Primary Malignant Brain Tumor Trends in Southern Iran, 2001- 2017: An Alarming increase in Glioblastoma

Abstract

Primary Malignant Brain Tumor Trends 2001- 2017: An Alarming Increase In Glioblastoma. Journal of Surgery and Research 5 (2022): 284-295. Abstract Introduction Primary Brain tumors which include a 1.7 percent of all cancers among Data was obtained from Population-based according to WHO 2007 classification of CNS tumors was used for grouping the tumors. Using SPSS, Total Growth Rate (TGR) and Incidence Rate (IR) were calculated to assess the changes overtime. Results A total number of 2130 (male: 890, 41.8% and female: 1240, 58.2%) brain tumor cases from 2001 to 2017 were included in this study. The highest Incidence Rate (IR) was found in ‘unspecified tumors of the brain’ (2.74 per 100000) between 2011 and 2015 followed by ‘Astrocytoma’ (1.34 per 100000) between 2006 and 2010) and ‘Glioblastoma’ (1.25 per 100000) between years 2011 and 2016. Additionally, the Glioblastoma showed the highest IR in those aged between 30 and 59 of years (0.42 per 100000). An upward trend in the rate of brain tumors in the province could be an for more studies to be done especially from the point of view.
