Gliomas with histone H3 lysine27-to-methionine mutations (H3K27M-glioma) arise primarily in the midline of central nervous system young children, suggesting a cooperation between genetics and cellular context tumorigenesis. Although H3K27M-glioma are well characterized, their architecture remains uncharted. We performed single-cell RNA sequencing 3321 cells from six primary matched models. found that contain resemble oligodendrocyte precursor (OPC-like), whereas more differentiated malignant...
Abstract Background Pediatric low-grade glioma (pLGG) is essentially a single pathway disease, with most tumors driven by genomic alterations affecting the mitogen-activated protein kinase/ERK (MAPK) pathway, predominantly KIAA1549::BRAF fusions and BRAF V600E mutations. This makes pLGG an ideal candidate for MAPK pathway-targeted treatments. The type I inhibitor, dabrafenib, in combination MEK trametinib, has been approved United States Food Drug Administration systemic treatment of...
Medulloblastoma (MB) is one of the most prevalent forms malignant brain cancer observed within pediatric patients and particularly difficult to diagnose treat due anatomical localization tumors near brainstem. Currently, there are four molecular classifications MBL: WNT, SHH, Group 3, 4 tumor subgroups. Wingless-type (WNT) mutant least common, often caused by mutations in CTNNB1 gene that plays a crucial role wingless cell signaling pathway, yet associates with best prognosis as compared all...
Abstract Background Median survival time of recurrent embryonal brain tumors is short regardless salvage chemotherapy used. An evolving alternative approach to conventional target neovascularization by interfering with tumor angiogenesis at various levels. Procedure From November 2006 December 2010, 16 patients (median age: 9 years) (9 first, 7 multiple) were treated an antiangiogenic multidrug combination regimen (bevacizumab, thalidomide, celecoxib, fenofibrate, etoposide, and...
Abstract Atypical teratoid rhabdoid tumors ( ATRT s) are recently defined highly aggressive embryonal central nervous system with a poor prognosis and no definitive guidelines for treatment. We report on the importance of an initial correct diagnosis disease‐specific therapy outcome in 22 consecutive patients propose new treatment strategy. From 1992 to 2012, nine initially diagnosed correctly as (cohort A, median age 24 months) were treated according intensive multimodal regimen MUV ‐ )...
Purpose Bevacizumab (BEV) is approved in more than 60 countries for use adults with recurrent glioblastoma. We evaluated the addition of BEV to radiotherapy plus temozolomide (RT+TMZ) pediatric patients newly diagnosed high-grade glioma (HGG). Methods The randomized, parallel group, multicenter, open-label HERBY trial ( ClinicalTrials.gov identifier: NCT01390948) enrolled age ≥ 3 years ≤ 18 localized, centrally neuropathology-confirmed, nonbrainstem HGG. Eligible were randomly assigned...
PurposeNeurofibromatosis type 1 (NF1) is characterized by a highly variable clinical presentation, but almost all NF1-affected adults present with cutaneous and/or subcutaneous neurofibromas. Exceptions are individuals heterozygous for the NF1 in-frame deletion, c.2970_2972del (p.Met992del), associated mild phenotype without any externally visible tumors.MethodsA total of 135 from 103 unrelated families, carrying constitutional p.Met992del pathogenic variant and clinically assessed using...
Diffuse gliomas with K27M histone mutations (H3K27M glioma) are generally characterized by a fatal prognosis, particularly affecting the pediatric population. Based on molecular heterogeneity observed in this tumor type, personalized treatment is considered to substantially improve therapeutic options. Therefore, clinical evidence for therapy, guided comprehensive profiling, urgently required. In study, we analyzed feasibility and outcomes cohort of 12 H3K27M glioma cases treated at two...
Alterations of the fibroblast growth factor (FGF) signalling pathway are increasingly recognized as frequent oncogenic drivers paediatric brain tumours. We report on three patients treated with selective FGFR1-4 inhibitor erdafitinib. Two were diagnosed a posterior fossa ependymoma group A (PFA EPN) and one low-grade glioma (LGG), harbouring FGFR3/FGFR1 overexpression an FGFR1 internal tandem duplication (ITD), respectively. While both EPN did not respond to erdafitinib treatment,...
The Response Evaluation in Neurofibromatosis and Schwannomatosis (REiNS) International Collaboration Whole-Body MRI (WB-MRI) Working Group reviewed the existing literature on WB-MRI, an emerging technology for assessing disease patients with neurofibromatosis type 1 (NF1), 2 (NF2), schwannomatosis (SWN), to recommend optimal image acquisition analysis methods enable WB-MRI as endpoint NF clinical trials.A systematic process was used review all published data about syndromes assess diagnostic...
Low grade gliomas (LGGs) constitute the largest, yet clinically and (molecular-) histologically heterogeneous group of pediatric brain tumors WHO grades I II occurring throughout all age groups at central nervous system (CNS) sites. The are characterized by a slow growth rate may show periods arrest. Around 40% LGG patients can be cured complete neurosurgical resection followed close observation. In case relapse, second often is possible. Following incomplete observation recommended, as long...
Medulloblastoma (MB) recurrence is usually incurable despite intensive therapy including high-dose chemotherapy. An evolving alternative approach to conventional chemotherapy aims at interfering with tumor angiogenesis different levels. We report on a novel combinatorial metronomic antiangiogenic approach.
