This is an prospective study to evaluate the safety and efficacy of naxitamab monotherapy or combined with chemotherapy or combined with chemotherapy and checkpoint inhibitor in the treatment of pediatric high-risk and refractory/relapsed neuroblastoma in Sun Yat-sen University Cancer Center.
The goal of this clinical trial is to learn about the application of domestic PET/MR in major brain diseases. The main questions it aims to answer are: - Overcome the bottleneck of early accurate diagnosis and treatment in major brain diseases clinical practice. - Promote the clinical application of domestic PET/MR, enhance international competitiveness. Participants will have a PET/MR scan of the brain.
The goal of this clinical trial is to evaluate the diagnostic efficacy of somatostatin receptor and norepinephrine transporter targeted imaging (including 18F-MFBG, 123I-MIBG, 131I-MIBG, 68Ga-DOTA-NOC, 68Ga-DOTA-TATE, 68Ga-DOTA-TOC, and other radiolabeled somatostatin analogues) in the diagnosis and staging of neuroblastoma and pheochromocytoma/paraganglioma patients aged 1-70 years. The main questions it aims to answer are: Can molecular targeted imaging using various norepinephrine transporter tracers (18F-MFBG, 123I/131I-MIBG) and somatostatin receptor tracers (68Ga-DOTA-peptides series) accurately detect primary tumors and metastatic lesions in...
Positron emission tomography (PET), an advanced diagnostic imaging technique, exploits the annihilation of positrons (e+) to delineate pathological alterations within diseased tissues. Integral to PET scanners are detector systems that transform gamma photons into fluorescent photons, thereby gleaning insights into the energy, time, and spatial distribution of gamma photons emanating from positron-emitting radiopharmaceuticals. Conventional PET scanners, bear a significant financial burden primarily due to their reliance on LSO (lutetium oxyorthosilicate) or LYSO (lutetium yttrium oxyorthosilicate) scintillation crystals. The exorbitant cost and limited availability of these...
The goal of this prospective observational study is to evaluate the diagnostic performance of ¹²³I-MIBG SPECT/CT and SSTR PET in Chinese children with suspected or confirmed neuroblastoma (NB). The main questions it aims to answer are: - What are the sensitivity and specificity of each modality-alone and combined-for initial staging and for detecting relapse or metastasis? - Can SSTR-targeted PET reliably identify MIBG-negative NB lesions and help select candidates for peptide-receptor radionuclide therapy (PRRT)? Pediatric patients (≤18 years) undergoing routine evaluation for NB will receive both imaging studies; results will be correlated with...
A prospective, open-label, phase 1 study. This clinical trial aims to evaluate the diagnostic value of 68Ga-XT771, a CAIX/CAXII protein-specific probe, in PET/CT imaging for patients with clear cell renal cell carcinoma and glioblastoma. Safety, tolerability, and biodistribution characteristics of 68Ga-XT771 will also be assessed.
This study will investigate how genetic and environmental factors contribute to the development of melanoma, a type of skin cancer, and related conditions. Individuals >=4 weeks with a personal or family history of melanoma or atypical spitzoid/Spitz tumor may be eligible for this study. Participants will: - Fill out one or two questionnaires about their personal and family medical history. - Provide written consent for researchers to review their medical records and pathology materials related to their care and those of deceased relatives with melanomas, tumors, cancer, or other related illnesses for whom they are the next-of-kin or legally authorized...
Data involving orthopaedic conditions and rehabilitation aspects of musculoskeletal and neuromuscular disorders will be collected and stored as part of the normal clinical care of patients seen in the University of Florida (UF) and Shands Orthopaedics and Sports Medicine Institute.
The purpose of this pilot study is that exosomes constitute a more interesting support for analyzes allowing a broader screening of molecular alterations to be carried out with more reliable, more sensitive and more efficient results than the reference Foundation One Liquid CDx test.
In this prospective, open, single-armed, multicenter, phase II study for application of 5-ALA in children and adolescents with brain tumors 80 patients will be investigated. Primary objective of the study is to determine the safety of 5-ALA for fluorescence-guided resections in children and adolescents with intra-axial brain tumors. Secondary objectives are - to determine whether fluorescent tissue truly signifies tumor (positive predictive value) in various pediatric brain tumors - to determine the degree of tumor resection on early post-operative MRI - and to determine the pharmacokinetics of 5-ALA in this population.
