Filter by: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, namely metastasis of a cutaneous or extrac-cutaneous melanoma mainly and on the other hand other pigmented entities occuring in the CNS such as malignant melanic tumor of the peripheral nerve sheath (MMNST, formerly "melanotic schwannoma").

This biospecimen collection study will evaluate the feasibility of engrafting and testing resected Central nervous system (CNS) tumors tumor tissue ex vivo to estimate drug response, in pediatric and adult subjects. CNS tumors display remarkable heterogeneity and unfortunately there are no reliable precision oncology platforms that can identify the most effective therapy for each patient. Recent work has demonstrated the success of functional precision oncology platforms using patient-derived explant (PDE) at predicting drug response in various cancers. Since PDEs maintain important aspects of tumor heterogeneity they may prove effective as functional models for CNS tumors. The purpose of this study is to explore the feasibility of using a novel PDE platform to generate drug sensitivity scores from patients with central nervous system tumors in Pediatric and adult subjects having low- or high-grade CNS tumors resected. The secondary objective is to estimate the proportion of successfully scaled PDEs generated per given tumor size.
The goal of this observational study is to evaluate disease-free survival (DFS) in patients with malignant gliomas undergoing neurosurgical procedures using 5-aminolevulinic acid (5-ALA)-based photodynamic therapy
Retrospectively analyzing the epidemiological and clinical characteristics, treatment, recurrence, prognosis and prognostic factors of the germ-cell tumors of central nervous system in a single center.
Loc3CAR is a Phase I clinical trial evaluating the use of autologous B7-H3-CAR T cells for participants ≤ 21 years old with primary CNS neoplasms. B7-H3-CAR T cells will be locoregionally administered via a CNS reservoir catheter. Study participants will be divided into two cohorts: cohort A with B7-H3-positive relapsed/refractory non-brainstem primary CNS tumors, and cohort B with brainstem high-grade neoplasms. Participants will receive six (6) B7-H3-CAR T cell infusions over an 8 week period. The purpose of this study is to find the maximum (highest) dose of B7-H3-CAR T cells that are safe to give patients with primary brain tumors.
This is a Phase 1 study of central nervous system (CNS) locoregional adoptive therapy with SC-CAR4BRAIN, an autologous CD4+ and CD8+ T cells lentivirally transduced to express to express combinations of B7-H3, EGFR806, HER2, and IL13-zetakine chimeric antigen receptors (CAR). CAR T cells are delivered via an indwelling catheter into the ventricular system in children and young adults with diffuse intrinsic pontine glioma (DIPG), diffuse midline glioma (DMG), and recurrent or refractory CNS tumors. A child or young adult meeting all eligibility criteria, including having a CNS catheter placed into their ventricular system, and meeting none of the exclusion criteria will have their T cells collected. The T cells will then be bioengineered into a second-generation CAR T cell that target B7H3, EGFR806, HER2, and IL13-zetakine on tumor cells. Patients will be assigned to 1 of 2 treatment Arms based on the type of their tumor: - Arm A is for patients with DIPG (meaning primary disease localized to the pons, metastatic disease is allowed) anytime after standard radiation OR after progression. - Arm B is for patients with non-pontine DMG (meaning DMG in other parts of the brain such as the thalamus or spine) anytime after standard radiation OR after progression. This Arm also includes other recurrent/refractory CNS tumors.
A Multi-center, Non-Randomized, Open-Label Phase 2 Basket Clinical Trial to Evaluate ICP-723 in Patients with Advanced Solid Tumors or Primary Central Nervous System Tumors
This phase I trial studies the impact of taking drugs (agents) that target altered brain metabolism following standard of care brain radiotherapy. Radiotherapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. However, radiotherapy can also cause harmful effects to normal brain functioning. One drug, called anhydrous enol-oxaloacetate (AEO), has previously been studied in ischemic stroke, Alzheimer's disease, Parkinson's disease, and glioma. Drugs such as AEO may help preserve or restore healthy brain function after brain radiotherapy compared to the standard practice which consists of no drugs.
Central nervous system (CNS) tumors are the most common solid malignancies among children. Although some types of CNS tumors like medulloblastomas and low-grade gliomas are widespread and well-studied, there is a huge number of rare diseases that need further research. This international registry aims to establish a large multicenter database of pediatric and young adult patients with rare embryonal tumors of the central nervous system and describe the clinical presentations, diagnostics, treatment regimens, and outcomes. Embryonal tumors with multilayered rosettes (ETMR), FOXR2-activated CNS neuroblastoma, cribriform neuroepithelial tumor, and CNS tumor with BCOR internal tandem duplication are extremely rare embryonal tumors some of which were first described in the last edition of the World Health Organization (WHO) Classification of Tumors of the Central Nervous System. Objectives of the registry are 1) to evaluate prognostic factors, 2) to identify diagnostic and treatment gaps, 3) to investigate the characteristics and outcome of the disease with different treatment regimens, and 4) to generate data-based prospective diagnostic and treatment recommendations.
