Trend and survival outcome in Taiwan cervical cancer patients: A population-based study

Cervical cancer is one of the most common cancers in Taiwan. The aim of this study was to estimate the incidence of cervical cancer in Taiwan, the relationship between cervical cancer and previous co-morbidities, and the long-term trend of cervical cancer mortality differences in the rest of the world. This study was based on the data of cervical cancer in the National Health Insurance Research Database from 1997 to 2013, and estimated the annual prevalence and incidence of cervical cancer. Joinpoint regression analysis was used to obtain the percentage of annual incidence of cervical cancer, morbidity and survival of patients with cervical cancer by statistical regression analysis. The average annual percentage change (APC) was −7.2, indicating a decrease in the incidence of cervical cancer during the study period. The 1-year, 2-year, and 5-year mortality rates of cervical cancer are relatively stable. The average APC of mortality was higher in high Charlson comorbidity index (CCI) group. This study found that both of prevalence and incidence of cervical cancer descend in Taiwan. The incidence of cervical cancer in Taiwan is increasing with age. The sample survival rate was stable in cervical cancer patients during the study period.
