GLIAL TUMORS OF THE BRAIN: GENERAL PRINCIPLES OF DIAGNOSIS AND TREATMENT (REVIEW)

Abstract

Despite significant advances in oncology and neurosurgery, glial brain tumors continue to be an urgent problem of modern healthcare. The proportion of gliomas in the overall structure of glial neoplasms is 40-45%, they are predominantly detected at the age of 30-60 years, affecting the most able-bodied part of the population. Glial neoplasms, as a rule, develop from cells of an astrocytic or oligodendrocyte population and are characterized by rapid growth of the primary tumor node, invasiveness , a tendency to early metastasis, a high recurrence rate , and poor prognosis. The article presents a modern clinical classification of gliomas based on the principles of localization, histogenesis and activity of the tumor process. A characteristic feature of glial brain tumors is invasive growth with no macroscopically clear boundary between the tumor and normal brain tissue.
