Amino acid PET imaging could represent a biomarker for the evaluation of IDH inhibitor treatments for patients with refractory IDH-mutated gliomas
Glioblastoma (GBM) is the most common and aggressive primary tumor of the adult central nervous system (CNS), with a poor prognosis and median overall survival ranging between 14 to 20 months despite advancements in diagnostic and therapeutic strategies. This prospective, observational, multicenter study aims to collect and analyze comprehensive data from GBM patients treated across selected centers in Europe and the United States, the investigators' centers included. Information will include demographics, imaging findings, molecular subtypes, clinical status, surgical strategies, postoperative management, complications, and follow-up data. Patients over 18 years old...
This clinical trial focuses on pediatric patients aged 2 up to 18 years of age with a new or recurrent pediatric brain tumor, suspected to be either a high-grade or low-grade glioma, and scheduled for surgical removal. 5-aminolevulinic acid (5-ALA) is FDA-approved for improving brain tumor visualization in adults during surgery through fluorescence, enabling more complete removal of the tumor. This study aims to evaluate the feasibility of administering 5-ALA to pediatric brain tumor patients and to assess the quality of tumor fluorescence during surgery in this patient population. For the clinical trial, the patient will orally ingest 5-ALA 6 to 12 hours before brain surgery....
The goal of this Study is to evaluate the effectiveness and safety of Vorasidenib in Patients with Isocitrate dehydrogenase IDH1/2 mutant Grade 2 astrocytoma or oligodendroglioma, primary purposeis to evaluate the efficectiveness of Vorasidenib in glioma patients treated in routine clinical practice in In China, patients aged 12 and above with grade II or higher astrocytoma or oligodendroglioma with IDH1 or IDH2 mutations. The main question it aims to answer is: if this trend is consistent with the efficacy observed in the INDIGO study, and there is not any new safety signal compared to previous research data? Researchers will compare to no treatment. Participants is not...
Using excess tumour samples that contain amyoid, from patients with Medullary Thyroid Cancer, we aim to determine the structures of ex vivo amyloid fibrils from human tumour tissue samples and compare them with that of existing stock of in vitro formed amyloid fibrils. This will permit the analysis of the effects of gene mutation and post-translational modification on the development of amyloid from a disease state. Amyloid is known to accumulate in the brain tissue of patients with neuro-degenerative conditions such as Alzheimer's disease and Dementia. Therefore solving the structure of amyloid fibrils may aid the development of future treatments for these conditions.
This clinical study aims to evaluate the tolerability, safety, and efficacy of Anbal-cel in patients with recurrent or refractory PCNSL or SCNSL. Subjects who have provided written consent and meet the inclusion and exclusion criteria through screening evaluations will undergo leukapheresis (LP) for Anbal-cel manufacturing. Subjects whose collected nucleated cells are confirmed suitable for Anbal-cel production will be enrolled in the clinical study. Prior to Anbal-cel administration, lymphodepletion therapy will be performed and must be completed at least 2 days before Anbal-cel administration. Anbal-cel will be administered to subjects who meet the inclusion and exclusion...
1. The primary aim of this study is to investigate the correlation between the length of ICU stay and a newly developed FIVE score in neuro-intensive care patients. 2. The secondary objectives are to evaluate the impact of the FIVE score on hospital length of stay, Modified Rankin Scale, and mortality, as well as to determine the correlation between the GCS, FOUR, and FIVE scores
This phase II trial studies how well the addition of 18F-DOPA (amino acid) positron emission tomography (PET)/computed tomography (CT) to standard of care (SOC) imaging can improve the clinical management of patients with brain tumors in over 50% of cases. PET is an imaging test that helps to measure the information about functions of tissues and organs within the body. A PET scan uses a radioactive drug (radiotracer) to show this activity. CT scan uses X-rays to create images of the bones and internal organs within the body. Combining a PET scan with a CT scan can help make the images easier to interpret. PET/CT scans are hybrid scanners that combine both of the two modalities...
There is currently no standard first-line treatment for stage PPGL, and the 5-year survival rate of patients with advanced pheochromocytoma/paraganglioma (PPGL) is low, ranging from 30% to 60%. At present, several domestic teams have carried out clinical studies on the treatment of advanced PPGL with good efficacy. In the early stage, our center used anrotinib to treat advanced PPGL, and the overall effective rate reached 44%. In the early stage, our team used anrotinib combined with PD-1 monoclonal antibody to treat advanced PPGL patients. The effective rate reached 66% (2/3). Therefore, the investigators plan to further conduct prospective studies to explore the efficacy...
This is an observational study in adult males and females utilising skin condition measurements using the LumAssure Raman device. Data will be used to determine accuracy under the ROC curve (AUCROC) of the LumAssure device for differentiating between benign and cancerous skin conditions. The measurements will provide data which will be used to establish spectral parameters for different skin conditions. Measurements will be benchmarked against diagnoses from medical specialists, and when available confirmed with histological data. The main question it aims to answer is : What is the accuracy, in terms of the area under the ROC curve (AUCROC) of the LumAssure device for...
