Filter by:At the center of pediatric oncology in Copenhagen the investigators experience that the children with brain tumor, more or less have a healthy body with normal skeletal muscle mass and are physical active to the same level as their friends at the same age. The treatment period for brain tumor is approximately two years. After the treatment period, the children are more sedative with less interest in coming out doing physical activities and thus the investigators suspect that they have altered hormonal response, low skeletal muscle mass and perhaps are in risk of developing metabolic syndrome. By comparing children with newly diagnosed CNS tumor with children finished treated for CNS tumor, we wish to describe the metabolic path during the approximately two years treatment period these children go through. These results will also be compared with results from healthy controls. The investigators aim to include 10 children (aged 6-18 years) with newly diagnosed CNS tumor, 10 children (aged 6-18 years) finished treated for CNS tumor and 10 healthy controls (aged 6-18 years). By using stable isotope technique the investigators will investigate systemic fat, glucose and protein metabolism together with liver protein degradation and glucose production. Furthermore, by using DXA scan the investigators will describe the quality and distribution of skeletal muscle. Lastly, the investigators will determine the skeletal muscle signal pathway and metabolism in skeletal muscle via the Bergström biopsy technique in vastus lateralis.
Background: About 90,000 new cases of brain and spinal cord tumors are diagnosed annually in the United States. Most of these tumors are benign; however, about 30% are malignant, and 35% of people with malignant tumors in the brain and spinal cord will die within 5 years. Many of these people have changes in certain genes (MYC or MYCN) that drive the development of their cancers. Objective: To test a study drug (PLX038) in people with tumors of the brain or spinal cord. Eligibility: People aged 18 years or older with a tumor of the brain or spinal cord. Some participants must also have tumors with changes in the MYC or MYCN genes. Design: Participants will be screened. They will have a physical exam and blood tests. They will have imaging scans and a test of their heart function. They may need to have a biopsy: A sample of tissue will be removed from their tumor. PLX038 is given through a tube attached to a needle inserted into a vein in the arm. All participants will receive PCX038 on the first day of each 21-day treatment cycle. They will take a second drug 3 days later to help reduce the risk of infection; for this drug, participants will be shown how to inject themselves under the skin at home. Blood tests, imaging scans, and other tests will be repeated during study visits. Hair samples will also be collected during these visits. Some participants may have an additional biopsy. Study treatment will continue up to 7 months. Follow-up visits will continue every few months for up to 5 years.
This study explores how microorganisms in the gut can affect the growth and progression of brain tumors.
The purpose of this study is to find out whether avutometinib is a safe treatment for advanced or recurrent solid tumor cancers in children and young adults. Researchers will look for the highest dose of avutometinib that is safe and cause few or mild side effects.
Somatic mosaicism in cancer associated genes is one potential explanation for discordance in childhood cancer that has not been fully explored to date. This pilot study will focus on twins with central nervous system (CNS) tumors who are identified through the Children's Oncology Group's Project: EveryChild (PEC) registry or volunteer.
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").
<Purpose of the Research> - Primary Establishing an Asian consortium to establish a database of pediatric CNS tumors in the prospective manner The target disease of this research focuses on pediatric tumors, and initially the registration of patients with CNS GCT will begin first. - Secondary Developing clinical protocols for pediatric CNS tumors based in Asia <Duration of Research Participation> Registration period for research subjects: 2022-08-01 - 2027-12-31 Duration of medical records to be utilized: to 2030-12-31 Total projected duration of research: IRB approved to 2032-12-31 Interim assessment of data quality and integrity: 6 Mo after Data collection Evaluation for the Adaptation of Protocols: 1 and 2 years after the initiation of the study Analysis of Quality of Life and other questionnaires: 3 and 5 years Interim Analysis of all data: 5 years (2027) Final analysis of treatment outcome: 2032
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.
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.
