Abstract: Objective This study aimed to analyze the incidence and mortality of cervical cancer in tumor registration areas of Yunnan province in 2020,as well as the trend of incidence and mortality from 2012 to 2020,in order to provide a basis for the prevention and treatment of cervical cancer in Yunnan province. Methods The data of cervical cancer incidence and mortality were collected and sorted out in tumor registration areas of Yunnan province from 2012 to 2020.The crude incidence,crude mortality,age-standardized incidence rate by World standard population(ASIRW)(referred to the World standard incidence),age-standardized mortality rate by World standard population(ASMRW)(referred to the World standard mortality)and other indicators of cervical cancer in 2020 were statistically analyzed according to the urban and rural areas.The annual percent change(APC)was used to evaluate the changing trend of cervical cancer incidence and mortality from 2012 to 2020,and the GM(1,1)model was used to predict the crude incidence and ASIRW from 2021 to 2025. Results In 2020,there were 2 426 new cases of cervical cancer in tumor registration area of Yunnan province,ranking fifth in the incidence of female malignant tumors.The crude incidence and ASIRW were 15.83/100,000 and 11.16/100,000,respectively.There were 831 deaths from cervical cancer,ranking sixth deaths of female malignant tumors.The crude mortality and ASMRW were 5.42/100,000 and 3.52/100,000,respectively.ASIRW was higher in rural areas(11.86/100,000)than that in urban areas(9.11/100,000).ASMRW was slightly higher in urban areas(3.63/100,000)than that in rural areas(3.48/100,000).The age-specific incidence of cervical cancer increased rapidly after the age of 20,and reached a peak in the 55-59 age group;The age-specific mortality of cervical cancer increased rapidly after the age of 35,reaching a peak in the 75-79 age group.ASIRW of cervical cancer in Yunnan province from 2012 to 2020 showed a downward trend with annual changes(APC=-7.54%,95% CI:-13.19%-1.53%),and the trend change was statistically significant(P＜0.05).The prediction of the GM(1,1)model showed that the crude incidence and ASIRW of cervical cancer in Yunnan province would continue to decline from 2021 to 2025. Conclusion The incidence and mortality of cervical cancer are relatively low in Yunnan province,but it is still a common malignant tumor in women.The incidence of cervical cancer in Yunnan province is showing a trend of becoming younger,and rural women are the key population for prevention and treatment.
