Abstract
BackgroundCervical cancer is one of the most common cancers among women worldwide. The formulation or evaluation on prevention strategies all require an accurate understanding of the burden for cervical cancer burden. We aimed to report the up-to-date estimates of cervical cancer burden at global, regional, and national levels.MethodsData were extracted from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 study. The counts, age-standardized rates, and percentage changes of incidence, disability-adjusted life-years (DALYs), and death attributed to cervical cancer at the global, regional, and national levels in all 195 countries and territories from 21 regions during 2007 to 2017 by age and by Socio-demographic Index (SDI) were measured. All estimates were reported with 95% uncertainty intervals (UIs).ResultsIn 2017, 601,186 (95% UI 554,455 to 625,402) incident cases of cervical cancer were reported worldwide, which caused 8,061,667 (7,527,014 to 8,401,647) DALYs and 259,671 (241,128 to 269,214) deaths. The age-standardized rates for incidence, DALYs and death decreased by − 2.8% (− 7.8% to 0.6%), − 7.1% [− 11.8% to − 3.9%] and − 6.9% [− 11.5% to − 3.7%] from 2007 to 2017, respectively. The highest age-standardized incidence, DALYs and death rates in 2017 were observed in the low SDI quintile, Oceania, Central and Eastern Sub-Saharan Africa. During 2007 to 2017, only East Asia showed increase in these rates despite not significant. At the national level, the highest age-standardized rates for incidence, DALYs, and death in 2017 were observed in Kiribati, Somalia, Eritrea, and Central African Republic; and Georgia showed the largest increases in all these rates during 2007 to 2017.ConclusionAlthough the age-standardized rates for incidence, DALYs, and death of cervical cancer have decreased in most parts of the world from 2007 to 2017, cervical cancer remains a major public health concern in view of the absolute number of cervical cancer cases, DALYs, and deaths increased during this period. The challenge is more prone to in the low SDI quintile, Oceania, Central and Eastern Sub-Saharan Africa, East Asia, and some countries, suggesting an urgent to promote human papillomavirus vaccination in these regions.

Cervical cancer is one of the most common cancers among women worldwide
In 2017, the highest age-standardized incidence rates of cervical cancer were observed in the low Socio-demographic Index (SDI) quintile (23.5 [21.3 to 26.0] per 100,000 person-years), whereas the lowest rate was observed in the high SDI quintile (9.2 [8.8 to 9.5]) (Fig. 1A)
The highest age-standardized incidence rates of cervical cancer were found in Oceania (47.6 [34.8 to 62.8] per 100,000 person-years), Central SubSaharan Africa (42.9 [31.5 to 52.8]), and Eastern SubSaharan Africa (34.9 [29.8 to 41.4]), while the lowest incidence rates were found in North Africa and Middle East (5.6 [4.9 to 6.2] per 100,000 person-years), Australasia (6.3 [5.3 to 7.4]), and Western Europe (8.3 [7.8 to 8.8]) (Fig. 1A)
Summary
Cervical cancer is one of the most common cancers among women worldwide. The formulation or evaluation on prevention strategies all require an accurate understanding of the burden for cervical cancer burden. We aimed to report the up-to-date estimates of cervical cancer burden at global, regional, and national levels. Cervical cancer is the fourth most frequently diagnosed cancer, and the fourth leading cause of cancer deaths in women. According to the Global Cancer Incidence, Mortality and Prevalence (GLOBOCAN), approximately 570,000 cases and 311,000 deaths of cervical cancer were estimated to have occurred in 2018 worldwide [1]. Compelling evidence confirmed that HPV vaccination programs for the most common hrHPV would prevent approximately 87% of cervical cancer cases worldwide [5]. Effective cervical cancer control planning requires an accurate estimation of this disease
