Abstract:
Objective:To analyze the trend of ovarian cancer incidence in Qidong City from 1972 to 2021 and evaluate the age, period, and cohort effect.Methods:The ovarian cancer incidence data from 1972 to 2021 were extracted from the Qidong Cancer Registry Database, the crude incidence rate (CR), age standardized rate by Chinese population (ASR-C), age standardized rate by world population (ASR-W), and average annual percent change (AAPC) were calculated. The age-period-cohort model was used to analyze the age, period, and birth cohort effects of the ovarian cancer incidence in Qidong from 1972 to 2021.Results:From 1972 to 2021, a total of 1 007 cases of ovarian cancer occurred in Qidong. The AAPC values of CR, ASR-C, and ASR-W were 7.02% , 5.17%, and 5.12% , respectively (all P＜0.001). The time trends showed that, the AAPC values of the age groups of 0-34, 35-44, 45-54, 55-64, 65-74, and over 75 years old were 4.10%, 4.74%, 6.02%, 4.86%, 4.23%, and 5.18%, respectively (all P＜0.05). The age effect showed that the incidence rate of ovarian cancer increased obviously from the 45-49 year-old group, reaching a peak of 20.67/100 000 in the 75-79 year-old group. Compared with the 1992-1996 group, the period of 2002-2021 had significant effects on the incidence rise of ovarian cancer (all P＜0.05), and the incidence rate ratio ( RR) increased with the period: in 2017-2021 the RR was 3.86 (95% CI: 2.72-5.47). Using births from 1952 to 1956 as the reference group, the RR increased slowly from 0.12 (95% CI: 0.02-0.91) in 1892-1896, and peaked in 2007-2011 with an RR of 18.05 (95% CI: 3.51-92.87). The birth cohorts in 1967-2011 had significant effects on the incidence rise of ovarian cancer (all P＜0.05). The Waldχ 2 test of the age-period-cohort model showed that there were significant differences in the age, period, and birth cohort effects (all P＜0.001). Conclusions:The incidence of ovarian cancer in Qidong was on the rise. Age, period, and cohort were the main factors affecting the incidence of ovarian cancer. The middle-aged and elderly women were the focus of ovarian cancer prevention and control.
