Abstract :
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 per-formed. 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 inci-dence 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 dur-ing 2006 to 2014, which indicated the urgent need for free regular screening for high-risk populations by the govern-ment.
