Filter by:The goal of this interventional study is to evaluate the risk of atrial fibrillation (AF) and other cardiac arrhythmias and diseases in breast cancer patients treated with radiation therapy (RT). In addition to regular follow-up of patients by the radiation oncologist for 5 years, cardiovascular screening at the end of follow-up, combining the use of a connected watch and a cardiological check-up, could make it possible to identify precisely the types and frequencies of these sometimes asymptomatic, and probably underestimated, cardiac diseases. The main questions it aims to answer are: - To assess the incidence of AF and other cardiac arrhythmias and diseases occurring within 5 years after RT - To evaluate absorbed doses in the heart and cardiac substructures (chambers, conduction nodes, coronaries, pulmonary veins) based on auto-segmentation models developped with deep learning algorithms - To investigate whether the risk of AF and other cardiac arrhythmias and diseases is associated with cardiac irradiation characterized by these absorbed doses (dose-response relationship) Participants will be included between 2023 and 2025, 5 years after their RT: - Retrospective data collection will be based on a medical questionnaire designed to identify cardiac pathologies present prior to RT and those having occured in the past, between RT and 5 years post-RT. - Cross-sectional data collection will be based on screening for cardiac pathologies using a connected watch worn for 1 month (silent AF screening) and a cardiology consultation (including ECG and echocardiography) to identify cardiac pathologies at 5 years post-RT possibly not identified in the retrospective data collection.
The advances in early detection coupled with improvements in treatments have led to an ever increasing number of breast cancer survivors. New methods to improve outcomes, including strategies aimed at improving the quality of life and reducing the risk of other diseases, may complement the currently available treatment options. In particular, interventions targeting diet, weight and physical activity can reduce the risk of cancer occurrence, prevent cancer recurrence, and improve survival and the quality of life.This cross-sectional, prospective, observational study aims at evaluating dietary habits and nutritional knowledge in patients with early hormone receptor positive and hormone receptor negative breast cancer.
The goal of this interventional study is to optimize the protocol of FES PET/CT in Estrogen Receptor positive Breast cancer patients with Brain metastases. Patients will undergo MRI of the brain and FDG PET/CT brain as part of standard of care for radiation treatment planning. An additional 18F-FES PET/CT brain scan will be completed before this standard of care radiation treatment. Patients will be followed prospectively with clinical and MRI assessments per standard-of-care for a total of 12 months. Study Population: Patients with ER-positive breast cancer with biopsy proven or suspected new or recurrent brain metastases (based on standard of care MRI) planned for radiation treatment of brain lesions.
This is a multicenter randomized, open label study to evaluate overall survival with the Bria-IMT regimen in combination with Checkpoint Inhibitor [Retifanlimab], versus Treatment of Patients'/Physicians' Choice (TPC) in advanced metastatic or locally recurrent breast cancer (aMBC) patients with no approved alternative therapies available.
Identify and test thresholds, specificity and sensitivity for a potential cancer associated biomarker protein, FGF19, (and associated markers) for detection in human blood in the blood of breast and colorectal in cancer patients, and see if occurs at higher rates than healthy controls
This pilot observational study is being done to identify possible biomarkers of response to endocrine therapy in patients with ER/PR+ metastatic lobular breast cancer (LBC) starting new endocrine therapy. 18F-fluorofuranylnorprogesterone Positron Emission Tomography/Computed Tomography (FFNP-PET/CT) and liquid biopsies will be performed at baseline and after 4 weeks of treatment. Baseline levels and dynamic on-treatment changes in estrogen signaling as measured by FFNP-PET/CT and circulating tumor cell (CTC) liquid biopsy will be correlated with clinical response to endocrine therapy and progression-free survival in the above cohort of patients.
This study aims to assess biomarkers and their related polymorphisms in the context of cancer-associated thromboembolism, with a particular focus on their interaction with the immune system. The roles of immune checkpoints, inflammatory and angiogenesis factors, as well as circulating immune cells will be elucidated. Additionally, our investigation extends to the exploration of long non-coding RNAs (LncRNAs) and genes associated with the coagulation vascular system. Initially, these aspects will be evaluated in the context of colorectal cancer, with the intention to expand our research to other solid tumors. The identification of these biomarkers and genetic factors holds the potential to revolutionize therapeutic approaches for patients with cancer-associated thromboembolism, shedding light on their chemotherapy resistance. The effectiveness of combining immunotherapy with targeted inhibitors like Palbociclib and anticoagulants such as Rivaroxaban, among other potential interventions, will be assessed. This study aims to make significant contributions to the understanding of these critical aspects, ultimately leading to the development of more effective treatment strategies for cancer patients.
This is a phase I open-label dose escalation trial of FWD1802 as monotherapy and in combination with palbociclib in patients with ER+/HER2- unresectable locally advanced or metastatic breast cancer The goal of this clinical trial] is to learn about in ER+/HER2- BC participant population. The main questions it aims to answer are: - Establish the recommended phase II dose (RP2D) and/or the maximum tolerated dose (MTD) of FWD1802 as monotherapy and in combination with palbociclib in patients with ER+/HER2- unresectable locally advanced or metastatic breast cancer. - Explore the safety and tolerability of FWD1802 as monotherapy and in combination with Palbociclib. - Characterise Pharmacokinetics of FWD1802 as monotherapy and in combination with palbociclib. - Explore preliminary efficacy signals.
Contrast-enhanced mammography (CEM) is an emerging breast imaging modality that is based on dual-energy mammography and the injection of iodinated contrast agent. A typical CEM study consists of a low-energy image (equal to a FFDM image) and a recombined image (in which areas of contrast enhancement can be appreciated). However, the situation can occur that lesions are visible only on the recombined (contrast) images (in this protocol defined as 'recombined-only lesions' or ROLs). In these cases, radiologists need to perform 'contrast-enhanced stereotactic biopsy' (CESB), in which CEM is used as a targeting modality. However, experiences with CESB are still limited and one of the most urgent questions that need to be answered is the amount of tissue sampling that is required to reach a final diagnosis. The investigators aim to study where the cut off will be in terms of tissue sampling volume needed (i.e., number of biopsies) for a reliable diagnosis.
The aim of this study is to evaluate the efficacy and safety of contrast-free magnetic resonance angiography (MRA) for deep inferior epigastric perforator flap planning. The investigators propose to perform a non-contrast MRA to achieve the following extremely important objectives: to avoid radiation exposure, minimize the risk of potentially harmful effects of contrast agents, and reduce the cost of the study.The investigators assume that the use of non-contrast MRA following our protocol including certain patient's positioning, a special pulse scanning sequence and perforators' projection method is effective and allows mapping of perforators without injecting a potential harmful contrast agent.
