[Ab] Abstract:RATIONALE: Cerebellar liponeurocytoma is a rare tumor of the central nervous system (CNS) characterized by low proliferation but high likelihood of recurrence. Because of its rarity and the paucity of systematic follow-up, the biological behaviors and clinical features of this tumor are still poorly understood. We herein reported a case of cerebellar liponeurocytoma originating in the cerebral hemisphere. PATIENT CONCERNS: A 11-year-old male with intermittent headache, nausea, and vomiting. The first computed tomography revealed a large mass in the right cerebral hemisphere. He was transferred to our institution for neurosurgical treatment. DIAGNOSIS: Magnetic resonance imaging showed a large cystic-solid mass in the right frontal lobe with obvious contrast enhancement. Histopathological examinations showed sheets of isomorphic small neoplastic cells with clear cytoplasm and focal lipomatous differentiation. On immunohistochemistry, tumor cells were positive for synaptophysin, microtubule-associated protein 2, and neuronal nuclei antigen. INTERVENTIONS: The patient was performed a right fronto-parietal craniotomy, and gross total resection of the tumor was achieved without adjuvant therapy. OUTCOMES: No clinical or neuroradiological evidence of recurrence or residual of the tumor was found 6 years and 2 months after initial surgery. LESSONS: Cerebellar liponeurocytoma developing in supratentorial cerebral hemisphere was first reported in the present study. The radiological and histopathological features may be useful in differentiating this rare tumor from other tumors at similar locations. A change in the nomenclature of cerebellar liponeurocytomas should be considered in future World Health Organization (WHO) classifications.

[Ab] Abstract:OBJECTIVE: Cortical ependymomas (CEs), supratentorial ependymomas that selectively involve the cerebral cortex, are relatively rare neoplasms that have not been extensively described. The purpose of our study was to identify the clinical features, radiologic characteristics, and treatment of a series of such tumors. METHODS: Thirteen patients with CEs from our hospital were included in this study. Epidemiologic characteristics, clinical features, imaging findings, treatment methods, and clinical outcomes were reviewed retrospectively. RESULTS: The patients consisted of 7 men and 6 women with mean age of 31.1 ± 23.2 years (range, 4-74 years). The most common clinical manifestation was seizure (n = 11; 85%), followed by headache (n = 2; 15%). None of the tumors were incidentally detected. Eight CEs were located in the right hemisphere and 5 in the left side. The 2 most common tumor locations were the frontal (n = 5; 38%) and parietal lobe (n = 5; 38%). All patients underwent surgical resection. Gross total resection was achieved in 12 patients (92%), and subtotal resection was performed in 1 patient (8%). Ten of the 11 patients who presented with seizure are seizure-free after surgery (91% seizure-free rate). According to the World Health Organization classification system, 9 tumors (69%) were Grade II (ependymoma) and 4 (31%) were Grade III (anaplastic ependymoma). The mean follow-up was 52 months (range, 20-88 months). No recurrence was observed in patients with Grade II CEs. Of 4 patients with Grade III CEs, 2 (50%) suffered from tumor recurrence after initial treatment. CONCLUSIONS: CEs are a rare subset of supratentorial ependymomas that selectively involve the cerebral cortex. Most CEs are low grade and present with seizures. Anaplastic CEs show a greater recurrence rate and a relatively poor prognosis. Gross total resection with or without adjuvant radiotherapy is currently the optimal treatment for CEs. CEs seem to have a more favorable prognosis than other supratentorial ependymomas.

[Ab] Abstract:Pediatric embryonal brain tumor patients treated with craniospinal irradiation (CSI) are at risk for adverse effects, with greater severity in younger patients. Here we compare outcomes of CSI vs. high-dose chemotherapy (HD), stem cell transplant (SCT) and delayed CSI in newly diagnosed patients. Two hundred one consecutive patients treated for medulloblastoma (72 %), supratentorial primitive neuroectodermal tumor (sPNET; 18 %) or pineoblastoma (10 %) at two institutions between 1988 and 2014 were retrospectively identified. Progression free survival (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method and compared by log-rank tests. Adjuvant CSI regimens were used for 56 % of patients (upfront-CSI), and HD/SCT regimens were used in 32 % of patients. HD/SCT patients were significantly younger than those receiving upfront-CSI (2.9 vs. 7.8 years; P < 0.0001). There were no differences in metastases, extent of resection, or CSI dose between upfront-CSI and HD/SCT patients, but median follow-up was shorter in the HD/SCT group (6.2 vs. 3.9 years; P = 0.007). There were no significant outcome differences between upfront-CSI and HD/SCT patients who received CSI as a prophylaxis or following relapse (OS 66 % vs. 61 %, P = 0.13; PFS 67 % vs. 62 %, P = 0.12). Outcomes were equivalent when restricting analyses to HD/SCT patients who received prophylactic CSI prior to relapse (OS 66 % vs. 65 %, P = 0.5; PFS 67 % vs. 74 %, P = 0.8). At last follow-up, 48 % of HD/SCT patients had received neither definitive nor salvage radiotherapy. In this retrospective cohort, outcomes with adjuvant HD/SCT followed by delayed CSI are comparable to upfront-CSI for carefully surveyed pediatric embryonal brain tumor patients. Future prospective studies are required to validate this finding, and also to assess the impact of delayed CSI on neurocognitive outcomes.

[Ab] Abstract:Ependymomas (EPs) are tumors of the brain and spinal cord constituting ∼10% of the childhood central nervous system neoplasms and about 30% in children aged <3 years. Their anatomic distribution varies according to the age, with those arising in the supratentorial (ST) compartment, spinal cord being more common in older children and adults, and those at the infratentorial location are more common and occurring more frequently in infants and children. Recently, molecular classification of EP subgroups has been proposed and a supratentorial ependymoma subgroup characterized by RELA-fusion genes (ST-EP-RELA) has been established. It would be useful to define a standardized, robust method for the diagnosis of these relevant fusion genes. We used real-time polymerase chain reaction, conventional real-time polymerase chain reaction, and Sanger sequencing to characterize RELA fusion status in formalin-fixed paraffin-embedded samples from 42 ST-EPs (12 adults and 30 pediatric). We tested p65/RELA and L1CAM protein immunohistochemistry for their ability to predict RELA-fusion status. We reviewed clinical data to assess significant associations in this anatomic subgroup. Of the 42 patients, we identified RELA-fusion genes in 17 cases. L1CAM immunostaining displayed 94% sensitivity, 76% specificity, 73% positive predictive value (PPV), 95% negative predictive value (NPV). The p65/RELA immunostaining displayed 100% sensitivity, 92% specificity, 89.5% PPV, 100% NPV. Concordant double immunostaining improves PPV to 92.5% and maintains 100% NPV. Immunohistochemistry using both p65/RELA and L1CAM antibodies is valuable for ST-EP-RELA diagnosis: the negativity with both antibodies consistently predicts the absence of RELA fusions, whereas verification of fusion transcripts by molecular analyses is warranted only in single-positive or double-positive staining cases.

[Ab] Abstract:INTRODUCTION: Intracranial metastases of gastro intestinal tumors are very rare. To the best of our knowledge only few cases were reported on the literature. CASE DESCRIPTION: We describe the case of 66-year-old male that presented with headache and vomiting. Physical examination found a kinetic cerebellar syndrome. Brain CT scan and MRI showed a right cerebellar tumor. Sub-occipital craniotomy was performed and the tumor was completely resected. Surgical outcomes were marked by the occurrence of an abdominal pain two days after brain surgery. Peritonitis was diagnosed and the patient underwent surgery. Per-operatively, a hemorrhagic tumor perforating the intestines was found and resected. Pathologic examination of the cerebral tumor's resection piece and the intestinal resection piece concluded to a metastasis of a stromal gastro-intestinal tumor. DISCUSSION: Gastro-intestinal stromal tumors are frequent neoplasms, but intracranial metastases of these neoplasms are extremely rare. Abdominal symptomatology frequently reveals the pathology. However, extra digestive symptoms may in rare cases disclose intestinal tumors. Intracranial metastases of gastro-intestinal stromal tumors are generally solitary mainly supratentorial. Infratentorial metastases are very uncommon. Management of gastro-intestinal stromal tumors is based on surgical removal of the tumor. Adjuvant treatment consisting on chemotherapy and radiotherapy is subject of debate. CONCLUSIONS: Gastro-intestinal stromal tumors are frequent neoplasms with a high metastasizing potential on liver and peritoneum. Brain metastases are extremely rare and the prognosis is worse when they are present. Surgery remains the main treatment for the primitive and the secondary lesions.

[Ab] Abstract:Ependymoma is the third most common pediatric primary brain tumor. Ependymomas are categorized according to their locations and genetic abnormalities, and these two parameters are important prognostic factors for patient outcome. For supratentorial (ST) ependymomas, RELA fusion-positive ependymomas show a more aggressive behavior than YAP1 fusion-positive ependymomas. Extracranial metastases of intra-axial neuroepithelial tumors are extremely rare. In this paper, we report a case of aggressive anaplastic ependymoma arising in the right frontoparietal lobe, which had genetically 1q25 gain, CDKN2A homozygous deletion, and L1CAM overexpression. The patient was a 10-year-old boy who underwent four times of tumor removal and seven times of gamma knife surgery. Metastatic loci were scalp and temporalis muscle overlying primary operation site, lung, liver, buttock, bone, and mediastinal lymph nodes. He had the malignancy for 10 years and died. This tumor is a representative case of RELA fusion-positive ST ependymoma, showing aggressive behavior.

[Ab] Abstract:OBJECTIVE The majority of neurosurgeons administer antiepileptic drugs (AEDs) prophylactically for supratentorial tumor resection without clear evidence to support this practice. The putative benefit of perioperative seizure prophylaxis must be weighed against the risks of adverse effects and drug interactions in patients without a history of seizures. Consequently, the authors conducted a systematic review of prospective randomized controlled trials (RCTs) that have evaluated the efficacy of perioperative seizure prophylaxis among patients without a history of seizures. METHODS Five databases (PubMed/MEDLINE, Cochrane Central Register of Controlled Trials, CINAHL/Academic Search Complete, Web of Science, and ScienceDirect) were searched for RCTs published before May 2017 and investigating perioperative seizure prophylaxis in brain tumor resection. Of the 496 unique research articles identified, 4 were selected for inclusion in this review. RESULTS This systematic review revealed a weighted average seizure rate of 10.65% for the control groups. There was no significant difference in seizure rates among the groups that received seizure prophylaxis and those that did not. Further, this expected incidence of new-onset postoperative seizures would require a total of 1258 patients to enroll in a RCT, as determined by a Farrington-Manning noninferiority test performed at the 0.05 level using a noninferiority difference of 5%. CONCLUSIONS According to a systematic review of major RCTs, the administration of prophylactic AEDs after brain tumor resection shows no significant reduction in the incidence of seizures compared with that in controls. A large multicenter randomized clinical trial would be required to assess whether perioperative seizure prophylaxis provides benefit for patients undergoing brain tumor resection.

[Ab] Abstract:BACKGROUND: Supratentorial hemangioblastoma is an uncommon lesion with few data available. Resemblance to other tumours represents a struggle concerning pre-operative diagnosis and management. OBJECTIVES: The aim of this study was to review the current literature, integrating two new cases with uncommon features. METHODS: A search of English language peer-reviewed articles in PubMed®, Cochrane Library®, Google Scholar® and summary of the current knowledge. RESULTS: A total of 162 cases, with no predominance between von Hippel-Lindau disease and wild-type sporadic lesions. The frontal lobe is the most common topography, followed by the pituitary stalk, with image resemblance to a glioma or a metastasis. From these, 20 cases revealed dural attachment, mimicking a meningioma. Symptoms are due to mass effect or epilepsy, with low haemorrhagic risk. Clinical outcome on supratentorial hemangioblastoma depends on resection extension, with no recognised complementary treatment. Post-operative follow-up is essential, even in wild-type, sporadic cases, concerning recent reports of tumour dissemination. CONCLUSIONS: This review compiles the main characteristics of supratentorial hemangioblastoma, that despite its rarity, should be a concern on differential diagnosis, treatment planning and expected prognosis.

[Ab] Abstract:OPINION STATEMENT: Ependymomas are a subgroup of ependymal glia-derived neoplasms that affect children as well as adults. Arising within any CNS compartment, symptoms at presentation can range from acute onset due to increased intracranial pressure to insidious myelopathy. The overall survival (OS) outcomes in adult patients across the subgroups is heterogeneous with subependymoma having an excellent prognosis often even in the absence of any treatment, whereas supratentorial ependymomas tend to be higher grade in nature and may have an OS of 5 years despite gross total resection and adjuvant radiation. The rarity of ependymal tumors, together still only representing 1.8% of all primary CNS tumors, has been a long-standing challenge in defining optimal treatment guidelines via prospective randomized trials. Retrospective studies have supported maximal safe resection, ideally gross total resection, as the optimal treatment with adjuvant radiation therapy proffering additional tumor control. The evidence for efficacy of chemotherapy and targeted agents in adult ependymomas is minimal. Recent investigations of the molecular, genetic, and DNA methylation profiles of ependymal tumors across all age groups and CNS compartments have identified distinct oncogenic gene products as well as nine molecular subgroups correlating with similar outcomes. The 2016 World Health Organization of Tumors of the Central Nervous System update addresses some of these findings, although their clinical significance has not yet been fully validated. There are inconsistent survival outcomes in retrospective studies for ependymomas graded as II versus III, bringing into question the validity of histologic grading which is subject to high interobserver variability in part due to inconsistent application of mitotic count parameters.

[Ab] Abstract:Objective We aimed to characterise the magnetic resonance imaging (MRI) features of a case series of primary gliosarcoma, with the inclusion of diffusion-weighted imaging and perfusion imaging with dynamic susceptibility contrast MRI. Materials and methods We conducted a retrospective study of cases of primary gliosarcoma from the Pathology Department database from January 2006 to December 2014. Clinical and demographic data were obtained. Two neuroradiologists, blinded to diagnosis, assessed tumour location, signal intensity in T1 and T2-weighted images, pattern of enhancement, diffusion-weighted imaging and dynamic susceptibility contrast MRI studies on preoperative MRI. Results Seventeen patients with primary gliosarcomas had preoperative MRI study: seven men and 10 women, with a mean age of 59 years (range 27-74). All lesions were well demarcated, supratentorial and solitary (frontal n = 5, temporal n = 4, parietal n = 3); 13 tumours abutted the dural surface (8/13 with dural enhancement); T1 and T2-weighted imaging patterns were heterogeneous and the majority of lesions (12/17) showed a rim-like enhancement pattern with focal nodularities/irregular thickness. Restricted diffusion (mean apparent diffusion coefficient values 0.64 × 10 mm /s) in the more solid/thick components was present in eight out of 11 patients with diffusion-weighted imaging study. Dynamic susceptibility contrast MRI study ( n = 8) consistently showed hyperperfusion in non-necrotic/cystic components on relative cerebral volume maps. Conclusions The main distinguishing features of primary gliosarcoma are supratentorial and peripheral location, well-defined boundaries and a rim-like pattern of enhancement with an irregular thick wall. Diffusion-weighted imaging and relative cerebral volume map analysis paralleled primary gliosarcoma with high-grade gliomas, thus proving helpful in differential diagnosis.
