Abstract: (278 Views)

Background: Identifying the epidemiological aspects of central nervous system (CNS) tumors is the first step in implementing management protocols to control the condition of these tumors. We aimed to examine the epidemiology and histopathology of both benign and malignant tumors of the CNS in one of the referral and university centers in the east of Iran.

Methods: This cross-sectional study was conducted on all files of patients admitted to Qaem Hospital in Mashhad City, Iran, in a period of 10 years from March 2009 to February 2018 with a definitive diagnosis of benign or malignant tumors of the CNS, including tumors of the brain, cerebellum, spinal cord, or meningeal membranes. Information sources included the patients' physical files and the hospital information system (HIS). The statistical software SPSS version 28.0 for Windows (IBM SPSS, Armonk, New York, USA) was used for the statistical analysis.
Results: In total, 775 patients with benign and 771 patients with malignant CNS tumors were included in the study. Regarding epidemiological aspects of benign tumors, the incidence rate of women was almost twice that of men (68.47% versus 31.53%), with an overall average age of 45.31±19.81 years. The most common benign tumors were meningioma (72.77%), followed by schwannoma (13.67%). Regarding malignant brain tumors, the mean age of affected patients was 36.64±19.67 years, with males accounting for 53.04% of cases and females for 46.96%. The most frequent type of tumor was glioblastoma (32.68%), followed by diffuse astrocytoma (16.47%). Both benign and malignant CNS tumors were associated with significant hospital mortality; in-hospital mortality rates for benign and malignant tumors were 10.1% and 17.5%, respectively. Tumor type and its grade were the main determinants of early death in malignant CNS tumors.
Conclusion: The epidemiological characteristics of benign and malignant tumors in our study community were similar to the reports presented in other communities. Knowledge of these characteristics provides the possibility of managing patients and reducing morbidity and mortality related to these tumors.
