Early Postoperative Adverse Events (≤ 30 Days) in Spinal Oncology: Defining the Incidence, Severity, and Predictors in a Mixed Prospective Cohort Including Intradural and Metastatic Spinal Tumors

International Journal of Cancer, EarlyView.
ABSTRACT Complication reporting in spinal tumor surgery remains inconsistently defined. We aimed to quantify the incidence, severity, and spectrum of early (≤ 30 days) postoperative adverse events (AEs) in spinal tumor surgery and to identify predictors of overall and serious complications using standardized severity grading.

Cystic with mural nodule: Unusual radiological presentation of supratentorial anaplastic ependymoma

Journal of Pediatric Neurosciences, 2012
Supratentorial anaplastic ependymoma is an uncommon tumor which can rarely present as a cyst with mural nodule on imaging. Authors present this unusual radiological appearance of supratentorial extraventricular anaplastic ependymoma in a 9-year-old boy.

The FGF/FGFR System in the Biology and Therapeutic Landscape of Pediatric CNS Tumors

Medicinal Research Reviews, EarlyView.
ABSTRACT Central nervous system (CNS) tumors are the most common solid malignancies in children, comprising a highly heterogeneous group of neoplasms defined by distinct molecular alterations and clinical behaviors. Advances in molecular genetics have underscored the relevance of specific signaling pathways in driving pediatric tumorigenesis, among ...

Cervicodorsal intramedullary ependymoma presenting with spontaneous intratumoral bleed and acute quadriparesis

Journal of Spinal Surgery, 2019
Ependymomas are the most common intramedullary spinal cord tumors in adults and account for 1–5% of spinal tumors. The presence of hemorrhage within the spinal ependymoma is not uncommon on imaging studies, however an ependymoma of the cervicodorsal ...

Interlaboratory performance testing on EPIC v2.0 CNS tumor profiling demonstrates high reproducibility of tumor classification but reveals the need for harmonized copy number variation reporting

Brain Pathology, EarlyView.
Using the Infinium MethylationEPIC v2.0 array and Heidelberg Brain Tumor Classifier v12.8, 24 international laboratories achieved highly reproducible CNS tumor classification (97.9% correct; median β‐correlation r = 0.99), while copy number variation interpretation showed substantial interlaboratory variability, highlighting the need for harmonized CNV

AOSNP‐ADAPTR resource level‐based recommendations on practical diagnostic strategies for medulloblastomas and other embryonal tumors

Brain Pathology, EarlyView.
Resource level‐based recommendations on practical diagnostic strategies for medulloblastomas and other CNS embryonal tumors are provided. Abstract WHO CNS5 mandates integrated histo‐molecular classification of medulloblastomas (MBs) and other CNS embryonal tumors. However, advanced molecular diagnostics remain inaccessible in many low‐ and lower‐middle‐
