[The classification of nervous system tumors]

Area of Science:

• Neuropathology
• Oncology
• Medical Informatics

Context:

• The classification of nervous system tumors requires updates to reflect current understanding and diagnostic capabilities.
• Existing systems, including the WHO's 1993 classification and ICD-10, provide a foundation but need refinement.
• The Laboratory of Pathomorphology at Burdenko Research Institute has extensive experience informing this revision.

Purpose:

• To present a revised classification for tumors of the nervous system.
• To critically review and integrate existing international classifications.
• To adapt these classifications based on practical experience from a leading neurosurgical institute.

Summary:

• The proposed classification is based on the WHO's 1993 International Histological Classification of Tumors of the Nervous System and the ICD-10 morphology section.
• It incorporates critical review and practical experience from the Laboratory of Pathomorphology, Burdenko Research Institute.
• This revised system aims to unify neurosurgical data across Russian clinics.

Impact:

• Facilitates a unified approach to neuro-oncological data within Russia.
• Enhances the accuracy and reliability of statistical data on nervous system tumors.
• Provides a standardized framework for neuropathologists and neurosurgeons.
