Objective: The aim of this work was to evaluate a pediatric ependymoma protein expression that may be useful as a molecular biomarker candidate for prognosis, correlated with clinical features such as age, gender, histopathological grade, ependymal tumor recurrence and patient survival.
Patients And Methods: Immunohistochemistry assays were performed for GNAO1, ASAH1, IMMT, IPO7, Cyclin D1, P53 and Ki-67 proteins. Kaplan-Meier and Cox analysis were performed for age, gender, histopathological grade, relapse and survival correlation.
Results: We found that three proteins correlate with histopathological grade and relapse; two proteins correlate with survival; one protein does not correlate with any clinical feature.
Conclusion: Our results suggest that, out of the proteins analyzed, five may be considered suitable prognostic biomarkers and one may be considered a predictive biomarker for response to treatment of pediatric ependymoma.

Spinal schistosomiasis masquerading as spinal cord tumor in a 12-year-old male adolescent: A case report.

Spinal schistosomiasis, a rare manifestation of schistosomal infection, can closely mimic the presentation of spinal cord tumors and pose significant diagnostic challenges. We present the case of a 12-year-old boy from northern Ethiopia who experienced progressive back pain, tingling sensations in his lower extremities, and intermittent fever. Initially referred with a presumptive diagnosis of myxopapillary ependymoma for pediatric hematology-oncology evaluation, his marked eosinophilia and history of swimming in local rivers raised suspicion for spinal schistosomiasis.

Significance: Maximal safe resection of brain tumors can be performed by neurosurgeons through the use of accurate and practical guidance tools that provide real-time information during surgery. Current established adjuvant intraoperative technologies include neuronavigation guidance, intraoperative imaging (MRI and ultrasound), and 5-ALA for fluorescence-guided surgery.
Aim: We have developed intraoperative Raman spectroscopy as a real-time decision support system for neurosurgical guidance in brain tumors.

Introduction: POT1 tumor predisposition (POT1-TPD) is an autosomal dominant disorder characterized by increased lifetime malignancy risk. Melanoma, angiosarcoma, and chronic lymphocytic leukemia are the most frequently reported malignancies [1]. Protection of telomeres protein 1 (POT1) is part of the shelterin protein complex to maintain/protect telomeres [2].

Background: Central nervous system (CNS) tumors lead to cancer-related mortality in children. Genetic ancestry-associated cancer prevalence and outcomes have been studied, but is limited.
Methods: We performed genetic ancestry prediction in 1,452 pediatric patients with paired normal and tumor whole genome sequencing from the Open Pediatric Cancer (OpenPedCan) project to evaluate the influence of reported race and ethnicity and ancestry-based genetic superpopulations on tumor histology, molecular subtype, survival, and treatment.

Background: Brain tumors are the deadliest solid tumors in children and adolescents. Most of these tumors are glial in origin and exhibit strong heterogeneity, hampering the development of effective therapeutic strategies. In the past decades, patient-derived tumor organoids (PDT-O) have emerged as powerful tools for modeling tumoral cell diversity and dynamics, and they could then help defining new therapeutic options for pediatric brain tumors.
