Brain Tumors in Saudi Arabia: An Observational and Descriptive Epidemiological Analysis

Introduction: Brain tumors are one of the major causes of death and morbidity around the world. A prospective existential retrospective observational population-cohort study based on the comprehensive research work on brain tumors in the Saudi population was conducted, with statistics drawn from the Saudi Cancer Registry data collected and published by the Ministry of Health, Saudi Arabia, which is a national document prepared and maintained by the National Health Information Center, from 2006 to 2016. For the analysis of the brain tumor distribution and trends in Saudi Arabian inhabitants, the current study outlined the brain tumor incident rates in the age-standardized incidence rates (ASIRs) and crude incidence rates (CIRs) in the inhabitants of Saudi Arabia by distinct age cohorts, the year of diagnosis, and the core administrative regions of Saudi Arabia. Method: Statistical tools, such as GraphPad Prism and SPSS 2.0, were used for the analyses of the t-test, Kruskal–Wallis test, and descriptive statistics, including the sex ratio and other demographic features. Between 2006 and 2016, Saudi Arabia recorded 1854 and 1293 cases of brain tumors in males and females, respectively. Results: The highest percentage and mean number of brain tumor cases were recorded among males and females in the age group 0–4 years, and the lowest proportion of brain tumor cases were reported among males and females in the higher age group (55–69 years). The highest mean CIR and ASIR were found in the male and female populations of the Riyadh region, and the highest CIR and ASIR sex ratios were found in the Baha and Naj regions of Saudi Arabia, respectively. Males in the Jazan region had the lowest average CIRs and ASIRs. The Baha and Jazan regions of Saudi Arabia recorded the lowest mean CIR and ASIR among females. Conclusion: The Riyadh region had the most significant increases in ASIRs and CIRs for brain tumors in males and females from 2006 to 2016, whereas the Jazan region had the least significant changes in the ASIRs in males and females.
