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 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.
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...
A study on the safety and efficacy of T-DXd in combination with local radiotherapy for brain metastases in HER2-Positive and HER2-Low breast cancer patients.
Exploring the effect of supplementation with daily addition of prebiotic dried chicory root (WholeFiberTM) for 6 weeks on fecal SCFA levels, gut microbial composition and immune cell composition in minimal stage II A melanoma patients following surgical treatment.
Autoimmune gastritis (AIG) is a chronic autoimmune disorder characterized by parietal cell destruction and oxyntic mucosal atrophy, leading to achlorhydria and intrinsic factor deficiency. These pathological changes impair iron and vitamin B12 absorption, resulting in iron-deficiency anemia, pernicious anemia, and neuropsychiatric manifestations. Notably, 4-12% of AIG patients develop type 1 gastric neuroendocrine tumors, while facing a 3-7 fold increased risk of gastric adenocarcinoma with an incidence of 0.9-9%. Current management of AIG is limited to iron and vitamin B12 replacement, as no disease-modifying therapies exist. The progressive hypochlorhydria reduces...
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...
This study seeks to determine the impact of focused ultrasound (FUS) on the composition of the tumor extracellular microenvironment. Researchers will evaluate regions that are very abnormal, as well as regions that have less evidence of disease. A sub-portion of each of these areas will be targeted by focused ultrasound. Microdialysis catheters will then be placd into each region that has and has not been exposed to FUS (total of 4 catheters) to determine how FUS impacts the the brain and tumor extracellular metabolome, including concentration of routine drugs systemically administered prior to, and during surgery. Researchers hope that this information will help reveal the...
EVIDENT's aim is to test if ex vivo drug screening can predict whether patients with solid cancers will respond, or not respond, to standard care treatments. Patients undergoing standard care surgery to excise their tumour, those undergoing a biopsy, or those having a fluid aspirate of a solid tumour with surplus tissue available after diagnostic use will be eligible for this study. The specimen will then be assessed with ex vivo drug screening utilising all standard therapies and therapies that are more novel and in early stages of development. The results of the ex vivo drug screen will be compared to the cancer's actual response to standard care treatments for those...
