This first-in-human study will establish the human safety and radiation dosimetry of the system A amino acid transport substrate, (R)-3-[F-18]fluoro-2-methyl-2-(methylamino)propanoic acid ([F-18]MeFAMP), for positron emission tomography (PET) imaging of primary and metastatic brain tumors. This study will include 3 cohorts: healthy volunteers for whole body dosimetry estimates (n=6-8, Dosimetry Cohort), patients undergoing evaluation for recurrent high grade glioma after radiation therapy (n=10, high grade glioma (HGG) Cohort), and patients with brain metastases from extra-cranial solid tumors before and after radiation therapy (n=10, Metastasis Cohort). Exploratory assessment of...
This study is designed as an open-label, prospective, single-arm, single-center trial aimed at evaluating the efficacy and safety of MTX or Thiotepa combined with Orelabrutinib and standard chemotherapy regimens in the treatment of DLBCL patients with central nervous system involvement.
Cancer-related fatigue is a common and debilitating late effect in pediatric brain tumor survivors. Currently, evidence-based recommendations to ameliorate this condition are lacking. The researchers will investigate the ability of methylphenidate to improve fatigue and cognition in pediatric brain tumor survivors suffering from cancer-related fatigue. Methylphenidate is a drug (central nervous stimulant) most commonly used in the treatment of hyperkinetic disorders such as attention-deficit/hyperactivity disorder (ADHD). If methylphenidate shows an effect, the prospects are important for this patient group, since methylphenidate may then be included as part of the treatment...
Multimorbidity (the presence of two or more coexisting long-term conditions) is a significant challenge facing the NHS, especially given UK's ageing population and the association with high levels of illness burden and healthcare costs. Over 50% of adults >65 years have multiple long-term conditions (MLTCs). Our group has validated a broad range of algorithms applied to single wearable sensors that have the potential to capture walking-related mobility outcomes (such as walking cadence and walking speed) accurately and reliably during activities of daily living across five single long-term conditions. These algorithms, however, cannot be readily applied to people with MLTCs...
The goal of this single centre pilot study is to explore whether 18F-fluoro-ethyl-tyrosine PET (FET-PET) yields comparable findings to 11C-methionine PET (Met-PET) for the localisation of pituitary tumours.
Evaluate the Efficacy and Safety of R-CHOP-MTX±Zanubrutinib in Newly Diagnosed Diffuse Large B-Cell Lymphoma Patients with Central Nervous System Involvement, and Explore the Efficacy Indicators of CSF-ctDNA.
This study is designed to evaluate the role of Oxygen Enhanced (OE) Magnetic resonance imaging (MRI) and Blood Oxygenation Level Dependent (BOLD) MRI in detecting regions of hypoxic tumour and to evaluate their use as imaging methods to selectively deliver targeted radiotherapy to regions of aggressive disease.
The primary objective of this study is to demonstrate the non-inferiority of cCeLL compared to frozen section analysis. The investigational device is intended for use with indocyanine green (ICG) for fluorescence imaging as an aid in the visualization of vessels (micro- and macro-vasculature) blood flow in the cerebrovascular before, during or after cranial diagnostic and therapeutic procedures, such as tumor biopsy and resection, which is then read and analyzed by trained-professional for intraoperative diagnosis. The comparison will be held by the device with the conventional intraoperative histological frozen section analysis of identical brain tissue samples in the...
The goal of this nationwide, multicenter observational study is to develop and externally validate multimodal large models that can (1) predict the risk of brain metastases and (2) estimate long-term prognosis in patients with non-small cell lung cancer (NSCLC). The main questions it aims to answer are: - Can a multimodal large model that fuses imaging, pathology, genomic, and clinical data accurately identify NSCLC patients at high risk of developing brain metastases? - Can a multimodal large model reliably forecast intracranial progression-free survival, progression-free survival, and overall survival across diverse real-world treatment settings? (ie,...
Participation in medical trials usually favors a particular demographic group. But there is limited research available to explain what trial attributes affect the completion of these specific demographic groups. This trial will admit a wide range of data on the clinical trial experience of glioma patients to determine which factors prevail in limiting a patient's ability to join or finish a trial. It will also try to analyze data from the perspective of different demographic groups to check for recurring trends which might yield insights for the sake of future glioma patients.
