This clinical trial studies the use of 7-Tesla (7T)and 3T magnetic resonance imaging (MRI) in detecting brain diseases. 7T MRI has increased detection sensitivity, including more accurate lesion delineation, higher inter-rater agreement. Diagnostic procedures such as 7T MRI may help ultimately improved diagnostic and therapies confidence to inform decision making than standard 3T MRI.
This registry aims to collect clinical and radiologic information including detailed clinical, conventional MR and advanced MR imaging data of patients with brain gliomas. Advanced MR imaging may include diffusion-weighted imaging, perfusion-weighted imaging (dynamic susceptibility contrast, arterial spin labeling, dynamic contrast enhancement), and chemical exchange saturation transfer (CEST) imaging. This registry will describe course of disease and long-term outcomes of brain gliomas.
Endocrine therapy (ET) is widely used to treat hormone receptor positive breast cancer and prevent recurrence by downregulating estrogen function. However, ETs readily cross the blood brain barrier and interfere with the action of estrogen in the brain. Estrogen supports cognition and menopausal status is closely linked to cognitive health in women. This has raised concern that anti-estrogen ETs may affect cognition and brain health in breast cancer survivors. However, evidence across existing studies is inconsistent and these effects remain poorly understood. The incomplete understanding of the effects of ET are likely due to limitations of earlier studies - namely, the...
A biomarker is a measurable indicator of the severity or presence of some disease state. In this study, brain metastases patients who will be receiving radiation treatment, will undergo CT (Computed Tomography) and MRI (Magnetic Resonance Imaging) scans prior to and after radiation treatment to measure these biomarkers. This is a single-center phase II study to validate the predictive abilities of biomarkers, in terms of determining how patients will respond to radiation treatment.
This study is the experimental study for brain metastasis development mechanism in patients with breast cancer with brain metastasis
This study is a single-center, prospective, single-arm clinical trial, which intends to enroll patients with triple-negative breast cancer with brain metastases to receive ivonescimab combined with TROP2 ADC (such as sacituzumab govitecan) treatment until disease progression, intolerable toxicity, withdrawal of informed consent, or the investigator deems it necessary to discontinue the medication, and to collect data on the drug's efficacy and safety.
The survival of children, adolescents and young adults (AYA) with acute leukemia has improved dramatically over the last two decades. This success is a result of using multiple chemotherapy drugs in combination, with the inclusion of drugs that enter the brain and prevent leukemia cells from growing there. Studies in these cancer survivors have shown that the exposure to these chemotherapy drugs can lead to risks for impaired brain function, also referred to as neurocognitive side effects of chemotherapy. There is an opportunity to identify participants at risk for these side effects and to prevent their development. The purpose of this study is to incorporate a brain imaging tool...
Anti-CASPR2 limbic encephalitis (CASPR2-LE) is a rare neurological disorder primarily affecting males over the age of 50. It is mediated by an autoimmune antibody response in the central nervous system (CNS) against the cellular adhesion molecule contactin-associated protein-like 2 (CASPR2). This protein plays an important role in the trafficking of KV1 channels under the myelin sheath in the juxtaparanodal region of myelinated axons. It is mostly present in the neurons of the limbic system, basal ganglia, and other motor related and sensation areas (Qin, Yang, Zhu, Wang, & Shan, 2021). This distribution explains the diverse clinical manifestations of the disease, primarily...
Interactions between the perceptual and motor systems are fundamental to the performance of complex motor tasks and are at the heart of the fine motor control required for the production of complex sounds such as speech production or playing a musical instrument. In such situations, the brain must learn to generate relevant motor commands to a sound-producing system with fixed physical characteristics, such as the vocal tract or a musical instrument. No study has yet been able to directly test the dynamic aspect of this sensorimotor learning in an acoustic production task with fine motor control. The Adolphe de Rothschild Foundation Hospital takes care of patients requiring...
This biospecimen collection study will evaluate the feasibility of engrafting and testing resected Central nervous system (CNS) tumors tumor tissue ex vivo to estimate drug response, in pediatric and adult subjects. CNS tumors display remarkable heterogeneity and unfortunately there are no reliable precision oncology platforms that can identify the most effective therapy for each patient. Recent work has demonstrated the success of functional precision oncology platforms using patient-derived explant (PDE) at predicting drug response in various cancers. Since PDEs maintain important aspects of tumor heterogeneity they may prove effective as functional models for CNS tumors. The...
