The Current State of Adult Glial Tumor Patients' Care in Kazakhstan: Challenges in Diagnosis and Patterns in Survival Outcomes.

Background: The study aimed to analyze the 5-year survival of adult patients with glial tumors and to define characteristics that are associated with the disease outcomes in Kazakhstan.

Methods: Medical records of patients that were surgically treated at the National Center for Neurosurgery during the 5-year period from 2016 to 2020 were collected retrospectively. Patients with a histologically confirmed diagnosis of diffuse astrocytic or oligodendroglial tumor type were included and their survival was assessed with life tables, Kaplan-Meier plot, and Cox regression using STATA 16 statistical software.
