Abstract

Intracranial tumors constitute 85-90% of all primary central nervous system (CNS) tumors. Gliomas account for approximately 70% of primary cerebral tumors in adults and have an incidence of approximately 6/100,000. Glial neoplasms originate from glial cells. Subtypes of glial cells include astrocytes, ependymal cells, and oligodendrocytes. Mutations are often seen in these highly proliferative cells in the brain due to ongoing gliogenesis and neurogenesis, and conversion to tumor stem cells is observed. The classification of central nervous system (CNS) tumors was revised by the World Health Organization (WHO) in 2016 using molecular parameters. As a result of the use of molecular parameters in the WHO-2016 CNS tumors classification, studies to determine the biological behavior of tumors with new neuroradiological imaging methods have accelerated. In this review, short pathological and molecular features and detailed radiological findings of gliomas in accordance with the WHO-2016 CNS tumors classification are presented under separate titles.

Özet

İntrakraniyal tümörler tüm primer santral sinir sistemi tümörlerinin %85-90’ini oluştururlar. Gliomlar erişkinlerdeki primer serebraltümörlerinin yaklaşık %70’ini oluşturmaktadır ve insidansı yaklaşık olarak 6/100.000’dir. Glial neoplazmlar, glial hücrelerden kökenalır. Glial hücrelerin alt tipleri arasında astrositler, ependimal hücreler, oligodendrositler yer almaktadır. Beyinde süregiden gliogenezve nörogenez nedeniyle hayli proliferatif olan bu hücrelerde sıklıkla mutasyonlar görülmekte ve tümör kök hücrelerine dönüşümizlenmektedir. Santral sinir sistemi (SSS) tümörlerinin sınıflandırılması, Dünya Sağlık Örgütü (DSÖ) tarafından 2016 yılında molekülerparametreler kullanılarak yeniden düzenlenmiştir. Özellikle DSÖ-2016 SSS tümörleri sınıflamasında moleküler parametrelerin önplana çıkması sonucunda yeni nöroradyolojik görüntüleme yöntemleri ile tümörlerin biyolojik davranışlarını belirlemeye yönelikçalışmalar hız kazanmıştır. Derlemede Gliomların, DSÖ-2016 SSS tümörleri sınıflamasına uygun olarak kısa patolojik, molekülerözellikleri ve ayrıntılı radyolojik bulguları ayrı başlıklar halinde anlatılmaktadır
