title: Epidemiology of Malignant and Non-Malignant Primary Brain Tumors in Jordan.
abstract: BACKGROUND
  There is lack of knowledge on the epidemiological characteristics of brain tumors in Middle Eastern countries. The objective of this study was to study the epidemiological features of primary brain tumors in Jordan.
  
  
  METHODS
  We conducted a prospective cohort study incorporating data from 16 hospitals in Jordan during a 1 year period (May 1, 2011-April 30, 2012). All primary brain tumors diagnosed in Jordan during the study period were identified. The following parameters were retrieved from patients' files: age, gender, histological type, and location. The demographic data of the country was obtained from the National Department of Statistics.
  
  
  RESULTS
  A total of 313 primary brain tumors were identified during the study period. The incidence of primary brain tumors in Jordan among the general population was 5.01 per 100,000 person-years (5.38 in females and 4.65 in males). The incidence in pediatric, adult, and elderly patients was 2.09, 7.29, and 14.38 per 100,000 person-years, respectively. The most common histological types were meningioma (26.2%), glioblastoma (18.9%), astrocytoma (14.1%), and pituitary adenoma (9.3%).
  
  
  CONCLUSIONS
  The incidence of primary brain tumors in the Jordanian population is relatively low, in part due to the young age of the general population.
