the incidence and mortality of cervical cancer in ningbo during 2006-2014, china

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.
