[PMID: 36686752 PMCID: PMC9852998 DOI: 10.3389/fonc.2022.1014506] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Accepted: 12/19/2022] [Indexed: 01/07/2023] Open
Abstract
Purpose The study aimed to identify clinical prognostic factors affecting overall survival (OS) in patients with central neurocytoma (CN) and to determine independent prognostic factors in the subgroups of different treatment modalities using a retrospective analysis based on the SEER database from 2003 to 2019. Materials and methods Data regarding patients with CN, including basic clinical characteristics, treatment measures, and prognosis follow-up, were extracted from the SEER database. The prognostic variables for all patients were assessed using log-rank test as well as univariate and multivariate analyses based on the Cox proportional hazards model. The same statistical methods were used for analysis in different subgroups of gross total resection (GTR), subtotal resection (STR), no surgery, radiotherapy (RT), and no RT. Results In total, 413 patients were enrolled in this study. Tumor size, primary site surgery, and RT were independent prognostic factors in all patients with CN. In subgroup analyses, RT was not an independent prognostic factor in patients with GTR. However, sex and race were independent prognostic factors in patients with STR. Additionally, tumor size was an independent prognostic factor in patients who did not undergo surgery. Furthermore, sex and primary site were independent prognostic factors in patients who received RT. Size and primary site surgery were independent prognostic factors in patients without RT. Conclusion In our study, patients with small tumors or GTR or those who did not receive RT showed a better prognosis. GTR was the preferred treatment for CN. RT was not recommended for patients after GTR. Men and African American showed certain advantages after STR surgery. Tumors with a size of >4 cm were recommended for active treatment. In the RT subgroup, patients with tumors outside the ventricle or women had a poorer prognosis than those with tumors within the ventricle or men, respectively. These findings will help clinicians and patients understand the treatment and prognosis of CN visually and intuitively.

Abstract
Central neurocytomas (CNs) are rare benign tumors located in the central nervous system with a good prognosis. These tumors are predominantly located in the lateral ventricle near the foramen of Monro or in the third ventricle. Similar tumors that are located outside the ventricle are also called extraventricular neurocytomas, and have an even lower morbidity. Until now, several tumors have been identified in the thalamus, cerebellum, pons, medulla oblongata and spinal cord. In total, 24 cases of neurocytomas located in the spinal cord have been reported in English journals. The present study reported a patient with an intramedullary central neurocytoma of the thoracic spinal cord, diagnosed from clinical features, imaging findings, pathology and immunohistochemistry. The present case report also outlined the prognosis of the patient and reviewed the literature currently available on CNs located in the spinal cord.

Abstract
Central neurocytoma (CN) is a rare, benign brain tumor often located in the lateral ventricles. CN may cause obstructive hydrocephalus and manifest as signs of increased intracranial pressure. The goal of treatment for CN is a gross total resection (GTR), which often yields excellent prognosis with a very high rate of tumor control and survival. Adjuvant radiosurgery and radiotherapy may be considered to improve tumor control when GTR cannot be achieved. Chemotherapy is also not considered a primary treatment, but has been used as a salvage therapy. The radiological features of CN are indistinguishable from those of other brain tumors; therefore, many histological markers, such as synaptophysin, can be very useful for diagnosing CNs. Furthermore, the MIB-1 Labeling Index seems to be correlated with the prognosis of CN. We also discuss oncogenes associated with these elusive tumors. Further studies may improve our ability to accurately diagnose CNs and to design the optimal treatment regimens for patients with CNs.

Abstract
Central neurocytoma is a relatively rare tumor of the central nervous system. Young adults are most commonly affected, with a similar incidence in males and females. The tumor is predominantly occurs in the ventricular system of the brain. The tumor is benign and exhibits a good response to surgical resection and radiation therapy. The typical central neurocytoma occurs in the supratentorial ventricular system in young adults. Extraventricular neurocytomas are rare in the spinal cord. In the present study, two cases of craniocervical neurocytomas and the clinical presentation, magnetic resonance imaging observations, pathological features and two-year follow-up results are reported. The first case presents a 26 year old male with an intramedullary mass extending from the medualla oblongata to the T4 segement of the spine. The second case presents the case of a 48 year old female with an intramedullary mass extending from the oblongata to the T2 segement of the spine. The two patients underwent subtotal resection of the masses and post-operative radiotherapy was administered for three months. Post-operative magentic resoance imaging revealed no tumor recurrence in the two cases, two years after resection. The relevant literature is also discussed.

Abstract
OBJECTIVE Visual and auditory hallucinations in relation to a cerebellar tumor are rarely reported in children. Primary origin of extraventricular neurocytoma (EVN) in the cerebellum is very rare. CLINICAL PRESENTATION We report on a case of a cerebellar EVN in a 13-year-old girl with the initial symptoms of psychiatric manifestations for more than 2 months. Magnetic resonance imaging of the brain revealed a patchy enhanced tumor in the paramedian left cerebellar region. No obstructive hydrocephalus was noted. INTERVENTION Total surgical removal of the tumor was performed. The tumor was initially diagnosed as an oligodendroglioma. After special immunohistochemical studies, the final definitive diagnosis was an EVN without isocitrate dehydrogenase mutation. CONCLUSION EVNs located in the cerebellum are extremely rare. We discuss the clinical symptoms and histological-immunohistochemical features of this rare tumor in that rare location.

Abstract
Neurocytomas are typically intraventricular in location, and extraventricular neurocytomas are uncommon. The authors report the unique case of a 15-year-old girl who was found to have a low-grade neurocytoma infiltrating the brainstem and cerebellum and spreading along the CSF pathways to the lateral and third ventricles. The patient underwent endoscopic third ventriculostomy to treat associated hydrocephalus, and biopsy specimens from intraventricular tumor nodules were obtained. Because of the low-grade pathology, the fact that the lesion was not amenable to resection, and the extensive radiation field required for radiation therapy, she has been treated conservatively with close follow-up. Over the course of almost 4 years since diagnosis, no additional treatment has been required. Neurocytoma with widespread infiltration of the brainstem and cerebellum has not been previously reported.

Abstract
Central neurocytoma was originally described as a rare benign neuronal tumor. However, progression and local recurrences after surgery are well recognized. Stereotactic radiosurgery is another option for treatment of CN. In order to evaluate the efficacy of SRS, we performed a quantitative systematic review of the available data on SRS for CN. To identify eligible studies, systematic searches for all CNs treated with SRS were conducted in major scientific publication databases. English studies published prior to May 2011 were reviewed and summarized with reference to the inclusion and exclusion criteria. Tumor local control was analyzed. Heterogeneity and publication bias were assessed, and the summary control rate and 95%confidence interval (CI) were calculated from the raw data.Of 35 eligible studies, five with a total of 64 CNs were included in this quantitative analysis. Four studies reported a mean or median follow-up time of[60 months. The test of heterogeneity was non-significant among the included studies. Publication bias was observed as indicated by an asymmetric funnel plot. There was non-significance in Begg’s test and Egger’s test. The estimated cumulative rate of neuro-imaging tumor control was 91.1% (95%CI = 80.2–96.3%) at a mean follow-up of 59.3 months(range 6–140 months). The P-value was\0.0001 under a random-effect model. Sensitivity analysis showed a similar summary control rates (89.5–93.7%). Based on the summary local control rate of SRS for CN found in this quantitative analysis, we suggest that single session SRS is an effective and safe alternative therapy for recurrent or residual CN. However, the results of our analysis are limited by the predominance of case series studies due to scarcity of published research. Further randomized trials of CN patients via multicenter consortia should be considered for supplementing the weak points in our quantitative analysis.
