Active clinical trials for "Breast Neoplasms"

This is a data-driven, retrospective, longitudinal, population- based, observational, multi-centered study using secondary data captured from congruent electronic health records (EHRs).

The aim of this study is to understand the strategies for adapting postural control in patients who have received chemotherapy treatment for gynaecological cancer.

This phase I trial evaluates how well a mobile device-based breast cancer survivorship interactive care plan works in monitoring symptoms and recovery in patients with stage 0-III breast cancer. The interactive care plan provides patients with individualized, 'just in time' education materials to promote self-management for those reporting difficult to control symptoms, as well as escalations to contact their care team for signs or symptoms concerning for cancer coming back (recurrence). The interactive care plan may help alleviate the symptoms of fatigue, insomnia, hot flashes, and sexual dysfunction; increase physical activity level and improve quality of life in patients with breast cancer.

Neoadjuvant chemotherapy (NAC) is the first line treatment for locally advanced breast cancer (BC). Besides making breast conserving surgery feasible, its main aim is to achieve a pathological complete response (pCR). Previous studies demonstrated that a pCR correlated with a higher disease-free survival. Tumor response may vary among different BC subtypes and only 30% of BC respond completely to NAC. Treating chemo-resistant disease with NAC may cause patient harm due to drug toxicity and surgery delay. It is therefore very important to promptly identify those women who will not benefit from NAC. Mammography and ultrasound proved ineffective in monitoring changes in lesion size due to therapy-induced fibrosis. MRI is the most accurate imaging technique for assessing early clinical response by measuring tumor size, however its accuracy is lower post NAC. This necessitates the need for a new technique able to non invasively assess the effectiveness of NAC. Optical techniques are sensitive to the biological changes that occur within the tumor after NAC administration. These changes occur prior to tumor size reduction. Optically estimated total hemoglobin concentration correlates with the histological analysis of vasculature as well as with tumor-associated angiogenesis which can affect tumor changes during NAC. Other promising biomarkers related to tissue composition (water, lipid, collagen content) and structure (scattering) may also be evaluated by optical techniques. The aim of the study is to monitor the effectiveness of NAC in BC patients with a near infrared spectroscopic imaging platform which allows to non-invasively detect changes in vascularization and size of BC and to characterize the presence of temporal changes in regional concentrations of relevant biomarkers (oxy- and deoxyhemoglobin, water, lipid and collagen concentration, scattering) within tissue during NAC. This optical imaging technique will provide a non-invasive, safe and relatively inexpensive tool to monitor patients' response to NAC and to predict their outcome.

This study investigated the feasibility of the novel modular mobile health (mHealth) for personalized rehabilitation and explored the participants' satisfaction and app data during treatment of breast cancer.

Heterogeneity of 18F-fluorodeoxyglucose (FDG) uptake is a promising marker for predicting response to treatment. This study aimed to evaluate the ability of pretreatment positron emission tomography/computed tomography (PET/CT) 18F-FDG-based heterogeneity to predict the response to pyrotinib in patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC).

This is a transversal monocentric study comparing two groups of women (group 1, patient group : patients who have been treated for a breast cancer with taxane-based chemotherapy ; group 2, control group : healthy volunteers). The aim of this study is to evaluate if a difference exists regarding the maximal isometric muscle strength between group 1 and 2.

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.

retrospective non-interventional study (NIS) that aims to describe the demographics, clinical characteristics, clinical outcomes, and treatment patterns, among patients receiving palbociclib for the treatment of HR+/HER2- metastatic/locally advanced breast cancer (BC)

The purpose of this study is to observe the routine clinical care of patients who have been diagnosed with breast cancer and have undergone Guardant360 testing.
