Incidence and Mortality of Cancers in Female Genital Organs - China, 2022.

INTRODUCTION: This study presented the incidence and mortality rates of cancers affecting the female genital organs in China, along with their trends spanning from 2010 to 2018.

METHODS: 700 population-based cancer registries provided relevant cancer incidence and mortality data for the year 2018. Among these, 106 registries had continuous monitoring data suitable for trend analysis from 2010 to 2018. We focused specifically on cancers affecting female genital organs (ICD10=C51-C54, C56) and projected their incidences and mortalities in China for 2022 based on data from 2018 and the trends observed from 2010 to 2018. Age-standardized incidence rate (ASIR) and mortality rate (ASMR) were calculated using Segi's world standard population.

RESULTS: In 2022, there were an estimated 296,300 new cases and 104,900 deaths from female cancers in China. ASIRs for vulva (C51), vagina (C52), cervix uteri (C53), corpus uteri (C54), and ovary (C56) were 0.32, 0.23, 13.83, 6.84, and 5.68 per 100,000 population. ASIRs for corpus uteri and ovary cancers were higher in urban areas. ASMRs for vulva, vagina, cervix, corpus uteri, and ovary cancers were 0.14, 0.08, 4.54, 1.05, and 2.64 per 100,000 population, respectively. ASMR for ovarian cancer was higher in urban areas. ASIRs and ASMRs for most female genital organ cancers increased from 2010 to 2018, although the rate of increase for vulvar and cervical cancers in rural areas has slowed recently.

CONCLUSIONS: Tailored cancer prevention and control programs specific to each region are necessary to address the growing disease burden.
