Background: The purpose of this study was to investigate the incidence and mortality rates of cervical cancer during 2006-2014 in Ningbo, China.
Methods: A retrospective study involved 3418 newly diagnosed cervical cancer cases and 854 death cases were performed. All cases were registered in Cancer Registry Center of Ningbo Centers for Disease Control and Prevention. Results were expressed as standardized age-specific cancer incidence/mortality rates with confidence intervals. All P-values presented were two-sided and the statistical significance was set at P<0.05.
Results: The crude incidence rate was 34.35 per 100000 in females aged 50-54 years. Females aged 80-84 years had the highest crude mortality rates, which were 12.91 per 100000. The average age-standardized incidence and mortality rates by Chinese Standard Population were 6.29 and 1.49 per 100000, respectively. The average age-standardized incidence and mortality rates by World Standard Population were 8.02 and 1.91 per 100000, respectively. The incidence trend graph showed that annual percent change (APC) increased rapidly by 30.2% (P<0.01) during 2006-2014, while the mortality trend graph indicated a rapid increase in mortality annually by 8.8% (P<0.01) during 2006-2014.
Conclusion: We observed an increased trend for both incidence and mortality rates of cervical cancer in Ningbo during 2006 to 2014, which indicated the urgent need for free regular screening for high-risk populations by the government.
