Global, regional, and national burden of ovarian cancer and the attributable risk factors in all 194 countries and territories during 2007-2017: A systematic analysis of the Global Burden of Disease Study 2017.

ABSTRACT

BACKGROUND: We estimated the global burden of ovarian cancer (OC) in 194 countries and territories between 2007 and 2017. METHODS: Data were extracted from the Global Burden of Disease (GBD), Injuries, and Risk Factors 2017 study. RESULTS: Globally, 286 126.80 (95% UI = 278 075.38-295 311.41) incident cases, 4.67 million (4.53-4.83) disability-adjusted life-years (DALYs), and 175 981.99 (171 384.15-181 198.43) deaths were reported in 2017. The age-standardized incidence and DALY rates increased by 2.05% and 1.34% during 2007-2017, respectively, while the age-standardized mortality rate decreased by -0.14%. The age-standardized incidence, DALY, and mortality rates in 2017 were the highest in the high socio-demographic index (SDI) quintile, but the largest percentage increase during 2007-2017 was in the low-SDI quintile. Among regions, Central Europe showed the highest 2017 age-standardized incidence, DALY, and mortality rates, whereas South Asia and East Asia showed the largest percentage increases in both rates during 2007-2017. Among countries, India showed the largest percentage increase in age-standardized incidence and DALY rates, whereas Iran showed the largest percentage increase in age-standardized mortality rates. Globally, the largest percentage increase in risk-attributable DALYs was associated with metabolic risk factors (e.g., high fasting plasma glucose levels). CONCLUSION: The global age-standardized incidence, DALYs, and mortality rates of OC remain stable during 2007-2017. However, the low SDI quintile and the greatest burden in South and East Asia, India, and Iran suggested that more targeted strategies should be performed in those regions and countries.
