Abstract
INTRODUCTION Central Neurocytoma (CN) is a rare, WHO grade 2 brain tumor that predominantly affects young adults. Gross total resection (GTR) is often curative for CNs, but the optimal treatment paradigm including incorporation of RT, following subtotal resection (STR) and for scarcer pediatric cases has yet to be established. METHODS Patients between 2001 and 2021 with a pathologic diagnosis of CN were reviewed. Demographic, treatment, and tumor characteristics were recorded. Recurrence free survival (RFS) and overall survival (OS) were calculated according to the Kaplan Meier-method. Post-RT tumor volumetric regression analysis was performed. RESULTS Seventeen adults (≥ 18 years old) and 5 children (< 18 years old) met the criteria for data analysis (n = 22). With a median follow-up of 6.9 years, there was no tumor-related mortality. Patients who received STR and/or had atypical tumors (using a cut-off of Ki-67 > 4%) experienced decreased RFS compared to those who received GTR and/or were without atypical tumors. RFS at 5 years for typical CNs was 67% compared to 22% for atypical CNs. Every pediatric tumor was atypical and 3/5 recurred within 5 years. Salvage RT following tumor recurrence led to no further recurrences within the timeframe of continued follow-up; volumetric analysis for 3 recurrent tumors revealed an approximately 80% reduction in tumor size. CONCLUSION We provide encouraging evidence that CNs treated with GTR or with RT after tumor recurrence demonstrate good long-term tumor control.

Abstract
We present a patient with an intraventricular hemorrhage. Imaging identified a left atrial intraventricular mass and a vague adjacent second periventricular cystic lesion. A guided trans-sulcal approach via a left parietal craniotomy resulted in a gross total resection of both lesions. These represented two distinct lesions, the periventricular cystic lesion was an extraventricular neurocytoma (EVN) and a World Health Organization grade 1 choroid plexus papilloma (CPP). The neurocytoma required methylation studies for confirmatory diagnosis. The patient had an uneventful recovery with a normal neurological exam at 12-weeks. This documents the occurrence of two distinct central nervous system tumors, a CPP and an EVN presenting with an intraventricular hemorrhage.

Abstract
PURPOSE Pediatric central neurocytomas (PCNs) is an extremely rare entity, and very few reports have exclusively focused on the clinicopathologic features and surgical outcomes of PCNs. METHODS This study was undertaken to elucidate the clinical and pathological characteristics and long-term surgical outcomes of PCNs. RESULTS Fourteen consecutive patients with pathologically verified PCNs were identified, including 9 girls and 5 boys, with a mean age of 15.2 ± 3.9 years (range 3-18 years). Children tended to present with symptoms of increased intracranial pressure (ICP) (p = 0.003), an acute clinical course (p = 0.044), and a shorter duration of symptoms (p = 0.019) than their adult counterparts. Surgery was performed under the guidance of a neuronavigation system and intraoperative ultrasound; gross total resection (GTR) was achieved in 12 patients (85.7%), and subtotal resection (STR) was achieved in two patients (14.3%). One child received adjuvant radiotherapy (RT) owing to the atypical features of the lesion. During a mean follow-up of 90.2 ± 37.0 months (range 42-156 months), one patient (7.1%) with atypical features experienced lesion relapse 2 years after surgery and received RT, and the symptoms of all children were relieved. CONCLUSION Surgery can benefit children with CNs and ensure relatively long-term progression-free survival. RT can be administered to patients with residual or relapsed lesions.

Cancers (Basel) 2022; 14:cancers14041085. [PMID: 35205834 PMCID: PMC8869944 DOI: 10.3390/cancers14041085] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 02/03/2022] [Accepted: 02/09/2022] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND CyberKnife-based robotic radiosurgery (RRS) is a widely used treatment modality for various benign and malignant tumors of the central nervous system (CNS) in adults due to its high precision, favorable safety profile, and efficacy. Although RRS is emerging in pediatric neuro-oncology, scientific evidence for treatment indications, treatment parameters, and patient outcomes is scarce. This systematic review summarizes the current experience and evidence for RRS and robotic stereotactic radiotherapy (RSRT) in pediatric neuro-oncology. METHODS We performed a systematic review based on the databases Ovid Medline, Embase, Cochrane Library, and PubMed to identify studies and published articles reporting on RRS and RSRT treatments in pediatric neuro-oncology. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were applied herein. Articles were included if they described the application of RRS and RSRT in pediatric neuro-oncological patients. The quality of the articles was assessed based on their evidence level and their risk for bias using the original as well as an adapted version of the Newcastle Ottawa Quality Assessment Scale (NOS). Only articles published until 1 August 2021, were included. RESULTS A total of 23 articles were included after final review and removal of duplicates. Articles reported on a broad variety of CNS entities with various treatment indications. A majority of publications lacked substantial sample sizes and a prospective study design. Several reports included adult patients, thereby limiting the possibility of data extraction and analysis of pediatric patients. RRS and RSRT were mostly used in the setting of adjuvant, palliative, and salvage treatments with decent local control rates and acceptable short-to-intermediate-term toxicity. However, follow-up durations were limited. The evidence level was IV for all studies; the NOS score ranged between four and six, while the overall risk of bias was moderate to low. CONCLUSION Publications on RRS and RSRT and their application in pediatric neuro-oncology are rare and lack high-quality evidence with respect to entity-related treatment standards and long-term outcomes. The limited data suggest that RRS and RSRT could be efficient treatment modalities, especially for children who are unsuitable for surgical interventions, suffer from tumor recurrences, or require palliative treatments. Nevertheless, the potential short-term and long-term adverse events must be kept in mind when choosing such a treatment. Prospective studies are necessary to determine the actual utility of RRS and RSRT in pediatric neuro-oncology.

Abstract
Neuronal and mixed glioneuronal tumors represent a group of neoplasms with varying degrees of neural and glial elements. Their age of presentation varies, but they are most commonly seen in children and young adults. With the exception of anaplastic ganglioglioma and other atypical variants, most lesions are low grade; however, they can have significant morbidity because of seizures, mass effect, or difficult to treat hydrocephalus. Although many tumors show overlapping clinical and imaging features, some have relatively distinctive imaging characteristics that may aid in narrowing the differential diagnosis. In this review, we discuss relevant clinical and pathologic characteristics of these tumors and provide an overview of conventional and advanced imaging features that provide clues as to the diagnosis.

Abstract
Extraventricular neurocytoma (EVN) is an extremely rare tumor of neuroglial origin with a tendency toward ganglionic or glial differentiation. In the 2016 World Health Organization Classification, EVN was classified as a grade II tumor and described as a neoplasm with good outcome. However, the presence of cellular atypia is an important unfavorable prognostic factor. Here, we describe the first case of a patient with a congenital EVN localized in the brainstem. After a sub-total resection, his disease rapidly progressed despite several chemotherapies, including molecular targeting approaches. He died 13 months after diagnosis. In conclusion, we report an atypical case of EVN presenting an extremely aggressive behavior, despite the absence of cellular atypia. The brainstem origin and the age of the patient may have represented two important prognostic factors for our patient.

Abstract
Les neurocytomes centraux sont définis comme étant des néoplasmes composés de cellules rondes, uniformes, ayant un profil immunophénotypique neuronal et un index de prolifération bas. Elles représentent 0,5% des tumeurs intracrâniennes. Elles sont habituellement situées à proximité du foramen de Monro et peuvent être à l’origine d’une hydrocéphalie obstructive. Nous rapportons 12 observations de neurocytomes centraux colligés au laboratoire d’anatomie pathologique du CHU Mohammed VI de Marrakech entre janvier 2006 et juin 2015. Le but de ce travail est de rapporter et décrire les aspects radio-pathologiques de ce type histologique rare. Le sex-ratio homme/femme était de 1,4. L’âge moyen au diagnostic était de 22,3 ans. La symptomatologie révélatrice était dominée par l’hypertension intracrânienne chez tous nos patients, associée à une baisse de l’acuité visuelle et une diplopie. Notre matériel d’étude a concerné une biopsie simple dans un cas, une exérèse subtotale dans sept cas et une exérèse totale dans quatre cas. L’étude histopathologique a montré une prolifération tumorale d’architecture endocrine. Les cellules tumorales sont uniformes de petite taille le plus souvent. L’index mitotique était bas. Cette prolifération tumorale s’accompagnait d’un fond fibrillaire et d’un réseau vasculaire développé de type arborescent. L’étude immunohistochimique était identique chez tout les patients. Elle a montré une positivité des cellules tumorales à l’anticorps anti synaptophysine, à chromogranine et NSE. Chez tous nos patients la corrélation radiopathologique était en faveur d’un neurocytome central (Grade II – OMS 2016). A travers cette série, nous rapportons les particularités anatomo-cliniques, radiologiques et évolutives de ces tumeurs rares.

Abstract
Central neurocytomas are well-differentiated tumors of neuronal origin. These are relatively uncommon in the pediatric population. Anaplastic features reflected by brisk mitotic activity, microvascular proliferation, necrosis, and MIB-1 labeling index >2% or 3% have been proposed to indicate aggressive behavior. Because of its rarity, there is paucity of data regarding the histologic spectrum and outcome of central neurocytomas in children. With this short series, we describe our observations of the clinicopathologic characteristics and outcome of this tumor in children over a 5-year period.

Abstract
We report a childhood case of thalamic atypical extraventricular neurocytoma that progressed to highly anaplastic ganglioglioma after 8 years of dormancy after subtotal resection and chemotherapy. The neurocytoma displayed immunoreactivity only for synaptophysin, β-catenin, S100, and CD56. The ganglioglioma acquired strong immunoreactivity for chromogranin, glial fibrillary acidic protein, neuron-specific enolase, and p53 and showed a very high proliferation rate approaching 50% in some areas. Tumor transformation was associated with overexpression of components of the sonic hedgehog and Wnt developmental signaling pathways, which are known to regulate tumor-initiating cells in malignant brain neoplasms.
