The burden of prostate cancer in North Africa and Middle East, 1990–2019: Findings from the global burden of disease study

Abstract

Background: Prostate cancer (PCa) is the second most prevalent cancer among men worldwide. This study presents estimates of PCa prevalence, incidence, death, years-of-life-lost (YLLs), years-lived-with-disability (YLDs), disability-adjusted-life-years (DALYs), and the burden attributable to smoking during 1990-2019 in North Africa and Middle East using data of Global Burden of Diseases (GBD) Study 2019. Methods: This study is a part of GBD 2019. Using vital registration and cancer registry data, the estimates on PCa burden were modeled. Risk factor analysis was performed through the six-step conceptual framework of Comparative Risk Assessment. Results: The age-standardized rates (95 UI) of PCa incidence, prevalence, and death in 2019 were 23.7 (18.5-27.9), 161.1 (126.6-187.6), and 11.7 (9.4-13.9) per 100,000 population. While PCa incidence and prevalence increased by 77 and 144 during 1990-2019, respectively, the death rate stagnated. Of the 397 increase in PCa new cases, 234 was due to a rise in the age-specific incidence rate, 79 due to population growth, and 84 due to population aging. The YLLs, YLDs, and DALYs of PCa increased by 2 (-11.8-23.1), 108 (75.5-155.1), and 6 (-8.9-28.1). The death rate and DALYs rate attributable to smoking have decreased 12 and 10, respectively. The DALYs rate attributable to smoking was 37.4 (15.9-67.8) in Lebanon and 5.9 (2.5-10.6) in Saudi Arabia, which were the highest and lowest in the region, respectively. Conclusions: The PCa incidence and prevalence rates increased during 1990-2019; however, the death rate stagnated. The increase in the incidence was mostly due to the rise in the age-specific incidence rate, rather than population growth or aging. The burden of PCa attributable to smoking has decreased in the past 30 years.
