Global, regional, and national burdens of bladder cancer in 2017: estimates from the 2017 Global Burden of Disease study

Abstract

<jats:title>Abstract</jats:title> <jats:p>Background The aim of this study is to describe the prevalence and mortality rates of bladder cancer (BCa) using data obtained in the Global Burden of Disease study performed in 2017 (GBD 2017). Methods Data on BCa for 2017, including prevalence, mortality, and disability-adjusted life years (DALYs), were obtained from GBD 2017 at the global, regional, and national levels. We also analyzed the association of BCa burden with the country development level. Results There were 2.63 million BCa cases estimated from the GBD 2017 data, with 200,000 persons dying of BCa, resulting in 3.60 million DALYs in 2017. The age-standardized prevalence rate (ASPR) of BCa was 32.91/100,000 persons, and age-standardized death rate (ASDR) was 2.57/100,000 persons. The ASPR and ASDR of BCa were higher in males than in females, and higher in people older than 60 years. The ASPR and ASDR of BCa were higher in Western Europe and Central Europe than in South Asia, Andean Latin America, and Central Latin America, and higher in countries with a higher sociodemographic index (SDI). Correlation analysis identified that the ASPR and ASDR of BCa were positively correlated with the country SDI (<jats:italic>P</jats:italic> &lt; 0.0001 and <jats:italic>ρ</jats:italic> = 0.68 for ASPR, and <jats:italic>P</jats:italic> = 0.0048 and <jats:italic>ρ</jats:italic> = 0.20 for ASDR). Smoking was the main risk factors attributable to the BCa burden. Conclusion The prevalence and mortality rates of BCa were very high in 2017, especially in high-SDI countries. Smoking-cessation strategies should be strengthened to control the burden associated with BCa.</jats:p>
