Abstract
Ependymoma is the third most common brain tumor in children. Extracranial metastases of ependymomas are uncommon. A 21-month-old Japanese boy was diagnosed to be brain dead due to a posterior fossa (PF) brain tumor. Surgical resection of the tumor was not performed. Twenty-seven months later, he developed a truncal subcutaneous tumor, which was pathologically diagnosed as PF ependymoma group A. We observed the intracranial recurrence of the brain tumor, an invasion to the left orbit, and a neoplasm in his liver before he died. This case suggests that PF ependymoma group A can metastasize extracranially to various organs.

Abstract
Ependymoma is the third most common pediatric primary brain tumor, with its most aggressive subtype being posterior fossa group A (PFA). Extraneural metastasis of pediatric PFA ependymoma is rare. Herein, we present a case of a 9-year-old girl with PFA ependymoma characterized by a lack of trimethylation of histone H3 at lysine 27 and elevated chromosome X open reading frame 67 expression. Despite multiple surgeries and radiotherapies, the patient had a rapid recurrence and developed osseous and pulmonary metastases, which may be attributed to the homozygous deletion of cyclin-dependent kinase (CDK) inhibitor 2A/B and CDK12 mutation. Importantly, the CDK12 mutation observed in the patient may be indicative of the need for further work-up to consider chemotherapy rather than administering poly (adenosine diphosphate-ribose) polymerase inhibitors. Taken together, this is the first report of pediatric PFA ependymoma with extraneural metastases, wherein we clarified the diagnostic procedures of this newly identified PFA ependymoma and provided new cues to study the invasiveness of this disease and treatment selection for such patients.

Extra-Neural Metastases From Primary Intracranial Ependymomas: A Systematic Review. Front Oncol 2022; 12:831016. [PMID: 35574408 PMCID: PMC9093681 DOI: 10.3389/fonc.2022.831016] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Accepted: 03/28/2022] [Indexed: 11/13/2022] Open
Abstract
Background Primary intracranial ependymomas (IE) are rare brain tumors rarely metastasizing outside the central nervous system. We systematically reviewed the literature on extra-neural metastases from primary IEs. Methods PubMed, Scopus, Web-of-Science, and Cochrane were searched following the PRISMA guidelines to include studies of extra-neural metastases from primary IEs. Clinical features, management strategies, and survival were analyzed. Results We collected 48 patients from 43 studies. Median age was 13 years (range, 2-65). Primary IEs were frequently located in the parietal (22.9%) and frontal (16.7%) lobes, and mostly treated with resection (95.8%) and/or radiotherapy (62.5%). Most IEs were of grade-III (79.1%), and few of grade-I (6.3%) or grade-II (14.6%). 45 patients experienced intracranial recurrences, mostly treated with resection (86.7%), radiotherapy (60%), and/or chemotherapy (24.4%). Median time-interval from primary IEs was 28 months (range, 0-140). Most extra-neural metastases were diagnosed at imaging (37.5%) or autopsy (35.4%). Extra-neural metastases were multifocal in 38 patients (79.1%), mostly involving cervical or hilar lymph-nodes (66.7%), lung/pleura (47.9%), and/or scalp (29.1%). Surgical resection (31.3%), chemotherapy (31.3%) and locoregional radiotherapy (18.8%) were the most common treatments for extra-neural metastases, but 28 (58.3%) patients were not treated. At last follow-up, 37 patients died with median overall-survivals from primary IEs of 36 months (range, 1-239), and from extra-neural metastases of 3 months (range, 0.1-36). Overall-survival was significantly longer in patients with grade-I and II IEs (P=0.040). Conclusion Extra-neural metastases from primary IEs are rare, but mostly occur at later disease stages. Multidisciplinary management strategies should be intended mostly for palliation.

Abstract
Tumor blood vessels provide oxygen and necessary nutrients for the tumor, which provides the basis for tumor metastasis. Therefore, tumor angiogenesis plays a very important role in tumor growth and metastasis. In contrast to linear RNAs, circRNAs represent a type of closed-loop RNA with diverse biological functions. At the same time, circRNAs have strong stability, timeliness, tissue specificity and disease specificity. With the rapid development of next-generation sequencing and bioinformatics, there have been an increasing number of studies on circRNAs. At present, a large number of studies have reported that circRNAs regulate tumor growth, invasion, metastasis, tumor metabolism, tumor immunity and other biological functions. Increasing evidence has shown that circRNAs also play an important role in tumor angiogenesis. In this review, we briefly introduced tumor angiogenesis and circRNAs and outlined the main ways that circRNAs affect tumor angiogenesis from multiple aspects. Finally, we further explored the potential clinical application value of circRNAs in the context of tumor angiogenesis.

Abstract
Background Anaplastic ependymoma with extraneural metastases is associated with a poor clinical outcome. Metastatic spread to the parotid gland is a rare clinical entity that requires multidisciplinary intervention. Herein, we present a systematic review of anaplastic ependymoma with extraneural metastases and report on a case with metastases to both parotid glands. Methods Electronic databases were searched from their inception to February 2019. Inclusion criteria included reports of anaplastic ependymoma with extraneural metastasis. Studies were excluded if the tumor grade was not reported. A case illustration is provided. Results The search yielded 15 cases of anaplastic ependymoma with extraneural metastases, including the present case. Mean age at diagnosis was 15 years. The initial tumor location was predominantly supratentorial (93.3%). All cases demonstrated leptomeningeal seeding before extraneural metastasis. Mean survival from initial diagnosis was 4.5 years. Metastasis to the parotid gland occurred in 2 cases, including the present case. We present a 17-year-old female patient who underwent gross total resection of a supratentorial, paraventricular anaplastic ependymoma followed by adjuvant external beam radiation therapy. The patient developed recurrent leptomeningeal seeding, treated with Gamma Knife radiosurgery over a 5-year period. She returned with a parotid mass and cervical lymphadenopathy and underwent parotidectomy and modified radical neck dissection. She continued to experience recurrences, including the left parotid gland, and was ultimately placed in hospice care. Conclusions Anaplastic ependymoma with extraneural metastasis is rare. A combination of repeated surgical resection, radiation therapy, and chemotherapy can be used to manage recurrent and metastatic disease, but outcomes remain poor.

Abstract
Background Ependymomas are relatively uncommon tumors that constitute about 7% of all primary intracranial neoplasms. Among these, high-grade ependymomas are locally aggressive and recur most commonly at the primary site following resection. Ependymomas are also known to be the one glial neoplasm that tends to frequently metastasize inside and outside the central nervous system (CNS) that complicates workup and management. Metastasis due to surgical manipulation is common and neurosurgeons should be well-versed in the most effective methods to remove these tumors in order to avoid such metastases. Case Description Here, we report a case of a 28-year-old female who initially presented with a parenchymal World Health Organization (WHO) grade III anaplastic ependymoma of the occipital lobe without metastasis. After multiple resections, the patient showed no evidence of disease recurrence for 2 years. During follow-up, new metastasis to the frontal lobe as well as to the lung were discovered 2 years after the initial surgery, without recurrence at the tumor's primary site. Conclusions While uncommon, this case demonstrates the possibility for ependymomas to metastasize via cerebrospinal fluid to other locations within the CNS and hematologically to extraneural locations without recurring locally.

Abstract
Antiangiogenic drugs are currently standard of care in adults with renal cell carcinoma (RCC), including translocation RCC. Although antitumor activity and toxicity profile are well known in adults, few data have been reported in children. Here we present the case of a patient diagnosed at 2 years old with a metastatic translocation RCC, consecutively treated with 5 tyrosine kinase inhibitors during 6 years. The antitumor activity and toxic effects are described, and a brief review of the literature is presented.

Abstract
Ependymal tumours in adults are rare, accounting for less than 4% of primary tumours of the central nervous system, and exceptionally metastasise outside the nervous system. In this study, we present a case of anaplastic ependymoma, which developed metastases outside the nervous system less than a year after its clinical onset. A healthy 65-year-old woman suddenly presented with drowsiness of unknown origin, accompanied by ingravescent fatigue, inability to maintain the upright posture, headache, nausea and vomiting. Computed tomography study performed in the emergency department showed the presence of an inhomogeneously hypodense area, with temporoparietal extension and median line deviation. After surgical excision, performed after two days, the bioptic examination demonstrated an anaplastic ependymoma with multiple areas of necrosis. The patient was submitted to adjuvant radiation therapy. At magnetic resonance imaging follow-up, performed three months after surgery, neither local recurrences nor typical 'drop metastases' to the spinal area were observed. Three months later, magnetic resonance imaging control revealed bone metastases and recurrences in the left insula and at the ipsilateral cerebellar hemisphere. Total body computed tomography examination showed metastases in the liver, vertebrae and pelvic bones, and involvement of paratracheal lymph nodes.

Abstract
METHODS Ten consecutive children (0-18 years) who underwent primary tumor resection for a spinal ependymoma between 1980 and 2011 were included in this retrospective study. Gross motor function and activities of daily life were scored according to the Barthel Index. CONCLUSION Three out of six pediatric patients treated for spinal myxopapillary ependymoma are disease-free after 11 to 33 years of follow-up. The other three have progressive disease, after relapses occurring after 4.5, 7, and 20 years, respectively. One out of two patients with grade II ependymoma had progressive disease from 10 years after initial surgery but is in full-time work in spite of widespread metastatic disease after 32 years. One of the two children with grade III tumor died from progressive disease 17 years from primary diagnosis, while the last one is tumor-free after 19 years. The quality of life is good for three of the four patients with widespread disease, and they are managed conservatively aiming at symptomatic treatment intervention if necessary. We strongly advocate lifelong follow-up for children treated for spinal ependymomas.
