Clindamycin and Triamcinolone in People With Glioblastoma to Prevent Skin-Related Side Effects of Tumor Treating Fields
The participants are being treated with Tumor Treating Fields (TTFields) for malignant glioma, and this type of treatment may cause skin-related side effects. This study will test whether using clindamycin and triamcinolone topical lotions can prevent skin-related side effects of TTFields.

Clinical Applicantion of Multi-Tracer PET/MR Imaging in Neurological Disorders/Disease
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.

Clinical Application of the J-PET Scanner Prototype
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...

Clinical, Laboratory, and Epidemiologic Characterization of Individuals and Families at High Risk of Melanoma
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...

Clinical, Radiological, Histologic and Molecular Features of a Cohort of Melanocytic Tumors of the Central Nervous System
Primary melanocytic tumors of the central nervous system are rare lesions and occur develop from leptomeningeal melanocytes. The WHO classification of tumors of the central nervous system in its most recent version (2021) distinguishes on the one hand the circumscribed melanocytic tumors including melanocytoma, benign, and its slope malignant, meningeal melanoma, with an intermediate grade lesion in between, called intermediate grade melanocytoma. They are to be distinguished from diffuse tumors or multifocal diseases such as melanocytosis and its malignant corollary, melanomatosis. The main current challenge is to distinguish them from their differential diagnoses,...

Clinical Relevance of Detecting Molecular Abnormalities in Glial Tumor Exosomes
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.

Clinical Safety Study on 5-Aminolevulinic Acid (5-ALA) in Children and Adolescents With Brain Tumors
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.
