Functional imaging of paragangliomas (PGLs) is not unequivocal. Existing functional imaging modalities show good but variable results in PGLs, warranting the search for additional molecular imaging targets. Investigators aim to evaluate the glucagon-like peptide 1 receptor (GLP-1R) as a novel target for molecular imaging of PGLs. For this purpose investigators will use the tracer 68Ga-NODAGA-exendin 4 for positron emission tomography/computed tomography (PET/CT) imaging.
This study will primarily identify longitudinal associations between cardiorespiratory fitness (CRF) and cognitive function pre- (baseline) to post-chemotherapy (~3 months). This will be a prospective study of 50 BCS. We hypothesize that breast cancer patients undergoing chemotherapy who have higher levels of CRF at baseline will have significantly improved measures of attention, executive function, and memory post-chemotherapy. In addition, the exploratory aims will examine the longitudinal associations between physical activity (PA) and cognitive function from pre- to post-chemotherapy and explore the associations between inflammatory and non-inflammatory biomarkers and CRF...
The purpose of this pilot study will be to provide i) information on feasibility implementing an exercise intervention trial among patients with cutaneous cancers, including melanoma, squamous cell carcinoma (cuSCC), and Merkel cell carcinoma, scheduled to receive checkpoint blockade immunotherapy, and ii) preliminary data on the impact of a day-of-therapy exercise intervention.
The investigators of this study want to see if shortening the total treatment time for brain tumors is safe.The treatment for participant's brain tumors is laser surgery (Laser Interstitial Thermal Therapy (LITT)) followed by radiation with chemotherapy. For participants, the total time of treatment from surgery to the end of radiation and chemotherapy is about l 0 weeks long. This study asks whether it is safe to shorten the total treatment to 7 weeks. To shorten the total treatment time, investigators want to see if it is safe to start radiation with chemotherapy within 5 days after surgery. Usually patients start their radiation with chemotherapy about 21-28 days after the...
The purpose of this study is to explore the experiences and needs of patients with a high-grade glioma and their caregivers. Semi-structured interviews with patients and caregivers will be conducted and analysed using Grounded-Theory approach.
It is planned to integrate various services based on computer vision technologies for analysis of the certain type of x-ray study into Moscow Unified Radiological Information Service (hereinafter referred to as URIS). As a result of using computer vision-based services, it is expected: 1. Reducing the number of false negative and false positive diagnoses; 2. Reducing the time between conducting a study and obtaining a report by the referring physician; 3. Increasing the average number of radiology reports provided by a radiologist per shift.
The goal of this retrospective study is to evaluate the long-term clinical outcomes and complications associated with amygdalo-hippocampectomy using the surgical technique developed by Pr. Coubes (Montpellier, FRANCE). The main questions it aims to answer are: - What are the complications and evolution of clinical outcomes in patients treated with this technique for hippocampal sclerosis or other intern temporal diseases ? - What variables are associated with better seizure control following surgery? Participants include 234 patients treated over the last 30 years at the CHU de Montpellier, FRANCE. The study will analyze clinical data, including seizure...
This research study is studying a drug as a possible treatment for High Grade Meningioma.
To characterize and quantify immune cells expressing the Interleukine 4 induced gene 1 (IL4I1) immunosuppressive enzyme in the blood and in tissue of melanoma patients (primary tumor, sentinel lymph nodes and cutaneous metastases). Then, to compare the results obtained in different clinical settings: - in cases of progression of the disease slower or faster compared to the prognosis established by clinical and pathological data - before and after treatments with immunotherapy (anti Programmed Death ligand 1 (anti-PD1) or anti-PD1 and anti Cytotoxic T Lymphocyte associated protein 4 (anti-CTLA-4)) and / or targeted therapies (BRAF inhibitors and /or...
Rationale: Patients with IDH-wildtype glioblastoma or grade IV IDH-mutant astrocytoma have a very poor prognosis despite standard treatment consisting of surgery, radiotherapy, and chemotherapy. Diffuse infiltration of the brain by the tumor is thought to be one of the main causes of this therapy-resistance. In order to improve the surgical treatment, tumor regions with lower infiltration percentages need to be identified and resected during surgery, a so-called supramarginal resection. Currently, pre-operative T1 contrast enhanced weighted (T1c) MRI is used to identify the tumor for resection. We recently found the combination of apparent diffusion coefficient MRI and...
