DNA Virus Detection in Olfactory Neuroblastomas Using Targeted Enrichment NGS. [PDF]

Neuropathology
ABSTRACT A variety of malignancies can be found in the sinonasal tract including the nasal cavity, paranasal sinuses, and skull base. Many of these are attributed to viruses, for example, carcinomas with the presence of transcriptionally active high‐risk human papillomavirus, as well as Epstein–Barr virus associated malignant lymphoepithelial carcinoma

The Endoscopic Versus Open Approach for Anterior Skull Base Tumors: A Systematic Review of Comparative Outcomes and a Framework for Surgical Selection. [PDF]

Neurol Res Int
Background Anterior skull base tumors (ASBTs) pose significant surgical challenges due to their proximity to critical neurovascular structures. Surgical management has evolved with the adoption of both endoscopic and open approaches. This systematic review synthesizes evidence comparing these approaches in terms of complications, outcomes, and ...

Hyams Grade and Ki-67 as Predictive Factors for Primary Treatment Failure in Olfactory Neuroblastoma. [PDF]

Laryngoscope
The aim of the present study was to investigate the influence of various prognostic parameters on the occurrence of primary tumor progression and/or tumor recurrence (TPR) in esthesioneuroblastoma after primary curative therapy in a single center. Time to first TPR in esthesioneuroblastoma was significantly shorter in cases with a younger age and ...
