesterone Receptor (PR) and this subtype shows lower activity on FDG imaging. 68Ga DOTATATE PET/CT is an effective imaging option for somatostatin receptor (SSTR) positive neuroendocrine tumors. There are case reports showing 68Ga DOTATATE uptake in non-Hodgkin lymphoma, meningioma, breast cancer, thyroid adenoma and papillary carcinoma. There are also histochemical studies showing that SSTR is a potential radiopharmaceutical target for ER+/PR+ breast cancer . Its hypothesized that 68Ga DOTATATE PET/CT may be superior to 18F FDG PET/CT primarily in hormone receptor (HR) positive breast cancer. In this study, its aimed to compare the uptake pattern of breast cancer lesions and HR status with 68Ga DOTATATE and 18F FDG uptake in lesions.
Long non-coding RNAs (lncRNAs) play an important role in different types of cancer, including breast cancer, through regulation of gene expression and epigenetic signatures. Genetic variations such as single nucleotide polymorphisms (SNPs) in lncRNAs have been found to be associated with cancer. Our aim was to provide information about the role of LINC00511 SNPs (rs11657109 or rs17780195 or rs9906859, rs4432291 and rs1558535) in breast cancer susceptibility in the Egyptian population.
The aim of this trial is to explore the real-world effectiveness and poteintial predictors of Sacituzumab Govitecan in Chinese metastatic breast cancer patients.
