[PMID: 36460199 DOI: 10.1016/j.wneu.2022.11.098] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Revised: 11/21/2022] [Accepted: 11/22/2022] [Indexed: 12/02/2022]
Abstract
BACKGROUND The literature on cerebellar liponeurocytoma (CL) has never been systematically assessed using bibliometric analytic methodologies. We quantitatively analyzed the major trends and scientific output regarding CL, highlighting potential avenues for research. METHODS Elsevier's Scopus database was used to collect all published studies relevant to cerebellar liponeurocytoma from 1978 to 2021. The specific bibliometric parameters were extracted and analyzed with R v4.1.2. RESULTS Our search yielded 108 documents published in 67 sources from 1978 to 2021. The annual growth rate of publications regarding CL has been 7.47% per year since 1978. Journals with the most publications on CL include Clinical Neuropathology and Neurology India (n = 5), followed by Acta Neuropathologica and Journal of Neuro-oncology (n = 4). A total of 529 authors have published on CL and they have been cited 598 times. The 10 most influential authors in the field were determined using their total number of citations and the local H-index. Kleihues P has the highest number of citations (n = 177) with a local H index of 3, followed by Chimelli L with 167 citations and a local H index of 4. Davis DG has 149 citations and a local H index of 3. China had the most single country publications followed by India, Italy, and the USA. France and Austria have the most multiple country publications followed by China, Tunisia, Brazil, United Kingdom, Egypt, and Israel. CONCLUSIONS Our study is the first bibliometric analysis evaluating the present literature and publication trends in CL. Generally, the current literature has a few studies regarding CL relative to other neuro-oncological pathologies. This can be due to the low incidence of the disease and highlights a need for high volume database studies that can offer high quality evidence on the subject.

Surgical management and clinical outcomes of cerebellar liponeurocytomas-a report of seven cases and a pooled analysis of individual patient data. Neurosurg Rev 2022; 45:1747-1757. [PMID: 34982306 DOI: 10.1007/s10143-021-01728-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2021] [Revised: 12/14/2021] [Accepted: 12/27/2021] [Indexed: 10/19/2022]
Abstract
Cerebellar liponeurocytomas (CLPNs) are very rare, with very few studies on this disease. Their treatment protocol also remains unclear. To better understand the disease, we reviewed the clinical features and outcomes, and proposed a treatment protocol based on previously reported cases as well as cases from our institute. The clinical data were obtained from seven patients with pathologically confirmed CLPNs, who underwent surgical treatment at our institute between November 2011 and June 2021. We also reviewed the relevant literature and 75 patients with CLPNs were identified between September 1993 and June 2021. Risk factors for progression-free survival (PFS) were evaluated in the pooled cohort. Our cohort included four males and three females, with a mean age of 43.9 ± 14.5 years (range: 29-64 years). CLPNs were located in the lateral ventricle in three cases and in the cerebellum in four cases. All seven cases achieved gross total resection (GTR) and radiotherapy was administered to two cases. After a mean follow-up of 44.9 ± 44.4 months, all patients remained well, with no recurrence or death. Among the 75 patients reported in the literature, 35 were males and 40 were females, with a mean age of 46.2 ± 13.6 years (range: 6-77 years). Biopsy, GTR, and non-GTR were achieved in one (1.3%), 50 (66.7%), and 24 (32%) patients, respectively. Radiotherapy was administered to 16 cases and chemotherapy was administered to only one case. After a mean follow-up of 47.5 ± 51.5 months, three patients died and tumor recurrence occurred in 17 patients. Multivariate Cox analysis revealed that non-GTR predicted a poor PFS (p = 0.020), and postoperative radiotherapy could not prolong PFS (p = 0.708). Kaplan-Meier analysis also showed that GTR was significantly associated with longer PFS (p = 0.008), and postoperative radiotherapy could not prolong PFS (p = 0.707). PFS rates at 1, 5, 10 years were 92.7%, 78.0%, 23.8% respectively. CLPNs are very rare brain tumors. Although they have favorable clinical prognosis, the recurrence is relatively high. GTR should be the first choice for treatment and close follow-up is necessary. Postoperative radiotherapy could not improve PFS in this study. A larger cohort is needed to verify our findings.

Abstract
Background Cerebellar liponeurocytoma is a rare benign neoplasm of the central nervous system, which arises mainly in adult patients with only 3 cases reported in children. Due to its rarity, the diagnosis and treatment strategies for cerebellar liponeurocytoma remain unclear. The purpose of this study was to explore the epidemiology, clinical features, imaging findings, pathological characteristics, different diagnoses, treatment, and prognosis of cerebellar liponeurocytoma in juveniles. Case Description A 5-year-old boy was admitted to the department of neurosurgery due to a 5-month history of headaches, nausea, vomiting, dizziness, dysphoria, as well as visual blurring associated with the peak of the headache. Magnetic resonance imaging showed a 4.9×5.4×6.2 cm mass located in the fourth ventricle and cerebellar vermis combined with hydrocephalus and periventricular edema. The mass was completely removed, and pathological examination indicated a cerebellar liponeurocytoma of the World Health Organization Grade II classification. Conclusion The present study was the first to report a cerebellar liponeurocytoma with total tumor resection and adjuvant radiotherapy in a pediatric patient. Total tumor resection and postoperative radiotherapy together with close and long-term follow-up seem to be the optimal treatment strategy for juvenile patients. However, the side-effect of radiation needs to be considered.

Abstract
Cerebellar liponeurocytoma (cLNC), categorized as a World Health Organization grade II tumor, is a rare neoplasm characterized by advanced neuronal/neurocytic differentiation and focal lipid accumulation in neuroepithelial tumor cells. However, the expression and genetic profiling of cLNC have been poorly studied. A 44-year-old woman with a three-year history of cerebellar ataxia and numbness in lower extremities underwent radiological examination revealing multiple contrast-enhancing tumors at the floor of the fourth ventricle and in the lower vermis, and spinal dissemination. The high uptake of 11 C-methionine in positron emission tomography (Met-PET) supported the preoperative cLNC diagnosis. Subtotal removal of the tumor around the obex and inferior vermis was performed. Histologically, the tumor was composed of small, uniform cells with round nuclei in a sheet-like fashion. Tumor cells were diffusely reactive for the neuronal markers synaptophysin and neurofilament. Vacuolate cells with a displacement of nuclei suggested the accumulation of lipid, which was further supported by immunohistochemical staining of S-100. These findings confirmed the diagnosis of cLNC. Next-generation sequencing of tumoral DNA detected a splice site mutation in the ATRX gene. Further reports of cLNC cases with detailed expression and genetic profiles are essential for precise diagnosis and clarifying the oncogenic pathway in cLNC.

Abstract
BACKGROUND Liponeurocytoma is an uncommon tumor of the central nervous system. It is very rare for this tumor to originate within the lateral ventricle. In the context of the rarity of this tumor entity, this review article aims to summarize the clinical, radiological, and pathological features of lateral ventricular liponeurocytoma to facilitate its diagnosis and management. METHODS Here, we conduct a systematic literature review using the Pubmed, Scopus, and Cochrane Library database for all cases of lateral ventricular liponeurocytoma. A case illustration complements this review. RESULTS The described cases from 1997 onward include 14 cases that have been published in full papers in the English literature. Six additional cases are reported in short English abstracts in full non-English papers, and one case was described in a central neurocytoma report. There is a definite male predominance of 70% (14 male) and a mean age of 37 years (range 24-62). Heterogenous enhancement and signals in magnetic resonant images (MRI) are the radiological characteristics. In all reported cases, the presence of lipocytes and fat vacuoles is considered the paramount histopathological feature. Total surgical resection was achieved in 80% (12 out of 15) of the cases. Only two cases (including ours) received radiation therapy. Recurrence was seen in two patients during follow-up that was treated by radiation therapy in one and surgery in the other. The proliferation index is mostly below 5% in all cases, with the Ki-67 range between<1% to 10%. CONCLUSIONS Lateral ventricular liponeurocytoma has been treated effectively by surgical resection in a limited number of cases. The decision for radiation therapy is based on a high proliferation index and tumor recurrence.
