Introduction: Ependymoma is the third most frequent central malignant nervous system tumor in the pediatric age group. There is scarce data in the literature on survival of these patients, especially in upper and lower middle-income countries. We aimed to describe the clinical and demographic characteristics, treatment, and outcome of pediatric patients with ependymoma admitted to a public cancer hospital.
Methods: Retrospective analysis of medical records of patients with ependymoma, admitted to the Pediatric Oncology department (0-20 years) during the period of 2000-2022. Data on patient, disease characteristics, and treatment were analyzed. Overall survival (OS) was calculated using the Kaplan-Meier method.
Results: Seventy-two patients were evaluated; median age at diagnosis was 6.5 years (range: 1-20), 63% were male, 54% of the tumors were in the posterior fossa (PF-EPN), 45% were classified as WHO grade 3, and 68% were operated on in other institutions before referral. Regarding treatment, 72% underwent radiotherapy and 33% of patients underwent chemotherapy. Almost 70% percent of the patients had relapses. The median follow-up time was 5.2 years (Range: 0,1-21,4). The OS in 5 years was 67%. Totally resected tumors had OS in 5 years of 88% (p: 0.028).
Conclusion: The results achieved in this series show a survival gap between UMIC and HIC. Relapses occurred mainly in the first ten years and then reached a plateau, with the majority of patients experiencing endocrinological and neurological sequelae.

Intramedullary schwannomas are a type of benign spinal cord tumor that originates from the Schwann cells of the nerve sheath. They are relatively rare and typically occur within the spinal cord itself, rather than in the surrounding tissue. Treatment options for cervical intramedullary schwannomas include surgical removal of the tumor, radiation therapy, and observation.

Background: Ependymomas of the spinal cord are rare among children and adolescents, and the individual risk of disease progression is difficult to predict. This study aims to evaluate the prognostic impact of molecular typing on pediatric spinal cord ependymomas.
Methods: Eighty-three patients with spinal ependymomas ≤22 years registered in the HIT-MED database (German brain tumor registry for children, adolescents, and adults with medulloblastoma, ependymoma, pineoblastoma, and CNS-primitive neuroectodermal tumors) between 1992 and 2022 were included.

This study aims to evaluate the clinical and radiological features, histopathological characteristics, treatment modalities, and their effectiveness, as well as long-term follow-up results of pediatric spinal ependymomas treated at a single institution. In this retrospective study, medical records of 14 pediatric patients (3 females and 11 males) who were surgically treated for spinal ependymoma in our institution between 1995 and 2020 were reviewed. Data regarding age, gender, presenting symptoms and signs, radiological findings, postoperative status, extent of resection, histopathological grading, recurrence, tumor growth, seeding, and adjuvant treatment were collected and analyzed.

Article Synopsis
- Myxopapillary ependymoma (MPE) is a rare tumor, and the study aimed to investigate its epidemiological features and overall survival factors using data from the SEER database (2004-2015).
- The analysis involved 1,026 MPE cases, highlighting that incidence rates showed no significant trends over time, with higher rates in specific age groups and disparities based on race and gender.
- Key factors influencing overall survival included older age, being widowed, lack of surgery, and the impact of radiotherapy, emphasizing the need for further research to better understand these relationships.

Article Synopsis
- Pediatric intracranial tumors at the skull base are rare, challenging to treat due to complex anatomy, and lack substantial clinical evidence, prompting a study on surgical approaches and outcomes.
- The study involved 12 children under 18 who underwent skull base surgery from 2017 to 2023, analyzing demographics, tumor details, surgical methods, and survival rates.
- Results indicated a predominance of female patients, varying tumor locations and types, with 58.3% achieving gross or near-total resection; however, 33.3% of patients died from tumor progression within an average of 15 months.
