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.
Radiotherapy involves the use of high-energy X-rays, which can be used to stop the growth of tumor cells. Radiotherapy constitutes an essential avenue in the treatment of brain tumors. The modern techniques of radiotherapy involve radiation planning techniques guided by computer algorithms aimed to deliver high doses of radiation to the areas of brain with tumors and limit the doses to surrounding normal structures. Artificial intelligence uses advanced analytical processes aided by computational analysis, which can be undertaken on the medical images, and radiation planning process. We plan to use artificial intelligence techniques to automatically delineate areas of the brain with tumor and other normal structures as identified from images. Also, we will use artificial intelligence on the radiation dose images and other images done for radiation treatment to classify tumors with good or bad prognoses, identify patients developing radiation complications, and detect responses after treatment.
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.
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.
